The increase of adhesion is usually seen as the objective when applying crop protection products, while bouncing and shattering are seen as detrimental to spray retention. However, observation of drop impacts using high speed shadow graphy shows that fragmentation can occur in Wenzel wetting regime. In this case, a part of the drop sticks on the surface, what contributes to retention. Using simultaneous measurements of drop impacts with high speed imaging and of retention with fluorometry for 3 spray mixtures on excised barley leaves allowed us to observe that about 50% of the drops fragmented in Wenzel state remain on the leaf. Depending on spray mixture, these impact outcomes accounted for 25 to 50% of retention, the higher contribution being correlated with bigger VMD (Volume Median Diameter). This contribution is non-negligible and should be considered when a modelling of spray retention process is performed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drop%20impact" title="drop impact">drop impact</a>, <a href="https://publications.waset.org/abstracts/search?q=retention" title=" retention"> retention</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorometry" title=" fluorometry"> fluorometry</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20speed%20imaging" title=" high speed imaging"> high speed imaging</a> </p> <a href="https://publications.waset.org/abstracts/47237/effect-of-drop-impact-behavior-on-spray-retention" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47237.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">381</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Mathieu Stability of Offshore Buoyant Leg Storage and Regasification Platform</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Chandrasekaran">S.

Kiran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Increasing demand for large-sized Floating, Storage and Regasification Units (FSRUs) for oil and gas industries led to the development of novel geometric form of Buoyant Leg Storage and Regasification Platform (BLSRP). BLSRP consists of a circular deck supported by six buoyant legs placed symmetrically with respect to wave direction. Circular deck is connected to buoyant legs using hinged joints, which restrain transfer of rotational response from the legs to deck and vice-versa. Buoyant legs are connected to seabed using taut moored system with high initial pretension, enabling rigid body motion in vertical plane. Encountered environmental loads induce dynamic tether tension variations, which in turn affect stability of the platform. The present study investigates Mathieu stability of BLSRP under the postulated tether pullout cases by inducing additional tension in the tethers. From the numerical studies carried out, it is seen that postulated tether pullout on any one of the buoyant legs does not result in Mathieu type instability even under excessive tether tension. This is due to the presence of hinged joints, which are capable of dissipating the unbalanced loads to other legs. However, under tether pullout of consecutive buoyant legs, Mathieu-type instability is observed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=offshore%20platforms" title="offshore platforms">offshore platforms</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=postulated%20failure" title=" postulated failure"> postulated failure</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20tether%20tension" title=" dynamic tether tension"> dynamic tether tension</a> </p> <a href="https://publications.waset.org/abstracts/76103/mathieu-stability-of-offshore-buoyant-leg-storage-and-regasification-platform" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76103.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">179</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Direct Measurements of the Electrocaloric Effect in Solid Ferroelectric Materials via Thermoreflectance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Layla%20Farhat">Layla Farhat</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Bardoux"> Mathieu Bardoux</a>, <a href="https://publications.waset.org/abstracts/search?q=St%C3%A9phane%20Longuemart"> Stéphane Longuemart</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziad%20Herro"> Ziad Herro</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhak%20Hadj%20Sahraoui"> Abdelhak Hadj Sahraoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrocaloric (EC) effect refers to the isothermal entropy or adiabatic temperature changes of a dielectric material induced by an external electric field.

However, unlike listed companies that can assess their values based on market shares, most Small and Medium Enterprises (SMEs) which are non-listed cannot have direct and live access to this critical information. Traditional accounting reports only give limited insights to SME decision-makers about the real impact of their day-to-day decisions on the company’s performance and value. Most of the time, an SME’s financial valuation is made one time a year as the associated process is time and resource-consuming, requiring several months and external expertise to be completed. To solve this issue, we propose in this paper a value-oriented metamodel that enables real-time and dynamic assessment of the SME’s value based on the large definition of their assets. These assets cover a wider scope of resources of the company and better account for immaterial assets. The proposal, which is illustrated in a case study, discusses the benefits of incorporating assets in the SME valuation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SME" title="SME">SME</a>, <a href="https://publications.waset.org/abstracts/search?q=metamodel" title=" metamodel"> metamodel</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20support%20system" title=" decision support system"> decision support system</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20valuation" title=" financial valuation"> financial valuation</a>, <a href="https://publications.waset.org/abstracts/search?q=assets" title=" assets"> assets</a> </p> <a href="https://publications.waset.org/abstracts/155809/a-value-oriented-metamodel-for-small-and-medium-enterprises-decision-making" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155809.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Vibration and Parametric Instability Analysis of Delaminated Composite Beams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Szekr%C3%A9nyes">A.

It is shown that during the vibration of composite beams the delaminated parts are subjected to the parametric excitation. This can lead to the dynamic buckling during the motion of the structure. The equation of motion includes time-dependent stiffness and so it leads to a system of Mathieu-Hill differential equations. The free vibration analysis of beams is carried out in the usual way by using beam finite elements. The dynamic buckling problem is investigated locally, and the critical buckling forces are determined by the modified harmonic balance method by using an imposed time function of the motion. The stability diagrams are created, and the numerical predictions are compared to experimental results. The most important findings are the critical amplitudes at which delamination buckling takes place, the stability diagrams representing the instability of the system, and the realistic mode shape prediction in contrast with the unrealistic results of models available in the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=delamination" title="delamination">delamination</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20vibration" title=" free vibration"> free vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=parametric%20excitation" title=" parametric excitation"> parametric excitation</a>, <a href="https://publications.waset.org/abstracts/search?q=sweep%20excitation" title=" sweep excitation"> sweep excitation</a> </p> <a href="https://publications.waset.org/abstracts/47603/vibration-and-parametric-instability-analysis-of-delaminated-composite-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47603.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">345</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Restraint and Seclusion: Individual and Environmental Characteristics of the Educators Super Users</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Caroline%20A.%20Mathieu">Caroline A.

In order to manage youth violence and protect youth safety or their own, educators can resort to restraint and seclusion (R&S) strategies. To our best knowledge, in the literature, no study was found on the topic of R&S super users either in psychiatry or in a rehabilitation center. The objective of this study is to explore the differences between R&S super users and normal users among educators in terms of individual and environmental characteristics, over an eight weeks period. The 278 participants were volunteers recruited from 36 units that foster around 8 to 12 youths per unit, in a suburb of Montreal; Quebec, Canada. The results indicate that among the variables that were studied, only fear of violence and past exposure to violence at work characterized the R&S super users. These results suggest that exposure to violence in the workplace might increase the anticipation and fear of violence from a youth; this is concordant with the results indicating that these variables are the ones separating normal users from super users. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seclusion%20and%20restraint" title="seclusion and restraint">seclusion and restraint</a>, <a href="https://publications.waset.org/abstracts/search?q=violence" title=" violence"> violence</a>, <a href="https://publications.waset.org/abstracts/search?q=youth" title=" youth"> youth</a>, <a href="https://publications.waset.org/abstracts/search?q=educators" title=" educators"> educators</a> </p> <a href="https://publications.waset.org/abstracts/113251/restraint-and-seclusion-individual-and-environmental-characteristics-of-the-educators-super-users" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113251.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">193</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Controller Design and Experimental Evaluation of a Motorized Assistance for a Patient Transfer Floor Lift</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Donatien%20Callon">Donatien Callon</a>, <a href="https://publications.waset.org/abstracts/search?q=Ian%20Lalonde"> Ian Lalonde</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Nadeau"> Mathieu Nadeau</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandre%20Girard"> Alexandre Girard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Patient transfer is a challenging, critical task because it exposes caregivers to injury risks. Available transfer devices, like floor lifts, lead to improvements but are far from perfect. They do not eliminate the caregivers’ risk of musculoskeletal disorders, and they can be burdensome to use due to their poor maneuverability. This paper presents a new motorized floor lift with a single central motorized wheel connected to an instrumented handle. Admittance controllers are designed to 1) improve the device maneuverability, 2) reduce the required caregiver effort, and 3) ensure the security and comfort of patients. Two controller designs, one with a linear admittance law and a non-linear admittance law with variable damping, were developed and implemented on a prototype. Tests were performed on seven participants to evaluate the performance of the assistance system and the controllers. The experimental results show that 1) the motorized assistance with the variable damping controller improves maneuverability by 28%, 2) reduces the amount of effort required to push the lift by 66%, and 3) provides the same level of patient comfort compared to a standard unassisted floor lift. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=floor%20lift" title="floor lift">floor lift</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20robot%20interaction" title=" human robot interaction"> human robot interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=admittance%20controller" title=" admittance controller"> admittance controller</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20admittance" title=" variable admittance"> variable admittance</a> </p> <a href="https://publications.waset.org/abstracts/176308/controller-design-and-experimental-evaluation-of-a-motorized-assistance-for-a-patient-transfer-floor-lift" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176308.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">111</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Thermal and Dielectric Breakdown Criterium for Low Voltage Switching Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Merciris">Thomas Merciris</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Masquere"> Mathieu Masquere</a>, <a href="https://publications.waset.org/abstracts/search?q=Yann%20Cressault"> Yann Cressault</a>, <a href="https://publications.waset.org/abstracts/search?q=Pascale%20Petit"> Pascale Petit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The goal of an alternative current (AC) switching device is to allow the arc (created during the opening phase of the contacts) to extinguish at the current zero. The plasma temperature rate of cooling down, the electrical characteristic of the arc (current-voltage), and the rise rate of the transient recovery voltage (TRV) are critical parameters which influence the performance of a switching device. To simulate the thermal extinction of the arc and to obtain qualitative data on the processes responsible for this phenomenon, a 1D MHD fluid model in the air was developed and coupled to an external electric circuit. After thermal extinction, the dielectric strength of the hot air (< 4kK) was then estimated by the Bolsig+ software and the critical electric fields method with the temperature obtained by the MHD simulation. The influence of copper Cu and silver Ag vapors was investigated on the thermal and dielectric part of the simulation with various current forms (100A to 1kA). Finally, those values of dielectric strength have been compared to the experimental values obtained in the case of two separating silver contacts. The preliminary results seem to indicate the dielectric strength after multiples hundreds of microseconds is the same order of magnitude as experimentally found. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MHD%20simulation" title="MHD simulation">MHD simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric%20recovery" title=" dielectric recovery"> dielectric recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=Bolsig%2B" title=" Bolsig+"> Bolsig+</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20vapors" title=" silver vapors"> silver vapors</a>, <a href="https://publications.waset.org/abstracts/search?q=copper%20vapors" title=" copper vapors"> copper vapors</a>, <a href="https://publications.waset.org/abstracts/search?q=breakers" title=" breakers"> breakers</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20arc" title=" electric arc"> electric arc</a> </p> <a href="https://publications.waset.org/abstracts/156604/thermal-and-dielectric-breakdown-criterium-for-low-voltage-switching-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156604.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">115</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Energy Management System and Interactive Functions of Smart Plug for Smart Home</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Win%20Thandar%20Soe">Win Thandar Soe</a>, <a href="https://publications.waset.org/abstracts/search?q=Innocent%20Mpawenimana"> Innocent Mpawenimana</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Di%20Fazio"> Mathieu Di Fazio</a>, <a href="https://publications.waset.org/abstracts/search?q=C%C3%A9cile%20Belleudy"> Cécile Belleudy</a>, <a href="https://publications.waset.org/abstracts/search?q=Aung%20Ze%20Ya"> Aung Ze Ya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Intelligent electronic equipment and automation network is the brain of high-tech energy management systems in critical role of smart homes dominance. Smart home is a technology integration for greater comfort, autonomy, reduced cost, and energy saving as well. These services can be provided to home owners for managing their home appliances locally or remotely and consequently allow them to automate intelligently and responsibly their consumption by individual or collective control systems. In this study, three smart plugs are described and one of them tested on typical household appliances. This article proposes to collect the data from the wireless technology and to extract some smart data for energy management system. This smart data is to quantify for three kinds of load: intermittent load, phantom load and continuous load. Phantom load is a waste power that is one of unnoticed power of each appliance while connected or disconnected to the main. Intermittent load and continuous load take in to consideration the power and using time of home appliances. By analysing the classification of loads, this smart data will be provided to reduce the communication of wireless sensor network for energy management system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20management" title="energy management">energy management</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20profile" title=" load profile"> load profile</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20plug" title=" smart plug"> smart plug</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20network" title=" wireless sensor network"> wireless sensor network</a> </p> <a href="https://publications.waset.org/abstracts/69157/energy-management-system-and-interactive-functions-of-smart-plug-for-smart-home" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69157.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">273</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> The Optimization of an Industrial Recycling Line: Improving the Durability of Recycled Polyethyene Blends</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alae%20Lamtai">Alae Lamtai</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Elkoun"> Said Elkoun</a>, <a href="https://publications.waset.org/abstracts/search?q=Hniya%20Kharmoudi"> Hniya Kharmoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Robert"> Mathieu Robert</a>, <a href="https://publications.waset.org/abstracts/search?q=Carl%20Diez"> Carl Diez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study applies Taguchi's design of experiment methodology and grey relational analysis (GRA) for multi objective optimization of an industrial recycling line. This last is composed mainly of a mono and twin-screw extruder and a filtration system. Experiments were performed according to L₁₆ standard orthogonal array based on five process parameters, namely: mono screw design, screw speed of the mono and twin-screw extruder, melt pump pressure, and filter mesh size. The objective of this optimization is to improve the durability of the Polyethylene (PE) blend by decreasing the loss of Stress Crack resistance (SCR) using Notched Crack Ligament Stress (NCLS) test and Unnotched Crack Ligament Stress (UCLS) in parallel with increasing the gain of Izod impact strength of the Polyethylene (PE) blend before and after recycling. Based on Grey Relational Analysis (GRA), the optimal setting of process parameters was identified, and the results indicated that the mono-screw design and screw speed of both mono and twin-screw extruder impact significantly the mechanical properties of recycled Polyethylene (PE) blend. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taguchi" title="Taguchi">Taguchi</a>, <a href="https://publications.waset.org/abstracts/search?q=recycling%20line" title=" recycling line"> recycling line</a>, <a href="https://publications.waset.org/abstracts/search?q=polyethylene" title=" polyethylene"> polyethylene</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20crack%20resistance" title=" stress crack resistance"> stress crack resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=Izod%20impact%20strength" title=" Izod impact strength"> Izod impact strength</a>, <a href="https://publications.waset.org/abstracts/search?q=grey%20relational%20analysis" title=" grey relational analysis"> grey relational analysis</a> </p> <a href="https://publications.waset.org/abstracts/184105/the-optimization-of-an-industrial-recycling-line-improving-the-durability-of-recycled-polyethyene-blends" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184105.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">83</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Improved Thermal Comfort in Cabin Aircraft with in-Seat Microclimate Conditioning Module</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Le%20Cam">Mathieu Le Cam</a>, <a href="https://publications.waset.org/abstracts/search?q=Tejaswinee%20Darure"> Tejaswinee Darure</a>, <a href="https://publications.waset.org/abstracts/search?q=Mateusz%20Pawlucki"> Mateusz Pawlucki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Climate control of cabin aircraft is traditionally conditioned as a single unit by the environmental control system. Cabin temperature is controlled by the crew while passengers of the aircraft have control on the gaspers providing fresh air from the above head area. The small nozzles are difficult to reach and adjust to meet the passenger’s needs in terms of flow and direction. More dedicated control over the near environment of each passenger can be beneficial in many situations. The European project COCOON, funded under Clean Sky 2, aims at developing and demonstrating a microclimate conditioning module (MCM) integrated into a standard economy 3-seat row. The system developed will lead to improved passenger comfort with more control on their personal thermal area. This study focuses on the assessment of thermal comfort of passengers in the cabin aircraft through simulation on the TAITherm modelling platform. A first analysis investigates thermal comfort and sensation of passengers in varying cabin environmental conditions: from cold to very hot scenarios, with and without MCM installed in the seats. The modelling platform is also used to evaluate the impact of different physiologies of passengers on their thermal comfort as well as different seat locations. Under the current cabin conditions, a passenger of a 50th percentile body size is feeling uncomfortably cool due to the high velocity cabin air ventilation. The simulation shows that the in-seat MCM developed in COCOON project improves the thermal comfort of the passenger. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cabin%20aircraft" title="cabin aircraft">cabin aircraft</a>, <a href="https://publications.waset.org/abstracts/search?q=in-seat%20HVAC" title=" in-seat HVAC"> in-seat HVAC</a>, <a href="https://publications.waset.org/abstracts/search?q=microclimate%20conditioning%20module" title=" microclimate conditioning module"> microclimate conditioning module</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20comfort" title=" thermal comfort"> thermal comfort</a> </p> <a href="https://publications.waset.org/abstracts/132315/improved-thermal-comfort-in-cabin-aircraft-with-in-seat-microclimate-conditioning-module" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132315.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">200</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Emerging Technologies in European Aeronautics: How Collaborative Innovation Efforts Are Shaping the Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nikola%20Radovanovic">Nikola Radovanovic</a>, <a href="https://publications.waset.org/abstracts/search?q=Petros%20Gkotsis"> Petros Gkotsis</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Doussineau"> Mathieu Doussineau</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aeronautics is regarded as a strategically important sector for European competitiveness. It was at the heart of European entrepreneurial development since the industry was born. Currently, the EU is the world leader in the production of civil aircraft, including helicopters, aircraft engines, parts, and components. It is recording a surplus in trade relating to aerospace products, which are exported all over the globe. Also, this industry shows above-average investments in research and development, as demonstrated in the patent activity in this area. The post-pandemic recovery of the industry will partly depend on the possibilities to streamline collaboration in further research and innovation activities. Aeronautics features as one of the often selected priority domains in smart specialisation, which represents the main regional and national approach in developing and implementing innovation policies in Europe. The basis for the selection of priority domains for smart specialisation lies in the mapping of innovative potential, with research and patent activities being among the key elements of this analysis. This research is aimed at identifying characteristics of the trends in research and patent activities in the regions and countries that base their competitiveness on the aeronautics sector. It is also aimed at determining the scope and patterns of collaborations in aeronautics between innovators from the European regions, focusing on revealing new technology areas that emerge from these collaborations. For this purpose, we developed a methodology based on desk research and the analysis of the PATSTAT patent database as well as the databases of R&I framework programmes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aeronautics" title="aeronautics">aeronautics</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20specialisation" title=" smart specialisation"> smart specialisation</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=research" title=" research"> research</a>, <a href="https://publications.waset.org/abstracts/search?q=regional%20policy" title=" regional policy"> regional policy</a> </p> <a href="https://publications.waset.org/abstracts/159377/emerging-technologies-in-european-aeronautics-how-collaborative-innovation-efforts-are-shaping-the-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159377.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">106</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> The Targeting Logic of Terrorist Groups in the Sahel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Bere">Mathieu Bere</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Al-Qaeda and Islamic State-affiliated groups such as Ja’amat Nusra al Islam Wal Muslimim (JNIM) and the Islamic State-Greater Sahara Faction, which is now part of the Boko Haram splinter group, Islamic State in West Africa, were responsible, between 2018 and 2020, for at least 1.333 violent incidents against both military and civilian targets, including the assassination and kidnapping for ransom of Western citizens in Mali, Burkina Faso and Niger, the Central Sahel. Protecting civilians from the terrorist violence that is now spreading from the Sahel to the coastal countries of West Africa has been very challenging, mainly because of the many unknowns that surround the perpetrators. To contribute to a better protection of civilians in the region, this paper aims to shed light on the motivations and targeting logic of jihadist perpetrators of terrorist violence against civilians in the central Sahel region. To that end, it draws on relevant secondary data retrieved from datasets, the media, and the existing literature, but also on primary data collected through interviews and surveys in Burkina Faso. An analysis of the data with the support of qualitative and statistical analysis software shows that military and rational strategic motives, more than purely ideological or religious motives, have been the main drivers of terrorist violence that strategically targeted government symbols and representatives as well as local leaders in the central Sahel. Behind this targeting logic, the jihadist grand strategy emerges: wiping out the Western-inspired legal, education and governance system in order to replace it with an Islamic, sharia-based political, legal, and educational system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=terrorism" title="terrorism">terrorism</a>, <a href="https://publications.waset.org/abstracts/search?q=jihadism" title=" jihadism"> jihadism</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahel" title=" Sahel"> Sahel</a>, <a href="https://publications.waset.org/abstracts/search?q=targeting%20logic" title=" targeting logic"> targeting logic</a> </p> <a href="https://publications.waset.org/abstracts/147717/the-targeting-logic-of-terrorist-groups-in-the-sahel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147717.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Linear and Nonlinear Resonance of Flat Bottom Hole in an Aluminum Plate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Biaou%20Jean-Baptiste%20Kouchoro">Biaou Jean-Baptiste Kouchoro</a>, <a href="https://publications.waset.org/abstracts/search?q=Anissa%20Meziane"> Anissa Meziane</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippe%20Micheau"> Philippe Micheau</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Renier"> Mathieu Renier</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Quaegebeur"> Nicolas Quaegebeur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Numerous experimental and numerical studies have shown the interest of the local defects resonance (LDR) for the Non-Destructive Testing of metallic and composite plates. Indeed, guided ultrasonic waves such as Lamb waves, which are increasingly used for the inspection of these flat structures, enable the generation of local resonance phenomena by their interaction with a damaged area, allowing the detection of defects. When subjected to a large amplitude motion, a nonlinear behavior can predominate in the damaged area. This work presents a 2D Finite Element Model of the local resonance of a 12 mm long and 5 mm deep Flat Bottom Hole (FBH) in a 6 mm thick aluminum plate under the excitation induced by an incident A0 Lamb mode. The analysis of the transient response of the FBH enables the precise determination of its resonance frequencies and the associate modal deformations. Then, a linear parametric study varying the geometrical properties of the FBH highlights the sensitivity of the resonance frequency with respect to the plate thickness. It is demonstrated that the resonance effect disappears when the ratio of thicknesses between the FBH and the plate is below 0.1. Finally, the nonlinear behavior of the FBH is considered and studied introducing geometrical (taken into account the nonlinear component of the strain tensor) nonlinearities that occur at large vibration amplitudes. Experimental analysis allows observation of the resonance effects and nonlinear response of the FBH. The differences between these experimental results and the numerical results will be commented on. The results of this study are promising and allow to consider more realistic defects such as delamination in composite materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=guided%20waves" title="guided waves">guided waves</a>, <a href="https://publications.waset.org/abstracts/search?q=non-destructive%20testing" title=" non-destructive testing"> non-destructive testing</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20field%20testing" title=" dynamic field testing"> dynamic field testing</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20ultrasound%2Fvibration" title=" non-linear ultrasound/vibration"> non-linear ultrasound/vibration</a> </p> <a href="https://publications.waset.org/abstracts/146110/linear-and-nonlinear-resonance-of-flat-bottom-hole-in-an-aluminum-plate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146110.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">134</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Microbial Phylogenetic Divergence between Surface-Water and Sedimentary Ecosystems Drove the Resistome Profiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Okugbe%20Ebiotubo%20Ohore">Okugbe Ebiotubo Ohore</a>, <a href="https://publications.waset.org/abstracts/search?q=Jingli%20Zhang"> Jingli Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Binessi%20Edouard%20Ifon"> Binessi Edouard Ifon</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Nsenga%20Kumwimba"> Mathieu Nsenga Kumwimba</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoying%20Mu"> Xiaoying Mu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dai%20Kuang"> Dai Kuang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhen%20Wang"> Zhen Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji-Dong%20Gu"> Ji-Dong Gu</a>, <a href="https://publications.waset.org/abstracts/search?q=Guojing%20Yang"> Guojing Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Antibiotic pollution and the evolution of antibiotic resistance genes (ARGs) are increasingly viewed as major threats to both ecosystem security and human health, and has drawn attention. This study investigated the fate of antibiotics in aqueous and sedimentary substrates and the impact of ecosystem shifts between water and sedimentary phases on resistome profiles. The findings indicated notable variations in the concentration and distribution patterns of antibiotics across various environmental phases. Based on the partition coefficient (Kd), the total antibiotic concentration was significantly greater in the surface water (1405.45 ng/L; 49.5%) compared to the suspended particulate matter (Kd =0.64; 892.59 ng/g; 31.4%) and sediment (Kd=0.4; 542.64 ng/g; 19.1%). However, the relative abundance of ARGs in surface water and sediment was disproportionate to the abundance of antibiotics concentration, and sediments were the predominant ARGs reservoirs. Phylogenetic divergence of the microbial communities between the surface water and the sedimentary ecosystems potentially played important roles in driving the ARGs profiles between the two distinctive ecosystems. ARGs of Clinical importance; including blaGES, MCR-7.1, ermB, tet(34), tet36, tetG-01, and sul2 were significantly increased in the surface water, while blaCTX-M-01, blaTEM, blaOXA10-01, blaVIM, tet(W/N/W), tetM02, and ermX were amplified in the sediments. cfxA was an endemic ARG in surface-water ecosystems while the endemic ARGs of the sedimentary ecosystems included aacC4, aadA9-02, blaCTX-M-04, blaIMP-01, blaIMP-02, bla-L1, penA, erm(36), ermC, ermT-01, msrA-01, pikR2, vgb-01, mexA, oprD, ttgB, and aac.

However, school staff often feels unqualified to support these students, lacking the preparation, skills and training to meet their needs. Continuing education for these staff is therefore essential to ensure that they can meet the needs of these students. As a result, the Government of Quebec has developed a bilingual (French and English) online training on autism specific to the needs of school staff. Therefore, adequate training for all school staff is likely to provide quality learning opportunities for these students. The research project focuses on the participants' appreciation, contributions, and social validity of the training. More specifically, it aims to: 1) evaluate the knowledge and self-efficacy of the participants, 2) evaluate the social validity and 3) document the evaluation of the ergonomics of the platform hosting the training. The evaluation carried out as part of this descriptive study uses a quantitative method. Data are collected using questionnaires completed online. The analysis of preliminary data reveals that participants' knowledge of autism and their sense of self-efficacy increased significantly. They value the training positively and consider it to be acceptable, appropriate, and suitable. The participants find it important for school staff to take this training. Almost all the items measuring the ergonomics of the platform have averages above 4.57/5. In general, the study shows that the training allows participating of the trainee school staff to improve their knowledge of autism and their sense of self-efficacy with young people with autism. In addition, participants recognize that the training has good social validity and appreciate the online modality. However, these results should be interpreted with caution given the limited number of participants who completed the research project. It is therefore important to continue the research with a larger number of participants to allow an adequate and general representativeness of the social validity, the feeling of competence and the appreciation of the platform. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autism" title="autism">autism</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20training" title=" online training"> online training</a>, <a href="https://publications.waset.org/abstracts/search?q=school%20staff" title=" school staff"> school staff</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20validity" title=" social validity"> social validity</a> </p> <a href="https://publications.waset.org/abstracts/186067/study-on-the-contributions-and-social-validity-of-an-online-autism-training-for-school-staff" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186067.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">37</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Qualitative Inquiry for Understanding Factors Associated to Intergenerational Transmission of Child Maltreatment </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marie-Claude%20Richard">Marie-Claude Richard</a>, <a href="https://publications.waset.org/abstracts/search?q=Amelie%20Bolduc-Mokhtar"> Amelie Bolduc-Mokhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Parent"> Mathieu Parent</a> </p> <p class="card-text"><strong>Abstract:</strong></p> People who have experienced maltreatment in childhood subsequently face many parenting issues of their own, in particular when it comes to distancing themselves from the abusive behaviors they were exposed and had access to positive role models. Few studies have explored the factors explaining the ability to break the generational cycle of child maltreatment. However, deeper knowledge of the factors associated with intergenerational discontinuity could facilitate the development of innovative interventions and increase the preventive potential of existing programs. This poster presentation will be about a better understanding of the intergenerational transmission of maltreatment (IGTM) from the perspective of both youth protection workers and parents receiving child protection services. The data used to meet this goal were collected from a group interview with eight youth protection workers whose caseloads involved IGTM situations and through semi-structured interviews with four parents with a history of child protection services and who were currently receiving such services for at least one of their children. In the view of the youth protection workers, the IGTM refers to everything that is transmitted and not transmitted from one generation to the next within a family. The study participants painted quite a bleak portrait of the families affected by IGTM. However, three main avenues of intervention were mentioned by the participants: working within the network, favoring long-term interventions and being empathic. The results also show that the mothers were in a trajectory of intergenerational discontinuity in child maltreatment. Support from their families and friends as well as from formal support services brought out some possible explanatory factors for intergenerational discontinuity in child maltreatment. From a prevention perspective, developing meaningful and trusting relationships seems a source of resilience for parents who were placed in the care of the child protection system as children. The small number of participants limits the generalizability of these results. The difficulty of recruiting parents is a substantial challenge regarding gaining knowledge on the intergenerational transmission of child maltreatment. Future studies should examine this question and seek to develop effective strategies to help recruit study participants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=child%20maltreatment" title="child maltreatment">child maltreatment</a>, <a href="https://publications.waset.org/abstracts/search?q=intergenerational%20transmission" title=" intergenerational transmission"> intergenerational transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=prevention" title=" prevention"> prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative%20data" title=" qualitative data"> qualitative data</a> </p> <a href="https://publications.waset.org/abstracts/76517/qualitative-inquiry-for-understanding-factors-associated-to-intergenerational-transmission-of-child-maltreatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76517.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">192</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Miniature Fast Steering Mirrors for Space Optical Communication on NanoSats and CubeSats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sylvain%20Chardon">Sylvain Chardon</a>, <a href="https://publications.waset.org/abstracts/search?q=Timot%C3%A9o%20Payre"> Timotéo Payre</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Grardel"> Hugo Grardel</a>, <a href="https://publications.waset.org/abstracts/search?q=Yann%20Quentel"> Yann Quentel</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Thomachot"> Mathieu Thomachot</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%A9rald%20Aigouy"> Gérald Aigouy</a>, <a href="https://publications.waset.org/abstracts/search?q=Frank%20Claeyssen"> Frank Claeyssen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the increasing digitalization of society, access to data has become vital and strategic for individuals and nations. In this context, the number of satellite constellation projects is growing drastically worldwide and is a next-generation challenge of the New Space industry. So far, existing satellite constellations have been using radio frequencies (RF) for satellite-to-ground communications, inter-satellite communications, and feeder link communication. However, RF has several limitations, such as limited bandwidth and low protection level. To address these limitations, space optical communication will be the new trend, addressing both very high-speed and secured encrypted communication. Fast Steering Mirrors (FSM) are key components used in optical communication as well as space imagery and for a large field of functions such as Point Ahead Mechanisms (PAM), Raster Scanning, Beam Steering Mirrors (BSM), Fine Pointing Mechanisms (FPM) and Line of Sight stabilization (LOS). The main challenges of space FSM development for optical communication are to propose both a technology and a supply chain relevant for high quantities New Space approach, which requires secured connectivity for high-speed internet, Earth planet observation and monitoring, and mobility applications. CTEC proposes a mini-FSM technology offering a stroke of +/-6 mrad and a resonant frequency of 1700 Hz, with a mass of 50 gr. This FSM mechanism is a good candidate for giant constellations and all applications on board NanoSats and CubeSats, featuring a very high level of miniaturization and optimized for New Space high quantities cost efficiency. The use of piezo actuators offers a high resonance frequency for optimal control, with almost zero power consumption in step and stay pointing, and with very high-reliability figures > 0,995 demonstrated over years of recurrent manufacturing for Optronics applications at CTEC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fast%20steering%20mirror" title="fast steering mirror">fast steering mirror</a>, <a href="https://publications.waset.org/abstracts/search?q=feeder%20link" title=" feeder link"> feeder link</a>, <a href="https://publications.waset.org/abstracts/search?q=line%20of%20sight%20stabilization" title=" line of sight stabilization"> line of sight stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20communication" title=" optical communication"> optical communication</a>, <a href="https://publications.waset.org/abstracts/search?q=pointing%20ahead%20mechanism" title=" pointing ahead mechanism"> pointing ahead mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=raster%20scan" title=" raster scan"> raster scan</a> </p> <a href="https://publications.waset.org/abstracts/162023/miniature-fast-steering-mirrors-for-space-optical-communication-on-nanosats-and-cubesats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162023.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">80</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Comparison of Peri- and Post-Operative Outcomes of Three Left Atrial Incisions: Conventional Direct, Transseptal and Superior Septal Left Atriotomy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Estelle%20D%C3%A9moulin">Estelle Démoulin</a>, <a href="https://publications.waset.org/abstracts/search?q=Dionysios%20Adamopoulos"> Dionysios Adamopoulos</a>, <a href="https://publications.waset.org/abstracts/search?q=Tornike%20Sologashvili"> Tornike Sologashvili</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Van%20Steenberghe"> Mathieu Van Steenberghe</a>, <a href="https://publications.waset.org/abstracts/search?q=Jalal%20Jolou"> Jalal Jolou</a>, <a href="https://publications.waset.org/abstracts/search?q=Haran%20Burri"> Haran Burri</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Huber"> Christoph Huber</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Cikirikcioglu"> Mustafa Cikirikcioglu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background & objective: Mitral valve surgeries are mainly performed by median sternotomy with conventional direct atriotomy. Good exposure to the mitral valve is challenging, especially for acute pathologies, where left atrium dilation does not occur. Other atriotomies, such as transseptal or superior septal, are used as they allow better access and visualization. Peri- and postoperative outcomes of these three different left atriotomies were compared. Methods: Patients undergoing mitral valve surgery between January 2010 and December 2020 were included and divided into three groups: group 1 (conventional direct, n=115), group 2 (transseptal, n=33) and group 3 (superior septal, n=59). To improve the sampling size, all patients underwent mitral valve surgery with or without associated procedures (CABG, aortic-tricuspid surgery, Maze procedure). The study protocol was approved by SwissEthics. Results: No difference was shown for the etiology of mitral valve disease, except endocarditis, which was more frequent in group 3 (p = 0.014). Elective surgeries and isolated mitral valve surgery were more frequent in group 1 (p = 0.008, p = 0.011) and aortic clamping and cardiopulmonary bypass were shorter (p = 0.002, p<0.001). Group 3 had more emergency procedures (p = 0.011) and longer lengths of intensive care unit and hospital stay (p = 0.000, p = 0.003). There was no difference in permanent pacemaker implantation, postoperative complications and mortality between the groups. Conclusion: Mitral valve surgeries can be safely performed using those three left atriotomies. Conventional direct may lead to shorter aortic clamping and cardiopulmonary bypass times. Superior septal is mostly used for acute pathologies, and it does not increase postoperative arrhythmias and permanent pacemaker implantation. However, intensive care unit and hospital lengths of stay were found to be longer in this group. In our opinion, this outcome is more related to the pathology and type of surgery than the incision itself. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mitral%20valve%20surgery" title="Mitral valve surgery">Mitral valve surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiac%20surgery" title=" cardiac surgery"> cardiac surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=atriotomy" title=" atriotomy"> atriotomy</a>, <a href="https://publications.waset.org/abstracts/search?q=Operative%20outcomes" title=" Operative outcomes"> Operative outcomes</a> </p> <a href="https://publications.waset.org/abstracts/160482/comparison-of-peri-and-post-operative-outcomes-of-three-left-atrial-incisions-conventional-direct-transseptal-and-superior-septal-left-atriotomy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160482.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> Experimental Quantification of the Intra-Tow Resin Storage Evolution during RTM Injection </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Imbert">Mathieu Imbert</a>, <a href="https://publications.waset.org/abstracts/search?q=Sebastien%20Comas-Cardona"> Sebastien Comas-Cardona</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuelle%20Abisset-Chavanne"> Emmanuelle Abisset-Chavanne</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Prono"> David Prono</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Short cycle time Resin Transfer Molding (RTM) applications appear to be of great interest for the mass production of automotive or aeronautical lightweight structural parts. During the RTM process, the two components of a resin are mixed on-line and injected into the cavity of a mold where a fibrous preform has been placed. Injection and polymerization occur simultaneously in the preform inducing evolutions of temperature, degree of cure and viscosity that furthermore affect flow and curing. In order to adjust the processing conditions to reduce the cycle time, it is, therefore, essential to understand and quantify the physical mechanisms occurring in the part during injection. In a previous study, a dual-scale simulation tool has been developed to help determining the optimum injection parameters. This tool allows tracking finely the repartition of the resin and the evolution of its properties during reactive injections with on-line mixing. Tows and channels of the fibrous material are considered separately to deal with the consequences of the dual-scale morphology of the continuous fiber textiles. The simulation tool reproduces the unsaturated area at the flow front, generated by the tow/channel difference of permeability. Resin “storage” in the tows after saturation is also taken into account as it may significantly affect the repartition and evolution of the temperature, degree of cure and viscosity in the part during reactive injections. The aim of the current study is, thanks to experiments, to understand and quantify the “storage” evolution in the tows to adjust and validate the numerical tool. The presented study is based on four experimental repeats conducted on three different types of textiles: a unidirectional Non Crimp Fabric (NCF), a triaxial NCF and a satin weave. Model fluids, dyes and image analysis, are used to study quantitatively, the resin flow in the saturated area of the samples. Also, textiles characteristics affecting the resin “storage” evolution in the tows are analyzed. Finally, fully coupled on-line mixing reactive injections are conducted to validate the numerical model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=experimental" title="experimental">experimental</a>, <a href="https://publications.waset.org/abstracts/search?q=on-line%20mixing" title=" on-line mixing"> on-line mixing</a>, <a href="https://publications.waset.org/abstracts/search?q=high-speed%20RTM%20process" title=" high-speed RTM process"> high-speed RTM process</a>, <a href="https://publications.waset.org/abstracts/search?q=dual-scale%20flow" title=" dual-scale flow"> dual-scale flow</a> </p> <a href="https://publications.waset.org/abstracts/59210/experimental-quantification-of-the-intra-tow-resin-storage-evolution-during-rtm-injection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59210.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">165</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> N-Glycosylation in the Green Microalgae Chlamydomonas reinhardtii </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pierre-Louis%20Lucas">Pierre-Louis Lucas</a>, <a href="https://publications.waset.org/abstracts/search?q=Corinne%20Loutelier-Bourhis"> Corinne Loutelier-Bourhis</a>, <a href="https://publications.waset.org/abstracts/search?q=Narimane%20Mati-Baouche"> Narimane Mati-Baouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippe%20Chan%20Tchi-Song"> Philippe Chan Tchi-Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrice%20Lerouge"> Patrice Lerouge</a>, <a href="https://publications.waset.org/abstracts/search?q=Elodie%20Mathieu-Rivet"> Elodie Mathieu-Rivet</a>, <a href="https://publications.waset.org/abstracts/search?q=Muriel%20Bardor"> Muriel Bardor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> N-glycosylation is a post-translational modification taking place in the Endoplasmic Reticulum and the Golgi apparatus where defined glycan features are added on protein in a very specific sequence Asn-X-Thr/Ser/Cys were X can be any amino acid except proline. Because it is well-established that those N-glycans play a critical role in protein biological activity, protein half-life and that a different N-glycan structure may induce an immune response, they are very important in Biopharmaceuticals which are mainly glycoproteins bearing N-glycans. From now, most of the biopharmaceuticals are produced by mammalian cells like Chinese Hamster Ovary cells (CHO) for their N-glycosylation similar to the human, but due to the high production costs, several other species are investigated as the possible alternative system. In this purpose, the green microalgae Chlamydomonas reinhardtii was investigated as the potential production system for Biopharmaceuticals. This choice was influenced by the facts that C. reinhardtii is a well-study microalgae which is growing fast with a lot of molecular biology tools available. This organism is also producing N-glycan on its endogenous proteins. However, the analysis of the N-glycan structure of this microalgae has revealed some differences as compared to the human. Rather than in Human where the glycans are processed by key enzymes called N-acetylglucosaminyltransferase I and II (GnTI and GnTII) adding GlcNAc residue to form a GlcNAc₂Man₃GlcNAc₂ core N-glycan, C. reinhardtii lacks those two enzymes and possess a GnTI independent glycosylation pathway. Moreover, some enzymes like xylosyltransferases and methyltransferases not present in human are supposed to act on the glycans of C. reinhardtii. Furthermore, the recent structural study by mass spectrometry shows that the N-glycosylation precursor supposed to be conserved in almost all eukaryotic cells results in a linear Man₅GlcNAc₂ rather than a branched one in C. reinhardtii. In this work, we will discuss the new released MS information upon C. reinhardtii N-glycan structure and their impact on our attempt to modify the glycan in a Human manner. Two strategies will be discussed. The first one consisted in the study of Xylosyltransferase insertional mutants from the CLIP library in order to remove xyloses from the N-glycans. The second will go further in the humanization by transforming the microalgae with the exogenous gene from Toxoplasma gondii having an activity similar to GnTI and GnTII with the aim to synthesize GlcNAc₂Man₃GlcNAc₂ in C. reinhardtii. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chlamydomonas%20reinhardtii" title="Chlamydomonas reinhardtii">Chlamydomonas reinhardtii</a>, <a href="https://publications.waset.org/abstracts/search?q=N-glycosylation" title=" N-glycosylation"> N-glycosylation</a>, <a href="https://publications.waset.org/abstracts/search?q=glycosyltransferase" title=" glycosyltransferase"> glycosyltransferase</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20spectrometry" title=" mass spectrometry"> mass spectrometry</a>, <a href="https://publications.waset.org/abstracts/search?q=humanization" title=" humanization"> humanization</a> </p> <a href="https://publications.waset.org/abstracts/88988/n-glycosylation-in-the-green-microalgae-chlamydomonas-reinhardtii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88988.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Occupational Exposure and Contamination to Antineoplastic Drugs of Healthcare Professionals in Mauritania</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Villa">Antoine Villa</a>, <a href="https://publications.waset.org/abstracts/search?q=Moustapha%20Mohamedou"> Moustapha Mohamedou</a>, <a href="https://publications.waset.org/abstracts/search?q=Florence%20Pilliere"> Florence Pilliere</a>, <a href="https://publications.waset.org/abstracts/search?q=Catherine%20Verdun-Esquer"> Catherine Verdun-Esquer</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Molimard"> Mathieu Molimard</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Sidatt%20Cheikh%20El%20Moustaph"> Mohamed Sidatt Cheikh El Moustaph</a>, <a href="https://publications.waset.org/abstracts/search?q=Mireille%20Canal-Raffin"> Mireille Canal-Raffin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Context: In Mauritania, the activity of the National Center of Oncology (NCO) has steadily risen leading to an increase in the handling of antineoplastic drugs (AD) by healthcare professionals. In this context, the AD contamination of those professionals is a major concern for occupational physicians. It has been evaluated using biological monitoring of occupational exposure (BMOE). Methods: The intervention took place in 2015, in 2 care units, and evaluated nurses preparing and/or infusing AD and agents in charge of hygiene. Participants provided a single urine sample, at the end of the week, at the end of their shift. Five molecules were sought using specific high sensitivity methods (UHPLC-MS/MS) with very low limits of quantification (LOQ) (cyclophosphamide (CP), Ifosfamide (IF), methotrexate (MTX): 2.5ng/L; doxorubicin (Doxo): 10ng/L; α-fluoro-β-alanine (FBAL, 5-FU metabolite): 20ng/L). A healthcare worker was considered as 'contaminated' when an AD was detected at a urine concentration equal to or greater than the LOQ of the analytical method or at trace concentration. Results: Twelve persons participated (6 nurses, 6 agents in charge of hygiene). Twelve urine samples were collected and analyzed. The percentage of contamination was 66.6% for all participants (n=8/12), 100% for nurses (6/6) and 33% for agents in charge of hygiene (2/6). In 62.5% (n=5/8) of the contaminated workers, two to four of the AD were detected in the urine. CP was found in the urine of all contaminated workers. FBAL was found in four, MTX in three and Doxo in one. Only IF was not detected. Urinary concentrations (all drugs combined) ranged from 3 to 844 ng/L for nurses and from 3 to 44 ng/L for agents in charge of hygiene. The median urinary concentrations were 87 ng/L, 15.1 ng/L and 4.4 ng/L for FBAL, CP and MTX, respectively. The Doxo urinary concentration was found 218ng/L. Discussion: There is no current biological exposure index for the interpretation of AD contamination. The contamination of these healthcare professionals is therefore established by the detection of one or more AD in urine. These urinary contaminations are higher than the LOQ of the analytical methods, which must be as low as possible. Given the danger of AD, the implementation of corrective measures is essential for the staff. Biological monitoring of occupational exposure is the most reliable process to identify groups at risk, tracing insufficiently controlled exposures and as an alarm signal. These results show the necessity to educate professionals about the risks of handling AD and/or to care for treated patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antineoplastic%20drugs" title="antineoplastic drugs">antineoplastic drugs</a>, <a href="https://publications.waset.org/abstracts/search?q=Mauritania" title=" Mauritania"> Mauritania</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20monitoring%20of%20occupational%20exposure" title=" biological monitoring of occupational exposure"> biological monitoring of occupational exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=contamination" title=" contamination"> contamination</a> </p> <a href="https://publications.waset.org/abstracts/95465/occupational-exposure-and-contamination-to-antineoplastic-drugs-of-healthcare-professionals-in-mauritania" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95465.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">316</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> Traumatic Brain Injury in Cameroon: A Prospective Observational Study in a Level 1 Trauma Centre</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Franklin%20Chu%20Buh">Franklin Chu Buh</a>, <a href="https://publications.waset.org/abstracts/search?q=Irene%20Ule%20Ngole%20Sumbele"> Irene Ule Ngole Sumbele</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20I.%20R.%20Maas"> Andrew I.

The objective of this study was to define the features and outcomes of TBI patients seen over a 1-year period in a level-I trauma center in Cameroon. Methods: Data on demographics, causes, injury mechanisms, clinical aspects, and discharge status were prospectively collected over a period of 12 months. The Glasgow Outcome Scale-Extended (GOSE) and the Quality of Life Questionnaire after Brain Injury (QoLIBRI) were used to evaluate outcomes 6-months after TBI. Categorical variables were described as frequencies and percentages. Comparisons between 2 categorical variables were done using Pearson's Chi-square test or Fisher's exact test. Results: A total of 160 TBI patients participated in the study. The age group 15-45 years (78%; 125) was most represented. Males were more affected (90%; 144). Low educational level was recorded in 122 (76%) cases. Road traffic incidents (RTI) were the main cause of TBI (85%), with professional bike riders being frequently involved (27%, 43/160). Assaults (7.5%) and falls (2.5%) represent the second and third most common causes of TBI in Cameroon, respectively. Only 15 patients were transported to the hospital by ambulance, and 14 of these were from a referring hospital. CT-imaging was performed in 78% (125/160) of cases intracranial traumatic abnormality was identified in 77/125 (64%) cases. Financial constraints were the main reason for not performing a CT scan on 35 patients. A total of 46 (33%) patients were discharged against medical advice (DAMA) due to financial constraints. Mortality was 14% (22/160) but disproportionately high in patients with severe TBI (46%). DAMA had poor outcomes with QoLIBRI. Only 4 patients received post-injury physiotherapy services. Conclusion: TBI in Cameroon mainly results from RTIs and commonly affects young adult males, and low educational or socioeconomic status and commercial bike riding appear to be predisposing factors. Lack of pre-hospital care, financial constraints limiting both CT-scanning and medical care, and lack of acute physiotherapy services likely influenced care and outcomes adversely. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=characteristics" title="characteristics">characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=traumatic%20brain%20injury" title=" traumatic brain injury"> traumatic brain injury</a>, <a href="https://publications.waset.org/abstracts/search?q=outcome" title=" outcome"> outcome</a>, <a href="https://publications.waset.org/abstracts/search?q=disparities%20in%20care" title=" disparities in care"> disparities in care</a>, <a href="https://publications.waset.org/abstracts/search?q=prospective%20study" title=" prospective study"> prospective study</a> </p> <a href="https://publications.waset.org/abstracts/156536/traumatic-brain-injury-in-cameroon-a-prospective-observational-study-in-a-level-1-trauma-centre" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156536.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> A webGIS Methodology to Support Sediments Management in Wallonia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nathalie%20Stephenne">Nathalie Stephenne</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Veschkens"> Mathieu Veschkens</a>, <a href="https://publications.waset.org/abstracts/search?q=St%C3%A9phane%20Palm"> Stéphane Palm</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Charlemagne"> Christophe Charlemagne</a>, <a href="https://publications.waset.org/abstracts/search?q=Jacques%20Defoux"> Jacques Defoux</a> </p> <p class="card-text"><strong>Abstract:</strong></p> According to Europe’s first River basin Management Plans (RBMPs), 56% of European rivers failed to achieve the good status targets of the Water Framework Directive WFD. In Central European countries such as Belgium, even more than 80% of rivers failed to achieve the WFD quality targets. Although the RBMP’s should reduce the stressors and improve water body status, their potential to address multiple stress situations is limited due to insufficient knowledge on combined effects, multi-stress, prioritization of measures, impact on ecology and implementation effects. This paper describes a webGis prototype developed for the Walloon administration to improve the communication and the management of sediment dredging actions carried out in rivers and lakes in the frame of RBMPs. A large number of stakeholders are involved in the management of rivers and lakes in Wallonia. They are in charge of technical aspects (client and dredging operators, organizations involved in the treatment of waste…), management (managers involved in WFD implementation at communal, provincial or regional level) or policy making (people responsible for policy compliance or legislation revision). These different kinds of stakeholders need different information and data to cover their duties but have to interact closely at different levels. Moreover, information has to be shared between them to improve the management quality of dredging operations within the ecological system. In the Walloon legislation, leveling dredged sediments on banks requires an official authorization from the administration. This request refers to spatial information such as the official land use map, the cadastral map, the distance to potential pollution sources. The production of a collective geodatabase can facilitate the management of these authorizations from both sides. The proposed internet system integrates documents, data input, integration of data from disparate sources, map representation, database queries, analysis of monitoring data, presentation of results and cartographic visualization. A prototype of web application using the API geoviewer chosen by the Geomatic department of the SPW has been developed and discussed with some potential users to facilitate the communication, the management and the quality of the data. The structure of the paper states the why, what, who and how of this communication tool. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sediments" title="sediments">sediments</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20application" title=" web application"> web application</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=rivers%20management" title=" rivers management"> rivers management</a> </p> <a href="https://publications.waset.org/abstracts/29174/a-webgis-methodology-to-support-sediments-management-in-wallonia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29174.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">405</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> High Resolution Satellite Imagery and Lidar Data for Object-Based Tree Species Classification in Quebec, Canada</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bilel%20Chalghaf">Bilel Chalghaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Varin"> Mathieu Varin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Forest characterization in Quebec, Canada, is usually assessed based on photo-interpretation at the stand level. For species identification, this often results in a lack of precision. Very high spatial resolution imagery, such as DigitalGlobe, and Light Detection and Ranging (LiDAR), have the potential to overcome the limitations of aerial imagery. To date, few studies have used that data to map a large number of species at the tree level using machine learning techniques. The main objective of this study is to map 11 individual high tree species ( > 17m) at the tree level using an object-based approach in the broadleaf forest of Kenauk Nature, Quebec. For the individual tree crown segmentation, three canopy-height models (CHMs) from LiDAR data were assessed: 1) the original, 2) a filtered, and 3) a corrected model. The corrected CHM gave the best accuracy and was then coupled with imagery to refine tree species crown identification. When compared with photo-interpretation, 90% of the objects represented a single species. For modeling, 313 variables were derived from 16-band WorldView-3 imagery and LiDAR data, using radiance, reflectance, pixel, and object-based calculation techniques. Variable selection procedures were employed to reduce their number from 313 to 16, using only 11 bands to aid reproducibility. For classification, a global approach using all 11 species was compared to a semi-hierarchical hybrid classification approach at two levels: (1) tree type (broadleaf/conifer) and (2) individual broadleaf (five) and conifer (six) species. Five different model techniques were used: (1) support vector machine (SVM), (2) classification and regression tree (CART), (3) random forest (RF), (4) k-nearest neighbors (k-NN), and (5) linear discriminant analysis (LDA). Each model was tuned separately for all approaches and levels. For the global approach, the best model was the SVM using eight variables (overall accuracy (OA): 80%, Kappa: 0.77). With the semi-hierarchical hybrid approach, at the tree type level, the best model was the k-NN using six variables (OA: 100% and Kappa: 1.00). At the level of identifying broadleaf and conifer species, the best model was the SVM, with OA of 80% and 97% and Kappa values of 0.74 and 0.97, respectively, using seven variables for both models. This paper demonstrates that a hybrid classification approach gives better results and that using 16-band WorldView-3 with LiDAR data leads to more precise predictions for tree segmentation and classification, especially when the number of tree species is large. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tree%20species" title="tree species">tree species</a>, <a href="https://publications.waset.org/abstracts/search?q=object-based" title=" object-based"> object-based</a>, <a href="https://publications.waset.org/abstracts/search?q=classification" title=" classification"> classification</a>, <a href="https://publications.waset.org/abstracts/search?q=multispectral" title=" multispectral"> multispectral</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=WorldView-3" title=" WorldView-3"> WorldView-3</a>, <a href="https://publications.waset.org/abstracts/search?q=LiDAR" title=" LiDAR"> LiDAR</a> </p> <a href="https://publications.waset.org/abstracts/119023/high-resolution-satellite-imagery-and-lidar-data-for-object-based-tree-species-classification-in-quebec-canada" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119023.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">134</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Integrating Qualitative and Behavioural Insights to Increase the Take-Up of an Education Savings Program for Low Income Canadians</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Audet">Mathieu Audet</a>, <a href="https://publications.waset.org/abstracts/search?q=Monica%20Soliman"> Monica Soliman</a>, <a href="https://publications.waset.org/abstracts/search?q=Emilie%20Eve%20Gravel"> Emilie Eve Gravel</a>, <a href="https://publications.waset.org/abstracts/search?q=Rebecca%20Friesdorf"> Rebecca Friesdorf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Access to higher education is critical for reducing social inequalities. The Canada Learning Bond (CLB) is a government savings incentive aimed at increasing higher education access for children of low income families by providing money toward a Registered Education Savings Plan. To better understand the educational and financial decision-making of low income families, Employment Social Development Canada conducted qualitative fieldwork with eligible parents and children, teachers, and community organizations promoting the Bond. Insights from this fieldwork were then used to develop letters to better target the needs and experiences of eligible families. In the present study, we conducted a randomized controlled trial with children ages 12 to 13, the oldest cohort of eligible children, to test the effectiveness of the new letters. Parents or caregivers of 150,088 eligible children were assigned to one of five letter conditions promoting the Bond or to a control condition that did not receive a letter. The letter conditions were: (a) the standard letter from past outreach, (b) a letter presenting the exact amount the child was eligible to receive, enhancing the salience of benefits, (c) a letter with a social norm, (d) a letter with an image emphasizing the feasibility of higher education by presenting the diversity of options (i.e., college, trade schools, apprenticeships) – many participants interviewed viewed that university was unfeasible, and (e) a letter minimizing references to 'saving' (i.e., not framing the Bond explicitly as a savings incentive) – a concept that did not resonate with low income families who felt they could not afford to save. The exact amount was also presented in letters (c) through (e). The letter minimizing references to 'saving' and presenting the exact amount had the highest net take-up rate at 6.6%, compared to 3.5% for the standard letter group. Furthermore, this trial’s BI-informed letters showed the largest impact on take-up so far, with a net take-up of 5.7% compared to 3.0% and 3.9% in the first two trials. This research highlights the value of mixed-method approaches combining qualitative and behavioural insights methods for developing context-sensitive interventions for social programs. By gaining a deeper understanding of the needs and experiences of program users through qualitative fieldwork, and then integrating these insights into behaviourally informed communications, we were able to increase take-up of an education savings program, which may ultimately improve access to higher education in children of low income families. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=access%20to%20higher%20education" title="access to higher education">access to higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=behavioral%20insights" title=" behavioral insights"> behavioral insights</a>, <a href="https://publications.waset.org/abstracts/search?q=government" title=" government"> government</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation" title=" innovation"> innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed-methods" title=" mixed-methods"> mixed-methods</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20programs" title=" social programs"> social programs</a> </p> <a href="https://publications.waset.org/abstracts/102288/integrating-qualitative-and-behavioural-insights-to-increase-the-take-up-of-an-education-savings-program-for-low-income-canadians" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102288.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">124</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Adaptive Environmental Control System Strategy for Cabin Air Quality in Commercial Aircrafts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paolo%20Grasso">Paolo Grasso</a>, <a href="https://publications.waset.org/abstracts/search?q=Sai%20Kalyan%20Yelike"> Sai Kalyan Yelike</a>, <a href="https://publications.waset.org/abstracts/search?q=Federico%20Benzi"> Federico Benzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Le%20Cam"> Mathieu Le Cam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The cabin air quality (CAQ) in commercial aircraft is of prime interest, especially in the context of the COVID-19 pandemic. Current Environmental Control Systems (ECS) rely on a prescribed fresh airflow per passenger to dilute contaminants. An adaptive ECS strategy is proposed, leveraging air sensing and filtration technologies to ensure a better CAQ. This paper investigates the CAQ level achieved in commercial aircraft’s cabin during various flight scenarios. The modeling and simulation analysis is performed in a Modelica-based environment describing the dynamic behavior of the system. The model includes the following three main systems: cabin, recirculation loop and air-conditioning pack. The cabin model evaluates the thermo-hygrometric conditions and the air quality in the cabin depending on the number of passengers and crew members, the outdoor conditions and the conditions of the air supplied to the cabin. The recirculation loop includes models of the recirculation fan, ordinary and novel filtration technology, mixing chamber and outflow valve. The air-conditioning pack includes models of heat exchangers and turbomachinery needed to condition the hot pressurized air bled from the engine, as well as selected contaminants originated from the outside or bled from the engine. Different ventilation control strategies are modeled and simulated. Currently, a limited understanding of contaminant concentrations in the cabin and the lack of standardized and systematic methods to collect and record data constitute a challenge in establishing a causal relationship between CAQ and passengers' comfort. As a result, contaminants are neither measured nor filtered during flight, and the current sub-optimal way to avoid their accumulation is their dilution with the fresh air flow. However, the use of a prescribed amount of fresh air comes with a cost, making the ECS the most energy-demanding non-propulsive system within an aircraft. In such a context, this study shows that an ECS based on a reduced and adaptive fresh air flow, and relying on air sensing and filtration technologies, provides promising results in terms of CAQ control. The comparative simulation results demonstrate that the proposed adaptive ECS brings substantial improvements to the CAQ in terms of both controlling the asymptotic values of the concentration of the contaminant and in mitigating hazardous scenarios, such as fume events. Original architectures allowing for adaptive control of the inlet air flow rate based on monitored CAQ will change the requirements for filtration systems and redefine the ECS operation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cabin%20air%20quality" title="cabin air quality">cabin air quality</a>, <a href="https://publications.waset.org/abstracts/search?q=commercial%20aircraft" title=" commercial aircraft"> commercial aircraft</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20control%20system" title=" environmental control system"> environmental control system</a>, <a href="https://publications.waset.org/abstracts/search?q=ventilation" title=" ventilation"> ventilation</a> </p> <a href="https://publications.waset.org/abstracts/152286/adaptive-environmental-control-system-strategy-for-cabin-air-quality-in-commercial-aircrafts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152286.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">101</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Calibration of Residential Buildings Energy Simulations Using Real Data from an Extensive in situ Sensor Network – A Study of Energy Performance Gap</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Bourdeau">Mathieu Bourdeau</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippe%20Basset"> Philippe Basset</a>, <a href="https://publications.waset.org/abstracts/search?q=Julien%20Waeytens"> Julien Waeytens</a>, <a href="https://publications.waset.org/abstracts/search?q=Elyes%20Nefzaoui"> Elyes Nefzaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As residential buildings account for a third of the overall energy consumption and greenhouse gas emissions in Europe, building energy modeling is an essential tool to reach energy efficiency goals. In the energy modeling process, calibration is a mandatory step to obtain accurate and reliable energy simulations. Nevertheless, the comparison between simulation results and the actual building energy behavior often highlights a significant performance gap. The literature discusses different origins of energy performance gaps, from building design to building operation. Then, building operation description in energy models, especially energy usages and users’ behavior, plays an important role in the reliability of simulations but is also the most accessible target for post-occupancy energy management and optimization. Therefore, the present study aims to discuss results on the calibration ofresidential building energy models using real operation data. Data are collected through a sensor network of more than 180 sensors and advanced energy meters deployed in three collective residential buildings undergoing major retrofit actions. The sensor network is implemented at building scale and in an eight-apartment sample. Data are collected for over one year and half and coverbuilding energy behavior – thermal and electricity, indoor environment, inhabitants’ comfort, occupancy, occupants behavior and energy uses, and local weather. Building energy simulations are performed using a physics-based building energy modeling software (Pleaides software), where the buildings’features are implemented according to the buildingsthermal regulation code compliance study and the retrofit project technical files. Sensitivity analyses are performed to highlight the most energy-driving building features regarding each end-use. These features are then compared with the collected post-occupancy data. Energy-driving features are progressively replaced with field data for a step-by-step calibration of the energy model. Results of this study provide an analysis of energy performance gap on an existing residential case study under deep retrofit actions. It highlights the impact of the different building features on the energy behavior and the performance gap in this context, such as temperature setpoints, indoor occupancy, the building envelopeproperties but also domestic hot water usage or heat gains from electric appliances. The benefits of inputting field data from an extensive instrumentation campaign instead of standardized scenarios are also described. Finally, the exhaustive instrumentation solution provides useful insights on the needs, advantages, and shortcomings of the implemented sensor network for its replicability on a larger scale and for different use cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calibration" title="calibration">calibration</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20energy%20modeling" title=" building energy modeling"> building energy modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20gap" title=" performance gap"> performance gap</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor%20network" title=" sensor network"> sensor network</a> </p> <a href="https://publications.waset.org/abstracts/145513/calibration-of-residential-buildings-energy-simulations-using-real-data-from-an-extensive-in-situ-sensor-network-a-study-of-energy-performance-gap" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145513.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Tool Development for Assessing Antineoplastic Drugs Surface Contamination in Healthcare Services and Other Workplaces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Atge">Benoit Atge</a>, <a href="https://publications.waset.org/abstracts/search?q=Alice%20Dhersin"> Alice Dhersin</a>, <a href="https://publications.waset.org/abstracts/search?q=Oscar%20Da%20Silva%20Cacao"> Oscar Da Silva Cacao</a>, <a href="https://publications.waset.org/abstracts/search?q=Beatrice%20Martinez"> Beatrice Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominique%20Ducint"> Dominique Ducint</a>, <a href="https://publications.waset.org/abstracts/search?q=Catherine%20Verdun-Esquer"> Catherine Verdun-Esquer</a>, <a href="https://publications.waset.org/abstracts/search?q=Isabelle%20Baldi"> Isabelle Baldi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Molimard"> Mathieu Molimard</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Villa"> Antoine Villa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mireille%20Canal-Raffin"> Mireille Canal-Raffin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Healthcare workers' exposure to antineoplastic drugs (AD) is a burning issue for occupational medicine practitioners. Biological monitoring of occupational exposure (BMOE) is an essential tool for assessing AD contamination of healthcare workers. In addition to BMOE, surface sampling is a useful tool in order to understand how workers get contaminated, to identify sources of environmental contamination, to verify the effectiveness of surface decontamination way and to ensure monitoring of these surfaces. The objective of this work was to develop a complete tool including a kit for surface sampling and a quantification analytical method for AD traces detection. The development was realized with the three following criteria: the kit capacity to sample in every professional environment (healthcare services, veterinaries, etc.), the detection of very low AD traces with a validated analytical method and the easiness of the sampling kit use regardless of the person in charge of sampling. Material and method: AD mostly used in term of quantity and frequency have been identified by an analysis of the literature and consumptions of different hospitals, veterinary services, and home care settings. The kind of adsorbent device, surface moistening solution and mix of solvents for the extraction of AD from the adsorbent device have been tested for a maximal yield. The AD quantification was achieved by an ultra high-performance liquid chromatography method coupled with tandem mass spectrometry (UHPLC-MS/MS). Results: With their high frequencies of use and their good reflect of the diverse activities through healthcare, 15 AD (cyclophosphamide, ifosfamide, doxorubicin, daunorubicin, epirubicin, 5-FU, dacarbazin, etoposide, pemetrexed, vincristine, cytarabine, methothrexate, paclitaxel, gemcitabine, mitomycin C) were selected. The analytical method was optimized and adapted to obtain high sensitivity with very low limits of quantification (25 to 5000ng/mL), equivalent or lowest that those previously published (for 13/15 AD). The sampling kit is easy to use, provided with a didactic support (online video and protocol paper). It showed its effectiveness without inter-individual variation (n=5/person; n= 5 persons; p=0,85; ANOVA) regardless of the person in charge of sampling. Conclusion: This validated tool (sampling kit + analytical method) is very sensitive, easy to use and very didactic in order to control the chemical risk brought by AD. Moreover, BMOE permits a focal prevention. Used in routine, this tool is available for every intervention of occupational health. <p class="card-text"><strong>Keywords:</strong> <a
