This NKT cell subset expressed CD38 but not CD4, produced IFN-γ, but not IL-17, IL-4 or IL-13, and inhibited the development of airway hyperreactivity (AHR) through contact-dependent suppressive activity against helper CD4 T cells. The NKT subset expanded in the lungs of neonatal mice after infection with influenza, but also after treatment of neonatal mice with a Th1-biasing α-GalCer glycolipid analogue, Nu-α-GalCer. These results suggest that early/neonatal exposure to infection or to antigenic challenge can affect subsequent lung immunity by altering the profile of cells residing in the lung and that some subsets of NKT cells can have direct inhibitory activity against CD4+ T cells in allergic asthma. Importantly, our results also suggest a potential therapy for young children that might provide protection against the development of asthma. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NKT%20subset" title="NKT subset">NKT subset</a>, <a href="https://publications.waset.org/abstracts/search?q=asthma" title=" asthma"> asthma</a>, <a href="https://publications.waset.org/abstracts/search?q=airway%20hyperreactivity" title=" airway hyperreactivity"> airway hyperreactivity</a>, <a href="https://publications.waset.org/abstracts/search?q=hygiene%20hypothesis" title=" hygiene hypothesis"> hygiene hypothesis</a>, <a href="https://publications.waset.org/abstracts/search?q=influenza" title=" influenza"> influenza</a> </p> <a href="https://publications.waset.org/abstracts/80053/a-natural-killer-t-cell-subset-that-protects-against-airway-hyperreactivity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80053.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">240</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">87</span> A Serious Game to Upgrade the Learning of Organizational Skills in Nursing Schools</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Landi">Benoit Landi</a>, <a href="https://publications.waset.org/abstracts/search?q=Herv%C3%A9%20Pingaud"> Hervé Pingaud</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Benoit%20Culie"> Jean-Benoit Culie</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Galaup"> Michel Galaup</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Serious games have been widely disseminated in the field of digital learning. They have proved their utility in improving skills through virtual environments that simulate the field where new competencies have to be improved and assessed. This paper describes how we created CLONE, a serious game whose purpose is to help nurses create an efficient work plan in a hospital care unit. In CLONE, the number of patients to take care of is similar to the reality of their job, going far beyond what is currently practiced in nurse school classrooms. This similarity with the operational field increases proportionally the number of activities to be scheduled. Moreover, very often, the team of nurses is composed of regular nurses and nurse assistants that must share the work with respect to the regulatory obligations. Therefore, on the one hand, building a short-term planning is a complex task with a large amount of data to deal with, and on the other, good clinical practices have to be systematically applied. We present how reference planning has been defined by addressing an optimization problem formulation using the expertise of teachers. This formulation ensures the gameplay feasibility for the scenario that has been produced and enhanced throughout the game design process. It was also crucial to steer a player toward a specific gaming strategy. As one of our most important learning outcomes is a clear understanding of the workload concept, its factual calculation for each caregiver along time and its inclusion in the nurse reasoning during planning elaboration are focal points. We will demonstrate how to modify the game scenario to create a digital environment in which these somewhat abstract principles can be understood and applied. Finally, we give input on an experience we had on a pilot of a thousand undergraduate nursing students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=care%20planning" title="care planning">care planning</a>, <a href="https://publications.waset.org/abstracts/search?q=workload" title=" workload"> workload</a>, <a href="https://publications.waset.org/abstracts/search?q=game%20design" title=" game design"> game design</a>, <a href="https://publications.waset.org/abstracts/search?q=hospital%20nurse" title=" hospital nurse"> hospital nurse</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20skills" title=" organizational skills"> organizational skills</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20learning" title=" digital learning"> digital learning</a>, <a href="https://publications.waset.org/abstracts/search?q=serious%20game" title=" serious game"> serious game</a> </p> <a href="https://publications.waset.org/abstracts/142315/a-serious-game-to-upgrade-the-learning-of-organizational-skills-in-nursing-schools" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142315.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">191</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">86</span> Effect of Ion Irradiation on the Microstructure and Properties of Chromium Coatings on Zircaloy-4 Substrate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexia%20Wu">Alexia Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Joel%20Ribis"> Joel Ribis</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Christophe%20Brachet"> Jean-Christophe Brachet</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Clouet"> Emmanuel Clouet</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Arnal"> Benoit Arnal</a>, <a href="https://publications.waset.org/abstracts/search?q=Elodie%20Rouesne"> Elodie Rouesne</a>, <a href="https://publications.waset.org/abstracts/search?q=St%C3%A9phane%20Urvoy"> Stéphane Urvoy</a>, <a href="https://publications.waset.org/abstracts/search?q=Justine%20Roubaud"> Justine Roubaud</a>, <a href="https://publications.waset.org/abstracts/search?q=Yves%20Serruys"> Yves Serruys</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederic%20Lepretre"> Frederic Lepretre</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To enhance the safety of Light Water Reactor, accident tolerant fuel (ATF) claddings materials are under development. In the framework of CEA-AREVA-EDF collaborative program on ATF cladding materials, CEA has engaged specific studies on chromium coated zirconium alloys. Especially for Loss-of-Coolant-Accident situations, chromium coated claddings have shown some additional 'coping' time before achieving full embrittlement of the oxidized cladding, when compared to uncoated references – both tested in steam environment up to 1300°C. Nevertheless, the behavior of chromium coatings and the stability of the Zr-Cr interface under neutron irradiation remain unknown. Two main points are addressed: 1. Bulk Cr behavior under irradiation: Due to its BCC crystallographic structure, Cr is prone to Ductile-to-Brittle-Transition at quite high temperature. Irradiation could be responsible for a significant additional DBTT shift towards higher temperatures. 2. Zircaloy/Cr interface behavior under irradiation: Preliminary TEM examinations of un-irradiated samples revealed a singular Zircaloy-4/Cr interface with nanometric intermetallic phase layers. Such particular interfaces highlight questions of how they would behave under irradiation - intermetallic zirconium phases are known to be more or less stable under irradiations. Another concern is a potential enhancement of chromium diffusion into the zirconium-alpha based substrate. The purpose of this study is then to determine the behavior of such coatings after ion irradiations, as a surrogate to neutron irradiation. Ion irradiations were performed at the Jannus-Saclay facility (France). 20 MeV Kr8+ ions at 400°C with a flux of 2.8x1011 ions.cm-2.s-1 were used to irradiate chromium coatings of 1-2 µm thick on Zircaloy-4 sheets substrate. At the interface, the calculated damage is close to 10 dpa (SRIM, Quick Calculation Damage mode). Thin foil samples were prepared with FIB for both as-received and irradiated coated samples. Transmission Electron Microscopy (TEM) and in-situ tensile tests in a Scanning Electron Microscope are being used to characterize the un-irradiated and irradiated materials. High Resolution TEM highlights a great complexity of the interface before irradiation since it is formed of an alternation of intermetallic phases – C14 and C15. The interfaces formed by these intermetallic phases with chromium and zirconium show semi-coherency. Chemical analysis performed before irradiation shows some iron enrichment at the interface. The chromium coating bulk microstructures and properties are also studied before and after irradiation. On-going in-situ tensile tests focus on the capacity of chromium coatings to sustain some plastic deformation when tested up to 350°C. The stability of the Cr/Zr interface is shown after ion irradiation up to 10 dpa. This observation constitutes the first result after irradiation on these new coated claddings materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accident%20tolerant%20fuel" title="accident tolerant fuel">accident tolerant fuel</a>, <a href="https://publications.waset.org/abstracts/search?q=HRTEM" title=" HRTEM"> HRTEM</a>, <a href="https://publications.waset.org/abstracts/search?q=interface" title=" interface"> interface</a>, <a href="https://publications.waset.org/abstracts/search?q=ion-irradiation" title=" ion-irradiation"> ion-irradiation</a> </p> <a href="https://publications.waset.org/abstracts/55460/effect-of-ion-irradiation-on-the-microstructure-and-properties-of-chromium-coatings-on-zircaloy-4-substrate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55460.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">363</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">85</span> A Political-Economic Analysis of Next Generation EU Recovery Fund</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fernando%20Mart%C3%ADn-Espejo">Fernando Martín-Espejo</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Crombez"> Christophe Crombez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a political-economic analysis of the reforms introduced during the coronavirus crisis at the EU level with a special emphasis on the recovery fund Next Generation EU (NGEU).

The coating also demonstrates excellent self-cleaning properties, which makes it a promising candidate for commercial use. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coatings" title="coatings">coatings</a>, <a href="https://publications.waset.org/abstracts/search?q=durability" title=" durability"> durability</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrophobicity" title=" hydrophobicity"> hydrophobicity</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20polysilazane" title=" organic polysilazane"> organic polysilazane</a>, <a href="https://publications.waset.org/abstracts/search?q=self-cleaning" title=" self-cleaning"> self-cleaning</a>, <a href="https://publications.waset.org/abstracts/search?q=transparence" title=" transparence"> transparence</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc%20oxide%20nanoparticles" title=" zinc oxide nanoparticles"> zinc oxide nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/124131/highly-transparent-hydrophobic-and-self-cleaning-zno-durazane-based-hybrid-organic-inorganic-coatings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124131.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">170</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">81</span> Boosting Crime Scene Investigations Capabilities through Crime Script Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Leclerc">Benoit Leclerc</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The concept of scripts and the role that crime scripts has been playing in criminology during the last decade is reviewed. Particularly illuminating is the potential use of scripts not only to understand and disrupt offender scripts (e.g., commonly referred as crime scripts) but to capture victim and guardian scripts to increase the likelihood of preventing crime. Similarly, the concept of scripts is applied to forensic science – another field that can benefit from script analysis. First, similar to guardian scripts, script analysis can illuminate the process of completing crime scene investigations for those who investigate (crime scene investigators or other professionals involved in crime scene investigations), and as a result, provide a range of intervention-points to improve the success of these investigations. Second, script analysis can also provide valuable information on offenders’ crime-commission processes for crime scene investigators and highlight a number of ‘contact points’ that could be targeted during investigations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crime%20scripts" title="crime scripts">crime scripts</a>, <a href="https://publications.waset.org/abstracts/search?q=crime%20scene%20investigation" title=" crime scene investigation"> crime scene investigation</a>, <a href="https://publications.waset.org/abstracts/search?q=script%20analysis" title=" script analysis"> script analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=situational%20crime%20prevention" title=" situational crime prevention"> situational crime prevention</a> </p> <a href="https://publications.waset.org/abstracts/68702/boosting-crime-scene-investigations-capabilities-through-crime-script-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68702.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">275</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">80</span> Magnetoelectric Effect in Polyvinylidene Fluoride Beta Phase Thin Films</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Belouadah%20Rabah">Belouadah Rabah</a>, <a href="https://publications.waset.org/abstracts/search?q=Guyomar%20Daneil"> Guyomar Daneil</a>, <a href="https://publications.waset.org/abstracts/search?q=Guiffard%20Benoit"> Guiffard Benoit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The magnetoelectric (ME) materials has dielectric polarization induced by the magnetic field or induced magnetization under an electric field.

When it comes to building technology, it is more important to test the products for their efficiency. The test rig in the HIL simulator may contribute to some uncertainties on measured efficiency. The uncertainties include physical uncertainties and scenario-based uncertainties. In this paper, a simple uncertainty analysis framework for an HIL setup is shown considering only the physical uncertainties. The entire modeling of the HIL setup is done in Dymola. The uncertain sources are considered based on available knowledge of the components and also on expert knowledge. For the propagation of uncertainty, Monte Carlo Simulation is used since it is the most reliable and easy to use. In this article it is shown how an HIL setup can be modeled and how uncertainty propagation can be performed on it. Such an approach is not common in building energy analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20in%20buildings" title="energy in buildings">energy in buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=hardware%20in%20loop%20testing" title=" hardware in loop testing"> hardware in loop testing</a>, <a href="https://publications.waset.org/abstracts/search?q=modelica%20modelling" title=" modelica modelling"> modelica modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo%20simulation" title=" Monte Carlo simulation"> Monte Carlo simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty%20propagation" title=" uncertainty propagation "> uncertainty propagation </a> </p> <a href="https://publications.waset.org/abstracts/129384/uncertainty-analysis-of-a-hardware-in-loop-setup-for-testing-products-related-to-building-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129384.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">137</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">77</span> Synthesis and Characterization of Fluorine-Free, Hydrophobic and Highly Transparent Coatings </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abderrahmane%20Hamdi">Abderrahmane Hamdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Julie%20Chalon"> Julie Chalon</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Dodin"> Benoit Dodin</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippe%20Champagne"> Philippe Champagne</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research work concerns the synthesis of hydrophobic and self-cleaning coatings as an alternative to fluorine-based coatings used on glass. The developed, highly transparent coatings are produced by a chemical route (sol-gel method) using two silica-based precursors, hexamethyldisilazane and tetraethoxysilane (HMDS/TEOS). The addition of zinc oxide nanoparticles (ZnO NPs) within the gel provides a photocatalytic property to the final coating. The prepared gels were deposited on glass slides using different methods. The properties of the coatings were characterized by optical microscopy, scanning electron microscopy, UV-VIS-NIR spectrophotometer, and water contact angle method. The results show that the obtained coatings are homogeneous and have a hydrophobic character. In particular, after thermal treatment, the HMDS/TEOS@ZnO charged gel deposited on glass constitutes a coating capable of degrading methylene blue (MB) under UV irradiation. Optical transmission reaches more than 90% in most of the visible light spectrum. Synthetized coatings have also demonstrated their mechanical durability and self-cleaning ability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coating" title="coating">coating</a>, <a href="https://publications.waset.org/abstracts/search?q=durability" title=" durability"> durability</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrophobicity" title=" hydrophobicity"> hydrophobicity</a>, <a href="https://publications.waset.org/abstracts/search?q=sol-gel" title=" sol-gel"> sol-gel</a>, <a href="https://publications.waset.org/abstracts/search?q=self-cleaning" title=" self-cleaning"> self-cleaning</a>, <a href="https://publications.waset.org/abstracts/search?q=transparence" title=" transparence"> transparence</a> </p> <a href="https://publications.waset.org/abstracts/122907/synthesis-and-characterization-of-fluorine-free-hydrophobic-and-highly-transparent-coatings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122907.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">162</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">76</span> Shock and Particle Velocity Determination from Microwave Interrogation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Rougier">Benoit Rougier</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandre%20Lefrancois"> Alexandre Lefrancois</a>, <a href="https://publications.waset.org/abstracts/search?q=Herve%20Aubert"> Herve Aubert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microwave interrogation in the range 10-100 GHz is identified as an advanced technique to investigate simultaneously shock and particle velocity measurements. However, it requires the understanding of electromagnetic wave propagation in a multi-layered moving media. The existing models limit their approach to wave guides or evaluate the velocities with a fitting method, restricting therefore the domain of validity and the precision of the results. Moreover, few data of permittivity on high explosives at these frequencies under dynamic compression have been reported. In this paper, shock and particle velocities are computed concurrently for steady and unsteady shocks for various inert and reactive materials, via a propagation model based on Doppler shifts and signal amplitude. Refractive index of the material under compression is also calculated. From experimental data processing, it is demonstrated that Hugoniot curve can be evaluated. The comparison with published results proves the accuracy of the proposed method. This microwave interrogation technique seems promising for shock and detonation waves studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20propagation" title="electromagnetic propagation">electromagnetic propagation</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20setup" title=" experimental setup"> experimental setup</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugoniot%20measurement" title=" Hugoniot measurement"> Hugoniot measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=shock%20propagation" title=" shock propagation"> shock propagation</a> </p> <a href="https://publications.waset.org/abstracts/72540/shock-and-particle-velocity-determination-from-microwave-interrogation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72540.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">213</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">75</span> Efficiency of Modified Granular Activated Carbon Coupled with Membrane Bioreactor for Trace Organic Contaminants Removal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mousaab%20Alrhmoun">Mousaab Alrhmoun</a>, <a href="https://publications.waset.org/abstracts/search?q=Magali%20Casellas"> Magali Casellas</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Baudu"> Michel Baudu</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Dagot"> Christophe Dagot </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the study is to improve removal of trace organic contaminants dissolved in activated sludge by the process of filtration with membrane bioreactor combined with modified activated carbon, for a maximum removal of organic compounds characterized by low molecular weight.

This awareness has prompted the development of new products more environmentally friendly. Among these products are biocomposite materials reinforced with natural fibers. The main challenge in developing the use of biocomposites in exterior applications is the lack of knowledge about their durability and the evolution of their mechanical and physico-chemical properties in the long term. Few studies have been carried out on the photooxidation of unidirectional (UD) composites based on recycled matrix, which is the aim of this work. For this purpose, UD flax fiber composites based on recycled polypropylene were prepared by thermocompression. An accelerated aging test was carried out using a xenon arc WeatherOmeter. The consequences of UV exposure on the chemical composition and morphology of the surface of composites as well as on their tensile mechanical properties have been reported. The results showed that accelerated aging had a significant effect on the surface of these composites while it had little impact on their mechanical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flax%20fiber" title="flax fiber">flax fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=photooxidation" title=" photooxidation"> photooxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=physico-chemical%20properties" title=" physico-chemical properties"> physico-chemical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20polypropylene" title=" recycled polypropylene"> recycled polypropylene</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20properties" title=" tensile properties"> tensile properties</a> </p> <a href="https://publications.waset.org/abstracts/141984/accelerated-ageing-of-unidirectional-flax-fibers-reinforced-recycled-polypropylene-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141984.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">199</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">72</span> Sea-Spray Calculations Using the MESO-NH Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alix%20Limoges">Alix Limoges</a>, <a href="https://publications.waset.org/abstracts/search?q=William%20Bruch"> William Bruch</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Yohia"> Christophe Yohia</a>, <a href="https://publications.waset.org/abstracts/search?q=Jacques%20Piazzola"> Jacques Piazzola</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A number of questions arise concerning the long-term impact of the contribution of marine aerosol fluxes generated at the air-sea interface on the occurrence of intense events (storms, floods, etc.) in the coastal environment. To this end, knowledge is needed on sea-spray emission rates and the atmospheric dynamics of the corresponding particles. Our aim is to implement the mesoscale model MESO-NH on the study area using an accurate sea-spray source function to estimate heat fluxes and impact on the precipitations. Based on an original and complete sea-spray source function, which covers a large size spectrum since taking into consideration the sea-spray produced by both bubble bursting and surface tearing process, we propose a comparison between model simulations and experimental data obtained during an oceanic scientific cruise on board the navy ship Atalante. The results show the relevance of the sea-spray flux calculations as well as their impact on the heat fluxes and AOD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20models" title="atmospheric models">atmospheric models</a>, <a href="https://publications.waset.org/abstracts/search?q=sea-spray%20source" title=" sea-spray source"> sea-spray source</a>, <a href="https://publications.waset.org/abstracts/search?q=sea-spray%20dynamics" title=" sea-spray dynamics"> sea-spray dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=aerosols" title=" aerosols"> aerosols</a> </p> <a href="https://publications.waset.org/abstracts/148639/sea-spray-calculations-using-the-meso-nh-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148639.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">149</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">71</span> Visual and Chemical Servoing of a Hexapod Robot in a Confined Environment Using Jacobian Estimator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guillaume%20Morin-Duponchelle">Guillaume Morin-Duponchelle</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Nait%20Chabane"> Ahmed Nait Chabane</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Zerr"> Benoit Zerr</a>, <a href="https://publications.waset.org/abstracts/search?q=Pierre%20Schoesetters"> Pierre Schoesetters</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Industrial inspection can be achieved through robotic systems, allowing visual and chemical servoing. A popular scheme for visual servo-controlled robotic is the image-based servoing sys-tems. In this paper, an approach of visual and chemical servoing of a hexapod robot using a visual and chemical Jacobian matrix are proposed. The basic idea behind the visual Jacobian matrix is modeling the differential relationship between the camera system and the robotic control system to detect and track accurately points of interest in confined environments. This approach allows the robot to easily detect and navigates to the QR code or seeks a gas source localization using surge cast algorithm. To track the QR code target, a visual servoing based on Jacobian matrix is used. For chemical servoing, three gas sensors are embedded on the hexapod. A Jacobian matrix applied to the gas concentration measurements allows estimating the direction of the main gas source. The effectiveness of the proposed scheme is first demonstrated on simulation. Finally, a hexapod prototype is designed and built and the experimental validation of the approach is presented and discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20servoing" title="chemical servoing">chemical servoing</a>, <a href="https://publications.waset.org/abstracts/search?q=hexapod%20robot" title=" hexapod robot"> hexapod robot</a>, <a href="https://publications.waset.org/abstracts/search?q=Jacobian%20matrix" title=" Jacobian matrix"> Jacobian matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20servoing" title=" visual servoing"> visual servoing</a>, <a href="https://publications.waset.org/abstracts/search?q=navigation" title=" navigation"> navigation</a> </p> <a href="https://publications.waset.org/abstracts/128919/visual-and-chemical-servoing-of-a-hexapod-robot-in-a-confined-environment-using-jacobian-estimator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128919.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">125</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">70</span> Evolution under Length Constraints for Convolutional Neural Networks Architecture Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ousmane%20Youme">Ousmane Youme</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean%20Marie%20Dembele"> Jean Marie Dembele</a>, <a href="https://publications.waset.org/abstracts/search?q=Eugene%20Ezin"> Eugene Ezin</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Cambier"> Christophe Cambier</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, the convolutional neural networks (CNN) architectures designed by evolution algorithms have proven to be competitive with handcrafted architectures designed by experts. However, these algorithms need a lot of computational power, which is beyond the capabilities of most researchers and engineers. To overcome this problem, we propose an evolution architecture under length constraints. It consists of two algorithms: a search length strategy to find an optimal space and a search architecture strategy based on a genetic algorithm to find the best individual in the optimal space. Our algorithms drastically reduce resource costs and also keep good performance. On the Cifar-10 dataset, our framework presents outstanding performance with an error rate of 5.12% and only 4.6 GPU a day to converge to the optimal individual -22 GPU a day less than the lowest cost automatic evolutionary algorithm in the peer competition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CNN%20architecture" title="CNN architecture">CNN architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=evolution%20algorithm" title=" evolution algorithm"> evolution algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=length%20constraints" title=" length constraints"> length constraints</a> </p> <a href="https://publications.waset.org/abstracts/154373/evolution-under-length-constraints-for-convolutional-neural-networks-architecture-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154373.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">128</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">69</span> Evaluation of Carbon Dioxide Pressure through Radial Velocity Difference in Arterial Blood Modeled by Drift Flux Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aicha%20Rima%20Cheniti">Aicha Rima Cheniti</a>, <a href="https://publications.waset.org/abstracts/search?q=Hatem%20Besbes"> Hatem Besbes</a>, <a href="https://publications.waset.org/abstracts/search?q=Joseph%20Haggege"> Joseph Haggege</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Sintes"> Christophe Sintes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we are interested to determine the carbon dioxide pressure in the arterial blood through radial velocity difference.

Thus, it is critical to study the channel propagation characteristics in Low Power Wide Area Network (LPWAN), especially Long Range Wide Area Network (LoRaWAN). In this paper, an in-depth investigation of the reciprocity between the uplink and downlink Channel State Information (CSI) is done by performing an outdoor measurement campaign in the area of Campus Beaulieu in Rennes. At each different location, the CSI reciprocity is quantified using the Pearson Correlation Coefficient (PCC) which shows a very high linear correlation between the uplink and downlink CSI. This reciprocity feature could be utilized for the physical layer security between the node and the gateway. On the other hand, most of the CSI shapes from different locations are highly uncorrelated from each other. Hence, it can be anticipated that this could achieve significant localization gain by utilizing the frequency hopping in the LoRa systems by getting access to a wider band. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IoT" title="IoT">IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=LPWAN" title=" LPWAN"> LPWAN</a>, <a href="https://publications.waset.org/abstracts/search?q=LoRa" title=" LoRa"> LoRa</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20signal%20power" title=" effective signal power"> effective signal power</a>, <a href="https://publications.waset.org/abstracts/search?q=onsite%20measurement" title=" onsite measurement"> onsite measurement</a> </p> <a href="https://publications.waset.org/abstracts/137827/spatial-correlation-of-channel-state-information-in-real-long-range-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137827.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">162</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">67</span> Molecular Survey and Genetic Diversity of Bartonella henselae Strains Infecting Stray Cats from Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naouelle%20Azzag">Naouelle Azzag</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Haddad"> Nadia Haddad</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Durand"> Benoit Durand</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Petit"> Elisabeth Petit</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ammouche"> Ali Ammouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Chomel"> Bruno Chomel</a>, <a href="https://publications.waset.org/abstracts/search?q=Henri%20J.%20Boulouis"> Henri J.

In this research, we report the results of a cross sectional study of Bartonella henselae bacteremia in stray cats from Algiers. Whole blood of 227 stray cats from Algiers was tested for the presence of Bartonella species by culture and for the evaluation of the genetic diversity of B. henselae strains by multi-locus variable number of tandem repeats assay (MLVA). Bacteremia prevalence was 17% and only B. henselae was identified. Type I was the predominant type (64%). MLVA typing of 259 strains from 30 bacteremic cats revealed 52 different profiles. 51 of these profiles were specific to Algerian cats/identified for the first time. 20/30 cats (67%) harbored 2 to 7 MLVA profiles simultaneously. The similarity of MLVA profiles obtained from the same cat, neighbor-joining clustering and structure-neighbor clustering showed that such a diversity likely results from two different mechanisms occurring either independently or simultaneously independent infections and genetic drift from a primary strain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bartonella" title="Bartonella">Bartonella</a>, <a href="https://publications.waset.org/abstracts/search?q=cat" title=" cat"> cat</a>, <a href="https://publications.waset.org/abstracts/search?q=MLVA" title=" MLVA"> MLVA</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic" title=" genetic"> genetic</a> </p> <a href="https://publications.waset.org/abstracts/108213/molecular-survey-and-genetic-diversity-of-bartonella-henselae-strains-infecting-stray-cats-from-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108213.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">149</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">66</span> Application of the Quantile Regression Approach to the Heterogeneity of the Fine Wine Prices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Charles-Olivier%20Am%C3%A9d%C3%A9e-Manesme">Charles-Olivier Amédée-Manesme</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Faye"> Benoit Faye</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20Le%20Fur"> Eric Le Fur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the heterogeneity of the Bordeaux Legends 50 wine market price segment is addressed. For this purpose, quantile regression is applied – with market segmentation based on wine bottle price quantile – and the hedonic price of wine attributes is computed for various price segments of the market. The approach is applied to a major privately held data set which consists of approximately 30,000 transactions over the 2003–2014 period. The findings suggest that the relative hedonic prices of several wine attributes differ significantly among deciles. In particular, the elasticity coefficient of the expert ratings shows strong variation among prices. If - as suggested in the literature - expert ratings have a positive influence on wine price on average, they have a clearly decreasing impact over the quantiles. Finally, the lower the wine price, the higher the potential for price appreciation over time. Other variables such as chateaux or vintage are also shown to vary across the distribution of wine prices. While enhancing our understanding of the complex market dynamics that underlie Bordeaux wines’ price, this research provides empirical evidence that the QR approach adequately captures heterogeneity among wine price ranges, which simultaneously applies to wine stock, vintage and auctions’ house. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hedonics" title="hedonics">hedonics</a>, <a href="https://publications.waset.org/abstracts/search?q=market%20segmentation" title=" market segmentation"> market segmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=quantile%20regression" title=" quantile regression"> quantile regression</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneity" title=" heterogeneity"> heterogeneity</a>, <a href="https://publications.waset.org/abstracts/search?q=wine%20economics" title=" wine economics"> wine economics</a> </p> <a href="https://publications.waset.org/abstracts/70068/application-of-the-quantile-regression-approach-to-the-heterogeneity-of-the-fine-wine-prices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70068.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">340</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">65</span> Evaluation of Bioactive Phenols in Blueberries from Different Cultivars</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Gon%C3%A7alves">Christophe Gonçalves</a>, <a href="https://publications.waset.org/abstracts/search?q=Raquel%20P.%20F.%20Guin%C3%A9"> Raquel P.

In this way, a study was done to determine the phenolic composition (total phenols, anthocyanins and tannins) and antioxidant activity of blueberries from three cultivars (Duke, Bluecrop, and Ozarblue) grown in two different Portuguese farms. Initially two successive extractions were done with methanol followed by two extractions with aqueous acetone solutions. These extracts obtained were then used to evaluate the amount of phenolic compounds and the antioxidant activity. The total phenols were observed to vary from 4.9 to 8.2 mg GAE/g fresh weight, with anthocyanin’s contents in the range 1.5-2.8 mg EMv3G/g and tannins contents in the range 1.5- 3.8 mg/g. The results for antioxidant activity ranged from 9.3 to 23.2 mol TE/g, and from 24.7 to 53.4 mol TE/g, when measured, respectively, by DPPH and ABTS methods. In conclusion it was observed that, in general, the cultivar had a visible effect on the phenols present, and furthermore, the geographical origin showed relevance either in the phenols contents or the antioxidant activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthocyanins" title="anthocyanins">anthocyanins</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=blueberry%20cultivar" title=" blueberry cultivar"> blueberry cultivar</a>, <a href="https://publications.waset.org/abstracts/search?q=geographical%20origin" title=" geographical origin"> geographical origin</a>, <a href="https://publications.waset.org/abstracts/search?q=phenolic%20compounds" title=" phenolic compounds"> phenolic compounds</a> </p> <a href="https://publications.waset.org/abstracts/22045/evaluation-of-bioactive-phenols-in-blueberries-from-different-cultivars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22045.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">474</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">64</span> Characterization of Shrinkage-Induced Cracking of Clay Soils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20El%20Hajjar">Ahmad El Hajjar</a>, <a href="https://publications.waset.org/abstracts/search?q=Joanna%20Eid"> Joanna Eid</a>, <a href="https://publications.waset.org/abstracts/search?q=Salima%20Bouchemella"> Salima Bouchemella</a>, <a href="https://publications.waset.org/abstracts/search?q=Tariq%20Ouahbi"> Tariq Ouahbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Duchemin"> Benoit Duchemin</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Taibi"> Said Taibi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In our present society, raw earth presents an alternative as an energy-saving building material for dealing with climate and environmental issues. Nevertheless, it has a sensitivity to water, due to the presence of fines, which has a direct effect on its consistency. This can be expressed during desiccation, by shrinkage deformations resulting in cracking that begins once the internal tensile stresses developed, due to suction, exceed the tensile strength of the material. This work deals with the evolution of the strain of clay samples, from the beginning of shrinkage until the initiation of crack, using the DIC (Digital Image Correlation) technique. In order to understand the origin of cracking, desiccation is studied for different boundary conditions and depending on the intrinsic characteristics of the material. On the other hand, a study of restrained shrinkage is carried out on the ring test to investigate the ultimate tensile strength from which the crack begins in the dough of clay. The purpose of this test is to find the type of reinforcement adapted to thwart in the cracking of the material. A microscopic analysis of the damaged area is necessary to link the macroscopic mechanisms of cracking to the various physicochemical phenomena at the microscopic scale in order to understand the different microstructural mechanisms and their impact on the macroscopic shrinkage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clayey%20soil" title="clayey soil">clayey soil</a>, <a href="https://publications.waset.org/abstracts/search?q=shrinkage" title=" shrinkage"> shrinkage</a>, <a href="https://publications.waset.org/abstracts/search?q=strain" title=" strain"> strain</a>, <a href="https://publications.waset.org/abstracts/search?q=cracking" title=" cracking"> cracking</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20image%20correlation" title=" digital image correlation"> digital image correlation</a> </p> <a href="https://publications.waset.org/abstracts/98463/characterization-of-shrinkage-induced-cracking-of-clay-soils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98463.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">161</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">63</span> Estimation of Fouling in a Cross-Flow Heat Exchanger Using Artificial Neural Network Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rania%20Jradi">Rania Jradi</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Marvillet"> Christophe Marvillet</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Razak%20Jeday"> Mohamed Razak Jeday</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the most frequently encountered problems in industrial heat exchangers is fouling, which degrades the thermal and hydraulic performances of these types of equipment, leading thus to failure if undetected. And it occurs due to the accumulation of undesired material on the heat transfer surface. So, it is necessary to know about the heat exchanger fouling dynamics to plan mitigation strategies, ensuring a sustainable and safe operation. This paper proposes an Artificial Neural Network (ANN) approach to estimate the fouling resistance in a cross-flow heat exchanger by the collection of the operating data of the phosphoric acid concentration loop. The operating data of 361 was used to validate the proposed model. The ANN attains AARD= 0.048%, MSE= 1.811x10⁻¹¹, RMSE= 4.256x 10⁻⁶ and r²=99.5 % of accuracy which confirms that it is a credible and valuable approach for industrialists and technologists who are faced with the drawbacks of fouling in heat exchangers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross-flow%20heat%20exchanger" title="cross-flow heat exchanger">cross-flow heat exchanger</a>, <a href="https://publications.waset.org/abstracts/search?q=fouling" title=" fouling"> fouling</a>, <a href="https://publications.waset.org/abstracts/search?q=estimation" title=" estimation"> estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphoric%20acid%20concentration%20loop" title=" phosphoric acid concentration loop"> phosphoric acid concentration loop</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network%20approach" title=" artificial neural network approach"> artificial neural network approach</a> </p> <a href="https://publications.waset.org/abstracts/140600/estimation-of-fouling-in-a-cross-flow-heat-exchanger-using-artificial-neural-network-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140600.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">197</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">62</span> Physics of Decision for Polling Place Management: A Case Study from the 2020 USA Presidential Election</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nafe%20Moradkhani">Nafe Moradkhani</a>, <a href="https://publications.waset.org/abstracts/search?q=Frederick%20Benaben"> Frederick Benaben</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Montreuil"> Benoit Montreuil</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Vatankhah%20Barenji"> Ali Vatankhah Barenji</a>, <a href="https://publications.waset.org/abstracts/search?q=Dima%20Nazzal"> Dima Nazzal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the context of the global pandemic, the practical management of the 2020 presidential election in the USA was a strong concern. To anticipate and prepare for this election accurately, one of the main challenges was to confront (i) forecasts of voter turnout, (ii) capacities of the facilities and, (iii) potential configuration options of resources. The approach chosen to conduct this anticipative study consists of collecting data about forecasts and using simulation models to work simultaneously on resource allocation and facility configuration of polling places in Fulton County, Georgia’s largest county. A polling place is a dedicated facility where voters cast their ballots in elections using different devices. This article presents the results of the simulations of such places facing pre-identified potential risks. These results are oriented towards the efficiency of these places according to different criteria (health, trust, comfort). Then a dynamic framework is introduced to describe risks as physical forces perturbing the efficiency of the observed system. Finally, the main benefits and contributions resulting from this simulation campaign are presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=performance" title="performance">performance</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20support" title=" decision support"> decision support</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=election" title=" election"> election</a>, <a href="https://publications.waset.org/abstracts/search?q=pandemics" title=" pandemics"> pandemics</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20system" title=" information system"> information system</a> </p> <a href="https://publications.waset.org/abstracts/136683/physics-of-decision-for-polling-place-management-a-case-study-from-the-2020-usa-presidential-election" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136683.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">151</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">61</span> Capuchin Monkeys Sharing Their Food at a Cost of Themselves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beno%C3%AEt%20Bucher">Benoît Bucher</a>, <a href="https://publications.waset.org/abstracts/search?q=Hika%20Kuroshima"> Hika Kuroshima</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazuo%20Fujita"> Kazuo Fujita</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although altruism is commonly observed in humans and is considered one of the most important factors in the survival of our species, its cognitive mechanisms and evolutionary roots are yet to be explained. This study is based on the previous findings that bonobos (Pan Paniscus) preferred to share a limited amount of food with others regardless of their relationships with the others. Findings such as this suggest that humans’ propensity for altruistic food-sharing may be shared among apes and may have evolved much longer ago than previously considered. We thus adapted the previous experimental design using tufted capuchins (Cebus apella), New World monkeys separating from humans about 40 million years ago. In order to achieve this, 12 pairs of capuchins (consisting of a benefactors and a partner) were tested in a row of two adjacent cages separated by a swinging door locked by a key (Fig.1). We observed whether the monkeys in possession of food (the benefactors) would allow their partner to enter their cage by unlocking the door between them. Results showed that the monkeys clearly preferred to monopolize the food for themselves, even though they in a few cases unlocked the door after eating the preferred food. This suggests that this species, which has been shown to be sensitive to the others’ welfare, would not actively share food at a cost of their own. Although further studies are needed, our results suggest the existence of significant differences in the evolutionary development of the pro social tendencies between bonobos and capuchin monkeys. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=altruism" title="altruism">altruism</a>, <a href="https://publications.waset.org/abstracts/search?q=capuchin%20monkeys" title=" capuchin monkeys"> capuchin monkeys</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20sharing" title=" food sharing"> food sharing</a>, <a href="https://publications.waset.org/abstracts/search?q=pro%20social%20behaviors" title=" pro social behaviors"> pro social behaviors</a> </p> <a href="https://publications.waset.org/abstracts/10569/capuchin-monkeys-sharing-their-food-at-a-cost-of-themselves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10569.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">453</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">60</span> Finite Element Modeling of the Mechanical Behavior of Municipal Solid Waste Incineration Bottom Ash with the Mohr-Coulomb Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Le%20Ngoc%20Hung">Le Ngoc Hung</a>, <a href="https://publications.waset.org/abstracts/search?q=Abriak%20Nor%20Edine"> Abriak Nor Edine</a>, <a href="https://publications.waset.org/abstracts/search?q=Binetruy%20Christophe"> Binetruy Christophe</a>, <a href="https://publications.waset.org/abstracts/search?q=Benzerzour%20Mahfoud"> Benzerzour Mahfoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahrour%20Isam"> Shahrour Isam</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrice%20Rivard"> Patrice Rivard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bottom ash from Municipal Solid Waste Incineration (MSWI) can be viewed as a typical granular material because these industrial by-products result from the incineration of various domestic wastes. MSWI bottom ashes are mainly used in road engineering in substitution of the traditional natural aggregates. As the characterization of their mechanical behavior is essential in order to use them, specific studies have been led over the past few years. In the first part of this paper, the mechanical behavior of MSWI bottom ash is studied with triaxial tests. After analysis of the experiment results, the simulation of triaxial tests is carried out by using the software package CESAR-LCPC. As the first approach in modeling of this new class material, the Mohr-Coulomb model was chosen to describe the evolution of material under the influence of external mechanical actions. <p
