innovative way of determining the driving context for a driving assistance system. We invoke the fusion of all parameters that describe the context of the environment, the vehicle and the driver to obtain the driving context. We created a training set that stores driving situation patterns and from which the system consults to determine the driving situation. A machine-learning algorithm predicts the driving situation. The driving situation is an input to the fission process that yields the action that must be implemented when the driver needs to be informed or assisted from the given the driving situation. The action may be directed towards the driver, the vehicle or both. This is an ongoing work whose goal is to offer an alternative driving assistance system for safe driving, green driving and comfortable driving. Here, ontologies are used for knowledge representation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive%20driving" title="cognitive driving">cognitive driving</a>, <a href="https://publications.waset.org/abstracts/search?q=intelligent%20transportation%20system" title=" intelligent transportation system"> intelligent transportation system</a>, <a href="https://publications.waset.org/abstracts/search?q=multimodal%20system" title=" multimodal system"> multimodal system</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology" title=" ontology"> ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a> </p> <a href="https://publications.waset.org/abstracts/79015/cognition-of-driving-context-for-driving-assistance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79015.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">368</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> Introducing the Digital Backpack: Looking at Ivory Coast </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eunice%20H.%20Li">Eunice H. Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This e-Poster presents how the ‘digital backpack’ was introduced to primary school children in Ivory Coast. The idea of a ‘digital backpack’ was initiated by Mr. Thierry N’Doufou in 2012, who later designed and presented to the rest of the world in September 2014. The motivation behind the backpack was to relieve children of the heavy-weight they carry in their school backpacks. Another motivation was to promote Ivory Coast as a country where all children are brought into the digital era. Thierry N’Doufou regards education as the means by which his nation and the entire African Continent can be developed as a prosperous territory. The ‘digital backpack’ contains the entire curriculum for each class and favours a constructivist approach to learning. The children’s notes and exercises are also included in the pack. Additionally, teachers and parents are able to monitor remotely children’s activities while they are working with the ‘backpack’. Teachers are also able to issue homework, assess student’s progress and manage the student’s coursework. This means that teachers should always think the most appropriate pedagogies that can be used to help children to learn. Furthermore, teachers, parents and fellow students are able to have conversations and discussions by using web portals. It is also possible to access more apps if children would like to have additional learning activities. From the presentation in the e-Poster, it seems reasonable to conclude that the ‘digital backpack’ has potential to reach other-level of education. In this way, all will be able to benefit from this new invention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pedagogy" title="pedagogy">pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=curriculum" title=" curriculum"> curriculum</a>, <a href="https://publications.waset.org/abstracts/search?q=constructivism" title=" constructivism"> constructivism</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20constructivism" title=" social constructivism"> social constructivism</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20learning%20environment" title=" distance learning environment"> distance learning environment</a>, <a href="https://publications.waset.org/abstracts/search?q=ubiquitous%20learning%20environment" title=" ubiquitous learning environment"> ubiquitous learning environment</a> </p> <a href="https://publications.waset.org/abstracts/20906/introducing-the-digital-backpack-looking-at-ivory-coast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20906.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">659</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> Cash Flow Optimization on Synthetic CDOs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timoth%C3%A9e%20Bligny">Timothée Bligny</a>, <a href="https://publications.waset.org/abstracts/search?q=Cl%C3%A9ment%20Codron"> Clément Codron</a>, <a href="https://publications.waset.org/abstracts/search?q=Antoine%20Estruch"> Antoine Estruch</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Girodet"> Nicolas Girodet</a>, <a href="https://publications.waset.org/abstracts/search?q=Cl%C3%A9ment%20Ginet"> Clément Ginet</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Collateralized Debt Obligations are not as widely used nowadays as they were before 2007 Subprime crisis. Nonetheless there remains an enthralling challenge to optimize cash flows associated with synthetic CDOs. A Gaussian-based model is used here in which default correlation and unconditional probabilities of default are highlighted. Then numerous simulations are performed based on this model for different scenarios in order to evaluate the associated cash flows given a specific number of defaults at different periods of time. Cash flows are not solely calculated on a single bought or sold tranche but rather on a combination of bought and sold tranches. With some assumptions, the simplex algorithm gives a way to find the maximum cash flow according to correlation of defaults and maturities. The used Gaussian model is not realistic in crisis situations. Besides present system does not handle buying or selling a portion of a tranche but only the whole tranche. However the work provides the investor with relevant elements on how to know what and when to buy and sell. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=synthetic%20collateralized%20debt%20obligation%20%28CDO%29" title="synthetic collateralized debt obligation (CDO)">synthetic collateralized debt obligation (CDO)</a>, <a href="https://publications.waset.org/abstracts/search?q=credit%20default%20swap%20%28CDS%29" title=" credit default swap (CDS)"> credit default swap (CDS)</a>, <a href="https://publications.waset.org/abstracts/search?q=cash%20flow%20optimization" title=" cash flow optimization"> cash flow optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=probability%20of%20default" title=" probability of default"> probability of default</a>, <a href="https://publications.waset.org/abstracts/search?q=default%20correlation" title=" default correlation"> default correlation</a>, <a href="https://publications.waset.org/abstracts/search?q=strategies" title=" strategies"> strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=simplex" title=" simplex "> simplex </a> </p> <a href="https://publications.waset.org/abstracts/10900/cash-flow-optimization-on-synthetic-cdos" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10900.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">274</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> Coupling of Reticular and Fuzzy Set Modelling in the Analysis of the Action Chains from Socio-Ecosystem, Case of the Renewable Natural Resources Management in Madagascar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Ganomanana">Thierry Ganomanana</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominique%20Herv%C3%A9"> Dominique Hervé</a>, <a href="https://publications.waset.org/abstracts/search?q=Solo%20Randriamahaleo"> Solo Randriamahaleo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Management of Malagasy renewable natural re-sources allows, in the case of forest, the mobilization of several actors with norms and/or territory.

They act as electron transport layers, and they permit the charge separation. They are also the substrate for the preparation of perovskite in the direct architecture. Therefore, they have a strong influence on the perovskite loading, its crystallinity and they can induce a degradation phenomenon upon annealing. The interface between the oxide and the perovskite is important, and the quality of this heterointerface must be optimized to limit the recombination of charges phenomena and performance losses. One can also play on the oxide and use two oxide contact layers for improving the device stability and durability. These aspects will be developed and illustrated on the basis of recent results obtained at Chimie-ParisTech. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oxide" title="oxide">oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20perovskite" title=" hybrid perovskite"> hybrid perovskite</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cells" title=" solar cells"> solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=impedance" title=" impedance"> impedance</a> </p> <a href="https://publications.waset.org/abstracts/65396/key-roles-of-the-n-type-oxide-layer-in-hybrid-perovskite-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65396.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">315</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> Experimental Investigation and Numerical Simulations of the Cylindrical Machining of a Ti-6Al-4V Tree</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Sahli">Mohamed Sahli</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Bassir"> David Bassir</a>, <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Barriere"> Thierry Barriere</a>, <a href="https://publications.waset.org/abstracts/search?q=Xavier%20Roizard"> Xavier Roizard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Predicting the behaviour of the Ti-6Al-4V alloy during the turning operation was very important in the choice of suitable cutting tools and also in the machining strategies.

However, affordances are key to engaging students and enabling teachers to actualize learning goals. E-learning systems (software and artifacts) need to be designed in such a way that the features facilitate perceptions of the affordances with minimal cognition. This study aimed to fill this gap in the literature and encourage further research in this area. It provides guidelines for facilitating the perception of affordances in e-learning design and advances Technology Affordance and Constraints Theory by incorporating the affordance-based design process, the principles of multimedia learning, e-learning design philosophy, and emotional and cognitive affordances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-learning" title="e-learning">e-learning</a>, <a href="https://publications.waset.org/abstracts/search?q=technology%20affrodances" title=" technology affrodances"> technology affrodances</a>, <a href="https://publications.waset.org/abstracts/search?q=affordance%20based%20design" title=" affordance based design"> affordance based design</a>, <a href="https://publications.waset.org/abstracts/search?q=e-learning%20design" title=" e-learning design"> e-learning design</a> </p> <a href="https://publications.waset.org/abstracts/176036/technological-affordances-guidelines-for-e-learning-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176036.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">62</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">59</span> Design Parameters Optimization of a Gas Turbine with Exhaust Gas Recirculation: An Energy and Exergy Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joe%20Hachem">Joe Hachem</a>, <a href="https://publications.waset.org/abstracts/search?q=Marianne%20Cuif-Sjostrand"> Marianne Cuif-Sjostrand</a>, <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Schuhler"> Thierry Schuhler</a>, <a href="https://publications.waset.org/abstracts/search?q=Dominique%20Orhon"> Dominique Orhon</a>, <a href="https://publications.waset.org/abstracts/search?q=Assaad%20Zoughaib"> Assaad Zoughaib</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The exhaust gas recirculation, EGR, implementation on gas turbines is increasingly gaining the attention of many researchers. This emerging technology presents many advantages, such as lowering the NOx emissions and facilitating post-combustion carbon capture as the carbon dioxide concentration in the cycle increases. As interesting as this technology may seem, the gas turbine, or its thermodynamic equivalent, the Brayton cycle, shows an intrinsic efficiency decrease with increasing EGR rate. In this paper, a thermodynamic model is presented to show the cycle efficiency decrease with EGR, alternative values of design parameters of both the pressure ratio (PR) and the turbine inlet temperature (TIT) are then proposed to optimize the cycle efficiency with different EGR rates. Results show that depending on the given EGR rate, both the design PR & TIT should be increased to compensate for the deficit in efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas%20turbines" title="gas turbines">gas turbines</a>, <a href="https://publications.waset.org/abstracts/search?q=exhaust%20gas%20recirculation" title=" exhaust gas recirculation"> exhaust gas recirculation</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20parameters%20optimization" title=" design parameters optimization"> design parameters optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=thermodynamic%20approach" title=" thermodynamic approach"> thermodynamic approach</a> </p> <a href="https://publications.waset.org/abstracts/135673/design-parameters-optimization-of-a-gas-turbine-with-exhaust-gas-recirculation-an-energy-and-exergy-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135673.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">145</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">58</span> Investigating the Demand of Short-Shelf Life Food Products for SME Wholesalers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yamini%20Raju">Yamini Raju</a>, <a href="https://publications.waset.org/abstracts/search?q=Parminder%20S.%20Kang"> Parminder S.

One to twenty mol% of YO3/2 were either added into the glass matrix or substituted for gallium oxide. The glass structure was studied by Raman spectroscopy, and the thermal, optical, thermo-mechanical and physical properties are examined. The introduction of yttrium ions in both glass series increases the glass transition temperature, crystallization temperature, softening temperature, coefficient of linear thermal expansion and density. Through differential scanning calorimetry and X-ray diffraction analyses, it was found that competition occurs between the gallo-germanate zeolite-type phase and the yttrium-containing phase. From 13 mol% of YO3/2, the yttrium introduction impedes the formation of surface crystallization in these glasses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photonic" title="photonic">photonic</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy-metal%20oxide" title=" heavy-metal oxide"> heavy-metal oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=glass" title=" glass"> glass</a>, <a href="https://publications.waset.org/abstracts/search?q=crystallization" title=" crystallization"> crystallization</a> </p> <a href="https://publications.waset.org/abstracts/167712/the-key-role-of-yttrium-oxide-on-devitrification-resilience-of-barium-gallo-germanate-glasses-physicochemical-properties-and-crystallization-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167712.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">145</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">56</span> Wave Interaction with Defects in Pressurized Composite Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20K.%20Apalowo">R.

The object of study is photography regarding as a kind of art which demands specific system of quality marking. Objective: To define aesthetic criteria in photography art. For current searching different kind of texts by such powerful authors like Clement Greenberg and Rosalind Krauss, Theodor Adorno and Herbert Marcuse, Charlott Cotton and Boris Groys, Viktor Miziano and Ekaterina Degot' were analyzed. Before all, there are two different kinds of photography: the classic art photography (by Ansel Adams) and the photography as kind of art (by Andreas Gursky). In this text we are talking about the photography as kind of art. The main principle of current searching is synthesis of two different approaches: modernism and postmodernism. This method helps us to define uniform criteria of aesthetic quality in photography as kind of art. The criteria mentioned in conclusion paragraph are: aesthetic rationality, aesthetic economy, awareness (using photographic technics or references), and intention to go beyond form, practice and method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aesthetic" title="aesthetic">aesthetic</a>, <a href="https://publications.waset.org/abstracts/search?q=art" title=" art"> art</a>, <a href="https://publications.waset.org/abstracts/search?q=criteria%20of%20quality" title=" criteria of quality"> criteria of quality</a>, <a href="https://publications.waset.org/abstracts/search?q=photography" title=" photography"> photography</a>, <a href="https://publications.waset.org/abstracts/search?q=visually" title=" visually"> visually</a> </p> <a href="https://publications.waset.org/abstracts/40285/the-criteria-of-the-aesthetic-quality-of-art-contemporary-photography" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40285.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">418</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">53</span> Characterization of Complex Electromagnetic Environment Created by Multiple Sources of Electromagnetic Radiation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Clement%20Temaneh-Nyah">Clement Temaneh-Nyah</a>, <a href="https://publications.waset.org/abstracts/search?q=Josiah%20Makiche"> Josiah Makiche</a>, <a href="https://publications.waset.org/abstracts/search?q=Josephine%20Nujoma"> Josephine Nujoma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper considers the characterisation of a complex electromagnetic environment due to multiple sources of electromagnetic radiation as a five-dimensional surface which can be described by a set of several surface sections including: instant EM field intensity distribution maps at a given frequency and altitude, instantaneous spectrum at a given location in space and the time evolution of the electromagnetic field spectrum at a given point in space.

The usage of the poling for second optical harmonic generation, fabrication of optical waveguides and electrooptic modulators was also reported. Nevertheless, the detailed description of the poling of glasses, containing multiple charge carriers is still under discussion. In particular, the role of possible migration of electrons in the space charge formation usually remains out of the question. In this work, we performed the numerical simulation of thermal poling of a silicate glass, containing Na, K, Mg, and Ca. We took into consideration the contribution of electrons in the polarization process. The possible explanation of migration of electrons can be the break of non-bridging oxygen bonds. It was found, that the modeled depth of the space charge region is about 10 times higher if the migration of the negative charges is taken under consideration. The simulated profiles of cations, participating in the polarization process, are in a good agreement with the experimental data, obtained by glow discharge spectroscopy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glass%20poling" title="glass poling">glass poling</a>, <a href="https://publications.waset.org/abstracts/search?q=charge%20transport" title=" charge transport"> charge transport</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=concentration%20profiles" title=" concentration profiles"> concentration profiles</a> </p> <a href="https://publications.waset.org/abstracts/67507/polarization-of-glass-with-positive-and-negative-charge-carriers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67507.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">359</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">51</span> Calculating Collision Risk Exposures and Risk Probabilities at Container Terminals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Ali%20Hasanzadeh">Mohammad Ali Hasanzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Vanelslander"> Thierry Vanelslander</a>, <a href="https://publications.waset.org/abstracts/search?q=Eddy%20Van%20De%20Voorde"> Eddy Van De Voorde</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays maritime transport is a key element in international trade and global supply chain. Economies of scale in transporting goods are one of the most attractive elements of using ships. Without maritime transport, almost no globalization of economics can be imagined. Within maritime transport, ports are the interface between lands and see. Even though using ships help cargo owners to have a competitive margin but an accident in port during loading or unloading or even moving cargoes within the terminal can diminish such margin. Statistics shows that due to the high-speed notion of activities within ports, collision accidents are the most common type of accidents. To mitigate such accidents, the appropriate risk exposures have to be defined and calculate, later on risk probabilities can be determined for each type of accident, i.e. fatal, severe, moderate and minor ones. Having such risk probabilities help managers to define the effectiveness of each collision risk control option. This research defined travelled distance as main collision risk exposure in container terminals, taking all the related items into consideration, it was calculated for Shahid Rajae container terminals.

This wireless recording system allows us to visualize and monitor the state of the heart’s health during a surgery, even if the patient is moved from the operating theater to post anesthesia care unit. The acquired signal is transmitted via a Bluetooth unit to a PC where the data are displayed, stored and processed. To test the reliability of our system, a comparison between ECG signals processed by a conventional ECG monitoring system (Datex-Ohmeda) and by our wireless system is made. The comparison is based on the shape of the ECG signal, the duration of the QRS complex, the P and T waves, as well as the position of the ST segments with respect to the isoelectric line. The proposed system is presented and discussed. The results have confirmed that the use of Bluetooth during surgery does not affect the devices used and vice versa.

Moreover, temperature dependent wave response of composite and layered structures have been continuously studied, though still limited, in the last decade mainly due to the broad operating temperature range of aerospace structures. A wave finite element (WFE) and finite element (FE) based computational method is presented by which the temperature dependent wave dispersion characteristics and interaction phenomenon in composite structures can be predicted. Initially, the temperature dependent mechanical properties of the panel in the range of -100 ◦C to 150 ◦C are measured experimentally using the Thermal Mechanical Analysis (TMA). Temperature dependent wave dispersion characteristics of each waveguide of the structural system, which is discretized as a system of a number of waveguides coupled by a coupling element, is calculated using the WFE approach. The wave scattering properties, as a function of temperature, is determined by coupling the WFE wave characteristics models of the waveguides with the full FE modelling of the coupling element on which defect is included. Numerical case studies are exhibited for two waveguides coupled through a coupling element. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element" title="finite element">finite element</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20dependency" title=" temperature dependency"> temperature dependency</a>, <a href="https://publications.waset.org/abstracts/search?q=wave%20dispersion%20characteristics" title=" wave dispersion characteristics"> wave dispersion characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=wave%20finite%20element" title=" wave finite element"> wave finite element</a>, <a href="https://publications.waset.org/abstracts/search?q=wave%20scattering%20properties" title=" wave scattering properties"> wave scattering properties</a> </p> <a href="https://publications.waset.org/abstracts/58484/thermal-effect-on-wave-interaction-in-composite-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58484.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">309</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">48</span> Repurposing of Crystalline Solar PV For Sodium Silicate Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lawal%20Alkasim">Lawal Alkasim</a>, <a href="https://publications.waset.org/abstracts/search?q=Clement%20M.%20Gonah"> Clement M.

Silicon is the main back-bone and responsible for the thermodynamic properties of glass, ceramics and glass ceramics materials. Antireflection silicon is soluble in hot alkali. Successfully the recovered material composed of silicon and silicon nitride of the A.R, with a small amount of silver, Aluminuim, lead & copper in the sunshine of crystalline/non-crystalline silicon solar cell. Aquaregia is used to remove the silver, Aluminium, lead & copper. The recovered material treated with hot alkali highly concentrated to produce sodium silicate, which is an alkali silicate glass (water glass). This type of glass is produced through chemical process, unlike other glasses that are produced through physical process of melting and non-crystalline solidification. It has showed a property of being alkali silicate glass from its solubility in water and insoluble in alcohol. The XRF analysis shows the presence of sodium silicate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unrecyclable%20solar%20PV" title="unrecyclable solar PV">unrecyclable solar PV</a>, <a href="https://publications.waset.org/abstracts/search?q=crystalline%20silicon" title=" crystalline silicon"> crystalline silicon</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20conc.%20%20alkali" title=" hot conc. alkali"> hot conc. alkali</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20silicate" title=" sodium silicate"> sodium silicate</a> </p> <a href="https://publications.waset.org/abstracts/168585/repurposing-of-crystalline-solar-pv-for-sodium-silicate-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168585.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">100</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">47</span> Nonreciprocal Optical Effects in Plasmonic Nanoparticle Aggregates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ward%20Brullot">Ward Brullot</a>, <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Verbiest"> Thierry Verbiest</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nonreciprocal optical effects, such as Faraday rotation or magnetic circular dichroism, are very useful both for fundamental studies as for applications such as magnetic field sensors or optical isolators. In this study, we developed layer-by-layer deposited 20nm thick plasmonic nanoparticle aggregates consisting of gold, silver and magnetite nanoparticles that show broadband nonreciprocal asymmetric transmission. As such, the optical transmittance, or absorbance, depends on the direction of light propagation in the material, which means that looking from one direction or the other, more or less light passes through the sample. Theoretical analysis showed that strong electric quadrupole fields, which are electric field gradients, occur in the aggregates and that these quadrupole fields are responsible for the observed asymmetric transmission and the nonreciprocity of the effect. Apart from nonreciprocal asymmetric transmission, also other effects such as, but not limited to, optical rotation, circular dichroism or nonlinear optical responses were measured in the plasmonic nanoparticle aggregates and the influences of the intense electric quadrupole fields determined. In conclusion, the presence of strong electric quadrupole fields make the developed plasmonic nanoparticle aggregates ideal candidates for the study and application of various nonreciprocal optical effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20transmission" title="asymmetric transmission">asymmetric transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=electric%20quadrupoles" title=" electric quadrupoles"> electric quadrupoles</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticle%20aggregates" title=" nanoparticle aggregates"> nanoparticle aggregates</a>, <a href="https://publications.waset.org/abstracts/search?q=nonreciprocity" title=" nonreciprocity"> nonreciprocity</a> </p> <a href="https://publications.waset.org/abstracts/33791/nonreciprocal-optical-effects-in-plasmonic-nanoparticle-aggregates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33791.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">424</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">46</span> Synchronous Courses Attendance in Distance Higher Education: Case Study of a Computer Science Department</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Eude">Thierry Eude</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of videoconferencing platforms adapted to teaching offers students the opportunity to take distance education courses in much the same way as traditional in-class training. The sessions can be recorded and they allow students the option of following the courses synchronously or asynchronously. Three typical profiles can then be distinguished: students who choose to follow the courses synchronously, students who could attend the course in synchronous mode but choose to follow the session off-line, and students who follow the course asynchronously as they cannot attend the course when it is offered because of professional or personal constraints. Our study consists of observing attendance at all distance education courses offered in the synchronous mode by the Computer Science and Software Engineering Department at Laval University during 10 consecutive semesters. The aim is to identify factors that influence students in their choice of attending the distance courses in synchronous mode. It was found that participation tends to be relatively stable over the years for any one semester (fall, winter summer) and is similar from one course to another, although students may be increasingly familiar with the synchronous distance education courses. Average participation is around 28%. There may be deviations, but they concern only a few courses during certain semesters, suggesting that these deviations would only have occurred because of the composition of particular promotions during specific semesters. Furthermore, course schedules have a great influence on the attendance rate. The highest rates are all for courses which are scheduled outside office hours. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attendance" title="attendance">attendance</a>, <a href="https://publications.waset.org/abstracts/search?q=distance%20undergraduate%20education%20in%20computer%20science" title=" distance undergraduate education in computer science"> distance undergraduate education in computer science</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20behavior" title=" student behavior"> student behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=synchronous%20e-learning" title=" synchronous e-learning"> synchronous e-learning</a> </p> <a href="https://publications.waset.org/abstracts/57165/synchronous-courses-attendance-in-distance-higher-education-case-study-of-a-computer-science-department" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57165.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">284</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">45</span> Design of an Ensemble Learning Behavior Anomaly Detection Framework</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdoulaye%20Diop">Abdoulaye Diop</a>, <a href="https://publications.waset.org/abstracts/search?q=Nahid%20Emad"> Nahid Emad</a>, <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Winter"> Thierry Winter</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hilia"> Mohamed Hilia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Data assets protection is a crucial issue in the cybersecurity field. Companies use logical access control tools to vault their information assets and protect them against external threats, but they lack solutions to counter insider threats. Nowadays, insider threats are the most significant concern of security analysts. They are mainly individuals with legitimate access to companies information systems, which use their rights with malicious intents. In several fields, behavior anomaly detection is the method used by cyber specialists to counter the threats of user malicious activities effectively. In this paper, we present the step toward the construction of a user and entity behavior analysis framework by proposing a behavior anomaly detection model. This model combines machine learning classification techniques and graph-based methods, relying on linear algebra and parallel computing techniques. We show the utility of an ensemble learning approach in this context. We present some detection methods tests results on an representative access control dataset. The use of some explored classifiers gives results up to 99% of accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cybersecurity" title="cybersecurity">cybersecurity</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20protection" title=" data protection"> data protection</a>, <a href="https://publications.waset.org/abstracts/search?q=access%20control" title=" access control"> access control</a>, <a href="https://publications.waset.org/abstracts/search?q=insider%20threat" title=" insider threat"> insider threat</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20behavior%20analysis" title=" user behavior analysis"> user behavior analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=ensemble%20learning" title=" ensemble learning"> ensemble learning</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20performance%20computing" title=" high performance computing"> high performance computing</a> </p> <a href="https://publications.waset.org/abstracts/109933/design-of-an-ensemble-learning-behavior-anomaly-detection-framework" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109933.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">44</span> Enhancement of Dune Sand from the Western Erg (Algeria) in the Formulation of New Concrete</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Tafraoui">Ahmed Tafraoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilles%20Escadeillas"> Gilles Escadeillas</a>, <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Vidal"> Thierry Vidal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The southern Algeria is known for its huge sand dunes that cover part of its territory (Sahara). This sand has features that allow a glimpse of a recovery in the construction field in the form of Ultra High Performance Concrete (UHPC). This type of concrete using a large amount of silica fume, ultra fine addition that gives very high performance but is also relatively rare and expensive. Replacing it with another addition to equivalent properties, such as metakaolin, can also be considered. The objective of this study is to both enhance the sand dunes of Erg south west western Algeria but also reduce manufacturing costs of Ultra High Performance Concrete to incorporating metakaolin to instead of silica fume. Performances to determine mechanical performance are instantaneous, compression and bending. Initially, we characterized the Algerian sand dune. Then, we have to find a formulation of UHPC, adequate in terms of implementation and to replace silica fume by metakaolin. Finally, we studied the actual value of the sand dune. Concrete obtained have very high mechanical performance, up to a compressive strength of 250 MPa, a tensile strength of 45 MPa by bending with the method of heat treatment. This study shows that the enhancement of dune sand studied is quite possible in UHPC, and in particular UHPC bundles and the replacement of silica fume by metakaolin do not alter the properties of these concretes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ultra%20High%20Performance%20Concrete" title="Ultra High Performance Concrete">Ultra High Performance Concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=sand%20dune" title=" sand dune"> sand dune</a>, <a href="https://publications.waset.org/abstracts/search?q=formulations" title=" formulations"> formulations</a>, <a href="https://publications.waset.org/abstracts/search?q=silica%20fume" title=" silica fume"> silica fume</a>, <a href="https://publications.waset.org/abstracts/search?q=metakaolin" title=" metakaolin"> metakaolin</a>, <a href="https://publications.waset.org/abstracts/search?q=strength" title=" strength"> strength</a> </p> <a href="https://publications.waset.org/abstracts/21852/enhancement-of-dune-sand-from-the-western-erg-algeria-in-the-formulation-of-new-concrete" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21852.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">471</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">43</span> Mathematics Anxiety and Attitude among Nigerian University Library and Information Science Undergraduate Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fredrick%20Olatunji%20Ajegbomogun">Fredrick Olatunji Ajegbomogun</a>, <a href="https://publications.waset.org/abstracts/search?q=Clement%20Ola%20Adekoya"> Clement Ola Adekoya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mathematics has, for ages, been an essential subject in the education curriculum across the globe. The word mathematics scares the majority of undergraduate students and even more library and information science (LIS) students who have not seen the pertinence of the subject to their academic pursuits. This study investigated mathematics anxiety and attitudes among LIS undergraduate students in Nigerian universities. The study adopted a descriptive survey research design. Multi-stage and convenient sampling techniques were used for the study. Data were collected using a questionnaire and analyzed using descriptive statistical tools. It was found that mathematics is important in LIS education. The students displayed a high level of anxiety toward mathematics. The students have a negative attitude toward mathematics. However, the hypotheses tested revealed that while the LIS female undergraduate students displayed low levels of anxiety and a positive attitude toward mathematics, the level of anxiety of the male undergraduate students was high, and their attitude toward mathematics was negative. It was recommended that LIS undergraduate students develop a positive attitude towards mathematics and appreciate that the paradigm shift in the practice of librarianship is towards mathematics as a way of developing technological tools (hardware and software) to facilitate the effective delivery of library services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anxiety" title="anxiety">anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=attitude" title=" attitude"> attitude</a>, <a href="https://publications.waset.org/abstracts/search?q=library%20and%20information%20science" title=" library and information science"> library and information science</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematics%20anxiety" title=" mathematics anxiety"> mathematics anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=undergraduate%20students" title=" undergraduate students"> undergraduate students</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigerian%20universities" title=" Nigerian universities"> Nigerian universities</a> </p> <a href="https://publications.waset.org/abstracts/150160/mathematics-anxiety-and-attitude-among-nigerian-university-library-and-information-science-undergraduate-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150160.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">157</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">42</span> Nutritive Value of Three-Stage Olive Cake (Olea europaea L.) for Growing Rabbit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahia%20Dorbane">Zahia Dorbane</a>, <a href="https://publications.waset.org/abstracts/search?q=Si%20Ammar%20Kadi"> Si Ammar Kadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Dalila%20Boudouma"> Dalila Boudouma</a>, <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Gidenne"> Thierry Gidenne</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In rabbits feeding, minimum fibre intake is essential to avoid digestive disorders. However, this concentration of fibre is not easy to obtain when formulating feeds, without reduction of nutritional value. Three stage olive cake, the residual material after oil extraction by centrifugation, including pulp and stones, can be used as a fibre source in rabbit diet. The incorporation of olive cake can allow a better balance between different fibre fractions and reduce health disorder. However, for practical use of any raw material, it is necessary to know its chemical and nutritive value. The aim of this study was to assess the nutritive value of three-stage olive cake (TSOC) for growing rabbits. Thus, 36 rabbits weaned at 35 days (702.8 ± 28.5) were divided into three groups of 12 receiving one of the following diets: control with 0% of TSOC, TSOC10 (10% of TSOC) and TSOC20 (20% TSOC). The rabbits were individually housed in digestibility cages and received ad libitum one of the three diets, fresh and clean water was provided ad libitum. After an adaptation period of 7d, feces were collected for 4d. Collected feces were frozen and stored for further analysis. The chemical composition of TSOC shows that it is a rich fiber raw material since it contains (%DM): 6% of CP; 7.4% of EE; 78.7% of NDF; 55.4% of ADF and 24.3% of ADL. The inclusion of TSOC at 20% of basal diet reduced the digestibility coefficient of organic matter, crude protein and NDF from 67.8 to 55.3%, 80.4 to 75.3% and from 31.5 to 18.4% (p < 0.001) respectively. The digestible energy and digestible protein content of the three-stage olive cake estimated by regression was 2.94 ± 0.52MJ DE/kg DM and 22.4 ± 6 g DP/kg DM respectively. In conclusion, based on the results of the present experiment, the three-stage olive cake can be used as a fibre source for rabbit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digestibility" title="digestibility">digestibility</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritive%20value" title=" nutritive value"> nutritive value</a>, <a href="https://publications.waset.org/abstracts/search?q=olive%20cake" title=" olive cake"> olive cake</a>, <a href="https://publications.waset.org/abstracts/search?q=rabbit" title=" rabbit"> rabbit</a> </p> <a href="https://publications.waset.org/abstracts/106579/nutritive-value-of-three-stage-olive-cake-olea-europaea-l-for-growing-rabbit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106579.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">156</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">41</span> Borassus aethiopum Mart Mature Fruits Macro-Composition, Drying Temperature Effect on Its Pulp Protein, Fat, Sugars, Metabolizable Energy, and Fatty Acids Profile</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tagouelbe%20Tiho">Tagouelbe Tiho</a>, <a href="https://publications.waset.org/abstracts/search?q=Amissa%20Augustin%20Adima"> Amissa Augustin Adima</a>, <a href="https://publications.waset.org/abstracts/search?q=Yao%20Casimir%20Brou"> Yao Casimir Brou</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabayo%20Traore"> Nabayo Traore</a>, <a href="https://publications.waset.org/abstracts/search?q=Gouha%20Firmin%20Kouassi"> Gouha Firmin Kouassi</a>, <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Roland%20Kouame"> Thierry Roland Kouame</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryline%20Kouba"> Maryline Kouba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The work aimed to study Borassus aethiopum Mart (B.a) dried pulp nutritional value for its incorporation in human and poultry diets. Firstly, the mature fruit macro-composition was assessed. Secondly, the pulp was dried at 40, 50, 60, 70, and 80ᵒC. Thereafter, the analysis was performed for fat, protein, total sugars, Ca, P, Mg, and fatty acid profile monitoring. As a result, the fruits weighed 1,591.35, delivered 516.73, and 677.82 grams of pulp and seeds, respectively. Mainly, increasing heat adversely affected the outputs. Consequently, the fat results were 14.12, 12.97, 8.93, 8.89ᶜ, and 5.56%; protein contents were 11.64, 10.15, 8.97, 8.84, and 8.42%; total sugar deliveries were 6.28, 6.05, 5.26, 5.02, and 4.76% (P < 0.01). Thereafter, the metabolizable energies were 3,785.22; 3,834.28; 3,616.62; 3,667.03; and 3,608.33 kcal/kg (DM). Additionally, Calcium (Ca) contents were 0.51, 0.55, 0.69, 0.77, and 0.81%, while phosphorus (P) mean was 0.17%, and the differences were not significant (P < 0.01). So, the Ca/P ratios were 2.79, 3.04, 4.10, 4.71, and 4.95. Finally, fatty acids (FA) assessments revealed 22.33 saturated (SFA), 77.67 unsaturated (UFA), within which 67.59% were monounsaturated (MUFA). Interestingly, the rising heat depressed n-6/n-3 ratios that were 1.1, 1.1, 0.45 and 0.38, respectively at 40, 50, 70 and 80ᵒC. In short, drying did not only enhance the product shelf life but it also improved the nutritional value. Thus, B.a mature fruit pulps dried at 70ᵒC are good functional foods, with more than 66% MUFA, and energy source for human and poultry nutrition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Borassus%20aethiopum%20Mart" title="Borassus aethiopum Mart">Borassus aethiopum Mart</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acids" title=" fatty acids"> fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolizable%20energy" title=" metabolizable energy"> metabolizable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=minerals" title=" minerals"> minerals</a>, <a href="https://publications.waset.org/abstracts/search?q=protein" title=" protein"> protein</a> </p> <a href="https://publications.waset.org/abstracts/91972/borassus-aethiopum-mart-mature-fruits-macro-composition-drying-temperature-effect-on-its-pulp-protein-fat-sugars-metabolizable-energy-and-fatty-acids-profile" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91972.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">171</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">40</span> Analyzing the Performance of Machine Learning Models to Predict Alzheimer's Disease and its Stages Addressing Missing Value Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Theran">Carlos Theran</a>, <a href="https://publications.waset.org/abstracts/search?q=Yohn%20Parra%20Bautista"> Yohn Parra Bautista</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Adankai"> Victor Adankai</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Alo"> Richard Alo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jimwi%20Liu"> Jimwi Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Clement%20G.%20Yedjou"> Clement G.

In 2016 an estimated 40 million were diagnosed with AD, and for 2050 is expected to reach 131 million people affected by AD. Therefore, detecting and confirming AD at its different stages is a priority for medical practices to provide adequate and accurate treatments. Recently, Machine Learning (ML) models have been used to study AD's stages handling missing values in multiclass, focusing on the delineation of Early Mild Cognitive Impairment (EMCI), Late Mild Cognitive Impairment (LMCI), and normal cognitive (CN). But, to our best knowledge, robust performance information of these models and the missing data analysis has not been presented in the literature. In this paper, we propose studying the performance of five different machine learning models for AD's stages multiclass prediction in terms of accuracy, precision, and F1-score. Also, the analysis of three imputation methods to handle the missing value problem is presented. A framework that integrates ML model for AD's stages multiclass prediction is proposed, performing an average accuracy of 84%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alzheimer%27s%20disease" title="alzheimer's disease">alzheimer's disease</a>, <a href="https://publications.waset.org/abstracts/search?q=missing%20value" title=" missing value"> missing value</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=performance%20evaluation" title=" performance evaluation"> performance evaluation</a> </p> <a href="https://publications.waset.org/abstracts/147485/analyzing-the-performance-of-machine-learning-models-to-predict-alzheimers-disease-and-its-stages-addressing-missing-value-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147485.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">251</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">39</span> Influence of Valve Lift Timing on Producer Gas Combustion and Its Modeling Using Two-Stage Wiebe Function</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Sreedhar%20Babu">M.

Unlike the conventional hydrocarbon fuels (Gasoline and Natural gas), the combustion properties of producer gas fuel are much different. Therefore, setting of optimal spark time for efficient engine operation is required. Owing to the fluctuating tendency of producer gas composition during gasification process, the heat release patterns (dictating the power output and emissions) obtained are quite different from conventional fuels. It was found that, valve lift timing is yet another factor which influences the burn rate of producer gas fuel, and thus, the heat release rate of the engine. Therefore, the present study was motivated to estimate the influence of valve lift timing analytically (Wiebe model) on the burn rate of producer gas through curve fitting against experimentally obtained mass fraction burn curves of several producer gas compositions. Furthermore, Wiebe models are widely used in zero-dimensional codes for engine parametric studies and are quite popular. This study also addresses the influence of hydrogen and methane concentration of producer gas on combustion trends, which are known to cause dynamics in engine combustion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=combustion%20duration%20%28CD%29" title="combustion duration (CD)">combustion duration (CD)</a>, <a href="https://publications.waset.org/abstracts/search?q=crank%20angle%20%28CA%29" title=" crank angle (CA)"> crank angle (CA)</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20fraction%20burnt%20%28MFB%29" title=" mass fraction burnt (MFB)"> mass fraction burnt (MFB)</a>, <a href="https://publications.waset.org/abstracts/search?q=producer%20sas%20%28PG%29" title=" producer sas (PG)"> producer sas (PG)</a>, <a href="https://publications.waset.org/abstracts/search?q=Wiebe%20Combustion%20Model%20%28WCM%29" title=" Wiebe Combustion Model (WCM)"> Wiebe Combustion Model (WCM)</a>, <a href="https://publications.waset.org/abstracts/search?q=wide%20open%20throttle%20%28WOT%29" title=" wide open throttle (WOT)"> wide open throttle (WOT)</a> </p> <a href="https://publications.waset.org/abstracts/64730/influence-of-valve-lift-timing-on-producer-gas-combustion-and-its-modeling-using-two-stage-wiebe-function" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64730.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">311</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">38</span> Assessment of ASEI-PDSI Method on Students’ Attitude and Achievement in Junior Secondary Schools Mathematics in FCT-Abuja</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amenaghawon%20Clement%20Osemwinyen">Amenaghawon Clement Osemwinyen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Activity, Student-centred, Experiment, Improvisation - Plan, Do, See, Improve (ASEI-PDSI) method championed by the Strengthening Mathematics And Science Education (SMASE) - Nigeria Project is an attempt to improve the quality of mathematics, which has consistently declined over the years in both public primary and secondary schools across the country. The study thus assessed the ASEI-PDSI method on students’ attitudes and achievement in junior secondary schools (JSS) mathematics in FCT-Abuja. A survey research design was adopted, and 100 mathematics teachers using a stratified random sampling method were used for the study. The data were collected using structured questionnaires and analyzed using descriptive statistics. The findings showed that the ASEI-PDSI method had significantly improved the attitudes of students toward mathematics. The study also revealed that the ASEI-PDSI method significantly influenced junior secondary school (JSS) students’ mathematics achievement. Amongst the recommendations were that teachers should be encouraged to adopt the ASEI-PDSI method in teaching and learning mathematics in order to create a mathematically stimulating classroom environment which could advertently influence junior secondary school (JSS) students’ attitude and academic performance in mathematics. Also, regular in-service training programs should be organized by stakeholders (government and other interest groups) so as to improve the teaching strategies of teachers, mostly as they affect the ASEI-PDSI method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=achievement" title="achievement">achievement</a>, <a
