great potential and development opportunities. Researchers are focusing on optimization in many fields like efficient deployment and routing protocols. In this article, we will concentrate on energy efficiency for WSN because WSN nodes are habitually deployed in severe No Man鈥檚 Land with batteries are not rechargeable, so reducing energy consumption represents an important challenge to extend the life of the network. We will present the design of new WSN mote based on ultra low power STM32L microcontrollers and the ZIGBEE transceiver CC2520.

In this context, we propose a method for extracting keyframes from videos based on face quality and deep learning for a face recognition task. This method has two steps. We start by generating face quality scores for each face image based on the use of three face feature extractors, including Gabor, LBP, and HOG. The second step consists in training a Deep Convolutional Neural Network in a supervised manner in order to select the frames that have the best face quality.

Its efficiency directly influences the performance of the whole cloud environment. Finding an effective method to address these critical issues and increase cloud performance was necessary. This paper proposes a mobile agents-based framework for dynamic resource allocation in cloud computing to minimize both the cost of using virtual machines and the makespan. Furthermore, its impact on the best response time and power consumption has been studied.

This friction can also cause damage to the piston material. Thus, the choice of an optimal material for the piston is necessary to improve the elastohydrodynamical contacts of the piston. In this study, to achieve this objective, an elastohydrodynamical lubrication model that satisfies the best tribological behavior of the piston with the optimum choice of material is developed. Several aluminum alloys composed of different components are studied in this simulation. An application is made on the piston 60 x 120 mm Diesel engine type F8L413 currently mounted on Deutz trucks TB230 by using different aluminum alloys where alloys based on aluminum-silicon have better tribological performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EHD%20lubricated%20contacts" title="EHD lubricated contacts">EHD lubricated contacts</a>, <a href="https://publications.waset.org/abstracts/search?q=friction" title=" friction"> friction</a>, <a href="https://publications.waset.org/abstracts/search?q=properties%20of%20materials" title=" properties of materials"> properties of materials</a>, <a href="https://publications.waset.org/abstracts/search?q=tribological%20performance" title=" tribological performance"> tribological performance</a> </p> <a href="https://publications.waset.org/abstracts/49879/enhancement-of-tribological-behavior-for-diesel-engine-piston-of-solid-skirt-by-an-optimal-choice-of-interface-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49879.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">272</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> The Fluid Limit of the Critical Processor Sharing Tandem Queue</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amal%20Ezzidani">Amal Ezzidani</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelghani%20Ben%20Tahar"> Abdelghani Ben Tahar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hanini"> Mohamed Hanini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A sequence of finite tandem queue is considered for this study.

Among these reforms were those dealing with health care, education, as well as social security, which would facilitate accordingly the evolution of the American welfare state. After the New Deal, from 1945 to 1969, American presidents sought to carry out and enlarge the scope of the welfare state that emerged during the Roosevelt Administration by introducing new social reforms. Yet, there were some American presidents who succeeded, and there were some presidents who failed.The task of this research work is to depict the postwar period from 1945 to 1969. Some light will be shed on the main causes that led to the delay of many programs from 1945 to 1960. Further, the focus will be on the main factors that contributed to the reappearance of many social reforms and the dramatic expansion of the welfare state all along the 1960s. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=new%20deal" title="new deal">new deal</a>, <a href="https://publications.waset.org/abstracts/search?q=great%20society" title=" great society"> great society</a>, <a href="https://publications.waset.org/abstracts/search?q=medicaid" title=" medicaid"> medicaid</a>, <a href="https://publications.waset.org/abstracts/search?q=medicare" title=" medicare"> medicare</a>, <a href="https://publications.waset.org/abstracts/search?q=war%20on%20poverty" title=" war on poverty"> war on poverty</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20reforms" title=" social reforms"> social reforms</a>, <a href="https://publications.waset.org/abstracts/search?q=welfare%20reforms" title=" welfare reforms"> welfare reforms</a> </p> <a href="https://publications.waset.org/abstracts/13867/social-reforms-and-the-welfare-state-in-america-after-the-new-deal-1945-1969" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13867.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">458</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> Management of Al-Khaldiyah Road (Al Khobar) in Order to Optimize Safety and Improve Sight View</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amer%20Alsari">Amer Alsari</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Alhalal"> Hassan Alhalal</a>, <a href="https://publications.waset.org/abstracts/search?q=Tahar%20Ayadat"> Tahar Ayadat</a>, <a href="https://publications.waset.org/abstracts/search?q=Andi%20Asiz"> Andi Asiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Omar%20KM%20Ouda"> Omar KM Ouda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Al Khaldiyah is a regional road situated in west-south of Al Khobar, precisely in the area of Half Moon Bay.

From this perspective, we propose to make a contribution to the analysis of the behavior of concrete slabs reinforced with composite fabrics, arranged in parallel folds according to the thickness of the slab. The analysis of experimentally obtained modes of failure confirms, generally, that the ruin of the structure occurs essentially by punching. Accordingly, our work is directed to the analysis of the behavior of reinforced slabs towards the punching. An experimental investigation is realized. For that purpose, a set of trial specimens was made. The reinforced specimens are subjected to an essay of punching, by making vary the direction of the eccentricity. The first experimental results show that the ultimate loads, as well as the transition from the flexion failure mode to the punching failure mode, are governed essentially by the eccentricity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composites" title="composites">composites</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete%20slabs" title=" concrete slabs"> concrete slabs</a>, <a href="https://publications.waset.org/abstracts/search?q=failure" title=" failure"> failure</a>, <a href="https://publications.waset.org/abstracts/search?q=laminate" title=" laminate"> laminate</a>, <a href="https://publications.waset.org/abstracts/search?q=punching" title=" punching"> punching</a> </p> <a href="https://publications.waset.org/abstracts/47009/influence-of-the-eccentricity-of-a-concentrated-load-on-the-behavior-of-multilayers-slabs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47009.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">239</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> Prediction of the Behavior of 304L Stainless Steel under Uniaxial and Biaxial Cyclic Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aboussalih%20Amira">Aboussalih Amira</a>, <a href="https://publications.waset.org/abstracts/search?q=Zarza%20Tahar"> Zarza Tahar</a>, <a href="https://publications.waset.org/abstracts/search?q=Fedaoui%20Kamel"> Fedaoui Kamel</a>, <a href="https://publications.waset.org/abstracts/search?q=Hammoudi%20Saleh"> Hammoudi Saleh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work focuses on the simulation of the prediction of the behaviour of austenitic stainless steel (SS) 304L under complex loading in stress and imposed strain.

First, we represent the evolution of the axial stress as a function of the plastic strain through hysteresis loops revealing a hardening behaviour caused by the increase in stress by stress in the direction of tension/compression. In a second step, the study of the ratcheting phenomenon takes a key place in this work by the appearance of the average stress.

The results reveal the apparition of 伪-AlFeSi, 伪-AlFe(Mn)Si type precipitates frequently present and witch remain stable at high temperature in Al-Mg-Si alloys. Indeed, the hardening response in both sheets is certainly due to the predominance of very fine typical phases 尾' and 尾'' as rods and needles developed during aging with and without pre-aging. The effect of pre ageing just after homogenization and quenching is to correct the undesirable effect of aging at ambient temperature by making faster alloy hardening during artificial aging.The addition of 0.10 wt % copper has allowed to refine and to enhance the precipitation hardening after quenching. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AlMgSi%20alloys" title="AlMgSi alloys">AlMgSi alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=precipitation" title=" precipitation"> precipitation</a>, <a href="https://publications.waset.org/abstracts/search?q=hardening" title=" hardening"> hardening</a>, <a href="https://publications.waset.org/abstracts/search?q=activation%20energy" title=" activation energy"> activation energy</a> </p> <a href="https://publications.waset.org/abstracts/166964/precipitation-and-age-hardening-in-al-mg-si-cu-alloys-for-automotive-body-sheet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166964.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">89</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">36</span> Damage to LCP by the Ratcheting Phenomenon Under Cyclic Motion in Oligocyclic Fatigue</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aboussalih%20Amira">Aboussalih Amira</a>, <a href="https://publications.waset.org/abstracts/search?q=Zarza%20Tahar"> Zarza Tahar</a>, <a href="https://publications.waset.org/abstracts/search?q=Fedaoui%20Kamel"> Fedaoui Kamel</a>, <a href="https://publications.waset.org/abstracts/search?q=Baroura%20Lazhar"> Baroura Lazhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hammoudi%20Salah"> Hammoudi Salah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> 316 L steel is a stainless steel frequently used in orthopedic surgery; in the design of implants (hip, knee, shoulder, ankle, etc.), in dental surgery, cardiology, ophthalmology.

The behavior of 316 L steel in low cycle fatigue, under uniaxial cyclic loading of tension/compression, producing significant plastic deformations leading to material damage. This investigation allowed us to characterize the behavior of the 316L steel employed in the locking of the compression plates (LCP), of which they are generally used in orthopedics to stabilize the fractured bone parts. And to perceive the phenomenon of Ratcheting leading to the damage of LCP by an excess of plastic deformation under nonsymmetrical alternated imposed constraint in low cycle fatigue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=316L%20SS" title="316L SS">316L SS</a>, <a href="https://publications.waset.org/abstracts/search?q=locking%20compression%20plate" title=" locking compression plate"> locking compression plate</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20cycle%20fatigue" title=" low cycle fatigue"> low cycle fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=ratcheting" title=" ratcheting"> ratcheting</a> </p> <a href="https://publications.waset.org/abstracts/182140/damage-to-lcp-by-the-ratcheting-phenomenon-under-cyclic-motion-in-oligocyclic-fatigue" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182140.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">63</span> </span> </div> </div> <ul class="pagination"> <li class="page-item disabled"><span class="page-link">&lsaquo;</span></li> <li class="page-item active"><span class="page-link">1</span></li> <li class="page-item"><a class="page-link" href="https://publications.waset.org/abstracts/search?q=Tahar%20Ezzeddine&amp;page=2">2</a></li> <li class="page-item"><a class="page-link" href="https://publications.waset.org/abstracts/search?q=Tahar%20Ezzeddine&amp;page=3">3</a></li> <li class="page-item"><a class="page-link" href="https://publications.waset.org/abstracts/search?q=Tahar%20Ezzeddine&amp;page=2" rel="next">&rsaquo;</a></li> </ul> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">&copy;
