A time history analysis is used to determine the response of the structure in terms of relative displacement and understory drift at various levels of the building. Thus, the results show that the efficiency of the isolator increases with the assumed damping ratio, provided that this latter is less or equal to 20%. Beyond this value, the isolator becomes less convenient.

However, it presents various challenges that need to be addressed in order to be efficiently utilized. The resources provisioning problem for workflow applications has been widely studied. Nevertheless, the existing works did not consider the change in workflow instances while they are being executed. This functionality has become a major requirement to deal with unusual situations and evolution. This paper presents a first step towards the resources provisioning for a dynamic workflow. In fact, we propose a provisioning algorithm which minimizes the overall workflow execution cost, while meeting a deadline constraint. Then, we extend it to support the dynamic adding of tasks. Experimental results show that our proposed heuristic demonstrates a significant reduction in resources cost by using a consolidation process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title="cloud computing">cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=resources%20provisioning" title=" resources provisioning"> resources provisioning</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20workflow" title=" dynamic workflow"> dynamic workflow</a>, <a href="https://publications.waset.org/abstracts/search?q=workflow%20applications" title=" workflow applications"> workflow applications</a> </p> <a href="https://publications.waset.org/abstracts/19467/towards-a-resources-provisioning-for-dynamic-workflows-in-the-cloud" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19467.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">295</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">1665</span> Modeling of Hydrogen Production by Inductively Coupled Methane Plasma for Input Power Pin=700W</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelatif%20Gadoum">Abdelatif Gadoum</a>, <a href="https://publications.waset.org/abstracts/search?q=Djilali%20Benyoucef"> Djilali Benyoucef</a>, <a href="https://publications.waset.org/abstracts/search?q=Mouloudj%20Hadj"> Mouloudj Hadj</a>, <a href="https://publications.waset.org/abstracts/search?q=Alla%20Eddine%20Toubal%20Maamar"> Alla Eddine Toubal Maamar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Habib%20Allah%20%20Lahoual"> Mohamed Habib Allah Lahoual</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydrogen occurs naturally in the form of chemical compounds, most often in water and hydrocarbons.

Two structural units are distinguished: a Palaeozoic basement and a Mesozoic cover. The study area is densely faulted and major faults strike N110° to N140° and dip vertically The mineralized fault zones are readily distinguishable by their argillic wall rock alteration. The fault zones that are filled with mineralizations, aplites, microgranites and quartz run roughly parallel to each other and are apparently in the same fault system. The Palaeozoic basement rocks contain mineralization occurring as veins, veinlets and disseminations. The Liassic carbonate platform sequence contains Ba (Pb-Zn) sulphide deposits occurring mainly as strata bound, and open space filling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Algeria" title="Algeria">Algeria</a>, <a href="https://publications.waset.org/abstracts/search?q=basement" title=" basement"> basement</a>, <a href="https://publications.waset.org/abstracts/search?q=Beni%20Snouss" title=" Beni Snouss"> Beni Snouss</a>, <a href="https://publications.waset.org/abstracts/search?q=cover" title=" cover"> cover</a> </p> <a href="https://publications.waset.org/abstracts/41823/geological-characteristics-of-the-beni-snouss-district" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41823.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">283</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">1663</span> Optimization of Extraction Conditions for Phenolic Compounds from Deverra Scoparia Coss and Dur</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roukia%20Hammoudi">Roukia Hammoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Chabrouk%20Farid"> Chabrouk Farid</a>, <a href="https://publications.waset.org/abstracts/search?q=Dehak%20Karima"> Dehak Karima</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahfoud%20Hadj%20Mahammed"> Mahfoud Hadj Mahammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Didi%20Ouldelhadj"> Mohamed Didi Ouldelhadj</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study was to optimise the extraction conditions for phenolic compounds from Deverra scoparia Coss and Dur.

The more sensitive the information, such as credit card data, personal medical information or personal emails being processed by mobile application, the more important it is to ensure the confidentiality of this information. Monitoring non-trusted mobile application during execution in an environment where sensitive information is present is difficult and unnerving.

Recently, re-identifying people over large public cameras networks has become a crucial task of great importance to ensure public security. The vision community has deeply investigated this area of research. Most existing researches rely only on the spatial appearance information from either one or multiple person images. Actually, the real person re-id framework is a multi-shot scenario. However, to efficiently model a person’s appearance and to choose the best samples to remain a challenging problem. In this work, an extensive comparison of descriptors of state of the art associated with the proposed frame selection method is studied. Specifically, we evaluate the samples selection approach using multiple proposed descriptors. We show the effectiveness and advantages of the proposed method by extensive comparisons with related state-of-the-art approaches using two standard datasets PRID2011 and iLIDS-VID. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=camera%20network" title="camera network">camera network</a>, <a href="https://publications.waset.org/abstracts/search?q=descriptor" title=" descriptor"> descriptor</a>, <a href="https://publications.waset.org/abstracts/search?q=model" title=" model"> model</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-shot" title=" multi-shot"> multi-shot</a>, <a href="https://publications.waset.org/abstracts/search?q=person%20re-identification" title=" person re-identification"> person re-identification</a>, <a href="https://publications.waset.org/abstracts/search?q=selection" title=" selection"> selection</a> </p> <a href="https://publications.waset.org/abstracts/65815/images-selection-and-best-descriptor-combination-for-multi-shot-person-re-identification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65815.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">278</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">1659</span> Direct Measurements of the Electrocaloric Effect in Solid Ferroelectric Materials via Thermoreflectance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Layla%20Farhat">Layla Farhat</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathieu%20Bardoux"> Mathieu Bardoux</a>, <a href="https://publications.waset.org/abstracts/search?q=St%C3%A9phane%20Longuemart"> Stéphane Longuemart</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziad%20Herro"> Ziad Herro</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhak%20Hadj%20Sahraoui"> Abdelhak Hadj Sahraoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrocaloric (EC) effect refers to the isothermal entropy or adiabatic temperature changes of a dielectric material induced by an external electric field.

Milk production of does was measured every day during the days following 215 parturitions. It was estimated by weighing the female before and after the single daily suckling (10–15 min between the two weighing operations). The various calculated parameters were the quantity of milk produced per day, per week and the total quantity produced in 21 days, as well as the intake of milk by young rabbits. The analysis concerned the effects of the number of successive litters (3 classes: 1 to 3 and more) and of the average number of the number of young rabbits suckled per litter (6 classes: from 1-2 kits to more than 6). During the 21 days of controlled lactation, the average litter size was 6±3. The rabbits of the Aures area produced on average 2544.34±747 g in 21 days that is 121 g of milk/day or 21 g of milk/kit/day. The milk yield increased from 526, 1035, 1240 and 2801 g to 760, 1365, 1715 and 3840 for week 1, 2, 3 and the total period of lactation, respectively. Nevertheless, milk production available per kit and per day decreased linearly with kits number in the litter for each of the 3 weeks considered. On the other hand the milk yield was not affected by the weight at birth of kits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=milk%20production" title="milk production">milk production</a>, <a href="https://publications.waset.org/abstracts/search?q=litter%20size" title=" litter size"> litter size</a>, <a href="https://publications.waset.org/abstracts/search?q=rabbit" title=" rabbit"> rabbit</a>, <a href="https://publications.waset.org/abstracts/search?q=Aures%20area" title=" Aures area"> Aures area</a>, <a href="https://publications.waset.org/abstracts/search?q=Algeria" title=" Algeria"> Algeria</a> </p> <a href="https://publications.waset.org/abstracts/4924/evaluation-of-milk-production-of-an-algerian-rabbit-population-raised-in-aures-area" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4924.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">264</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">1657</span> Liquid-Liquid Extraction of Uranium (VI) from Aqueous Solution Using 1-Hydroxyalkylidene-1,1-Diphosphonic Acids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustapha%20Bouhoun%20Ali">Mustapha Bouhoun Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Yacine%20Badjah%20Hadj%20Ahmed"> Ahmed Yacine Badjah Hadj Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mouloud%20Attou"> Mouloud Attou</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdel%20Hamid%20Elias"> Abdel Hamid Elias</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Amine%20Didi"> Mohamed Amine Didi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The extraction of uranium(VI) from aqueous solutions has been investigated using 1-hydroxyhexadecylidene-1,1-diphosphonic acid (HHDPA) and 1-hydroxydodecylidene-1,1-diphosphonic acid (HDDPA), which were synthesized and characterized by elemental analysis and by FT-IR, 1H NMR, 31P NMR spectroscopy. In this paper, we propose a tentative assignment for the shifts of those two ligands and their specific complexes with uranium(VI). We carried out the extraction of uranium(VI) by HHDPA and HDDPA from [carbon tetrachloride + 2-octanol (v/v: 90%/10%)] solutions. Various factors such as contact time, pH, organic/aqueous phase ratio and extractant concentration were considered. The optimum conditions obtained were: contact time = 20 min, organic/aqueous phase ratio = 1, pH value = 3.0 and extractant concentration = 0.3M. The extraction yields are more significant in the case of the HHDPA which is equipped with a hydrocarbon chain, longer than that of the HDDPA. Logarithmic plots of the uranium(VI) distribution ratio vs. pHeq and the extractant concentration showed that the ratio of extractant to extracted uranium(VI) (ligand/metal) is 2:1. The formula of the complex of uranium(VI) with the HHDPA and the DHDPA is UO2(H3L)2 (HHDPA and DHDPA are denoted as H4L). A spectroscopic analysis has showed that coordination of uranium(VI) takes place via oxygen atoms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=liquid-liquid%20extraction" title="liquid-liquid extraction">liquid-liquid extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=uranium%28VI%29" title=" uranium(VI)"> uranium(VI)</a>, <a href="https://publications.waset.org/abstracts/search?q=1-hydroxyalkylidene-1" title=" 1-hydroxyalkylidene-1"> 1-hydroxyalkylidene-1</a>, <a href="https://publications.waset.org/abstracts/search?q=1-diphosphonic%20acids" title="1-diphosphonic acids">1-diphosphonic acids</a>, <a href="https://publications.waset.org/abstracts/search?q=HHDPA" title=" HHDPA"> HHDPA</a>, <a href="https://publications.waset.org/abstracts/search?q=HDDPA" title=" HDDPA"> HDDPA</a>, <a href="https://publications.waset.org/abstracts/search?q=aqueous%20solution" title=" aqueous solution"> aqueous solution</a> </p> <a href="https://publications.waset.org/abstracts/18650/liquid-liquid-extraction-of-uranium-vi-from-aqueous-solution-using-1-hydroxyalkylidene-11-diphosphonic-acids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18650.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">528</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">1656</span> Evaluation of Total Antioxidant Activity (TAC) of Copper Oxide Decorated Reduced Graphene Oxide (CuO-rGO) at Different Stirring time</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aicha%20Bensouici">Aicha Bensouici</a>, <a href="https://publications.waset.org/abstracts/search?q=Assia%20Mili"> Assia Mili</a>, <a href="https://publications.waset.org/abstracts/search?q=Naouel%20Rdjem"> Naouel Rdjem</a>, <a href="https://publications.waset.org/abstracts/search?q=Nacera%20Baali"> Nacera Baali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Copper oxide decorated reduced graphene oxide (GO) was obtained successfully using two steps route synthesis was used.

However, coherence can be degraded by various factors such as temporal decorrelation, atmospheric disturbances, and geometric misalignments, limiting the reliability of InSAR measurements (Omar Hadj‐Sahraoui and al. 2019). To address this challenge, we propose an innovative hybrid approach that combines artificial intelligence (AI) with advanced filtering techniques to optimize interferometric coherence in InSAR data. Specifically, we introduce a Convolutional Neural Network (CNN) integrated with the Lee filter to enhance the performance of radar interferometry. This hybrid method leverages the strength of CNNs to automatically identify and mitigate the primary sources of decorrelation, while the Lee filter effectively reduces speckle noise, improving the overall quality of interferograms. We develop a deep learning-based model trained on multi-temporal and multi-frequency SAR datasets, enabling it to predict coherence patterns and enhance low-coherence regions. This hybrid CNN-SAR with Lee filtering significantly reduces noise and phase unwrapping errors, leading to more precise deformation maps. Experimental results demonstrate that our approach improves coherence by up to 30% compared to traditional filtering techniques, making it a robust solution for challenging scenarios such as urban environments, vegetated areas, and rapidly changing landscapes. Our method has potential applications in geohazard monitoring, urban planning, and environmental studies, offering a new avenue for enhancing InSAR data reliability through AI-powered optimization combined with robust filtering techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CNN-SAR" title="CNN-SAR">CNN-SAR</a>, <a href="https://publications.waset.org/abstracts/search?q=Lee%20Filter" title=" Lee Filter"> Lee Filter</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20optimization" title=" hybrid optimization"> hybrid optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=coherence" title=" coherence"> coherence</a>, <a href="https://publications.waset.org/abstracts/search?q=InSAR%20phase%20unwrapping" title=" InSAR phase unwrapping"> InSAR phase unwrapping</a>, <a href="https://publications.waset.org/abstracts/search?q=speckle%20noise%20reduction" title=" speckle noise reduction"> speckle noise reduction</a> </p> <a href="https://publications.waset.org/abstracts/193156/hybrid-cnn-sar-and-lee-filtering-for-enhanced-insar-phase-unwrapping-and-coherence-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193156.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">11</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">1651</span> Inhouse Inhibitor for Mitigating Corrosion in the Algerian Oil and Gas Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadjer%20Didouh">Hadjer Didouh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hadj%20Meliani"> Mohamed Hadj Meliani</a>, <a href="https://publications.waset.org/abstracts/search?q=Izzeddine%20Sameut%20Bouhaik"> Izzeddine Sameut Bouhaik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As global demand for natural gas intensifies, Algeria is increasing its production to meet this rising need, placing significant strain on the nation's extensive pipeline infrastructure. Sonatrach, Algeria's national oil and gas company, faces persistent challenges from metal corrosion, particularly microbiologically influenced corrosion (MIC), leading to substantial economic losses. This study investigates the corrosion-inhibiting properties of Calotropis procera extracts, known as karanka, as a sustainable alternative to conventional inhibitors, which often pose environmental risks. The Calotropis procera extracts were evaluated for their efficacy on carbon steel API 5L X52 through electrochemical techniques, including potentiodynamic polarization and electrochemical impedance spectroscopy (EIS), under simulated operational conditions at varying concentrations, particularly at 10%, and elevated temperatures up to 60°C. The results demonstrated remarkable inhibition efficiency, achieving 96.73% at 60°C, attributed to the formation of a stable protective film on the metal surface that suppressed anodic and cathodic corrosion reactions. Scanning electron microscopy (SEM) confirmed the stability and adherence of these protective films, while EIS analysis indicated a significant increase in charge transfer resistance, highlighting the extract's effectiveness in enhancing corrosion resistance. The abundant availability of Calotropis procera in Algeria and its low-cost extraction processes present a promising opportunity for sustainable biocorrosion management strategies in the oil and gas industry, reinforcing the potential of plant-based extracts as viable alternatives to synthetic inhibitors for environmentally friendly corrosion control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion%20inhibition" title="corrosion inhibition">corrosion inhibition</a>, <a href="https://publications.waset.org/abstracts/search?q=calotropis%20procera" title=" calotropis procera"> calotropis procera</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiologically%20influenced%20corrosion" title=" microbiologically influenced corrosion"> microbiologically influenced corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=eco-friendly%20inhibitor" title=" eco-friendly inhibitor"> eco-friendly inhibitor</a> </p> <a href="https://publications.waset.org/abstracts/191069/inhouse-inhibitor-for-mitigating-corrosion-in-the-algerian-oil-and-gas-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191069.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">25</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">1650</span> Isolation and Molecular Identification of Two Fungal Strains Capable of Degrading hydrocarbon Contaminants on Saudi Arabian Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amr%20A.%20EL%20Hanafy">Amr A.

Demagnetization fault means that the strengths of permanent magnets (PM) in PMSM decrease, and it causes low output torque, which is undesirable for EVs. The fault is caused by physical damage, high-temperature stress, inverse magnetic field, and aging. Motor current signature analysis (MCSA) is a conventional motor fault detection method based on the extraction of signal features from stator current. a simulation model of the PMSM under partial demagnetization and uniform demagnetization fault was established, and different degrees of demagnetization fault were simulated. The harmonic analyses using the Fast Fourier Transform (FFT) show that the fault diagnosis method based on the harmonic wave analysis is only suitable for partial demagnetization fault of the PMSM and does not apply to uniform demagnetization fault of the PMSM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet" title="permanent magnet">permanent magnet</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=demagnetization" title=" demagnetization"> demagnetization</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a> </p> <a href="https://publications.waset.org/abstracts/182275/modelling-and-detecting-the-demagnetization-fault-in-the-permanent-magnet-synchronous-machine-using-the-current-signature-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182275.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">68</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">1639</span> Cutaneous Crohn’s Disease in a Child: Atypical Axillary Involvement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Al%20Yousef">A.
