study of the capacity reuse of dredged sediments and treated sediments with lime or cement were used in an establishment layer and the base layer of the roadway. Also, the analysis of mineral changes caused by the addition of lime or cement on the way as described in the mechanical results of stabilised sediments. After determining the quantity of lime and cement required to stabilise the sediment, the compaction characteristics were studied using the modified Proctor method. Then the evolution of the three parameters, that is, ideal water content and maximum dry density had been determined. Mechanical exhibitions can be assessed across the resistance to compression, flexibility modulus and the resistance under traction. The resistance of the formulation treated with cement addition (ROLAC庐645) increase with the quantity of ROLAC庐645. Traction resistances and the elastic modulus were utilized to assess the potential of the formulation as road construction materials utilizing classification diagram. The results show the various formulations with ROLAC庐 645may be employed in subgrades and foundation layers for roads. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cement" title="cement">cement</a>, <a href="https://publications.waset.org/abstracts/search?q=dredged" title=" dredged"> dredged</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment" title=" sediment"> sediment</a>, <a href="https://publications.waset.org/abstracts/search?q=foundation%20layer" title=" foundation layer"> foundation layer</a>, <a href="https://publications.waset.org/abstracts/search?q=resistance" title=" resistance"> resistance</a> </p> <a href="https://publications.waset.org/abstracts/148227/recovery-of-dredged-sediments-with-lime-or-cement-as-platform-materials-for-use-in-a-roadway" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148227.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">99</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">193</span> Design of Organic Inhibitors from Quantum Chemistry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rahma%20Tibigui">Rahma Tibigui</a>, <a href="https://publications.waset.org/abstracts/search?q=Ikram%20Hadj%20Said"> Ikram Hadj Said</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Belkada"> Rachid Belkada</a>, <a href="https://publications.waset.org/abstracts/search?q=Dalila%20Hammoutene"> Dalila Hammoutene</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The vulnerability of industrial facilities is highly concerned with multiple risks from corrosion. The commonly adopted solution is based on the use of organic inhibitors, which are gradually being replaced by environmentally friendly organic inhibitors. In our work, we carried out a quantum chemical study based on the Density Functional Theory (DFT) method at the B3LYP/6-311G (d,p) level of theory. The inhibitory performance of a derivative of the tetrazole molecule has been investigated and reported as a carbon steel-friendly corrosion inhibitor in hydrochloric acid (HCl) medium. The relationship is likely to exist between the molecular structure of this compound as well as its various global reactivity descriptors, and its corrosion inhibition efficiency, which was examined and then discussed. The results show low values of 螖E, which represent strong adsorption of the inhibitor on the steel surface. Moreover, the flat adsorption orientation confirmed the great ability to donate (accept) electrons to (from) steel, fabricating an anchored barrier to prevent steel from corrosion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eco-friendly" title="eco-friendly">eco-friendly</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20inhibitors" title=" corrosion inhibitors"> corrosion inhibitors</a>, <a href="https://publications.waset.org/abstracts/search?q=tetrazole" title=" tetrazole"> tetrazole</a>, <a href="https://publications.waset.org/abstracts/search?q=DFT" title=" DFT"> DFT</a> </p> <a href="https://publications.waset.org/abstracts/169362/design-of-organic-inhibitors-from-quantum-chemistry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169362.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">234</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">192</span> Video Object Segmentation for Automatic Image Annotation of Ethernet Connectors with Environment Mapping and 3D Projection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marrone%20Silverio%20Melo%20Dantas%20Pedro%20Henrique%20Dreyer">Marrone Silverio Melo Dantas Pedro Henrique Dreyer</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriel%20Fonseca%20Reis%20de%20Souza"> Gabriel Fonseca Reis de Souza</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Bezerra"> Daniel Bezerra</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Souza"> Ricardo Souza</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Lins"> Silvia Lins</a>, <a href="https://publications.waset.org/abstracts/search?q=Judith%20Kelner"> Judith Kelner</a>, <a href="https://publications.waset.org/abstracts/search?q=Djamel%20Fawzi%20Hadj%20Sadok"> Djamel Fawzi Hadj Sadok</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The creation of a dataset is time-consuming and often discourages researchers from pursuing their goals. To overcome this problem, we present and discuss two solutions adopted for the automation of this process. Both optimize valuable user time and resources and support video object segmentation with object tracking and 3D projection. In our scenario, we acquire images from a moving robotic arm and, for each approach, generate distinct annotated datasets. We evaluated the precision of the annotations by comparing these with a manually annotated dataset, as well as the efficiency in the context of detection and classification problems. For detection support, we used YOLO and obtained for the projection dataset an F1-Score, accuracy, and mAP values of 0.846, 0.924, and 0.875, respectively. Concerning the tracking dataset, we achieved an F1-Score of 0.861, an accuracy of 0.932, whereas mAP reached 0.894. In order to evaluate the quality of the annotated images used for classification problems, we employed deep learning architectures. We adopted metrics accuracy and F1-Score, for VGG, DenseNet, MobileNet, Inception, and ResNet. The VGG architecture outperformed the others for both projection and tracking datasets. It reached an accuracy and F1-score of 0.997 and 0.993, respectively. Similarly, for the tracking dataset, it achieved an accuracy of 0.991 and an F1-Score of 0.981. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RJ45" title="RJ45">RJ45</a>, <a href="https://publications.waset.org/abstracts/search?q=automatic%20annotation" title=" automatic annotation"> automatic annotation</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20tracking" title=" object tracking"> object tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20projection" title=" 3D projection"> 3D projection</a> </p> <a href="https://publications.waset.org/abstracts/130540/video-object-segmentation-for-automatic-image-annotation-of-ethernet-connectors-with-environment-mapping-and-3d-projection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130540.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">167</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">191</span> Evolution of Bioactive Components of Prickly Pear Juice (Opuntia ficus indica) and Cocktails with Orange Juice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Hadj%20Sadok">T.

The juice from the fruit pulp is characterized by a high pH 5.85 which makes it difficult for its conservation and preservation requires a thermal treatment at high temperatures (over 100 掳C) harmful for bioactive constituents compared to juice orange more acidic and processed at temperatures < 100 掳C. The valuation as fig cocktails-orange is particularly interesting thanks to the contribution of polyph2nols, fiber, vitamin C, reducing sugar (sweetener) and betalaine, minerals while allowing lower temperature processing to decrease pH. The heat treatment of these juices: orange alone or in cocktails showed that the antioxidant power decreases by 12% in presence of 30% of juice treated by the heat and of 28 and 32% in the presence of 10 and 20% juice which shows the effect prickly pear juice of Opuntia. During storage for 4 weeks the loss of vitamin C is 40 and 38% in the presence of 10 and 20% juice and 33% in the presence of 30% pear juice parallel, a treatment of stabilization by heat affects relatively the polyphenols rate which decreases from 10.5% to 30% in the cocktail, and 6.11-6.71pour cocktails at 10% and 20%. Vitamin C decreases to 12 to 24 % after a heat treatment at 85掳C for 30 minutes respectively for the orange juice and pear juice; this reduction is higher when the juice is in the form of cocktails composed of 10 to 30 % pear juice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prickly%20pear%20juice" title="prickly pear juice">prickly pear juice</a>, <a href="https://publications.waset.org/abstracts/search?q=orange%20cocktail" title=" orange cocktail"> orange cocktail</a>, <a href="https://publications.waset.org/abstracts/search?q=polyphenol" title=" polyphenol"> polyphenol</a>, <a href="https://publications.waset.org/abstracts/search?q=Opuntia%20ficus%20indica" title=" Opuntia ficus indica"> Opuntia ficus indica</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin" title=" vitamin"> vitamin</a> </p> <a href="https://publications.waset.org/abstracts/24034/evolution-of-bioactive-components-of-prickly-pear-juice-opuntia-ficus-indica-and-cocktails-with-orange-juice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24034.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">380</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">190</span> Towards a Resources Provisioning for Dynamic Workflows in the Cloud</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fairouz%20Fakhfakh">Fairouz Fakhfakh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hatem%20Hadj%20Kacem"> Hatem Hadj Kacem</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Hadj%20Kacem"> Ahmed Hadj Kacem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cloud computing offers a new model of service provisioning for workflow applications, thanks to its elasticity and its paying model. 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">189</span> Using Deep Learning for the Detection of Faulty RJ45 Connectors on a Radio Base Station</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Djamel%20Fawzi%20Hadj%20Sadok">Djamel Fawzi Hadj Sadok</a>, <a href="https://publications.waset.org/abstracts/search?q=Marrone%20Silv%C3%A9rio%20Melo%20Dantas%20Pedro%20Henrique%20Dreyer"> Marrone Silv茅rio Melo Dantas Pedro Henrique Dreyer</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabriel%20Fonseca%20Reis%20de%20Souza"> Gabriel Fonseca Reis de Souza</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Bezerra"> Daniel Bezerra</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Souza"> Ricardo Souza</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20Lins"> Silvia Lins</a>, <a href="https://publications.waset.org/abstracts/search?q=Judith%20Kelner"> Judith Kelner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A radio base station (RBS), part of the radio access network, is a particular type of equipment that supports the connection between a wide range of cellular user devices and an operator network access infrastructure. Nowadays, most of the RBS maintenance is carried out manually, resulting in a time consuming and costly task. A suitable candidate for RBS maintenance automation is repairing faulty links between devices caused by missing or unplugged connectors. A suitable candidate for RBS maintenance automation is repairing faulty links between devices caused by missing or unplugged connectors. This paper proposes and compares two deep learning solutions to identify attached RJ45 connectors on network ports. We named connector detection, the solution based on object detection, and connector classification, the one based on object classification. With the connector detection, we get an accuracy of 0:934, mean average precision 0:903. Connector classification, get a maximum accuracy of 0:981 and an AUC of 0:989. Although connector detection was outperformed in this study, this should not be viewed as an overall result as connector detection is more flexible for scenarios where there is no precise information about the environment and the possible devices. At the same time, the connector classification requires that information to be well-defined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radio%20base%20station" title="radio base station">radio base station</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance" title=" maintenance"> maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=classification" title=" classification"> classification</a>, <a href="https://publications.waset.org/abstracts/search?q=detection" title=" detection"> detection</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=automation" title=" automation"> automation</a> </p> <a href="https://publications.waset.org/abstracts/130541/using-deep-learning-for-the-detection-of-faulty-rj45-connectors-on-a-radio-base-station" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130541.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">201</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">188</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"> St茅phane Longuemart</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziad%20Herro"> Ziad Herro</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhak%20Hadj%20Sahraoui"> Abdelhak Hadj Sahraoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrocaloric (EC) effect refers to the isothermal entropy or adiabatic temperature changes of a dielectric material induced by an external electric field.

However, coherence can be degraded by various factors such as temporal decorrelation, atmospheric disturbances, and geometric misalignments, limiting the reliability of InSAR measurements (Omar Hadj鈥怱ahraoui 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">183</span> Evolutional Substitution Cipher on Chaotic Attractor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adda%20Ali-Pacha">Adda Ali-Pacha</a>, <a href="https://publications.waset.org/abstracts/search?q=Naima%20Hadj-Said"> Naima Hadj-Said</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, the security of information is primarily founded on the calculation of algorithms that confidentiality depend on the number of bits necessary to define a cryptographic key.

Thus, in this context, we decided to be focused on NK cells and CD14+ monocytes gene expression, considering datasets GSE165461 and GSE198256, respectively. Other datasets with PBMCs, lung, olfactory, and sensory epithelium and lymph were used to provide robust validation for our results. This approach gave an integrated view of the immune responses in COVID-19, pointing out a set of potential biomarkers and therapeutic targets with special regard to standards of physiological conditions. IFI27, MKI67, CENPF, MBP, HBA2, TMEM158, THBD, HBA1, LHFPL2, SLA, and AC104564.3 were identified as key genes from our analysis that have critical biological processes related to inflammation, immune regulation, oxidative stress, and metabolic processes. Consequently, such processes are important in understanding the heterogeneous clinical manifestations of COVID-19鈥攆rom acute to long-term effects now known as 'long COVID'. Subsequent validation with additional datasets consolidated these genes as robust biomarkers with an important role in the diagnosis of COVID-19 and the prediction of its severity. Moreover, their enrichment in key pathophysiological pathways presented them as potential targets for therapeutic intervention.The results provide insight into the molecular dynamics of COVID-19 caused by cells such as NK cells and other monocytes. Thus, this study constitutes a solid basis for targeted diagnostic and therapeutic development and makes relevant contributions to ongoing research efforts toward better management and mitigation of the pandemic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SARS-COV-2" title="SARS-COV-2">SARS-COV-2</a>, <a href="https://publications.waset.org/abstracts/search?q=RNA-seq" title=" RNA-seq"> RNA-seq</a>, <a href="https://publications.waset.org/abstracts/search?q=biomarkers" title=" biomarkers"> biomarkers</a>, <a href="https://publications.waset.org/abstracts/search?q=severity" title=" severity"> severity</a>, <a href="https://publications.waset.org/abstracts/search?q=long%20COVID-19" title=" long COVID-19"> long COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=bio%20analysis" title=" bio analysis"> bio analysis</a> </p> <a href="https://publications.waset.org/abstracts/193566/integrative-transcriptomic-profiling-of-nk-cells-and-monocytes-advancing-diagnostic-and-therapeutic-strategies-for-covid-19" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193566.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">12</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">179</span> Improvement of the Numerical Integration's Quality in Meshless Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahlem%20Mougaida">Ahlem Mougaida</a>, <a href="https://publications.waset.org/abstracts/search?q=Hedi%20Bel%20Hadj%20Salah"> Hedi Bel Hadj Salah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Several methods are suggested to improve the numerical integration in Galerkin weak form for Meshless methods.

Steganalysis is the mechanism of detecting the presence of hidden information in the stego media and it can lead to the prevention of disastrous security incidents.

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. Furthermore, a strong deviation of energy capacity by the LRB (Lead Rubber Bearing) system is recorded. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damping" title="damping">damping</a>, <a href="https://publications.waset.org/abstracts/search?q=base%20isolation" title=" base isolation"> base isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=LRB" title=" LRB"> LRB</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20excitation" title=" seismic excitation"> seismic excitation</a>, <a href="https://publications.waset.org/abstracts/search?q=hysteresis" title=" hysteresis"> hysteresis</a> </p> <a href="https://publications.waset.org/abstracts/14885/characteristics-influencing-response-of-a-base-isolated-building" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14885.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">416</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">176</span> Electric Models for Crosstalk Predection: Analysis and Performance Evaluation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kachout%20Mnaouer">Kachout Mnaouer</a>, <a href="https://publications.waset.org/abstracts/search?q=Bel%20Hadj%20Tahar%20Jamel"> Bel Hadj Tahar Jamel</a>, <a href="https://publications.waset.org/abstracts/search?q=Choubani%20Fethi"> Choubani Fethi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, three electric equivalent models to evaluate crosstalk between three-conductor transmission lines are proposed.

This geometry can be explained by the mechanism of major thrusting in Orbata anticline in the occidental extremity of Gafsa chains, with asymmetrical flank dips and hinge migration kinematics. These kinematics was originally controlled by the Breakthrough structure; the study of this special geometry of gravity flap structure depends on the sedimentation domain, shortening ratios, and erosion speed.

This study aimed to investigate the insecticidal potential of six aqueous (100% water), and methanolic (20/80 (v/v) MeOH/H2O) extracts obtained from aromatic and medicinal plants growing in arid and semi-arid regions of Morocco to control nymphs and adult females of D. opuntiae, under laboratory and greenhouse conditions. Under laboratory conditions, the aqueous extracts of Atriplex halimus at 5% caused significant mortality in nymphs with 71% four days after application and 88%on adult females of D. opuntiae8 days post-treatment. Under greenhouse conditions, the aqueous extract of A. halimus combined with black soap at 10 g/L showed the highest mortality rate of nymphs with 100%, 4 days after application. The adult females' mortality increased significantly to reach 83.75%,14 days after the second application of A. halimus aqueous extract at 5%. Phytochemical analysis of the water extract of A. halimus revealed a high content of saponins (24.09 卤 0.71 mg SSE/g DW) compared to other plant extracts, which was confirmed by LC-MS characterization that showed the presence of 36 triterpenoid saponin compounds (derived from oleic-12-en-28-oic acid), in addition to phytoecdysones, simple carboxylic acids, and flavonoids. These findings showed that using the aqueous extract of A. halimus as a biological pesticide could be incorporated into the management package to control the wild cochineal as a safe alternative to chemical insecticides. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dactylopius%20opuntiae" title="dactylopius opuntiae">dactylopius opuntiae</a>, <a href="https://publications.waset.org/abstracts/search?q=opuntia%20ficus-indica%20L." title=" opuntia ficus-indica L."> opuntia ficus-indica L.</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20extracts" title=" plant extracts"> plant extracts</a>, <a href="https://publications.waset.org/abstracts/search?q=toxicity" title=" toxicity"> toxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=atriplex%20halimus" title=" atriplex halimus"> atriplex halimus</a>, <a href="https://publications.waset.org/abstracts/search?q=saponins" title=" saponins"> saponins</a> </p> <a href="https://publications.waset.org/abstracts/150439/chemical-composition-and-insecticidal-properties-of-moroccan-plant-extracts-against-dactylopius-opuntiae-cockerell-under-laboratory-and-greenhouse-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150439.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">168</span> Infection of Phlebotomus Sergenti with Leishmania Tropica in a Classical Focus of Leishmania Major in Tunisia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kaouther%20Jaouadi">Kaouther Jaouadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jihene%20Bettaieb"> Jihene Bettaieb</a>, <a href="https://publications.waset.org/abstracts/search?q=Amira%20Bennour"> Amira Bennour</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghassen%20Kharroubi"> Ghassen Kharroubi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadok%20Salem"> Sadok Salem</a>, <a href="https://publications.waset.org/abstracts/search?q=Afif%20Ben%20Salah"> Afif Ben Salah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Tunisia, chronic cutaneous leishmaniasis due to Leishmania (L) tropica is an important health problem. Its spreading has not been fully elucidated. Information on sandfly vectors, as well as their associated Leishmania species, is of paramount importance since vector dispersion is one of the major factors responsible for pathogen dissemination. In total, 650 sandflies were captured between June and August 2015 using sticky paper traps in the governorate of Sidi Bouzid, a classical focus of L. major in the Central-West of Tunisia. Polymerase chain reaction-restriction fragment length polymorphism analysis of the internal transcribed spacer 1 and sequencing were used for Leishmania detection and identification. Ninety-seven unfed females were tested for the presence of Leishmania parasite DNA. Six Phlebotomus sergenti were found positive for L. tropica. This finding enhances the understanding of the cycle extension of L. tropica outside its original focus of Tataouine in the South-East of the country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cutaneous%20leishmaniasis" title="cutaneous leishmaniasis">cutaneous leishmaniasis</a>, <a href="https://publications.waset.org/abstracts/search?q=Leishmania%20tropica" title=" Leishmania tropica"> Leishmania tropica</a>, <a href="https://publications.waset.org/abstracts/search?q=sandflies" title=" sandflies"> sandflies</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunisia" title=" Tunisia"> Tunisia</a> </p> <a href="https://publications.waset.org/abstracts/127947/infection-of-phlebotomus-sergenti-with-leishmania-tropica-in-a-classical-focus-of-leishmania-major-in-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127947.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">167</span> Physicochemical Characterizations of Marine and River Sediments in the North of France</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abriak%20Nor%20Edine">Abriak Nor Edine</a>, <a href="https://publications.waset.org/abstracts/search?q=Zentar%20Rachid"> Zentar Rachid</a>, <a href="https://publications.waset.org/abstracts/search?q=Achour%20Raouf"> Achour Raouf</a>, <a href="https://publications.waset.org/abstracts/search?q=Tran%20Ngoc%20Thanh"> Tran Ngoc Thanh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work is undertaken to develop a methodology to enhance the management of dredged marine and river sediments in the North of France.

From the obtained results, the potential of their use in road engineering is discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=marine%20sediments" title="marine sediments">marine sediments</a>, <a href="https://publications.waset.org/abstracts/search?q=river%20sediments" title=" river sediments"> river sediments</a>, <a href="https://publications.waset.org/abstracts/search?q=physico%20chemical%20characterizations" title=" physico chemical characterizations"> physico chemical characterizations</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20characterizations" title=" environmental characterizations"> environmental characterizations</a> </p> <a href="https://publications.waset.org/abstracts/18912/physicochemical-characterizations-of-marine-and-river-sediments-in-the-north-of-france" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18912.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">548</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">166</span> Optimization of Dual Band Antenna on Silicon Substrate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syrine%20lahmadi">Syrine lahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamel%20Bel%20Hadj%20Tahar"> Jamel Bel Hadj Tahar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a rectangular antenna with slots integrated on silicon substrate operating in 60GHz, is studied and optimized. The effect of different parameter of the antenna (width, length, the position of the microstrip-feed line...) and the parameter of the substrate (the thickness, the dielectric constant) on gain, frequency is presented. Also, the paper presents a solution to ameliorate the bandwidth. The maximum simulated radiation gain of this rectangular dual band antenna is 5, 38 dB around 60GHz. The simulation studied id developed based on advanced design system tools. It is found that the designed antenna is 19 % smaller than a rectangular antenna with the same dimensions. This antenna with dual band can function for many communication systems as automobile or radar. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dual%20band" title="dual band">dual band</a>, <a href="https://publications.waset.org/abstracts/search?q=enlargement%20of%20bandwidth" title=" enlargement of bandwidth"> enlargement of bandwidth</a>, <a href="https://publications.waset.org/abstracts/search?q=miniaturized%20antennas" title=" miniaturized antennas"> miniaturized antennas</a>, <a href="https://publications.waset.org/abstracts/search?q=printed%20antenna" title=" printed antenna"> printed antenna</a> </p> <a href="https://publications.waset.org/abstracts/30092/optimization-of-dual-band-antenna-on-silicon-substrate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30092.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">358</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">165</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. The main objective of this study is 2D modeling of hydrogen production in inductively coupled plasma in methane at low pressure. In the present model, we include the motions and the collisions of both neutral and charged particles by considering 19 species (i.e in total ; neutrals, radicals, ions, and electrons), and more than 120 reactions (electron impact with methane, neutral-neutral, neutral-ions and surface reactions). The results show that the rate conversion of methane reach 90% and the hydrogen production is about 30%. <p class="card-text"><strong>Keywords:</strong> <a
