Jean</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this investigation, the particle swarm optimization (PSO) algorithm is used to perform the inversion of the dispersion curves in the spectral analysis of surface waves (SASW) method. This inverse problem usually presents complicated solution spaces with many local minima that make difficult the convergence to the correct solution. PSO is a metaheuristic method that was originally designed to simulate social behavior but has demonstrated powerful capabilities to solve inverse problems with complex space solution and a high number of variables. The dispersion curve of the synthetic soils is constructed by the vertical flexibility coefficient method, which is especially convenient for soils where the stiffness does not increase gradually with depth. The reason is that these types of soil profiles are not normally dispersive since the dominant mode of Rayleigh waves is usually not coincident with the fundamental mode. Multiple synthetic soil profiles have been tested to show the characteristics of the convergence process and assess the accuracy of the final soil profile. In addition, the inversion procedure is applied to multiple real soils and the final profile compared with the available information. The combination of the vertical flexibility coefficient method to obtain the dispersion curve and the PSO algorithm to carry out the inversion process proves to be a robust procedure that is able to provide good solutions for complex soil profiles even with scarce prior information. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dispersion" title="dispersion">dispersion</a>, <a href="https://publications.waset.org/abstracts/search?q=inverse%20problem" title=" inverse problem"> inverse problem</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization" title=" particle swarm optimization"> particle swarm optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=SASW" title=" SASW"> SASW</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20profile" title=" soil profile"> soil profile</a> </p> <a href="https://publications.waset.org/abstracts/87227/inversion-of-the-spectral-analysis-of-surface-waves-dispersion-curves-through-the-particle-swarm-optimization-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87227.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">185</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">1167</span> Social Data Aggregator and Locator of Knowledge (STALK)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rashmi%20Raghunandan">Rashmi Raghunandan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjana%20Shankar"> Sanjana Shankar</a>, <a href="https://publications.waset.org/abstracts/search?q=Rakshitha%20K.%20Bhat"> Rakshitha K.

This project will greatly reduce the need for unnecessary manual analysis of large and diverse social media profiles by filtering out and combining the useful information from various social media profiles, eliminating irrelevant data. It differs from the existing social media aggregators in that it does not provide a consolidated view of various profiles. Instead, it provides consolidated INFORMATION derived from the subject’s posts and other activities. It also allows analysis over multiple profiles and analytics based on several profiles. We strive to provide a query system to provide a natural language answer to questions when a user does not wish to go through the entire profile. The information provided can be filtered according to the different use cases it is used for. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20network" title="social network">social network</a>, <a href="https://publications.waset.org/abstracts/search?q=analysis" title=" analysis"> analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Facebook" title=" Facebook"> Facebook</a>, <a href="https://publications.waset.org/abstracts/search?q=Linkedin" title=" Linkedin"> Linkedin</a>, <a href="https://publications.waset.org/abstracts/search?q=git" title=" git"> git</a>, <a href="https://publications.waset.org/abstracts/search?q=big%20data" title=" big data"> big data</a> </p> <a href="https://publications.waset.org/abstracts/37509/social-data-aggregator-and-locator-of-knowledge-stalk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37509.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">444</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">1166</span> Closed Form Solution for 4-D Potential Integrals for Arbitrary Coplanar Polygonal Surfaces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Damir%20Latypov">Damir Latypov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A closed-form solution for 4-D double surface integrals arising in boundary integrals equations of a potential theory is obtained for arbitrary coplanar polygonal surfaces. The solution method is based on the construction of exact differential forms followed by the application of Stokes' theorem for each surface integral. As a result, the 4-D double surface integral is reduced to a 2-D double line integral. By an appropriate change of variables, the integrand is transformed into a separable function of integration variables. The closed-form solutions to the corresponding 1-D integrals are readily available in the integration tables. Previously closed-form solutions were known only for the case of coincident triangle surfaces and coplanar rectangles. Solutions for these cases were obtained by surface-specific ad-hoc methods, while the present method is general. The method also works for non-polygonal surfaces. As an example, we compute in closed form the 4-D integral for the case of coincident surfaces in the shape of a circular disk. For an arbitrarily shaped surface, the proposed method provides an efficient quadrature rule. Extensions of the method for non-coplanar surfaces and other than 1/R integral kernels are also discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boundary%20integral%20equations" title="boundary integral equations">boundary integral equations</a>, <a href="https://publications.waset.org/abstracts/search?q=differential%20forms" title=" differential forms"> differential forms</a>, <a href="https://publications.waset.org/abstracts/search?q=integration" title=" integration"> integration</a>, <a href="https://publications.waset.org/abstracts/search?q=stokes%27%20theorem" title=" stokes' theorem"> stokes' theorem</a> </p> <a href="https://publications.waset.org/abstracts/130006/closed-form-solution-for-4-d-potential-integrals-for-arbitrary-coplanar-polygonal-surfaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130006.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">310</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">1165</span> A Design System for Complex Profiles of Machine Members Using a Synthetic Curve</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Sateesh">N.

We exploit the classical behavior of users and integrate a delimitation process of their research activities into several research sessions enriched with contextual and temporal information, which allows reflecting the current interests of these users in every period of time and infer data freshness. We argue that the annotation of resources gives more transparency on users' needs. It also strengthens social links among resources and users, and can so increase the scope of the user profile. Based on this idea, we integrate the social tagging practice in order to exploit the social users' behavior to enrich their profiles. These profiles are then integrated into a recommendation system in order to predict the interesting personalized items of users allowing to assist them in their researches and further enrich their profiles. In this recommendation, we provide users new research experiences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=user%20profiles" title="user profiles">user profiles</a>, <a href="https://publications.waset.org/abstracts/search?q=topical%20ontology" title=" topical ontology"> topical ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=contextual%20%20information" title=" contextual information"> contextual information</a>, <a href="https://publications.waset.org/abstracts/search?q=folksonomies" title=" folksonomies"> folksonomies</a>, <a href="https://publications.waset.org/abstracts/search?q=tags%27%20clusters" title=" tags' clusters"> tags' clusters</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20freshness" title=" data freshness"> data freshness</a>, <a href="https://publications.waset.org/abstracts/search?q=association%20rules" title=" association rules"> association rules</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20recommendation" title=" data recommendation"> data recommendation</a> </p> <a href="https://publications.waset.org/abstracts/56995/social-data-based-users-profiles-enrichment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56995.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">1163</span> Sensitivity Analysis Optimization of a Horizontal Axis Wind Turbine from Its Aerodynamic Profiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Molina">Kevin Molina</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Ortega"> Daniel Ortega</a>, <a href="https://publications.waset.org/abstracts/search?q=Manuel%20Martinez"> Manuel Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Andres%20Gonzalez-Estrada"> Andres Gonzalez-Estrada</a>, <a href="https://publications.waset.org/abstracts/search?q=William%20Pinto"> William Pinto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the increasing environmental impact, the wind energy is getting strong. This research studied the relationship between the power produced by a horizontal axis wind turbine (HAWT) and the aerodynamic profiles used for its construction. The analysis is studied using the Computational Fluid Dynamic (CFD), presenting the parallel between the energy generated by a turbine designed with selected profiles and another one optimized. For the study, a selection process was carried out from profile NACA 6 digits recommended by the National Renewable Energy Laboratory (NREL) for the construction of this type of turbines. The selection was taken into account different characteristics of the wind (speed and density) and the profiles (aerodynamic coefficients Cl and Cd to different Reynolds and incidence angles). From the selected profiles, was carried out a sensitivity analysis optimization process between its geometry and the aerodynamic forces that are induced on it. The 3D model of the turbines was realized using the Blade Element Momentum method (BEM) and both profiles. The flow fields on the turbines were simulated, obtaining the forces induced on the blade, the torques produced and an increase of 3% in power due to the optimized profiles. Therefore, the results show that the sensitivity analysis optimization process can assist to increment the wind turbine power. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blade%20element%20momentum" title="blade element momentum">blade element momentum</a>, <a href="https://publications.waset.org/abstracts/search?q=blade" title=" blade"> blade</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid%20structure%20interaction" title=" fluid structure interaction"> fluid structure interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=horizontal%20axis%20wind%20turbine" title=" horizontal axis wind turbine"> horizontal axis wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=profile%20design" title=" profile design"> profile design</a> </p> <a href="https://publications.waset.org/abstracts/85165/sensitivity-analysis-optimization-of-a-horizontal-axis-wind-turbine-from-its-aerodynamic-profiles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85165.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">259</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">1162</span> An Architectural Approach for the Dynamic Adaptation of Services-Based Software</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohhamed%20Yassine%20Baroudi">Mohhamed Yassine Baroudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelkrim%20Benammar"> Abdelkrim Benammar</a>, <a href="https://publications.waset.org/abstracts/search?q=Fethi%20Tarik%20Bendimerad"> Fethi Tarik Bendimerad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes software architecture for dynamical service adaptation.

The charts of the patients were reviewed to evaluate body mass index and lipid profiles, including total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides (TG), confounding factors, such as other general medical disorders (hypertension, diabetes mellitus, and dyslipidemia), except smoking status (insufficient data). Demographic and clinical characteristics, such as age, sex, comorbidities, family history of mood disorders, psychotic features, and prescription patterns were also assessed. Results: Compared to the mild to the moderate depressive group, patients with severe depression had significantly lower rate of male and comorbidity. The patients with severe depression had a significantly lower TG than patients in the mild to moderate depressive group. After adjustment for the sex and comorbidity, there were no significant differences between the two groups in terms of the obesity and lipid profiles, including TG. Conclusion: These results did not show a significant difference in the association between obesity, lipid profiles and the depression severity. The role of obesity and lipid profiles in the pathophysiology of depression remains to be clarified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=depression" title="depression">depression</a>, <a href="https://publications.waset.org/abstracts/search?q=HAM-D" title=" HAM-D"> HAM-D</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20profiles" title=" lipid profiles"> lipid profiles</a>, <a href="https://publications.waset.org/abstracts/search?q=obesity" title=" obesity"> obesity</a> </p> <a href="https://publications.waset.org/abstracts/62955/the-association-among-obesity-lipid-profiles-and-depression-severity-in-patients-with-depressive-disorder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62955.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">288</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">1160</span> Biochemical Identification and Study of Antibiotic Resistance in Isolated Bacteria from WWTP TIMGAD</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdessemed%20Zineb">Abdessemed Zineb</a>, <a href="https://publications.waset.org/abstracts/search?q=Atia%20Yahia"> Atia Yahia</a>, <a href="https://publications.waset.org/abstracts/search?q=Yeza%20Salima"> Yeza Salima </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water is self-purified by activated sludge process which makes its uniqueness.

One group had high level on the five dimensions of job characteristic (D group), whereas another group had low level on the dimensions (R group).

A large transmitter loop for energising the ground and a small receiver loop or magnetometer for recording the transient voltage or magnetic field in the air or on the surface of the earth, with the receiver at the center of the loop or at any random point inside or outside the source loop, make up a large loop TEM system. In general, one can acquire data using one of the configurations with a large loop source, namely, with the receiver at the center point of the loop (central loop method), at an arbitrary in-loop point (in-loop method), coincident with the transmitter loop (coincidence-loop method), and at an arbitrary offset loop point (offset-loop method), respectively. Because of the mathematical simplicity associated with the expressions of EM fields, as compared to the in-loop and offset-loop systems, the central loop system (for ground surveys) and coincident loop system (for ground as well as airborne surveys) have been developed and used extensively for the exploration of mineral and geothermal resources, for mapping contaminated groundwater caused by hazardous waste and thickness of permafrost layer. Because a proper analytical expression for the TEM response over the layered earth model for the large loop TEM system does not exist, the forward problem used in this inversion scheme is first formulated in the frequency domain and then it is transformed in the time domain using Fourier cosine or sine transforms. Using the EMLCLLER algorithm, the forward computation is initially carried out in the frequency domain. As a result, the EMLCLLER modified the forward calculation scheme in NLSTCI to compute frequency domain answers before converting them to the time domain using Fourier Cosine and/or Sine transforms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=time%20domain%20electromagnetic%20%28TDEM%29" title="time domain electromagnetic (TDEM)">time domain electromagnetic (TDEM)</a>, <a href="https://publications.waset.org/abstracts/search?q=TEM%20system" title=" TEM system"> TEM system</a>, <a href="https://publications.waset.org/abstracts/search?q=geoelectrical%20sounding%20structure" title=" geoelectrical sounding structure"> geoelectrical sounding structure</a>, <a href="https://publications.waset.org/abstracts/search?q=Fourier%20cosine" title=" Fourier cosine"> Fourier cosine</a> </p> <a href="https://publications.waset.org/abstracts/161195/conductivity-depth-inversion-of-large-loop-transient-electromagnetic-sounding-data-over-layered-earth-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161195.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">92</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">1155</span> Reconnaissance Geophysical Study on the Southeastern Part of Al-Qashah Aera, Kingdom of Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Al-Bakri">Ali Al-Bakri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Sazid"> Mohammed Sazid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The investigated study area locates about 72 km from Jeddah city, Makkah district, Kingdom of Saudi Arabia. The study mainly aimed to define only in detail the most significant zones of possible mineralization and outline their subsurface parameters (location and strike) in the southeast part of Jabal Al-Qashah. Several geophysical methods have been conducted to carry out the goal. Among these methods are the ground magnetic method, self-potential (SP) method, and induced polarization (IP) method. Integrating these methods aims to help in delineating the possible mineralization in the study area. The magnetic survey was conducted along 17 profiles where these profiles were chosen to be perpendicular to the strike of the quartz shear zone. Self-potential was applied along with five profiles covering the study area. At the same time, induced polarization was used along with one profile located at the western side of the study area corresponding to some magnetic and SP profiles. The most interesting zones of mineralization were successfully determined by comparing the results of residual magnetic profile (3), SP profile (1), and IP profile, where geological structures control some mineralization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geophysical%20methods" title="geophysical methods">geophysical methods</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20method" title=" magnetic method"> magnetic method</a>, <a href="https://publications.waset.org/abstracts/search?q=self-potential" title=" self-potential"> self-potential</a>, <a href="https://publications.waset.org/abstracts/search?q=induced%20polarization" title=" induced polarization"> induced polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=Jabal%20Al-Qashah" title=" Jabal Al-Qashah"> Jabal Al-Qashah</a> </p> <a href="https://publications.waset.org/abstracts/151546/reconnaissance-geophysical-study-on-the-southeastern-part-of-al-qashah-aera-kingdom-of-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151546.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">131</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">1154</span> Determination of Weld Seam Thickness in Welded Connection Subjected to Local Buckling Effects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tugrul%20Tulunay">Tugrul Tulunay</a>, <a href="https://publications.waset.org/abstracts/search?q=Iyas%20Devran%20Celik"> Iyas Devran Celik</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When the materials used in structural steel industry are evaluated, box beam profiles are considerably preferred. As a result of the cross-sectional properties that these profiles possess, the connection of these profiles to each other and to profiles having different types of cross sections is becoming viable by means of additional measures. An important point to note in such combinations is continuous transfer of internal forces from element to element. At the beginning to ensure this continuity, header plate is needed to use. The connection of the plates to the elements works mainly through welds. In this study, it is aimed to determine the ideal welding thickness in box beam under bending effect and the joints exposed to local buckles that will form in the column. The connection with box column and box beam designed in this context was made by means of corner and circular filler welds. Corner welds of different thickness and analysis by types with different lengths depending on plate dimensions in numerical models were made with the help of ANSYS Workbench program and examined behaviours. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=welding%20thickness" title="welding thickness">welding thickness</a>, <a href="https://publications.waset.org/abstracts/search?q=box%20beam-column%20joints" title=" box beam-column joints"> box beam-column joints</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20steel%20structures" title=" design of steel structures"> design of steel structures</a>, <a href="https://publications.waset.org/abstracts/search?q=calculation%20and%20construction%20principles%202016" title=" calculation and construction principles 2016"> calculation and construction principles 2016</a>, <a href="https://publications.waset.org/abstracts/search?q=welded%20joints%20under%20local%20buckling" title=" welded joints under local buckling"> welded joints under local buckling</a> </p> <a href="https://publications.waset.org/abstracts/82407/determination-of-weld-seam-thickness-in-welded-connection-subjected-to-local-buckling-effects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82407.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">1153</span> Driver Behavior Analysis and Inter-Vehicular Collision Simulation Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lu%20Zhao">Lu Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadir%20Farhi"> Nadir Farhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zoi%20Christoforou"> Zoi Christoforou</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Haddadou"> Nadia Haddadou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The safety test of deploying intelligent connected vehicles (ICVs) on the road network is a critical challenge. Road traffic network simulation can be used to test the functionality of ICVs, which is not only time-saving and less energy-consuming but also can create scenarios with car collisions. However, the relationship between different human driver behaviors and the car-collision occurrences has been not understood clearly; meanwhile, the procedure of car-collisions generation in the traffic numerical simulators is not fully integrated. In this paper, we propose an approach to identify specific driver profiles from real driven data; then, we replicate them in numerical traffic simulations with the purpose of generating inter-vehicular collisions. We proposed three profiles: (i) 'aggressive': short time-headway, (ii) 'inattentive': long reaction time, and (iii) 'normal' with intermediate values of reaction time and time-headway. These three driver profiles are extracted from the NGSIM dataset and simulated using the intelligent driver model (IDM), with an extension of reaction time. At last, the generation of inter-vehicular collisions is performed by varying the percentages of different profiles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vehicular%20collisions" title="vehicular collisions">vehicular collisions</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20driving%20behavior" title=" human driving behavior"> human driving behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20modeling" title=" traffic modeling"> traffic modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=car-following%20models" title=" car-following models"> car-following models</a>, <a href="https://publications.waset.org/abstracts/search?q=microscopic%20traffic%20simulation" title=" microscopic traffic simulation"> microscopic traffic simulation</a> </p> <a href="https://publications.waset.org/abstracts/139723/driver-behavior-analysis-and-inter-vehicular-collision-simulation-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139723.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">1152</span> Velocity Distribution in Density Currents Flowing over Rough Beds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Nasrollahpour">Reza Nasrollahpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Hidayat%20Bin%20Jamal"> Mohamad Hidayat Bin Jamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Zulhilmi%20Bin%20Ismail"> Zulhilmi Bin Ismail</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Density currents are generated when the fluid of one density is released into another fluid with a different density. These currents occur in a variety of natural and man-made environments, and this emphasises the importance of studying them. In most practical cases, the density currents flow over the surfaces which are not plane; however, there have been limited investigations in this regard. This study uses laboratory experiments to analyse the influence of bottom roughness on the velocity distribution within these dense underflows. The currents are analysed over a plane surface and three different configurations of beam-roughened beds. The velocity profiles are collected using Acoustic Doppler Velocimetry technique, and the distribution of velocity within these currents is formulated for the tested beds. The results indicate that the empirical power and Gaussian relations can describe the velocity distribution in the inner and outer regions of the profiles, respectively. Moreover, it is found that the bottom roughness is the primary controlling parameter in the inner region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=density%20currents" title="density currents">density currents</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity%20profiles" title=" velocity profiles"> velocity profiles</a>, <a href="https://publications.waset.org/abstracts/search?q=Acoustic%20Doppler%20Velocimeter" title=" Acoustic Doppler Velocimeter"> Acoustic Doppler Velocimeter</a>, <a href="https://publications.waset.org/abstracts/search?q=bed%20roughness" title=" bed roughness"> bed roughness</a> </p> <a href="https://publications.waset.org/abstracts/96631/velocity-distribution-in-density-currents-flowing-over-rough-beds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96631.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">185</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">1151</span> Molecular Survey and Genetic Diversity of Bartonella henselae Strains Infecting Stray Cats from Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naouelle%20Azzag">Naouelle Azzag</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Haddad"> Nadia Haddad</a>, <a href="https://publications.waset.org/abstracts/search?q=Benoit%20Durand"> Benoit Durand</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Petit"> Elisabeth Petit</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ammouche"> Ali Ammouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20Chomel"> Bruno Chomel</a>, <a href="https://publications.waset.org/abstracts/search?q=Henri%20J.%20Boulouis"> Henri J.

Whole blood of 227 stray cats from Algiers was tested for the presence of Bartonella species by culture and for the evaluation of the genetic diversity of B. henselae strains by multi-locus variable number of tandem repeats assay (MLVA). Bacteremia prevalence was 17% and only B. henselae was identified. Type I was the predominant type (64%). MLVA typing of 259 strains from 30 bacteremic cats revealed 52 different profiles. 51 of these profiles were specific to Algerian cats/identified for the first time. 20/30 cats (67%) harbored 2 to 7 MLVA profiles simultaneously. The similarity of MLVA profiles obtained from the same cat, neighbor-joining clustering and structure-neighbor clustering showed that such a diversity likely results from two different mechanisms occurring either independently or simultaneously independent infections and genetic drift from a primary strain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bartonella" title="Bartonella">Bartonella</a>, <a href="https://publications.waset.org/abstracts/search?q=cat" title=" cat"> cat</a>, <a href="https://publications.waset.org/abstracts/search?q=MLVA" title=" MLVA"> MLVA</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic" title=" genetic"> genetic</a> </p> <a href="https://publications.waset.org/abstracts/108213/molecular-survey-and-genetic-diversity-of-bartonella-henselae-strains-infecting-stray-cats-from-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108213.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">149</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1150</span> Hematological Profiles of Visceral Leishmaniasis Patients before and after Treatment of Anti-Leishmanial Drugs at University of Gondar Leishmania Research and Treatment Center Northwest, Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fitsumbrhan%20Tajebe">Fitsumbrhan Tajebe</a>, <a href="https://publications.waset.org/abstracts/search?q=Fadil%20Murad"> Fadil Murad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mitikie%20%20Tigabie"> Mitikie Tigabie</a>, <a href="https://publications.waset.org/abstracts/search?q=Mareye%20Abebaw"> Mareye Abebaw</a>, <a href="https://publications.waset.org/abstracts/search?q=Tadele%20Alemu"> Tadele Alemu</a>, <a href="https://publications.waset.org/abstracts/search?q=Sefanit%20Abate"> Sefanit Abate</a>, <a href="https://publications.waset.org/abstracts/search?q=Rezika%20Mohammedw"> Rezika Mohammedw</a>, <a href="https://publications.waset.org/abstracts/search?q=Arega%20Yeshanew"> Arega Yeshanew</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20Shiferaw"> Elias Shiferaw</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Visceral leshimaniasis is a parasitic disease characterized by a systemic infection of phagocytic cells. Hematological parameters of these patients may be affected by the progress of the disease or treatment. Thus, the current study aimed to assess the hematological profiles of visceral leishmaniasis patients before and after treatment. Method: An institutional based retrospective cohort study was conducted among visceral leishmaniasis patients at University of Gondar Comprehensive Specialized Referral Hospital Leishmaniasis Research and Treatment Center from 2013 to 2018. Hematological profiles before initiation and after completion of treatment were extracted from registration book. Descriptive statics was presented using frequency and percentage. Paired t-test and Wilcoxon Signed rank test were used for comparing mean difference for normally and non- normally distributed data, respectively. Spearman and Pearson correlation analysis was used to describe the correlation of hematological parameters with different variables. P value < 0.05 was considered as statistically significant. Result: Except absolute nerutrophil count, post treatment hematological parameters show a significant increment compared to pretreatment one. The prevalence of anemia, leucopenia and thrombocytopenia was 85.5%, 83.4% and 75.8% prior to treatment and it was 58.3%, 38.2% and 19.2% after treatment, respectively. Moreover, parasite load of the disease showed statistically significant negative correlation with hematological profiles mainly with white blood cell and red blood cell. Conclusion: Majority of hematological profiles of patients with active VL have been restored after treatment, which might be associated with treatment effect on parasite proliferation and concentration of parasite in visceral organ, which directly affect hematological profiles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=visceral%20leshimaniasis" title="visceral leshimaniasis">visceral leshimaniasis</a>, <a href="https://publications.waset.org/abstracts/search?q=hematological%20profile" title=" hematological profile"> hematological profile</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-leshimanial%20drug" title=" anti-leshimanial drug"> anti-leshimanial drug</a>, <a href="https://publications.waset.org/abstracts/search?q=Gondar" title=" Gondar"> Gondar</a> </p> <a href="https://publications.waset.org/abstracts/122906/hematological-profiles-of-visceral-leishmaniasis-patients-before-and-after-treatment-of-anti-leishmanial-drugs-at-university-of-gondar-leishmania-research-and-treatment-center-northwest-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122906.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">1149</span> Training the Competences for the 'Expert Teacher': A Framework of Skills for Teachers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sofia%20Cramerotti">Sofia Cramerotti</a>, <a href="https://publications.waset.org/abstracts/search?q=Angela%20Cattoni"> Angela Cattoni</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Biancato"> Laura Biancato</a>, <a href="https://publications.waset.org/abstracts/search?q=Dario%20Ianes"> Dario Ianes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The recognition of specific standards for new professionals, within the teaching profile, is a necessary process in order to foster an innovative school vision in accordance with the change that school is experiencing. In line with the reform of the national education and training system and with the National Training Plan for teachers, our Research and Development department developed a training project based on a framework (Syllabus) of skills that each 'Expert Teacher' should master in order to fulfill what the different specific profiles request. The syllabus is a fundamental tool for a training process consistent with the teaching profiles, both to guide the to-become teachers entering in service and to provide the in-service teachers with a system of evaluation and improvement of their skills. According to the national and international literature about professional standards for teachers, we aggregated the skills of the syllabus in three macro areas: (1) Area of professional skills related to the teacher profile and their continuous training; (2) area of teaching skills related to the school innovation; (3) area of organizing skills related to school participation for its improvement. The syllabus is a framework that identifies and describes the skills of the expert teacher in all of their roles. However, the various skills take on different importance in the different profiles involved in the school; some of those skills are determining a role, others could be secondary. Therefore, the characterization of the different profiles is represented by suitably weighted skills sets. In this way, the same skill could differently characterize each profile. In the future, we hope that the skills development and training for the teacher could evolve in a skills development and training for the whole school staff ('Expert Team'). In this perspective, the school will, therefore, benefit from a solid team, in which the skills of the various profiles are all properly developed and well represented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=framework" title="framework">framework</a>, <a href="https://publications.waset.org/abstracts/search?q=skills" title=" skills"> skills</a>, <a href="https://publications.waset.org/abstracts/search?q=teachers" title=" teachers"> teachers</a>, <a href="https://publications.waset.org/abstracts/search?q=training" title=" training"> training</a> </p> <a href="https://publications.waset.org/abstracts/90160/training-the-competences-for-the-expert-teacher-a-framework-of-skills-for-teachers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90160.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">180</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">1148</span> An Experimental (Wind Tunnel) and Numerical (CFD) Study on the Flow over Hills</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tanit%20Daniel%20Jodar%20Vecina">Tanit Daniel Jodar Vecina</a>, <a href="https://publications.waset.org/abstracts/search?q=Adriane%20Prisco%20Petry"> Adriane Prisco Petry</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The shape of the wind velocity profile changes according to local features of terrain shape and roughness, which are parameters responsible for defining the Atmospheric Boundary Layer (ABL) profile. Air flow characteristics over and around landforms, such as hills, are of considerable importance for applications related to Wind Farm and Turbine Engineering. The air flow is accelerated on top of hills, which can represent a decisive factor for Wind Turbine placement choices. The present work focuses on the study of ABL behavior as a function of slope and surface roughness of hill-shaped landforms, using the Computational Fluid Dynamics (CFD) to build wind velocity and turbulent intensity profiles. Reynolds-Averaged Navier-Stokes (RANS) equations are closed using the SST k-ω turbulence model; numerical results are compared to experimental data measured in wind tunnel over scale models of the hills under consideration. Eight hill models with slopes varying from 25° to 68° were tested for two types of terrain categories in 2D and 3D, and two analytical codes are used to represent the inlet velocity profiles. Numerical results for the velocity profiles show differences under 4% when compared to their respective experimental data. Turbulent intensity profiles show maximum differences around 7% when compared to experimental data; this can be explained by not being possible to insert inlet turbulent intensity profiles in the simulations. Alternatively, constant values based on the averages of the turbulent intensity at the wind tunnel inlet were used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atmospheric%20Boundary%20Layer" title="Atmospheric Boundary Layer">Atmospheric Boundary Layer</a>, <a href="https://publications.waset.org/abstracts/search?q=Computational%20Fluid%20Dynamic%20%28CFD%29" title=" Computational Fluid Dynamic (CFD)"> Computational Fluid Dynamic (CFD)</a>, <a href="https://publications.waset.org/abstracts/search?q=Numerical%20Modeling" title=" Numerical Modeling"> Numerical Modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=Wind%20Tunnel" title=" Wind Tunnel"> Wind Tunnel</a> </p> <a href="https://publications.waset.org/abstracts/66766/an-experimental-wind-tunnel-and-numerical-cfd-study-on-the-flow-over-hills" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66766.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">1147</span> Implication of Soil and Seismic Ground Motion Variability on Dynamic Pile Group Impedance for Bridges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Tariq%20Chaudhary">Muhammad Tariq Chaudhary</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bridges constitute a vital link in a transportation system and their functionality after an earthquake is critical in reducing disruption to social and economic activities of the society. Bridges supported on pile foundations are commonly used in many earthquake-prone regions. In order to properly design or investigate the performance of such structures, it is imperative that the effect of soil-foundation-structure interaction be properly taken into account. This study focused on the influence of soil and seismic ground motion variability on the dynamic impedance of pile-group foundations typically used for medium-span (about 30 m) urban viaduct bridges. Soil profiles corresponding to various AASHTO soil classes were selected from actual data of such bridges and / or from the literature. The selected soil profiles were subjected to 1-D wave propagation analysis to determine effective values of soil shear modulus and damping ratio for a suite of properly selected actual seismic ground motions varying in PGA from 0.01g to 0.64g, and having variable velocity and frequency content. The effective values of the soil parameters were then employed to determine the dynamic impedance of pile groups in horizontal, vertical and rocking modes in various soil profiles. Pile diameter was kept constant for bridges in various soil profiles while pile length and number of piles were changed based on AASHTO design requirements for various soil profiles and earthquake ground motions. Conclusions were drawn regarding variability in effective soil shear modulus, soil damping, shear wave velocity and pile group impedance for various soil profiles and ground motions and its implications for design and evaluation of pile-supported bridges. It was found that even though the effective soil parameters underwent drastic variation with increasing PGA, the pile group impedance was not affected much in properly designed pile foundations due to the corresponding increase in pile length or increase in a number of piles or both when subjected to increasing PGA or founded in weaker soil profiles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bridge" title="bridge">bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=pile%20foundation" title=" pile foundation"> pile foundation</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20foundation%20impedance" title=" dynamic foundation impedance"> dynamic foundation impedance</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20profile" title=" soil profile"> soil profile</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20wave%20velocity" title=" shear wave velocity"> shear wave velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20ground%20motion" title=" seismic ground motion"> seismic ground motion</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20wave%20propagation" title=" seismic wave propagation"> seismic wave propagation</a> </p> <a href="https://publications.waset.org/abstracts/45773/implication-of-soil-and-seismic-ground-motion-variability-on-dynamic-pile-group-impedance-for-bridges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45773.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">324</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">1146</span> Application of the Seismic Reflection Survey to an Active Fault Imaging</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nomin-Erdene%20Erdenetsogt">Nomin-Erdene Erdenetsogt</a>, <a href="https://publications.waset.org/abstracts/search?q=Tseedulam%20Khuut"> Tseedulam Khuut</a>, <a href="https://publications.waset.org/abstracts/search?q=Batsaikhan%20Tserenpil"> Batsaikhan Tserenpil</a>, <a href="https://publications.waset.org/abstracts/search?q=Bayarsaikhan%20Enkhee"> Bayarsaikhan Enkhee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As the framework of 60 years of development of Astronomical and Geophysical science in modern Mongolia, various geophysical methods (electrical tomography, ground-penetrating radar, and high-resolution reflection seismic profiles) were used to image an active fault in-depth range between few decimeters to few tens meters.

The main emphasis is placed on a comparison of experimental and computational investigations into the effects of the rotation speed of the inner pipe on the axial velocity profiles. The computational investigations were carried out by employing CFD software, and Gambit and Fluent. Three turbulence models were used: standard, RNG with enhanced wall treatment, and SST model. The profiles of the axial velocity had investigated at different rotation speeds of the inner pipe with three different volumetric flow rates. The comparison results showed that the calculations satisfactorily predict the qualitative features of the axial and swirl velocity profiles and the RNG model performs the best results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics%20%28CFD%29" title="computational fluid dynamics (CFD)">computational fluid dynamics (CFD)</a>, <a href="https://publications.waset.org/abstracts/search?q=SST%20k%E2%88%92%CF%89%20shear-stress%20transport%20%28k%E2%88%92%CF%89%20mode%20variant%29" title=" SST k−ω shear-stress transport (k−ω mode variant)"> SST k−ω shear-stress transport (k−ω mode variant)</a>, <a href="https://publications.waset.org/abstracts/search?q=RNG%20k%E2%80%93%CE%B5%20renormalisation%20group%20%28k%E2%88%92%CE%B5%20mode%20variant%29" title=" RNG k–ε renormalisation group (k−ε mode variant)"> RNG k–ε renormalisation group (k−ε mode variant)</a>, <a href="https://publications.waset.org/abstracts/search?q=y%2B%20dimensionless%20distance%20from%20wall" title=" y+ dimensionless distance from wall"> y+ dimensionless distance from wall</a> </p> <a href="https://publications.waset.org/abstracts/11778/a-comparison-of-computational-and-experimental-data-to-investigate-the-influence-of-the-tangential-velocity-of-inner-rotating-wall-on-axial-velocity-profile-of-flow-through-vertical-annular-pipe-with-rotating-inner-surface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11778.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">376</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">1144</span> Methodology to Achieve Non-Cooperative Target Identification Using High Resolution Range Profiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olga%20Hern%C3%A1n-Vega">Olga Hernán-Vega</a>, <a href="https://publications.waset.org/abstracts/search?q=Patricia%20L%C3%B3pez-Rodr%C3%ADguez"> Patricia López-Rodríguez</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Escot-Bocanegra"> David Escot-Bocanegra</a>, <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20Fern%C3%A1ndez-Recio"> Raúl Fernández-Recio</a>, <a href="https://publications.waset.org/abstracts/search?q=Ignacio%20Bravo"> Ignacio Bravo </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Non-Cooperative Target Identification has become a key research domain in the Defense industry since it provides the ability to recognize targets at long distance and under any weather condition. High Resolution Range Profiles, one-dimensional radar images where the reflectivity of a target is projected onto the radar line of sight, are widely used for identification of flying targets. According to that, to face this problem, an approach to Non-Cooperative Target Identification based on the exploitation of Singular Value Decomposition to a matrix of range profiles is presented. Target Identification based on one-dimensional radar images compares a collection of profiles of a given target, namely test set, with the profiles included in a pre-loaded database, namely training set. The classification is improved by using Singular Value Decomposition since it allows to model each aircraft as a subspace and to accomplish recognition in a transformed domain where the main features are easier to extract hence, reducing unwanted information such as noise. Singular Value Decomposition permits to define a signal subspace which contain the highest percentage of the energy, and a noise subspace which will be discarded. This way, only the valuable information of each target is used in the recognition process. The identification algorithm is based on finding the target that minimizes the angle between subspaces and takes place in a transformed domain. Two metrics, F1 and F2, based on Singular Value Decomposition are accomplished in the identification process. In the case of F2, the angle is weighted, since the top vectors set the importance in the contribution to the formation of a target signal, on the contrary F1 simply shows the evolution of the unweighted angle. In order to have a wide database or radar signatures and evaluate the performance, range profiles are obtained through numerical simulation of seven civil aircraft at defined trajectories taken from an actual measurement. Taking into account the nature of the datasets, the main drawback of using simulated profiles instead of actual measured profiles is that the former implies an ideal identification scenario, since measured profiles suffer from noise, clutter and other unwanted information and simulated profiles don't. In this case, the test and training samples have similar nature and usually a similar high signal-to-noise ratio, so as to assess the feasibility of the approach, the addition of noise has been considered before the creation of the test set. The identification results applying the unweighted and weighted metrics are analysed for demonstrating which algorithm provides the best robustness against noise in an actual possible scenario. So as to confirm the validity of the methodology, identification experiments of profiles coming from electromagnetic simulations are conducted, revealing promising results. Considering the dissimilarities between the test and training sets when noise is added, the recognition performance has been improved when weighting is applied. Future experiments with larger sets are expected to be conducted with the aim of finally using actual profiles as test sets in a real hostile situation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HRRP" title="HRRP">HRRP</a>, <a href="https://publications.waset.org/abstracts/search?q=NCTI" title=" NCTI"> NCTI</a>, <a href="https://publications.waset.org/abstracts/search?q=simulated%2Fsynthetic%20database" title=" simulated/synthetic database"> simulated/synthetic database</a>, <a href="https://publications.waset.org/abstracts/search?q=SVD" title=" SVD"> SVD</a> </p> <a href="https://publications.waset.org/abstracts/25021/methodology-to-achieve-non-cooperative-target-identification-using-high-resolution-range-profiles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25021.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">354</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">1143</span> Experimental Studies of Sigma Thin-Walled Beams Strengthen by CFRP Tapes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katarzyna%20Rzeszut">Katarzyna Rzeszut</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilona%20Szewczak"> Ilona Szewczak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The review of selected methods of strengthening of steel structures with carbon fiber reinforced polymer (CFRP) tapes and the analysis of influence of composite materials on the steel thin-walled elements are performed in this paper. The study is also focused to the problem of applying fast and effective strengthening methods of the steel structures made of thin-walled profiles. It is worth noting that the issue of strengthening the thin-walled structures is a very complex, due to inability to perform welded joints in this type of elements and the limited ability to applying mechanical fasteners. Moreover, structures made of thin-walled cross-section demonstrate a high sensitivity to imperfections and tendency to interactive buckling, which may substantially contribute to the reduction of critical load capacity. Due to the lack of commonly used and recognized modern methods of strengthening of thin-walled steel structures, authors performed the experimental studies of thin-walled sigma profiles strengthened with CFRP tapes. The paper presents the experimental stand and the preliminary results of laboratory test concerning the analysis of the effectiveness of the strengthening steel beams made of thin-walled sigma profiles with CFRP tapes. The study includes six beams made of the cold-rolled sigma profiles with height of 140 mm, wall thickness of 2.5 mm, and a length of 3 m, subjected to the uniformly distributed load. Four beams have been strengthened with carbon fiber tape Sika CarboDur S, while the other two were tested without strengthening to obtain reference results. Based on the obtained results, the evaluation of the accuracy of applied composite materials for strengthening of thin-walled structures was performed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFRP%20tapes" title="CFRP tapes">CFRP tapes</a>, <a href="https://publications.waset.org/abstracts/search?q=sigma%20profiles" title=" sigma profiles"> sigma profiles</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20thin-walled%20structures" title=" steel thin-walled structures"> steel thin-walled structures</a>, <a href="https://publications.waset.org/abstracts/search?q=strengthening" title=" strengthening"> strengthening</a> </p> <a href="https://publications.waset.org/abstracts/67413/experimental-studies-of-sigma-thin-walled-beams-strengthen-by-cfrp-tapes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67413.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">302</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">1142</span> Simulation of the Flow in Bilayer Coextrusion Dies with Gradually Changing Calibrator Profiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahesh%20Gupta">Mahesh Gupta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main goal in the design of a die for extrusion of a complex profile is to obtain a uniform velocity at the die exit. If the velocity at the exit of an extrusion die is not uniform, the shape of the extrudate profile can change significantly after the polymer exits the die. To rectify the extrudate distortion caused by non-uniform exit velocity, calibrators and sizers are often installed along the extrudate cooling system. Furthermore, the profile shape in calibrators and sizers is sometimes gradually changed to intentionally deform the extrudate to the required final product shape. This is exploited to simplify extrusion die design, because a relatively simple profile at the die exit can be modified to obtain a more complex profile by deforming it in calibrators or sizers. The gradual change in the shape of calibrator or sizer profiles can also be used to extrude slightly different profiles from the same die. In the present work, a combined flow, thermal and structural analysis is used to accurately predict distortion of extrudate profile after the polymer leaves a die. Simulations of the flow and extrudate deformation in two different bilayer coextrusion dies with gradually changing profile shape in successive calibrators and sizers will be presented. The effect of non-uniform exit velocity, cooling shrinkage and shape of sizer profiles on extrudate deformation is included in the simulation. The predicted extrudate shape and layer structure is found to match accurately with those in a coextruded product. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coextrusion" title="coextrusion">coextrusion</a>, <a href="https://publications.waset.org/abstracts/search?q=extrusion%20die%20design" title=" extrusion die design"> extrusion die design</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=polymers" title=" polymers"> polymers</a> </p> <a href="https://publications.waset.org/abstracts/185818/simulation-of-the-flow-in-bilayer-coextrusion-dies-with-gradually-changing-calibrator-profiles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185818.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">44</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">1141</span> The Potential of 48V HEV in Real Driving</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mark%20Schudeleit">Mark Schudeleit</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Sieg"> Christian Sieg</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferit%20K%C3%BC%C3%A7%C3%BCkay"> Ferit Küçükay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes how to dimension the electric components of a 48V hybrid system considering real customer use. Furthermore, it provides information about savings in energy and CO2 emissions by a customer-tailored 48V hybrid. Based on measured customer profiles, the electric units such as the electric motor and the energy storage are dimensioned. Furthermore, the CO2 reduction potential in real customer use is determined compared to conventional vehicles. Finally, investigations are carried out to specify the topology design and preliminary considerations in order to hybridize a conventional vehicle with a 48V hybrid system. The emission model results from an empiric approach also taking into account the effects of engine dynamics on emissions. We analyzed transient engine emissions during representative customer driving profiles and created emission meta models. The investigation showed a significant difference in emissions when simulating realistic customer driving profiles using the created verified meta models compared to static approaches which are commonly used for vehicle simulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=customer%20use" title="customer use">customer use</a>, <a href="https://publications.waset.org/abstracts/search?q=dimensioning" title=" dimensioning"> dimensioning</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20electric%20vehicles" title=" hybrid electric vehicles"> hybrid electric vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20simulation" title=" vehicle simulation"> vehicle simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=48V%20hybrid%20system" title=" 48V hybrid system"> 48V hybrid system</a> </p> <a href="https://publications.waset.org/abstracts/37159/the-potential-of-48v-hev-in-real-driving" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37159.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">507</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">1140</span> Interaction between NiCl2 and Selenium on Energy Profiles in Wistar albino Preimplanted Rats </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20Adjroud">O. Adjroud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study was conducted to investigate the interaction between selenium (Se) and chloride nickel (NiCl2) on energy profiles in Wistar albino preimplanted rats. NiCl2 was given on day 3 of pregnancy either in distilled drinking water at a dose of 20 mg/L/day for 16 consecutive days or as a single subcutaneous (s.c.) dose of 25, 50, or 100 mg/kg. Se was given as a s.c. injection (0.3 mg/kg) together with the higher dose (100 mg/kg) of NiCl2. Changes in energy profiles were evaluated in treated and control groups on days 5 and 20 of gestation. NiCl2 s.c. induced a significant increase in plasma glucose on day 20 of pregnancy. NiCl2 s.c. induced on day 5 and 20 of gestation a significant decrease in plasma triglycerides, with the higher dose. This decrease was maintained at day 20 of gestation with doses of 50 mg /kg. In addition, NiCl2 s.c. caused on day 5 of gestation a significant decrease in plasma total cholesterol with the low and medium doses. The pretreatment with Se reversed the effects of NiCl2 on plasma glucose, total cholesterol and triglycerides levels. NiCl2 administered in the drinking water augmented significantly the plasma triglycerides and total cholesterol levels and slighty the plasma glucose on day 20 of gestation, while on day 5 of gestation NiCl2 s.c. Induced a significant decrease in cholesterol. Three doses of NiCl2 (sc) induced severe alterations in liver and architecture which are markedly improved by Selenium. These results suggested that selenium has protective effects on energy profiles against the toxicity induced by NiCl2 administered subcutaneously in preimplanted rats. <p
