Every production/manufacturing unit mainly focuses on these areas in relation to the process, as well as the product developed. The electrical discharge machining (EDM) process, even now it is an experience process, wherein the selected parameters are still often far from the maximum, and at the same time selecting optimization parameters is costly and time consuming. Material Removal Rate (MRR) during the process has been considered as a productivity estimate with the aim to maximize it, with an intention of minimizing surface roughness taken as most important output parameter. These two opposites in nature requirements have been simultaneously satisfied by selecting an optimal process environment (optimal parameter setting). Objective function is obtained by Regression Analysis and Analysis of Variance. Then objective function is optimized using Genetic Algorithm technique. The model is shown to be effective; MRR and Surface Roughness improved using optimized machining parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MMR" title="MMR">MMR</a>, <a href="https://publications.waset.org/abstracts/search?q=TWR" title=" TWR"> TWR</a>, <a href="https://publications.waset.org/abstracts/search?q=OC" title=" OC"> OC</a>, <a href="https://publications.waset.org/abstracts/search?q=DOE" title=" DOE"> DOE</a>, <a href="https://publications.waset.org/abstracts/search?q=ANOVA" title=" ANOVA"> ANOVA</a>, <a href="https://publications.waset.org/abstracts/search?q=minitab" title=" minitab"> minitab</a> </p> <a href="https://publications.waset.org/abstracts/47769/optimization-of-machining-parametric-study-on-electrical-discharge-machining" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47769.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">331</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">1932</span> An Experimental Investigation of Microscopic and Macroscopic Displacement Behaviors of Branched-Preformed Particle Gel in High Temperature Reservoirs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Weiyao%20Zhu">Weiyao Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Bingbing%20Li"> Bingbing Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Yajing%20Liu"> Yajing Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhiyong%20Song"> Zhiyong Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Branched-preformed particle gel (B-PPG) is a newly developed profile control and oil displacement agent for enhanced oil recovery in major oilfields. To provide a better understanding of the performance of B-PPG in high temperature reservoirs, a comprehensive experimental investigation was conducted by utilizing glass micromodel and synthetic core. The microscopic experimental results show that the B-PPG can selectively flow and plug in large pores. In terms of enhanced oil recovery, the decrease of residual oil in the margin regions (24.6%) was higher than that in the main stream (13.7%), which indicates it enlarged the sweep area. In addition, the effects of B-PPG injection concentration and injection rate on enhanced oil recovery were implemented by core flooding. The macroscopic experimental results indicate that the enhanced oil recovery increased with the increasing of injection concentration. However, the injection rate had a peak value. It is significant to get insight into the behaviors of B-PPG in reservoirs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=branched-preformed%20particle%20gel" title="branched-preformed particle gel">branched-preformed particle gel</a>, <a href="https://publications.waset.org/abstracts/search?q=enhanced%20oil%20recovery" title=" enhanced oil recovery"> enhanced oil recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=micromodel" title=" micromodel"> micromodel</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20flooding" title=" core flooding"> core flooding</a> </p> <a href="https://publications.waset.org/abstracts/78230/an-experimental-investigation-of-microscopic-and-macroscopic-displacement-behaviors-of-branched-preformed-particle-gel-in-high-temperature-reservoirs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78230.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">204</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">1931</span> Entomofauna Biodiversity of a Citrus Orchard in Baraki, Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahlem%20Guerzou">Ahlem Guerzou</a>, <a href="https://publications.waset.org/abstracts/search?q=Salheddine%20Doumandji"> Salheddine Doumandji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Orchards and minimally processed with surrounding hedges form a significant source of biodiversity.

Under the effect of climate change, the approach to climate parameters with precision remains one of the main objectives of the scientific community. This is from the perspective of assessing climate change and its repercussions on humans and the environment. However, many regions of the world suffer from a severe lack of reliable instruments that can make up for this deficit. Alternatively, the use of empirical methods becomes the only way to assess certain parameters that can act as climate indicators. Several scientific methods are used for the evaluation of evapotranspiration which leads to its evaluation either directly at the level of the climatic stations or by empirical methods. All these methods make a point approach and, in no case, allow the spatial variation of this parameter. We, therefore, propose in this paper the use of three sources of information (network of weather stations of Meteo France, World Databases, and Moodis satellite images) to evaluate spatial evapotranspiration (ETP) using the Turc method. This first step will reflect the degree of relevance of the indirect (satellite) methods and their generalization to sites without stations. The spatial variation representation of this parameter using the geographical information system (GIS) accounts for the heterogeneity of the behaviour of this parameter. This heterogeneity is due to the influence of site morphological factors and will make it possible to appreciate the role of certain topographic and hydrological parameters. A phase of predicting the evolution over the medium and long term of evapotranspiration under the effect of climate change by the application of the Intergovernmental Panel on Climate Change (IPCC) scenarios gives a realistic overview as to the contribution of aquatic systems to the scale of the region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=ETP" title=" ETP"> ETP</a>, <a href="https://publications.waset.org/abstracts/search?q=MODIS" title=" MODIS"> MODIS</a>, <a href="https://publications.waset.org/abstracts/search?q=GIEC%20scenarios" title=" GIEC scenarios"> GIEC scenarios</a> </p> <a href="https://publications.waset.org/abstracts/163258/crossing-multi-source-climate-data-to-estimate-the-effects-of-climate-change-on-evapotranspiration-data-application-to-the-french-central-region" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163258.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">107</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">1929</span> A Stable Method for Determination of the Number of Independent Components</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuyan%20Yi">Yuyan Yi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jingyi%20Zheng"> Jingyi Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Nedret%20Billor"> Nedret Billor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Independent component analysis (ICA) is one of the most commonly used blind source separation (BSS) techniques for signal pre-processing, such as noise reduction and feature extraction. The main parameter in the ICA method is the number of independent components (IC). Although there have been several methods for the determination of the number of ICs, it has not been given sufficient attentionto this important parameter. In this study, wereview the mostused methods fordetermining the number of ICs and providetheir advantages and disadvantages. Further, wepropose an improved version of column-wise ICAByBlock method for the determination of the number of ICs.To assess the performance of the proposed method, we compare the column-wise ICAbyBlock with several existing methods through different ICA methods by using simulated and real signal data. Results show that the proposed column-wise ICAbyBlock is an effective and stable method for determining the optimal number of components in ICA. This method is simple, and results can be demonstrated intuitively with good visualizations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=independent%20component%20analysis" title="independent component analysis">independent component analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20number" title=" optimal number"> optimal number</a>, <a href="https://publications.waset.org/abstracts/search?q=column-wise" title=" column-wise"> column-wise</a>, <a href="https://publications.waset.org/abstracts/search?q=correlation%20coefficient" title=" correlation coefficient"> correlation coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=cross-validation" title=" cross-validation"> cross-validation</a>, <a href="https://publications.waset.org/abstracts/search?q=ICAByblock" title=" ICAByblock"> ICAByblock</a> </p> <a href="https://publications.waset.org/abstracts/150582/a-stable-method-for-determination-of-the-number-of-independent-components" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150582.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">104</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">1928</span> Effect of Polymer Concentration on the Rheological Properties of Polyelectrolyte Solutions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Benyounes">Khaled Benyounes</a>, <a href="https://publications.waset.org/abstracts/search?q=Abderrahmane%20Mellak"> Abderrahmane Mellak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The rheology of aqueous solutions of polyelectrolyte (polyanionic cellulose, PAC) at high molecular weight was investigated using a controlled stress rheometer. Several rheological measurements; viscosity measurements, creep compliance tests at a constant low shear stress and oscillation experiments have been performed. The concentrations ranged by weight from 0.01 to 2.5% of PAC. It was found that the aqueous solutions of PAC do not exhibit a yield stress, the flow curves of PAC over a wide range of shear rate (0 to 1000 s-1) could be described by the cross model and the Williamson models. The critical concentrations of polymer c* and c** have been estimated. The dynamic moduli, i.e., storage modulus (G’) and loss modulus (G’’) of the polymer have been determined at frequency sweep from 0.01 to 10 Hz. At polymer concentration above 1%, the modulus G’ is superior to G’’. The relationships between the dynamic modulus and concentration of polymer have been established. The creep-recovery experiments demonstrated that polymer solutions show important viscoelastic properties of system water-PAC when the concentration of the polymer increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polyanionic%20cellulose" title="polyanionic cellulose">polyanionic cellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=viscosity" title=" viscosity"> viscosity</a>, <a href="https://publications.waset.org/abstracts/search?q=creep" title=" creep"> creep</a>, <a href="https://publications.waset.org/abstracts/search?q=oscillation" title=" oscillation"> oscillation</a>, <a href="https://publications.waset.org/abstracts/search?q=cross%20model" title=" cross model"> cross model</a> </p> <a href="https://publications.waset.org/abstracts/6588/effect-of-polymer-concentration-on-the-rheological-properties-of-polyelectrolyte-solutions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6588.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">330</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">1927</span> Evaluation of the Fire Propagation Characteristics of Thermoplastics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ji-Hun%20Choi">Ji-Hun Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyoung-Suk%20Cho"> Kyoung-Suk Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung-Un%20Chae"> Seung-Un Chae</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Consisting of organic compounds, plastic ignites easily and burns fast. In addition, a large amount of toxic gas is produced while it is burning. When plastic is heated, its volume decreases because its surface is melted. The decomposition of its molecular bond generates combustible liquid of low viscosity, which accelerates plastic combustion and spreads the flames. Radiant heat produced in the process propagates the fire to increase the risk of human and property damages. Accordingly, the purpose of this study was to identify chemical, thermal and combustion characteristics of thermoplastic plastics using the fire propagation apparatus based on experimental criteria of ISO 12136 and ASTM E 2058. By the experiment result, as the ignition time increased, the thermal response parameter (TRP) decreased and as the TRP increased, the slope decreased. In other words, the large the TRP was, the longer the time taken for heating and ignition of the material was. It was identified that the fire propagation speed dropped accordingly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire%20propagation%20apparatus%20%28FPA%29" title="fire propagation apparatus (FPA)">fire propagation apparatus (FPA)</a>, <a href="https://publications.waset.org/abstracts/search?q=ISO%2012136" title=" ISO 12136"> ISO 12136</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20response%20parameter%20%28TRP%29" title=" thermal response parameter (TRP)"> thermal response parameter (TRP)</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20propagation%20index%20%28FPI%29" title=" fire propagation index (FPI)"> fire propagation index (FPI)</a> </p> <a href="https://publications.waset.org/abstracts/94397/evaluation-of-the-fire-propagation-characteristics-of-thermoplastics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94397.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">212</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">1926</span> Seismic Assessment of Passive Control Steel Structure with Modified Parameter of Oil Damper</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Naqi">Ahmad Naqi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today, the passively controlled buildings are extensively becoming popular due to its excellent lateral load resistance circumstance. Typically, these buildings are enhanced with a damping device that has high market demand. Some manufacturer falsified the damping device parameter during the production to achieve the market demand. Therefore, this paper evaluates the seismic performance of buildings equipped with damping devices, which their parameter modified to simulate the falsified devices, intentionally. For this purpose, three benchmark buildings of 4-, 10-, and 20-story were selected from JSSI (Japan Society of Seismic Isolation) manual. The buildings are special moment resisting steel frame with oil damper in the longitudinal direction only. For each benchmark buildings, two types of structural elements are designed to resist the lateral load with and without damping devices (hereafter, known as Trimmed & Conventional Building). The target building was modeled using STERA-3D, a finite element based software coded for study purpose. Practicing the software one can develop either three-dimensional Model (3DM) or Lumped Mass model (LMM). Firstly, the seismic performance of 3DM and LMM models was evaluated and found excellent coincide for the target buildings. The simplified model of LMM used in this study to produce 66 cases for both of the buildings. Then, the device parameters were modified by ± 40% and ±20% to predict many possible conditions of falsification. It is verified that the building which is design to sustain the lateral load with support of damping device (Trimmed Building) are much more under threat as a result of device falsification than those building strengthen by damping device (Conventional Building). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=passive%20control%20system" title="passive control system">passive control system</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20damper" title=" oil damper"> oil damper</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20assessment" title=" seismic assessment"> seismic assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=lumped%20mass%20model" title=" lumped mass model"> lumped mass model</a> </p> <a href="https://publications.waset.org/abstracts/108949/seismic-assessment-of-passive-control-steel-structure-with-modified-parameter-of-oil-damper" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108949.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">117</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">1925</span> Pre-Treatment of Anodic Inoculum with Nitroethane to Improve Performance of a Microbial Fuel Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20P.P.">Rajesh P.P.</a>, <a href="https://publications.waset.org/abstracts/search?q=Md.%20Tabish%20Noori"> Md.

Nitroethane is found to be a potent inhibitor of hydrogenotrophic methanogens in rumen fermentation process. Influence of nitroethane pre-treated sewage sludge inoculum on suppressing the methanogenic activity and enhancing the electrogenesis in MFC was evaluated. MFC inoculated with nitroethane pre-treated anodic inoculum demonstrated a maximum operating voltage of 541 mV, with coulombic efficiency and sustainable volumetric power density of 39.85 % and 14.63 W/m3 respectively. Linear sweep voltammetry indicated a higher electron discharge on the anode surface due to enhancement of electrogenic activity while suppressing methanogenic activity. A 63 % reduction in specific methanogenic activity was observed in anaerobic sludge pre-treated with nitroethane; emphasizing significance of this pretreatment for suppressing methanogenesis and its utility for enhancing electricity generation in MFC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coulombic%20efficiency" title="coulombic efficiency">coulombic efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=methanogenesis%20inhibition" title=" methanogenesis inhibition"> methanogenesis inhibition</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20fuel%20cell" title=" microbial fuel cell"> microbial fuel cell</a>, <a href="https://publications.waset.org/abstracts/search?q=nitroethane" title=" nitroethane"> nitroethane</a> </p> <a href="https://publications.waset.org/abstracts/70270/pre-treatment-of-anodic-inoculum-with-nitroethane-to-improve-performance-of-a-microbial-fuel-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70270.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">320</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">1924</span> Ion-Acoustic Double Layers in a Non-Thermal Electronegative Magnetized Plasma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20K.%20Chawla">J.

It is also found that the magnetization affects only the width of the double layer. For a given set of parameter values, increases in the magnetization and the obliqueness angle (θ) between wave vector and magnetic field, affect the width of the double layers, however the amplitude of the double layers have no effect.

There are many transition metal oxides exhibiting electrochromism, e.g. oxides of W, Ni, Ir, V, Ti, Co and Mo. Organic materials especially some conducting polymers such as poly(aniline), poly(3, 4-propylene- dioxythiophene) also received much attention for electrochromic (EC) applications. Electrochromic materials attract considerable interest because of their potential applications, such as information displays, smart windows, variable reflectance mirrors, and variable-emittance thermal radiators. In this study, the EC characteristics are investigated on an all-solid-state EC device composed of a-WO₃ and Ni(OH)₂ with a Ta₂O₅ protective layer which is prepared by magnetron sputtering. It is found that the transmittance modulation increases with decreasing the film thickness of Ta₂O₅. On the other hand, the transmittance modulation is 57% as the Ni(OH)₂/ITO is prepared by the linear-sweep potential cycling of the sputter-deposited Ta₂O₅/NiO/ITO in a 0.5 M LiClO₄+H₂O electrolyte. However, when Ni(OH)₂/ITO is prepared by a 0.01 M HCl electrolyte, the transmittance modulation of EC device can be improved to 61%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochromic%20device" title="electrochromic device">electrochromic device</a>, <a href="https://publications.waset.org/abstracts/search?q=tungsten%20oxide" title=" tungsten oxide"> tungsten oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel" title=" nickel"> nickel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ta%E2%82%82O%E2%82%85" title=" Ta₂O₅"> Ta₂O₅</a> </p> <a href="https://publications.waset.org/abstracts/52520/optical-and-electrochromic-properties-of-all-solid-state-electrochromic-device-consisting-of-amorphous-wo3-and-nioh2" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52520.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">296</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">1922</span> Parametric Appraisal of Robotic Arc Welding of Mild Steel Material by Principal Component Analysis-Fuzzy with Taguchi Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amruta%20Rout">Amruta Rout</a>, <a href="https://publications.waset.org/abstracts/search?q=Golak%20Bihari%20Mahanta"> Golak Bihari Mahanta</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunji%20Bala%20Murali"> Gunji Bala Murali</a>, <a href="https://publications.waset.org/abstracts/search?q=Bibhuti%20Bhusan%20Biswal"> Bibhuti Bhusan Biswal</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20B.%20V.%20L.%20Deepak"> B.

The weld joint parameter and weld process parameter modeling is one of the most crucial aspects of robotic welding. As weld process parameters affect the weld joint parameters differently, a multi-objective optimization technique has to be utilized to obtain optimal setting of weld process parameter. In this paper, a hybrid optimization technique, i.e., Principal Component Analysis (PCA) combined with fuzzy logic has been proposed to get optimal setting of weld process parameters like wire feed rate, welding current. Gas flow rate, welding speed and nozzle tip to plate distance. The weld joint parameters considered for optimization are the depth of penetration, yield strength, and ultimate strength. PCA is a very efficient multi-objective technique for converting the correlated and dependent parameters into uncorrelated and independent variables like the weld joint parameters. Also in this approach, no need for checking the correlation among responses as no individual weight has been assigned to responses. Fuzzy Inference Engine can efficiently consider these aspects into an internal hierarchy of it thereby overcoming various limitations of existing optimization approaches. At last Taguchi method is used to get the optimal setting of weld process parameters. Therefore, it has been concluded the hybrid technique has its own advantages which can be used for quality improvement in industrial applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=robotic%20arc%20welding" title="robotic arc welding">robotic arc welding</a>, <a href="https://publications.waset.org/abstracts/search?q=weld%20process%20parameters" title=" weld process parameters"> weld process parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=weld%20joint%20parameters" title=" weld joint parameters"> weld joint parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=principal%20component%20analysis" title=" principal component analysis"> principal component analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic" title=" fuzzy logic"> fuzzy logic</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20method" title=" Taguchi method"> Taguchi method</a> </p> <a href="https://publications.waset.org/abstracts/87646/parametric-appraisal-of-robotic-arc-welding-of-mild-steel-material-by-principal-component-analysis-fuzzy-with-taguchi-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87646.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">184</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">1921</span> Stagnation-Point Flow towards a Stretching/Shrinking Sheet in a Nanofluid: A Stability Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anuar%20Ishak">Anuar Ishak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The characteristics of stagnation point flow of a nanofluid towards a stretching/shrinking sheet are investigated.

A stability analysis is performed to determine the stability of the dual solutions. It is found that the skin friction decreases when the sheet is stretched, but increases when the suction effect is increased.

Regular testing of the power transformer is very important to maintain the reliability of the power. One of the causes of the failure of the transformer is the breakdown of insulation caused by the presence of voids in the equipment that is electrified. As a result of the voids that occur in this power transformer equipment, it can cause partial discharge. Several methods were used to determine the occurrence of damage to the power transformer equipment, such as Sweep Frequency Response Analysis (SFRA) and Tan Delta. In Inter Bus Transformer (IBT) 500/150 kV Cirata Extra High Voltage (EHV) Substation, a breakdown occurred in the T-phase tertiary bushing. From the lessons learned in this case, a complete electrical test was carried out. From the results of the complete electrical test, there was a suspicion of deterioration in the post-breakdown SFRA results. After overhaul and inspection, traces of voids were found on the tertiary bushing, which indicated a breakdown in the tertiary bushing of the IBT 500/150kV Cirata Substation transformer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=void" title="void">void</a>, <a href="https://publications.waset.org/abstracts/search?q=bushing" title=" bushing"> bushing</a>, <a href="https://publications.waset.org/abstracts/search?q=SFRA" title=" SFRA"> SFRA</a>, <a href="https://publications.waset.org/abstracts/search?q=Tan%20Delta" title=" Tan Delta"> Tan Delta</a> </p> <a href="https://publications.waset.org/abstracts/158237/diagnostic-of-breakdown-in-high-voltage-bushing-power-transformer-500-kv-cirata-substation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158237.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">148</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">1919</span> Vibration and Parametric Instability Analysis of Delaminated Composite Beams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Szekr%C3%A9nyes">A.

It is shown that during the vibration of composite beams the delaminated parts are subjected to the parametric excitation. This can lead to the dynamic buckling during the motion of the structure. The equation of motion includes time-dependent stiffness and so it leads to a system of Mathieu-Hill differential equations. The free vibration analysis of beams is carried out in the usual way by using beam finite elements. The dynamic buckling problem is investigated locally, and the critical buckling forces are determined by the modified harmonic balance method by using an imposed time function of the motion. The stability diagrams are created, and the numerical predictions are compared to experimental results. The most important findings are the critical amplitudes at which delamination buckling takes place, the stability diagrams representing the instability of the system, and the realistic mode shape prediction in contrast with the unrealistic results of models available in the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=delamination" title="delamination">delamination</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20vibration" title=" free vibration"> free vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=parametric%20excitation" title=" parametric excitation"> parametric excitation</a>, <a href="https://publications.waset.org/abstracts/search?q=sweep%20excitation" title=" sweep excitation"> sweep excitation</a> </p> <a href="https://publications.waset.org/abstracts/47603/vibration-and-parametric-instability-analysis-of-delaminated-composite-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47603.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">351</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">1918</span> Performance of CO₂/N₂ Foam in Enhanced Oil Recovery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hassan">Mohamed Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahul%20Gajbhiye"> Rahul Gajbhiye</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The high mobility and gravity override of CO₂ gas can be minimized by generating the CO₂ foam with the aid of surfactant. However, CO₂ is unable to generate the foam/stable foam above its supercritical point (1100 psi, 31°C). These difficulties with CO₂ foam is overcome by adding N₂ in small fraction to enhance the foam generation of CO₂ at supercritical conditions. This study shows how the addition of small quantity of N₂ helps in generating the CO₂ foam and performance of the CO₂/N₂ mixture foam in enhanced oil recovery. To investigate the performance of CO₂/N₂ foam, core-flooding experiments were conducted at elevated pressure and temperature condition (higher than supercritical CO₂ - 50°C and 1500 psi) in sandstone cores. Fluorosurfactant (FS-51) was used as a foaming agent, and n-decane was used as model oil in all the experiments. The selection of foam quality and N₂ fraction was optimized based on foam generation and stability tests. Every gas or foam flooding was preceded by seawater injection to simulate the behavior in the reservoir. The results from the core-flood experiments showed that the CO₂ and CO₂/N₂ foam flooding recovered an additional 34-40% of Original Initial Oil in Place (OIIP) indicating that foam flooding succeeded in producing more oil than pure CO₂ gas injection processes. Additionally, the performance CO₂/N₂ foam injection was better than CO₂ foam injection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%2FN%E2%82%82%20foam" title="CO₂/N₂ foam">CO₂/N₂ foam</a>, <a href="https://publications.waset.org/abstracts/search?q=enhanced%20oil%20recovery%20%28EOR%29" title=" enhanced oil recovery (EOR)"> enhanced oil recovery (EOR)</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20CO%E2%82%82" title=" supercritical CO₂"> supercritical CO₂</a>, <a href="https://publications.waset.org/abstracts/search?q=sweep%20efficiency" title=" sweep efficiency"> sweep efficiency</a> </p> <a href="https://publications.waset.org/abstracts/71419/performance-of-co2n2-foam-in-enhanced-oil-recovery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71419.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">286</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">1917</span> Generalized Hyperbolic Functions: Exponential-Type Quantum Interactions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20Juan%20Pe%C3%B1a">Jose Juan Peña</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20Morales"> J.

In order to transcend the scope of hyperbolic functions, in this work, a kind of generalized q-deformed hyperbolic functions (g q-dhf) is presented. By a suitable transformation, through the q deformation parameter, it is shown that these g q-dhf can be expressed in terms of their corresponding standard ones besides they can be reduced to the sc q-dhf. As a useful application of the proposed approach, and considering a class of exactly solvable multi-parameter exponential-type potentials, some new q-deformed quantum interactions models that can be used as interesting alternative in quantum physics and quantum states are presented. Furthermore, due that quantum potential models are conditioned on the q-dependence of the parameters that characterize to the exponential-type potentials, it is shown that many specific cases of q-deformed potentials are obtained as particular cases from the proposal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diatomic%20molecules" title="diatomic molecules">diatomic molecules</a>, <a href="https://publications.waset.org/abstracts/search?q=exponential-type%20potentials" title=" exponential-type potentials"> exponential-type potentials</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperbolic%20functions" title=" hyperbolic functions"> hyperbolic functions</a>, <a href="https://publications.waset.org/abstracts/search?q=q-deformed%20potentials" title=" q-deformed potentials"> q-deformed potentials</a> </p> <a href="https://publications.waset.org/abstracts/82814/generalized-hyperbolic-functions-exponential-type-quantum-interactions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82814.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">187</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">1916</span> Stepping in Sustainability: Walkability an Upcoming Design Parameter for Transit Based Communities in Lahore, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sadaf%20Saeed">Sadaf Saeed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The consideration of walkability as an urban design parameter in conjunction with transit-oriented development is an established trend in the developed countries but an upcoming trend in developing countries. In Pakistan, the first Bus Rapid Transit (locally called as Metro Bus) has been introduced in the city of Lahore in 2013 where around 40 percent of the riders access to transit stations by walking. To what extent the aspect of walkability has been considered in the local scenario? To address this question, this paper presents an account of urban design parameters regarding pedestrian provisions and quality of walking environment between Metro Bus stations and users’ destination in the transit neighbourhoods (areas up to 500-meter radius). The primary and secondary data for objective and subjective walkability measurements has been used for neighbourhoods of five selected transit stations ranked against the predefined critical assessed factors (CAF). The multi-criteria approach including visual and geospatially-based parameters at street level, along with walkability index score at selected sites linked with CAF evaluation were the selected methods for this study. The acceptability of walkability as an urban design parameter for transit planning in terms of connectivity and social implications of the concept has also been analysed in the local context. The paper highlights that the aspect of walkability in Lahore is being derelict owing to the focus of government on other initiatives such as park and ride and feeder bus services for mobility of passengers. However, the pedestrian-friendly design parameters as a part of future transit planning can enhance social, liveable and interactive walking environment within transit neighbourhoods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=walkability" title="walkability">walkability</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=transit%20neighborhoods" title=" transit neighborhoods"> transit neighborhoods</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20communities" title=" social communities"> social communities</a> </p> <a href="https://publications.waset.org/abstracts/84380/stepping-in-sustainability-walkability-an-upcoming-design-parameter-for-transit-based-communities-in-lahore-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84380.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">248</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">1915</span> The Effect of Degraded Shock Absorbers on the Safety-Critical Tipping and Rolling Behaviour of Passenger Cars</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tobias%20Schramm">Tobias Schramm</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%BCnther%20Prokop"> Günther Prokop</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Germany, the number of road fatalities has been falling since 2010 at a more moderate rate than before. At the same time, the average age of all registered passenger cars in Germany is rising continuously. Studies show that there is a correlation between the age and mileage of passenger cars and the degradation of their chassis components. Various studies show that degraded shock absorbers increase the braking distance of passenger cars and have a negative impact on driving stability. The exact effect of degraded vehicle shock absorbers on road safety is still the subject of research. A shock absorber examination as part of the periodic technical inspection is only mandatory in very few countries. In Germany, there is as yet no requirement for such a shock absorber examination. More comprehensive findings on the effect of degraded shock absorbers on the safety-critical driving dynamics of passenger cars can provide further arguments for the introduction of mandatory shock absorber testing as part of the periodic technical inspection. The specific effect chains of untripped rollover accidents are also still the subject of research. However, current research results show that the high proportion of sport utility vehicles in the vehicle field significantly increases the probability of untripped rollover accidents. The aim of this work is to estimate the effect of degraded twin-tube shock absorbers on the safety-critical tipping and rolling behaviour of passenger cars, which can lead to untripped rollover accidents. A characteristic curve-based five-mass full vehicle model and a semi-physical phenomenological shock absorber model were set up, parameterized and validated. The shock absorber model is able to reproduce the damping characteristics of vehicle twin-tube shock absorbers with oil and gas loss for various excitations. The full vehicle model was validated with steering wheel angle sinus sweep driving maneuvers. The model was then used to simulate steering wheel angle sine and fishhook maneuvers, which investigate the safety-critical tipping and rolling behavior of passenger cars. The simulations were carried out in a realistic parameter space in order to demonstrate the effect of various vehicle characteristics on the effect of degraded shock absorbers. As a result, it was shown that degraded shock absorbers have a negative effect on the tipping and rolling behavior of all passenger cars. Shock absorber degradation leads to a significant increase in the observed roll angles, particularly in the range of the roll natural frequency. This superelevation has a negative effect on the wheel load distribution during the driving maneuvers investigated. In particular, the height of the vehicle's center of gravity and the stabilizer stiffness of the vehicles has a major influence on the effect of degraded shock absorbers on the overturning and rolling behaviour of passenger cars. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title="numerical simulation">numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=safety-critical%20driving%20dynamics" title=" safety-critical driving dynamics"> safety-critical driving dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=suspension%20degradation" title=" suspension degradation"> suspension degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=tipping%20and%20rolling%20behavior%20of%20passenger%20cars" title=" tipping and rolling behavior of passenger cars"> tipping and rolling behavior of passenger cars</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20shock%20absorber" title=" vehicle shock absorber"> vehicle shock absorber</a> </p> <a href="https://publications.waset.org/abstracts/194629/the-effect-of-degraded-shock-absorbers-on-the-safety-critical-tipping-and-rolling-behaviour-of-passenger-cars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194629.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">23</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">1914</span> Segmentation of Piecewise Polynomial Regression Model by Using Reversible Jump MCMC Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suparman">Suparman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Piecewise polynomial regression model is very flexible model for modeling the data.

Three machining parameters namely current (I), spark on time (T<sub>on</sub>) and spark off time (T<sub>off</sub>) are selected as the input variables. The output or response chosen is material removal rate (MRR) which is to be maximized. To reduce the number of runs face centered central composite design (FCCCD) was used. ANOVA was used to determine the significance of parameter and interactions. The suitability of model is tested using Anderson darling (AD) plot. The results conclude that different parameters considered i.e. current, pulse on and pulse off time; all have dominant effect on the MRR.

Long wavelength approximation, Taylor's limiting condition and dynamic boundary conditions at the flexible walls are used to obtain the average effective dispersion coefficient in the presence of combined homogeneous and heterogeneous chemical reactions. The effects of various pertinent parameters on the effective dispersion coefficient are discussed. It is observed that peristalsis enhances dispersion.

However, high mobility ratio and fingering effect are considered as important drawbacka of this process. Low temperature injection of CO<sub>2</sub> into high temperature reservoirs may improve the oil recovery, but simulating multiphase flow in the non-isothermal medium is difficult, and commercial simulators are very unstable in these conditions. Furthermore, to best of authors’ knowledge, no experimental work was done to verify the results of the simulations and to understand the pore-scale process. In this paper, we present results of investigations on injection of low temperature CO<sub>2</sub> into a high-pressure high-temperature micromodel with injection temperature range from 34 to 75 °F. Effect of temperature and saturation changes of different fluids are measured in each case. The results prove the proposed method. The injection of CO<sub>2</sub> at low temperatures increased the oil recovery in high temperature reservoirs significantly. Also, CO<sub>2</sub> rich phases available in the high temperature system can affect the oil recovery through the better sweep of the oil which is initially caused by penetration of LCO<sub>2</sub> inside the system. Furthermore, no unfavorable effect was detected using this method. Low temperature CO<sub>2</sub> is proposed to be used as early as secondary recovery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=enhanced%20oil%20recovery" title="enhanced oil recovery">enhanced oil recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20flooding" title=" CO₂ flooding"> CO₂ flooding</a>, <a href="https://publications.waset.org/abstracts/search?q=micromodel%20studies" title=" micromodel studies"> micromodel studies</a>, <a href="https://publications.waset.org/abstracts/search?q=miscible%20flooding" title=" miscible flooding"> miscible flooding</a> </p> <a href="https://publications.waset.org/abstracts/71727/oil-recovery-study-by-low-temperature-carbon-dioxide-injection-in-high-pressure-high-temperature-micromodels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71727.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">357</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">1908</span> Calibration of Discrete Element Method Parameters for Modelling DRI Pellets Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Hossein%20Madadi-Najafabadi">A.

However, the characteristics and properties of the granules have to be adjusted precisely to achieve reliable results in a DEM simulation. The main properties for DEM simulation are size distribution, density, Young's modulus, Poisson's ratio and the contact coefficients of restitution, rolling friction and sliding friction. In the present paper, the mentioned properties are determined for DEM simulation of DRI pellets. A reliable DEM simulation would contribute to optimizing the handling system of DRIs in an iron-making plant. Among the mentioned properties, Young's modulus is the most important parameter, which is usually hard to get for particulate solids.

The selection of photoresist depends upon many factors such as cost, the thickness of the resist, comfortable and valuable parameters extraction.

It is found that the effects of vehicle frequency, unevenness, and speed on the negative moment dynamic load allowance are significant, among which vehicle frequency has the greatest effect on the negative moment dynamic load allowance; the effects of span number and span diameter on the negative moment dynamic load allowance are relatively small; the effects of forced displacement of the support on the negative moment dynamic load allowance are negligible. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=continuous%20T-girder%20bridge" title="continuous T-girder bridge">continuous T-girder bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20load%20allowance" title=" dynamic load allowance"> dynamic load allowance</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity%20analysis" title=" sensitivity analysis"> sensitivity analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle-bridge%20coupling" title=" vehicle-bridge coupling"> vehicle-bridge coupling</a> </p> <a href="https://publications.waset.org/abstracts/152547/sensitivity-parameter-analysis-of-negative-moment-dynamic-load-allowance-of-continuous-t-girder-bridge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152547.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">166</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">1905</span> Estimating Gait Parameter from Digital RGB Camera Using Real Time AlphaPose Learning Architecture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Murad%20Almadani">Murad Almadani</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalil%20Abu-Hantash"> Khalil Abu-Hantash</a>, <a href="https://publications.waset.org/abstracts/search?q=Xinyu%20Wang"> Xinyu Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Herbert%20Jelinek"> Herbert Jelinek</a>, <a href="https://publications.waset.org/abstracts/search?q=Kinda%20Khalaf"> Kinda Khalaf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gait analysis is used by healthcare professionals as a tool to gain a better understanding of the movement impairment and track progress. In most circumstances, monitoring patients in their real-life environments with low-cost equipment such as cameras and wearable sensors is more important. Inertial sensors, on the other hand, cannot provide enough information on angular dynamics. This research offers a method for tracking 2D joint coordinates using cutting-edge vision algorithms and a single RGB camera. We provide an end-to-end comprehensive deep learning pipeline for marker-less gait parameter estimation, which, to our knowledge, has never been done before. To make our pipeline function in real-time for real-world applications, we leverage the AlphaPose human posture prediction model and a deep learning transformer. We tested our approach on the well-known GPJATK dataset, which produces promising results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gait%20analysis" title="gait analysis">gait analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20pose%20estimation" title=" human pose estimation"> human pose estimation</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=real%20time%20gait%20estimation" title=" real time gait estimation"> real time gait estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=AlphaPose" title=" AlphaPose"> AlphaPose</a>, <a href="https://publications.waset.org/abstracts/search?q=transformer" title=" transformer"> transformer</a> </p> <a href="https://publications.waset.org/abstracts/151203/estimating-gait-parameter-from-digital-rgb-camera-using-real-time-alphapose-learning-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151203.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">123</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">1904</span> Effect of the Tidal Charge Parameter on CMBR Temperature Anisotropies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Evariste%20Boj">Evariste Boj</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Schee"> Jan Schee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present the temperature anisotropy of the cosmic microwave background radiation due to the inhomogeneity region constructed on a 3-brane in the framework of a Randall-Sundrum one brane immersed into a 5D bulk $AdS_5$ spacetime. We employ the Brane-World Friedmann-Lemaitre-Robertson-Walker (FLRW) cosmological model to describe the cosmic expansion on the brane. The inhomogeneity is modeled by the static, spherically symmetric spacetime that replaces the spherically symmetric part of a dust-filled universe and is connected to the FLRW spacetime through the junction conditions. As the vacuum region expands it induces an additional frequency shift to a CMBR photon passing through this inhomogeneity in comparison to the case of a photon propagating through a pure FLRW spacetime. This frequency shift is associated with the effective temperature change of the CMBR in the corresponding direction. We give an estimate of the CMBR effective temperature changes with the change of the value of the tidal charge parameter. <p class="card-text"><strong>Keywords:</strong> <a
