The gas sensing performance of Pd-Pt/p-TiO₂/p-Si sensing electrode towards H₂ gas under low (10-500 ppm) detection limit and operating temperature regime (25-200 °C) was discussed. The sensor is highly sensitive even at room temperature, with response (Ra/Rg) reaching ~102 for 500 ppm H₂ in dry air and its capability of sensing H₂ concentrations as low as ~10 ppm was demonstrated. At elevated temperature of 200 ℃, the response reached more than ~103 for 500 ppm H₂. Overall the fabricated resistive gas sensor exhibited high selectivity, good sensing response, and fast response/recovery time with good stability towards H₂. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sputtering" title="sputtering">sputtering</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20silicon%20%28p-Si%29" title=" porous silicon (p-Si)"> porous silicon (p-Si)</a>, <a href="https://publications.waset.org/abstracts/search?q=TiO%E2%82%82%20thin%20film" title=" TiO₂ thin film"> TiO₂ thin film</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20gas%20sensor" title=" hydrogen gas sensor"> hydrogen gas sensor</a> </p> <a href="https://publications.waset.org/abstracts/93541/a-fast-chemiresistive-h2-gas-sensor-based-on-sputter-grown-nanocrystalline-p-tio2-thin-film-decorated-with-catalytic-pd-pt-layer-on-p-si-substrate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93541.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">258</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">6917</span> Quadriceps Muscle Activity in Response to Slow and Fast Perturbations following Fatiguing Exercise</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nosratollah%20Hedayatpour">Nosratollah Hedayatpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Reza%20Taheri"> Hamid Reza Taheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehrdad%20Fathi"> Mehrdad Fathi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Quadriceps femoris muscle is frequently involved in various movements e.g., jumping, landing) during sport and/or daily activities. During ballistic movement when individuals are faced with unexpected knee perturbation, fast twitch muscle fibers contribute to force production to stabilize knee joint. Fast twitch muscle fiber is more susceptible to fatigue and therefor may reduce the ability of the quadriceps muscle to stabilize knee joint during fast perturbation. Aim: The aim of this study was to investigate the effect of fatigue on postural response of the knee extensor muscles to fast and slow perturbations. Methods: Fatigue was induced to the quadriceps muscle using a KinCom Isokinetic Dynamometer (Chattanooga, TN). Bipolar surface electromyography (EMG) signals were simultaneously recorded from quadriceps components (vastus medialis, rectus femoris, and vastus lateralis) during pre- and post-fatigue postural perturbation performed at two different velocities of 120 ms and 250 mes. Results: One-way ANOVA showed that maximal voluntary knee extension force and time to task failure, and associated EMG activities were significantly reduced after fatiguing knee exercise (P< 0.05). Two-ways ANOVA also showed that ARV of EMG during backward direction was significantly larger than forward direction (P< 0.05), and during fast-perturbation it was significantly higher than slow-perturbation (P< 0.05). Moreover, ARV of EMG was significantly reduced during post fatigue perturbation, with the largest reduction identified for fast-perturbation compared with slow perturbation (P< 0.05). Conclusion: A larger reduction in muscle activity of the quadriceps muscle was observed during post fatigue fast-perturbation to stabilize knee joint, most likely due to preferential recruitment of fast twitch muscle fiber which are more susceptible to fatigue. This may partly explain that why knee injuries is common after fast ballistic movement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electromyography" title="electromyography">electromyography</a>, <a href="https://publications.waset.org/abstracts/search?q=fast-slow%20perturbations" title=" fast-slow perturbations"> fast-slow perturbations</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue" title=" fatigue"> fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=quadriceps%20femoris%20muscle" title=" quadriceps femoris muscle"> quadriceps femoris muscle</a> </p> <a href="https://publications.waset.org/abstracts/10440/quadriceps-muscle-activity-in-response-to-slow-and-fast-perturbations-following-fatiguing-exercise" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10440.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">523</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">6916</span> Dual Active Bridge Converter with Photovoltaic Arrays for DC Microgrids: Design and Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Atef">Ahmed Atef</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Alhasheem"> Mohamed Alhasheem</a>, <a href="https://publications.waset.org/abstracts/search?q=Eman%20Beshr"> Eman Beshr</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, an enhanced DC microgrid design is proposed using the DAB converter as a conversion unit in order to harvest the maximum power from the PV array. Each connected DAB converter is controlled with an enhanced control strategy. The controller is based on the artificial intelligence (AI) technique to regulate the terminal PV voltage through the phase shift angle of each DAB converter. In this manner, no need for a Maximum Power Point Tracking (MPPT) unit to set the reference of the PV terminal voltage. This strategy overcomes the stability issues of the DC microgrid as the response of converters is superior compared to the conventional strategies.

John Arul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In sophisticated and complex systems such as nuclear power plants, maintaining the system's stability in the presence of uncertainties and disturbances and obtaining a fast dynamic response are the most challenging problems. Thus, to ensure the satisfactory and safe operation of nuclear power plants, this work proposes a new fast, robust optimal switching control strategy for pressurized water reactor-type nuclear power plants. The proposed control strategy guarantees a substantial degree of robustness, fast dynamic response over the entire operational envelope, and optimal performance during the nominal operation of the plant. To improve the robustness, obtain a fast dynamic response, and make the system optimal, a bank of controllers is designed. Various controllers, like a baseline proportional-integral-derivative controller, an optimal linear quadratic Gaussian controller, and a robust adaptive L1 controller, are designed to perform distinct tasks in a specific situation. At any instant of time, the most suitable controller from the bank of controllers is selected using the switching logic unit that designates the controller by monitoring the health of the nuclear power plant or transients. The proposed switching control strategy optimizes the overall performance and increases operational safety and efficiency. Simulation studies have been performed considering various uncertainties and disturbances that demonstrate the applicability and effectiveness of the proposed switching control strategy over some conventional control techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=switching%20control" title="switching control">switching control</a>, <a href="https://publications.waset.org/abstracts/search?q=robust%20control" title=" robust control"> robust control</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20control" title=" optimal control"> optimal control</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20power%20control" title=" nuclear power control"> nuclear power control</a> </p> <a href="https://publications.waset.org/abstracts/163571/fast-robust-switching-control-scheme-for-pwr-type-nuclear-power-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163571.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">134</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">6914</span> Simple and Concise Maximum Power Control Circuit for PV Power Generation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Keiju%20Matsui">Keiju Matsui</a>, <a href="https://publications.waset.org/abstracts/search?q=Mikio%20Yasubayashi"> Mikio Yasubayashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Masayoshi%20Umeno"> Masayoshi Umeno</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Consumption of energy is increasing every year, and yet does not the decline at all. The main energy source is fossil fuels such as petroleum and natural gas. Since it is the finite resources, they will be exhausted someday. Moreover, to make the fossil fuel an energy source causes an environment problem. In such way, one solution of the problems is the solar battery that is remarkable as one of the alternative energies. Under such circumstances, in this paper, we propose a novel maximum power control circuit for photovoltaic power generation system with simple and fast-response operation. In addition to an application to the solar battery, since this control system is possible to operate with simple circuit and fast-response, the polar value control like the maximum or the minimum value tracking for general application could be easily realized. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maximum%20power%20control" title="maximum power control">maximum power control</a>, <a href="https://publications.waset.org/abstracts/search?q=inter-connection" title=" inter-connection"> inter-connection</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20power%20generation" title=" photovoltaic power generation"> photovoltaic power generation</a>, <a href="https://publications.waset.org/abstracts/search?q=PI%20controller" title=" PI controller"> PI controller</a>, <a href="https://publications.waset.org/abstracts/search?q=multiplier" title=" multiplier"> multiplier</a>, <a href="https://publications.waset.org/abstracts/search?q=exclusive-or" title=" exclusive-or"> exclusive-or</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20system" title=" power system"> power system</a> </p> <a href="https://publications.waset.org/abstracts/2577/simple-and-concise-maximum-power-control-circuit-for-pv-power-generation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2577.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">441</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">6913</span> A Fast Version of the Generalized Multi-Directional Radon Transform</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ines%20Elouedi">Ines Elouedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Atef%20Hammouda"> Atef Hammouda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a new fast version of the generalized Multi-Directional Radon Transform method.

A mixed method approach was used in this research; basically involving quantitative and qualitative methods. The quantitative method uses a self-completion questionnaire to randomly sample one hundred and four students; while the qualitative method uses a semi structured interview technique to survey four students on their knowledge and choice to consume fast food. A cross tabulation of variables and the Kruskal Wallis nonparametric test were used to analyse the quantitative data; while the qualitative data was analysed through deduction of themes, and trends from the interview transcribe. The findings revealed that globalisation has amplified the evolution of fast food, popularising it among students. Its global presence has affected students’ food choice and preference. Price, convenience, taste, and peer influence are some of the major factors affecting students’ choice of fast food. Though, students are familiar with the health effect of fast food and the significance of using food information labels for healthy choice making, their preference of fast food is more than homemade food. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fast%20food" title="fast food">fast food</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20choice" title=" food choice"> food choice</a>, <a href="https://publications.waset.org/abstracts/search?q=globalisation" title=" globalisation"> globalisation</a>, <a href="https://publications.waset.org/abstracts/search?q=students" title=" students"> students</a> </p> <a href="https://publications.waset.org/abstracts/47399/the-effect-of-fast-food-globalisation-on-students-food-choice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47399.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">291</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">6911</span> Simulation and Characterization of Compact Magnetic Proton Recoil Spectrometer for Fast Neutron Spectra Measurements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xingyu%20Peng">Xingyu Peng</a>, <a href="https://publications.waset.org/abstracts/search?q=Qingyuan%20Hu"> Qingyuan Hu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xuebin%20Zhu"> Xuebin Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xi%20Yuan"> Xi Yuan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Neutron spectrometry has contributed much to the development of nuclear physics since 1932 and has also become an importance tool in several other fields, notably nuclear technology, fusion plasma diagnostics and radiation protection. Compared with neutron fluxes, neutron spectra can provide more detailed information on the internal physical process of neutron sources, such as fast neutron reactors, fusion plasma, fission-fusion hybrid reactors, and so on. However, high performance neutron spectrometer is not so commonly available as it requires the use of large and complex instrumentation. This work describes the development and characterization of a compact magnetic proton recoil (MPR) spectrometer for high-resolution measurements of fast neutron spectra. The compact MPR spectrometer is featured by its large recoil angle, small size permanent analysis magnet, short beam transport line and dual-purpose detector array for both steady state and pulsed neutron spectra measurement. A 3-dimensional electromagnetic particle transport code is developed to simulate the response function of the spectrometer. Simulation results illustrate that the performance of the spectrometer is mainly determined by n-p recoil foil and proton apertures, and an overall energy resolution of 3% is achieved for 14 MeV neutrons. Dedicated experiments using alpha source and mono-energetic neutron beam are employed to verify the simulated response function of the compact MPR spectrometer. These experimental results show a good agreement with the simulated ones, which indicates that the simulation code possesses good accuracy and reliability.

In the present work, microdosimetric response of these detectors to fast neutrons has been investigated by Monte Carlo method. Three similar microdosimeters made of A-150 and rexolite as the wall materials are designed; the first based on single-THGEM, the second based on double-THGEM and the third is based on triple-THGEM. Sensitive volume of the three microdosimeters is a right cylinder of 5 mm height and diameter which is filled with the propane-based tissue-equivalent (TE) gas. The TE gas with 0.11 atm pressure at the room temperature simulates 1 µm of tissue. Lineal energy distributions for several neutron energies from 10 keV to 14 MeV including 241Am-Be neutrons are calculated by the Geant4 simulation toolkit. Also, mean quality factor and dose-equivalent value for any neutron energy has been determined by these distributions. Obtained data derived from the three microdosimeters are in agreement. Therefore, we conclude that the multiple-THGEM structures present similar microdosimetric responses to fast neutrons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fast%20neutrons" title="fast neutrons">fast neutrons</a>, <a href="https://publications.waset.org/abstracts/search?q=geant4" title=" geant4"> geant4</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple-thick%20gas%20electron%20multiplier" title=" multiple-thick gas electron multiplier"> multiple-thick gas electron multiplier</a>, <a href="https://publications.waset.org/abstracts/search?q=microdosimeter" title=" microdosimeter"> microdosimeter</a> </p> <a href="https://publications.waset.org/abstracts/39231/simulation-study-of-multiple-thick-gas-electron-multiplier-based-microdosimeters-for-fast-neutron-measurements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39231.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">350</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">6909</span> Realization of Hybrid Beams Inertial Amplifier</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Somya%20Ranjan%20Patro">Somya Ranjan Patro</a>, <a href="https://publications.waset.org/abstracts/search?q=Abhigna%20Bhatt"> Abhigna Bhatt</a>, <a href="https://publications.waset.org/abstracts/search?q=Arnab%20Banerjee"> Arnab Banerjee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inertial amplifier has recently gained increasing attention as a new mechanism for vibration control of structures. Currently, theoretical investigations are undertaken by researchers to reveal its fundamentals and to understand its underline principles in altering the structural response of structures against dynamic loadings. This paper investigates experimental and analytical studies on the dynamic characteristics of hybrid beam inertial amplifier (HBIA). The analytical formulation of the HBIA has been derived by implementing the spectral element method and rigid body dynamics. This formulation gives the relation between dynamic force and the response of the structure in the frequency domain. Further, for validation of the proposed HBIA, the experiments have been performed. The experimental setup consists of a 3D printed HBIA of polylactic acid (PLA) material screwed at the base plate of the shaker system. Two numbers of accelerometers are used to study the response, one at the base plate of the shaker second one placed at the top of the inertial amplifier. A force transducer is also placed in between the base plate and the inertial amplifier to calculate the total amount of load transferred from the base plate to the inertial amplifier. The obtained time domain response from the accelerometers have been converted into the frequency domain using the Fast Fourier Transform (FFT) algorithm. The experimental transmittance values are successfully validated with the analytical results, providing us essential confidence in our proposed methodology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inertial%20amplifier" title="inertial amplifier">inertial amplifier</a>, <a href="https://publications.waset.org/abstracts/search?q=fast%20fourier%20transform" title=" fast fourier transform"> fast fourier transform</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20frequencies" title=" natural frequencies"> natural frequencies</a>, <a href="https://publications.waset.org/abstracts/search?q=polylactic%20acid" title=" polylactic acid"> polylactic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=transmittance" title=" transmittance"> transmittance</a>, <a href="https://publications.waset.org/abstracts/search?q=vibration%20absorbers" title=" vibration absorbers"> vibration absorbers</a> </p> <a href="https://publications.waset.org/abstracts/153357/realization-of-hybrid-beams-inertial-amplifier" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153357.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">100</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">6908</span> The Response of LCC to DC System Faults and HVDC Re-Establishment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mesbah%20Tarek">Mesbah Tarek</a>, <a href="https://publications.waset.org/abstracts/search?q=Kelaiaia%20Samia"> Kelaiaia Samia</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiheb%20Sofien"> Chiheb Sofien</a>, <a href="https://publications.waset.org/abstracts/search?q=Kelaiaia%20Mounia%20Samira"> Kelaiaia Mounia Samira</a>, <a href="https://publications.waset.org/abstracts/search?q=Labar%20Hocine"> Labar Hocine</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As every power systems short circuit failure can occur for HVDC at the DC link.

In this study, we utilized RNA-Seq to generate a high-resolution transcriptome map of the tomato (Solanum lycopersicum) genome effected by FNI. To quantify the different transcription levels in tomato irradiated by FNI, tomato seeds were irradiated by using MC-50 cyclotron (KIRAMS, Korea) for 0, 30 and 90 minutes, respectively. To investigate the effects on the pre-soaking condition, experimental groups were divided into dry and soaked seeds, which were soaked for 8 hours before irradiation. There was no noticeable difference in the percentage germination (PG) among dry seeds, while irradiated soaked seeds have about 10 % lower PG compared to the unirradiated control group. Using whole transcriptome sequencing by HiSeq 2000, we analyzed the differential gene expression in response to different time of FNI in dry and soaked seeds. More than 1.4 million base pair reads were mapped onto the tomato reference genome and the expression pattern differences between irradiated and unirradiated seeds were assessed. In 0, 30 and 90 minutes irradiation, 12,135, 28,495 and 28,675 transcripts were generated, respectively. Gene ontology analysis suggested the different enrichment of transcripts involved in response to different FNI. The present study showed that FNI effects on plant gene expression, which can become a new parameters for evaluating the responses against FNI on plants. In addition, the comparative analysis of differentially expressed genes in D and S seeds by FNI will also give us a chance to deep explore novel candidate genes for FNI, which could be a good model system to understand the mechanisms behind the adaption of plant to space biology research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tomato%20%28solanum%20lycopersicum%29" title="tomato (solanum lycopersicum)">tomato (solanum lycopersicum)</a>, <a href="https://publications.waset.org/abstracts/search?q=fast%20neutron%20irradiation" title=" fast neutron irradiation"> fast neutron irradiation</a>, <a href="https://publications.waset.org/abstracts/search?q=RNA-sequence" title=" RNA-sequence"> RNA-sequence</a>, <a href="https://publications.waset.org/abstracts/search?q=transcriptome%20expression" title=" transcriptome expression"> transcriptome expression</a> </p> <a href="https://publications.waset.org/abstracts/65369/transcriptome-analysis-of-dry-and-soaked-tomato-solanum-lycopersicum-seeds-in-response-to-fast-neutron-irradiation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65369.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">319</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">6905</span> Study on the Seismic Response of Slope under Pulse-Like Ground Motion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peter%20Antwi%20Buah">Peter Antwi Buah</a>, <a href="https://publications.waset.org/abstracts/search?q=Yingbin%20Zhang"> Yingbin Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianxian%20He"> Jianxian He</a>, <a href="https://publications.waset.org/abstracts/search?q=Chenlin%20Xiang"> Chenlin Xiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Delali%20Atsu%20Y.%20Bakah"> Delali Atsu Y.

The double pulsed pulse-like ground motion is as well known to be stronger than the single pulse. This study has numerically justified this perspective by studying the dynamic response of a homogeneous rock slope subjected to four pulse-like and two non-pulse-like ground motions using the Fast Lagrangian Analysis of Continua in 3 Dimensions (FLAC3D) software. Two of the pulse-like ground motions just have a single pulse. The results show that near-fault ground motions with velocity pulses can cause a higher dynamic response than regular ground motions. The amplification of the peak ground acceleration (PGA) in horizontal direction increases with the increase of the slope elevation. The seismic response of the slope under double pulse ground motion is stronger than that of the single pulse ground motion. The PGV amplification factor under the effect of the non-pulse-like records is also smaller than those under the pulse-like records. The velocity pulse strengthens the earthquake damage to the slope, which results in producing a more strong dynamic response. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=velocity%20pulses" title="velocity pulses">velocity pulses</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20response" title=" dynamic response"> dynamic response</a>, <a href="https://publications.waset.org/abstracts/search?q=PGV%20magnification%20effect" title=" PGV magnification effect"> PGV magnification effect</a>, <a href="https://publications.waset.org/abstracts/search?q=elevation%20effect" title=" elevation effect"> elevation effect</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20pulse" title=" double pulse"> double pulse</a> </p> <a href="https://publications.waset.org/abstracts/144882/study-on-the-seismic-response-of-slope-under-pulse-like-ground-motion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144882.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">176</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">6904</span> [Keynote Speech]: Bridge Damage Detection Using Frequency Response Function</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Noor%20Al-Qayyim">Ahmed Noor Al-Qayyim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the past decades, the bridge structures are considered very important portions of transportation networks, due to the fast urban sprawling.

Simulation results show that the proposed algorithm is robust against parameter uncertainty and has better performance than conventional sliding mode for controlling a quadrotor UAV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quadrotor%20UAV" title="quadrotor UAV">quadrotor UAV</a>, <a href="https://publications.waset.org/abstracts/search?q=fast%20terminal%20sliding%20mode" title=" fast terminal sliding mode"> fast terminal sliding mode</a>, <a href="https://publications.waset.org/abstracts/search?q=second%20order%20sliding%20mode%20t" title=" second order sliding mode t"> second order sliding mode t</a> </p> <a href="https://publications.waset.org/abstracts/16258/fast-terminal-sliding-mode-controller-for-quadrotor-uav" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16258.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">547</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">6900</span> Performance of Coded Multi-Line Copper Wire for G.fast Communications in the Presence of Impulsive Noise</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Israa%20Al-Neami">Israa Al-Neami</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20J.%20Al-Askery"> Ali J.

First, we construct our proposed MLCW channel and verify its characteristics based on the Kolmogorov-Smirnov test. In addition, we apply Middleton class A impulsive noise (IN) to the copper channel for further investigation. Second, the MIMO G.fast system is adopted utilizing the proposed MLCW channel model and is compared to a single line G-fast system. Second, the performance of the coded system is obtained utilizing concatenated interleaved Reed-Solomon (RS) code with four-dimensional trellis-coded modulation (4D TCM), and compared to the single line G-fast system. Simulations are obtained for high quadrature amplitude modulation (QAM) constellations that are commonly used with G-fast communications, the results demonstrate that the bit error rate (BER) performance of the coded MLCW system shows an improvement compared to the single line G-fast systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.fast" title="G.fast">G.fast</a>, <a href="https://publications.waset.org/abstracts/search?q=Middleton%20Class%20A%20impulsive%20noise" title=" Middleton Class A impulsive noise"> Middleton Class A impulsive noise</a>, <a href="https://publications.waset.org/abstracts/search?q=mitigation%20techniques" title=" mitigation techniques"> mitigation techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=Copper%20channel%20model" title=" Copper channel model"> Copper channel model</a> </p> <a href="https://publications.waset.org/abstracts/107793/performance-of-coded-multi-line-copper-wire-for-gfast-communications-in-the-presence-of-impulsive-noise" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107793.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">132</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">6899</span> Influence of Measurement System on Negative Bias Temperature Instability Characterization: Fast BTI vs Conventional BTI vs Fast Wafer Level Reliability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vincent%20King%20Soon%20Wong">Vincent King Soon Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Seng%20Ng"> Hong Seng Ng</a>, <a href="https://publications.waset.org/abstracts/search?q=Florinna%20Sim"> Florinna Sim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Negative Bias Temperature Instability (NBTI) is one of the critical degradation mechanisms in semiconductor device reliability that causes shift in the threshold voltage (Vth). However, thorough understanding of this reliability failure mechanism is still unachievable due to a recovery characteristic known as NBTI recovery. This paper will demonstrate the severity of NBTI recovery as well as one of the effective methods used to mitigate, which is the minimization of measurement system delays. Comparison was done in between two measurement systems that have significant differences in measurement delays to show how NBTI recovery causes result deviations and how fast measurement systems can mitigate NBTI recovery.

But the BNA technique is not very successful in evaluating surface integrity of ground steels that exhibit poor micro-magnetic response. A new approach has been proposed for the processing of BN signal with Fast Fourier transforms while Wavelet transforms has been used to remove noise from the BN signal, with judicious choice of the ‘threshold’ value, when the micro-magnetic response of the work material is poor. In the present study, the effect of down feed induced upon conventional plunge surface grinding of hardened bearing steel has been investigated along with an ultrasonically cleaned, wet polished and a sample ground with spark out technique for benchmarking. Moreover, the FFT analysis has been established, at different sets of applied voltages and applied frequency and the pattern of the BN signal in the frequency domain is analyzed. The study also depicts the wavelet transforms technique with different levels of decomposition and different mother wavelets, which has been used to reduce the noise value in BN signal of materials with poor micro-magnetic response, in order to standardize the procedure for all BN signals depending on the frequency of the applied voltage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=barkhausen%20noise%20analysis" title="barkhausen noise analysis">barkhausen noise analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=grinding" title=" grinding"> grinding</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20properties" title=" magnetic properties"> magnetic properties</a>, <a href="https://publications.waset.org/abstracts/search?q=signal%20processing" title=" signal processing"> signal processing</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-magnetic%20response" title=" micro-magnetic response"> micro-magnetic response</a> </p> <a href="https://publications.waset.org/abstracts/29867/signal-processing-of-barkhausen-noise-signal-for-assessment-of-increasing-down-feed-in-surface-ground-components-with-poor-micro-magnetic-response" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29867.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">667</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">6896</span> Fast Fashion Parallel to Sustainable Fashion in India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saurav%20Sharma">Saurav Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Deepshikha%20Sharma"> Deepshikha Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=Pratibha%20Sharma"> Pratibha Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper includes fast fashion verses sustainable fashion or slow fashion Indian based consumers.

This research taking a holistic view to explore all dimensions of corporate identity and influence of each on customers’ shopping experience in the fast fashion retail sector in the U.K. Unfortunately these issues have not been explored sufficiently in the extant literature, especially in the area of the identity gap. To date, there is still a lack of empirical research on corporate identity, especially in the retail sector despite the importance of the concept to all organisations. Furthermore, although customer group is one of the essential audiences of organisations and the importance of customers in corporate identity management cannot be ignored, to date limited studies have been conducted in order to understand how customers interpret and perceive corporate identity (perceived identity). Therefore, this research investigates customers’ perceptions of corporate identity in the fast fashion retail sector. 1) To explore customers’ perceptions of fast fashion retailers’ corporate identities; 2) To uncover the important constructs of corporate identity which contribute to the U.K. fast fashion retail sector. 40 semi-structured interviews with the fast fashion consumers have been carried out to identify their perceptions of fast fashion retailers' corporate identities. Secondary research on retailers' websites and press releases have been evaluated to identify their desired corporate identities. The findings have revealed that there are significant gaps between how fast fashion retailers present their identities and how their consumers perceive them. This has posed customers' negative perceptions towards the retailers and their shopping experience as a whole. This study has studied how the corporate identity constructs could be applied in the fashion context and has helped retailers to shed lights on how to minimise the gap between desired and perceived identity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate%20identity" title="corporate identity">corporate identity</a>, <a href="https://publications.waset.org/abstracts/search?q=fast%20fashion" title=" fast fashion"> fast fashion</a>, <a href="https://publications.waset.org/abstracts/search?q=fashion%20retailing" title=" fashion retailing"> fashion retailing</a>, <a href="https://publications.waset.org/abstracts/search?q=identity%20gap" title=" identity gap"> identity gap</a> </p> <a href="https://publications.waset.org/abstracts/83265/explore-customers-perceptions-of-uk-fast-fashion-retailers-identities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83265.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">271</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">6894</span> Time-Frequency Modelling and Analysis of Faulty Rotor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20X.%20Tchomeni">B.

The effect of the ensuing non-linear disturbances namely rub and breathing crack is numerically simulated. Subsequently, three analysis methods: Orbit Analysis, Fast Fourier Transform (FFT) and Wavelet Transform (WT) are employed to extract features of the vibration signal of the faulty system. An analysis of the system response orbits clearly indicates the perturbations due to the rotor-to-stator contact. The sensitivities of WT to the variation in system speed have been investigated by Continuous Wavelet Transform (CWT). The analysis reveals that features of crack, rubs and unbalance in vibration response can be useful for condition monitoring. WT reveals its ability to detect non-linear signal, and obtained results provide a useful tool method for detecting machinery faults. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Continuous%20wavelet" title="Continuous wavelet">Continuous wavelet</a>, <a href="https://publications.waset.org/abstracts/search?q=crack" title=" crack"> crack</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20wavelet" title=" discrete wavelet"> discrete wavelet</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20acceleration" title=" high acceleration"> high acceleration</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20acceleration" title=" low acceleration"> low acceleration</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear" title=" nonlinear"> nonlinear</a>, <a href="https://publications.waset.org/abstracts/search?q=rotor-stator" title=" rotor-stator"> rotor-stator</a>, <a href="https://publications.waset.org/abstracts/search?q=rub" title=" rub"> rub</a> </p> <a href="https://publications.waset.org/abstracts/33449/time-frequency-modelling-and-analysis-of-faulty-rotor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33449.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">348</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">6893</span> A Comparative Evaluation on the Quality of Products and Quality of Services of the Five Selected Fast Food Restaurants in Manila</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Pagasa%20Nanette%20Rotairo">M.

The gas sensing performance of sputter made Pd-Pt/ZnO electrode on anodized porous silicon (PSi) substrate toward H₂ gas is studied under low detection limit (2–500 ppm) of H₂ in the air. The chemiresistive sensor demonstrated sublimate selectivity, good sensing response, and fast response/recovery time with excellent stability towards H₂ at low temperature operation under ambient environment. The elaborate selective measurement of Pd-Pt/ZnO/PSi structure was performed towards different oxidizing and reducing gases. This structure exhibited advance and reversible response to H₂ gas, which revealed that the acquired architecture with ZnO framework is a promising candidate for H₂ gas sensor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sputtering" title="sputtering">sputtering</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20silicon" title=" porous silicon"> porous silicon</a>, <a href="https://publications.waset.org/abstracts/search?q=ZnO%20framework" title=" ZnO framework"> ZnO framework</a>, <a href="https://publications.waset.org/abstracts/search?q=XPS%20spectra" title=" XPS spectra"> XPS spectra</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20sensor" title=" gas sensor"> gas sensor</a> </p> <a href="https://publications.waset.org/abstracts/93220/a-facile-and-room-temperature-growth-of-pd-pt-decorated-hexagonal-zno-framework-and-their-selective-h2-gas-sensing-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93220.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">392</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">6891</span> Improvement Perturb and Observe for a Fast Response MPPT Applied to Photovoltaic Panel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Labar%20Hocine">Labar Hocine</a>, <a href="https://publications.waset.org/abstracts/search?q=Kelaiaia%20Mounia%20Samira"> Kelaiaia Mounia Samira</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesbah%20Tarek"> Mesbah Tarek</a>, <a href="https://publications.waset.org/abstracts/search?q=Kelaiaia%20Samia"> Kelaiaia Samia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Maximum power point tracking (MPPT) techniques are used in photovoltaic (PV) systems to maximize the PV array output power by tracking continuously the maximum power point(MPP) which depends on panels temperature and on irradiance conditions. The main drawback of P&O is that, the operating point oscillates around the MPP giving rise to the waste of some amount of available energy; moreover, it is well known that the P&O algorithm can be confused during those time intervals characterized by rapidly changing atmospheric conditions. In this paper, it is shown that in order to limit the negative effects associated to the above drawbacks, the P&O MPPT parameters must be customized to the dynamic behavior of the specific converter adopted. A theoretical analysis allowing the optimal choice of such initial set parameters is also carried out. The fast convergence of the proposal is proven. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=P%26O" title="P&O">P&O</a>, <a href="https://publications.waset.org/abstracts/search?q=Taylor%E2%80%99s%20series" title=" Taylor’s series"> Taylor’s series</a>, <a href="https://publications.waset.org/abstracts/search?q=MPPT" title=" MPPT"> MPPT</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20panel" title=" photovoltaic panel "> photovoltaic panel </a> </p> <a href="https://publications.waset.org/abstracts/21985/improvement-perturb-and-observe-for-a-fast-response-mppt-applied-to-photovoltaic-panel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21985.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">587</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">6890</span> Prevalence of Obesity in Kuwait: A Case Study among Kuwait University Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Alnasrallah">Mohammad Alnasrallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Almatar"> Muhammad Almatar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study seeks to understand the relationship between the effect of geography and obesity prevalence among Kuwait University students. The sample involved 735 participants, 231 male, and 504 females, where there is a high percentage of them are overweight and obese. The percentage of overweight is 21% (BMI >25 - 30) while the percentage of obesity is 13.7% (BMI > 30). Both overweight and obese people account for 34.7%. In the study area, there are 327 fast food restaurants located in different places of in the urban area. This study uses the Geographic Information System to analyze the distribution of obesity and fast food restaurants. The study found that within half kilometers of fast food outlets, there are 33% of normal weight (BMI < 25), 30% of overweight while for the obese people there are 43 %, which shows that obesity is linked to the location of fast food restaurants. One of the significant tools that were used in this study hot and cold spots. The study found that areas of hot spots of fast food restaurants tend to be located in areas of hot spots of obese people. In conclusion, studying the prevalence of obesity from geographical perspective help to understand this public health issue and its relation to the effect of geography. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=obesity%20prevalence" title="obesity prevalence">obesity prevalence</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=fast%20food" title=" fast food"> fast food</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuwait" title=" Kuwait"> Kuwait</a> </p> <a href="https://publications.waset.org/abstracts/97952/prevalence-of-obesity-in-kuwait-a-case-study-among-kuwait-university-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97952.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">215</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">6889</span> ESS Control Strategy for Primary Frequency Response in Microgrid Considering Ramp Rate </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ho-Jun%20Jo">Ho-Jun Jo</a>, <a href="https://publications.waset.org/abstracts/search?q=Wook-Won%20Kim"> Wook-Won Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Sung%20Kim"> Yong-Sung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin-O%20Kim"> Jin-O Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The application of ESS (Energy Storage Systems) in the future grids has been the solution of the microgrid. However, high investment costs necessitate accurate modeling and control strategy of ESS to justify its economic viability and further underutilization. Therefore, the reasonable control strategy for ESS which is subjected to generator and usage helps to curtail the cost of investment and operation costs. The rated frequency in power system is decreased when the load is increasing unexpectedly; hence the thermal power is operated at the capacity of only its 95% for the Governor Free (GF) to adjust the frequency as reserve (5%) in practice. The ESS can be utilized with governor at the same time for the frequency response due to characteristic of its fast response speed and moreover, the cost of ESS is declined rapidly to the reasonable price. This paper presents the ESS control strategy to extend usage of the ESS taken account into governor’s ramp rate and reduce the governor’s intervention as well. All results in this paper are simulated by MATLAB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=micro%20grid" title="micro grid">micro
