A dynamic unstructured tetrahedral mesh approach is accomplished by using three grid sizes to numerically solving the discretized three dimensional, inviscid and compressible Navier-stokes equations. The method used for computations of separation of an external store assuming quasi-steady flow condition. Computations of quasi-steady flow have been directly coupled to a six degree-of-freedom (6DOF) rigid-body motion code to generate store trajectories.

Unfortunately, spammers generate and post fake reviews in order to promote or demote brands and mislead potential customers. These are notably destructive not only for potential customers but also for business holders and manufacturers. However, research in this area is not adequate, and many critical problems related to spam detection have not been solved to date. To provide green researchers in the domain with a great aid, in this paper, we have attempted to create a high-quality framework to make a clear vision on review spam-detection methods. In addition, this report contains a comprehensive collection of detection metrics used in proposed spam-detection approaches.

However, this type of motion is seen with a very complex dimensional data as well as body position, orientation, and joint rotation. Integrated Style Motion Editor (ISME), on the other hand, is a method used to alter the 3D humanoid motion capture data utilised in computer animation and games development. Therefore, this study was carried out with the purpose of demonstrating a method that is able to manipulate and deform different motion styles by integrating Key Pose Deformation Technique and Trajectory Control Technique. This motion editing method allows the user to generate new motions from the original motion capture data using a simple interface control. Unlike the previous method, our method produces a realistic humanoid motion style in real time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer%20animation" title="computer animation">computer animation</a>, <a href="https://publications.waset.org/abstracts/search?q=humanoid%20motion" title=" humanoid motion"> humanoid motion</a>, <a href="https://publications.waset.org/abstracts/search?q=motion%20capture" title=" motion capture"> motion capture</a>, <a href="https://publications.waset.org/abstracts/search?q=motion%20editing" title=" motion editing"> motion editing</a> </p> <a href="https://publications.waset.org/abstracts/54401/isme-integrated-style-motion-editor-for-3d-humanoid-character" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54401.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">382</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">312</span> The Impact of Environmental Dynamism on Strategic Outsourcing Success</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Ghozali%20Hassan">Mohamad Ghozali Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Aziz%20Othman"> Abdul Aziz Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Azril%20Ismail"> Mohd Azril Ismail</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Adapting quickly to environmental dynamism is essential for an organization to develop outsourcing strategic and management in order to sustain competitive advantage.

Non-renewable energy sources cause serious environmental problems with the increase of greenhouse gases. Obtaining energy from renewable sources is also essential for sustainable economic growth. Solar energy is also an important renewable energy source with its unlimited and clean features. In this study, the effect of 1, 2, and 3 layers of perovskite film number and antisolvent dripping on perovskite based solar cell efficiency was investigated. The yield increased as the number of perovskite films increased. In addition, the yields obtained with the antisolvent dripped in the last 5 seconds are higher than the ones dropped in the last 17 seconds. The highest efficiency was obtained with 3 perovskite films, and antisolvent dropped in the last 5 seconds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antisolvent" title="antisolvent">antisolvent</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=perovskite" title=" perovskite"> perovskite</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20cell" title=" solar cell"> solar cell</a> </p> <a href="https://publications.waset.org/abstracts/155240/number-of-perovskite-layers-and-the-effect-of-antisolvent-on-perovskite-solar-cell-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155240.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">109</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">310</span> A New Full Adder Cell for High Performance Low Power Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdiar%20Hosseighadiry">Mahdiar Hosseighadiry</a>, <a href="https://publications.waset.org/abstracts/search?q=Farnaz%20Fotovatikhah"> Farnaz Fotovatikhah</a>, <a href="https://publications.waset.org/abstracts/search?q=Razali%20Ismail"> Razali Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Khaledian"> Mohsen Khaledian</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Saeidemanesh"> Mehdi Saeidemanesh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a new low-power high-performance full adder is presented based on a new design method. The proposed method relies on pass gate design and provides full-swing circuits with minimum number of transistors. The method has been applied on SUM, COUT and XOR-XNOR modules resulting on rail-to-rail intermediate and output signals with no feedback transistors. The presented full adder cell has been simulated in 45 and 32 nm CMOS technologies using HSPICE considering parasitic capacitance and compared to several well-known designs from literature. In addition, the proposed cell has been extensively evaluated with different output loads, supply voltages, temperatures, threshold voltages, and operating frequencies.

This paper presents a detailed mathematical model in order to determine the required reflection phase values from individual element of a reflect array designed in Ku-band frequency range. The proposed technique of obtaining reflection phase can be applied for any geometrical design of elements and is independent of number of array elements. Moreover the model also deals with the solution of reflect array antenna design with both centre and off-set feed configurations. The theoretical modeling has also been implemented for reflect arrays constructed on 0.508 mm thickness of different dielectric substrates. The results show an increase in the slope of the phase curve from 4.61°/mm to 22.35°/mm by varying the material properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mathematical%20modeling" title="mathematical modeling">mathematical modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=progressive%20phase%20distribution" title=" progressive phase distribution"> progressive phase distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=reflect%20array%20antenna" title=" reflect array antenna"> reflect array antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=reflection%20phase" title=" reflection phase"> reflection phase</a> </p> <a href="https://publications.waset.org/abstracts/1426/mathematical-model-for-progressive-phase-distribution-of-ku-band-reflectarray-antennas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1426.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">383</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">308</span> One Step Green Synthesis of Silver Nanoparticles and Their Biological Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samy%20M.%20Shaban">Samy M.

Despite the diversity of culture, customs and beliefs, respectively, Malaysia still be able to stand as a harmonious country. However, if there is an attitude of stereotypes, prejudice and discrimination among ethnic, it may seriously affect the solidarity between people in Malaysia. Thus, this study focuses on constructing a scale measuring the Malaysian experience, strategy and effect of ethnic discrimination. To develop a quantitative measure on ethnic discrimination directed against Malaysian, a three-step process is proposed: Exploratory factor analysis, validity analysis, and internal consistency reliability analysis. Results, limitations, and implications of the study are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=test%20development" title="test development">test development</a>, <a href="https://publications.waset.org/abstracts/search?q=Malaysian%20multi-ethnic%20discrimination%20scale" title=" Malaysian multi-ethnic discrimination scale"> Malaysian multi-ethnic discrimination scale</a>, <a href="https://publications.waset.org/abstracts/search?q=exploratory%20factor%20analysis" title=" exploratory factor analysis"> exploratory factor analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=validity" title=" validity"> validity</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-ethnic" title=" multi-ethnic"> multi-ethnic</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability" title=" reliability"> reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=psychometrics" title=" psychometrics"> psychometrics</a> </p> <a href="https://publications.waset.org/abstracts/15972/development-and-psychometric-evaluation-of-the-malaysian-multi-ethnic-discrimination-scale" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15972.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">742</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">306</span> Investigating Medical Students’ Perspectives toward University Teachers’ Talking Features in an English as a Foreign Language Context in Urmia, Iran </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Baniadam">Ismail Baniadam</a>, <a href="https://publications.waset.org/abstracts/search?q=Nafisa%20Tadayyon"> Nafisa Tadayyon</a>, <a href="https://publications.waset.org/abstracts/search?q=Javid%20Fereidoni"> Javid Fereidoni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to investigate medical students’ attitudes toward some teachers’ talking features regarding their gender in the Iranian context.

Therefore, it is important to protect and restore these historical structures. The aim of this study is to determine the weathering conditions at the Kilistra ancient city. It is located in the southwest of the Konya city, Central Anatolia, and was built by carving into pyroclastic rocks during the Byzantine Era. For this purpose, the petrographic and mechanical properties of the pyroclastic rocks were determined. In the assessment of weathering of structures in the ancient city, in-situ non-destructive testing (i.e., Schmidt hardness rebound value, relative humidity measurement) methods were applied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cultural%20heritage" title="cultural heritage">cultural heritage</a>, <a href="https://publications.waset.org/abstracts/search?q=Kilistra%20ancient%20city" title=" Kilistra ancient city"> Kilistra ancient city</a>, <a href="https://publications.waset.org/abstracts/search?q=non-destructive%20techniques" title=" non-destructive techniques"> non-destructive techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=weathering" title=" weathering"> weathering</a> </p> <a href="https://publications.waset.org/abstracts/63339/determination-of-weathering-at-kilistra-ancient-city-by-using-non-destructive-techniques-central-anatolia-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63339.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">359</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">304</span> Experimental Investigation on Tsunami Acting on Bridges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iman%20Mazinani">Iman Mazinani</a>, <a href="https://publications.waset.org/abstracts/search?q=Zubaidah%20Ismail"> Zubaidah Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Mustafa%20Hashim"> Ahmad Mustafa Hashim</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Reza%20Saba"> Amir Reza Saba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two tragic tsunamis that devastated the west coast of Sumatra Island, Indonesia in 2004 and North East Japan in 2011 had damaged bridges to various extents. Tsunamis have resulted in the catastrophic deterioration of infrastructures i.e. coastal structures, utilities and transportation facilities. A bridge structure performs vital roles to enable people to perform activities related to their daily needs and for development. A damaged bridge needs to be repaired expeditiously. In order to understand the effects of tsunami forces on bridges, experimental tests are carried out to measure the characteristics of hydrodynamic force at various wave heights. Coastal bridge models designed at a 1:40 scale are used in a 24.0 m long hydraulic flume with a cross section of 1.5 m by 2.0 m. The horizontal forces and uplift forces in all cases show that forces increase nonlinearly with increasing wave amplitude. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tsunami" title="tsunami">tsunami</a>, <a href="https://publications.waset.org/abstracts/search?q=bridge" title=" bridge"> bridge</a>, <a href="https://publications.waset.org/abstracts/search?q=horizontal%20force" title=" horizontal force"> horizontal force</a>, <a href="https://publications.waset.org/abstracts/search?q=uplift%20force" title=" uplift force"> uplift force</a> </p> <a href="https://publications.waset.org/abstracts/14510/experimental-investigation-on-tsunami-acting-on-bridges" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14510.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">305</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">303</span> Positive Effects of Natural Gas Usage on Air Pollution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Becenen">Ismail Becenen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Air pollution, a consequence of urbanization brought about by modern life, is as global as it is local and regional. Because of the adverse effects of air pollution on human health, air quality is given importance all over the world. According to the decision of the World Health Organization, clean air is the basic necessity for human health and well-being. It poses a very high risk especially for heart diseases and stroke cases. In this study, the positive effects of natural gas usage on air pollution in cities are explained by using literature scans and air pollution measurement values. Natural gas is cleaner than other types of fuel. It contains less sulfur and organic sulfur compounds. When natural gas burns, it does not leave ashes, it does not cause problems in the rubbish mountains. It's a clean fuel, it easily burns and shines. It is a burning gas that is easy and efficient. In addition, there is not a toxic effect for people in case of inhalation. As a result, the use of natural gas needs to be widespread to reduce air pollution around the world in order to provide a healthier life for people and the environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=natural%20gas" title="natural gas">natural gas</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20pollution" title=" air pollution"> air pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfur%20dioxide" title=" sulfur dioxide"> sulfur dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=particulate%20matter" title=" particulate matter"> particulate matter</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a> </p> <a href="https://publications.waset.org/abstracts/83426/positive-effects-of-natural-gas-usage-on-air-pollution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83426.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">196</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">302</span> Design and Development of a Bi-Leaflet Pulmonary Valve</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Munirah%20Ismail">Munirah Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Joon%20Hock%20Yeo"> Joon Hock Yeo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Paediatric patients who require ventricular outflow tract reconstruction usually need valve construction to prevent valvular regurgitation. They would face problems like lack of suitable, affordable conduits and the need to undergo several operations in their lifetime due to the short lifespan of existing valves. Their natural growth and development are also of concern, even if they manage to receive suitable conduits. Current prosthesis including homografts, bioprosthetic valves, mechanical valves, and bovine jugular veins either do not have the long-term durability or the ability to adapt to the growth of such patients. We have developed a new design of bi-leaflet valve. This new technique accommodates patients’ annular size growth while maintaining valvular patency. A mock circulatory system was set up to assess the hemodynamic performance of the bi-leaflet pulmonary valve. It was found that the percentage regurgitation was acceptable and thus, validates this novel concept. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bi-leaflet%20pulmonary%20valve" title="bi-leaflet pulmonary valve">bi-leaflet pulmonary valve</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20heart%20valve" title=" pulmonary heart valve"> pulmonary heart valve</a>, <a href="https://publications.waset.org/abstracts/search?q=tetralogy%20of%20fallot" title=" tetralogy of fallot"> tetralogy of fallot</a>, <a href="https://publications.waset.org/abstracts/search?q=mock%20circulatory%20system" title=" mock circulatory system"> mock circulatory system</a> </p> <a href="https://publications.waset.org/abstracts/86147/design-and-development-of-a-bi-leaflet-pulmonary-valve" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86147.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">162</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">301</span> A Boundary Fitted Nested Grid Model for Tsunami Computation along Penang Island in Peninsular Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Fazlul%20Karim">Md.

In the presence of a curvilinear coastline, boundary fitted grids are suitable to represent the model boundaries accurately. On the other hand, when large gradient of velocity within a confined area is expected, the use of a nested grid system is appropriate to improve the numerical accuracy with the least grid numbers.

This method provides a reduced permutation and increased convergence speed comparing to the full-band algorithm. Recently, some structures have been suggested to deal with two problems: reducing permutation and increasing the speed of convergence of the adaptive algorithm for correlated input signals. The permutation problem is avoided with the use of adaptive filters of orders less than the full-band adaptive filter, which operate at a sampling rate lower than the sampling rate of the input signal. The decomposed signals by analysis bank filter are less correlated in each sub-band than the input signal at full-band, and can promote better rates of convergence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Blind%20source%20separation" title="Blind source separation">Blind source separation</a>, <a href="https://publications.waset.org/abstracts/search?q=estimates" title=" estimates"> estimates</a>, <a href="https://publications.waset.org/abstracts/search?q=full-band" title=" full-band"> full-band</a>, <a href="https://publications.waset.org/abstracts/search?q=mixtures" title=" mixtures"> mixtures</a>, <a href="https://publications.waset.org/abstracts/search?q=sub-band" title=" sub-band"> sub-band</a> </p> <a href="https://publications.waset.org/abstracts/8254/an-efficient-separation-for-convolutive-mixtures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8254.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">444</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">299</span> Design and Development of an Expanded Polytetrafluoroethylene Valved Conduit with Sinus of Valsalva</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Munirah%20Ismail">Munirah Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Joon%20Hock%20Yeo"> Joon Hock Yeo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Babies born with Tetralogy of Fallot, a congenital heart defect, are required to undergo reconstruction surgery to create a valved conduit. As the child matures, the partially reconstructed pulmonary conduit increases in diameter, while the size of the reconstructed valve remains the same. As a result, follow up surgery is required to replace the undersized valve. Thus, in this project, we evaluated the in-vitro performance of a bi-leaflet valve design in terms of percentage regurgitation with increasing artery (conduit) diameters. Results revealed percentage regurgitations ranging from 13% to 34% for conduits tested. It was observed that percentage of regurgitation increased exponentially with increasing diameters. While the amount of regurgitation may seem severe, it is deemed acceptable, and this valve could potentially reduce the frequency of re-operation in the lifetime of pediatric patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20heart%20valve" title="pulmonary heart valve">pulmonary heart valve</a>, <a href="https://publications.waset.org/abstracts/search?q=tetralogy%20of%20fallot" title=" tetralogy of fallot"> tetralogy of fallot</a>, <a href="https://publications.waset.org/abstracts/search?q=expanded%20polytetrafluoroethylene%20valve" title=" expanded polytetrafluoroethylene valve"> expanded polytetrafluoroethylene valve</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatric%20heart%20valve%20replacement" title=" pediatric heart valve replacement"> pediatric heart valve replacement</a> </p> <a href="https://publications.waset.org/abstracts/86145/design-and-development-of-an-expanded-polytetrafluoroethylene-valved-conduit-with-sinus-of-valsalva" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86145.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">173</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">298</span> 1 kW Power Factor Correction Soft Switching Boost Converter with an Active Snubber Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yakup%20Sahin">Yakup Sahin</a>, <a href="https://publications.waset.org/abstracts/search?q=Naim%20Suleyman%20Ting"> Naim Suleyman Ting</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Aksoy"> Ismail Aksoy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A 1 kW power factor correction boost converter with an active snubber cell is presented in this paper.

The most abundant compound released was dimethyl disulfide. Potential health risk of exposure to this compound is represented by hazard ratio, HR, calculated at 1.6 x 1011. Since HR equal to or less than 1.0 is considered negligible risk, this indicates that the compound posed a potential risk to human health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=volatile%20organic%20compounds" title="volatile organic compounds">volatile organic compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=decomposition%20process" title=" decomposition process"> decomposition process</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20waste" title=" food waste"> food waste</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20risk" title=" health risk"> health risk</a> </p> <a href="https://publications.waset.org/abstracts/39703/volatile-organic-compounds-from-decomposition-of-local-food-waste-and-potential-health-risk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39703.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">520</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">295</span> Evaluation of Transfer Capability Considering Uncertainties of System Operating Condition and System Cascading Collapse</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nur%20Ashida%20Salim">Nur Ashida Salim</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Murtadha%20Othman"> Muhammad Murtadha Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Musirin"> Ismail Musirin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Salleh%20Serwan"> Mohd Salleh Serwan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over the past few decades, the power system industry in many developing and developed countries has gone through a restructuring process of the industry where they are moving towards a deregulated power industry. This situation will lead to competition among the generation and distribution companies to achieve a certain objective which is to provide quality and efficient production of electric energy, which will reduce the price of electricity. Therefore it is important to obtain an accurate value of the Available Transfer Capability (ATC) and Transmission Reliability Margin (TRM) in order to ensure the effective power transfer between areas during the occurrence of uncertainties in the system. In this paper, the TRM and ATC is determined by taking into consideration the uncertainties of the system operating condition and system cascading collapse by applying the bootstrap technique. A case study of the IEEE RTS-79 is employed to verify the robustness of the technique proposed in the determination of TRM and ATC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=available%20transfer%20capability" title="available transfer capability">available transfer capability</a>, <a href="https://publications.waset.org/abstracts/search?q=bootstrap%20technique" title=" bootstrap technique"> bootstrap technique</a>, <a href="https://publications.waset.org/abstracts/search?q=cascading%20collapse" title=" cascading collapse"> cascading collapse</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20reliability%20margin" title=" transmission reliability margin"> transmission reliability margin</a> </p> <a href="https://publications.waset.org/abstracts/4347/evaluation-of-transfer-capability-considering-uncertainties-of-system-operating-condition-and-system-cascading-collapse" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4347.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">408</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">294</span> Corporate Governance and Firm Performance in the UAE</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bakr%20Ali%20Al-Gamrh">Bakr Ali Al-Gamrh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ku%20Nor%20Izah%20B.%20Ku%20Ismail"> Ku Nor Izah B.

We use a firm level panel that spans the period 2008 to 2012 of all listed firms on Abu Dhabi Stock Exchange and Dubai Financial Market. After constructing an index of corporate governance strength, we find a negative effect of corporate governance on firm performance. We, however, discover that corporate governance strength indirectly improves the negative influence of leverage on firm performance in normal times. On the contrary, the results completely reversed when there is a black swan event. Corporate governance strength plays a significantly negative role in moderating the relationship between leverage and firm performance during the financial crisis. We also reveal that corporate governance strength increases firms’ risk and deteriorates performance during crisis.

Thus, we can control air vehicles from ground without pilots in them: The UAVs. Due to UAV’s lack of need of pilots and their small size make them have crucial importance for us. UAVs have variety of usage area, especially in military. However, as soldiers we believe that we can use UAVs for better purposes. In this essay we indicate the usage of UAVs for the sake of saving nature from destruction of disasters by expressing what happened in the past and what can possibly happen in the future, especially in firefighting, preventing avalanches and decreasing the effects of floods. These three disasters cause hazardous consequences to the nature. Wildfires endanger so many lives by burning and destroying what comes in their paths. The numbers of avalanches are increased with the global warming. The changes of seasons triggered floods all over the world that threaten the city life. Besides all of these people may lose their lives in order to intrude these disasters. Drones will do the job without involving people lives. Thus it will diminish the risks so drones will be used for the sake of nature and people. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unmanned%20air%20vehicles" title="unmanned air vehicles">unmanned air vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=nature" title=" nature"> nature</a>, <a href="https://publications.waset.org/abstracts/search?q=firefighting" title=" firefighting"> firefighting</a>, <a href="https://publications.waset.org/abstracts/search?q=avalanche" title=" avalanche"> avalanche</a>, <a href="https://publications.waset.org/abstracts/search?q=flood" title=" flood "> flood </a> </p> <a href="https://publications.waset.org/abstracts/29827/unmanned-air-vehicles-against-disasters-wildfires-avalanches-floods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29827.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">444</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">292</span> Bit Error Rate (BER) Performance of Coherent Homodyne BPSK-OCDMA Network for Multimedia Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Morsy%20Ahmed%20Morsy%20Ismail">Morsy Ahmed Morsy Ismail</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the structure of a coherent homodyne receiver for the Binary Phase Shift Keying (BPSK) Optical Code Division Multiple Access (OCDMA) network is introduced based on the Multi-Length Weighted Modified Prime Code (ML-WMPC) for multimedia applications.

Our objective is to calculate the temperature distribution and the nerve lesion size in a nonhomogenous medium surrounding the RF electrode. A two 3-D finite element models are used to compare the temperature distribution in the homogeneous and nonhomogeneous medium. Also the effect of temperature-dependent electric conductivity on maximum temperature and lesion size is observed.

Mechanical properties of the nanocomposites improved with addition of all three HNTs, but CLA based nanocomposites exhibited a significant enhancement compared to the other HNTs. For instance, tensile properties of EPDM nanocomposites increased by 120%, 256% and 340% for MB, JA, and CLA, respectively with addition of 15 phr of HNTs. This could be due to the higher aspect ratio and higher surface area of CLA compared to others. Scanning electron microscopy (SEM) of nanocomposites at 15 phr of HNT loadings showed low amounts of pulled-out nanotubes which confirmed the presence of more embedded nanotubes inside the EPDM matrix, as well as aggregates within the fracture surface of EPDM/HNT nanocomposites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aspect%20ratio" title="aspect ratio">aspect ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=halloysite%20nanotubes%20%28HNTs%29" title=" halloysite nanotubes (HNTs)"> halloysite nanotubes (HNTs)</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=rubber%2Fclay%20nanocomposites" title=" rubber/clay nanocomposites"> rubber/clay nanocomposites</a> </p> <a href="https://publications.waset.org/abstracts/17259/the-role-of-halloysites-surface-area-and-aspect-ratio-on-tensile-properties-of-ethylene-propylene-diene-monomer-nanocomposites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17259.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">375</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">286</span> Hybrid Robust Estimation via Median Filter and Wavelet Thresholding with Automatic Boundary Correction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alsaidi%20M.%20Altaher">Alsaidi M.

In the presence of outliers this non parametric estimator can not suppress the outliers involved. This study proposes a new two-stage combined method based on the use of the median filter as primary step before applying wavelet thresholding. After suppressing the outliers in a signal through the median filter, the classical wavelet thresholding is then applied for removing the remaining noise. We use automatic boundary corrections; using a low order polynomial model or local polynomial model as a more realistic rule to correct the bias at the boundary region; instead of using the classical assumptions such periodic or symmetric. A simulation experiment has been conducted to evaluate the numerical performance of the proposed method. Results show strong evidences that the proposed method is extremely effective in terms of correcting the boundary bias and eliminating outlier’s sensitivity. <p
