The majority of damage is due to breach in the building envelope such as broken roof, window, and door. In this paper, wind fragility of window glass in residential apartment was determined to compare the difference between two window configuration models. Monte Carlo Simulation method had been used to derive damage data and analytical fragilities were constructed. Fragility of window system showed that window located in leeward wall had higher probability of failure, especially those close to the edge of structure. Between the two window models, Model 2 had higher probability of failure, this was due to the number of panel in this configuration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20fragility" title="wind fragility">wind fragility</a>, <a href="https://publications.waset.org/abstracts/search?q=glass%20window" title=" glass window"> glass window</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20rise%20building" title=" high rise building"> high rise building</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20disaster" title=" wind disaster"> wind disaster</a> </p> <a href="https://publications.waset.org/abstracts/61409/wind-fragility-of-window-glass-in-10-story-apartment-with-two-different-window-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61409.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">256</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">1014</span> Comparison of Wind Fragility for Window System in the Simplified 10 and 15-Story Building Considering Exposure Category </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Viriyavudh%20Sim">Viriyavudh Sim</a>, <a href="https://publications.waset.org/abstracts/search?q=WooYoung%20Jung"> WooYoung Jung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Window system in high rise building is occasionally subjected to an excessive wind intensity, particularly during typhoon. The failure of window system did not affect overall safety of structural performance; however, it could endanger the safety of the residents. In this paper, comparison of fragility curves for window system of two residential buildings was studied. The probability of failure for individual window was determined with Monte Carlo Simulation method. Then, lognormal cumulative distribution function was used to represent the fragility. The results showed that windows located on the edge of leeward wall were more susceptible to wind load and the probability of failure for each window panel increased at higher floors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20fragility" title="wind fragility">wind fragility</a>, <a href="https://publications.waset.org/abstracts/search?q=window%20system" title=" window system"> window system</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20rise%20building" title=" high rise building"> high rise building</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20disaster" title=" wind disaster"> wind disaster</a> </p> <a href="https://publications.waset.org/abstracts/61408/comparison-of-wind-fragility-for-window-system-in-the-simplified-10-and-15-story-building-considering-exposure-category" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61408.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">314</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">1013</span> Effect of Orientation of the Wall Window on Energy Saving under Clear Sky Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Madhu%20Sudan">Madhu Sudan</a>, <a href="https://publications.waset.org/abstracts/search?q=G.%20N.%20Tiwari"> G.

The building has been designed incorporating all passive concepts for thermal comfort as well daylighting concepts to maximize the use of natural daylighting for the occupants in the day to day activities. The annual average DIR and the energy saving has been estimated by using the DIR model for wall window with different orientations under clear sky condition. It has been found that for south oriented window the energy saving per square meter is more compared to the other orientations due to the higher level of solar insolation for the south window in northern hemisphere whereas energy saving potential is minimum for north oriented wall window. The energy saving potential was 26%, 81% and 51% higher for east, south and west oriented window in comparison to north oriented window. The average annual DIR has same trends of variation as the annual energy saving and it is maximum for south oriented window and minimum for north oriented window. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clear%20sky" title="clear sky">clear sky</a>, <a href="https://publications.waset.org/abstracts/search?q=daylight%20factor" title=" daylight factor"> daylight factor</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20saving" title=" energy saving"> energy saving</a>, <a href="https://publications.waset.org/abstracts/search?q=wall%20window" title=" wall window"> wall window</a> </p> <a href="https://publications.waset.org/abstracts/36764/effect-of-orientation-of-the-wall-window-on-energy-saving-under-clear-sky-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36764.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">407</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">1012</span> The Effect of Window Position and Ceiling Height on Cooling Load in Architectural Studio</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyedehzahra%20Mirrahimi">Seyedehzahra Mirrahimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates the effect of variations in window and ceiling heights on cooling inside an architectural training studio with a full-width window. For architectural training, students use the studio more often than they use ordinary classrooms. Therefore, studio dimensions and size, and the window position, directly influence the cooling load. Energy for cooling is one of the most expensive costs in the studio because of the high activity levels of students during the warm season. The methodology of analysis involves measuring energy changes in the Energy Plus <EP> software in Kish Island. It was proved that the cooling energy in an architecture studio can be increased by changing window levels and ceiling heights to add a range of cooling energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cooling%20energy" title="cooling energy">cooling energy</a>, <a href="https://publications.waset.org/abstracts/search?q=Energy%20Plus" title=" Energy Plus"> Energy Plus</a>, <a href="https://publications.waset.org/abstracts/search?q=studio%20classroom" title=" studio classroom"> studio classroom</a>, <a href="https://publications.waset.org/abstracts/search?q=window%20position" title=" window position"> window position</a> </p> <a href="https://publications.waset.org/abstracts/116834/the-effect-of-window-position-and-ceiling-height-on-cooling-load-in-architectural-studio" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116834.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">290</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">1011</span> Development of a One-Window Services Model for Accessing Cancer Immunotherapies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rizwan%20Arshad">Rizwan Arshad</a>, <a href="https://publications.waset.org/abstracts/search?q=Alessio%20Panza"> Alessio Panza</a>, <a href="https://publications.waset.org/abstracts/search?q=Nimra%20Inayat"> Nimra Inayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Syeda%20Mariam%20Batool%20Kazmi"> Syeda Mariam Batool Kazmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shawana%20Azmat"> Shawana Azmat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The rapidly expanding use of immunotherapy for a wide range of cancers from late to early stages has, predictably, been accompanied by evidence of inequities in access to these highly effective but costly treatments.

Because of the problems in the window settings used to evaluate brain CT images, they are very poor in the early stage infarction detection. This paper presents an automatic estimation method for the window settings of the CT images for proper contrast of the hyper infarction present in the brain. In the proposed work the window width is estimated automatically for each slice and the window centre is changed to a new value of 31HU, which is the average of the HU values of the grey matter and white matter in the brain. The automatic window width estimation is based on the average of median of statistical central moments. Thus with the new suggested window centre and estimated window width, the hyper infarction or post-stroke regions in CT brain images are properly detected. The proposed approach assists the radiologists in CT evaluation for early quantitative signs of delayed stroke, which leads to severe hemorrhage in the future can be prevented by providing timely medication to the patients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computed%20tomography%20%28CT%29" title="computed tomography (CT)">computed tomography (CT)</a>, <a href="https://publications.waset.org/abstracts/search?q=hyper%20infarction%20or%20post%20stroke%20region" title=" hyper infarction or post stroke region"> hyper infarction or post stroke region</a>, <a href="https://publications.waset.org/abstracts/search?q=Hounsefield%20Unit%20%28HU%29" title=" Hounsefield Unit (HU)"> Hounsefield Unit (HU)</a>, <a href="https://publications.waset.org/abstracts/search?q=window%20centre%20%28WC%29" title=" window centre (WC)"> window centre (WC)</a>, <a href="https://publications.waset.org/abstracts/search?q=window%20width%20%28WW%29" title=" window width (WW)"> window width (WW)</a> </p> <a href="https://publications.waset.org/abstracts/75360/automatic-post-stroke-detection-from-computed-tomography-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75360.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">203</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">1009</span> Modeling of Silicon Window Layers for Solar Cells Based SIGE</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meriem%20Boukais">Meriem Boukais</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20Dennai"> B.

This study aims to investigate the relationship between window display design elements and value perceptions of local products between two different cultures. The research methodology is based on survey research. Several window displays in favorite of tourist spots were selected as a unit of study. Also, 100 tourists (56 Thai tourists and 44 foreign tourists) were asked to complete a questionnaire. T-Tests were used to analyze the comparison. Then, the results were compared to Thai and foreign tourists. Finally, the results find that Thai and foreign tourists have different perception towards three design elements that are size of the window, props and colour lighting. The differences of their perceptions signify the different cultural values they adhere to. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross-culture" title="cross-culture">cross-culture</a>, <a href="https://publications.waset.org/abstracts/search?q=window%20display" title=" window display"> window display</a>, <a href="https://publications.waset.org/abstracts/search?q=Thai%20craft%20product" title=" Thai craft product"> Thai craft product</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20perception" title=" environmental perception"> environmental perception</a> </p> <a href="https://publications.waset.org/abstracts/45454/window-display-design-of-thai-craft-product-affecting-perceptions-of-thai-and-foreign-tourists" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45454.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">277</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">1006</span> A Model of a Non-expanding Universe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yongbai%20Yin">Yongbai Yin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We propose a non-expanding model of the universe based on the non-changing fine-structure constant and Einstein’s space-time relativity theory. This model consistently explains the Redshift, the ‘expanding’ and the age of the universe without introducing the singularity and inflationary issues that occurred in the ‘Big Bang’ model. It also offers an interpretation of the unexpected ‘accelerated expanding’ universe and the origin of the mystery of ‘Dark matter’. It predicts that the universe began with a ‘cold and peaceful’ rather than ‘extremely hot’ stage which is used to explain consistently the microwave background radiation. It predicts mathematically that galaxies could end in blackholes because blackholes should have the same environmental conditions as those at the beginning of the universe in this model, paving the way to offer a model of the cyclic universes without violating the first law of thermodynamics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20bang" title="big bang">big bang</a>, <a href="https://publications.waset.org/abstracts/search?q=accelerated%20expanding%20universe" title=" accelerated expanding universe"> accelerated expanding universe</a>, <a href="https://publications.waset.org/abstracts/search?q=dark%20matters" title=" dark matters"> dark matters</a>, <a href="https://publications.waset.org/abstracts/search?q=blackholes" title=" blackholes"> blackholes</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20background%20radiation" title=" microwave background radiation"> microwave background radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=universe%20modelling" title=" universe modelling"> universe modelling</a> </p> <a href="https://publications.waset.org/abstracts/194471/a-model-of-a-non-expanding-universe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194471.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">10</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">1005</span> Implementing Two Rotatable Circular Polarized Glass Made Window to Reduce the Amount of Electricity Usage by Air Condition System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imtiaz%20Sarwar">Imtiaz Sarwar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Air conditioning in homes may account for one-third of the electricity during period in summer when most of the energy is required in large cities. It is not consuming only electricity but also has a serious impact on environment including greenhouse effect. Circular polarizer filter can be used to selectively absorb or pass clockwise or counter-clock wise circularly polarized light. My research is about putting two circular polarized glasses parallel to each other and make a circular window with it. When we will place two circular polarized glasses exactly same way (0 degree to each other) then nothing will be noticed rather it will work as a regular window through which all light and heat can pass on. While we will keep rotating one of the circular polarized glasses, the angle between the glasses will keep increasing and the window will keep blocking more and more lights. It will completely block all the lights and a portion of related heat when one of the windows will reach 90 degree to another. On the other hand, we can just open the window when fresh air is necessary. It will reduce the necessity of using Air condition too much or consumer will use electric fan rather than air conditioning system. Thus, we can save a significant amount of electricity and we can go green. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=circular%20polarizer" title="circular polarizer">circular polarizer</a>, <a href="https://publications.waset.org/abstracts/search?q=window" title=" window"> window</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20condition" title=" air condition"> air condition</a>, <a href="https://publications.waset.org/abstracts/search?q=light" title=" light"> light</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a> </p> <a href="https://publications.waset.org/abstracts/22141/implementing-two-rotatable-circular-polarized-glass-made-window-to-reduce-the-amount-of-electricity-usage-by-air-condition-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22141.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">607</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">1004</span> Life Cycle Assessment as a Decision Making for Window Performance Comparison in Green Building Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghada%20Elshafei">Ghada Elshafei</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelazim%20Negm"> Abdelazim Negm </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Life cycle assessment is a technique to assess the environmental aspects and potential impacts associated with a product, process, or service, by compiling an inventory of relevant energy and material inputs and environmental releases; evaluating the potential environmental impacts associated with identified inputs and releases; and interpreting the results to help you make a more informed decision. In this paper, the life cycle assessment of aluminum and beech wood as two commonly used materials in Egypt for window frames are heading, highlighting their benefits and weaknesses. Window frames of the two materials have been assessed on the basis of their production, energy consumption and environmental impacts. It has been found that the climate change of the windows made of aluminum and beech wood window, for a reference window (1.2m × 1.2m), are 81.7 mPt and - 52.5 mPt impacts respectively. Among the most important results are: fossil fuel consumption, potential contributions to the green building effect and quantities of solid waste tend to be minor for wood products compared to aluminum products; incineration of wood products can cause higher impacts of acidification and eutrophication than aluminum, whereas thermal energy can be recovered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminum%20window" title="aluminum window">aluminum window</a>, <a href="https://publications.waset.org/abstracts/search?q=beech%20wood%20window" title=" beech wood window"> beech wood window</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20building" title=" green building"> green building</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assessment" title=" life cycle assessment"> life cycle assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20analysis" title=" life cycle analysis"> life cycle analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=SimaPro%20software" title=" SimaPro software"> SimaPro software</a>, <a href="https://publications.waset.org/abstracts/search?q=window%20frame" title=" window frame"> window frame</a> </p> <a href="https://publications.waset.org/abstracts/34211/life-cycle-assessment-as-a-decision-making-for-window-performance-comparison-in-green-building-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34211.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">450</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">1003</span> Forecasting Equity Premium Out-of-Sample with Sophisticated Regression Training Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jonathan%20Iworiso">Jonathan Iworiso</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Forecasting the equity premium out-of-sample is a major concern to researchers in finance and emerging markets. The quest for a superior model that can forecast the equity premium with significant economic gains has resulted in several controversies on the choice of variables and suitable techniques among scholars. This research focuses mainly on the application of Regression Training (RT) techniques to forecast monthly equity premium out-of-sample recursively with an expanding window method. A broad category of sophisticated regression models involving model complexity was employed. The RT models include Ridge, Forward-Backward (FOBA) Ridge, Least Absolute Shrinkage and Selection Operator (LASSO), Relaxed LASSO, Elastic Net, and Least Angle Regression were trained and used to forecast the equity premium out-of-sample. In this study, the empirical investigation of the RT models demonstrates significant evidence of equity premium predictability both statistically and economically relative to the benchmark historical average, delivering significant utility gains. They seek to provide meaningful economic information on mean-variance portfolio investment for investors who are timing the market to earn future gains at minimal risk. Thus, the forecasting models appeared to guarantee an investor in a market setting who optimally reallocates a monthly portfolio between equities and risk-free treasury bills using equity premium forecasts at minimal risk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=regression%20training" title="regression training">regression training</a>, <a href="https://publications.waset.org/abstracts/search?q=out-of-sample%20forecasts" title=" out-of-sample forecasts"> out-of-sample forecasts</a>, <a href="https://publications.waset.org/abstracts/search?q=expanding%20window" title=" expanding window"> expanding window</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20predictability" title=" statistical predictability"> statistical predictability</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20significance" title=" economic significance"> economic significance</a>, <a href="https://publications.waset.org/abstracts/search?q=utility%20gains" title=" utility gains"> utility gains</a> </p> <a href="https://publications.waset.org/abstracts/154547/forecasting-equity-premium-out-of-sample-with-sophisticated-regression-training-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154547.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">107</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1002</span> Analysis of Formation Methods of Range Profiles for an X-Band Coastal Surveillance Radar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Van%20Loi">Nguyen Van Loi</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Thanh%20Son"> Le Thanh Son</a>, <a href="https://publications.waset.org/abstracts/search?q=Tran%20Trung%20Kien"> Tran Trung Kien</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper deals with the problem of the formation of range profiles (RPs) for an X-band coastal surveillance radar.

The test results show that although the original window-based method achieves a better performance than the difference operator method, it has three main drawbacks that are the use of 3 or 4 peaks of an RP for creating the windows, the extension of the window size using the power sum of three adjacent cells in the left and the right sides of the windows and the same threshold applied for all types of vessels to finish the formation process of RPs. These drawbacks lead to inaccurate RPs due to the low signal-to-clutter ratio.

The challenge therefore, is to develop means of utilizing both direct and diffuse natural light in buildings while maintaining and improving occupant's visual comfort, particularly at greater distances from the windows throwing daylight. The geometrical features of windows in a building have significant effect in providing daylight. The main goal of this research is to develop an innovative window geometry, which will effectively provide the daylight component adequately together with internal reflected component(IRC) and also the external reflected component(ERC), if any. This involves exploration of a light redirecting system using fractal geometry for windows, in order to penetrate and distribute daylight more uniformly to greater depths, minimizing heat gain and glare, and also to reduce building energy use substantially. Of late the creation of fractal geometrical window and the occurrence of daylight illuminance due to such windows is becoming an interesting study. The amount of daylight can change significantly based on the window geometry and sky conditions. This leads to the (i) exploration of various fractal patterns suitable for window designs, and (ii) quantification of the effect of chosen fractal window based on the relationship between the fractal pattern, size, orientation and glazing properties for optimizing daylighting. There are a lot of natural lighting applications able to predict the behaviour of a light in a room through a traditional opening - a regular window. The conventional prediction methodology involves the evaluation of the daylight factor, the internal reflected component and the external reflected component. Having evaluated the daylight illuminance level for a conventional window, the technical performance of a fractal window for an optimal daylighting is to be studied and compared with that of a regular window. The methodologies involved are highlighted in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=daylighting" title="daylighting">daylighting</a>, <a href="https://publications.waset.org/abstracts/search?q=fractal%20geometry" title=" fractal geometry"> fractal geometry</a>, <a href="https://publications.waset.org/abstracts/search?q=fractal%20window" title=" fractal window"> fractal window</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/64228/optimizing-the-window-geometry-using-fractals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64228.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">301</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">1000</span> Efficient Frequent Itemset Mining Methods over Real-Time Spatial Big Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamdi%20Sana">Hamdi Sana</a>, <a href="https://publications.waset.org/abstracts/search?q=Emna%20Bouazizi"> Emna Bouazizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sami%20Faiz"> Sami Faiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, there is a huge increase in the use of spatio-temporal applications where data and queries are continuously moving. As a result, the need to process real-time spatio-temporal data seems clear and real-time stream data management becomes a hot topic. Sliding window model and frequent itemset mining over dynamic data are the most important problems in the context of data mining. Thus, sliding window model for frequent itemset mining is a widely used model for data stream mining due to its emphasis on recent data and its bounded memory requirement. These methods use the traditional transaction-based sliding window model where the window size is based on a fixed number of transactions. Actually, this model supposes that all transactions have a constant rate which is not suited for real-time applications. And the use of this model in such applications endangers their performance. Based on these observations, this paper relaxes the notion of window size and proposes the use of a timestamp-based sliding window model. In our proposed frequent itemset mining algorithm, support conditions are used to differentiate frequents and infrequent patterns. Thereafter, a tree is developed to incrementally maintain the essential information. We evaluate our contribution. The preliminary results are quite promising. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=real-time%20spatial%20big%20data" title="real-time spatial big data">real-time spatial big data</a>, <a href="https://publications.waset.org/abstracts/search?q=frequent%20itemset" title=" frequent itemset"> frequent itemset</a>, <a href="https://publications.waset.org/abstracts/search?q=transaction-based%20sliding%20window%20model" title=" transaction-based sliding window model"> transaction-based sliding window model</a>, <a href="https://publications.waset.org/abstracts/search?q=timestamp-based%20sliding%20window%20model" title=" timestamp-based sliding window model"> timestamp-based sliding window model</a>, <a href="https://publications.waset.org/abstracts/search?q=weighted%20frequent%20patterns" title=" weighted frequent patterns"> weighted frequent patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=tree" title=" tree"> tree</a>, <a href="https://publications.waset.org/abstracts/search?q=stream%20query" title=" stream query"> stream query</a> </p> <a href="https://publications.waset.org/abstracts/102447/efficient-frequent-itemset-mining-methods-over-real-time-spatial-big-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102447.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">161</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">999</span> A Study of New Window Typology for Palestinian Residential Building for More Sustainable Building</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nisreen%20Ardda">Nisreen Ardda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fenestrations are one of the main building envelope elements that play an important role in home social-ecological l factors. They play a vital role in providing natural lighting and ventilation, visual, thermal, and acoustical comfort, and also provide weather-tightness, privacy, a feeling of openness. In most home buildings, fenestrations are controlled manually by the occupants, which significantly impacts occupants' comfort and energy use. Culture plays a central role in the Palestinians window operation behavior. Improved windows design that provides the desired privacy while maintaining the appropriate function of fenestration (natural lighting, thermal comfort, and visual openness) is becoming a necessity. Therefore, this paper proposes a window typology to achieve the social and environmental factors in residential buildings in the West Bank. The window typology and reference building were designed in Rivet 2021, and natural ventilation was carried out in Design Builder 4.3.0.039. The results showed that the proposed typology provides the desired privacy and the feeling of openness without compromising natural ventilation as the existing window did. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=window%20design" title="window design">window design</a>, <a href="https://publications.waset.org/abstracts/search?q=passive%20design" title=" passive design"> passive design</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20built%20environment" title=" sustainable built environment"> sustainable built environment</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20material" title=" building material"> building material</a> </p> <a href="https://publications.waset.org/abstracts/141764/a-study-of-new-window-typology-for-palestinian-residential-building-for-more-sustainable-building" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141764.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">186</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">998</span> Nano Sol Based Solar Responsive Smart Window for Aircraft</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20A.%20D.%20D.%20Kuruppu">K.

Further, this surface has the potential of harvesting energy from Solar. The transparent inorganic nano sol solution was prepared. The obtained sol solution was characterized using X-ray diffraction, Particle size analyzer and FT-IR. The existing nano material which shows the similar characteristics was also used to compare the efficiencies with the newly prepared nano sol. Nano sol solution was coated on cleaned four aircraft window pieces separately using a spin coater machine. The existing nano material was dissolved and prepared a solution having the similar concentration as nano sol solution. Pre-cleaned four aircraft window pieces were coated with this solution and the rest cleaned four aircraft window pieces were considered as control samples. The control samples were uncoated from anything. All the window pieces were allowed to dry at room temperature. All the twelve aircraft window pieces were uniform in all the factors other than the type of coating. The surface morphologies of the samples were analyzed using SEM. The photocatalytic degradation of VOC was determined after incorporating gas of Toluene to each sample followed by the analysis done by UV-VIS spectroscopy. The self- cleaning capabilities were analyzed after adding of several types of stains on the window pieces. The self-cleaning property of each sample was analyzed using UV-VIS spectroscopy. The highest photocatalytic degradation of Volatile Organic compound and the highest photocatalytic degradation of stains were obtained for the samples which were coated by the nano sol solution. Therefore, the experimental results clearly show that there is a potential of using this nano sol in aircraft window pieces which favors the self-cleaning property as well as efficient photocatalytic degradation of VOC gases. This will ensure safer environment inside aircraft cabins. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aircraft" title="aircraft">aircraft</a>, <a href="https://publications.waset.org/abstracts/search?q=nano" title=" nano"> nano</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20windows" title=" smart windows"> smart windows</a>, <a href="https://publications.waset.org/abstracts/search?q=solar" title=" solar"> solar</a> </p> <a href="https://publications.waset.org/abstracts/82069/nano-sol-based-solar-responsive-smart-window-for-aircraft" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82069.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">256</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">997</span> Variable vs. Fixed Window Width Code Correlation Reference Waveform Receivers for Multipath Mitigation in Global Navigation Satellite Systems with Binary Offset Carrier and Multiplexed Binary Offset Carrier Signals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fahad%20Alhussein">Fahad Alhussein</a>, <a href="https://publications.waset.org/abstracts/search?q=Huaping%20Liu"> Huaping Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper compares the multipath mitigation performance of code correlation reference waveform receivers with variable and fixed window width, for binary offset carrier and multiplexed binary offset carrier signals typically used in global navigation satellite systems. In the variable window width method, such width is iteratively reduced until the distortion on the discriminator with multipath is eliminated. This distortion is measured as the Euclidean distance between the actual discriminator (obtained with the incoming signal), and the local discriminator (generated with a local copy of the signal). The variable window width have shown better performance compared to the fixed window width. In particular, the former yields zero error for all delays for the BOC and MBOC signals considered, while the latter gives rather large nonzero errors for small delays in all cases. Due to its computational simplicity, the variable window width method is perfectly suitable for implementation in low-cost receivers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=correlation%20reference%20waveform%20receivers" title="correlation reference waveform receivers">correlation reference waveform receivers</a>, <a href="https://publications.waset.org/abstracts/search?q=binary%20offset%20carrier" title=" binary offset carrier"> binary offset carrier</a>, <a href="https://publications.waset.org/abstracts/search?q=multiplexed%20binary%20offset%20carrier" title=" multiplexed binary offset carrier"> multiplexed binary offset carrier</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20navigation%20satellite%20systems" title=" global navigation satellite systems"> global navigation satellite systems</a> </p> <a href="https://publications.waset.org/abstracts/116944/variable-vs-fixed-window-width-code-correlation-reference-waveform-receivers-for-multipath-mitigation-in-global-navigation-satellite-systems-with-binary-offset-carrier-and-multiplexed-binary-offset-carrier-signals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116944.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">996</span> Classification of EEG Signals Based on Dynamic Connectivity Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zoran%20%C5%A0verko">Zoran Šverko</a>, <a href="https://publications.waset.org/abstracts/search?q=Sa%C5%A1a%20Vlahini%C4%87"> Saša Vlahinić</a>, <a href="https://publications.waset.org/abstracts/search?q=Nino%20Stojkovi%C4%87"> Nino Stojković</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivan%20Markovinovi%C4%87"> Ivan Markovinović</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, the classification of target letters is performed using data from the EEG P300 Speller paradigm.

The RICI-imCPCC method overcomes the shortcomings of currently used dynamical connectivity analysis methods, such as the low reliability and low temporal precision for short connectivity intervals encountered in constant sliding window analysis with wide window size and the high susceptibility to noise encountered in constant sliding window analysis with narrow window size. This method overcomes these shortcomings by dynamically adjusting the window size using the RICI rule. This method extracts information about brain connections for each time sample. Seventy percent of the extracted brain connectivity information is used for training and thirty percent for validation. Classification of the target word is also done and based on the same analysis method. As far as we know, through this research, we have shown for the first time that dynamic connectivity can be used as a parameter for classifying EEG signals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20connectivity%20analysis" title="dynamic connectivity analysis">dynamic connectivity analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=EEG" title=" EEG"> EEG</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20networks" title=" neural networks"> neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=Pearson%20correlation%20coefficients" title=" Pearson correlation coefficients"> Pearson correlation coefficients</a> </p> <a href="https://publications.waset.org/abstracts/159091/classification-of-eeg-signals-based-on-dynamic-connectivity-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159091.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">214</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">995</span> Grammatical and Lexical Explorations on ‘Outer Circle’ Englishes and ‘Expanding Circle’ Englishes: A Corpus-Based Comparative Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Orlyn%20Joyce%20D.%20Esquivel">Orlyn Joyce D.

The selected outer circle Englishes include those of Bangladesh, Malaysia, the Philippines, India, and Singapore; and the selected expanding circle Englishes are those of China, Indonesia, Japan, Korea, and Thailand. The researcher built ten corpora (five research papers for each corpus) to represent each variety of Englishes. The corpora were examined under grammatical and lexical features using Modified English TreeTagger in Sketch Engine. Results revealed the distinct grammatical and lexical features through the table and textual analyses, illustrated from the most to least dominant linguistic elements. In addition, comparative analyses were done to distinguish the features of each of the selected Englishes. The Language Change Theory was used as a basis in the discussion. Hence, the findings suggest that the ‘outer circle’ Englishes and ‘expanding circle’ Englishes will continue to drift from International English. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=applied%20linguistics" title="applied linguistics">applied linguistics</a>, <a href="https://publications.waset.org/abstracts/search?q=English%20as%20a%20global%20language" title=" English as a global language"> English as a global language</a>, <a href="https://publications.waset.org/abstracts/search?q=expanding%20circle%20Englishes" title=" expanding circle Englishes"> expanding circle Englishes</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20Englishes" title=" global Englishes"> global Englishes</a>, <a href="https://publications.waset.org/abstracts/search?q=outer%20circle%20Englishes" title=" outer circle Englishes"> outer circle Englishes</a> </p> <a href="https://publications.waset.org/abstracts/110861/grammatical-and-lexical-explorations-on-outer-circle-englishes-and-expanding-circle-englishes-a-corpus-based-comparative-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110861.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">161</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">994</span> An Improved Dynamic Window Approach with Environment Awareness for Local Obstacle Avoidance of Mobile Robots</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Baoshan%20Wei">Baoshan Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuai%20Han"> Shuai Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Xing%20Zhang"> Xing Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Local obstacle avoidance is critical for mobile robot navigation. It is a challenging task to ensure path optimality and safety in cluttered environments. We proposed an Environment Aware Dynamic Window Approach in this paper to cope with the issue. The method integrates environment characterization into Dynamic Window Approach (DWA). Two strategies are proposed in order to achieve the integration. The local goal strategy guides the robot to move through openings before approaching the final goal, which solves the local minima problem in DWA. The adaptive control strategy endows the robot to adjust its state according to the environment, which addresses path safety compared with DWA. Besides, the evaluation shows that the path generated from the proposed algorithm is safer and smoother compared with state-of-the-art algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptive%20control" title="adaptive control">adaptive control</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20window%20approach" title=" dynamic window approach"> dynamic window approach</a>, <a href="https://publications.waset.org/abstracts/search?q=environment%20aware" title=" environment aware"> environment aware</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20obstacle%20avoidance" title=" local obstacle avoidance"> local obstacle avoidance</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20robots" title=" mobile robots"> mobile robots</a> </p> <a href="https://publications.waset.org/abstracts/102425/an-improved-dynamic-window-approach-with-environment-awareness-for-local-obstacle-avoidance-of-mobile-robots" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102425.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">159</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">993</span> An Enhanced Hybrid Backoff Technique for Minimizing the Occurrence of Collision in Mobile Ad Hoc Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Sabiyath%20Fatima">N.

The existing backoff models do not exactly forecast the performance of the wireless network. Also, the existing models experience elevated packet collisions. Every time a collision happens, the station’s contention window (CW) is doubled till it arrives at the utmost value. The main objective of this paper is to diminish collision by means of contention window Multiplicative Increase Decrease Backoff (CWMIDB) scheme. The intention of rising CW is to shrink the collision possibility by distributing the traffic into an outsized point in time. Within wireless Ad hoc networks, the CWMIDB algorithm dynamically controls the contention window of the nodes experiencing collisions. During packet communication, the backoff counter is evenly selected from the given choice of [0, CW-1]. At this point, CW is recognized as contention window and its significance lies on the amount of unsuccessful transmission that had happened for the packet. On the initial transmission endeavour, CW is put to least amount value (C min), if transmission effort fails, subsequently the value gets doubled, and once more the value is set to least amount on victorious broadcast. CWMIDB is simulated inside NS2 environment and its performance is compared with Binary Exponential Backoff Algorithm. The simulation results show improvement in transmission probability compared to that of the existing backoff algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=backoff" title="backoff">backoff</a>, <a href="https://publications.waset.org/abstracts/search?q=contention%20window" title=" contention window"> contention window</a>, <a href="https://publications.waset.org/abstracts/search?q=CWMIDB" title=" CWMIDB"> CWMIDB</a>, <a href="https://publications.waset.org/abstracts/search?q=MANET" title=" MANET"> MANET</a> </p> <a href="https://publications.waset.org/abstracts/77080/an-enhanced-hybrid-backoff-technique-for-minimizing-the-occurrence-of-collision-in-mobile-ad-hoc-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77080.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">277</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">992</span> The Impact of the Windows Opening on the Design of Buildings in Islamic Architecture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salma%20I.%20Dwidar">Salma I.

It is the eye that sees from, the lunges of the construction, and the ear to hear. The success of the building, as well as the comfort of the uses, depends mainly on this relationship. Usually, windows are affected by human factors like religious, social, political and economic factors as well as environmental factors like climatic, aesthetic and functional factors. In Islamic architecture, the windows were one of the most important elements of physiological and psychological comfort to the users of the buildings. Windows considered one of the main parameters in designing internal and external facade, where the window openings occupied a big part of the formation of the external facade of the buildings. This paper discusses the importance of the window openings and its relationship to residential buildings in the Islamic architecture. It addresses the rules that have been followed in the design of windows in Islamic architecture to achieve privacy and thermal comfort while there are no technological elements within the dwellings. Also, it demonstrates the effects of windows on the building form and identity and how it gives a distinctive fingerprint of the architecture buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=window%20openings" title="window openings">window openings</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20comfort" title=" thermal comfort"> thermal comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=residential%20buildings" title=" residential buildings"> residential buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20Islamic%20architecture" title=" the Islamic architecture"> the Islamic architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20considerations" title=" human considerations"> human considerations</a> </p> <a href="https://publications.waset.org/abstracts/100212/the-impact-of-the-windows-opening-on-the-design-of-buildings-in-islamic-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100212.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">221</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">991</span> Investigating the Effect of Adding the Window Layer and the Back Surface Field Layer of InₓGa₍₁₋ₓ₎P Material to GaAs Single Junction Solar Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Taghinia">Ahmad Taghinia</a>, <a href="https://publications.waset.org/abstracts/search?q=Negar%20Gholamishaker"> Negar Gholamishaker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> GaAs (gallium arsenide) solar cells have gained significant attention for their use in space applications.

Materials and Methods: By analyzing the high-resolution CT of 160 cases (320 pleural ears) of the temporal bone, the following parameters were measured at the axial window niche level: 1. The distance between the facial nerve and chordae tympani nerve d1; 2. Distance between the facial nerve and circular window niche d2; 3. The relative Angle between the facial nerve and the circular window niche a; 4. Distance between the middle point of the face recess and the circular window niche d3; 5. The relative angle between the middle point of the face recess and the circular window niche b. Factors that might influence the anatomy of the facial recess were recorded, including the patient's sex, age, and anatomical variation (e.g., vestibular duct dilation, mastoid gas type, mothoid sinus advancement, jugular bulbar elevation, etc.), and the correlation between these factors and the measured facial recess parameters was analyzed. Result: The mean value of face-drum distance d1 is (3.92 ± 0.26) mm, the mean value of face-niche distance d2 is (5.95 ± 0.62) mm, the mean value of face-niche Angle a is (94.61 ± 9.04) °, and the mean value of fossa - niche distance d3 is (6.46 ± 0.63) mm. The average fossa-niche Angle b was (113.47 ± 7.83) °. Gender, age, and anterior sigmoid sinus were the three factors affecting the width of the opposite recess d1, the Angle of the opposite nerve relative to the circular window niche a, and the Angle of the facial recess relative to the circular window niche b. Conclusion: High-resolution temporal bone CT before cochlear implantation can show the important anatomical relationship of the facial nerve recess, and the measurement results have clinical reference value for the operation of cochlear implantation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cochlear%20implantation" title="cochlear implantation">cochlear implantation</a>, <a href="https://publications.waset.org/abstracts/search?q=recess%20of%20facial%20nerve" title=" recess of facial nerve"> recess of facial nerve</a>, <a href="https://publications.waset.org/abstracts/search?q=temporal%20bone%20CT" title=" temporal bone CT"> temporal bone CT</a>, <a href="https://publications.waset.org/abstracts/search?q=three-dimensional%20measurement" title=" three-dimensional measurement"> three-dimensional measurement</a> </p> <a href="https://publications.waset.org/abstracts/192591/three-dimensional-measurement-and-analysis-of-facial-nerve-recess" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192591.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">16</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">989</span> Step Height Calibration Using Hamming Window: Band-Pass Filter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dahi%20Ghareab%20Abdelsalam%20Ibrahim">Dahi Ghareab Abdelsalam Ibrahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Calibration of step heights with high accuracy is needed for many applications in the industry. In general, step height consists of three bands: pass band, transition band (roll-off), and stop band. Abdelsalam used a convolution of the transfer functions of both Chebyshev type 2 and elliptic filters with WFF of the Fresnel transform in the frequency domain for producing a steeper roll-off with the removal of ripples in the pass band- and stop-bands. In this paper, we used a new method based on the Hamming window: band-pass filter for calibration of step heights in terms of perfect adjustment of pass-band, roll-off, and stop-band. The method is applied to calibrate a nominal step height of 40 cm. The step height is measured first by asynchronous dual-wavelength phase-shift interferometry. The measured step height is then calibrated by the simulation of the Hamming window: band-pass filter. The spectrum of the simulated band-pass filter is simulated at N = 881 and f0 = 0.24. We can conclude that the proposed method can calibrate any step height by adjusting only two factors which are N and f0. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optical%20metrology" title="optical metrology">optical metrology</a>, <a href="https://publications.waset.org/abstracts/search?q=step%20heights" title=" step heights"> step heights</a>, <a href="https://publications.waset.org/abstracts/search?q=hamming%20window" title=" hamming window"> hamming window</a>, <a href="https://publications.waset.org/abstracts/search?q=band-pass%20filter" title=" band-pass filter"> band-pass filter</a> </p> <a href="https://publications.waset.org/abstracts/168134/step-height-calibration-using-hamming-window-band-pass-filter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168134.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">83</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">988</span> Time Series Forecasting (TSF) Using Various Deep Learning Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jimeng%20Shi">Jimeng Shi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahek%20Jain"> Mahek Jain</a>, <a href="https://publications.waset.org/abstracts/search?q=Giri%20Narasimhan"> Giri Narasimhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Time Series Forecasting (TSF) is used to predict the target variables at a future time point based on the learning from previous time points. To keep the problem tractable, learning methods use data from a fixed-length window in the past as an explicit input. In this paper, we study how the performance of predictive models changes as a function of different look-back window sizes and different amounts of time to predict the future. We also consider the performance of the recent attention-based Transformer models, which have had good success in the image processing and natural language processing domains. In all, we compare four different deep learning methods (RNN, LSTM, GRU, and Transformer) along with a baseline method. The dataset (hourly) we used is the Beijing Air Quality Dataset from the UCI website, which includes a multivariate time series of many factors measured on an hourly basis for a period of 5 years (2010-14). For each model, we also report on the relationship between the performance and the look-back window sizes and the number of predicted time points into the future. Our experiments suggest that Transformer models have the best performance with the lowest Mean Average Errors (MAE = 14.599, 23.273) and Root Mean Square Errors (RSME = 23.573, 38.131) for most of our single-step and multi-steps predictions. The best size for the look-back window to predict 1 hour into the future appears to be one day, while 2 or 4 days perform the best to predict 3 hours into the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20quality%20prediction" title="air quality prediction">air quality prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning%20algorithms" title=" deep learning algorithms"> deep learning algorithms</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20series%20forecasting" title=" time series forecasting"> time series forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=look-back%20window" title=" look-back window"> look-back window</a> </p> <a href="https://publications.waset.org/abstracts/146879/time-series-forecasting-tsf-using-various-deep-learning-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146879.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">154</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">987</span> Multimodality in Storefront Windows: The Impact of Verbo-Visual Design on Consumer Behavior</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Angela%20Bargenda">Angela Bargenda</a>, <a href="https://publications.waset.org/abstracts/search?q=Erhard%20Lick"> Erhard Lick</a>, <a href="https://publications.waset.org/abstracts/search?q=Dhoha%20Trabelsi"> Dhoha Trabelsi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Research in retailing has identified the importance of atmospherics as an essential element in enhancing store image, store patronage intentions, and the overall shopping experience in a retail environment. However, in the area of atmospherics, store window design, which represents an essential component of external store atmospherics, remains a vastly underrepresented phenomenon in extant scholarship. This paper seeks to fill this gap by exploring the relevance of store window design as an atmospheric tool. In particular, empirical evidence of theme-based theatrical store front windows, which put emphasis on the use of verbo-visual design elements, was found in Paris and New York. The purpose of this study was to identify to what extent such multimodal window designs of high-end department stores in metropolitan cities have an impact on store entry decisions and attitudes towards the retailer’s image. As theoretical construct, the linguistic concept of multimodality and Mehrabian’s and Russell’s model in environmental psychology were applied. To answer the research question, two studies were conducted. For Study 1 a case study approach was selected to define three different types of store window designs based on different types of visual-verbal relations. Each of these types of store window design represented a different level of cognitive elaboration required for the decoding process. Study 2 consisted of an on-line survey carried out among more than 300 respondents to examine the influence of these three types of store window design on the consumer behavioral variables mentioned above. The results of this study show that the higher the cognitive elaboration needed to decode the message of the store window, the lower the store entry propensity. In contrast, the higher the cognitive elaboration, the higher the perceived image of the retailer’s image. One important conclusion is that in order to increase consumers’ propensity to enter stores with theme-based theatrical store front windows, retailers need to limit the cognitive elaboration required to decode their verbo-visual window design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consumer%20behavior" title="consumer behavior">consumer behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=multimodality" title=" multimodality"> multimodality</a>, <a href="https://publications.waset.org/abstracts/search?q=store%20atmospherics" title=" store atmospherics"> store atmospherics</a>, <a href="https://publications.waset.org/abstracts/search?q=store%20window%20design" title=" store window design"> store window design</a> </p> <a href="https://publications.waset.org/abstracts/82770/multimodality-in-storefront-windows-the-impact-of-verbo-visual-design-on-consumer-behavior" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82770.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">202</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">986</span> Fill Rate Window as a Criterion for Spares Allocation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Dreyfuss">Michael Dreyfuss</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahel%20Giat"> Yahel Giat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Limited battery range and long recharging times are the greatest obstacles to the successful adoption of electric cars. One of the suggestions to overcome these problems is that carmakers retain ownership of batteries and provide battery swapping service so that customers exchange their depleted batteries for recharged batteries. Motivated by this example, we consider the problem of optimal spares allocation in an exchangeable-item, multi-location repair system. We generalize the standard service measures of fill rate and average waiting time to reflect the fact that customers penalize the service provider only if they have to wait more than a ‘tolerable’ time window. These measures are denoted as the window fill rate and the truncated waiting time, respectively. We find that the truncated waiting time is convex and therefore a greedy algorithm solves the spares allocation problem efficiently. We show that the window fill rate is generally S-shaped and describe an efficient algorithm to find a near-optimal solution and detail a priori and a posteriori upper bounds to the distance from optimum. The theory is complemented with a large scale numerical example demonstrating the spare battery allocation in battery swapping stations. <p class="card-text"><strong>Keywords:</strong> <a
