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">5506</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 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 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">5503</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">5502</span> Efficient DCT Architectures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mr.%20P.%20Suryaprasad">Mr. P.

These are supported to different lengths (4, 8, 16, and 32). DCT blocks are used in the different video coding standards for the image compression. The 2D- DCT calculation is made using the 2D-DCT separability property, such that the whole architecture is divided into two 1D-DCT calculations by using a transpose buffer. Based on the existing 1D-DCT architecture two different types of 2D-DCT architectures, folded and parallel types are implemented. Both of these two structures use the same transpose buffer. Proposed transpose buffer occupies less area and high speed than existing transpose buffer. Hence the area, low power and delay of both the 2D-DCT architectures are reduced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transposition%20buffer" title="transposition buffer">transposition buffer</a>, <a href="https://publications.waset.org/abstracts/search?q=video%20compression" title=" video compression"> video compression</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20cosine%20transform" title=" discrete cosine transform"> discrete cosine transform</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20efficiency%20video%20coding" title=" high efficiency video coding"> high efficiency video coding</a>, <a href="https://publications.waset.org/abstracts/search?q=two%20dimensional%20picture" title=" two dimensional picture"> two dimensional picture</a> </p> <a href="https://publications.waset.org/abstracts/33624/efficient-dct-architectures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33624.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">521</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">5501</span> Automatic Post Stroke Detection from Computed Tomography Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Gopi%20Jinimole">C.

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">5500</span> Energy Absorption Characteristic of a Coupler Rubber Buffer Used in Rail Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhixiang%20Li">Zhixiang Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuguang%20Yao"> Shuguang Yao</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen%20Ma"> Wen Ma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Coupler rubber buffer has been widely applied on the high-speed trains and the main function of the rubber buffer is dissipating the impact energy between vehicles. The rubber buffer consists of two groups of rubbers, which are both pre-compressed and then installed into the frame body. This paper focuses on the energy absorption characteristics of the rubber buffers particularly. Firstly, the quasi-static compression tests were carried out for 1 and 3 pairs of rubber sheets and some energy absorption responses relationship, i.e. Eabn = n×Eab1, Edissn = n×Ediss1, and Ean = Ea1, were obtained. Next, a series of quasi-static tests were performed for 1 pair of rubber sheet to investigate the energy absorption performance with different compression ratio of the rubber buffers. Then the impact tests with five impact velocities were conducted and the coupler knuckle was destroyed when the impact velocity was 10.807 km/h. The impact tests results showed that with the increase of impact velocity, the Eab, Ediss and Ea of rear buffer increased a lot, but the three responses of front buffer had not much increase. Finally, the results of impact tests and quasi-static tests were contrastively analysed and the results showed that with the increase of the stroke, the values of Eab, Ediss, and Ea were all increase. However, the increasing rates of impact tests were all larger than that of quasi-static tests. The maximum value of Ea was 68.76% in impact tests, it was a relatively high value for vehicle coupler buffer. The energy capacity of the rear buffer was determined for dynamic loading, it was 22.98 kJ. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rubber%20buffer" title="rubber buffer">rubber buffer</a>, <a href="https://publications.waset.org/abstracts/search?q=coupler" title=" coupler"> coupler</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20absorption" title=" energy absorption"> energy absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20tests" title=" impact tests"> impact tests</a> </p> <a href="https://publications.waset.org/abstracts/96059/energy-absorption-characteristic-of-a-coupler-rubber-buffer-used-in-rail-vehicles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96059.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">5499</span> Effects of Bacteria on Levels of AFM1 in Phosphate Buffer at Different Level of Energy Source</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20M.%20Elgerbi">Ali M.

With 1.0% glucose lactic acid bacteria and bifidobacteria showed toxin removal ranging from 7.7 to 39.7% whereas with 10.0% glucose the percentage removal was 21.8 to 45.4% at 96 hours of incubation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aflatoxin%20M1" title="aflatoxin M1">aflatoxin M1</a>, <a href="https://publications.waset.org/abstracts/search?q=lactic%20acid%20bacteria" title=" lactic acid bacteria"> lactic acid bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=bifidobacteria" title=" bifidobacteria "> bifidobacteria </a>, <a href="https://publications.waset.org/abstracts/search?q=binding" title=" binding"> binding</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphate%20buffer" title=" phosphate buffer "> phosphate buffer </a> </p> <a href="https://publications.waset.org/abstracts/19875/effects-of-bacteria-on-levels-of-afm1-in-phosphate-buffer-at-different-level-of-energy-source" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19875.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">506</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">5498</span> Unbalanced Mean-Time and Buffer Effects in Lines Suffering Breakdown</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabry%20Shaaban">Sabry Shaaban</a>, <a href="https://publications.waset.org/abstracts/search?q=Tom%20McNamara"> Tom McNamara</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Hudson"> Sarah Hudson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article studies the performance of unpaced serial production lines that are subject to breakdown and are imbalanced in terms of both of their processing time means (MTs) and buffer storage capacities (BCs). Simulation results show that the best pattern in terms of throughput is a balanced line with respect to average buffer level; the best configuration is a monotone decreasing MT order, together with an ascending BC arrangement. Statistical analysis shows that BC, patterns of MT and BC imbalance, line length and degree of imbalance all contribute significantly to performance. Results show that unbalanced lines cope well with unreliability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unreliable%20unpaced%20serial%20lines" title="unreliable unpaced serial lines">unreliable unpaced serial lines</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=unequal%20mean%20operation%20times" title=" unequal mean operation times"> unequal mean operation times</a>, <a href="https://publications.waset.org/abstracts/search?q=uneven%20buffer%20capacities" title=" uneven buffer capacities"> uneven buffer capacities</a>, <a href="https://publications.waset.org/abstracts/search?q=patterns%20of%20imbalance" title=" patterns of imbalance"> patterns of imbalance</a>, <a href="https://publications.waset.org/abstracts/search?q=throughput" title=" throughput"> throughput</a>, <a href="https://publications.waset.org/abstracts/search?q=average%20buffer%20level" title=" average buffer level"> average buffer level</a> </p> <a href="https://publications.waset.org/abstracts/3491/unbalanced-mean-time-and-buffer-effects-in-lines-suffering-breakdown" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3491.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">473</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">5497</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.

Therefore, network suffers with some problems like long message relay time, bottle neck problem which reduces the performance of the network. Many approaches have been proposed to prevent this problem with the help of mobile sink to collect the data from the sensor nodes, but these approaches still suffer from the buffer overflow problem due to limited memory size of sensor nodes. This paper proposes an energy efficient scheme for data gathering which overcomes the buffer overflow problem. The proposed scheme creates virtual grid structure of heterogeneous nodes. Scheme has been designed for sensor nodes having variable sensing rate. Every node finds out its buffer overflow time and on the basis of this cluster heads are elected. A controlled traversing approach is used by the proposed scheme in order to transmit data to sink. The effectiveness of the proposed scheme is verified by simulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buffer%20overflow%20problem" title="buffer overflow problem">buffer overflow problem</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20sink" title=" mobile sink"> mobile sink</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20grid" title=" virtual grid"> virtual grid</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20networks" title=" wireless sensor networks"> wireless sensor networks</a> </p> <a href="https://publications.waset.org/abstracts/11672/a-virtual-grid-based-energy-efficient-data-gathering-scheme-for-heterogeneous-sensor-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11672.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">391</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">5494</span> Riparian Buffer Strips’ Capability of E. coli Removal in New York Streams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Helen%20Sanders">Helen Sanders</a>, <a href="https://publications.waset.org/abstracts/search?q=Joshua%20Cousins"> Joshua Cousins</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study is to ascertain whether riparian buffer strips could be used to reduce Escherichia Coli (E. coli) runoff into streams in Central New York. Mainstream methods currently utilized to reduce E. coli runoff include fencing and staggered fertilizing plans for agriculture. These methods still do not significantly limit E. coli and thus, pose a serious health risk to individuals who swim in contaminated waters or consume contaminated produce. One additional method still in research development involves the planting of vegetated riparian buffers along waterways. Currently, riparian buffer strips are primarily used for filtration of nitrate and phosphate runoff to slow erosion, regulate pH and, improve biodiversity within waterways. For my research, four different stream sites were selected for the study, in which rainwater runoff was collected at both the riparian buffer and the E. coli sourced runoff upstream. Preliminary results indicate that there is an average 70% decrease in E. coli content in streams at the riparian buffer strips compared to upstream runoff. This research could be utilized to include vegetated buffer planting as a method to decrease manure runoff into essential waterways. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Escherichia%20coli" title="Escherichia coli">Escherichia coli</a>, <a href="https://publications.waset.org/abstracts/search?q=riparian%20buffer%20strips" title=" riparian buffer strips"> riparian buffer strips</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetated%20riparian%20buffers" title=" vegetated riparian buffers"> vegetated riparian buffers</a>, <a href="https://publications.waset.org/abstracts/search?q=runoff" title=" runoff"> runoff</a>, <a href="https://publications.waset.org/abstracts/search?q=filtration" title=" filtration"> filtration</a> </p> <a href="https://publications.waset.org/abstracts/142236/riparian-buffer-strips-capability-of-e-coli-removal-in-new-york-streams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142236.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">179</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">5493</span> Window Display Design of Thai Craft Product Affecting Perceptions of Thai and Foreign Tourists </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kanokwan%20Somoon">Kanokwan Somoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Chumporn%20Moorapun"> Chumporn Moorapun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A product’s perceived value may increase purchase intention.

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.

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 href="https://publications.waset.org/abstracts/search?q=convex-concave%20optimization" title="convex-concave optimization">convex-concave optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=exchangeable%20item" title=" exchangeable item"> exchangeable item</a>, <a href="https://publications.waset.org/abstracts/search?q=M%2FG%2Finfinity" title=" M/G/infinity"> M/G/infinity</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20location" title=" multiple location"> multiple location</a>, <a href="https://publications.waset.org/abstracts/search?q=repair%20system" title=" repair system"> repair system</a>, <a href="https://publications.waset.org/abstracts/search?q=spares%20allocation" title=" spares allocation"> spares allocation</a>, <a href="https://publications.waset.org/abstracts/search?q=window%20fill%20rate" title=" window fill rate"> window fill rate</a> </p> <a href="https://publications.waset.org/abstracts/35185/fill-rate-window-as-a-criterion-for-spares-allocation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35185.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">493</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">5491</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">5490</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">5489</span> A New Approach for Improving Accuracy of Multi Label Stream Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kunal%20Shah">Kunal Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Swati%20Patel"> Swati Patel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many real world problems involve data which can be considered as multi-label data streams. Efficient methods exist for multi-label classification in non streaming scenarios. However, learning in evolving streaming scenarios is more challenging, as the learners must be able to adapt to change using limited time and memory. Classification is used to predict class of unseen instance as accurate as possible. Multi label classification is a variant of single label classification where set of labels associated with single instance. Multi label classification is used by modern applications, such as text classification, functional genomics, image classification, music categorization etc. This paper introduces the task of multi-label classification, methods for multi-label classification and evolution measure for multi-label classification. Also, comparative analysis of multi label classification methods on the basis of theoretical study, and then on the basis of simulation was done on various data sets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=binary%20relevance" title="binary relevance">binary relevance</a>, <a href="https://publications.waset.org/abstracts/search?q=concept%20drift" title=" concept drift"> concept drift</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20stream%20mining" title=" data stream mining"> data stream mining</a>, <a href="https://publications.waset.org/abstracts/search?q=MLSC" title=" MLSC"> MLSC</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20window%20with%20buffer" title=" multiple window with buffer"> multiple window with buffer</a> </p> <a href="https://publications.waset.org/abstracts/33035/a-new-approach-for-improving-accuracy-of-multi-label-stream-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33035.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">584</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">5488</span> Sundarban as a Buffer against Storm Surge Flooding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohiuddin%20Sakib">Mohiuddin Sakib</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatin%20Nihal"> Fatin Nihal</a>, <a href="https://publications.waset.org/abstracts/search?q=Anisul%20Haque"> Anisul Haque</a>, <a href="https://publications.waset.org/abstracts/search?q=Munsur%20Rahman"> Munsur Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mansur%20Ali"> Mansur Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sundarban, the largest mangrove forest in the world, is known to act as a buffer against the cyclone and storm surge. Theoretically, Sundarban absorbs the initial thrust of the wind and acts to ‘resist’ the storm surge flooding. The role of Sundarban was evident during the cyclone Sidr when the Sundarban solely defended the initial thrust of the cyclonic wind and the resulting storm surge inundation. In doing this, Sundarban sacrificed 30% of its plant habitats. Although no scientific study has yet been conducted, it is generally believed that Sundarban will continuously play its role as a buffer against the cyclone when landfall of the cyclone is at or close to the Sundarban. Considering these facts, the present study mainly focused on a scientific insight into the role of Sundarban as a buffer against the present-day cyclone and storm surge and also its probable role on the impacts of future storms of similar nature but with different landfall locations. The Delft 3D dashboard and flow model are applied to compute the resulting inundation due to cyclone induced storm surge. The results show that Sundarban indeed acts as a buffer against the storm surge inundation when cyclone landfall is at or close to Sundarban. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buffer" title="buffer">buffer</a>, <a href="https://publications.waset.org/abstracts/search?q=Mangrove%20forest" title=" Mangrove forest"> Mangrove forest</a>, <a href="https://publications.waset.org/abstracts/search?q=Sidr" title=" Sidr"> Sidr</a>, <a href="https://publications.waset.org/abstracts/search?q=landfall" title=" landfall"> landfall</a>, <a href="https://publications.waset.org/abstracts/search?q=roughness" title=" roughness"> roughness</a> </p> <a href="https://publications.waset.org/abstracts/37352/sundarban-as-a-buffer-against-storm-surge-flooding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37352.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">394</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">5487</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. Two popular methods, the difference operator method, and the window-based method, are reviewed and analyzed via two tests with different datasets. 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. Therefore, some suggestions are proposed to improve the original window-based method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=range%20profile" title="range profile">range profile</a>, <a href="https://publications.waset.org/abstracts/search?q=difference%20operator%20method" title=" difference operator method"> difference operator method</a>, <a href="https://publications.waset.org/abstracts/search?q=window-based%20method" title=" window-based method"> window-based method</a>, <a href="https://publications.waset.org/abstracts/search?q=automatic%20target%20recognition" title=" automatic target recognition"> automatic target recognition</a> </p> <a href="https://publications.waset.org/abstracts/134878/analysis-of-formation-methods-of-range-profiles-for-an-x-band-coastal-surveillance-radar" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134878.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">127</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">5486</span> The Operating Behaviour of Unbalanced Unpaced Merging Assembly Lines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Shaaban">S.

To optimize the interfacial properties between the active layer and the electrode, a cathode buffer layer (CBL) is introduced. This layer can reduce the leakage current, increasing the open-circuit voltage and the fill factor while improving the OSC stability. In this work, the performance of PM6:Y6 OSC with 1-Chloronaphthalene as an additive is examined. To accomplish this, three CBLs PNDIT-F3N-Br, ZrAcac, and PDINO, are compared using the conventional configuration. The device with PNDIT-F3N-Br as CBL exhibits the highest power conversion efficiency of 16.04%.

This work focuses on the energy absorption capacity of each group of buffers particularly. The quasi-static compression tests were carried out to obtain the pre-compression force and the load-defection response of the buffers. Then a finite element (FE) model was constructed using Ls_dyna program. The rubber material was modeled with a tabulated method easily, in which no more material constants need to be fitted. The simulation results agreed with the experimental results well. Numerical study of the buffers was performed using the validated FE model and the influence of the initial pressure on the buffers was obtained.

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">5482</span> Whether Buffer Zone Community Forests’ Benefits Are Distributed Fairly to Low-Income Users: Reflection From the Buffer Zone Community Forests in Bardia National Park, Nepal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Keshav%20Raj%20Acharya">Keshav Raj Acharya</a>, <a href="https://publications.waset.org/abstracts/search?q=Thakur%20Silwal"> Thakur Silwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Neelam%20C.%20Poudyal"> Neelam C.

The forest area within the buffer zone has been managed as a buffer zone community forest (BZCF) for the last 25 years after the approval of the buffer zone management regulation 1996. With a case study of select BZCF in Bardia National Park, this study aims to analyze whether the benefit provided by BZCF is equally available to poor users among other socioeconomic classes of the users. The findings are based on the analysis of cross-sectional data involving household surveys (n=305) and key informants’ interviews (n=10) as well as office records available at different 5 buffer zone community forest user groups offices. Results indicate that despite the provisions of subsidized rates for poor; poor households were more deprived due to higher forest products price particularly, the timber price in buffer zone. Evidence also indicate that due to the increased forest coverage, the incidence of wildlife damage has also increased and impacted the poor more due to lack of land ownership as well as limited alternatives. Clear community forest management guidelines with equitable benefit sharing and compensatory mechanisms to the users of poor socioeconomic class have been identified as a solution to increase the benefit to poor users in BZCFUGs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crop%20depredation" title="crop depredation">crop depredation</a>, <a href="https://publications.waset.org/abstracts/search?q=forest%20products" title=" forest products"> forest products</a>, <a href="https://publications.waset.org/abstracts/search?q=users" title=" users"> users</a>, <a href="https://publications.waset.org/abstracts/search?q=wellbeing%20ranking" title=" wellbeing ranking"> wellbeing ranking</a> </p> <a href="https://publications.waset.org/abstracts/181566/whether-buffer-zone-community-forests-benefits-are-distributed-fairly-to-low-income-users-reflection-from-the-buffer-zone-community-forests-in-bardia-national-park-nepal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181566.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">51</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">5481</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">5480</span> A Petri Net Model to Obtain the Throughput of Unreliable Production Lines in the Buffer Allocation Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joselito%20Medina-Marin">Joselito Medina-Marin</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandr%20Karelin"> Alexandr Karelin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Tarasenko"> Ana Tarasenko</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Carlos%20Seck-Tuoh-Mora"> Juan Carlos Seck-Tuoh-Mora</a>, <a href="https://publications.waset.org/abstracts/search?q=Norberto%20Hernandez-Romero"> Norberto Hernandez-Romero</a>, <a href="https://publications.waset.org/abstracts/search?q=Eva%20Selene%20Hernandez-Gress"> Eva Selene Hernandez-Gress</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A production line designer faces with several challenges in manufacturing system design.

Buffering scheme using network coding considers the reliability and proper degree distribution in Worldwide interoperability for Microwave Access (WiMAX) multi-hop network. Using network coding, a secure way of transmission is performed which helps in improving throughput and reduces the packet loss in the multicast network. At the outset, improved network coding is proposed in multicast wireless mesh network. Considering the problem of performance overhead, degree distribution makes a decision while performing buffer in the encoding / decoding process. Consequently, BuS (Buffer Scheme) based on network coding is proposed in the multi-hop network. Here the encoding process introduces buffer for temporary storage to transmit packets with proper degree distribution. The simulation results depend on the number of packets received in the encoding/decoding with proper degree distribution using buffering scheme. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=encoding%20and%20decoding" title="encoding and decoding">encoding and decoding</a>, <a href="https://publications.waset.org/abstracts/search?q=buffer" title=" buffer"> buffer</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20coding" title=" network coding"> network coding</a>, <a href="https://publications.waset.org/abstracts/search?q=degree%20distribution" title=" degree distribution"> degree distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=broadband%20wireless%20networks" title=" broadband wireless networks"> broadband wireless networks</a>, <a href="https://publications.waset.org/abstracts/search?q=multicast" title=" multicast"> multicast</a> </p> <a href="https://publications.waset.org/abstracts/48856/network-coding-with-buffer-scheme-in-multicast-for-broadband-wireless-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48856.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">410</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">5478</span> Design of a Phemt Buffer Amplifier in Mm-Wave Band around 60 GHz</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Abata">Maryam Abata</a>, <a href="https://publications.waset.org/abstracts/search?q=Moulhime%20El%20Bekkali"> Moulhime El Bekkali</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Mazer"> Said Mazer</a>, <a href="https://publications.waset.org/abstracts/search?q=Catherine%20Algani"> Catherine Algani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Mehdi"> Mahmoud Mehdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One major problem of most electronic systems operating in the millimeter wave band is the signal generation with a high purity and a stable carrier frequency. This problem is overcome by using the combination of a signal with a low frequency local oscillator (LO) and several stages of frequency multipliers. The use of these frequency multipliers to create millimeter-wave signals is an attractive alternative to direct generation signal. Therefore, the isolation problem of the local oscillator from the other stages is always present, which leads to have various mechanisms that can disturb the oscillator performance, thus a buffer amplifier is often included in oscillator outputs. In this paper, we present the study and design of a buffer amplifier in the mm-wave band using a 0.15μm pHEMT from UMS foundry. This amplifier will be used as a part of a frequency quadrupler at 60 GHz. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mm-wave%20band"
