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">522</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">1397</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">1396</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.

We report in this study, results of a procedure for the determination of benzatropine in hair using LLE, once with methanol and second with phosphate buffer (pH 6.0), followed by filtration and then re-extraction with dichloromethane. A GC/MS method was developed and validated for this determination using selected ion monitoring (SIM) detection without derivatization. Linearity established over the concentration range 0.1-20.0 ng/mg hair, and the correlation coefficients were greater than 0.99. Recoveries were 52.2% and 21.1% using methanol and phosphate buffer extraction, respectively. Detection limits of benzatropine in hair were between 0.65 and 3.0 ng/mg hair, while the accuracy were 10.4% and 18.5% (RSD), respectively. We also applied this method to the analysis of soaked hair samples and demonstrated that the LLE using methanol meets the requirement for the analysis of benzatropine in hair. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hair%20analysis" title="hair analysis">hair analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=benzatropine" title=" benzatropine"> benzatropine</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid-liquid%20extraction" title=" liquid-liquid extraction"> liquid-liquid extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=GC%2FMS" title=" GC/MS"> GC/MS</a> </p> <a href="https://publications.waset.org/abstracts/20152/determination-of-benzatropine-in-hair-by-gcms-after-liquid-liquid-extraction-lle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20152.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">402</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">1394</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).

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">1392</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">1391</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.

It was found that the best configurations are a balanced line arrangement and a monotone decreasing order for each of the parallel merging lines, with the first generally resulting in a lower throughput and the second leading to a lower average buffer level than those of a balanced line. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=average%20buffer%20level" title="average buffer level">average buffer level</a>, <a href="https://publications.waset.org/abstracts/search?q=merging%20lines" title=" merging lines"> merging 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=throughput" title=" throughput"> throughput</a>, <a href="https://publications.waset.org/abstracts/search?q=unbalanced" title=" unbalanced"> unbalanced</a> </p> <a href="https://publications.waset.org/abstracts/42374/the-operating-behaviour-of-unbalanced-unpaced-merging-assembly-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42374.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">322</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">1390</span> Different Cathode Buffer Layers in Organic Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Radia%20Kamel">Radia Kamel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Considerable progress has been made in the development of bulk-heterojunction organic solar cells (OSCs) based on a blend of p-type and n-type organic semiconductors. 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%. The results demonstrate that modifying the cathode buffer layer is crucial for achieving high-performance OSCs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bulk%20heterojunction" title="bulk heterojunction">bulk heterojunction</a>, <a href="https://publications.waset.org/abstracts/search?q=cathode%20buffer%20layer" title=" cathode buffer layer"> cathode buffer layer</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20solar%20cells" title=" organic solar cells"> organic solar cells</a> </p> <a href="https://publications.waset.org/abstracts/131695/different-cathode-buffer-layers-in-organic-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131695.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">167</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">1389</span> Experimental and Numerical Study on 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 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. In addition, the interaction between the two groups of buffers was also investigated and the optimum distribution of the two was found. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=initial%20pressure" title="initial pressure">initial pressure</a>, <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=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=tabulated%20method" title=" tabulated method"> tabulated method</a> </p> <a href="https://publications.waset.org/abstracts/88310/experimental-and-numerical-study-on-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/88310.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">145</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">1388</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">54</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">1387</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. One of them is the assignment of buffer slots in between every machine of the production line in order to maximize the throughput of the whole line, which is known as the Buffer Allocation Problem (BAP). The BAP is a combinatorial problem that depends on the number of machines and the total number of slots to be distributed on the production line. In this paper, we are proposing a Petri Net (PN) Model to obtain the throughput in unreliable production lines, based on PN mathematical tools and the decomposition method. The results obtained by this methodology are similar to those presented in previous works, and the number of machines is not a hard restriction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buffer%20allocation%20problem" title="buffer allocation problem">buffer allocation problem</a>, <a href="https://publications.waset.org/abstracts/search?q=Petri%20Nets" title=" Petri Nets"> Petri Nets</a>, <a href="https://publications.waset.org/abstracts/search?q=throughput" title=" throughput"> throughput</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20lines" title=" production lines"> production lines</a> </p> <a href="https://publications.waset.org/abstracts/79811/a-petri-net-model-to-obtain-the-throughput-of-unreliable-production-lines-in-the-buffer-allocation-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79811.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">308</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">1386</span> Network Coding with Buffer Scheme in Multicast for Broadband Wireless Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gunasekaran%20Raja">Gunasekaran Raja</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramkumar%20Jayaraman"> Ramkumar Jayaraman</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajakumar%20Arul"> Rajakumar Arul</a>, <a href="https://publications.waset.org/abstracts/search?q=Kottilingam%20Kottursamy"> Kottilingam Kottursamy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Broadband Wireless Network (BWN) is the promising technology nowadays due to the increased number of smartphones. 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">1385</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" title="Mm-wave band">Mm-wave band</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20oscillator" title=" local oscillator"> local oscillator</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20quadrupler" title=" frequency quadrupler"> frequency quadrupler</a>, <a href="https://publications.waset.org/abstracts/search?q=buffer%20amplifier" title=" buffer amplifier"> buffer amplifier</a> </p> <a href="https://publications.waset.org/abstracts/26079/design-of-a-phemt-buffer-amplifier-in-mm-wave-band-around-60-ghz" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26079.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">545</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">1384</span> Multi Objective Simultaneous Assembly Line Balancing and Buffer Sizing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saif%20Ullah">Saif Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Guan%20Zailin"> Guan Zailin</a>, <a href="https://publications.waset.org/abstracts/search?q=Xu%20Xianhao"> Xu Xianhao</a>, <a href="https://publications.waset.org/abstracts/search?q=He%20Zongdong"> He Zongdong</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang%20Baoxi"> Wang Baoxi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Assembly line balancing problem is aimed to divide the tasks among the stations in assembly lines and optimize some objectives. In assembly lines the workload on stations is different from each other due to different tasks times and the difference in workloads between stations can cause blockage or starvation in some stations in assembly lines. Buffers are used to store the semi-finished parts between the stations and can help to smooth the assembly production. The assembly line balancing and buffer sizing problem can affect the throughput of the assembly lines. Assembly line balancing and buffer sizing problems have been studied separately in literature and due to their collective contribution in throughput rate of assembly lines, balancing and buffer sizing problem are desired to study simultaneously and therefore they are considered concurrently in current research. Current research is aimed to maximize throughput, minimize total size of buffers in assembly line and minimize workload variations in assembly line simultaneously. A multi objective optimization objective is designed which can give better Pareto solutions from the Pareto front and a simple example problem is solved for assembly line balancing and buffer sizing simultaneously. Current research is significant for assembly line balancing research and it can be significant to introduce optimization approaches which can optimize current multi objective problem in future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assembly%20line%20balancing" title="assembly line balancing">assembly line balancing</a>, <a href="https://publications.waset.org/abstracts/search?q=buffer%20sizing" title=" buffer sizing"> buffer sizing</a>, <a href="https://publications.waset.org/abstracts/search?q=Pareto%20solutions" title=" Pareto solutions "> Pareto solutions </a> </p> <a href="https://publications.waset.org/abstracts/14084/multi-objective-simultaneous-assembly-line-balancing-and-buffer-sizing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14084.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">491</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">1383</span> Best Option for Countercyclical Capital Buffer Implementation: Scenarios for Baltic States</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C4%A2irts%20Brasli%C5%86%C5%A1">Ģirts Brasliņš</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilja%20Arefjevs"> Ilja Arefjevs</a>, <a href="https://publications.waset.org/abstracts/search?q=Nade%C5%BEda%20Tarakanova"> Nadežda Tarakanova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of countercyclical capital buffer is to encourage banks to build up buffers in good times that can be drawn down in bad times. The aim of the report is to assess such decisions by banks derived from three approaches. The approaches are the aggregate credit-to-GDP ratio, credit growth as well as banking sector profits. The approaches are implemented for Estonia, Latvia and Lithuania for the time period 2000-2012. The report compares three approaches and analyses their relevance to the Baltic states by testing the correlation between a growth in studied variables and a growth of corresponding gaps. Methods used in the empirical part of the report are econometric analysis as well as economic analysis, development indicators, relative and absolute indicators and other methods. The research outcome is a cross-Baltic comparison of two alternative approaches to establish or release a countercyclical capital buffer by banks and their implications for each Baltic country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=basel%20III" title="basel III">basel III</a>, <a href="https://publications.waset.org/abstracts/search?q=countercyclical%20capital%20buffer" title=" countercyclical capital buffer"> countercyclical capital buffer</a>, <a href="https://publications.waset.org/abstracts/search?q=banks" title=" banks"> banks</a>, <a href="https://publications.waset.org/abstracts/search?q=credit%20growth" title=" credit growth"> credit growth</a>, <a href="https://publications.waset.org/abstracts/search?q=baltic%20states" title=" baltic states"> baltic states</a> </p> <a href="https://publications.waset.org/abstracts/24826/best-option-for-countercyclical-capital-buffer-implementation-scenarios-for-baltic-states" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24826.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">396</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">1382</span> Buffer Allocation and Traffic Shaping Policies Implemented in Routers Based on a New Adaptive Intelligent Multi Agent Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Taheri%20Tehrani">M.

Ajorloo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, an intelligent multi-agent framework is developed for each router in which agents have two vital functionalities, traffic shaping and buffer allocation and are positioned in the ports of the routers. With traffic shaping functionality agents shape the traffic forward by dynamic and real time allocation of the rate of generation of tokens in a Token Bucket algorithm and with buffer allocation functionality agents share their buffer capacity between each other based on their need and the conditions of the network. This dynamic and intelligent framework gives this opportunity to some ports to work better under burst and more busy conditions. These agents work intelligently based on Reinforcement Learning (RL) algorithm and will consider effective parameters in their decision process. As RL have limitation considering much parameter in its decision process due to the volume of calculations, we utilize our novel method which invokes Principle Component Analysis (PCA) on the RL and gives a high dimensional ability to this algorithm to consider as much as needed parameters in its decision process. This implementation when is compared to our previous work where traffic shaping was done without any sharing and dynamic allocation of buffer size for each port, the lower packet drop in the whole network specifically in the source routers can be seen. These methods are implemented in our previous proposed intelligent simulation environment to be able to compare better the performance metrics. The results obtained from this simulation environment show an efficient and dynamic utilization of resources in terms of bandwidth and buffer capacities pre allocated to each port. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=principal%20component%20analysis" title="principal component analysis">principal component analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement%20learning" title=" reinforcement learning"> reinforcement learning</a>, <a href="https://publications.waset.org/abstracts/search?q=buffer%20allocation" title=" buffer allocation"> buffer allocation</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-%20agent%20systems" title=" multi- agent systems"> multi- agent systems</a> </p> <a href="https://publications.waset.org/abstracts/26050/buffer-allocation-and-traffic-shaping-policies-implemented-in-routers-based-on-a-new-adaptive-intelligent-multi-agent-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26050.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">518</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">1381</span> Quantitative Analysis of Multiprocessor Architectures for Radar Signal Processing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deepak%20Kumar">Deepak Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Debasish%20Deb"> Debasish Deb</a>, <a href="https://publications.waset.org/abstracts/search?q=Reena%20Mamgain"> Reena Mamgain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Radar signal processing requires high number crunching capability. Most often this is achieved using multiprocessor platform. Though multiprocessor platform provides the capability of meeting the real time computational challenges, the architecture of the same along with mapping of the algorithm on the architecture plays a vital role in efficiently using the platform. Towards this, along with standard performance metrics, few additional metrics are defined which helps in evaluating the multiprocessor platform along with the algorithm mapping. A generic multiprocessor architecture can not suit all the processing requirements. Depending on the system requirement and type of algorithms used, the most suitable architecture for the given problem is decided. In the paper, we study different architectures and quantify the different performance metrics which enables comparison of different architectures for their merit. We also carried out case study of different architectures and their efficiency depending on parallelism exploited on algorithm or data or both. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radar%20signal%20processing" title="radar signal processing">radar signal processing</a>, <a href="https://publications.waset.org/abstracts/search?q=multiprocessor%20architecture" title=" multiprocessor architecture"> multiprocessor architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20imbalance" title=" load imbalance"> load imbalance</a>, <a href="https://publications.waset.org/abstracts/search?q=buffer%20requirement" title=" buffer requirement"> buffer requirement</a>, <a href="https://publications.waset.org/abstracts/search?q=pipeline" title=" pipeline"> pipeline</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel" title=" parallel"> parallel</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid" title=" hybrid"> hybrid</a>, <a href="https://publications.waset.org/abstracts/search?q=cluster%20of%20processors%20%28COPs%29" title=" cluster of processors (COPs)"> cluster of processors (COPs)</a> </p> <a href="https://publications.waset.org/abstracts/21687/quantitative-analysis-of-multiprocessor-architectures-for-radar-signal-processing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21687.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">412</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">1380</span> Influence of Thermal History on the Undrained Shear Strength of the Bentonite-Sand Mixture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Ravi">K. Ravi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabu%20Subhash"> Sabu Subhash</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Densely compacted bentonite or bentonite–sand mixture has been identified as a suitable buffer in the deep geological repository (DGR) for the safe disposal of high-level nuclear waste (HLW) due to its favourable physicochemical and hydro-mechanical properties. The addition of sand to the bentonite enhances the thermal conductivity and compaction properties and reduces the drying shrinkage of the buffer material. The buffer material may undergo cyclic wetting and drying upon ingress of groundwater from the surrounding rock mass and from evaporation due to high temperature (50–210 °C) derived from the waste canister. The cycles of changes in temperature may result in thermal history, and the hydro-mechanical properties of the buffer material may be affected. This paper examines the influence of thermal history on the undrained shear strength of bentonite and bentonite-sand mixture. Bentonite from Rajasthan state and sand from the Assam state of India are used in this study. The undrained shear strength values are obtained by conducting unconfined compressive strength (UCS) tests on cylindrical specimens (dry densities 1.30 and 1.5 Mg/m3) of bentonite and bentonite-sand mixture consisting of 30 % bentonite+ 70 % sand. The specimens are preheated at temperatures varying from 50-150 °C for one, two and four hours in hot air oven. The results indicate that the undrained shear strength is increased by the thermal history of the buffer material. The specimens of bentonite-sand mixture exhibited more increase in strength compared to the pure bentonite specimens. This indicates that the sand content of the mixture plays a vital role in taking the thermal stresses of the bentonite buffer in DGR conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bentonite" title="bentonite">bentonite</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20geological%20repository" title=" deep geological repository"> deep geological repository</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20history" title=" thermal history"> thermal history</a>, <a href="https://publications.waset.org/abstracts/search?q=undrained%20shear%20strength" title=" undrained shear strength"> undrained shear strength</a> </p> <a href="https://publications.waset.org/abstracts/65498/influence-of-thermal-history-on-the-undrained-shear-strength-of-the-bentonite-sand-mixture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65498.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">345</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">1379</span> Investigation of the Effect of Nickel Electrodes as a Stainless Steel Buffer Layer on the Shielded Metal Arc Welding</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meisam%20Akbari">Meisam Akbari</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Hossein%20Elahi"> Seyed Hossein Elahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mashadgarmeh"> Mohammad Mashadgarmeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the effect of nickel-electrode as a stainless steel buffer layer is considered.

Buffer zones play a critical role in preserving the outstanding universal value, authenticity, and integrity of heritage sites, shielding them from threats such as urbanization, industrialization, and tourism. The 2015 Strategy emphasizes the integration of culture and heritage into sustainable development policies, highlighting the importance of community participation, traditional knowledge, and effective management in the conservation of heritage sites. This paper examines the implications of this strategic alignment for tentative World Heritage Sites in India. It explores how buffer zones can serve as tools for sustainable tourism, economic growth, and environmental protection while also addressing the socio-economic needs of local communities. By adopting a people-centered approach, the study underscores the need for active community involvement in heritage conservation, recognizing local residents as long-term custodians of cultural heritage. The role of buffer zones in promoting sustainable livelihoods, enhancing resilience to environmental changes, and fostering a sense of belonging among communities is also discussed. The challenges associated with buffer zones, including restrictive boundaries, unclear legislative frameworks, and potential disconnection from sociocultural contexts, are critically analyzed. The paper advocates for a holistic and integrated approach to buffer zone management, ensuring that policies are not only theoretically sound but also practically feasible. It concludes by emphasizing the need for collaborative efforts among conservation professionals, local communities, and policymakers to achieve sustainable development goals that respect both the heritage site's integrity and the well-being of surrounding populations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buffer%20zones" title="buffer zones">buffer zones</a>, <a href="https://publications.waset.org/abstracts/search?q=India" title=" India"> India</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20communities" title=" local communities"> local communities</a>, <a href="https://publications.waset.org/abstracts/search?q=urbanization" title=" urbanization"> urbanization</a>, <a href="https://publications.waset.org/abstracts/search?q=world%20heritage%20sites" title=" world heritage sites"> world heritage sites</a> </p> <a href="https://publications.waset.org/abstracts/189354/integrating-heritage-conservation-and-sustainable-development-the-role-of-buffer-zones-in-safeguarding-the-tentative-world-heritage-sites-and-empowering-local-communities-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189354.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">29</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">1377</span> Determination of Optimum Water Consumptive Using Deficit Irrigation Model for Barely: A Case Study in Arak, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Najarchi">Mohsen Najarchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research was carried out in five fields (5-15 hectares) in Arak located in center of Iran, to determine optimum level of water consumed for Barely in four stages growth (vegetative, yield formation, flowering, and ripening). Actual evapotranspiration was calculated using measured water requirement in the fields. Five levels of water requirement equal to 50, 60, 70, 80, and 90 percents formed the treatments. To determine the optimum level of water requirement linear programming was used. The study showed 60 percent water requirement (40 percent deficit irrigation) has been the optimum level of irrigation for winter wheat in four stages of growth. Comparison between all of the treatments indicated above with normal condition (100% water requirement) shows increasing in water use efficiency. Although 40% deficit irrigation treatment lead to decrease of 38% in yield, net benefit was increasing in 11.37%. Furthermore, in comparison with normal condition, 70% of water requirement increased water use efficiency as 30%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimum" title="optimum">optimum</a>, <a href="https://publications.waset.org/abstracts/search?q=deficit%20irrigation" title=" deficit irrigation"> deficit irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20use%20efficiency" title=" water use efficiency"> water use efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=evapotranspiration" title=" evapotranspiration"> evapotranspiration</a> </p> <a href="https://publications.waset.org/abstracts/14760/determination-of-optimum-water-consumptive-using-deficit-irrigation-model-for-barely-a-case-study-in-arak-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14760.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">396</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">1376</span> The Effect of Porous Alkali Activated Material Composition on Buffer Capacity in Bioreactors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Girts%20Bumanis">Girts Bumanis</a>, <a href="https://publications.waset.org/abstracts/search?q=Diana%20Bajare"> Diana Bajare</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With demand for primary energy continuously growing, search for renewable and efficient energy sources has been high on agenda of our society. One of the most promising energy sources is biogas technology. Residues coming from dairy industry and milk processing could be used in biogas production; however, low efficiency and high cost impede wide application of such technology. One of the main problems is management and conversion of organic residues through the anaerobic digestion process which is characterized by acidic environment due to the low whey pH (<6) whereas additional pH control system is required. Low buffering capacity of whey is responsible for the rapid acidification in biological treatments; therefore alkali activated material is a promising solution of this problem. Alkali activated material is formed using SiO2 and Al2O3 rich materials under highly alkaline solution. After material structure forming process is completed, free alkalis remain in the structure of materials which are available for leaching and could provide buffer capacity potential. In this research porous alkali activated material was investigated. Highly porous material structure ensures gradual leaching of alkalis during time which is important in biogas digestion process. Research of mixture composition and SiO2/Na2O and SiO2/Al2O ratio was studied to test the buffer capacity potential of alkali activated material. This research has proved that by changing molar ratio of components it is possible to obtain a material with different buffer capacity, and this novel material was seen to have considerable potential for using it in processes where buffer capacity and pH control is vitally important. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alkaline%20material" title="alkaline material">alkaline material</a>, <a href="https://publications.waset.org/abstracts/search?q=buffer%20capacity" title=" buffer capacity"> buffer capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas%20production" title=" biogas production"> biogas production</a>, <a href="https://publications.waset.org/abstracts/search?q=bioreactors" title=" bioreactors"> bioreactors</a> </p> <a href="https://publications.waset.org/abstracts/9251/the-effect-of-porous-alkali-activated-material-composition-on-buffer-capacity-in-bioreactors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9251.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">242</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">1375</span> A Virtual Grid Based Energy Efficient Data Gathering Scheme for Heterogeneous Sensor Networks </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siddhartha%20Chauhan">Siddhartha Chauhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nitin%20Kumar%20Kotania"> Nitin Kumar Kotania</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditional Wireless Sensor Networks (WSNs) generally use static sinks to collect data from the sensor nodes via multiple forwarding. 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">1374</span> Countercyclical Capital Buffer in the Polish Banking System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mateusz%20Mokrogulski">Mateusz Mokrogulski</a>, <a href="https://publications.waset.org/abstracts/search?q=Piotr%20%C5%9Aliwka"> Piotr Śliwka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this paper is the identification of periods of excessive credit growth in the Polish banking sector in years 2007-2014 using different methodologies. Due to the lack of precise guidance in CRD IV regarding methods of calculating the credit gap and related deviations from the long-term trends, a few filtering methods are applied, e.g. Hodrick-Prescott and Baxter-King. The solutions based on the switching model are also proposed. The next step represent computations of both the credit gap, and the counter cyclical capital buffer (CCB) rates on a quarterly basis. The calculations are carried out for the entire banking sector in Poland, as well as for its components (commercial and co-operative banks), and different types of loans. The calculations show vividly that in the analysed period there were the times of excessive credit growth. However, the results are different for the above mentioned sub-sectors. Of paramount importance here are mortgage loans, where the outcomes are distorted by high exchange rate fluctuations. The research on the CCB is now going to gain popularity as the buffer will soon become one of the tools of the macro prudential policy under CRD IV. Although the presented method is focused on the Polish banking sector, it can also be applied to other member states. Especially to the Central and Eastern European countries, that are usually characterized by smaller banking sectors compared to EU-15. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=countercyclical%20capital%20buffer" title="countercyclical capital buffer">countercyclical capital buffer</a>, <a href="https://publications.waset.org/abstracts/search?q=CRD%20IV" title=" CRD IV"> CRD IV</a>, <a href="https://publications.waset.org/abstracts/search?q=filtering%20methods" title=" filtering methods"> filtering methods</a>, <a href="https://publications.waset.org/abstracts/search?q=mortgage%20loans" title=" mortgage loans"> mortgage loans</a> </p> <a href="https://publications.waset.org/abstracts/33054/countercyclical-capital-buffer-in-the-polish-banking-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33054.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">322</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">1373</span> Implementing a Database from a Requirement Specification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Omer">M.

As a result of simulation, excellent performance can be obtained when the conduction band of window layer positions higher by 0.2 eV than that of CIGS and shallow donor density in the CdS was found about 1×10¹⁸ (cm⁻³). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CIGS%20solar%20cells" title="CIGS solar cells">CIGS solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20film" title=" thin film"> thin film</a>, <a href="https://publications.waset.org/abstracts/search?q=SCAPS" title=" SCAPS"> SCAPS</a>, <a href="https://publications.waset.org/abstracts/search?q=buffer%20layer" title=" buffer layer"> buffer layer</a>, <a href="https://publications.waset.org/abstracts/search?q=conduction%20band%20offset" title=" conduction band offset"> conduction band offset</a> </p> <a href="https://publications.waset.org/abstracts/82360/optimization-of-cu-in-gase2-based-thin-film-solar-cells-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82360.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">230</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">1370</span> Elicitation Methods of Requirements Gathering in Shopping Mobile Application Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xiao%20Yihong">Xiao Yihong</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Zhixuan"> Li Zhixuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Wong%20Kah%20Seng"> Wong Kah Seng</a>, <a href="https://publications.waset.org/abstracts/search?q=Shen%20Xingcang"> Shen Xingcang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Requirement Elicitation is one of the important factors in developing any new application. Most systems fail just because of wrong elicitation practice. As a result, developers always choose different methods in different fields to achieve optimal results. This paper analyses four cases to understand the effectiveness of different requirement elicitation methods in the field of mobile shopping applications. The elicitation methods we studied included interviews, questionnaires, prototypes, analysis of existing systems, focus groups, brainstorming, and so on. Through the research and analysis results, we ensured the need for a mixture of elicitation methods. Meanwhile, the method adopted should be determined according to the scale of the project and be operated in a reasonable order to ensure the high efficiency of requirement elicitation. <p
