It is contingent on a parsing table, whereas the parsing tables are extracted from the grammar. The parsing table specifies the actions to be taken during parsing. It requires that the parsing table should have no action conflicts for the same input symbol. This requirement imposes a condition on the class of grammars over which the LR algorithms work. However, there are grammars for which the parsing tables hold action conflicts. In such cases, the algorithm needs a capability of scanning (looking-ahead) next input symbols ahead of the current input symbol. In this paper, a ‘Left to Right’-‘Right Most’ parsing algorithm with lookahead capability is introduced. The 'look-ahead' capability in the LR parsing algorithm is the major contribution of this paper. The practicality of the proposed algorithm is substantiated by the parser implementation of the Context Free Grammar (CFG) of an already proposed programming language 'State Controlled Object Oriented Programming' (SCOOP). SCOOP’s Context Free Grammar has 125 productions and 192 item sets. This algorithm parses SCOOP while the grammar requires to ‘look ahead’ the input symbols due to action conflicts in its parsing table. Proposed LR parsing algorithm with lookahead capability can be viewed as an optimization of ‘Simple Left to Right’-‘Right Most’ (SLR) parsing algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=left%20to%20right-right%20most%20parsing" title="left to right-right most parsing">left to right-right most parsing</a>, <a href="https://publications.waset.org/abstracts/search?q=syntax%20analysis" title=" syntax analysis"> syntax analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=bottom-up%20parsing%20algorithm" title=" bottom-up parsing algorithm"> bottom-up parsing algorithm</a> </p> <a href="https://publications.waset.org/abstracts/128733/left-to-right-right-most-parsing-algorithm-with-lookahead" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128733.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">126</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">947</span> Area Efficient Carry Select Adder Using XOR Gate Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahendrapal%20Singh%20Pachlaniya">Mahendrapal Singh Pachlaniya</a>, <a href="https://publications.waset.org/abstracts/search?q=Laxmi%20Kumre"> Laxmi Kumre</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The AOI (AND – OR- INVERTER) based design of XOR gate is proposed in this paper with less number of gates. This new XOR gate required four basic gates and basic gate include only AND, OR, Inverter (AOI). Conventional XOR gate required five basic gates. Ripple Carry Adder (RCA) used in parallel addition but propagation delay time is large. RCA replaced with Carry Select Adder (CSLA) to reduce propagation delay time. CSLA design with dual RCA considering carry = ‘0’ and carry = ‘1’, so it is not an area efficient adder. To make area efficient, modified CSLA is designed with single RCA considering carry = ‘0’ and another RCA considering carry = ‘1’ replaced with Binary to Excess 1 Converter (BEC). Now replacement of conventional XOR gate by new design of XOR gate in modified CSLA reduces much area compared to regular CSLA and modified CSLA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CSLA" title="CSLA">CSLA</a>, <a href="https://publications.waset.org/abstracts/search?q=BEC" title=" BEC"> BEC</a>, <a href="https://publications.waset.org/abstracts/search?q=XOR%20gate" title=" XOR gate"> XOR gate</a>, <a href="https://publications.waset.org/abstracts/search?q=area%20efficient" title=" area efficient"> area efficient</a> </p> <a href="https://publications.waset.org/abstracts/41782/area-efficient-carry-select-adder-using-xor-gate-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41782.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">361</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">946</span> Performance Analysis of Arithmetic Units for IoT Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nithiya%20C.">Nithiya C.</a>, <a href="https://publications.waset.org/abstracts/search?q=Komathi%20B.%20J."> Komathi B.

Adders are a nearly universal component of today's integrated circuits. Most of the research was on the design of high-speed adders to execute addition based on various adder structures. This paper discusses the ideal path for selecting an arithmetic unit for IoT applications. Based on the analysis of eight types of 16-bit adders, we found out Carry Look-ahead (CLA) produces low power. Additionally, multiplier and accumulator (MAC) unit is implemented with the Booth multiplier by using the low power adders in the order of preference. The design is synthesized and verified using Synopsys Design Compiler and VCS. Then it is implemented by using Cadence Encounter. The total power consumed by the CLA based booth multiplier is 0.03527mW, the total area occupied is 11260 um², and the speed is 2034 ps. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carry%20look-ahead" title="carry look-ahead">carry look-ahead</a>, <a href="https://publications.waset.org/abstracts/search?q=carry%20select%20adder" title=" carry select adder"> carry select adder</a>, <a href="https://publications.waset.org/abstracts/search?q=CSA" title=" CSA"> CSA</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things" title=" internet of things"> internet of things</a>, <a href="https://publications.waset.org/abstracts/search?q=ripple%20carry%20adder" title=" ripple carry adder"> ripple carry adder</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20rule%20check" title=" design rule check"> design rule check</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20delay%20product" title=" power delay product"> power delay product</a>, <a href="https://publications.waset.org/abstracts/search?q=multiplier%20and%20accumulator" title=" multiplier and accumulator"> multiplier and accumulator</a> </p> <a href="https://publications.waset.org/abstracts/145683/performance-analysis-of-arithmetic-units-for-iot-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145683.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">117</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">945</span> Deradicalization for Former Terrorists through Entrepreneurship Program</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jamal%20Wiwoho">Jamal Wiwoho</a>, <a href="https://publications.waset.org/abstracts/search?q=Pujiyono"> Pujiyono</a>, <a href="https://publications.waset.org/abstracts/search?q=Triyanto"> Triyanto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Terrorism is a real enemy for all countries, including Indonesia. Bomb attacks in some parts of Indonesia are proof that Indonesia has serious problems with terrorism. Perpetrators of terror are arrested and imprisoned, and some of them were executed. However, this method did not succeed in stopping the terrorist attacks. Former terrorists continue to carry out bomb attacks. Therefore, this paper proposes a program towards deradicalization efforts of former terrorists through entrepreneurship. This is necessary because it is impossible to change their radical ideology. The program is also motivated by understanding that terrorists generally come from poor families. This program aims to occupy their time with business activities so there is no time to plan and carry out bomb attacks. This research is an empirical law study. Data were collected by literature study, observation, and in-depth interviews. Data were analyzed with the Miles and Huberman interactive model. The results show that the entrepreneurship program is effective to prevent terrorist attack. Former terrorists are busy with their business. Therefore, they have no time to carry out bomb attacks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deradicalization" title="deradicalization">deradicalization</a>, <a href="https://publications.waset.org/abstracts/search?q=terrorism" title=" terrorism"> terrorism</a>, <a href="https://publications.waset.org/abstracts/search?q=terrorists" title=" terrorists"> terrorists</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship" title=" entrepreneurship"> entrepreneurship</a> </p> <a href="https://publications.waset.org/abstracts/83652/deradicalization-for-former-terrorists-through-entrepreneurship-program" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83652.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">269</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">944</span> The Hidden Role of Interest Rate Risks in Carry Trades</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jingwen%20Shi">Jingwen Shi</a>, <a href="https://publications.waset.org/abstracts/search?q=Qi%20Wu"> Qi Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We study the role played interest rate risk in carry trade return in order to understand the forward premium puzzle. In this study, our goal is to investigate to what extent carry trade return is indeed due to compensation for risk taking and, more important, to reveal the nature of these risks. Using option data not only on exchange rates but also on interest rate swaps (swaptions), our first finding is that, besides the consensus currency risks, interest rate risks also contribute a non-negligible portion to the carry trade return. What strikes us is our second finding. We find that large downside risks of future exchange rate movements are, in fact, priced significantly in option market on interest rates. The role played by interest rate risk differs structurally from the currency risk. There is a unique premium associated with interest rate risk, though seemingly small in size, which compensates the tail risks, the left tail to be precise. On the technical front, our study relies on accurately retrieving implied distributions from currency options and interest rate swaptions simultaneously, especially the tail components of the two. For this purpose, our major modeling work is to build a new international asset pricing model where we use an orthogonal setup for pricing kernels and specify non-Gaussian dynamics in order to capture three sets of option skew accurately and consistently across currency options and interest rate swaptions, domestic and foreign, within one model. Our results open a door for studying forward premium anomaly through implied information from interest rate derivative market. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carry%20trade" title="carry trade">carry trade</a>, <a href="https://publications.waset.org/abstracts/search?q=forward%20premium%20anomaly" title=" forward premium anomaly"> forward premium anomaly</a>, <a href="https://publications.waset.org/abstracts/search?q=FX%20option" title=" FX option"> FX option</a>, <a href="https://publications.waset.org/abstracts/search?q=interest%20rate%20swaption" title=" interest rate swaption"> interest rate swaption</a>, <a href="https://publications.waset.org/abstracts/search?q=implied%20volatility%20skew" title=" implied volatility skew"> implied volatility skew</a>, <a href="https://publications.waset.org/abstracts/search?q=uncovered%20interest%20rate%20parity" title=" uncovered interest rate parity"> uncovered interest rate parity</a> </p> <a href="https://publications.waset.org/abstracts/37679/the-hidden-role-of-interest-rate-risks-in-carry-trades" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37679.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">445</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">943</span> Generation of 3d Models Obtained with Low-Cost RGB and Thermal Sensors Mounted on Drones</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Julio%20Manuel%20De%20Luis%20Ruiz">Julio Manuel De Luis Ruiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Javier%20Sedano%20Cibri%C3%A1n"> Javier Sedano Cibrián</a>, <a href="https://publications.waset.org/abstracts/search?q=Rub%C3%A9N%20P%C3%A9rez%20%C3%81lvarez"> RubéN Pérez Álvarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Ra%C3%BAl%20Pereda%20Garc%C3%ADa"> Raúl Pereda García</a>, <a href="https://publications.waset.org/abstracts/search?q=Felipe%20Pi%C3%B1a%20Garc%C3%ADa"> Felipe Piña García</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays it is common to resort to aerial photography to carry out the prospection and/or exploration of archaeological sites. In this sense, the classic 3D models are being applied to investigate the direction towards which the generally subterranean structures of an archaeological site may continue and therefore, to help in making the decisions that define the location of new excavations. In recent years, Unmanned Aerial Vehicles (UAVs) have been applied as the vehicles that carry the sensor. This implies certain advantages, such as the possibility of including low-cost sensors, given that these vehicles can carry the sensor at relatively low altitudes. Due to this, low-cost dual sensors have recently begun to be used. This new equipment can collaborate with classic Digital Elevation Models (DEMs) in the exploration of archaeological sites, but this entails the need for a methodological setting to optimise the acquisition, processing and exploitation of the information provided by low-cost dual sensors. This research focuses on the design of an appropriate workflow to obtain 3D models with low-cost sensors carried on UAVs, both in the RGB and thermal domains. All the foregoing has been applied to the archaeological site of Juliobriga, located in Cantabria (Spain). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=process%20optimization" title="process optimization">process optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=RGB%20models" title=" RGB models"> RGB models</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20models" title=" thermal models"> thermal models</a>, <a href="https://publications.waset.org/abstracts/search?q=" title=" "> </a>, <a href="https://publications.waset.org/abstracts/search?q=UAV" title=" UAV"> UAV</a>, <a href="https://publications.waset.org/abstracts/search?q=workflow" title=" workflow"> workflow</a> </p> <a href="https://publications.waset.org/abstracts/137056/generation-of-3d-models-obtained-with-low-cost-rgb-and-thermal-sensors-mounted-on-drones" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137056.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">138</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">942</span> Bioefficacy of Diclosulam for Controlling Weeds in Soybean [Glycine Max (L.)

The treatments comprised of Diclosulam 84 % WDG viz. 6.25, 12.50, 25.00 and 37.50 g/ha as pre emergence (PE), Pendimethalin 30% EC 3.33 l/ha, Sulfentrazon 48% SC 750 g/ha, hand weeding at 30 and 45 DAS and weedy check, were evaluated in randomized block design in three replications. The experimental soil was clay in texture and non-calcareous. Experimental field was mainly dominated by grasses-Echinochloa colonum, E.crusgalli,Cynodon dactylon, Sedges-Cyperus rotundus and broad leaved weeds Celosia argentea and Digera arvensis.The result revealed that application of Diclosulam 84 % WDG 25 g/ha PE was found effective in controlling mostly weed species and registered higher weed control efficiency 81.2, 74.3, 69.6 per cent at 30, 45 days after sowing and at harvest. Diclosulam 84 % WDG (6.25-25.0 g/ha) was found selective to the soybean crop as no any phytotoxicity symptoms were observed. Among the herbicidal treatments, Diclosulam 84 % WDG 25 g/ha registered maximum and significantly higher soybean seed yield (1889 and 1431 kg/ha during kharif 2020 and 2021, respectively and was at par with Sulfentrazone 48% SC 750 g/ha and over weedy check( 1027 and 667 kg/ha).The wheat crop growth, yield attributes and seed yield were not influenced due to carry over effect of the Diclosulam 84 % WDG( 6.25-25.0 g/ha) and no any phytotoxicity symptoms were observed. Henceforth, the Diclosulam 84 % WDG 25.0 g/ha as pre emergence may be used in the soybean for effective weed control without carry over effect on succeeding wheat crop. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diclosulam" title="Diclosulam">Diclosulam</a>, <a href="https://publications.waset.org/abstracts/search?q=soybean" title=" soybean"> soybean</a>, <a href="https://publications.waset.org/abstracts/search?q=carry%20over%20effect" title=" carry over effect"> carry over effect</a>, <a href="https://publications.waset.org/abstracts/search?q=succeeding%20wheat" title=" succeeding wheat"> succeeding wheat</a> </p> <a href="https://publications.waset.org/abstracts/157215/bioefficacy-of-diclosulam-for-controlling-weeds-in-soybean-glycine-max-l-merrill-and-its-carry-over-effect-on-succeeding-wheat-triticum-aestivum-crop" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157215.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">113</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">941</span> Study on the Efficient Routing Algorithms in Delay-Tolerant Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Si-Gwan%20Kim">Si-Gwan Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Delay Tolerant Networks (DTN), there may not exist an end-to-end path between source and destination at the time of message transmission.

The simulation using ONE simulator results shows that our modified version gives higher delivery ratio and less latency as compared to BSW. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=delay%20tolerant%20networks" title="delay tolerant networks">delay tolerant networks</a>, <a href="https://publications.waset.org/abstracts/search?q=store%20carry%20and%20forward" title=" store carry and forward"> store carry and forward</a>, <a href="https://publications.waset.org/abstracts/search?q=one%20simulator" title=" one simulator"> one simulator</a>, <a href="https://publications.waset.org/abstracts/search?q=binary%20spray%20and%20wait" title=" binary spray and wait"> binary spray and wait</a> </p> <a href="https://publications.waset.org/abstracts/97723/study-on-the-efficient-routing-algorithms-in-delay-tolerant-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97723.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">123</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">940</span> Development of Fixture for Pipe to Pipe Friction Stir Welding of Dissimilar Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aashutosh%20A.%20Tadse">Aashutosh A.

It involves holding the workpieces stiff enough to bear the force of the tool moving across the junction to carry out a successful weld. The weld that has flat plates as workpieces, has a quite simpler geometry in terms of fixture holding them. In the case of FSW of pipes, the pipes need to be held firm with the chucks and jaws according to the diameter of the pipes being welded; the FSW tool is then revolved around the pipes to carry out the weld. Machine requires a larger area and it becomes more costly because of such a setup. To carry out the weld on the Milling machine, the newly designed fixture must be set-up on the table of milling machine and must facilitate rotation of pipes by the motor being shafted to one end of the fixture, and the other end automatically rotated because of the rotating jaws held tight enough with the pipes. The set-up has tapered cones as the jaws that would go in the pipes thus holding it with the help of its knurled surface providing the required grip. The process has rotation of pipes with the stationary rotating tool penetrating into the junction. The FSW on pipes in this process requires a very low RPM of pipes to carry out a fine weld and the speed shall change with every combination of material and diameter of pipes, so a variable speed setting motor shall serve the purpose. To withstand the force of the tool, an attachment to the shaft is provided which will be diameter specific that will resist flow of material towards the center during the weld. The welded joint thus carried out will be proper to required standards and specifications. Current industrial requirements state the need of space efficient, cost-friendly and more generalized form of fixtures and set-ups of machines to be put up. The proposed design considers every mentioned factor and thus proves to be positive in the same. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=force%20of%20tool" title="force of tool">force of tool</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20stir%20welding" title=" friction stir welding"> friction stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=milling%20machine" title=" milling machine"> milling machine</a>, <a href="https://publications.waset.org/abstracts/search?q=rotation%20of%20pipes" title=" rotation of pipes"> rotation of pipes</a>, <a href="https://publications.waset.org/abstracts/search?q=tapered%20cones" title=" tapered cones"> tapered cones</a> </p> <a href="https://publications.waset.org/abstracts/102914/development-of-fixture-for-pipe-to-pipe-friction-stir-welding-of-dissimilar-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102914.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">114</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">939</span> Design of Speedy, Scanty Adder for Lossy Application Using QCA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Angeline%20Priyanka">T.

Complementary Metal Oxide Semiconductor (CMOS) technology has been the industry standard for implementing VLSI device for the past two decades, but due to scale-down issues of ultra-low dimension achievement is not achieved so far. Hence it paved a way for Quantum Cellular Automata (QCA). It is only one of the many alternative technologies proposed as a replacement solution to the fundamental limit problem that CMOS technology will impose in the years to come. In this brief, presented a new adder that possesses high speed of operation occupying less area is proposed. This adder is designed especially for error tolerant application. Hence in the proposed adder, the overall area (cell count) and simulation time are reduced by 88 and 73 percent respectively.

Aerial robots can move quickly and get a different sight of view of the area, but those vehicles cannot carry heavy payloads. On the other hand, unmanned ground vehicles (UGVs) are slow moving vehicles, since those can carry heavier payloads than unmanned aerial vehicles (UAVs). In this context, we investigate the performances of various Similarity Metrics to provide a common map for Heterogeneous Robot Team (HRT) in complex environments. Within the usage of Lidar Odometry and Octree Mapping technique, the local 3D maps of the environment are gathered.  In order to obtain a common map for HRT, informative theoretic similarity metrics are exploited. All types of these similarity metrics gave adequate as allowable simulation time and accurate results that can be used in different types of applications.

At present, the procedure to carry out the power performance verification of wind turbines is based on a standard of the International Electrotechnical Commission (IEC). In this paper, nonparametric statistical inference is applied to designing a simple, inexpensive method of verifying the power performance of a wind turbine. A statistical test is explained, examined, and the adequacy is tested over real data. The methods use the information that is collected by the SCADA system (Supervisory Control and Data Acquisition) from the sensors embedded in the wind turbines in order to carry out the power performance verification of a wind farm. The study has used data on the monthly output of wind farm in the Republic of Macedonia, and the time measuring interval was from January 1, 2016, to December 31, 2016. At the end, it is concluded whether the power performance of a wind turbine differed significantly from what would be expected. The results of the implementation of the proposed methods showed that the power performance of the specific wind farm under assessment was acceptable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=canonical%20correlation%20analysis" title="canonical correlation analysis">canonical correlation analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20curve" title=" power curve"> power curve</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20performance" title=" power performance"> power performance</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20energy" title=" wind energy"> wind energy</a> </p> <a href="https://publications.waset.org/abstracts/82985/wind-farm-power-performance-verification-using-non-parametric-statistical-inference" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82985.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">336</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">936</span> An Ultrasonic Signal Processing System for Tomographic Imaging of Reinforced Concrete Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Edwin%20Forero-Garcia">Edwin Forero-Garcia</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaime%20Vitola"> Jaime Vitola</a>, <a href="https://publications.waset.org/abstracts/search?q=Brayan%20Cardenas"> Brayan Cardenas</a>, <a href="https://publications.waset.org/abstracts/search?q=Johan%20Casagua"> Johan Casagua</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research article presents the integration of electronic and computer systems, which developed an ultrasonic signal processing system that performs the capture, adaptation, and analog-digital conversion to later carry out its processing and visualization. The capture and adaptation of the signal were carried out from the design and implementation of an analog electronic system distributed in stages: 1. Coupling of impedances; 2. Analog filter; 3. Signal amplifier. After the signal conditioning was carried out, the ultrasonic information was digitized using a digital microcontroller to carry out its respective processing. The digital processing of the signals was carried out in MATLAB software for the elaboration of A-Scan, B and D-Scan types of ultrasonic images. Then, advanced processing was performed using the SAFT technique to improve the resolution of the Scan-B-type images. Thus, the information from the ultrasonic images was displayed in a user interface developed in .Net with Visual Studio. For the validation of the system, ultrasonic signals were acquired, and in this way, the non-invasive inspection of the structures was carried out and thus able to identify the existing pathologies in them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acquisition" title="acquisition">acquisition</a>, <a href="https://publications.waset.org/abstracts/search?q=signal%20processing" title=" signal processing"> signal processing</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=SAFT" title=" SAFT"> SAFT</a>, <a href="https://publications.waset.org/abstracts/search?q=HMI" title=" HMI"> HMI</a> </p> <a href="https://publications.waset.org/abstracts/162674/an-ultrasonic-signal-processing-system-for-tomographic-imaging-of-reinforced-concrete-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162674.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">107</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">935</span> Gender and Advertisements: A Content Analysis of Pakistani Prime Time Advertisements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aaminah%20Hassan">Aaminah Hassan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Advertisements carry a great potential to influence our lives because they are crafted to meet particular ends. Stereotypical representation in advertisements is capable of forming unconscious attitudes among people towards any gender and their abilities. This study focuses on gender representation in Pakistani prime time advertisements. For this purpose, 13 advertisements were selected from three different categories of foods and beverages, cosmetics, cell phones and cellular networks from the prime time slots of one of the leading Pakistani entertainment channel, ‘Urdu 1’. Both quantitative and qualitative analyses are carried out for range of variables like gender, age, roles, activities, setting, appearance and voice overs. The results revealed that gender representation in advertisements is stereotypical. Moreover, in few instances, the portrayal of women is not only culturally inappropriate but is demeaning to the image of women as well. Their bodily charm is used to promote products. Comparing different entertainment channels for their prime time advertisements and broadening the scope of this research will yield greater implications for the researchers who want to carry out the similar research. It is hoped that the current study would help in the promotion of media literacy among the viewers and media authorities in Pakistan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Advertisements" title="Advertisements">Advertisements</a>, <a href="https://publications.waset.org/abstracts/search?q=Content%20Analysis" title=" Content Analysis"> Content Analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Gender" title=" Gender"> Gender</a>, <a href="https://publications.waset.org/abstracts/search?q=Prime%20time" title=" Prime time"> Prime time</a> </p> <a href="https://publications.waset.org/abstracts/91896/gender-and-advertisements-a-content-analysis-of-pakistani-prime-time-advertisements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91896.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">214</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">934</span> Perception of Violence through the Drawing: A Research with Mexican University Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yessica%20Martinez%20Soto">Yessica Martinez Soto</a>, <a href="https://publications.waset.org/abstracts/search?q=Cesar%20E.%20Jimenez%20Yanez"> Cesar E.

It is up to social scientists to be able to carry out analyzes in this regard to identify the different ways in which violence is normalized among people. The interest of this research work focuses on investigating the perception of violence in Mexican University students through the technique of drawing. To carry out this research, we worked with 67 university students from the Autonomous University of Baja California in Mexico, who drew an image of how they understood the concept of violence. His works showed us a variety of emotions, actions, and elements that relate and link with violence. One of the methodological tools to recognize and establish the link between the knowledge of a concept between discourse and practice is through graphic representations, that is, drawings. Although the drawing gives us a personal interpretation of the reality of each artist, the repetition of elements and the representation of similar situations allowed us to identify the degrees of incidence of the different types of violence and the areas in which it manifests itself. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=college%20students" title="college students">college students</a>, <a href="https://publications.waset.org/abstracts/search?q=Mexico" title=" Mexico"> Mexico</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20representations" title=" social representations"> social representations</a>, <a href="https://publications.waset.org/abstracts/search?q=violence" title=" violence"> violence</a> </p> <a href="https://publications.waset.org/abstracts/91278/perception-of-violence-through-the-drawing-a-research-with-mexican-university-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91278.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">232</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">933</span> PVMODREL© Development Based on Reliability Evaluation of a PV Module Using Accelerated Degradation Testing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abderafi%20Charki">Abderafi Charki</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Bigaud"> David Bigaud </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this oral speach is to present the PVMODREL© (PhotoVoltaic MODule RELiability) new software developed in the University of Angers. This new tool permits us to evaluate the lifetime and reliability of a PV module whatever its geographical location and environmental conditions. The electrical power output of a PV module decreases with time mainly as a result of the effects of corrosion, encapsulation discoloration, and solder bond failure. The failure of a PV module is defined as the point where the electrical power degradation reaches a given threshold value. Accelerated life tests (ALTs) are commonly used to assess the reliability of a PV module. However, ALTs provide limited data on the failure of a module and these tests are expensive to carry out. One possible solution is to conduct accelerated degradation tests. The Wiener process in conjunction with the accelerated failure time model makes it possible to carry out numerous simulations and thus to determine the failure time distribution based on the aforementioned threshold value. By this means, the failure time distribution and the lifetime (mean and uncertainty) can be evaluated. An example using the damp heat test is shown to demonstrate the usefulness PVMODREL. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lifetime" title="lifetime">lifetime</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability" title=" reliability"> reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=PV%20Module" title=" PV Module"> PV Module</a>, <a href="https://publications.waset.org/abstracts/search?q=accelerated%20life%20testing" title=" accelerated life testing"> accelerated life testing</a>, <a href="https://publications.waset.org/abstracts/search?q=accelerated%20degradation%20testing" title=" accelerated degradation testing"> accelerated degradation testing</a> </p> <a href="https://publications.waset.org/abstracts/23546/pvmodrel-development-based-on-reliability-evaluation-of-a-pv-module-using-accelerated-degradation-testing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23546.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">574</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">932</span> Optimal Designof Brush Roll for Semiconductor Wafer Using CFD Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Byeong-Sam%20Kim">Byeong-Sam Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyoungwoo%20Park"> Kyoungwoo Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research analyzes structure of flat panel display (FPD) such as LCD as quantitative through CFD analysis and modeling change to minimize the badness rate and rate of production decrease by damage of large scale plater at wafer heating chamber at semi-conductor manufacturing process.

In this context, a non-recursive key based integrated spritz stream cipher with the circulant hash function using delayed feedback with carry shift register (d-FCSR) is proposed in this paper. The novelty of this proposed stream cipher algorithm is to engender the improved keystream using d-FCSR. The proposed algorithm is coded using Verilog HDL to produce dynamic binary key stream and implemented on commercially available FPGA device Virtex 5 xc5vlx110t-2ff1136.

In the countries with scarce water resources, they often become a reason of armed conflicts. The peaceful settlement of relations connected with management and water consumption issues within and beyond the frontiers of the country is an important guarantee of the region stability. The said problem is urgent in Georgia as well because of its water objects are located at the borders and the transit run-off that is 12% of the total one. Fresh water resources are the major natural resources of Georgia. Despite of this, water supply of population at its Eastern part is an acute issue. Southeastern part of the country has been selected to carry out the research. This region is notable for deficiency of water resources in the country. The region tends to desertification which aggravates fresh water problem even more and presumably may lead to migration of local population from the area. The purpose of study was creation geographical information system (GIS) of water resources. GIS contains almost all layers of different content (water resources, springs, channels, hydrological stations, population water supply, etc.). The results of work provide an opportunity to identify the resource potential of the mentioned region, control and manage it, carry out monitoring and plan regional economy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=desertification" title="desertification">desertification</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=irrigation" title=" irrigation"> irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20resources" title=" water resources"> water resources</a> </p> <a href="https://publications.waset.org/abstracts/33721/geographical-information-system-for-sustainable-management-of-water-resources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33721.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">693</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">929</span> Scale-Up Study of Gas-Liquid Two Phase Flow in Downcomer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jayanth%20Abishek%20Subramanian">Jayanth Abishek Subramanian</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramin%20Dabirian"> Ramin Dabirian</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilias%20Gavrielatos"> Ilias Gavrielatos</a>, <a href="https://publications.waset.org/abstracts/search?q=Ram%20Mohan"> Ram Mohan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ovadia%20Shoham"> Ovadia Shoham</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Downcomers are important conduits for multiphase flow transfer from offshore platforms to the seabed. Uncertainty in the predictions of the pressure drop of multiphase flow between platforms is often dominated by the uncertainty associated with the prediction of holdup and pressure drop in the downcomer. The objectives of this study are to conduct experimental and theoretical scale-up study of the downcomer. A 4-in. diameter vertical test section was designed and constructed to study two-phase flow in downcomer. The facility is equipped with baffles for flow area restriction, enabling interchangeable annular slot openings between 30% and 61.7%. Also, state-of-the-art instrumentation, the capacitance Wire-Mesh Sensor (WMS) was utilized to acquire the experimental data. A total of 76 experimental data points were acquired, including falling film under 30% and 61.7% annular slot opening for air-water and air-Conosol C200 oil cases as well as gas carry-under for 30% and 61.7% opening utilizing air-Conosol C200 oil. For all experiments, the parameters such as falling film thickness and velocity, entrained liquid holdup in the core, gas void fraction profiles at the cross-sectional area of the liquid column, the void fraction and the gas carry under were measured. The experimental results indicated that the film thickness and film velocity increase as the flow area reduces. Also, the increase in film velocity increases the gas entrainment process. Furthermore, the results confirmed that the increase of gas entrainment for the same liquid flow rate leads to an increase in the gas carry-under. A power comparison method was developed to enable evaluation of the Lopez (2011) model, which was created for full bore downcomer, with the novel scale-up experiment data acquired from the downcomer with the restricted area for flow. Comparison between the experimental data and the model predictions shows a maximum absolute average discrepancy of 22.9% and 21.8% for the falling film thickness and velocity, respectively; and a maximum absolute average discrepancy of 22.2% for fraction of gas carried with the liquid (oil). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=two%20phase%20flow" title="two phase flow">two phase flow</a>, <a href="https://publications.waset.org/abstracts/search?q=falling%20film" title=" falling film"> falling film</a>, <a href="https://publications.waset.org/abstracts/search?q=downcomer" title=" downcomer"> downcomer</a>, <a href="https://publications.waset.org/abstracts/search?q=wire-mesh%20sensor" title=" wire-mesh sensor"> wire-mesh sensor</a> </p> <a href="https://publications.waset.org/abstracts/93259/scale-up-study-of-gas-liquid-two-phase-flow-in-downcomer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93259.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">166</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">928</span> Social Support in the Tradition for Pregnant Mother Care In East Nusa Tenggara</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sri%20Widati">Sri Widati</a>, <a href="https://publications.waset.org/abstracts/search?q=Ira%20Nurmala"> Ira Nurmala</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Se’i Tradition was considered to contribute highly to the high maternal mortality rate in South Amanuban, East Nusa Tenggara. This tradition is still preserved due to the social support that has influenced the decision to carry out the Se’i to pregnant women and post-partum women. The purpose of this study is to analyze this social support towards the Se’i Tradition on pregnant women in East Nusa Tenggara. This research was an explorative study with in-depth interviews, observations, and focus group discussions (FGD) in collecting the data. This study showed that emotional support towards Se’i was commonly given by families, specifically by the mother-in laws. Instrumental support was shown by the husbands and the traditional midwives who helped delivered the babies. Informational support was found on the pregnant women and their mother-in laws. Appraisal support was given by all the neighbors and relatives of the pregnant women by telling how comfortable it was to go through this tradition which eventually affected those women to carry it out themselves. The Se’i Tradition is still carried out and mostly supported by the relatives of the pregnant women. The first recommendation of this study is to suggest people to only follow the suggestions from the local health staff to give birth in the local health centers and not to do the tradition anymore. The second recommendation is to urge the government to give support in the form of transportation facilities for pregnant women to reach the local health staff. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=the%20Se%E2%80%99i%20tradition" title="the Se’i tradition">the Se’i tradition</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20support" title=" social support"> social support</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnant%20women" title=" pregnant women"> pregnant women</a>, <a href="https://publications.waset.org/abstracts/search?q=maternal%20mortality" title=" maternal mortality"> maternal mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=post-partum%20women" title=" post-partum women"> post-partum women</a> </p> <a href="https://publications.waset.org/abstracts/61255/social-support-in-the-tradition-for-pregnant-mother-care-in-east-nusa-tenggara" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61255.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">530</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">927</span> Design and Realization of Computer Network Security Perception Control System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=El%20Miloudi%20Djelloul">El Miloudi Djelloul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Based on analysis on applications by perception control technology in computer network security status and security protection measures, from the angles of network physical environment and network software system environmental security, this paper provides network security system perception control solution using Internet of Things (IOT), telecom and other perception technologies.

Alawfi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polycystic ovary syndrome (PCOS) is a common endocrinopathy among females in their reproductive years. The incidence cases are nearly 1.55 million among females across the globe, with 0.43 million associated disability-adjusted life-years (DALYs). This syndrome is associated with intricate mechanisms typically characterized by insulin resistance (IR), infertility, overweight and/or obesity. Lifestyle interventions are often prescribed as an adjective treatment. Nonetheless, obesity is a complex disease that encompasses multiple dimensions, such as excessive energy intake and genetics. The melanocortin 4 receptor mutation (MC4R) is an important mediator in appetite. There is emerging evidence that suggests its role in the Body Mass Index (BMI) among PCOS subjects, which poses the question of obesity and/or overweight among the PCOS patients who carry the MC4R variants may be caused by overconsumption. Thereby, using other satiety techniques may be beneficial as a part of personalized nutrition. Therefore, the aim of the current mini-review is to discuss the effect of the vegan low glycemic diet on reducing appetite among PCOS patients. The review shows that there is a gap in the knowledge of the effect of the vegan diet on PCOS patients who carry MC4R variants which need further research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polycystic%20ovarian%20syndrome%20%28PCOS%29" title="polycystic ovarian syndrome (PCOS)">polycystic ovarian syndrome (PCOS)</a>, <a href="https://publications.waset.org/abstracts/search?q=Appetite" title=" Appetite"> Appetite</a>, <a href="https://publications.waset.org/abstracts/search?q=Melanocortin%204%20Receptor%20Mutation%20%28MC4R%29." title=" Melanocortin 4 Receptor Mutation (MC4R)."> Melanocortin 4 Receptor Mutation (MC4R).</a>, <a href="https://publications.waset.org/abstracts/search?q=Obesity" title=" Obesity"> Obesity</a> </p> <a href="https://publications.waset.org/abstracts/169095/vegan-low-glycemic-index-diet-in-appetite-reduction-among-polycystic-ovarian-syndrome-pcos-patients-carrying-melanocortin-4-receptor-mc4r-variants-of-rs12970134-and-rs17782313-a-mini-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169095.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">129</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">925</span> Healthcare Service Quality in Indian Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ganesh%20Nivrutti%20Akhade">Ganesh Nivrutti Akhade</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper attempts to develop a reliable and valid instrument of measuring Healthcare service quality in India, and also analyses the impact of demographic factor of respondent on healthcare service quality.

The factors influencing the performance of subcontractors are grouped, similar to those identified with the project or an organization and on another hand, there are significant factors influencing the performance of the subcontractors. These factors incorporate management level leadership, time required to complete the project, profit, staff capability/expertise, reputation, installment method, organization history, and project procurement method strategy, security, bidding technique, insurance, bond and relationship with the major contractors. The factors influencing the management of subcontractors in building development projects includes performance of significant past projects, standard of workmanship, consistence with guidelines, regular payment to labourers, adherence to program, regularity and viability of communication with main contractor, adherence to subcontract necessities. Other factors comprise adherence to statutory environmental regulations, number of experienced sites administrative staff, inspection and maintenance of good workplace, number of artisans and workers, quality of as-built and shop drawings and ability to carry out the quantity of work and so on. This study also aimed to suggest a way forward to improve the performance of subcontractors which is the reason for exceeding budget at the project sites.

On a wind farm, these large scales carry the energy wind turbines extracts and are also responsible for transporting the turbines’ wakes, which may interact with downstream turbines and certainly with the atmospheric boundary layer (ABL). In this situation, it is important to conserve the energy that these wake’s carry and which could be altered artificially through numerical dissipation brought about by the schemes used for the spatial discretisation and temporal integration. Numerical dissipation has been reported to cause the premature recovery of turbine wakes, leading to an over prediction in the power produced by wind farms.An energy-conserving scheme is free from numerical dissipation and ensures that the energy of the wakes is increased or decreased only by the action of molecular viscosity or the action of wind turbines (body forces). The aim is to create an LES package with energy-conserving schemes to simulate wind turbine wakes correctly to gain insight into power-production, wake meandering etc. Such knowledge will be useful in designing more efficient wind farms with minimal wake interaction, which if unchecked could lead to major losses in energy production per unit area of the wind farm. For their research, the authors intend to use the Energy-Conserving Navier-Stokes code developed by the Energy Research Centre of the Netherlands. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy-conserving%20schemes" title="energy-conserving schemes">energy-conserving schemes</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling%20turbulence" title=" modelling turbulence"> modelling turbulence</a>, <a href="https://publications.waset.org/abstracts/search?q=Large%20Eddy%20Simulation" title=" Large Eddy Simulation"> Large Eddy Simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20boundary%20layer" title=" atmospheric boundary layer"> atmospheric boundary layer</a> </p> <a href="https://publications.waset.org/abstracts/17675/large-eddy-simulation-with-energy-conserving-schemes-understanding-wind-farm-aerodynamics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17675.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">465</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">922</span> Very Large Scale Integration Architecture of Finite Impulse Response Filter Implementation Using Retiming Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Jalaja">S.

Mid-range Karatsuba multiplication and Carry Save adder based on Karatsuba multiplication reduce time complexity for higher order multiplication implemented up to n-bit. As a result, we design modified N-tap Transpose and Parallel Symmetric FIR Filter Structure using Karatsuba algorithm. The mathematical formulation of the FFA Filter is derived. The proposed architecture involves significantly less area delay product (APD) then the existing block implementation. By adopting retiming technique, hardware cost is reduced further. The filter architecture is designed by using 90 nm technology library and is implemented by using cadence EDA Tool. The synthesized result shows better performance for different word length and block size. The design achieves switching activity reduction and low power consumption by applying with and without retiming for different combination of the circuit. The proposed structure achieves more than a half of the power reduction by adopting with and without retiming techniques compared to the earlier design structure. As a proof of the concept for block size 16 and filter length 64 for CKA method, it achieves a 51% as well as 70% less power by applying retiming technique, and for CSA method it achieves a 57% as well as 77% less power by applying retiming technique compared to the previously proposed design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carry%20save%20adder%20Karatsuba%20multiplication" title="carry save adder Karatsuba multiplication">carry save adder Karatsuba multiplication</a>, <a href="https://publications.waset.org/abstracts/search?q=mid%20range%20Karatsuba%20multiplication" title=" mid range Karatsuba multiplication"> mid range Karatsuba multiplication</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20FFA%20and%20transposed%20filter" title=" modified FFA and transposed filter"> modified FFA and transposed filter</a>, <a href="https://publications.waset.org/abstracts/search?q=retiming" title=" retiming"> retiming</a> </p> <a href="https://publications.waset.org/abstracts/56239/very-large-scale-integration-architecture-of-finite-impulse-response-filter-implementation-using-retiming-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56239.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">235</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">921</span> Financing Innovation: Differences across National Innovation Systems </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N%C3%BAria%20Arimany%20Serrat">Núria Arimany Serrat</a>, <a href="https://publications.waset.org/abstracts/search?q=Xavier%20Ferr%C3%A0s%20Hern%C3%A1ndez"> Xavier Ferràs Hernández</a>, <a href="https://publications.waset.org/abstracts/search?q=Petra%20A.%20Nylund"> Petra A.

Successful innovation, however, requires a significant financial commitment and the means of financing accessible to the firm may affect its ability to innovate. The access to equity financing such as venture capital has been connected to innovativeness for young firms. For established enterprises, debt financing of innovation may be a more realistic option. Continuous innovation and growth would otherwise require a constant increase of equity. We, therefore, investigate the relation between debt financing and innovation for large firms and hypothesize that those firms that carry more debt will be more innovative. The need for debt financing of innovation may be reduced for very profitable firms, which can finance innovation with cash flow. We thus hypothesize a moderating effect of profitability on the relationship between debt financing and innovation. We carry out an empirical investigation using a longitudinal data set including 167 large European firms over five years, resulting in 835 firm years. We apply generalized least squares (GLS) regression with fixed firm effects to control for firm heterogeneity. The findings support our hypotheses and we conclude that access to debt finding is an important antecedent of innovation, with profitability as a moderating factor. The results do however differ across national innovation systems and we find a strong relationship for British, Dutch, French, and Italian firms but not for German and Spanish entities. We discuss differences in the national systems of innovation and financing which contextualize the variations in the findings and thus make a nuanced contribution to the research in innovation financing. The cross-country differences calls for differentiated advice to managers, institutions, and researchers depending on the national context. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=innovation" title="innovation">innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=R%26D" title=" R&D"> R&D</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20innovation%20systems" title=" national innovation systems"> national innovation systems</a>, <a href="https://publications.waset.org/abstracts/search?q=financing" title=" financing"> financing</a> </p> <a href="https://publications.waset.org/abstracts/20581/financing-innovation-differences-across-national-innovation-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20581.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">531</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">920</span> Credit Cooperatives: A Factor for Improving the Sustainable Management of Private Forests</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Todor%20Nickolov%20Stoyanov">Todor Nickolov Stoyanov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cooperatives are present in all countries and in almost all sectors, including agriculture, forestry, food, finance, health, marketing, insurance and credit. Strong cooperatives are able to overcome many of the difficulties faced by private owners. Cooperatives use seven principles, including the 'Community Concern" principle, which enables cooperatives to work for the sustainable development of the community. The members of cooperatives may use different systems for generating year-round employment and for receiving sustainable income through performing different forestry activities. Various methods are used during the preparation of the report. These include literature reviews, statistics, secondary data and expert interviews. The members of the cooperatives are benefits exclusively from increasing the efficiency of the various products and from the overall yield of the harvest, and ultimately from achieving better profit through cooperative efforts. Cooperatives also use other types of activities that are an additional opportunity for cooperative income. There are many heterogeneous activities in the production and service sectors of the forest cooperatives under consideration. Some cooperatives serve dairies, distilleries, woodworking enterprises, tourist homes, hotels and motels, shops, ski slopes, sheep breeding, etc. Through the revenue generated by the activity, cooperatives have the opportunity to carry out various environmental and protective activities - recreation, water protection, protection of endangered and endemic species, etc., which in the case of small-scale forests cannot be achieved and the management is not sustainable. The conclusions indicate the results received in the analysis. Cooperative management of forests and forest lands gives higher incomes to individual owners. The management of forests and forest lands through cooperatives helps to carry out different environmental and protective activities. Cooperative forest management provides additional means of subsistence to the owners of poor forest lands. Cooperative management of forests and forest lands support owners to implement the forest management plans and to apply sustainable management of these territories. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cooperative" title="cooperative">cooperative</a>, <a href="https://publications.waset.org/abstracts/search?q=forestry" title=" forestry"> forestry</a>, <a href="https://publications.waset.org/abstracts/search?q=forest%20owners" title=" forest owners"> forest owners</a>, <a href="https://publications.waset.org/abstracts/search?q=principles%20of%20cooperation" title=" principles of cooperation"> principles of cooperation</a> </p> <a href="https://publications.waset.org/abstracts/92399/credit-cooperatives-a-factor-for-improving-the-sustainable-management-of-private-forests" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92399.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">919</span> Effect of Size and Soil Characteristic on Contribution of Side and Tip Resistance of the Drilled Shafts Axial Load Carrying Capacity </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehrak%20Zargaryaeghoubi">Mehrak Zargaryaeghoubi</a>, <a href="https://publications.waset.org/abstracts/search?q=Masood%20Hajali"> Masood Hajali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Drilled shafts are the most popular of deep foundations, because they have the capability that one single shaft can easily carry the entire load of a large column from a bridge or tall building. Drilled shaft may be an economical alternative to pile foundations because a pile cap is not needed, which not only reduces that expense, but also provides a rough surface in the border of soil and concrete to carry a more axial load. Due to the larger construction sizes of drilled shafts, they have an excellent axial load carrying capacity. Part of the axial load carrying capacity of the drilled shaft is resisted by the soil below the tip of the shaft which is tip resistance and the other part is resisted by the friction developed around the drilled shaft which is side resistance. The condition at the bottom of the excavation can affect the end bearing capacity of the drilled shaft. Also, type of the soil and size of the drilled shaft can affect the frictional resistance. The main loads applied on the drilled shafts are axial compressive loads. It is important to know how many percent of the maximum applied load will be shed inside friction and how much will be transferred to the base. The axial capacity of the drilled shaft foundation is influenced by the size of the drilled shaft, and soil characteristics. In this study, the effect of the size and soil characteristic will be investigated on the contribution of side resistance and end-bearing capacity. Also, the study presents a three-dimensional finite element modeling of a drilled shaft subjected to axial load using ANSYS. The top displacement and settlement of the drilled shaft are verified with analytical results. The soil profile is considered as Table 1 and for a drilled shaft with 7 ft diameter and 95 ft length the stresses in z-direction are calculated through the length of the shaft. From the stresses in z-direction through the length of the shaft the side resistance can be calculated and with the z-direction stress at the tip, the tip resistance can be calculated. The result of the side and tip resistance for this drilled shaft are compared with the analytical results. <p class="card-text"><strong>Keywords:</strong> <a
