In this paper, we have presented an experimental setup for temperature control of thermal systems. The electronics includes the firing - angle control circuitry to control the AC power to the filament bulb acting as a heating element. The system is identified as first order using the step response method. Different experiments like on-off control, PID control and digital control have been performed on this setup and the experimental results match with the simulation results. This experimental setup is interfaced with the MATLAB using the DAQ card. A GUI is developed in the MATLAB to make this setup user friendly, providing option like gain setting, anti-windup compensator enable/disable, selection of controller type, selection of sampling time etc. The purpose of this paper is to develop a low cost setup to demonstrate control concepts on a thermal system.","PeriodicalId":207616,"journal":{"name":"2011 IEEE 14th International Multitopic Conference","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127854436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High throughput is achieved by increasing the decoder parallelism and reducing window sizes. A batcher-sorting-based permutation network is presented which is able to support multi-standard applications. The proposed solution supports all codes specified by 3GPP LTE standard. High coding efficiency is achieved at low computational cost by exploiting an effective scheme for the initialization of forward and backward state metrics. The decoder achieves a maximum throughput of 285 Mbps at 200 MHz, occupying an area of 210 mm2 on 90-nm Standard Cell ASIC technology.","PeriodicalId":207616,"journal":{"name":"2011 IEEE 14th International Multitopic Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124386363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Static allocation of the frequency spectrum does not meet the growing demands of current wireless technology that's why spectrum sensing and dynamic allocation will become indispensible part of future wireless networks. Cognitive radio can sense the spectrum and detect the idle frequency bands which are allocated to primary users, if not; secondary users can be allocated unoccupied frequency bands in order to avoid any interference. Our primary goal is to develop efficient way of sensing holes for orthogonal frequency division multiplexing (OFDM) systems for spectrum sharing regimes. Using Cyclostationary features we are able to detect primary user. Here Cyclostationary features for primary user detection are exploited through AWGN communication channel with various noise levels. We have considered an OFDM system and exploited its parameters to examine how it relates to primary user detection and its detection probability with various different noise levels is calculated.","PeriodicalId":207616,"journal":{"name":"2011 IEEE 14th International Multitopic Conference","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124420111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Time complexity of collision detection algorithms in such scenarios is an important factor and algorithms that provide constant time collision query processing are required. This paper presents a constant time collision detection algorithm for high vertex count and complex geometrical models by using uniform spatial grids and polygon surface subdivision technique. The algorithm thus shifts the performance balance in favor of the time constraints with a compromise on space complexity. We show the results of the proposed technique on a 400K+ vertex building model.","PeriodicalId":207616,"journal":{"name":"2011 IEEE 14th International Multitopic Conference","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126831247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such loads tend to destabilize the system due to their negative dynamic input resistance characteristics as viewed from the main bus or an input filter. In this paper, we have studied the interactions of bus filter with a dc-dc converter acting as constant-power load in the presence of power conditioning equipment. As a result it is demonstrated that the impedance of bus conditioning equipment has a significant influence on the stability of the whole system. A qualitative study of this effect is presented in this paper for sunlight mode as well as for eclipse mode of operation. The theoretical conclusions of this paper are verified with the simulation results.","PeriodicalId":207616,"journal":{"name":"2011 IEEE 14th International Multitopic Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121590855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Knowing the subcellular localization of proteins is important in molecular cell biology, proteomics, and system biology and drug discovery. Different predictors have been developed that predict presence, location and interaction of molecules using various computational techniques including probabilistic models of Machine Learning and artificial intelligence algorithms. These predictors partially cover the different aspects of exploration of subcellular locations. Some of them are equally well applicable to many types of organisms (human, yeast, mouse, bacteria) while some are specific and focus on better performance in accuracy of the predicted results. Similarly some of the techniques cover “few” number of proteins but more accurately and on the other side some algorithms predict sub cellular locations of “many” proteins at the expense of prediction accuracy. This research is a review of most common and efficient techniques grouped in four in total, which are 1-amino acid composition and order-based predictors 2-sorting signal predictors 3- homology-based predictors and 4-hybrid methods that use several sources of information to predict localization. The work Elucidate the performance and coverage comparisons among the subcellular locations predictors.","PeriodicalId":207616,"journal":{"name":"2011 IEEE 14th International Multitopic Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116057720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
