A decade ago CPUs speed could not accelerate without extra ordinary cooling and consequently hit a clock speed barrier. The multi-core architecture is introduced to improve computing performance by providing hardware parallelism through more CPU cores, each having restrained clock speed. This has been a break through in High Performance Computing (HPC). While more processor cores rendered effective execution results, multi-core technology inaugurated an extra layer of complexity for programming issues. To exploit each core in a multi-core environment, application software should be optimized by using multithreading. Multi-core processors can even degrade the performance for single threaded application due to reduction in clock speed. In this paper we compare performance of multithreading fine-grained and course-grained computational problems further flavored as computation-intensive and data-intensive problems by using MPI and hybrid MPI+OpenMP approach and evaluate suitability of multi-core cluster depending on the nature of the problems.","PeriodicalId":137916,"journal":{"name":"2011 International Conference on Recent Trends in Information Systems","volume":"35 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":"132627037","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}

Various techniques have been proposed to eliminate or compensate the INU, most of which are surface fitting algorithms over the entire region. This paper proposes an ensemble of multiple Gaussian surfaces for estimation of INU and subsequently correction in MR images. The individual Gaussian surface is estimated independently over the different homogeneous regions by considering its centre as the centre of mass of the respective homogeneous region. The INU is modeled as a slowly varying multiplicative noise along with the actual tissue signals. Image histogram is considered to extract potential homogeneous regions and then for each of these regions a Gaussian surface is fitted based on the pixel gradients to estimate its INU field or bias field. These bias fields are then ensembled to obtain entire INU field within the MR image. The INU field or bias field is then iteratively removed to obtain the INU-corrected image. The experiments using 2-D synthetic phantoms and real MR images show, that the proposed method performs quite satisfactorily.","PeriodicalId":137916,"journal":{"name":"2011 International Conference on Recent Trends in Information Systems","volume":"1 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":"117145983","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}

It is shown that by selection of a fitness function which controls more than one parameter of the array pattern, and also by proper setting of weight factors in fitness function, one can achieve very good results. For each optimal design, optimal current excitation weights and optimal radii are determined having the objective of maximum Sidelobe Level (SLL) reduction. The extensive computational results show that the CCAA designs having central element feeding with non-isotropic elements yield much more reduction in SLL as compared to the same not having central element feeding. Moreover, the particular CCAA containing 4, 6 and 8 number of elements in three successive rings along with central element feeding yields grand minimum SLL (−49.29 dB). Standard Particle Swarm Optimization (PSO) is adopted to compare the results of the IPSO algorithm.","PeriodicalId":137916,"journal":{"name":"2011 International Conference on Recent Trends in Information Systems","volume":"77 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":"125491897","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}
