The performance is analysed for parameters such as electrostatic surface potential, transconductance using a 2D device simulator ISE TCAD. Equivalent Oxide Thickness (EOT) of gate oxide can be reduced by the usage of high K dielectric materials. The gate engineering technique used here is the dual metal gate technology Due to their excellent scalability and better immunity to short channel effects, dual material double-gate (DM DG) MOSFETs are being easily assessed for CMOS applications beyond the 70 nm of the SIA roadmap 2008. Gate engineered devices show an improvement in the analog performance for different high k dielectrics. The gate engineered device show an increase of drain current by about 5% in the subthreshold region and a 3% increase in transconductance in strong inversion. For analog applications, importance is given to the subthreshold regime as CMOS circuits operated in this regime are very much attractive for ultralow-power high-gain performances.","PeriodicalId":184011,"journal":{"name":"2011 3rd International Conference on Electronics Computer Technology","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130465786","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}

However, for some types of systems including embedded systems, developing test cases from output domain is more suitable than developing from input domain, especially, when the output domain is smaller. This approach ensures better reliability of the system under test. In this paper, the authors present a new approach to automate the generation of test cases from output domain of a pilot project “Temperature Monitoring and Controlling of Nuclear Reactor System” (TMCNRS) which is an embedded system developed using modified Cleanroom Software Engineering methodology. An Automated Test Case Generator (ATCG) that uses Genetic algorithms (GAs) extensively and generates test cases from output domain is proposed. The ATCG generates test cases which are useful to conduct pseudo — exhaustive testing to detect single, double and several multimode faults in the system. The generator considers most of the combinations of outputs, and finds the corresponding inputs while optimizing the number of test cases generated. In order to investigate the effectiveness of this approach, test cases were generated by ATCG and the tests were conducted on the target embedded system at a minimum cost and time. Experimental results show that this approach is very promising.","PeriodicalId":184011,"journal":{"name":"2011 3rd International Conference on Electronics Computer Technology","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128945071","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}

Because of adaptive nature of mask size depending on the noise quantity in the image, adaptive median filter works better in removing the salt and pepper noise. To show the performance of DT-CWT speckle filters like median filter, Lee filter, Frost and Kuan filters and DWT are considered. Adaptive median filter is compared with other filters and also the transformations. The superiority of Dual Tree Complex Wavelet Transform in removing the Speckle noise and Adaptive Median filter in removing the Speckle noise in images are presented.

This motivates the need for association analysis. This paper presents a survey of different association rule mining techniques for market basket analysis, highlighting strengths of different association rule mining techniques. Further, we want to point out potential pitfalls as well as challenging issues need to be addressed by an association rule mining technique.

Traditionally, speaker verification systems use a single feature for representing speaker-specific information. In this work extraction of segmental and suprasegmental features is proposed which shows a significant improvement in the performance of verification. The size and shape assumed by the vocal tract while producing various sound units is generated by Mel Frequency Cepstral Coefficient (MFCC) which is a segmental feature. Pitch information contributes to the uniqueness of the speaker's voice at the suprasegmental feature which spans for a longer duration than the frames used for short term spectral analysis. The scores obtained using MFCC and Pitch based systems are fused using a confidence measure. Speaker Verification experiments were carried out on the CHAINS corpus database. The equal error rate (EER) obtained for the MFCC system is 12.8%. The MFCC system outperforms the system based on Pitch alone. The integration MFCC and Pitch for speaker verification using a confidence measure gives an EER of 11.2%.","PeriodicalId":184011,"journal":{"name":"2011 3rd International Conference on Electronics Computer Technology","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132988356","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}

Because of arbitrary interference of concurrent objects, test case explosion becomes a major problem in testing concurrent systems. Synchronization and Deadlock being the two key features of concurrent systems make the systematic testing of concurrent systems a tedious task. In this paper we present a novel approach of generating test cases for concurrent systems with the help of UML Sequence Diagram. Our approach consists of transferring the Sequence Diagram into a Concurrent Composite Graph (CCG). The CCG is traversed by an effective graph traversing technique like BFS (Breath-First-Technique) and DFS (Depth-First-search) using message sequence path criteria to generate the test cases for concurrent systems. The proposed approach is applied to concurrent systems for test case generation and found to be very effective in controlling the test case explosion problem. The generated test cases are useful to detect interaction, scenario, as well as operational faults in case of concurrent systems.","PeriodicalId":184011,"journal":{"name":"2011 3rd International Conference on Electronics Computer Technology","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133044848","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}
