Since RAMs are critical to processor performance, researchers have sought to optimize their performance and efficiency through reconfiguration [1]. This paper presents the architecture and circuit design for a multiported SRAM building block. In this paper SRAM cell with load (6T) and without load (4T) is designed and implemented in 180nm technology and comparison between them was made in terms of power consumed, area used and access time. It was found that load less 4T SRAM cell consumes less power as compared to 6T SRAM cell and occupies lesser area. Here as an application example, 8X1 memory using load less 4T is implemented. The decoding here is again done with Traditional CMOS decoder and Lyon Schediwy decoder. It is observed that the later performs much better in terms of power, timing and is area efficient. The 6T and 4T load less memory cell is further converted for multiport operation and simulated for various performance parameters such as area, power and delay and compared.","PeriodicalId":443239,"journal":{"name":"2011 Fourth International Conference on Emerging Trends in Engineering & Technology","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123734244","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}

The fixed WFs are replaced by changeable WFs. The challenges faced by a workflow at the time of execution due to its flexible nature are focus of this paper. Flexibility is the capability of workflow process to execute on the basis of a loosely, or partially specified model, where the full specification of the model is made at runtime, and may be unique to each instance or at each sub-workflow level. This flexibility introduces different challenges during the course of execution.

Weight reduction can be achieved primarily by the introduction of better material, design optimization and better manufacturing processes. The achievement of weight reduction with adequate improvement of mechanical properties has made composite a very good replacement material for conventional steel. Selection of material is based on cost and strength of material. The composite materials have more elastic strain energy storage capacity and high strength to weight ratio as compared with those of steel, so multi-leaf steel springs are being replaced by mono-leaf composite springs. The paper gives the brief look on the suitability of composite leaf spring on vehicles and their advantages. The objective of the present work is design, analysis and fabrication of mono composite leaf spring. The design constraints are stress and deflections. The material selected is glass fibre reinforced plastic (GFRP) and the epoxy resin can be used which is more economical to reduce total cost of composite leaf spring with similar mechanical and geometrical properties to the multileaf spring. The composite leaf spring is fabricated by hand lay-up technique and tested. The testing was performed experimentally with the help of UTM and by (FEA) using ANSYS software showing stresses and deflections were verified with analytical and experimental results. Compared to the steel spring, the composite spring has stresses that are much lower, the spring weight is nearly 74% lower.","PeriodicalId":443239,"journal":{"name":"2011 Fourth International Conference on Emerging Trends in Engineering & Technology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124845964","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}

Parallel Concatenation of LDPC Codes with Two Sets of Source Bits 具有两组源位的LDPC码的并行连接

Soyjaudah","doi":"10.1109/ICETET.2011.46","DOIUrl":"https://doi.org/10.1109/ICETET.2011.46","url":null,"abstract":"Conventional attempts at using parallel concatenation for LDPC codes have not been widely successful. Interestingly, existing schemes do not rely on the concatenating architecture, but rather on the complementary profile of two carefully selected component codes. Each code individually drive the decoding process over the signal-to-noise ratio range over which it excels. In this work however, a concatenating scheme is proposed that is not limited by specific choices of component codes. In addition, the scheme also departs from conventional turbo style settings by transmitting two sets of source bits over the channel, instead of just one. At the receiving side then, two decoders are set up and share extrinsic information. The key difference however with the conventional turbo style, is that the channel information (being independent for both decoders) is not removed when computing the extrinsic information. As signal-to-noise ratio increases, the associated impact of this modification results in a valuable performance gain.","PeriodicalId":443239,"journal":{"name":"2011 Fourth International Conference on Emerging Trends in Engineering & Technology","volume":"39 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123283591","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}

In this paper we propose two new techniques to obtain the control code for a mobile robot through \"programming by demonstration\". Initially, a robot is controlled by a human operator who manually guides the robot through a desired path this is called teaching phase, and then the robot will navigate autonomously with taught information this is called execution phase. In contrast to traditional robot programming techniques, these methods does not require specialized technical or programming skills, but translates demonstrated behavior immediately into executable code. This has obvious implications for the widespread use of personal service robots.","PeriodicalId":443239,"journal":{"name":"2011 Fourth International Conference on Emerging Trends in Engineering & Technology","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122060610","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}
