The proposed approach captures the design specification of a class of circuits into a language independent high level library of models. Taking the user input, and the domain knowledge from the specification, and by parsing the library of models, the model generator automatically generates the behavioral models in different languages. In this work, the behavioral models are developed in Verilog-A and SPICE languages, which are often used in industrial applications and are also structurally different. The methodology is explained with a synthetic example of programmable gain amplifier with automatic gain control circuit.","PeriodicalId":262830,"journal":{"name":"2010 IEEE Students Technology Symposium (TechSym)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123084474","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}

This mega project generated huge amount of Data and Information. The Enormous amount of data generated through whole-genome sequencing efforts, microarray technologies, and mapping of single nucleotide polymorphisms (SNPs), proteomics, and many other efforts, have created chasm of knowledge for most traditionally trained biologists on how to interpret and utilize wealth of information. The storage and management of the data and its processing posed challenges to the information scientists too, which resulted in the birth of bioinformatics. The discipline, Bioinformatics is drawing concepts from various subject areas such as biological sciences, computer science, genetics, mathematics and statistics. Various related resources also emerged in the form of published literature, specialized centers for bioinformatics, organism specific databases and software tools to analyze data. Database driven technology emerged as one of the solution to maintain and sustain the information. Bioinformatics being a novice subject field and it utilizes multidimensional approach for analysis of data. There are various problems related to generation, communication and interaction of biological information due to heterogeneity. The Users of bioinformatics information often find it a challenge to get awareness and access to the relevant information. Information literacy, creation of databases, consolidation of information resources and presenting them in helpful manner for coherent access are some of solutions for enhanced access. This paper is deals with design and development of a single tool for providing access to variety of resources in bioinformatics.","PeriodicalId":262830,"journal":{"name":"2010 IEEE Students Technology Symposium (TechSym)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123641593","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 resonators exhibiting metamaterial characteristics are split ring resonator (SRR), spiral resonator (SR), omega and fractal resonator. This paper presents a new type of resonator called as an open split ring resonator (OSRR) exhibiting negative permeability. OSRR is modified structure of split ring resonator (SRR). A metamaterial cell is constructed by the OSRR and wire arrangement. The complex permittivity and permeability of the cell is retrieved from the scattering parameters. As compared to the split ring resonator, open split ring resonator is smaller in size for the same resonance frequency and hence this leads to a size miniaturization in various metamaterial applications.","PeriodicalId":262830,"journal":{"name":"2010 IEEE Students Technology Symposium (TechSym)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125775298","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 has been extensively exploited in biomaterials research due to its easy tailorable structure and function. Chitosan fibers are being produced through wet-spinning route for different purposes. But, chitosan fibers produced in conventional alkaline bath generally suffers from quick dissolution in acidic media and high degradation rate in vivo. Crosslinking of the fibers with chemical agents is usually preferred to avoid that problem of instability. The crosslinking agents are highly toxic in nature and not suitable for biomedical use. Crosslinking of chitosan fibers with any non-toxic agent could make it better biocompatible and may find potential biomedical application. Present study focuses on production of chitosan-tripolyphosphate fibers through wetspinning technique. STPP was used as an in situ coagulant cum crosslinking agent for chitosan fibers. The fibers were produced by injecting homogeneous chitosan solution through a spinneret into sodium tripolyphosphate (STPP) coagulation bath. Viscosity of the chitosan solutions was measured for evaluation of flow behavior at different shear rate. FTIR analysis revealed presence of ionic cross-linking between tripolyphosphates (TPP) and chitosan molecules in chitosan-TPP fibers. Swelling behavior and water retention capacity of the chitosan-TPP fibers were also evaluated. Scanning electron micrographs showed fine chitosan fibers with diameters ∼ 40 µm. These chitosan-TPP fibers may have potential biomedical applications due to their non-toxic in nature and enhanced stability.","PeriodicalId":262830,"journal":{"name":"2010 IEEE Students Technology Symposium (TechSym)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131512455","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 mobile environment, the major issues are background noise, coding and channel impairments. Most of the existing works deal only with the recognition of noisy speech, but in this paper, we have explored about the recognition of speech under noisy coded condition, and it is shown that the performance of recognition is improved by spectral processing techniques. Finally, in this paper, we have shown that speech coding does not significantly affect on the performance of digit recognition. Also, we have compared the results of spectral methods used here for preprocessing, and concluded that Minimum Mean Square Error (MMSE) [1] method produces better result than spectral subtraction method [2].","PeriodicalId":262830,"journal":{"name":"2010 IEEE Students Technology Symposium (TechSym)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131881123","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}

Achieved input common mode range (ICMR) is 71.43 – 700 mV. DC electrode offset cancellation circuit is realized to remove DC electrode offset along with the low frequency noise. The IA can withstand a high DC electrode offset of ±18 mV. It also has a wide input dynamic range of ±1 µV to ±1 mV. The voltage gain is around 38 dB. It consumes 110 µW power with a supply voltage of 1 V. A high common mode rejection ratio (CMRR) of 80 dB is achieved. The integrated input referred noise is 1.64 µVrms (0.1 Hz – 150 Hz).
