In VLSI physical design automation, channel routing is a fundamental problem but reducing the total wire length for interconnecting the nets of different circuit blocks is one of the most challenging requirements to enhance the performance of a chip to be designed. Reducing the total wire length for interconnection not only minimizes the cost of the physical wire segments required, but also reduces the amount of occupied area for interconnection, signal propagation delays, electrical hazards, power consumption, heat generation, and over all the parasitics present in a circuit. Thus it has a direct impact on daily life and environment. Channel routing problem for wire length minimization is an NP-hard problem. Hence as a part of developing an alternative, we modify the existing graph theoretic framework Track_Assignment_Heuristic (TAH) to reduce the total (vertical) wire length. In this paper we propose an efficient polynomial time graph based parallel algorithm to reduce the total wire length without radically increasing of required area for interconnection in the reserved two-layer no-dogleg Manhattan channel routing model. The performance and efficiency of our algorithm is highly encouraging for different well-known benchmarks channels.","PeriodicalId":399616,"journal":{"name":"2012 5th International Conference on Computers and Devices for Communication (CODEC)","volume":"330 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115968811","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 answer however turned out to be `indeed yes'. There emerged a resurgence of interest to design and fabricate exotic class of specialty fibers, in which transmission losses of the material would not be a limiting factor while nonlinearity and dispersion characteristics could be conveniently tailored. Research targeted towards such fiber designs led to the emergence of a new class of fibers, broadly referred to as microstructured optical fibers, which are characterized by wavelength-scale refractive index features across its physical cross-section resulting in photonic bandgaps when appropriately designed. This talk would focus on our research in recent years on designs of a variety of such photonic bandgap fibers for a variety of applications such as dispersion compensating fibers, metro fibers, supercontinuum (SC) light generating fibers, parabolic pulse generating fibers for fiber lasers, almost non-dispersive propagation of ultra-short light pulses for biomedical applications, large mode area soft-glass based fibers for mid-infrared wavelengths, and chalcogenide fiber-based mid-ir fibers as light source, SC generator, and for high power delivery.","PeriodicalId":399616,"journal":{"name":"2012 5th International Conference on Computers and Devices for Communication (CODEC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127175859","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 are in use for identification of protein coding regions in genes. Application of Fourier technique is one of the most popular methods of gene prediction, in which prediction algorithm is based on period-3 property of DNA where it exhibits a prominent peak in coding region. Spectrum estimation by Fourier method generates various harmonics, generally known as 1/f noise along with sharp peaks, which may lead to false prediction of coding regions. Researchers used various parametric and non-parametric filters to tackle this problem and improve the accuracy of prediction. Performance of anti-notch filter with cascaded lattice structure on one hand and harmonic suppressor with comb filter on the other hand have been compared here for identification of coding regions of C-elegan F56F11.4a chromosome. The authors have analyzed the performance in terms of standard deviation and signal-to-noise ratio. A Matlab simulink environment has been used for filter realization and performance analysis.","PeriodicalId":399616,"journal":{"name":"2012 5th International Conference on Computers and Devices for Communication (CODEC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114788641","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}
