An improved simulated annealing algorithm for standard cell placement

Simulated annealing is a general purpose Monte Carlo optimization technique that was applied to the problem of placing standard logic cells in a VLSI ship so that the total interconnection wire length is minimized. An improved standard cell placement algorithm that takes advantage of the performance enhancements that appear to come from parallelizing the uniprocessor simulated annealing algorithm is presented. An outline of this algorithm is given

A parallel algorithm for global routing

A Parallel Hierarchical algorithm for Global Routing (PHIGURE) is presented. The router is based on the work of Burstein and Pelavin, but has many extensions for general global routing and parallel execution. Main features of the algorithm include structured hierarchical decomposition into separate independent tasks which are suitable for parallel execution and adaptive simplex solution for adding feedthroughs and adjusting channel heights for row-based layout. Alternative decomposition methods and the various levels of parallelism available in the algorithm are examined closely. The algorithm is described and results are presented for a shared-memory multiprocessor implementation

Online Resume Mart

The main objective of the online resume is to design and develop a web service which is a place for Job Seekers and Job Providers to meet. The data base is used to collect all the details of the job seeker and provider. Online resume collects multiple resumes from the Job seeker and the job provider is provided with the data required as per need of the company

Describing, assessing and embedding flexibility in system architectures with application to wireless terrestrial networks and handset processors

Thesis (S.M.)--Massachusetts Institute of Technology, System Design & Management Program, June 2004."January 2004."Includes bibliographical references (p. 165-168).This thesis presents a framework that can be used to identify the flexibility attributes and determine the value of embedding flexibility in system architectures, from the context of network based wireless applications and wireless handset processors Flexibility is first defined and the three dimensions of flexibility - performance, capacity and functionality are explored. This analysis is used to formulate a general model of the dimensions of flexibility. The analysis to determine the value of embedding flexibility is then done using the example of a flexible handset processor. The Black-Scholes model and the Binomial model are presented as methods for computing the economics of financial options. These methods are then applied to computing the value of flexibility options. In order to determine the value of the underlying asset, which is one of the terms needed for the valuation of flexibility, two approaches are presented: conjoint analysis and concept engineering. The bounds of time to expiation are explored. The cost of embedding flexibility is then assessed. Finally, a few methods are proposed for determining the optimal flexibility design vector and implementing a portfolio of real option based flexibility strategy.by Prithviraj Banerjee.S.M

Molecular Interplay between Vitamin D and Immunity can Aid Antitubercular Treatment Vitamin D in Immunomodulation of TB

Tuberculosis (TB) causes maximum mortality and morbidity worldwide. 25 per cent of the global population harbour Mycobacterium tuberculosis (Mtb) and therefore are at risk of developing active disease. Of late, the disseminated diseases of TB are on the increase. Nearly one-third of all TB infections can be classified as extrapulmonary-TB (EPTB). TB can spread to the bone, brain, intestine, peritoneum, genitourinary system, and female genital sites leading to problems of conception. Therefore undoubtedly, TB has turned out to be a tremendous public health problem globally. The emergence of drug-resistant bacteria calls for new anti-tuberculous drugs to enhance response to antimicrobial therapy for active TB. However, discoveries of very effective anti-TB new medicines have not materialised yet. Thus, nutritional anti-TB intervention is highly important. In the pre-antibiotic era, Vitamin D was used for the treatment of TB. Its active component 1,25-dihydroxy-vitamin D3 was shown to display anti-TB activity in vitro. Vitamin D deficient humans display greater susceptibility to TB. Vitamin D deficiency induces worse disease progression in TB cases as observed in many clinical trials. The efficacy of the addition of vitamin D supplements in TB treatment has also been estimated. Thus, by now, the role of vitamin D in TB prevention and treatment is well established. Knowledge of the molecular mechanism of vitamin D is crucially vital for new anti-TB drug design. This review article discusses the recent advancement regarding the molecular mechanism of vitamin D-related anti-TB action. Further elucidation of this area may help novel anti-TB drug development
