Role Of Information Technology In Integrating Biological Databases Into Metabases- A Review
Life science researchers are experiencing a “data explosion” due to vast amounts of raw data being produced genomic, proteomic, and structure predicting experimentation. This exponential growth curve is expected to continue. These piles of data are kept in different databases scattered across the diverse industries, different universities and research institutes throughout the world. There is a dire need for the creation of intelligent database of these databases to query, collect, link, merge, analyze and give biological sense to these different data to tackle more and more intricate and challenging scientific problems. An imperative resource for finding biological databases is a special annual issue of the journal Nucleic Acids Research (NAR).which is freely available and categorizes many of the publicly available on line databases related to biology and bioinformatics. Although a huge variety of database are available online, PubMed maintained by the National Center for Biotechnology Information (NCBI); Ensembl maintained by the European Bioinformatics Institute (EBI) and the Wellcome Trust; the UCSC Genome Browser a human, mouse and rat genome browser maintained by David Haussler’s group at the University of California at Santa Cruz; FlyBase maintained by the FlyBase Consortium; WormBas, and the Gene Ontology (GO) database exemplify some of the major biological databases. Many researchers are not aware of their availability and consequently these databases were not effectively utilized. A better solution would to generate a database of database which contains a plethora of information of various biological databases, maintaining the scientific and political independence of the databases, but allowing the information that they contain to be easily integrated to enable cross-database queries.This study deals with the features of four major metabases of biological databases – DBD (database of biological databases) http://www.biodbs.info/, DOD – Database of Databases (http://www.progenebio.in /DoD/DoD.htm), MetaBase - The Database of Biological Database (http://biodatabase.org) and DBcat (http://www.infobiogen.fr/services/dbcat). ...

E-Security: Proposed Algorithm Of Authenticity Of Digital Signature
The increasing use of digital signature in electronic documents poses special challenges in verifying authenticity, because digital technology makes such documents easy to alter or copy, leading to multiple non-identical versions that can be used in unauthorized or illegitimate ways. To help meet the challenge of the digital age but also provide the assurance that an electronic document has not been altered. A digital signature, viewed through authenticity, verifies documents, at no cost to the customer. [12] Everyone is used to dealing with an original document, or an authenticated copy of the original document, but is in difficulties when the concept of ‘original’ proves to be elusive in respect of a digital signature, whatever form it takes. [8] Data and information security becomes more and more important in digital signature which uses a public high-speed wide area network. Generally, E-security is characterized in terms of privacy, authenticity and integrity of digital data. [14]Authentication is concerned for both information providers and information users thought the process. [5]This paper proposed an algorithm with flowchart of authenticity of digital signature that gives us generalization to check security and authentication of digital signature effectively. ...

Scaling K-Mode Algorithm For Clustering Large Categorical Dataset And Its Performance Analysis
Scalable data mining algorithms have become crucial to efficiently support KDD processes on large datasets. The k-mode is one of the partitioning algorithms used for the purpose of clustering. We show that basic k-mode algorithm is very much time consuming for large dataset. Instead we present the advanced algorithm which performs much better than known algorithm. In addition to presenting detailed experimental results for advanced k-mode algorithm, we also conduct an experimental study with real life data sets to demonstrate the effectiveness of our technique. We address the task of scaling up k-modes based algorithm through the utilization of memoization technique. Experimental results based on several datasets, including synthetic and real data, show that the proposed algorithm may reduce the number of distance calculations by a factor of more than a thousand times when compared to existing algorithms while producing clusters of comparable quality. ...

Recognition of Face Using Artificial Neural Network
Face recognition is done naturally by humans. However, developing a computer algorithm to do the same thing is difficult. Assume for the moment we start with images, and we want to distinguish between images of different people. One class of methods presupposes the existence of certain features in the image, i.e. eyes, nose, mouth, hair, and an algorithm is devised to find and characterize these features. FACE recognition is an important research problem spanning numerous fields and disciplines. This because face recognition, in additional to having numerous practical applications such as bankcard identification, access control, Mug shots searching, security monitoring, and surveillance system, is a fundamental human behavior that is essential for effective communications and interactions among people. ...

BER Study of OFDM With Coding And Without Coding Transmission On Nakagami-M Fading Channel
High bit error rates of the wireless communication system require employing forward error correction (FEC) methods on the data transferred to reducing the error in transmission. In this paper, the performance of OFDM- BPSK,-QPSK and -QAM system by using forward error correcting codes as concatenated codes schemes that are used to encode the data stream in wireless communications Nakagami-m fading channel has been reported here . Our approach is based on decomposition of Nakagami random variable into orthogonal random variables with Gaussian distribution envelopes. Results have been presented by using optimum value of m based on BER and SNR We present OFDM for wireless communications .We address basic OFDM and related modulations, as well as techniques to improve the performance of OFDM for wireless communications (OFDM). we performed simulations to find out the best BER performance using RS-CC concatenated codes. By concatenating two different codes we can get the effect of improving the total BER due to benefits of RS codes correcting burst errors while convolutional codes are good for correcting random errors that are caused due to a noisy channel. ...
