Abstract:

Data encryption is widely used to ensure security in open networks such as the internet. Different techniques should be used to protect confidential image data from unauthorized access. Most of the available encryption algorithms are used for text data. However, due to large data size and real time constrains, algorithms that are good for textual data may not be suitable for multimedia data. Visual Cryptography is a simple, fast, visual cryptography technique, to provide privacy protection when transmitting sensitive data between offices. Visual cryptography takes a financial document represented as a bit map file, and expands it into two or more encoded file shares. These shares can be transferred to the recipients via electronic mail or electronic file transfer process. In order to recover the original document, the recipient needs to have only the desired subset of the shares and the decoding program. The idea of the visual cryptography model proposed is to split a secret image into two random shares. The secret image can be reconstructed by stacking the two shares.

Abstract:

Land use and land cover usually concludes to some type of development with impacts such as loss of agricultural land, open space, and ecologically sensitive habitats. Present paper effectively demonstrates the efficacy of remote sensing and GIS to perceive and record the land use and land cover of the area and its changes through time. Information on land use/land cover and potentials for their optimal use is essential for the selection, planning and execution of land use schemes to meet the growing demands for basic individual needs and welfare. Remote Sensing (RS) and Geographic Information System (GIS) technology are currently the latest tools for monitoring land use changes. In the present paper Resourcesat-2 satellite data (LISS–III) was used for different seasons for the year 2005-06 to 2011- 2012 to perceive the changes of Jind district. Satellite data are found to be useful in mapping and quantifying the changes of land use and land cover of the study area. This study shows that built-up area has increased during the period of 2005-06 to 2011- 12. The present paper is an attempt to analyze the changes that have taken place in land use pattern in Jind district from 2005-06 to 2011-12. The study reveals that marginal changes have occurred in all land use categories except proportion of area under agriculture area which has drastically declined from 93.42 percent in 2005-06 to 92.63 percent in 2011-12. Major increase was observed in built-up area from 2005-06 to 2011-12.

Abstract:

In java the classes Pattern and Matcher are useful for solving DNA sequencing and Motif Finding Problems. Pattern is a compiled representation of a regular expression. Matcher is an engine that performs match operations on a character sequence like DNA sequence by interpreting a Pattern. The Bioinformatics problems like DNA sequencing, DNA Mapping, Predicting Genes, Comparing Genes and Genome Rearrangements need enormous support from programming language constructs for searching billions of DNA chemical nucleotide bases (A,T,G,C). In this regard, System defined Java classes from java.util.regex java package will play an important role. Their capabilities will be analyzed in this research paper by doing dry lab experiments.

Abstract:

Due to rapid advancement in information technology, digital revolution creates a new era & scope in smart based e-devices. New portable and electronic devices take place of old text books. In this study we introduced some key questions with novel emerging e-Smart based knowledge management environment. Smart based learning simply means that learning and teaching by electronic devices. Our study also established some key findings especially in human quality based development (HQBD) such as thinking ability, living slandered, human value, future based life planning etc. We also observe during our study, living slandered are significantly improve and also this things create a new space to eradicate the poverty alleviation in developing countries. We develop a system based on Service Oriented Architecture (SOA), key features of this system one can take online examination, evaluation, offline study and also enable us to arrange online and offline examination module for technology poorer country specially in third world countries. During study we also focus & delineate to ask people about what are the changes they observe or found when they adopt new way of learning & knowledge based management system.

Abstract:

Automatic summarization is the process of reducing a text document with a computer program in order to create a summary that retains the most important points of the original document. With the increasing popularity of Internet and the variety of information obtaining technologies, the amount of quickly growing information has gone beyond our imaginations. Many techniques were presented to help users to find the desired information from large data set quickly and accurately, automatic summarization is an effective approach. Text Summarization methods can be classified into extractive and abstractive summarization. Extractive summaries are created by reusing portions like words, sentences, etc. of the input text exactly. In abstractive summarization, information from the source text is rephrased. Special attention is devoted to automatic evaluation of summarization systems, as future research on summarization is strongly dependent on progress in this area.
