Advances in data storage and image acquisition technologies have enabled the creation of large image database. In order to deal with these data, it is necessary to develop method to efficiently manage these collections In these systems, image processing algorithms using different method for feature extraction like texture and which method provides better(More)
— In wireless sensor-actor networks, sensors probe their surroundings and forward their data to actor nodes. Actors collaboratively respond to achieve predefined application mission. Since actors have to coordinate their operation, it is necessary to maintain a strongly connected network topology at all times. Moreover, the length of the inter-actor(More)

In this paper, a comparative analysis of various space time codes that are used in multiple input multiple output (MIMO) systems to achieve high data rate at high quality of service is presented. MIMO systems are analyzed under fading environment and their performance in terms of diversity gain, data rate, detection complexity, size of signal(More)
This paper covers an extensive detailed analysis about the use of cooperative communication in cognitive radio especially the underlay technique. Authors have also tried to explain the effect of using multiple relay instead of single relay on outage probability. Asymptotic analysis of the proposed system model is also derived and results are compared. This(More)
In this paper authors have tried to explain single relay model of cooperative communication with underlay spectrum sharing mode with two different possibilities of transmission i.e. with and without diversity along with their asymptotic analysis. Authors have tried to explain both transmission in comparison form through the graphical results and verified by(More)
— this paper is about to make a contribution in the field of fuzzy query processing. We are mainly interested in query mechanism for evaluation of fuzzy quantified queries on the relational database. We restrict our work to fuzzy quantified sentences of form S1, involving linguistic quantification of fuzzy conditions over crisp sets. We proposed a new(More)
In this project we present Trinity Tree Algorithm comparison with Back Propagation Algorithm. Among these the trinity tree algorithm is an unsupervised data extraction and Backpropagation algorithm is a supervised data extraction. Data mining is a growing topic of interest in latest Engineering subject as it has help in the research area to extract(More)
