Abstract: Replication strategy is mostly useful for replicating the mobile user's profile at selected locations where some callers have higher calling rate. It plays important role in personal communication services (PCS) in order to reduce call setup time and increase the QoS. We have proposed a novel and innovative replication tree which is based on the Huffman tree and there is interrelationship between the replicated sites based on their effective replication probability. In the proposed scheme, the total network traffic statistic data of a mobile user is considered to define effective replication probability.

Abstract: Over the past few decades we have seen tremendous growth in the field of Magnetic Resonance Imaging (MRI) Brain image processing. It requires various steps to ensure that the desired result is obtained. One of the constituent processes for the basic study of the brain parts is the edge detection, which is the initial module for all other post processing procedures. These edges characterize the abnormalities existing in the human brain. Hence it should be done with utmost care for obtaining worthy result. In this paper, a new approach to MRI brain edge detection problem is presented. It consists of two stages. First the original MRI image is passed through image segmentation block and in the second stage edge detection algorithm is applied to the segmented image. Image segmentation is done using Genetic algorithm incorporating Fuzzy C means clustering (GAFCM) and Canny edge detection Algorithm is used for edge detection. Although this approach has high computational complexity it greatl
