Abstract -
IPv6 has extended features with a host of advantages when compared to IPv4 which could be capitalized to leverage on today’s communication needs. Apart from its advantages, IPv6 header size has increased to twice the size of a typical IPv4 header. The paper points out the need of IPv6 addressing in IPv4 network and proposes a new addressing mechanism with a clear implementation procedure, while not restricting any IPv6 mobile node to roam only in IPv6 based networks. The main focus of the proposal is to permit an IPv6 mobile node to roam also into IPv4 based network and get serviced besides roaming in IPv6 based network.

Abstract -
Supply chain management (SCM) is concerned with the efficient integration of suppliers, factories, distributors, warehouses, and stores so that merchandise is produced and distributed in the right quantities to the right locations at the right time in order to minimize total system cost and satisfy customer service requirements. In SCM, what is required is how to improve the performance. Supply chains, in an attempt to be more competitive, are adopting new management paradigms. Among these paradigms, there are five that deserve particular mention because of their importance to better SC performance: lean, agile, resilient, green and talentship (LARGT) paradigms. Performance measurement is crucial to better SCM. The lack of appropriate metrics for these measurements could be the main reason responsible for the following failure breakdowns in the supply chains: (1) inability to meet customer satisfaction; (2) suboptimization of firms’ performance; (3) loss of opportunities to outperform the competition; and (4) creation of conflicts within the supply chain. The simultaneous integration of LARGT paradigms in SCM may help supply chains to become more efficient and streamlined, and also more sustainable. In this paper an extensive overview on supply chain paradigms (LARGT) and the performance indicators associated with each paradigm to improve supply chain performance. A model was implemented using java language and MySQL showing the effect of these performance indicators to improve the performance. The simulated results evaluates the suppliers and distributors performance and enables us to choose the best of them. The firm was evaluated to improve its performance continuously. The results of this paper is very useful and promising.

Abstract -
Advances in the electrical and electronics communication technologies led to large scale development and research in area of Wireless Sensor Network. Wireless Sensor network have numerous applications in recent scenarios. WSN have a large number of constrained attached to them such as less processing capability, low memory, limited energy resources and security issues. WSN generally deployed in natural environment hence a large number of security issues are there. Here we look at the basic Sensor network application classes and hybrid network of wireless sensor network.

Abstract -
Automatic image registration is a vital yet challenging task, particularly for remote sensing images. A fully automatic registration approach which is accurate, robust, and fast is required. The registration process is divided into six main steps: feature detection, feature extraction, feature matching, outlier detection and removal, transform model estimation and resampling. In the feature detection, keypoints (PCA-SIFT), blob (SURF), region (MSER) features are detected. The features are then matched to produce point correspondences. The alignment process uses the RANSAC algorithm to estimate an outlier free transformation using point correspondences. The target image is transformed by using transformation function, which results in automatic image registration. Mutual information is used for fine tuning registration. In this thesis, feature descriptors used are SURF (Speeded Up Robust Features), MSER (Maximally Stable Extremal Regions) and PCA-SIFT. They are invariant to zoom, noise, scale, rotation and illumination, hence very useful. The analysis is conducted for various image transformations such as image rotation, scaling and change in illumination. For all these transformations, various quality checking parameters such as recall and RMSE error are evaluated to analyse the performance of registration. In the registration of multiview images, the affine transformation model applied is not suitable. So a more appropriate transformation models such as thin-plate spline is subtitled the affine model in the proposed work.
