Hierarchical Data Structures for Accessing Spatial Data

Abstract: Spatial data is data related to space .In various application fields like GIS, multimedia information systems, etc., there is a need to store and manage these data. Some data structures used for the spatial access methods are R tree and its extensions where objects could be approximated by their minimum bounding rectangles and Quad tree based structures where space is subdivided according to certain rules. Also another structure KD Tree is used for organizing points in a k dimensional space. In this paper we have described an algorithm for insertion of points in a Quad tree based structure, known as PR Quad Tree. Another data structure called K-D Tree is also described and the insertion procedure is defined. Then the comparison between the two structures is drawn.

Energy dissipation in wave propagation in general relativistic plasma

Abstract: Based on a recent communication by the present authors the question of energy dissipation in magneto hydrodynamical waves in an inflating background in general relativity is examined. It is found that the expanding background introduces a sort of dragging force on the propagating wave such that unlike the Newtonnian case energy gets dissipated as it progresses. This loss in energy having no special relativistic analogue is, however, not mechanical in nature as in elastic wave. It is also found that the energy loss is model dependent and also depends on the number of dimensions.

Water Management for Checking the Water Usage and Preventing Wastage

Abstract: Most of the Indian homes are still dependent on the water from tube wells, bore wells so they are desperate to save every drop of water. The water scarcity in India has reached an alarming state. It will remain a problem until and unless people, as responsible citizens do their bit. It may not be possible to solve the problem but one can always save water as much as one can. This project focuses on creating a device that would detect gaps/holes in the pipes used to transport water to each apartment in a building. In a huge network of pipelines, it becomes impossible to detect small leaks. If the device can detect any kind of leaks in the pipelines through total monitoring, then taking the necessary actions quickly will help to save a lot of water. Also it will allow checking the amount of water usage. The total management system consists of various parts assembled together.

Stiffened Hypar Shell with Cutout

Abstract: Free vibration characteristics of stiffened composite hypar shell (hyperbolic paraboloidal shells bounded by straight edges) in the presence of cutout are considered following a generalized finite element formulation using eight-noded curved quadratic isoparametric element for shell with a three-noded beam element for stiffener. The size of the cutouts and their positions with respect to the shell centre for different edge constraints are varied to obtain the results in the form of figures and tables. The results are analysed to achieve guidelines for the selection of optimum size and position of the cutout with respect to shell centre considering different practical constraints.

Visual Cryptography

Abstract: In this paper, we propose a Visual Cryptographic system which can be used to hide the original image information from an intruder or an unwanted user. The images can be in any standard format. The encrypted image is sent to the destination through the network and then the image is decrypted. We have used Symmetric-key cryptography.
