A New Proposed Cost Model for List Accessing Problem using Buffering

There are many existing well known cost models for the list accessing problem. The standard cost model developed by Sleator and Tarjan is most widely used. In this paper, we have made a comprehensive study of the existing cost models and proposed a new cost model for the list accessing problem. In our proposed cost model, for calculating the processing cost of request sequence using a singly linked list, we consider the access cost, matching cost and replacement cost. The cost of processing a request sequence is the sum of access cost, matching cost and replacement cost. We have proposed a novel method for processing the request sequence which does not consider the rearrangement of the list and uses the concept of buffering, matching, look ahead and flag bit.Comment: 05 Pages, 2 figure

Deposition of SiC Derived from Desert Sand and Wood Charcoal by Plasma Processing

The basic aim of my project was to find a cheaper source of silicon carbide to use as coating on metal plates to increase their wear resistant properties. Silicon carbide has very high wear resistant properties so is ideal for coating on metal surface using plasma processing. The plasma process uses temperature of the order of 5000k and higher. So our target was to utilize this high temperature to fire a reaction between silica(sio2) and carbon to form silicon carbide. For silica we used sand and for carbon we used wood charcoal. Though the reaction was theoretically possible but at such high temperature we couldn’t be sure whether the chemical kinetics would follow the expected path. There was the risk of carbon behaving as reducing agent and converting alumina present in sand to aluminium.So we decided to perform the experiment in Plasma Laboratory at the Laser and Plasma Technology Division, BARC so that the project does not just remain a theory
