Acetoxylation of o, m Cresol by Electrochemical Process at Graphite Electrode
Abstract: Electrochemical processes remain unique because of the nature of specific products formed and their mode of formation in which current is a reactive input in place of redox reagents. The high yields of the products can be obtained by designing and optimizing the electrolysis. The ordinary chemical procedures are multi-staged and may result poor yields. Therefore the best way for minimizing the pollution is transformation of conventional chemical processes to …

A Graph Theoretic Approach to quantify the Conflict of Traffic Streams in a Traffic Intersection
Abstract: A traffic intersection can be modelled by a graph by considering the streams as vertices and assigning an edge based on the mutually non-conflict streams. In this paper we propose a spectral approach to arrange the steams in order of their conflict and hence determine the most conflicted stream in a traffic intersection.
