Differential Elasticity of Substitution in the Indian Industries

The paper specifically focuses on the impact of reforms to see whether there has been any shift in the differential elasticity of substitution between labour and capital in Indian industry. The main conclusion of the paper is that there are differential elasticities of substitution between labour and capital, both pre and post economic reform period in India, hence substitution possibilities are relatively skewed in favour of labour during post economic reform in the Indian industry., CES Production Function, Differential Elasticity, Economic Reforms

High speed train communications systems using free space optics

In this work, we propose a broad-band free space optical (FSO) wireless communications system for high-speed trains. The system consists of optical transceivers positioned outside the train and along the railway track. The train receivers are in the coverage area of base stations positioned along the railway track to ensure continuous link availability. In this paper, we present modelling of two cases for over-ground and underground train systems before embarking to practically implement the system in our research laboratory. Also discussed is the protocol for the data distribution along the track as well as the initial experimental demonstration of the proposed link
