Software Production, Human Capital and Endogenous Growth: Theoretical Analysis and Empirical Evidence from India

Propelled by the rise of a vibrant software industry the Indian economy has demonstrated rapid growth since the 1990s. A novel three-sector endogenous growth model that encapsulates the salient features of an information technology oriented economy is developed. The dynamic optimization problem leads to a balanced growth path equilibrium characterized by output, physical capital, software assets, human capital and consumption growing at a uniform rate. Major implications of the model are reflected in empirical evidence from the growth trajectories of Indian states. The human capital production apparatus has a significant impact on economic growth. This has critical policy implications.endogenous growth, India, information technology, human capital, software

A Distributed Query Processing Engine

Wireless sensor networks (WSNs) are formed of tiny, highly energy-constrained sensor nodes that are equipped with wireless transceivers. They may be mobile and are usually deployed in large numbers in unfamiliar environments. The nodes communicate with one another by autonomously creating ad-hoc networks which are subsequently used to gather sensor data. WSNs also process the data within the network itself and only forward the result to the requesting node. This is referred to as in-network data aggregation and results in the substantial reduction of the amount of data that needs to be transmitted by any single node in the network. In this paper we present a framework for a distributed query processing engine (DQPE) which would allow sensor nodes to examine incoming queries and autonomously perform query optimisation using information available locally. Such qualities make a WSN the perfect tool to carryout environmental\ud monitoring in future planetary exploration missions in a reliable and cost effective manner
