R. F. pollution has been recognized as health hazard in India in the prevailing circumstances. There is lot of hue and cry against cellular towers installed in residential area. Recently high court in India has issued an order not to install towers in residential areas. For meeting the exponential demand of cellular communication in India this w ill be a set back for future growth. An appropr i...

A geothermal power plant multiple simulator for operators training is presented. The simulator is designed to be installed in a wireless local area network and has a capacity to train one to six operators simultaneously, each one with an independent simulation session. The sessions must be supervised only by one instructor. The main parts of this multiple simulator are: instructor and operator’...

Terrestrial Digital Multimedia Broadcasting (TDMB) is one popular broadcasting standard that enable digital television transmissions to hand held receivers and cooperative system take advantage of the broadcast nature of wireless channels, uses relay stations as virtual antennas. Relay stations are an attractive solution to penetrate the wireless system with lower transmitting power at the Base...

Ad-hoc networks are an emerging networking technology, in which the nodes form a network with no fixed infrastructure: each node forwards messages to the others by using the wireless links induced by their power levels. Generally, energy-efficient protocols heavily rely on cooperation. In this paper, we analyze from a game-theoretic point of view the problem of performing a broadcast operation ...

Abstract: The rollout of electric vehicles substantially changes the requirements for current power grid infrastructures. The high power demand of fast recharge stations in combination with a high risk of simultaneity leads to the necessity of extended ICT integration into the energy distribution process. This paper describes ongoing research on a simulation framework for modeling the communica...

Power can be generated from the pressure energy of natural gas along its supply chain at various pressure reduction points by using turbo-expanders. This technology is being applied in different countries around the world. This paper attempts to asses the potential of using this technology for Bangladesh. A number of producing wells and pressure reduction stations are investigated. It is found ...

The severe accident that broke out at Fukushima Dai-ichi nuclear power stations on March 11, 2011, caused seemingly infinite damage to the daily life of residents. Serious and wide-spread contamination of the environment occurred due to radioactive materials discharged from nuclear power stations (NPSs). At the same time, many issues were highlighted concerning countermeasures to severe nuclear...

This study concentrates mainly on the 12-year time trends of annual average ion concentrations in bulk precipitation from 10 Estonian monitoring stations. Trends revealed by the nonparametric Mann-Kendall test mostly show a statistically significant decline and, according to the order of ion decline per year, three groups of stations could be differentiated: stations directly affected by an ind...
