In rural sections the situation is differed j The means of raising revenue are often unsatisfactory; the distances to be traversed are Srea, ' communications are frequently bad; and_ th general educational, financial and sanitary levels are low. On the other hand, rural area contain the greatest number of people an^ fe they are the main sources of wealth of world, their sanitary environmental c...

Using optimization to design distribution systems became technically feasible a little more than two decades ago, and developments have occurred at a rapid rate ever since. These developments can be understood in terms of six evolutionary processes. Four are core: evolution of algorithms, data development tools, model features and software capabilities, and how companies actually use software f...

This paper examines the application of some techniques in Bluetooth communications expected to improve system’s performance under certain environmental conditions. The transmitter diversity Alamouti scheme [1] and receiver diversity have been evaluated and compared to the standard single antenna transmitter and receiver system by means of the achievable BER. Some analytical considerations about...

Having engaged one billion users by early 2006, the Internet is the world’s fastest-growing mass communications medium. As it permeates into countless lives across the planet, it offers social campaigners an opportunity to deploy interactive interventions that encourage populations to adopt healthy living, environmental protection and community development behaviours. Using a classic set of soc...

Quantum dot LEDs (QD-LEDs), which capitalize on the excellent color saturation and high photoluminescence efficiencies offered by quantum dots, promise to be part of future generations of display technologies [1]. The goal of our project is to integrate the already developed technology of the QD-LED into a resonant cavity (RC) and thereby achieve enhanced, directed electroluminescence (EL) that...

Environmental analysts are often hampered in communicating the risks of environmental contaminants due to the myriad of regulatory requirements that are applicable. The use of a qualitative, risk-based control banding strategy for assessment and control of potential environmental contaminants provides a standardized approach to improve risk communication. Presented is a model that provides an e...

although the history of communication is as old as history of human society, the speed and volume of communication with the advent of electronic era in the 19th century created a revolution in the communication technology. at a time when prussia was traversing the path of industrialization and the number of companies investing in different industries was increasing by the day, the company of si...

IEEE 802.11ah is a sub-1 GHz standard designed to meet the requirements of future machine-to-machine (M2M) communications. The standard should be able to support use cases for the M2M communications with thousands of stations capable of generating both periodic and aperiodic traffic for a single access point. In some cases, like environmental and agricultural monitoring, the nodes are typically...
