Accurate forecasting of electric load has always been the most important issues in the electricity industry, particularly for developing countries. Due to the various influences, electric load forecasting reveals highly nonlinear characteristics. This paper creates a system for power load forecasting using support vector machine and ant colony optimization. The method of colony optimization is ...

Bulk electric system reliability analysis is an important activity in both vertically integrated and unbundled electric power utilities. Competition and uncertainty in the new deregulated electric utility industry are serious concerns. New planning criteria with broader engineering consideration of transmission access and consistent risk assessment must be explicitly addressed. Modern developme...

There has been a continuous increase in automotive electric power usage. Future projections show no sign of it decreasing. Therefore, the automotive industry has a need to either improve the current 12 Volt automotive electrical system or move to a higher voltage vehicle electric system. Both of these choices are likely to increase cost of the system. Performance improvements will be needed to ...

As of 1998, electric utility companies burning coal or oil are required to report their annual releases of toxic chemicals to the Toxics Release Inventory (TRI), a national compilation of multimedia (air, water, land) releases of over 600 chemicals and chemical categories designated as toxic by the U.S. Environmental Protection Agency (EPA). TRI reports for 1998 must be filed with EPA by July 1...

Introduction: It is important that biological and health effects from the induction of currents and fields in the body by extremely low frequency (ELF) fields are fully explored to determine the effects produced at the molecular, cellular and organ levels. The objective of this study was to evaluate the intensity of ELF electromagnetic fields and its probable relationship with hematological cha...

Aluminium is the world’s second most-used metal after steel and the aluminium production industry is the largest, in volume of metal produced, in non-ferrous metal industry. In this study, results of the material flows (country and global scales) related to the production and use of aluminium and energy consumption in 1980 to 2012 were separately analysed. Also, overview of the current status o...

The culture of economic growth and rapid innovation has led the chemical industry to contaminate tens of thousands of locales with hazardous chemicals that are poorly understood. As a result, the chemical industry finds itself at war with citizens who are troubled by the widespread dissemination of industrial poisons and alarmed by the power and unaccountability of the corporations themselves. ...
