Electric Power and Energy Engineering: The First Century

Software Engineering in the Twenty-First Century

FALL 1992 71 By the year 2000, there will be a large potential market and a fertile environment for knowledge-based software engineering (KBSE). In the coming decade, hardware improvements will stimulate demand for large and sophisticated application software, and standardization of software interfaces and operating systems will intensify competition among software developers. In this environme...

Instantaneous electric energy and electric power dissipation in dispersive media

We derive the instantaneous densities of electric energy and electric power dissipation in lossless and lossy dispersive media for a time-harmonic electric field. The instantaneous quantities are decomposed into DC and AC components, some of which are shown to be independent of the dispersion of dielectric constants. The AC component of the instantaneous energy density can be used to visualize ...

Civil Engineering at the Crossroads in the Twenty-First Century

The twenty-first century presents a major challenge for civil engineering. The magnitude and future importance of some of the problems perceived by society are directly related to the field of the civil engineer, implying an inescapable burden of responsibility for a group whose technical soundness, rational approach and efficiency is highly valued and respected by the citizen. However, the sub...

Clean Hydrogen Energy and Electric Power Production with CO2 Capturing by Using Coal Gasification

Clean hydrogen is the major energy carrier for power production. The conversion of CO to CO2 and zero emission during hydrogen energy production causes high capital cost. It is a matter of prestige to optimize the process in order to make zero emission and cost effective production of clean hydrogen energy and electric power. In this era, coal gasification is th...
