The Born-Oppenheimer Approximation (BOA) forms the basis for calculating electronically adiabatic potential energy surfaces, thus providing the framework for developing a molecular level understanding of a variety of important chemical problems. For surface chemistry at metal surfaces, it is now clear that for some processes electronically nonadiabatic effects can be important, even dominant; h...

Internet has been universally recognized as a medium for network-enabled transfer of information and knowledge in various areas. E-Learning technology, which delivers educational material electronically via the Internet, has been widely used in both academic education and corporative training. However, existing e-Learning systems have various limitations, such as presenting multimedia instructi...

A generalized structure that is capable of implementing power-law filters derived from 1st and 2nd-order mother filter functions presented in this work. This achieved thanks to the employment Operational Transconductance Amplifiers (OTAs) as active elements, because electronic tuning capability their transconductance parameter. Appropriate design examples are provided performance introduced eva...

This article presents an overview of selected general delivery options (e.g., videoconferencing, online learning, etc.) and specific software applications for developing and delivering instruction electronically, especially via the World Wide Web. A summary of the relative merits of developing customized software and of buying commercial software sets the stage for a brief review of 15 delivery...
