A Berg model application for ZrOX thin film deposition by DC reactive sputtering is presented. An alternative treatment to this model is proposed, focused on an engineering point of view. Berg model involves target poisoning as a compound covering a…

In this work we present a theoretical study of the spontaneous capillary flow of a viscous liquid, developed in the gap between a couple of parallel corrugated plates (corrugated Hele-Shaw cell). The periodical corrugation of the interior walls of the…

This paper describes a system for the computer understanding of English. The system answers questions, executes commands, and accepts information in normal English dialog. It uses semantic information and context to understand discourse and to disambiguate sentences. It combines a…

In recent years, researchers in artificial intelligence have become interested in replicating human physical reasoning talents in computers. One of the most important skills in this area is predicting how physical systems will behave. This thesis discusses an implemented program…

Anaesthetists are a group of doctors who are at a higher occupational risk of contracting blood borne infections as they perform many invasive procedures. Practice of Universal Precautions (UP) is vital in reducing the risk of transmission. The objective of…

This work extends the semantics and implementation of fuzzy prolog presented in [VGM02] in order to include Default Knowledge capability. The new semantic allows non-uniform default assumptions and has Closed World Assumption (CWA) and Open World Assumption (OWA) as particular…
