This paper reports on the development of the process-planning module for EDAPS, an integrated system for designing and planning the manufacture of microwave modules. Microwave modules are complex devices having both electrical and mechanical properties, and EDAPS integrates electrical design, mechanical design, and process planning for both the mechanical and electrical domains. EDAPS's process...

Quantum-dot Cellular Automata (QCA) is an emerging and promising technology that provides significant improvements over CMOS. Recently QCA has been advocated as an applicant for implementing reversible circuits. However QCA, like other Nanotechnologies, suffers from a high fault rate. The main purpose of this paper is to develop a fault tolerant model of QCA circuits by redundancy in hardware a...

A Computer Aided Design (CAD) module was developed for determining some design parameters for a binary distillation column using the Lewis-Sorrel method and Visual Basic. The module made use of a data bank containing physical and thermodynamic properties of 18 substances. A sample design problem was solved using the module. Results from the module and manual calculations were very close.
