Novel process and apparatus design for metalorganic chemical vapor deposition (MOCVD) of superconducting thin films
… review and analysis. Deficiencies in the design of these deposition processes, and deficiencies in the design of the mechanisms and tools used to carry out these processes are identified. Most of these deficiencies have resulted in either poor end-product performance or unlikely commercial …

Characterization and testing of a height adjustable kinematic coupling
… height adjustable kinematic coupling has been designed for a next generation high precision ceramics grinding machine designed to have total loop stiffness of 60 N/[mu]m. A test apparatus and prototype of the new coupling design has been built as the subject of this thesis to test the coupling …

Design of an electro-mechanical hexapod for accelerated life testing of optical fiber assemblies
… map of the universe ever produced [1,2]. The design advantages made possible by optical fibers also forms challenges to prevent damage to the fragile fibers that can lead to Focal Ratio Degradation (FRD) [3]. Therefore, a life cycle test must be conducted to study fiber behavior and measure …

Study to characterise the performance of micro tubular solid oxide fuel cells by the invention of an avant garde experimental apparatus and computational modelling.
… for any future MT-SOFC stack or testing apparatus design. This information has been achieved through a combination of experimental work, CFD modelling and numerical analysis. CFD models with an additional fuel cell module have been compared to experimental results for single cells with …

A novel direct shear apparatus to evaluate internal shear strength of geosynthetic clay liners for mining applications
… internal shear strength of GCLs is an important design consideration since GCLs often are installed on sloped surfaces that induced internal shear and normal stresses. The objective of this study was to develop a direct shear testing apparatus to measure the internal shear strength of GCLs for …
