Once entirely the domain of space-borne applications, the effects of high energy charged particles on electronics systems is now also a concern for terrestrial devices. Reconfigurable components such as FPGAs are particularly vulnerable to radiation single event effects (SEU) as they carry a large amount of memory within a relatively small amount of circuit area. This thesis presents a Silicon on Insulator (SOI) based configuration memory system in a radiation hard reconfiguration system.

This research project investigates the relationship between music composition, particularly electronic pop, and sound design (the editing/mixing of sound for cinema), with its main focus on Multi-channel (Surround Sound) techniques. It proposes new practices that extend music compositional tools into embracing spatial techniques employed by sound design. My research encompasses both the conceptual development (ie spatial techniques in creating narratives) and the practical issues relating to the production and technology needed for such works.

In recent years, optical orthogonal frequency division multiplexing (OOFDM) has emerged as a dominant research and development area in the field of high-speed optical communications. OFDM is a potential candidate as the most promising next-generation optical networks such as passive optical networks and optical transport networks, due to their simple configuration based on low cost, high speed data rates, high spectral efficiency, high quality of service and robustness against narrow band interference, frequency selective fading, and chromatic dispersion.

The enhancements of zero superconducting transition temperature (Tc,0) in Bi1.6Pb0.4Sr2Ca2- xNaxCu3O10+δ (BPSCCO) are reported. The BPSCCO samples (with x ranging from 0.00 to 0.06) were prepared by using the conventional solid state reaction technique. The properties of the samples were examined by using the X-ray diffraction (XRD), scanning electron microscopy (SEM), and the resistance versus temperature (R-T) measurements.

The adsorption of uranium (VI) by calcium alginate beads was examined by batch experiments. The effects of environmental conditions on U (VI) adsorption were studied, including contact time, pH, initial concentration of U (VI), and temperature. The alginate beads were characterized by using scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. Fourier transform infrared spectra indicated that hydroxyl and alkoxy groups are present at the surface of the beads.
