This thesis deals with 1/f noise in p-MOS, bipolar, and lateral bipolar transistors. Experimental measurements determine the appropriate 1/f noise for MOSFET's, bipolar transistors and lateral bipolar transistors. The literature on 1/f noise in p-MOSFETs, bipolar transistors and lateral bipolar transistors is reviewed. The two main sources of low frequency...
Vibrio parahaemolyticus is a seafood-borne pathogen that can cause gastroenteritis in humans. This study investigated the effectiveness of refrigerated seawater (5°C) depuration on reducing V. parahaemolyticus in raw Pacific oysters (Crassostrea gigas). Raw Pacific oysters were inoculated with a mixed culture of five clinical strains of V. parahaemolyticus and depurated...
Distribution of Vibrio parahaemolyticus in Oregon and Washington oystergrowing areas was studied between November 2002 and October 2003. V. parahaemolyticus was detected in 14.3% of oyster, 23.0% of seawater, and 44.4% of sediment samples with very low levels (≤7.4 MPN/g) of pathogenic strains being detected in oysters. Occurrence of V....
We demonstrated a low-cost and high-sensitivity DNA detection method using quantum dot-fullerene based molecular beacons (MBs) and magnetic nanoparticles. The MB tethered magnetic nanoparticles can be well dispersed in analytes for efficient DNA capture and concentrated by an external magnetic field for enhanced fluorescence signal detection. The detection requires only...
The dissertation focuses on the engineering of light-matter interaction using plasmonic nanoparticles and metamaterials to achieve enhanced luminescence and based on which to improve the performance of biosensing and light-emitting technologies. We designed and fabricated a spectrum of nanostructures to exhibit particular dispersion relations capable of controlling the spontaneous emission...
Further enhancement of energy generation is desired for practical application of anaerobic microbial systems such as microbial fuel cells (MFC) and anaerobic digesters (AD). A possible approach is to enhance the ability of microbial communities to transfer electron extracellularly in the form of electrical current. Critical to perform direct extracellular...
RNAs play important roles in the central dogma of molecular biology, and are involved in multiple biology processes such as chromatin modification, transcriptional interference and translation initiation. The functions of RNAs, especially non-coding RNAs, are highly related to its secondary structures, therefore computational methods for RNA structure prediction are of...
Objex is an object-oriented framework for producing C++ applications through specialization of a class library and interaction model. The problem addressed in this report is that of automatically producing C++ source code from Petri Network design descriptions of applications constructed from Objex components.
The approach is to add a code...
Counterfeits, unauthorized copies of a product presented for sale as if they were the legitimate manufacturer's product, are creating a sizeable and growing problem for the apparel and accessory industries (Olsen & Granzin, 1993). The purpose of the study was to investigate the relationship between consumers' likelihood of knowingly purchasing...
