Previous studies on low frequency flicker noise in bipolar junction transistors (BJT) are reviewed. The original BJT flicker noise sources are mainly attributed to the fluctuation in base surface recombination and the fluctuation in the mobility or diffusivity of free charge carriers. Our experiments were done to verify a newly...
The relationship of openness, growth and total factor productivity is investigated empirically using panel regressions for 48 countries. This study tests a variety of openness measures, including the ratio of trade (exports plus imports), imports, exports and primary exports to GDP. We also study the effects of the interaction of...
In 1959 the British Ornithological journal, The Ibis, published a centenary commemorative volume on the history of ornithology in Britain. Over the previous few decades, the contributors to this volume had helped focus the attention of ornithologists on the methods, priorities, and problems of modem biology, specifically the theory ofevolution...
The hypothesis that inoculation of transplants with vesicular-arbuscular mycorrhizal (VAM) fungi before planting into saline soils would alleviate salt effects on growth and productivity was tested on lettuce (Lactuca sativa L.) and onion (Allium cepa L.). A secondary hypothesis was that the fungi isolated from a saline soil would be...
With the arrival of European settlers to Western Oregon nearly 150 years ago came new methods of forest management. Early settlers' forest practices consisted of little more than harvesting what seemed an endless supply of timber. Forestry in the 20th century eventually incorporated such management concerns as re-forestation, biodiversity, wildlife...
The purpose of this study was to investigate the marketing strategies of custom clothing home-based business owners by identifying selected demographic characteristics, general business information, marketing strategies, and current and potential future marketing support from members who were custom clothier home-based business owners affiliated with the Professional Association of Custom...
Biohazardous waste refers to wastes that are potentially infectious to humans, as well as wastes from animal or plant research that could be potentially infectious to these organisms, or could alter their genetic selection process. Research resulting in generation of biohazardous waste is typically conducted at large, research-based universities. The...
Introduction: Recent reports in exercise related bone research have shown increased bone mineral content (BMC) at the femoral neck for prepubescent children participating in exercise programs consisting of repeated drop landings from a height of 61 cm. Increases in BMC from this type of exercise are believed to be the...
Recently, feminist scholars have begun to question the traditional telling of the history of rhetoric. Dissatisfied with a history which is told in terms of privileged, white males to the exclusion of all other voices, these scholars have worked to recover "lost" female rhetoricians and have begun critically rereading the...
The development of assays for stress in marine fishes is vital for studying the impacts of bycatch in fisheries and for determining the health of fish being cultured or used in research. This research developed behavioral and physiological assays for stress in juvenile sablefish, Anoplopoma fimbria, a species that comprises...
The harmonic problem in power systems is gaining more attention as incidences correlated with harmonics increase. Conventional passive filtering techniques for harmonic mitigation have inherent problems, and purely active filters have the disadvantages of higher costs and ratings. Hybrid active filters inherit the efficiency of passive filters and the improved...
Environmental monitoring poses two challenges to statistical analysis: complex data and complex survey designs. Monitoring for system health involves measuring physical, chemical, and biological properties that have complex relations. Exploring these relations is an integral part of understanding how systems are changing under stress. How does one explore high dimensional...
An analysis and modeling method of the diagnostic characteristics of a mechanical or electromechanical system is presented. Diagnosability analysis is especially relevant given the complexities and functional interdependencies of modern-day systems, since improvements in diagnosability can lead to a reduction of a system's life-cycle costs. The diagnosis process of a...
Fiber Bragg gratings have become an important element in the fields of telecommunications and fiber optical sensing. Their small size, light weight and high tunability have made them ideal for many unique applications. In this paper the fabrication of these devices is investigated.
Following a review of current literature and...
β-SiC is a semiconductor for high temperature devices, which exhibits several outstanding properties such as high thermal stability, good chemical stability and wide band gap. There is a possibility of fabricating a crack-free ultrathin SiC film on silicon wafers by pyrolysis of polymethylsilane (PMS) film.
This study looks into the...
Traditionally sinusoidal signal generation has been implemented with purely analog circuits such as phase-locked loops. The alternative of using a digital system to perform this signal generation has previously been unattractive due to limitations in clock frequency and size. However, recent advancements in sub-micron fabrication techniques have made the digital...
In this thesis, we develop a simulator for estimating the energy consumed in executing tasks on a mobile device - the Palm Pilot. We measured the energy consumed by each instruction of the device's assembly language and incorporated these measurements into a public domain emulator for the Palm Pilot. This...
Stress, including extreme or rapidly changing temperatures, are known to have deleterious effects on fish health and physiology. This thesis examines the combined effects of elevated acclimation temperature and acute handling stress on the number of antibody producing cells, plasma lysozyme concentrations, and the number of pronephric leukocytes in juvenile...
The purpose of this descriptive case study analysis was to provide portraits of the heuristics students used and difficulties they encountered solving conditional probability problems prior to and after two-week instruction on sample space, probability, and conditional probability. Further analysis consisted of evaluating the data in relation to a previously...
