Design and Analysis of Free-space Optical Communications Systems for Next Generation Short-range Wireless Networks

Creator:: Liverman, Spencer
Abstract:: This dissertation focuses on indoor free-space optical communications systems for use in short range wireless networks. We propose that current radio frequency wireless links be augmented or replaced with optical frequency links due to overcrowding in the radio frequency spectrum. Optical frequencies contain hundreds of terahertz of unregulated bandwidth and...

A causal study of attitudes toward intercollegiate athletics of Oregon State University undergraduate students in three academic majors

Creator:: Ruhl, Glenn David
Abstract:: The purpose of this study was to determine and explain attitudes toward intercollegiate athletics of undergraduate students in three academic majors attending Oregon State University. The attitudes of a proportionate random sample consisting of 215 students were measured according to their responses to thirty-two Likert scale items containing six sub-scale...

Strategies for the development of sustainable agriculture in Bangladesh

Creator:: Islam, Md. Shahidul
Abstract:: The adoption of modem agricultural technologies in Bangladesh increases overall agricultural productivity and income primarily through the increase in cereal crop production. It, however, impedes the productivity of several other minor crops and fishes, widens the distribution of income between the rich and the poor, exploits resources and obstructs the...

Plasmonic Nano-Antenna and Modulator for On-Chip Optical Interconnects

Creator:: Gao, Qian
Abstract:: With the rapid growth of worldwide internet traffic in data centers and clouds, silicon photonics has been utilized to provide enormous data bandwidth and outstanding energy efficiency over electronics. Computing servers and storage servers that are connected by communication links are relying more on optical rather than electrical means mainly...

Specification of local surface weather elements from large-scale general circulation model information, with application to agricultural impact assessment

Creator:: Wilks, Daniel S.
Abstract:: A procedure for model-assisted climate impact assessment is developed. The approach combines data from observations and atmospheric general circulation models (GCNs), and provides the basis for a potentially valuable means of using information derived from GCMs for climate impact assessments on local scales. The first component of this procedure is...

Surface-Enhanced Infrared Absorption Gas Sensing Incorporating Advanced Plasmonic Nanostructures and Nano-Composite Materials

Creator:: Chong, Xinyuan
Abstract:: This dissertation focuses on extending the application scope of surface enhanced infrared absorption spectroscopy to gas sensing. The method we propose is incorporating plasmonic nanostructures with nano-composite material, metalorganic framework, which can selectively preconcentrate certain gas molecules into the nanopores. The preconcentrating property is first demonstrated by applying metal-organic framework...

Surface-Normal Modulation of Fano Resonances in Metallic Photonic Crystals for Free-Space Optical Interconnects

Creator:: Ren, Fanghui
Abstract:: This dissertation focuses on the development of ultra-compact optical devices for free-space modulation. We propose a surface-normal modulator using metallic photonic crystals for free-space optical interconnects. The active control of light intensity is achieved by engineering the Fano resonances in metallic photonic crystals. Both thermo-optic modulation and electro-optic modulation of...

The effect of dietary compounds on human cathelicidin antimicrobial peptide gene expression mediated through farnesoid X receptor and its potential role in gastrointestinal health

Creator:: Campbell, Yan
Abstract:: The human cathelicidin antimicrobial peptide (CAMP) is a broad spectrum microbicidal agent and modulator of both the innate and adaptive immune system. It is induced by 1,25-dihydroxyvitamin D (1,25(OH)₂D₃) through activation of the vitamin D receptor (VDR) and primary bile salts through activation of the xenobiotic nuclear receptor farnesoid X...

Understanding Public Perceptions of Post-Wildfire Landscape Recovery

Creator:: Kooistra, Chad M.
Abstract:: Forest disturbances, such as wildfires, pine beetle outbreaks, and floods are important features of many landscapes and ecosystems. Many disturbances are increasing in size, frequency, and intensity due to changing climates and land management decisions. The changing ecological and aesthetic conditions following a disturbance can lead to negative short- and...

Ultra-energy-efficient Silicon Photonic Modulators Driven by Transparent Conductive Oxides

Creator:: Li, Erwen
Abstract:: Silicon photonics has become the most promising platform for future large-scale optical interconnect and optical computing systems due to its inherent CMOS compatibility, which brings exclusive advantages in bandwidth density, energy efficiency, and cost effectiveness. Parallel optical interconnects based on photonic integrated circuits (PICs) have the capacity to meet the...
