Optimizing Placement of Weather Stations: Defining and Testing a Meaningful Objective for Multi-Variable Weather Monitoring Networks

Creator:: Snyder, Amelia M.
Abstract:: As the number of weather stations declines globally, ensuring that meteorological monitoring networks efficiently and effectively monitor weather variables becomes increasingly important. Multi-variable weather sensors are becoming more widely available and make monitoring weather phenomena more economical. However, when seeking an optimal spatial distribution of these stations, choosing an objective...

Why cosplay? Motivations behind participation and use of social media among cosplayers who maintain Facebook Artist Pages

Creator:: Kane, Laura E.
Abstract:: The purpose of this study was to explore motivations behind participation in cosplay and the use of social media among cosplayers who maintain Facebook Artist Pages. Further focus was placed on investigating the role of Facebook Artist Pages in building fame. To explore such motivations, two theories were referenced: Deci...

Hybrid Multiscale Methods with Applications to Semiconductors, Porous Media, and Materials Science

Creator:: Costa, Timothy B.
Abstract:: In this work we consider two multiscale applications with tremendous computational complexity at the lower scale. First, we examine a model for charge transport in semicon- ductor structures with heterojunction interfaces. Due to the complex physical phenomena at the interface, the model at the design scale is unable to adequately...

Flow-Solute : A Tool for Exploring the Effects of Nitrogen Management in Alternative Future Scenarios

Creator:: Wentworth, Andrew Michael
Abstract:: Surface water quality is a growing concern in the Willamette River Basin and elsewhere. The region's growing population is dependent on the availability of clean water for drinking water, irrigation, wastewater dilution, and wildlife habitat. Watershed management to produce economic goods and environmental services requires an understanding of basic hydrologic...

Revenue-based spectrum management via Markov decision process

Creator:: Zhu, Pingan
Abstract:: We consider the problem of wireless spectrum management in cognitive wireless networks that maximizes the revenue for a spectrum operator. Specifically, we study the problem on how a wireless spectrum operator can optimally allocate its limited spectrum to various classes users/devices who pay differently for their spectrum per unit time....

Stochastic properties of morphological filters

Creator:: Zhu, Feihong
Abstract:: Most of the existing research on mathematical morphology is restricted to the deterministic case. This thesis addresses the void in the results on the stochastic properties of morphological filters. The primary results include analysis of the stochastic properties of morphological operations, such as dilation, erosion, closing and opening. Two unbiased...

A performance study of multithreading

Creator:: Kwak, Hantak
Abstract:: As the performance gap between processor and memory grows, memory latency will be a major bottleneck in achieving high processor utilization. Multithreading has emerged as one of the most promising and exciting techniques used to tolerate memory latency by exploiting thread-level parallelism. The question however remains as to how effective...

Low-voltage switched-capacitor circuits

Creator:: Bidari, Emad
Abstract:: In recent years, the rapidly growth of CMOS technology has evolved towards submicron and deep-submicron features. Due to smaller device sizes, and significant demand for low-power designs, the maximum allowable power supply voltage is restricted. So far, two solutions; clock boosting and switched opamp schemes have been proposed. The material...

Two-grid a-priori and a-posteriori error analysis for coupled elliptic and parabolic systems with applications to flow and transport problems

Creator:: Klein, Viviane
Abstract:: We develop several a-priori and a-posteriori error estimates for two-grid finite element discretization of coupled elliptic and parabolic systems with a set of parameters P. We present numerical results that verify the convergence order of the numerical schemes predicted by the a-priori estimates. We present numerical results that verify the...

Calibration, characterization, and linear quadratic Gaussian estimation of sensor feedback signals for a novel ocean wave energy linear test bed

Creator:: Haller, Christopher A.
Abstract:: Continual growth of the world's energy consumption and the demand for long-term clean renewable energy resources has led to the development of ocean-based wave energy technologies. Emerging technologies are advancing potential solutions to the complex problem of energy generation in the harsh and corrosive ocean environment. To develop these technologies,...
