Organic solar cells have the potential to be portable power sources that are light-weight, flexible, and inexpensive. However, the highest power conversion efficiency for organic solar cells to date is ~8%, and most high-efficiency solar cells have an area of less than 1 cm^2. This thesis advances the field of organic solar cells by studying the physics and engineering ....

The use of metallic material systems (e.g. pure metals, alloys, metal matrix composites) in a wide range of engineering applications from medical devices to electronic components to automobiles continues to motivate the development of improved constitutive models to meet increased performance demands while minimizing cost. Emerging technologies often incorporate materia....

A new method for enhancing rates of enzymatic hydrolysis for cellulosic fiber is presented. By adding a cationic polyelectrolyte to a cellulase/cellulose hydrolytic system, the polyelectrolyte binds to the cellulase and fiber forming flocs. The cellulase is bound by a patching mechanism. By using this technique, the rate of enzymatic hydrolysis can be enhanced. This the....

Computer vision encompasses a host of computational techniques to process visual information. Medical imagery is one particular area of application where data comes in various forms: X-rays, ultrasound probes, MRI volumes, EEG recordings, NMR spectroscopy, etc. This dissertation is concerned with techniques for accurate reconstruction of neural pathways from diffusion m....

Medical imagery is increasingly evolving towards higher resolution and throughput. The increasing volume of data and the usage of multiple and often novel imaging modalities necessitates the use of mathematical and computational techniques for quicker, more accurate and more robust analysis of medical imagery. The fields of computer vision and machine learning provide a....

The objective of this thesis is to develop circuit-aware interconnect technology optimization for network-on-chip based many-core architectures. The dimensions of global interconnects in many-core chips are optimized for maximum bandwidth density and minimum delay taking into account network-on-chip router latency and size effects of copper. The optimal dimensions thus ....

Organic materials are ubiquitous in the geologic environment, and can exert significant influence over the interfacial properties of minerals. However, due to the complexity in their structure and interaction with soil solids, their impact has remained relatively unquantified. This study investigated the engineering behaviors of organoclays, which were synthesized in th....

Novel solvents utilizing a reversible CO2 induced property switch are presented. The synthetic procedure for designing the solvents is discussed, along with detailed characterizations on both solvent forms to serve as a tool for optimal solvent identification as well as future solvent design. A reflectance infrared spectroscopic technique is introduced to allow for the ....

Trapdoor functions, introduced in the seminal paper of Diffie and Hellman, are a fundamental notion in modern cryptography. Informally, trapdoor functions are injective functions that are easy to evaluate but hard to invert unless given an additional input called the trapdoor. Specifically, the classical security notion considered for trapdoor functions is one-wayness, ....

The exact mechanisms responsible for heating the solar atmosphere in regions such as the chromosphere (partially ionized) and the corona (fully ionized) remain quantitatively unknown. This thesis demonstrates that the ions can be heated by Alfven waves with low frequencies in fully and partially ionized low beta plasmas, which is contrary to the customary expectation. F....

Massively multiplayer online games (MMOGs) present fantastic, persistent worlds and narratives for a community of players to experience through pre-defined rules, roles, and environments. To be able to offer the opportunity for every player to try the same experiences, many game developers have opted to create elaborate virtual theme parks: scripted experiences within s....

Emerging contaminants are defined as synthetic or naturally occurring chemicals or microorganisms that are not currently regulated but have the potential to enter the environment and cause adverse ecological and/or human health effects. With recent development in analytical techniques, emerging contaminants have been detected in wastewater, source water, and finished dr....
