Dielectrophoresis (DEP) is an electrokinetic (EK) transport mechanism that exploits polarization effects when particles are exposed to a non-uniform electric field. This dissertation focused on the development of high-performance insulator-based DEP (iDEP) devices. A detailed analysis of the spatial forces that contribute to particle... READ MORE
With the goal of enhancing the emission of ultra-sound (US) waves in photoacoustic imaging (PAI) for the detection of cancer we discovered an effective system for Förster Resonance Energy Transfer (FRET) composed of a near infrared fluorescent (NIRF) dye and a NIR quencher (NIRQ)... READ MORE
Computer vision can make important contributions to the analysis of remote sensing satellite or aerial imagery. However, the resolution of early satellite imagery was not sufficient to provide useful spatial features. The situation is changing with the advent of very-high-spatial-resolution (VHR) imaging sensors. This... READ MORE
Reference data ("ground truth") maps traditionally have been used to assess the accuracy of imaging spectrometer classification algorithms. However, these reference data can be prohibitively expensive to produce, often do not include sub-pixel abundance estimates necessary to assess spectral unmixing algorithms, and lack published...

Compiler infrastructures are often an area of high interest for research. As the necessity for digital information and technology increases, so does the need for an increase in the performance of digital hardware. The main component in most complex digital systems is the central... READ MORE
Recent research in academic analytics has focused on predicting student performance within, and sometimes across courses for the purpose of informing early interventions. While such an endeavor has obvious merit, modern contructivist learning theory expresses an importance on more individualized support for students. ... READ MORE
The obscuring circumnuclear torus of dusty molecular gas is one of the major components of AGN (active galactic nuclei), yet its size, composition, and structure are not well understood. These properties can be studied by analyzing the temporal variations of the infrared (IR) dust... READ MORE
For many years ferroelectric memory has been used in applications requiring low power, yet mainstream adoption has been stifled due to integration and scaling issues. With the renewed interest in these devices due to the recent discovery of ferroelectricity in HfO2, it is imperative... READ MORE
Natural disasters, such as earthquakes and hurricanes, are an unpreventable component of the complex and changing environment we live in. Continued research and advancement in disaster mitigation through prediction of and preparation for impacts have undoubtedly saved many lives and prevented significant amounts of... READ MORE
There are inherent safety risks associated with inactive lithium ion batteries leading to greater restrictions and regulations on shipping and storage. Maintaining all cells of a lithium ion battery at near zero voltage with an applied fixed resistive load is one promising approach... READ MORE
Gravitational waves (GWs) are propagating ripples of space-time predicted by general relativity. 100 years after Albert Einstein published his theory of GR, the Laser Interferometer Gravitational-Wave Observatory (LIGO) found the first direct detection of GW in the first Advanced LIGO observing run. The GW... READ MORE
The objective was to develop and characterize a potential method to alleviate the issues regarding post impact effective modulus of composites in a tubular geometry. The hypothesis was that the use of a metallic substrate may increase post impact stiffness characteristics of the sample... READ MORE
The field of computer vision has long strived to extract understanding from images and videos sequences. The recent flood of video data along with massive increments in computing power have provided the perfect environment to generate advanced research to extract intelligence from video data....

The loss of natural wetlands to anthropogenic development has warranted the creation of wetlands to mitigate the reduction of valuable ecosystem functions and services. However, the complex interactions between the main drivers of wetland community structure – hydrology, nutrient availability and herbivory – makes... READ MORE
The objective of this study is to analyze the potential for Unmanned Aerial Vehicles (UAVs) to displace current technology and look at how they impact the environment through a delivery transportation model. It is meant to encompass an ecological perspective of producing and using... READ MORE
According to the currently prevailing cosmological paradigm, mergers between galaxies are an important part of their evolution. Assuming also that most galaxies contain a supermassive black hole at their center, binary supermassive black holes (BSBH) should be common products of galactic mergers. The subject of... READ MORE
The rapid proliferation of consumer small unmanned aerial systems (sUASs) has expanded ownership to include amateurs and professionals alike. These platforms in combination with numerous open source and proprietary applications tailored to gather aerial imagery and generate 3D point clouds and meshes from aerial... READ MORE
Groundwater contamination is an extremely important topic in environmental science. Ex-situ removal of contaminants is costly and largely ineffective on contaminants that have high vapor pressures and readily mix with water. Bioremediation or bio-augmentation are attractive alternative ways to remediate a site, as they... READ MORE
Controlled doping of semiconductor material with high atomic accuracy and minimum defects in silicon is needed for next generation nanoscale and solar devices. The molecular monolayer doping (MLD) strategy is a novel technique based on the formation of self-assembled monolayer of dopant –containing molecule... READ MORE
The Smart Grid (SG) is an emerging modernized electrical power system with advanced monitoring and control mechanism, and improved faulttolerance. The SG converges traditional power grid with a bidirectional communication and information system into the same infrastructure. Electric Vehicles (EVs), with their energy storage... READ MORE
Carbon nanotube arrays have been found to be highly effective at carrying out intracellular delivery of cargo at high efficiencies while ensuring cell viability. Template based chemical vapor deposition is a commonly used process to fabricate these arrays. However, current etching methods used to... READ MORE
Processors and embedded systems perform algebraic manipulations such as addition, subtraction, multiplication and division on integers in order to complete and execute programs. Unfortunately, most division cores in these devices take significantly more time to compute than other manipulations. Because of this, research has been... READ MORE
