Engineering, Science, & Technology

Creating, innovating, addressing challenges, solving problems, and improving the quality of lives in society.

The Army Research Lab conducted a persistent imaging experiment called the Spectral and Polarimetric Imagery Collection Experiment (SPICE) in 2012 and 2013 which focused on collecting and exploiting long wave infrared hyperspectral and polarimetric imagery. A part of this dataset was made for public... READ MORE
Although joysticks on motorized wheelchairs have improved the lives of so many, patients with Parkinson's, stroke, limb injury, or vision problems need alternate solutions. Further, navigating wheelchairs through cluttered environments without colliding into objects or people can be a challenging task. Due to these... READ MORE
Silicon Photonics is a promising new technology for realizing efficient, high performance interconnects. There is a growing need for educating future engineers on how to design, fabricate, package and test silicon photonic circuits. Silicon photonic processing for an educational institution with i-line lithography capabilities... READ MORE
Autonomous, self-navigating agents have been rising in popularity due to a push for a more technologically aided future. From cars to vacuum cleaners, the applications of self-navigating agents are vast and span many different fields and aspects of life. As the demand for these autonomous... READ MORE
The prevailing model of structure formation that describes how matter is distributed throughout the Universe is known as the Lambda Cold Dark Matter paradigm. A key component of this paradigm is dark matter, which has so far gone undetected in laboratory experiments but is... READ MORE
Video understanding has become increasingly important as surveillance, social, and informational videos weave themselves into our everyday lives. Video captioning offers a simple way to summarize, index, and search the data. Most video captioning models utilize a video encoder and captioning decoder framework. Hierarchical encoders...

Amorphous oxide semiconductors (AOS) have been extensively studied for their application in thin-film electronics; an area which is currently dominated by hydrogenated amorphous silicon (a Si:H) technology. Indium-gallium-zinc oxide (IGZO) has garnered most of the AOS materials focus due to its high carrier mobility and... READ MORE
Selecting the capacity of a central air conditioning (AC) system is based on a long list of structural factors within a home, but is normally chosen without considering effects on stakeholders outside of the home. Energy use by residential air conditioners is relevant to... READ MORE
Industries are aware of the costs of high electricity consumption and its impact on the environment. Therefore, significant focus is given on how to reduce the consumption of electricity to lower both the carbon footprint and the cost of electricity. There are two ways... READ MORE
A three-dimensional (3D) cell culture system provides an effective platform to study cell dynamics in in vivo-mimicking conditions and thus plays an important role in understanding cell biology, organ function, and disease model. This dissertation investigates cell dynamics in a variety of 3D environments... READ MORE
Metal-oxide chemical sensor technology has been praised as a cheap and efficient method of detecting both reducing and oxidizing gases depending on the metal-oxide’s carrier type. The research conducted in this thesis explored methods of enhancing the sensitivity of an n-type metal-oxide material (indium... READ MORE
Organic photovoltaics (OPV) offer great promise as a low-cost renewable energy source, the relative low efficiency still challenges its commercialization potential. Small conjugated molecules like Squaraine (SQ) molecules show promising advancement in organic photovoltaics (OPV). Advantages of SQ over other materials is that it... READ MORE
Recently, algorithms for object recognition and related tasks have become sufficiently proficient that new vision tasks can now be pursued. In this paper, we build a system capable of answering open-ended text-based questions about images, which is known as Visual Question Answering (VQA). Our approach’s... READ MORE
In this work we study the potential for utilizing the scattering of polarized neutrons from nuclei whose spin has been modulated using nuclear magnetic resonance (NMR). From first principles, we present an in-depth development of the differential scattering cross sections that would arise in such... READ MORE
