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

In recent years, evolution of technology has contributed a major role in the field of optical communication systems. There is an ever growing demand for transmitting signals at higher data rates and compensating the transmission impairments simultaneously. Speed of the signal transmission down the optical...

Vernal pools in the Northeastern United States are small, forested wetlands characterized by ephemeral flooding. These unique ecosystems provide critical habitat for both terrestrial and aquatic organisms, abate seasonal flooding, and are biogeochemical hotspots. Vernal pools may be created to maintain key ecosystem services... READ MORE
Anthropogenic nutrient pollution is one of the most serious threats facing aquatic systems in modern times. Pollution with compounds containing nitrogen and phosphorous encourages rapid development of autotrophic biomass, or blooms, that severely degrade the quality of an aquatic system both as a habitat...

Advances in next generation sequencing (NGS) technologies, in the past half decade, have enabled many novel genomic applications and have generated unprecedented amounts of new knowledge that is quickly changing how biomedical research is being conducted, as well as, how we view human diseases and...

Medical imaging modalities, including Computed Tomography (CT) Magnetic Resonance Imaging (MRI) and Ultrasound (US) are critical for the diagnosis and progress monitoring of many cardiac conditions, planning, visualization and delivery of therapy via minimally invasive intervention procedures, as well as for teaching, training and...

The spontaneous polarization in ferroelectrics (FE) makes them particularly attractive for non-volatile memory and logic applications. Non-volatile FRAM memories using perovskite structure materials, such as Lead Zirconate Titanate (PZT) and Strontium Bismuth Tantalate (SBT) have been studied for many years. However, because of their... READ MORE
Planetary nebulae (PNe) represent the late stages of low-mass stellar evolution. The formation of the myriad of PNe morphologies involves processes that are present in many other astrophysical systems such as the wind-blown bubbles of massive stars. In this dissertation we present the result... READ MORE
In the past several decades there has been increasing research into factors that may affect the birth sex ratio of parents. These can range from nutrition to hormone levels to psychological factors. The National Health and Nutritional Examination Survey (NHANES) is a broadly encompassing governmental... READ MORE
Green walls or living walls are architectural installations comprised of plants growing in soil filled, modular panels that are attached to interior or exterior walls. The objective of this study is to explore the effectiveness of using green walls to pretreat wastewater generated by small... READ MORE
A common flexible packaging laminate is comprised of five constructs in sequence: printing layer, adhesive, barrier layer, adhesive, and sealing layer. Aluminum foil and metallized polymer films are commonly used gas barrier layers in flexible packaging, but their true environmental impacts are not well-represented. This... READ MORE
In this work we demonstrate two separate forms of augmented reality environments for use with minimally-invasive surgical techniques. In Chapter 2 it is demonstrated how a video feed from a webcam, which could mimic a laparoscopic or endoscopic camera used during an interventional procedure, can... READ MORE
The characterization of the material properties of Single Molecule Magnets (SMMs) has grown in importance over the last few decades with the rise of novel applications such as high-density magnetic storage and quantum computation. Many of the applications require the probing of SMMs with... READ MORE
The enhancement of natural convection heat transfer using nanofluids from horizontal square cylinder placed in a square enclosure is investigated numerically. Water-based Cu is used as the working nanofluid. The investigation covered a range of Rayleigh numbers of 104 - 106, nanoparticles volume fraction of... READ MORE
The mathematical structure imposed by the thermodynamic critical point motivates an approximant that synthesizes two theoretically sound equations of state: the parametric and the virial. The former is constructed to describe the critical region, incorporating all scaling laws; the latter is an expansion about zero... READ MORE
