strengthen existing concrete structures continues to expand as our current infrastructure
ages. However, one of the concerns when using FRP systems in this manner is...
Understanding of the band structure of the new nano materials is essential to have a deeper insight into their optical and electrical properties. Along with the existing techniques used for characterization of nano-materials, it is also important...
Sleep apnea syndromes; Overweight persons--Health and hygiene; Obesity
Overweight and obesity is a major contributing factor in an estimated 70% of all obstructive sleep apnea (OSA) cases. Approximately five percent of the adult population has OSA, and the numbers continue to soar with the rising prevalence of...
Iron oxide, Fe2O3, is a promising material for water splitting reaction using solar
energy due to its stability and optimal bandgap of 2 eV. Even the recent efforts, however,
using Fe2O3 thin film materials reported low efficiencies due to poor...
The vast knowledge of nucleic acids is evolving and it is now known that DNA can adopt highly complex, heterogeneous structures. Among the most intriguing are the G-quadruplex structures, which are thought to play a pivotal role in cancer...
The heat pipe augmented solar wall operates much more efficiently for domestic air heating than alternative passive solar technologies. The thermal diode effect of heat pipes reduces the insulating losses of the unit during nighttime and adverse...
Residential buildings account for a large portion of total energy consumption in the United States. Residential energy usage can be dramatically reduced by improving the efficiency of building envelope systems. One such method is to incorporate...
Hematite synthesized by low pressure oxygen plasma has been shown previously to exhibit promising characteristics as a photo-anode for a photoelectrochemical water splitting cell. It is cheap, stable and has a 2.1 eV bandgap and exhibits a...
The purpose of this dissertation was to demonstrate that a new method of direct intracellular energy delivery was effective in maintaining viability of in vitro Human Umbilical Vein Endothelial Cells (HUVECs) when exposed to chemical ischemia for...
I will report the development of a semi-empirical self-consistent and environment-dependent model Hamiltonian, which is intended to treat large systems in the order of 10000 atoms. This covers a range of important physical phenomena that are too...
Optimal trajectory generation is an essential part for robotic explorers to execute the total exploration of deep oceans or outer space planets while curiosity of human and technology advancements of society both require robots to search for...
Wind energy conversion systems; Wind power--Technological innovations; Wind power--Research
This thesis proposes a new Maximum Power Point Tracking (MPPT) algorithm employed in Wind Energy Conversion Systems (WECS). One of the major issues discussed in the literature concerning HCS is its inefficiency in detecting the peak power when...
A projected high penetration of battery electric vehicles (BEV s) in the market will introduce an additional load in the electricity grid. Furthermore, uncontrolled BEV charging from residential users will exacerbate the existing peak load during...
Rising environmental concerns due to our rising population ad energy demand along with our excessive dependence on fossil fuels has created an urgent need to find clean, renewable and carbon free source of energy. Photoelectrochemical (PEC) water...
Determining the mechanical properties of the spine is a significant step in understanding the behavior of the spine under normal conditions. Although a limited amount of data for cyclic loading is currently available, the tests are not completely...
Solar energy--Technological innovations; Electric current rectifiers
Solar energy offers a large potential as a source of energy and in light of financial
and ethical reasons, people are looking to harvest it for their energy needs. The
conversion of solar energy to electricity is performed by solar cells. There...
Hypoxia is characterized by an inadequate oxygen supply to the tissues in
proportion to their metabolic needs, and is a primary factor in traumatic CNS
injury, strokes, cardiopulmonary diseases, and obstructive sleep apnea. The
cAMP-dependent...
Energy independence requires that the nation reduce its dependence on foreign oil imports. This can be achieved through electrification of transportation vehicles if proper battery technology can be developed. In addition, the renewable energy...
The future of renewable energy technologies involves overcoming difficulties
with the creation of new materials. The use of nanotechnology has allowed for
inexpensive materials to achieve very interesting physical and electronic properties....
