The main achievement of this thesis is the development of a two-sheet charge simulation model with space charge creation by trap-to-band impact ionization to describe the electrical characteristics of alternating-current thin-film electroluminescent (ACTFEL) devices. The two-sheet charge model localizes all of the space charge in the phosphor region of an...
We present a theoretical free-space optical (FSO) transmitter that utilizes a dynamically steered and shaped laser beam to communicate with a randomly moving receiver adorned with a retroreflector. The transmitter tracks the receiver's position by repeatedly scanning the field of view (FOV), measuring reflections from the retroreflector, and estimating the...
Over the past few decades, a primary focus has been on the negative health effects of not participating in regular moderate-to-vigorous physical activity (MPVA). Only recently has sedentary behavior been studied as a distinct and independent risk factor for adverse health outcomes. This dissertation sought to provide new insights into...
The treatment of certain types of cancers brings with it serious physiological and
psychological side effects in cancer survivors, including: decreased aerobic capacity,
muscle wasting, body composition changes, fatigue, and a diminished overall quality of
life. Exercise may directly influence the physiological side effects of cancer and cancer
treatment, and...
In This Side of Paradise, The Great Gatsby, and several of his short stories, F. Scott Fitzgerald questions the importance of wealth as a factor in supporting happiness and fostering the American Dream on an individual basis. With these texts, Fitzgerald acknowledges that wealth is a factor and, simultaneously, a...
T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...
