The Effects Of Multi-Channel Visible Spectrum Imaging On Perceived Spatial Image Quality And Color Reproduction Accuracy, Ellen A. Day

Theses

Two paired-comparison psychophysical experiments were performed. The stimuli consisted of six image types resultingfrom several multispectral image-capture and reconstruction techniques. A seventh image type, color-managed images from a high-end consumer camera, was also included in thefirst experiment to compare the accuracy of commercial RGB imaging. The images were evaluated under simulated daylight (6800K) and incandescent (2700K) illumination. The first experiment evaluated color reproduction accuracy. Under simulated daylight, the subjects judged all of the images to have the same color accuracy, except the consumer camera image which was significantly worse. Under incandescent illumination, all the images, including the consumer camera, had …

Nature Through Sculpture, Jaewon Lee

Theses

"Human beings were born from nature and in death they return back to nature." This quote express how closely we are connected to nature which is defined a word as all the plants, animals and things that exist in the universe that are not made by people. We first came from nature, and in this complicated society, we sometimes feel like returning to the peaceful, magnificent and tranquil side of nature. Through my work, I would like to show his interpretation of how nature is. For example, a person can look at the ocean and feel peaceful, but someone else …

Theses

As the era changed, education programs have developed tremendously and there are more people who seek for a new way to study easier. A game is one way to learn new skills; Network games especially can be used most effectively to support the goal of education. I believe that people can gain more knowledge through competitive games than memorizing by them selves. Some might think network games are not needed because there is no need for other people when you can compete with a computer, but There are limitations using just a computer and people feel more competitive when they …

Assessment Of Groundwater Resources In Selected Areas Of Al Ain In The U.A.E., Fatma Abdullatif Al Shahi

Theses

The sustainable development of any region depends on the availability of water resources. In arid and semi-arid regions, the shortage in freshwater resources constitutes the major constraint against the expansion in agricultural and industrial activities. Therefore, every possible effort should be made to assess, develop and sustain the limited freshwater water resource in such regions.

The United Arab Emirates (UAE) is located in an arid region, where the climate is harsh and the renewable freshwater resources are very limited. Despite the severe shortage in water resources, water is misused and sometimes wasted. The per capita daily consumption in the UAE …

Dimensional Study Of Desaminotyrosyl Polyarylates, Kalsank Vaishali Pai

Theses

Synthetic polymers have found widespread usage and acceptance in various areas of the medical device industry. The recognition that no polymeric biornaterials are truly biocompatible has led to the search for bioerodible materials with desirable biological and physical properties for use as tissue engineering scaffolds and to enable in-vivo devices. Several methodologies have been tried and tested to invent the "ideal" biopolymer. The ideal polymeric biomaterial would be one that offers a favorable response at both the cellular and the systemic level with minimum alteration to its mechanical properties and chemistry. The systematic investigation of process-structure-property space to determine the …

Quantitative Assessment Of Reflex Blood Pressure Regulation Using A Dynamic Model Of The Cardiovascular System, Tanha Patel

Theses

A quantitative understanding of the changes in coronary, pulmonary and systemic hemodynamic variables and their effects on the regulation mechanism is important to the better postoperative management of patients with impaired cardiac function. The arterial baroreflex plays a key role in blood pressure homeostasis, and its impairment may result in exaggerated blood pressure fluctuations and an increased risk of cardiovascular morbid events.

The objective of this work was to construct a mathematical model of the cardiovascular system, which will allow us to simulate the effects of the baroreceptor reflex regulation on sudden changes in blood pressure, caused by sudden changes …

Cortical Response To Facial Expressions Of Young Adult Males With Autism Spectrum Disorders And Controls Using Functional Magnetic Resonance Imaging (Fmri), Jagriti Arora

Theses

Autism is a neurodevelopmental disorder that is defined by deficits in social and emotional impairments and this study aims to identify specific brain regions involved during facial processing. The simple task of focusing on the face during social interactions for the normal group is found difficult by the autistic group.

In this study, functional magnetic resonance imaging (fMRI) was used as subjects performed two experimental tasks (EXPLICIT and IMPLICIT) in which a series of photographs of nine males and nine females displaying three affective states (6 fear, 6 happy and 6 neutral) and six scrambled- face control stimuli were presented …

Masseter Muscle Activity Resulting From Stimulation Of Hypothalamic Behavioral Sites : Wavelet Analysis, Anne Marie Petrock

Theses

Patterns of electromyographic (EMG) activity can give an insight into muscle activity associated with a given behavioral state. The masseter muscle is positioned closely to the temporomandibular joint and controls the position and movement of the jaw. The hypothalamus is the region of the brain associated with emotional behavior. In an effort to further understand the muscle activity underlying emotional display, the hypothalamus in two cats was stimulated to evoke a stereotyped emotional response, known as the "rage response." Unsheathing of the claws, retraction of the ears, significant pupillary dilation and vocalization (hissing) characterize this behavior. EMG data obtained at …

Atomic Force Microscopy Used To Determine The Young's Modulus Of Vascular Smooth Muscle Cells, Samuel C. Lieber

Theses

The Young's modulus of cultured mouse and rat vascular smooth muscle cells (VSMC) was measured with an atomic force microscope (AFM). The AFM can image the three-dimensional structure of biological cells in a physiological environment enabling real-time biochemical and physiological processes to be monitored at a resolution similar to that obtained for the electron microscope (EM). Cellular mechanical properties were determined by indenting the cell's body, and analyzing the indentation data with classical infinitesimal strain theory. This calculation was accomplished by modeling the AFM probe as a cone. as well as a blunted cone. The blunted cone geometry fits the …

This study provides valuable information about existing FMS workcells and brings to light a unique concept called Programmable Automation.

Another integrated concept of programmable automation that is discussed is the use of two feasibility approaches towards modeling and controlling FMS operations; the most commonly used is programmable logic controllers (PLC), and the other one, which has not yet implemented in many industrial applications is Petri Net controllers (PN). This latter method is a unique powerful technique to …

Sustainable Agriculture : Pragmatism, Distinctions On Artifacts And The Role Of The Land Ethic, Dustin Mulvaney

Theses

This thesis will explore the ethical dimensions of global agriculture from the productionist paradigm to the land ethic in the context of the sustainable agriculture promoted in the fair trade, shade grown, and organic coffee movements. Much of the sustainable development debate in the environmental ethics literature has centered on justifications (from anthropocentric and nonanthropocentric worldviews) for preserving nature. Since agriculture is an artifact of human sedentary civilization, traditional nonanthropocentric arguments do not suffice because of the tendency to focus exclusively on natural systems. Building on the work of Katz's "Pragmatic ReConsideration" and Light's "methodological pragmatism," the role of anthropocentric …

Development Of A Method To Examine Shear Stress On Cardiomyocytes, Dhawal Desai

Theses

Cardiac hypertrophy is the remodeling or enlargement of the heart exhibited by individuals suffering from heart disease. Cardiac hypertrophy involves two mechanisms, mechanical stresses and humoral changes in the cardiac tissue. One such humoral change involves the Renin Angiotensin System (RAS). The primary fimction of RAS is maintenance of hemodynamics of the body mediated through an effector protein, Angiotensin 11. However, RAS has been shown to play a significant role in the pathophysiology of the heart; contributing to hypertension, cardiac hypertrophy and myocardial infarction. RAS acts through binding of Angiotensin 11 at its receptors. The two forms of Angiotensin 11 …
