The Layered Patination Of Copper, Ronald Vanostrand

Theses

This thesis was a pragmatic exploration into die patination process of copper. Two particular process elements were researched; patina layering and manipulation of the environment in which patination occurs. The success of the process will be determined by the permanence, consistency, durability and aesthetic worth of the resulting patina. The primary process element, that of patina layering, was comprised of a hot immersion process followed by compatibility tests with a subsequent exposure to fumed, sprayed, and saturated suspension processes. Initial and subsequent surface preparations were required. Additionally the process element of environment and its effects, both visually and texturally on …

A Vascular Flora Of Jackson County, Alabama, Kristin Renée Brodeur

Theses

The county is herein documented to support 1,272 species and infraspecific taxa. During the course of this study, 359 county records were produced, and 18 new taxa were recorded as occurring in the state for the first time. The vascular flora is demonstrably rich, even in comparison to other ecosystematic studies completed within the State. In contrast to other counties and in conformity with a long land and water use history, Jackson County has nearly 20% of the flora comprising alien taxa. As expected and evidenced by the life-form spectra dominated by hemicryptophytes and therophytes, the species are well-adapted to …

The Effects Of Flow Rate And Sodium Laurel Sulfate Surfactant Concentration On Single- And Two-Phase Heat Transfer Characteristics In A Microchannel, Michael June

Theses

The processing speed of modern microchips and the density of components at the card level has been increasing at a steady rate. With these increases, come an increase in heat generation and a need to dissipate very high heat fluxes. Heat sinks that employ very narrow channels, on the order of 58 - 600um wide have been shown to dissipate heat fluxes as high as 10,000 kW/m2 (Tuckerman, 1984) while maintaining chip temperatures below 130 C. The current study investigates the heat transfer characteristics of single and two-phase flows in a 200 Jim wide channel. Water was used as a …

A Study Of The Stability Of A Hydraulic Actuator System, Paul Stoelting

Theses

One of the least desirable schemes for a linear electro-hydraulic motion control actuator is having a low backup structure stiffness coupled with a high flow gain of the spool valve. It has been demonstrated that this condition causes instability in the form of high frequency oscillations. This thesis examines how actuator parameters can be varied to add stability when a low backup structure stiffness and high flow gain are mandatory design criteria. The stability of the system is examined by developing the system characteristic equation and analyzing its poles in the complex frequency domain. In the complex frequency domain, the …

A Paradigm For Color Gamut Mapping Of Pictorial Images, Gustav J. Braun

Theses

In this thesis, a paradigm was generated for color gamut mapping of pictorial images. This involved the development and testing of: 1.) a hue-corrected version of the CIELAB color space, 2.) an image-dependent sigmoidal-lightness-rescaling process, 3.) an image-gamut- based chromatic-compression process, and 4.) a gamut-expansion process. This gamut-mapping paradigm was tested against some gamut-mapping strategies published in the literature. Reproductions generated by gamut mapping in a hue-corrected CIELAB color space more accurately preserved the perceived hue of the original scenes compared to reproductions generated using the CIELAB color space. The results of three gamut-mapping experiments showed that the contrast-preserving nature …

Spectral-Based Color Separation Algorithm Development For Multiple-Ink Color Reproduction, Di-Yuan Tzeng

Theses

Conventional four-color printing systems are limited by an insufficient number of degrees of freedom for tuning the visible region of the spectrum; as a consequence, they are often limited to metameric color reproductions. That is, color matches defined for a single observer and illuminant (usually CIE illuminant D50 and the 1931 standard observer) are often unstable when viewed under other illuminants or by other observers. For critical color-matching applications, such as catalog sales and artwork reproductions, the results are usually disappointing due to typical uncontrolled lighting and viewing. Furthermore, the existing multiple-ink printing systems, which all focus on expanding color …

An Analysis On The Effects Of Social Context In The Display Of Anger In Children, Angie Vanmeter

Theses

The purpose of t his research is to determine if social context influences a child's decision to regulate their anger. The subjects used in this study were 20 first, third and sixth grade students totaling sixty children. The categories of social context are as follows: parent, peer and alone. The subjects completed a demographic survey, as well as an aggression questionnaire, designed by the researcher. The results confirmed previous research with regard to the influence social acceptance has over children's actions. This research indicates peers, as being the most influential category in determining a child's response to anger.

Measurement Of Residual Stress In Electrodeposited Nickel Films, Gary Richardson

Theses

For nearly as long as people have had the ability to create deposits by electrodeposition it has been known that the deposits are made in a state of internal stress. Throughout the past one hundred years several simple techniques used to measure these stresses have been developed. Unfortunately these methods have several shortcomings in both their formulation and interpretation, and seldom have the results from any of these tests been verified by another method. As electroplating becomes utilized to a greater extent in the high-tech applications of aerospace, optics, and electronics it is becoming ever more crucial to gain the …

Judged, Lawrence Neuberger

Theses

Judged is a film about the subconscious battle between good and evil. The way I see it, every person has a good side and a bad side. No matter how good a person is, there is always an evil side lurking in the back of their mind. Not every person acts upon this evil side. For some people, this evil side just takes over. For some others it is brought out by some other act. In this instance, a normal man is recruited to go to war. A gun is put in his hands and he is forced to kill. …

The Use Of Silica And Alumina To Catalyze The Addition Of Hydrogen Chloride To Alkenes, Ying Liu

Theses

The use of pre-heated silica gel and alumina along with a chlorinating agent, generates HC1 in situ, which has been found to add to norbornadiene ( IX ). Treated in this fashion, norbornadiene readily results in the formation of two isomers, exo-5- chloronorbornene ( XI ) and 3-chloronotricyclene ( XII ) at room temperature in methylene chloride, with ejco-5-chloronorbornene being the predominant product ( 70% 1% ). In promoting the hydrohalogenation reaction, silica gel was found to be less efficient compared to alumina, but undesired diadducts appeared to be less prominent when silica gel rather than alumina was used. Deuterated …

Comparative Molecular Field Analysis (Comfa) Of Phenyl Ring Substituted Methylphenidates, Milind Misra

Theses

Comparative Molecular Field Analysis (CoMFA) was performed on 30 methylphenidate analogues having phenyl ring substituents at the 2-, 3-, and 4-positions in an attempt to explain the structure-activity relationships of the analogues. Several CoMFA studies were carried out using different conformations of methylphenidate as the template structures for the corresponding alignment rules. The identification of the bioactive conformation was variously based on the interfeature distances in WIN 35,428, on cluster analysis, and on a comparison of active methylphenidate analogues. The sensitivity of the models to various CoMFA parameters was compared. These parameters included altering the size and spacing of the …

Alcoholism : Medicalization By The Masses In Post-Prohibition America, Stephen Raymond Patnode

Theses

The medicalization of America is typically presented as a top-down, doctor-driven phenomenon. I argue that in the case of alcoholism, this model leaves out the community-level social activism of individuals who were identifying themselves as members of Alcoholics Anonymous. Any description of the popularization of the disease concept of alcoholism that does not take into account the efforts of these individuals is missing a key element. My thesis attempts to incorporate these individuals into the historical narrative.

If we are to focus on the efforts of Alcoholics Anonymous in framing alcoholism as a disease, the 1930s represent a crucial turning …

Study Of The Effects Of Deuterium Implantation Upon The Performance Of Thin-Oxide Cmos Devices, Sumit Kishore

Theses

The use of ultra thin oxide films in modem semiconductor devices makes them increasingly susceptible to damage due to the hot carrier damage. Deuterium in place of hydrogen was introduced by ion implantation at the silicon oxide-silicon interface during fabrication to satisfy the dangling bonds. Deuterium was implanted at energies of 15, 25 and 35 keV and at a dose of 1x10¹⁴/cm². Some of the wafers were subjected to N₂O annealing following gate oxide growth. It was demonstrated that ion implantation is an effective means of introduction of deuterium. Deuterium implantation brings about a …

Mutual Interference Investigation Of Cebus And X-10 Powerline Signaling, Sajid Pallithotungal

Theses

Powerline control signaling using CEBus has great potential towards inexpensive home automation. CEBus transmits at 10 kBps using spread spectrum in the 100-400 kHz band while X-l0 sends 60 Bps using bursts of 120 kHz carrier on the power line. However, these two signals may destructively interfere when present simultaneously. X-10 is narrow band and interferes with the CEBus spread spectrum signal. This thesis looks into the mutual interference patterns of Power Line CEBus communication in the presence of X-l0 module signaling and visa versa. The investigation encompasses a series of tests and measurements on a Power Line CEBus-X10 test …
