Spectral Approaches To Natural Mesh Processing, Takamitsu Kawai

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mesh design is a major bottleneck in the creation of computer games and animation. Therefore simplifying the process of mesh editing is an important problem. Natural mesh processing is generally difficult to perform since natural meshes often have nontrivial surface shapes and high degrees of freedom. In this study I present novel approaches to natural mesh processing utilizing spectral methods based on the manifold harmonic basis.;Geometric scaling transformations do not respect the biological processes which govern the size and shape of living creatures. I describe an approach to scaling which can be related to biological function. Known biological laws of …

Selective Self-Stereotyping And Women’S Self-Esteem Maintenance, Debra L. Oswald, Kristine M. Chapleau

Psychology Faculty Research and Publications

The process and implications of gender-based self-stereotyping are examined in this paper. Women displayed a tendency to selectively self-stereotype for personality and physical traits such that they endorsed positive stereotypic traits and denied negative traits as descriptive of the self and closest women friends. However, negative traits were endorsed as descriptive of women in general. Cognitive stereotypes were endorsed as more descriptive of all women than of the general university student. The tendency to selectively self-stereotype on physical traits was positively associated with appearance, social, and performance self-esteem. The results are discussed for their theoretical and practical implications.

Normative Reflectance And Transmittance Measurements On Healthy Newborn And 1-Month-Old Infants, Gabrielle R. Merchant, Nicholas J. Horton, Susan E. Voss

Despite ongoing efforts of the federal and state government, as well as those of the local school districts, this problem continues to burden the educational system and society as a whole. The opinions of those with the experience of dropping out and returning to school are pertinent sources of information on educative practices that can help stem the dropout rate.

A survey was conducted to gather the opinions of students …

Administrators' And Teachers' Perceptions Of In-School Suspension, Amelia Shondra Jackson

Dissertations

Providing a safe and orderly school environment for students to learn is of paramount importance to school administrators, teachers, students, and the general public; however, the learning process should not be compromised while trying to maintain such an environment. There are many alternative approaches that can be utilized that would rectify the problem we as educators face in providing a safe and orderly environment. At-risk students are usually the ones who have the most serious infractions. These students exhibit a cyclical pattern of recalcitrant behavior. It is imperative that these at-risk students be identified as early as possible, and intervention …

Emotional Maturity Of Adolescents And Adults In Ged Programs, Billy Joe Riffle

Dissertations

When discussing issues relating to students in General Educational Development (GED) Option and pre-GED programs with educators, the contention exists that it is possible to make reasonably accurate predictions on the success or failure of a student by observing a number of items. Looking at their cumulative records shows their academic and attendance history. Insight is gained by looking at their family dynamics and how they relate to adults. Much can be learned about them from their discipline reports and the nature of any infractions. One of the most intriguing aspects gained through experience and observation is the perception of …

Stereo Matching Using A Modified Efficient Belief Propagation In A Level Set Framework, Stephen Goyer Rogers

Dissertations

Stereo matching determines correspondence between pixels in two or more images of the same scene taken from different angles; this can be handled either locally or globally. The two most common global approaches are belief propagation (BP) and graph cuts.

Efficient belief propagation (EBP), which is the most widely used BP approach, uses a multi-scale message passing strategy, an O(k) smoothness cost algorithm, and a bipartite message passing strategy to speed up the convergence of the standard BP approach. As in standard belief propagation, every pixel sends messages to and receives messages from its four neighboring pixels in EBP. Each …

Folate Receptor-Targeted Delivery Of Small Interfering Rna To Cancer Cells, Yilin Zhang

Dissertations

The vitamin folic acid (folate, FA) has been extensively explored as a targeting ligand to deliver a variety of diagnostic/prognostic/therapeutic agents into various tumors through the assistance of its receptor – the folate receptor (FR). FR is over-expressed in many types of human cancer and can mediate internalization of FA-conjugates through an endocytic pathway. The discovery of small interfering RNA (siRNA), which is cable of inducing potent gene silencing in a sequence-specific manner, provides an excellent molecular tool to suppress aberrant gene expression in malignancies, and therefore siRNA has the potential to revolutionize cancer therapeutics.

A Psychometric Investigation Of The Young Adult Social Behavior Scale (Yasb), Michelle Rene Augustin

Dissertations

Aggressive behavior is a serious public health concern that has resulted in several problems in contemporary society. Despite a considerable body of literature on human aggression, both popular and scientific, a focus on overt physical aggression has obscured other forms of aggression. As a result, considerably less is known about other, more subtle forms of aggression, such as relational aggression. Moreover, research on relational aggression, particularly among older adolescents and adults, has been hindered by the lack of psychometrically sound measures. Research in this area would be enhanced by the availability of such a measure, facilitating comparison of data across …

Geological And Ichthyological Investigations Into Palaeodrainage Hypothesis For The Tennessee River, Andrea Karen Persons

Dissertations

The course of the ancestral Tennessee River has been debated in both the geological and biological literature for over 100 years. Several of the proposed courses for the ancestral Tennessee place its course across the state of Mississippi. Geochemical analysis of sedimentary rocks in the Pascagoula River basin supports these hypotheses suggesting that the rocks in the Pascagoula basin were derived from the Highland Rim of Tennessee and northern Alabama, while geochemical analysis of rocks from the Pearl River basin point to deposition from a mixture of sources including the ancestral Mississippi River and perhaps the ancestral Tennessee. To delve …

Acetate Causes Alcohol Hangover Headache In Rats., Christina R Maxwell, Rebecca Jay Spangenberg, Jan B Hoek, Stephen D Silberstein, Michael L Oshinsky

Department of Neurology Faculty Papers

BACKGROUND: The mechanism of veisalgia cephalgia or hangover headache is unknown. Despite a lack of mechanistic studies, there are a number of theories positing congeners, dehydration, or the ethanol metabolite acetaldehyde as causes of hangover headache.

METHODS: We used a chronic headache model to examine how pure ethanol produces increased sensitivity for nociceptive behaviors in normally hydrated rats.

RESULTS: Ethanol initially decreased sensitivity to mechanical stimuli on the face (analgesia), followed 4 to 6 hours later by inflammatory pain. Inhibiting alcohol dehydrogenase extended the analgesia whereas inhibiting aldehyde dehydrogenase decreased analgesia. Neither treatment had nociceptive effects. Direct administration of acetate …

A Degradation Model For Solid Oxide Fuel Cell Anodes Due To Impurities In Coal Syngas, Fatma Nihan Cayan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Solid Oxide Fuel Cells (SOFCs) offer great promise as a clean and efficient alternative to conventional power generation technologies. A major advantage of SOFCs in comparison to other fuel cell types is that they can be operated directly on a wide variety of fuels including biogas, hydrocarbon fuels and coal-derived synthesis gas (syngas). SOFC operating on coal syngas is an especially attractive prospect given the abundant coal resources in the world. However, coal syngas usually contains various impurities such as phosphorus, arsenic, zinc, sulfur, mercury, selenium, and vanadium which affect the performance and durability of SOFCs. At low impurity concentrations, …

Structure And Expression Of Two Nuclear Receptor Genes In Marsupials: Insights Into The Evolution Of The Antisense Overlap Between The Α-Thyroid Hormone Receptor And Rev-Erbα, Brandon C. Rindfleisch, M. Scott Brown, John L. Vandeberg, Stephen Munroe

Biological Sciences Faculty Research and Publications

Background: Alternative processing of α-thyroid hormone receptor (TRα, NR1A1) mRNAs gives rise to two functionally antagonistic nuclear receptors: TRα1, the α-type receptor, and TRα2, a non-hormone binding variant that is found only in mammals. TRα2 shares an unusual antisense coding overlap with mRNA for Rev-erbα (NR1D1), another nuclear receptor protein. In this study we examine the structure and expression of these genes in the gray short-tailed opossum, Monodelphis domestica, in comparison with that of eutherian mammals and three other marsupial species, Didelphis virginiana, Potorous tridactylus and Macropus eugenii, in order to understand the evolution and regulatory …
