Structural And Functional Studies Of Synaptic Enzymes, Eun Jeong Lim Jan 2006

Structural And Functional Studies Of Synaptic Enzymes, Eun Jeong Lim

University of Kentucky Doctoral Dissertations

Thimet oligopeptidase (TOP, EC 3.4.24.15) and neurolysin (EC 3.4.24.16) are zincdependent metallopeptidases that metabolize small bioactive peptides. The two enzymes share60 % sequence identity and their crystal structures demonstrate that they adopt nearly identicalfolds. They generally cleave at the same sites, but they recognize different positions on somepeptides, including neurotensin, a 13-residue peptide involved in modulation of dopaminergiccircuits, pain perception, and thermoregulation.On the basis of crystal structures and previous mapping studies, four residues(E469/R470, M490/R491, H495/N496, and R498/T499, TOP residues listed first) in thesubstrate-binding channel appear positioned to account for differences in specificity. TOPmutated to the neurolysin residues at all four …

Dynamic Freeway Travel Time Prediction Using Single Loop Detector And Incident Data, Jingxin Xia

University of Kentucky Doctoral Dissertations

The accurate estimation of travel time is valuable for a variety of transportation applications such as freeway performance evaluation and real-time traveler information. Given the extensive availability of traffic data collected by intelligent transportation systems, a variety of travel time estimation methods have been developed. Despite limited success under light traffic conditions, traditional corridor travel time prediction methods have suffered various drawbacks. First, most of these methods are developed based on data generated by dual-loop detectors that contain average spot speeds. However, single-loop detectors (and other devices that emulate its operation) are the most commonly used devices in traffic monitoring …

The Role Of Book Type In The Retention Of Novel Vocabulary Among Children African American Children With Vocabulary Deficits, Sherri Lovelace Jan 2006

The Role Of Book Type In The Retention Of Novel Vocabulary Among Children African American Children With Vocabulary Deficits, Sherri Lovelace

University of Kentucky Doctoral Dissertations

Research has shown that cultural differences and the lack of experiences in the lives of young children can affect the rate of vocabulary development. In particular, children from different ability, socioeconomic status, and culturally and linguistically diverse groups are considered at risk for later academic achievement because their home experiences and word usage may be incongruent with that of the mainstream school cultural environment. Therefore, it has been suggested that to decrease the gap between children in need of vocabulary development and their typically achieving peers, instruction in vocabulary should systematically provide information about words and their uses. Thus, the …

Comparison Of Celp Speech Coder With A Wavelet Method, Sriram Nagaswamy

University of Kentucky Master's Theses

This thesis compares the speech quality of Code Excited Linear Predictor (CELP, Federal Standard 1016) speech coder with a new wavelet method to compress speech. The performances of both are compared by performing subjective listening tests. The test signals used are clean signals (i.e. with no background noise), speech signals with room noise and speech signals with artificial noise added. Results indicate that for clean signals and signals with predominantly voiced components the CELP standard performs better than the wavelet method but for signals with room noise the wavelet method performs much better than the CELP. For signals with artificial …

The Smart Bookshelf, Danny Sylvester Crasto Jan 2006

The Smart Bookshelf, Danny Sylvester Crasto

University of Kentucky Master's Theses

The smart bookshelf serves as a test-bed to study environments that are intelligently augmented by projector-camera devices. The system utilizes a camera pair and a projector coupled with an RFID reader to monitor and maintain the state of a real world library shelf. Using a simple calibration scheme, the homography induced by the world plane in which book spines approximately lie is estimated. As books are added to the shelf, a foreground detection algorithm which takes into account the projected information yields new pixels in each view that are then verified using a planar parallax constraint across both cameras to …

The Universal Media Book, Shilpi Gupta Jan 2006

The Universal Media Book, Shilpi Gupta

University of Kentucky Master's Theses

We explore the integration of projected imagery with a physical book that acts as a tangible interface to multimedia data. Using a camera and projector pair, a tracking framework is presented wherein the 3D position of planar pages are monitored as they are turned back and forth by a user, and data is correctly warped and projected onto each page at interactive rates to provide the user with an intuitive mixed-reality experience. The book pages are blank, so traditional camera-based approaches to tracking physical features on the display surface do not apply. Instead, in each frame, feature points are independently …

Manipulation Of Thinness And Restricting Expectancies: Further Evidence For A Causal Role Of Thinness And Restricting Expectancies In The Etiology Of Eating Disorders, Agnes M. Annus Jan 2006

Manipulation Of Thinness And Restricting Expectancies: Further Evidence For A Causal Role Of Thinness And Restricting Expectancies In The Etiology Of Eating Disorders, Agnes M. Annus

University of Kentucky Master's Theses

Eating disorder expectancy theory proposes a causal role for expectancies for reinforcement from thinness. The authors conducted an experimental test of that hypothesis. Undergraduate college women (N = 154) were randomized to either a psychoeducational control of proven effectiveness or an experimental manipulation of thinness and restricting expectancies. Participants in each condition attended three experimental sessions and one, follow-up session, each one week apart. For both groups, body dissatisfaction, disordered eating, purging frequency, and binge eating frequency declined over the course of the study. In addition, the thinness expectancy manipulation produced greater declines in thinness expectancies, body dissatisfaction, and purging …

An Intelligent System For The Defect Inspection Of Specular Painted Ceramic Tiles, Jinhua Li Jan 2006

An Intelligent System For The Defect Inspection Of Specular Painted Ceramic Tiles, Jinhua Li

University of Kentucky Master's Theses

Product visual inspection is still performed manually or semi automatically in most industries from simple ceramic tile grading to complicated automotive body panel paint defect and surface quality inspection. Moreover, specular surfaces present additional challenges to conventional vision systems due to specular reflections, which may mask the true location of objects and lead to incorrect measurements. Some sophisticated optical inspection methods have already been developed for high precision surface defect inspection in recent years. Unfortunately, most of them are highly computational. Systems built on those methods are either inapplicable or costly to achieve real-time inspection. This thesis describes an integrated …

Detection Of Malingered Mental Retardation, Lili Odom Graue Jan 2006

Detection Of Malingered Mental Retardation, Lili Odom Graue

University of Kentucky Master's Theses

The 2002 Supreme Court decision (Atkins vs. Virginia, 536 U. S. 304), prohibiting the execution of mentally retarded persons, may potentially increase malingering of mental retardation (MR). There is limited research addressing the detection of feigned MR. The present study compared results from tests of intelligence, adaptive functioning, legal/courtroom knowledge, and psychiatric and neurocognitive feigning to determine how effectively these instruments discriminate between MR participants and community volunteers asked to either approach the test honestly (CVH group) or feign, or malinger, MR (CVM group). CVMs suppressed their IQ scores sufficiently to appear MR. CVMs overestimated deficits on individuals with genuine …

The Gap Between What Taxpayers Want And What Tax Professionals Think They Want: A Reexamination Of Client Expectations And Tax Professional Aggressiveness, Teresa Stephenson Jan 2006

The Gap Between What Taxpayers Want And What Tax Professionals Think They Want: A Reexamination Of Client Expectations And Tax Professional Aggressiveness, Teresa Stephenson

University of Kentucky Doctoral Dissertations

The purpose of this dissertation is to resolve an apparent conflict between the services that tax preparers provide and the tax preparation services taxpayers seek. Some literature demonstrates that tax professionals equate client advocacy with taking aggressive tax positions and minimizing taxes. Other literature suggests taxpayers seek to increase accuracy and reduce the probability of tax audit when they hire a tax professional. This difference is an "expectation gap."The methodology employed to examine this issue is a survey of tax professionals at various levels of expertise. This survey asks tax preparers what they believe motivates their clients to seek professional …

Exploiting Sparseness Of Communication Patterns For The Design Of Networks In Massively Parallel Supercomputers, Timothy Ian Mattox

University of Kentucky Doctoral Dissertations

A limited set of Processing Element (PE) pairs in a parallel computer cover the internal communications of scalable parallel programs. We take advantage of this property using the concept of Sparse Flat Neighborhood Networks (Sparse FNNs). Sparse FNNs are network designs that provide single-switch latency and full wire bandwidth for each specified PE pair, despite using relatively few network interfaces per PE and switches that have far fewer ports than there are PEs. This dissertation discusses the design problem, runtime support, and working prototype (KASY0) for Sparse FNNs. KASY0 not only demonstrated the claimed properties, but also set world records …

Optimal Phase Measuring Profilometry Techniques For Static And Dynamic 3d Data Acquisition, Veeraganesh Yalla Jan 2006

Optimal Phase Measuring Profilometry Techniques For Static And Dynamic 3d Data Acquisition, Veeraganesh Yalla

University of Kentucky Doctoral Dissertations

Phase measuring Profilometry (PMP) is an important technique used in 3D data acquisition. Many variations of the PMP technique exist in the research world. The technique involves projecting phase shifted versions of sinusoidal patterns with known frequency. The 3D information is obtained from the amount of phase deviation that the target object introduces in the captured patterns. Using patterns based on single frequency result in projecting a large number of patterns necessary to achieve minimal reconstruction errors. By using more than one frequency, that is multi-frequency, the error is reduced with the same number of total patterns projected as in …

Molecular Mechanisms That Mediate Metastasis Suppressor Activity Of Nm23-H1, Qingbei Zhang Jan 2006

Molecular Mechanisms That Mediate Metastasis Suppressor Activity Of Nm23-H1, Qingbei Zhang

University of Kentucky Doctoral Dissertations

Metastasis is the spread of cancer cells from the primary tumor to distant sites. It is the most dangerous attribute of cancer, and also the principle cause of cancerrelated morbidity and mortality. Metastasis suppressor genes are a group of genes that suppress tumor metastasis without significant effect on tumorigenicity. NM23 was the first identified metastasis suppressor gene, and loss of its expression is a frequent hallmark of metastatic growth in multiple cancers (e.g. melanoma, carcinomas of breast, stomach and liver). NM23-H1 possesses at least three enzymatic activities, including nucleoside diphosphate kinase (NDPK), histidine kinase (hisK), and a more recently described …

Today’S Dot And The Quest For More Accountable Organizational Structures, Lenahan O'Connell, Juita-Elena (Wie) Yusuf, Merl Hackbart, Donald L. Hartman, Candice Wallace, Doug Kreis

Kentucky Transportation Center Research Report

This study investigates the impact of DOT organizational structures on effective transportation planning and performance. A review of the 50 state DOT authorizing statutes and DOT organizational charts found minimal differences in organizational structures among the states. However, 37 states have quasi-independent commissions (sometimes called boards, or councils.) A statistical analysis showed that the commission states have higher Government Performance Project (GPP) scores than the non-commission states. The analysis suggested that effective commissions avoid having members represent geographical regions and political parties and avoid giving the commission the power to select the director of the DOT. In addition the states …
