The Use Of A Whole Genome Scan To Find A Genetic Marker For Degenerative Suspensory Ligament Desmitis In The Peruvian Paso Horse, Diane I. Strong

University of Kentucky Master's Theses

Degenerative suspensory ligament desmitis (DSLD) is a debilitating disease of connective tissues seen in many breeds but has become prevalent in the Peruvian Pasohorse. DSLD is believed to be a genetic disorder caused by one primary founder and most likely has a recessive mode of inheritance although a dominant or co-dominant mode of inheritance has not been ruled out.

A genome scan using 259 microsatellite markers was used to test for linkage disequilibrium between one or more markers and DSLD. Two groups of Peruvian Pasohorses were selected from one population including the US and Canada. The only difference between the …

Torque Retention With Polypropylene Bottles, David Garrett Moszak

Theses

Two different case studies were examined to determine how different liner structures or plastic additives affect torque degradation. The first case study examined how torque is affected with and without the use of a zinc stearate plastic additive. The second case study examined how torque retention differs between a synthetic liner and a pulp board backed liner structure. Both torque studies provided a starting point for the application torque range for use in production. The torque studies were used to outline the necessary application torque so that the child resistant closures obtain and maintain the proper torque level over time …

Al2o3 Hosted Attenuated Phase Shift Mask Materials For 157 Nm, Yang Liu

Theses

The Semiconductor Industry Association Roadmap 2003 has put 157 nm optical lithography as the next generation lithography wavelength for the node of 70 nm integrated circuits and below. The small departure from 193 nm puts more challenge on imaging tools and processes. One of the crucial areas is the exploration of thin film optical materials for mask coatings at vacuum ultraviolet (VUV) wavelength. Attenuated Phase Shift Mask (APSM) is one of the optical enhancement technologies pushing critical dimension of lithography to diffraction limits.

Application Of Phenology To Assist In Hyperspectral Species Classification Of A Northern Hardwood Forest, Gretchen Sprehe

Theses

Tree species have unique spectral reflectance patterns that allows them to be both compared to other objects and to other types of trees. Increasing the spectral separation of such images may assist with surveying and forestry inventories. In past studies, most classifications were done with summer leaves, which darken and become very similar shades of green. This study utilized the phenology of trees to investigate how the changing colors of young or senescing leaves may assist in species classification based on aerial images. Images were taken of the Hubbard Brook Experimental Forest, which is mainly dominated by sugar maple (Acer …

Effect Of Added C4-Alcohols On The Structure Of Microemulsion Droplets Measured By Small-Angle Neutron Scattering., Elvis A. Zambrano

Theses

The role of C₄-alcohols (n-butanol, 2-butanol and tert-butanol) in four component microemulsions is studied using neutron scattering. These microemulsions are dispersions of nanoscale droplets consisting of a core of water surrounded by a surfactant-stabilized shell. The particles are suspended in an oil (octane) continuum. The addition of a co-surfactant, such as a short-chain alcohol, modifies the droplet size and structure, as well as the rigidity of the surrounding shell. In this work, we investigate water-in-oil microemulsions employing small-angle neutron scattering (SANS) experiments performed at the NIST Center for Neutron Research. Using this technique, it is possible to probe …

A Multi-Hypothesis Approach For Salient Object Tracking In Visual Surveillance, Filiz Bunyak, Ilker Ersoy, S. R. Subramanya

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a multiple object tracking method for visual surveillance applications is presented. Moving objects are detected by adaptive background subtraction and tracked by using a multi-hypothesis testing approach. Object matching between frames is done based on proximity and appearance similarity. a new confidence measure is assigned to each possible match. This information is arranged into a graph structure where vertices represent blobs in consecutive frames and edges represent match confidence values. This graph is later used to prune and refine trajectories to obtain the salient object trajectories. Occlusions are handled through position prediction using Kalman filter and robust …

Shadow Detection By Combined Photometric Invariants For Improved Foreground Segmentation, Filiz Bunyak, Ilker Ersoy, S. R. Subramanya

Electrical and Computer Engineering Faculty Research & Creative Works

Detection and tracking of moving objects are the essential steps of many video understanding applications such as traffic monitoring, video surveillance and visual event recognition. Moving object detection process segments the scene into foreground (moving) and background regions. Moving cast shadows cause serious problems in this process because they can easily be misclassified as foreground. This misclassification may lead to drastic changes in the shapes of objects or merging of multiple objects. in this paper, we present a method to detect moving cast shadows to improve the performance of moving object detection. the foreground regions are processed in terms of …
