An Assessment And Analysis Of Using Dedicated Short-Range Communications (Dsrc) Technology For Incident Detection On Rural Freeways, Joseph D. Crabtree

University of Kentucky Doctoral Dissertations

This report describes an assessment of using dedicated short-range communications(DSRC) technology to perform travel time monitoring and automated incident detectionon a segment of rural freeway. The assessment used the CORSIM traffic simulation toolto simulate traffic and incidents on a segment of rural freeway. Output data from thesimulation was subjected to post-processing to produce the "probe and beacon" data thatwould be produced by a DSRC-based system. An incident detection algorithm wasdeveloped, which used a travel time threshold and a counter. Travel times exceeding thethreshold incremented the counter, while travel times below the threshold decrementedthe counter (unless it was at zero). An …

Challenges In Estimating Size And Conservation Of Black Bear In West-Central Florida, Joshua Hager Brown

University of Kentucky Master's Theses

The Greater Chassahowitkza Ecosystem black bear (Ursus americanus floridanus) population of west-central Florida is likely to be the smallest documented population of the species. It has experienced almost no recruitment since 1997 and exhibits behavior that appears to be a response to human activities. The local diet is dominated by the fruit of saw palmetto and sabal palm, species that exhibit patchy distributions and irregular mast production. These food supplies are often separated by busy highways that have killed 6 bears since 1997, 21% of known individuals. Motion-activated camera surveys suggest that the bear population is declining in this rapidly …

Probabilistic Databases And Their Applications, Wenzhong Zhao

University of Kentucky Doctoral Dissertations

Probabilistic reasoning in databases has been an active area of research during the last twodecades. However, the previously proposed database approaches, including the probabilistic relationalapproach and the probabilistic object approach, are not good fits for storing and managingdiverse probability distributions along with their auxiliary information.The work in this dissertation extends significantly the initial semistructured probabilistic databaseframework proposed by Dekhtyar, Goldsmith and Hawkes in [20]. We extend the formal SemistructuredProbabilistic Object (SPO) data model of [20]. Accordingly, we also extend the SemistructuredProbabilistic Algebra (SP-algebra), the query algebra proposed for the SPO model.Based on the extended framework, we have designed and implemented …

Diagnosis Of Condition Systems, Jeffrey Ashley

University of Kentucky Doctoral Dissertations

In this dissertation, we explore the problem of fault detection and fault diagnosis for systems modeled as condition systems. A condition system is a Petri net based framework of components which interact with each other and the external environment through the use of condition signals. First, a system FAULT is defined as an observed behavior which does not correspond to any expected behavior, where the expected behavior is defined through condition system models. A DETECTION is the determination that the system is not behaving as expected according to the model of the system. A DIAGNOSIS of this fault localizes the …

Sexual Tensions Of Post-Empire, Katherine M. Franke

Faculty Scholarship

In this essay Katherine Franke examines two contemporary cites in which state efforts to eradicate the traces of empire and to resurrect an authentic post-colonial nation have produced sexual subjects that serve as a kind of existential residue and reminder of a demonized colonial past and absence. Looking first at post-colonial Zimbabwe, Franke argues that President Mugabe's aggressively homophobic policies have played a key role in fortifying his leadership as authentically African and post-colonial.

Franke then turns to current efforts by the Mubarak government in Egypt to publically prosecute men for having sex with men. The Mubarak government has used …

Beyond The Book: Promoting Effective Research, Jana M. Borchardt

The Christian Librarian

In the past library professionals have primarily collected and provided access to materials; however, this paper will argue that we must now go beyond access or "Beyond the Book. " One way to do this is to learn about the information search process and then assume a new and more assertive role as a "research advisor. " We need to change our patrons 'expectations so that they see us as knowledgeable about sources, yes, but also as experts on effective research as a process of discovery. Three relevant information search process models are covered, as well as the way people …

Optimal Design Of Engineering Systems Using Mpi-Enabled Genetic Algorithm, S. D. Rajan, D. T. Nguyen, M. D. Deshpande, L. Harrell

Civil & Environmental Engineering Faculty Publications

The focus of this paper is on the development and implementation of a genetic algorithm (GA)-based software system using message passing interface (MPI) protocol and library. A customized form of simple GA used in previous research [1-4] is parallelized. This MPI-enabled version is used to find the solution to finite element based design optimization problems. Results show that an almost linear speedup is obtained on homogenous hardware cluster and, with proper reworking of the software, on heterogeneous hardware cluster.

Virtual Personal Assistants In A Pervasive Computing World, John F. Bradley, Brian R. Duffy, Gregory O'Hare, Alan Martin, Bianca Schoen-Phelan

Conference papers

Computing paradigms are constantly evolving-from mainframe to desktop, and on to ubiquitous computing. With a wide variety of devices, each with varying constraints, it would be quite difficult to develop services that would operate in a uniform manner across all platforms. With this in mind we offer an agent based solution. Agent attributes of autonomy, adaptability and mobility make them highly suitable for use in pervasive computing environments. Agent Chameleons illustrates a framework for Virtual Personal Assistants (VPA) for the information age. This paper briefly outlines some of the technologies and concepts that underpin the functionality of a VPA.

Teachers' Receptions Of Facilitators And Barriers To Inclusion: A Regional Survey, Hillary Kretz-Harvey

Theses

This study examined teachers' perceptions of facilitators needed to include students with special needs. The Teachers' Opinions of Inclusive Education Needs Survey (TOIENS) was developed for this study in order to examine teachers' perceptions of facilitators to inclusion. Results found that teachers identified material and personnel supports, preservice and inservice training, and environmental/classroom features as all similarly necessary. Discrepancies were found, however, between identified facilitators and the availability of them. Personnel supports were generally considered to be available in the school districts, but several necessary material supports, training, and environmental/classroom features were considered to be unavailable.

An Analysis Of The Consistency Of Brand Color Reproduction In Print Packaging And Magazine Advertising, Seunga Kang Ha

Theses

Brand color is one way to represent the identity of the corporation and for the company to advertise itself. The purpose of brand color is to make customers perceive the color, recognize the brand, and ultimately buy products manufactured by the corporation. However, it is not easy to produce the same color through different print media applications because of different processes of color reproduction technology. In the print industry, corporations have controlled brand color tolerance to insure its consistency. However, there is some question as to how the print industry actually performs in maintaining this tolerance through reproduction. The goal …

A Physics-Based Model Of Sic-Based Mesfets, Sankha Mukherjee

Theses

Silicon Carbide (SiC) has been investigated as an alternative material to Silicon (Si) for enhancing the power-handling capability of semiconductor devices for simultaneous high-temperature and high frequency applications. Its high thermal conductivity, high bandgap, low permittivity, high saturation velocity, moderate mobility, material hardness and chemical inertness make it a prime candidate for power electronics, heat and light sensors, and MEMS applications. The MESFET is the most viable power transistor based on SiC. The performance of SiC MESFETs is limited by trapping and thermal effects. A physics-based analytical model of the SiC MESFET incorporating trapping and thermal effects is reported. The …

Multiprocessor Dsp Implementation Of The Jpeg 2000 Codec, Scott Mayne

Theses

The transition to JPEG2000 from other image formats such as standard JPEG offers im proved compression and image quality, yet has not been widely adopted in practice. This is mainly due to the complexity of the JPEG2000 algorithm. Standard JPEG uses the Discrete Cosine Transform (DCT) and Huffmann encoding to achieve its compression, whereas JPEG2000 uses the wavelet transform and arithmetic encoding. Due to the wide acceptance of JPEG, there are processors such as Equator Technology's BSP-15 digital signal processor (DSP) that have been designed with features specifically for JPEG appli cations. For some of the current digital printing applications …

Art Tales: Art As A Communicator Of New York State Folklore, Erin Claire Tobin

Theses

This thesis project focuses on the use of folktales as a starting point to explore texture and pattern. The artist was striving to create a visual communication of folktales. Using physical layers in the paintings to create spatial depth as well as to express the idea of the building of layers as a metaphor for the story of life, the artist engages the viewer to relate this to the idea that culture is built from many different layers of stories over time.

Optimization And Simulation Of Just-In-Time Supply Pickup And Delivery Systems, Keng Hoo Chuah

University of Kentucky Doctoral Dissertations

A just-in-time supply pickup and delivery system (JSS) manages the logistic operations between a manufacturing plant and its suppliers by controlling the sequence, timing, and frequency of container pickups and parts deliveries, thereby coordinating internal conveyance, external conveyance, and the operation of cross-docking facilities. The system is important to just-in-time production lines that maintain small inventories. This research studies the logistics, supply chain, and production control of JSS. First, a new meta-heuristics approach (taboo search) is developed to solve a general frequency routing (GFR) problem that has been formulated in this dissertation with five types of constraints: flow, space, load, …

Global Change, Domestic Policy, And Life Course Influences On Perceptions Of Health Equity Among Older Cubans, James Lester Schwar

University of Kentucky Doctoral Dissertations

Cubas provision of free health services to the entire population via neighborhood-based family doctors produced dramatic health gains and achieved a relative state of health equality. Since 1989, however, the termination of Soviet trade, a grave economic crisis, intensification of the US embargo, welfare reductions, and population aging have placed Cubas health successes and elder care services in jeopardy. Little independent research, though, has focused on the influence of post-Cold War circumstances on citizen attitudes about health programs and resources targeting Cubas older population. This research examined global and domestic factors since 1989 that have most influenced perceptions of the …

Generalized Analytical Model For Rf Planar Inductors Using A Segmentation Technique, Marie Yvanoff

Theses

The planar coil inductor has become a very critical circuit component in RF mixed signal application where it can reside either on the package or in the chip. However, there is no clear methodology to accurately analyze the behavior of the inductor over a broad range of frequencies and for obtaining a particular physical layout for a required value of inductance. At present, it has been done by full wave solvers, approximate quasistatic analysis, and lumped element equivalent circuits, each with its own advantages and limitations. This work presents an analytical model based on a segmentation method in conjunction with …

Automatic Error Recovery Using P3 Response Verification For A Brain-Computer Interface, Samuel A. Inverso

Theses

A brain-computer interface (BCI) is an augmentative communication mechanism that does not rely on peripheral nerves or muscles. Current BCIs are error prone and slow with error rates of 10 to 30% and transmission rates of 10-25 bits/min, however, error recovery and correction in BCI has largely been neglected. The focus of this thesis is the development of a method to automatically recover errors in BCI using the P3 brain signal for response verification. The existence of the P3 signal in responses to controlled goal items is shown in an evoked potential BCI used to control items in a virtual …
