Position Transformation: A Location Privacy Protection Method For Moving Objects, Dan Lin, Elisa Bertino, Reynold Cheng, Sunil Prabhakar

Computer Science Faculty Research & Creative Works

The expanding use of location-Based services has profound implications on the privacy of personal information. in this paper, we propose a framework for preserving location privacy based on the idea of sending to the service provider suitably modified location information. Agents execute data transformation, and the service provider directly processes the transformed dataset. Our technique not only prevents the service provider from knowing the exact locations of users, but also protects information about user movements and locations from being disclosed to other users who are not authorized to access this information. We also define a privacy model to analyze our …

Development And Verification Of A Laboratory For The Emissions Testing Of Locomotive Engines, Michael R. Shahan

Graduate Theses, Dissertations, and Problem Reports (ETD)

West Virginia University (WVU) currently has a Transportable Emissions Laboratory capable of measuring the exhaust constituents produced by a heavy duty diesel engine. The laboratory has the capability of measuring the exhaust constituents from a partial exhaust stream of a locomotive diesel engine. As the field of locomotive engine emissions testing broadens, it has become desirable for WVU to develop a laboratory that is capable of sampling the gaseous exhaust constituents produced by a locomotive engine from a raw, undiluted gas stream, in tandem with a partial flow dilution tunnel system for particulate matter. This document provides the design philosophy …

Hemodynamics Of Intracranial Aneurysms: Factors That May Influence Occurrence, Francisco Adolfo Pino Romainville

Graduate Theses, Dissertations, and Problem Reports (ETD)

The formation and growth of intracranial aneurysms are partly attributed to various hemodynamic factors, such as the wall shear stress and pressure. However, the exact nature of the hemodynamic variables responsible for triggering aneurismal growth is still unknown. The conclusions drawn by various studies in this regard are found to be speculative and sometimes ambiguous. This issue is further investigated in the present work using some new insight gained from passive scalar dispersion in the blood flow for realistic aneurysm geometries. Intracranial aneurysms are best visualized using selective catheter angiogram technique where a contrast agent added to the blood flow …

The Partisan Politics That Led To The Spanish-American War, Donald E. Thompson Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis explores how partisan politics played a major role in leading the United States into the Spanish-American War. With the unprecedented economic depression that began in 1893, many American politicians exploited a rebellion in Cuba to distract Americans from their own financial problems. During the administration of Grover Cleveland politicians from all political parties supported American intervention in Cuba on behalf of the rebels. This show of support for the Cuban rebels by politicians was designed to rally the American public around a common cause and highlight the difference between them and the unpopular President Cleveland who opposed American …

Ecology Of A Central Appalachian White-Tailed Deer Herd At Low Density, Shawn M. Crimmins

Graduate Theses, Dissertations, and Problem Reports (ETD)

White-tailed deer (Odocoileus virginianus) are the most abundant big game species in North America and serve as the dominant herbivore in the majority of the Appalachian region. Despite the abundance of research conducted on this species, relatively little is known of the ecology of white-tailed deer occurring at low densities. Our study population experienced a 75% decline in population density and a three-fold increase in habitat disturbance via timber harvests between 2002 and 2005. From May 2006 to April 2008 I examined the home-range, survival, and herbivory patterns of a central Appalachian white-tailed deer herd that has recently experienced both …

Optimization Of Bit Interleaved Coded Modulation Using Genetic Algorithms, Raghu Chaitanya Doppalapudi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Modern wireless communication systems must be optimized with respect to both bandwidth efficiency and energy efficiency. A common approach to achieve these goals is to use multi-level modulation such as quadrature-amplitude modulation (QAM) for bandwidth efficiency and an error-control code for energy efficiency. In benign additive white Gaussian noise (AWGN) channels, Ungerboeck proposed trellis-coded modulation (TCM), which combines modulation and coding into a joint operation. However, in fading channels, it is important to maximize diversity. As shown by Zehavi, diversity is maximized by performing coding and modulation separately and interleaving bits that are passed from the encoder to the modulator. …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Tourism has been playing an increasingly important role in the economic development and promotion for the state of West Virginia. However, how tourism resources are spatially distributed across all the states' 55 counties and have not received much attention. This study could be among the first of its kind in West Virginia to create an inventory database for 21 types of major outdoor recreation/nature-based tourism resources, and spatially examine their distribution across counties. The quantity of tourism resources is determined by measuring their actual size, length, or number, and the quality of the resources is determined by using the Analytic …

Motivation In Sport: Bridging Historical And Contemporary Theory Through A Qualitative Approach, Daniel J. Leidl

Graduate Theses, Dissertations, and Problem Reports (ETD)

From intrinsic and extrinsic motivation to attributions and goal orientation, theory and study related to motivation in sport abound. However, theorists such as Adler (Adler, 1998), Frankl (1984), and Maslow (Maslow, 1962) detail broader motivational frameworks that focus on a human impulse to derive meaning and purpose by extending beyond the self. While such theories take prominent positions within psychology, there applicability to sport has seemingly been overlooked. In an effort to explore more traditional motivational constructs in sport, a qualitative analysis of elite lacrosse coaches (n=7) was conducted. Through semi-structured interviews, coaches shared their motivation to coach and how …

The focus group consisted of …

Complex Stimulus Control In Humans: Merging Functional And Equivalence Classes, Harold E. Lobo

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation investigated the merging of functional and equivalence classes produced by training responding to either simple or conditional discriminations. Experiment 1 targeted the acquisition of three three-member equivalence classes featuring class-specific reinforcers and three three-member functional classes each controlling the occurrence of a nonsense vocal response. Four female college students completed testing for the targeted stimulus classes. Two subjects demonstrated class-consistent emergent responding, but only one of them maintained class-consistent responding across repeated testing. This student withdrew from the experiment before class merging was arranged. Experiment 2 simplified and expedited the procedures for producing independent emergent classes. Four female …

An Examination Of Liability, Duty, And Disclaimers For The Pleasure Horse Industry In West Virginia And Other States, Jennifer L. Poling

Graduate Theses, Dissertations, and Problem Reports (ETD)

In an effort to protect equine professionals, horse owners, and equestrian participants from liability associated with injury, 45 of 50 states have enacted Equine Activity Statutes. Many of these statutes vary widely with regard to the individuals and types of activities that are afforded protection. Under most state laws there are many requirements for horse owners and equine professionals regarding disclosure of dangerous behaviors in the horse, past medical problems, soundness issues, and other types of risks to potential buyers and handlers. Facility operators and owners are also required to make reasonable efforts to repair dangerous equipment and/or warn visitors …

Emotional, Cognitive, And Family Systems Mediators Of Children's Adjustment To Interparental Conflict, Gregory M. Fosco, John H. Grych

Psychology Faculty Research and Publications

Emotional, cognitive, and family systems processes have been identified as mediators of the association between interparental conflict and children's adjustment. However, little is known about how they function in relation to one another because they have not all been assessed in the same study. This investigation examined the relations among children's exposure to parental conflict, their appraisals of threat and blame, their emotional reaction, and triangulation into parental disagreements. One hundred fifty ethnically diverse 8- to 12-year-old children and both of their parents participated in the study. Comparisons of 3 models proposing different relations among these processes indicated that they …

Self-Incrimination And The Epistemology Of Testimony, Michael S. Pardo

Cardozo Law Review

The Supreme Court's limitation of the privilege against self-incrimination to evidence of a testimonial nature has been controversial. The doctrinal reliance on a distinction between physical and testimonial evidence has proven difficult to apply in practice, and it has been criticized as being descriptively inaccurate, analytically incoherent, and normatively indefensible. This article offers a defense of the distinction on epistemological grounds. The philosophical focus on testimony as a source of knowledge provides some insight into what makes testimony distinct as an epistemic source. These considerations are used to provide a coherent and principled way to distinguish what evidence to treat …

Interference Effects Due To Projectile Target Nucleus Scattering In Single Ionization Of H₂ By 75-Kev Proton Impact, Jason S. Alexander, Aaron C. Laforge, Ahmad Hasan, Z. S. Machavariani, M. F. Ciappina, R. D. Rivarola, Don H. Madison, Michael Schulz

Physics Faculty Research & Creative Works

Doubly differential cross sections (DDCSs) for single ionization of molecular hydrogen by 75-keV proton impact have been measured and calculated as a function of the projectile scattering angle and energy loss. Interference structures are observed in the scattering angular dependence of the DDCSs, which disappear, however, at electron speeds near the projectile speed. The comparison to our calculations shows that the projectile-target nucleus interaction plays a central role. Furthermore, our data suggest that for a given scattering angle, ionization favors well-defined molecular orientations.

Generalization Effects Of Social Story Interventions For Individuals With Asperger's Disorder, Jennifer Alphonso Abraham

Dissertations

Social Stories™ (Gray, 2004) is a relatively new intervention designed to teach appropriate skills to individuals diagnosed with Autism Spectrum Disorders. Although there is preliminary evidence of the effectiveness of Social Stories it has typically been implemented in one target setting. As a result, there are little data to support whether or not the effects of Social Stories will generalize to other settings. The current study examined the effectiveness of Social Stories for increasing appropriate behaviors exhibited by four children diagnosed with Asperger's Disorder. Generalization effects across settings were assessed using a typical Social Story (Train and Hope) format and …

Dissertations

The objectives of this study were to examine racial differences in the sleep distribution of 4- to 5-year-old children, to assess the relationship between napping and psychosocial functioning, and to determine if there are racial differences in the relationship between napping and psychosocial functioning. The sleep behavior of 67 children (52.2% non-Hispanic White; 55.2% male) 4 to 5 years old from a community sample was assessed through caregiver-report and actigraphy. Psychosocial functioning was examined through caregiver-report and laboratory tasks designed to assess aspects of behavioral and emotional functioning. Results indicate that, compared to White children, Black children nap significantly more …

The Role Of Racial Attitudes And Identity In Black Client-White Counselor Dyads, Tara Michelle Ferguson

Dissertations

The therapeutic alliance has become an important area of investigation in the psychotherapy literature due to its demonstration of a moderate and consistent relationship with therapy outcomes. Some researchers have suggested that barriers to alliance formation may exist in cross-ethnic dyads due to different worldviews, race related socialization experiences, and racial attitudes. Although past research has indicated that racial identity and attitudes played a role in predicting various counseling processes, no studies in this area have examined their influence in actual counseling dyads. The purpose of the present study was to investigate the role of Black racial identity and attitude …

Photopolymerization And Characterization Of Thiol-Enes And Thiourethanes, Qin Li

Dissertations

Compared to conventional acrylic monomer systems, thiol-ene photopolymerization, an efficient click process leading to the formation of dense and uniform molecular networks, has several distinct advantages including relative insensitivity to oxygen inhibition, high monomer conversion and low shrinkage. Although there has been a revival of interest in thiol-enes in the past 6 years, the structure-property relationship of these networks has not been explored in detail. For future applications, thiol-enes with higher shelf-life stability and glass transition temperatures need to be used. Sulfur containing urethanes, thiourethanes and dithiourethanes are a class of widely used materials due to their distinct properties such …

A Comparison Of Reading Interventions Based On Preference To Reading Interventions Identified By Brief Experimental Analysis, Debborah Eda Smyth

Dissertations

The available literature on children's acceptability of interventions is rather sparse and offers little support for the link between acceptability and effectiveness (e.g., Foxx & Jones, 1978; Shapiro & Goldberg, 1986; Turco & Elliot, 1990). The present study compared the effects of treatment preference to treatment effectiveness using a brief experimental analysis to select skill-based oral reading fluency interventions. The use of a brief experimental analysis (BEA) (Daly, Martens, Hamler, Dool, & Eckert, 1999) has been demonstrated to be an effective procedure for selecting oral reading interventions. However, the studies on brief experimental analysis to date have not examined student …
