Delamination Detection In Concrete Using Disposable Impactors For Excitation, Anjali Narendra Patil

Theses and Dissertations

Delaminations in concrete bridge decks result primarily from corrosion of the reinforcing bars (or rebar). This corrosion leads to volumetric expansion of the rebar. When the rebar expands, concrete cracks, and there is a localized separation of the concrete cover from the underlying concrete. Impact-echo testing is an effective technique to map delaminations on concrete bridge decks. However, mapping speed is limited by necessary retrieval of the impactor for traditional tests. To achieve higher scanning speeds, it is advantageous to use both a non-contact measurement (air-coupled impact-echo) and disposable-impactor excitation. Disposable impactors have the potential advantage of achieving greater deck …

On The Demand To Incorporate Shari'a Law Into Uk Law, Mayada Serageldin

Theses and Dissertations

The origin of this thesis lay in the emergence of a minority group of ‘religious’ activists in London, England. The purpose of this group was to establish “Shari’a Zones” in pockets of Waltham Forest and Tower Hamlets, wherein certain acts would be prohibited and Shari’a law would be enforced. This led to an examination of the theological and religious beliefs of this small and much marginalized section of the British Muslim community. What became apparent is that this group prescribed to a view of Islam, and shariah law in particular, which is incongruent with the provisions of human rights law. …

Theses and Dissertations

Using Cognitive Evaluation Theory, this research evaluated the impact non-monetary extrinsic incentives in the form of department t-shirts had on the intrinsic motivation of Virginia career and volunteer firefighters. Intrinsic motivation was measured using the Work Extrinsic and Intrinsic Motivation Scale (WEIMS). The survey was administered to a randomly selected sample of firefighters. Data was analyzed using multiple regression analysis. Results suggested that the department t-shirt did not have a statistically significant impact on intrinsic motivation of both career and volunteer firefighters. Additionally, this study suggested that volunteer firefighters did not perceive salary as an inequitable reward. This was exhibited …

An Architecture For Coexistence With Multiple Users In Frequency Hopping Cognitive Radio Networks, Ryan K. Mclean

Theses and Dissertations

The radio frequency (RF) spectrum is a limited resource. Spectrum allotment disputes stem from this scarcity as many radio devices are con confined to a fixed frequency or frequency sequence. One alternative is to incorporate cognition within a configurable radio platform, therefore enabling the radio to adapt to dynamic RF spectrum environments. In this way, the radio is able to actively observe the RF spectrum, orient itself to the current RF environment, decide on a mode of operation, and act accordingly, thereby sharing the spectrum and operating in more flexible manner. This research presents a novel framework for incorporating several …

Electronic Characteristics Of Rare Earth Doped Gan Schottky Diodes, Aaron B. Blanning

Theses and Dissertations

The Schottky barrier height (SBH) was measured on GaN based diodes with three different dopant types; Gd, Er and Yb. Two methods were used to determine the SBH. The first method was the Juergen Werner method to evaluate the I-V characteristics. The calculated SBH of the diodes using this method was 1.41 ± 0.20eV, 1.71 ± 0.25eV and 1.75 ± 0.28eV for the Gd-, Er- and Yb-doped diodes respectively. It was observed that using an ad-hoc effective Richardson constant value of 0.006Axcm^-2xK^-2 to calculate the SBH rendered results that were in no greater than 2% disagreement (neglecting …

Stepwise logistical regression analysis ascertained the ability of chosen variables to predict individuals' preparedness. The rate of prepared individuals was lower if they were between the ages of 18 to 54 years, when compared to the reference age group of 65 …

Does Time Matter? An Examination Of Sentence Length, Time Served And Probation Outcomes, Michael P. Mcgrath

Theses and Dissertations

There remains some uncertainty as to whether or not probation supervision can influence the behaviour of offenders as intended and thereby protect the public. Within the growing body of probation literature is support for a number of theoretically relevant variables and probation outcomes (Morgan, 1993; Gendreau, Little & Goggin, 1996). Some of the probation studies include a measure of time (Sims & Jones, 1997; Green & Winik, 2010), although it has never been exclusively studied in probation research. In the studies that do include a time measure, sentence length is the most frequently used and is often related to failure …

Perceptions Of Legal Policy And Sex Offender Treatment, Kirsten Sierra Engel

Theses and Dissertations

Sex offender policy, treatment, and public perception are greatly intertwined in the numerous policies in place regarding sex offenders. These policies tend to reflect the underlying perceptions and myths about sex offenders than the reality of sexual offenses and treatment. These perceptions have also had a role in shaping psychological treatment of sex offenders through enacted policies and public support, or dissent, for community treatment centers, half-way houses, or residency restriction laws. With the sizeable potential impact of the public's perceptions of these issues, examination of their perceptions of sex offenders, sex offender policies, and sex offender treatment, and whether …

Modeling Approaches, Physiological Responses, And Climate Change: How Good Is "Good Enough?", Nicole Kish

Theses and Dissertations

Predicting spatial and temporal patterns in the responses of organisms and ecosystems to climate change has emerged as a major focus of macrophysiological research, with much work centered on the impacts of temperature. A potential difficulty lies in the observation that measures of 'habitat' such as air, land and sea surface temperature often differ greatly from the body temperature actually experienced by organisms, as the latter drives reproduction and survival. As a result, it is unclear how often these simple measurements of habitat are 'good enough' for predicting physiological stress in the field, and when more complicated methods are needed. …

Developing Hybrid Near-Space Technologies For Affordable Access To Suborbital Space, Brian David Badders

Theses and Dissertations

High power rockets and high altitude balloons are two near-space technologies that could be combined in order to provide access to the mesosphere and, eventually, suborbital space. This "rockoon" technology has been used by several large budget space programs before being abandoned in favor of even more expensive, albeit more accurate, ground launch systems. With the increased development of nano-satellites and atmospheric sensors, combined with rising interest in global atmospheric data, there is an increase in desire for affordable access to extreme altitudes that does not necessarily require the precision of ground launches.

Development of hybrid near-space technologies for access …

The sample consisted of 31 male sex offenders who had all served prison sentences for a sexual offense and were involved in mandated outpatient treatment at 1 of 3 private, community−based clinics. The participants were diverse in regard to ethnicity, level of education, and marital status; they had …

Brand Reputation And Product Recall, Anne Meike Eilert

Theses and Dissertations

Every year, firms make numerous announcements to recall products that are deemed unsafe or defective. These recalls pose a significant threat to a firm's brand reputation. The strong, negative reactions of consumers and the media to the recalls initiated by Toyota in 2010 show how fragile brands are in the wake of a recall. Firms spend a great amount of resources on building strong brands and it is unclear how such brands influence the firm's decision to announce a recall and the consumer's decision to return the recalled product. The objective of this dissertation is to shed some light on …

Gender And Programming: A Comparison Of Program Availability And Participation In U.S. Prisons For Men And Women, Courtney A. Crittenden

Theses and Dissertations

The current study examines the state of prison programming across the U.S. and whether availability of and participation in prison programs varies by gender and other key factors such as the interaction effects of race and gender, self-identified needs, and facility-level characteristics. Using Morash, Rucker, and Haarr's (1994) study, the last major study comparing prison programming for men and women in U.S. prisons, as a guide, I explore the current state of prison programming using national-level survey data. The results indicate that gender does indeed matter for both prison programming availability and participation with women having more programs available to …

An Assessment Of Technology Adoptability In Sugarcane Burning Smoke Plume Mitigation, Sara Flecher

Theses and Dissertations

The adverse health effects of sugarcane burning emissions on surrounding communities are well documented. Sugarcane farmers in Louisiana, a major sugarcane producing state with 385,000 acres dedicated to sugarcane farming throughout, attempt to mitigate the effects of burn emissions by estimating the characteristics of the resultant smoke plume using meteorological variables as parameters. The current mitigation method designed by the LSU AgCenter, the American Sugar Cane League, and the Louisiana Department of Agriculture and Forestry is a manual process requiring the tedious look-up of atmospheric variables from multiple sources and physically drawing a predicted smoke plume on a paper map, …

Sex Offenders' Perceptions Of North Dakota's Sex Offender Policies, Mariah Dawn Laver Juanto

Theses and Dissertations

Registered sex offenders in North Dakota were interviewed regarding their experiences with being on the registry. Results from the coded transcripts indicate that offenders felt the registry made finding housing and employment more difficult. Additionally, participants reported feeling the registry negatively impacted their ability to be involved in community organizations and impacted how they interacted with others, including forming supportive relationships. Participants also completed surveys, assessing general psychological symptoms, general stress levels, and demographic information, including registration requirement information. No significant relationships between sex offenders' registry requirements and psychological symptoms were found. Conclusions and implications for future research are discussed.

Exploitation Of Rf-Dna For Device Classification And Verification Using Grlvqi Processing, Donald R. Reising

Theses and Dissertations

This dissertation introduces a GRLVQI classifier into an RF-DNA fingerprinting process and demonstrates applicability for device classification and ID verification. Unlike MDA/ML processing, GRLVQI provides a measure of feature relevance that enables Dimensional Reduction Analysis (DRA) to enhance the experimental-to-operational transition potential of RF-DNA fingerprinting. Using 2D Gabor Transform RF-DNA fingerprints extracted from experimentally collected OFDM-based 802.16 WiMAX and 802.11 WiFi device emissions, average GRLVQI classification accuracy of %C greater than or equal to 90% is achieved using full and reduced dimensional feature sets at SNR greater than or equal to 10.0 dB and SNR greater than or equal to …

White, Black, And Blue: The Battle Over Black Police, Professionalization, And Police Brutality In Birmingham, Alabama, 1963-1979, Bryan Kessler

Theses and Dissertations

This thesis explores the municipal politics and race relations in Birmingham, Alabama, from October 1963 to November 1979. While Birmingham is a centerpiece of the traditional Civil Rights Movement for its staging of the Bull Connor and Martin Luther King, Jr., confrontation in 1963, there has been little examination of the continuing struggles between the black and white communities in the years after the media spotlight. Of particular concern are the battles between the black community, white power structure, and the city’s police department over black policemen, professionalization and modernization, and police brutality. The changing role and tactics of black …
