Evaluation Of Environmental Materials As Thermal Witness Materials, Shashank Vummidi Lakshman

Dissertations

New and complex energetic materials are under development for achieving tunable pyrotechnical events for applications such as neutralization of biological weapons, bunker busters and many others. To guide the development of hybrid materials, the pyrotechnical environment they produce requires higher degree of characterization i.e. good description of spatial and temporal temperature distribution.

Temperature measurements in pyrotechnical events are especially challenging, where the temperature of the environment rises more than 2000 K on microseconds to few milliseconds time scale. These environments produce high thermal stress where traditional sensors like thermocouples, optical pyrometers struggle to describe the dynamic changes in the environment. …

Ignition Mechanism In Nanocomposites Thermites, Rayon Williams

Dissertations

Nanocomposite thermites (n-thermites) have been actively investigated for a wide range of potential applications including propellants, explosives, and pyrotechnics. There have been several recent efforts aimed at understanding ignition mechanisms of nanocomposite reactive materials. Although significant progress has been made, ignition mechanisms remain elusive. At the same time, a robust ignition model is required to incorporate these materials in practical energetic formulations. A challenge of this effort is to describe the mechanisms of ignition of n-thermites prepared by Arrested Reactive Milling (ARM) with different stimuli, including heat, spark and impact and also develop a multi-step kinetic model describing different processes …

Synthesis And Characterization Of Metal-Based Reactive Powders, Yasmine Aly

Dissertations

Aluminum added to propellants, explosives, and pyrotechnics, boosts their energy density.

The results of this project did not reveal to the primary investigator what was originally assumed, that …

Re-Evaluating The Criminal Investigative Process: An Empirical Evaluation Of Criminal Investigations In The United States, Jeremiah J. Rayner

Dissertations

Criminal investigations are a fundamental part of the police mission. Little research or scientific inquiry has been considered in this area. However, within the past fifty years there has been some noteworthy research performed. Still, the amount of research undertaken within the realm of the criminal investigative process has not corresponded to the magnitude of its importance in everyday police operations. The research by Chaiken, Greenwood, and Petersillia (1976) on the criminal investigative process was the most substantial contribution to the research of the criminal investigative process in its time. However, in 2001 nearly twenty-five years had passed since the …

Integrating 3d Layered Manufacturing With Photonic Sintering, Precision Machining And Smart Coating Techniques For Rapid Casting Applications, Hemant Bohra

Dissertations

Developments in rapid casting technologies have led to a new era of inclusion of 3D printing. Three-Dimensional (3D) printing provides the flexibility and ease of reproducing a sand mold directly from CAD models, eliminating patterning steps, thus reducing the process time for creating prototypes. In addition to minimizing processing steps, 3D printing provides the advantages of higher precision and the ability to produce complex shaped sand molds, but it simultaneously possesses some limitations and concerns related to throughput, safety and logistics.

This study proposes an alternative method for creating sand molds by introducing a hybrid rapid prototyping approach to overcome …

The State And Civil Society In The Arab Middle East, Stacey E. Pollard

Dissertations

While the notion that civil society organizations can democratize authoritarian regimes from below has become an article of faith among many policy makers and democracy promoters, some area experts warn that practitioners and advocates should not overestimate civil society's democratizing role. This dissertation challenges a large body of scholarship on civil society by arguing that while civil society may constitute a democratic force in any given polity it may also be comprised of less democratic, even radically undemocratic forces as well. Therefore, commensurate with the research yielding that finding, this project argues that on an account of the nature of …

Eliciting Elementary School Students’ Informal Inferential Reasoning Through Storytelling, Dustin Owen Smith

Dissertations

One growing area of research on statistical learning is Informal Inferential Reasoning (IIR). Makar and Rubin (2009) describe IIR as having three components: making and evaluating inferential claims, supporting claims explicitly with data, and attending to the inherent uncertainty present in statistical inference-making. This dissertation study was built around developing a method for providing opportunities for elementary school students (Grades K, 2, and 4) to engage with IIR within the context of stories and storytelling through a method called Storytelling-Questioning. After interacting with and discussing two separate stories, it was found that students of each grade level were able to …

The phenomenological data analysis approach of Moustakas (1994) was utilized to guide the data collection and analysis. Through in-depth, semi-structured interviews, the participants were able to share their …

Mediated Homestyle: Congressional Strategy And Local Press Relations In The 111th House Of Representatives, Michael K. Romano

Dissertations

For over thirty years, research on Congressional behavior has provided evidence of a link between constituent opinions and the ways in which members publically conduct themselves. Homestyle (Fenno, 1978: pg. 32), the way members “cultivate their constituencies,” has emphasized that personal encounters between members and their constituents is an effective strategy for decreasing the level of uncertainty members have about their approval. Homestyle, however, overlooks the fact that members of Congress cannot directly interact with their constituents on a daily basis. The mass media, specifically local media outlets, help legislators by transmitting relevant information about political events and legislators’ actions …

Do Social Communication Skills Mediate The Relation Between Adhd Symptoms And Reltionship Satisfaction?, Erin Clarke Bell

Dissertations

Very few studies have examined adult attention-deficit/hyperactivity disorder (ADHD) and relationship satisfaction. The current study focused on ADHD symptoms, social communication skills, and relationship satisfaction. Based on previous research that provides evidence that individuals with ADHD tend to have more difficulty with both receptive and expressive social communication skills as well as the large amount of evidence that communication is a key component to relationship satisfaction, it was expected that higher ADHD symptoms in one partner of a romantic dyad would relate to less relationship satisfaction. Furthermore, because ADHD is associated with a positive illusory bias (PIB), it was also …

Normative Feedback, Levels Of Narcissism, And Student Evaluations Of A Lecture, Shirley Ann Hodges

Dissertations

Individuals who have narcissistic traits have a tendency to behave more aggressively in both indirect and direct ways, especially when confronted with negative feedback that threatens their self-esteem. Little is known about how trait-level individual differences affect aggression for people who have narcissistic tendencies. Among adults, where direct confrontation is generally discouraged, aggression may be difficult to detect. Rational-appearing aggression is used in the workplace, generally by supervisors toward employees. In some environments, however, including academic environments, 360o feedback is prevalent, with faculty grading student performance and students evaluating faculty in the form of course evaluations. Faculty are held accountable …

Development And Applications Of The Expanded Equivalent Fluid Method, Bharath Kumar Kandula

Dissertations

Ocean acoustics is the study of sound in the oceans. Electromagnetic waves attenuate rapidly in the water medium. Sound is the best means to transmit information underwater. Computational numerical simulations play an important role in ocean acoustics. Simulations of acoustic propagation in the oceans are challenging due to the complexities involved in the ocean environment. Different methods have been developed to simulate underwater sound propagation. The Parabolic-Equation (PE) method is the best choice in several ocean acoustic problems. In shallow water acoustic experiments, sound loses some of its energy when it interacts with the bottom. An equivalent fluid technique was …
