Forensic Analysis of Ink on Documents Using Direct Analyte-Probed Nanoextraction Coupled Techniques

Description: Analzying questioned documents in a nondestructive nature has been an issue for the forensic science community. Using nondestructive techniques such as video spectral comparator does not give reliable information due to the variations in gray or color levels that are distinguished differently by analysts. Destructive techniques such as chromatography give dependable, qualitative and quantitative, information but involves altering the evidentiary value of these questioned documents. The paradox … more

Simulink® Based Design and Implementation of a Solar Power Based Mobile Charger

Description: Electrical energy is used at approximately the rate of 15 Terawatts world-wide. Generating this much energy has become a primary concern for all nations. There are many ways of generating energy among which the most commonly used are non-renewable and will extinct much sooner than expected. Very active research is going on both to increase the use of renewable energy sources and to use the available energy with more efficiency. Among these sources, solar energy is being considered as the most a… more

Programmatic Geographical Depictions in Large-Scale Jazz Ensemble Works: Major Works by Gil Evans and Chuck Owen and a New Work by Aaron Hedenstrom

Description: This dissertation explores the creative process in large-scale jazz ensemble works that are programmatic in depicting geographical locations. This is achieved through analyses of Gil Evans's Sketches of Spain, Chuck Owen's River Runs: A Concerto for Jazz Guitar, Saxophone, & Orchestra, and Aaron Hedenstrom's Sketches of Minnesota. Each work is examined using five analytical categories: orchestration, large-scale form, harmonic/melodic development, programmatic framework, and use of featured sol… more

Impact of Grit on Performance After Mastery- or Performance-Oriented Feedback

Description: Grit and achievement motivation have been predictors of behavior in academia and military settings (Duckworth, Matthews, Peterson, & Kelly, 2007), but to date, research on their effects on sport performance has been limited. Given grit's predictive role in other performance domains, grit may be influential in athletes' long-term goal attainment, interacting with their achievement motives and leading to better performances. Athletes' trait levels of grit may influence how they understand and res… more

Mock Juror Effects of Blame and Conviction in Rape Cases: Do Attitudes, Beliefs, and Contact with Homosexuals Matter?

Description: The current case involves a female rape victim. Research has shown the level of victim blaming can be elevated if the victim is a lesbian woman compared to a heterosexual woman. Mock jurors’ responses to personality trait questionnaires (e.g., Belief in a Just World, Attitudes Toward Women, Attitudes Toward Lesbians) and amount of contact they have with homosexual people were employed as predictors of how they would decide victim blaming and perpetrator guilt. Personality trait findings were no… more

Comment peut-on être Persane ou Peruvienne ?: On le devient

Description: Cette analyse littéraire examine les parallèles entre les deux romans Lettres persanes de Montesquieu (1721) et Lettres d'une Péruvienne de Françoise de Graffigny (1747) en se concentrant sur le sort des femmes et leur rébellion contre la claustration. Leurs révoltes transformatrices révèlent une volonté qui refuse et puis transcende les barreaux de leur captivité pour vivre librement. La philosophie de Simone de Beauvoir (1908-1986) personnifie leurs luttes pour devenir et exister, ce qui se … more

Continuous Combinatorics of a Lattice Graph in the Cantor Space

Description: We present a novel theorem of Borel Combinatorics that sheds light on the types of continuous functions that can be defined on the Cantor space. We specifically consider the part X=F(2ᴳ) from the Cantor space, where the group G is the additive group of integer pairs ℤ². That is, X is the set of aperiodic {0,1} labelings of the two-dimensional infinite lattice graph. We give X the Bernoulli shift action, and this action induces a graph on X in which each connected component is again a two-dimen… more

Interfacial Electrochemistry of Cu/Al Alloys for IC Packaging and Chemical Bonding Characterization of Boron Doped Hydrogenated Amorphous Silicon Films for Infrared Cameras

Description: We focused on a non-cooling room temperature microbolometer infrared imaging array device which includes a sensing layer of p-type a-Si:H component layers doped with boron. Boron incorporation and bonding configuration were investigated for a-Si:H films grown by plasma enhanced chemical deposition (PECVD) at varying substrate temperatures, hydrogen dilution of the silane precursor, and dopant to silane ratio using multiple internal reflection infrared spectroscopy (MIR-IR). This study was then … more

Social Anxiety and Non-Medical Prescription Stimulant Use Among College Students

Description: Current evidence suggests that non-medical prescription stimulant (NMPS) use is on the rise, particularly among college students. Identifying individuals at risk for regular and problematic use is a critical step towards the development of effective intervention efforts. A growing body of work has noted that individuals with elevated levels of social anxiety (SA) or social anxiety disorder are at an enhanced risk for developing substance use problems, including NMPS use disorder. Despite the re… more

Ours is the Kingdom of Heaven: Racial Construction of Early American Christian Identities

Description: This project interrogates how religious performance, either authentic or contrived, aids in the quest for freedom for oppressed peoples; how the rhetoric of the Enlightenment era pervades literatures delivered or written by Native Americans and African Americans; and how religious modes, such as evoking scripture, performing sacrifices, or relying upon providence, assist oppressed populations in their roles as early American authors and speakers. Even though the African American and Native Amer… more

Highly Stretchable Miniature Strain Sensor for Large Dynamic Strain Measurement

Description: This thesis aims to develop a new type of highly stretchable strain sensor to measure large deformation of a specimen subjected to dynamic loading. The sensor was based on the piezo-resistive response of carbon nanotube(CNT)/polydimethysiloxane (PDMS) composites thin films, some nickel particles were added into the sensor composite to improve the sensor performance. The piezo-resistive response of CNT composite gives high frequency response in strain measurement, while the ultra-soft PDMS matri… more
