Directional Analysis And Filtering For Dust Storm Detection In Noaa-Avhrr Imagery, Swapna Janugani

Open Access Theses & Dissertations

In this research, we propose spatio-spectral processing techniques for the detection of dust storms in 5-band NOAA-AVHRR imagery. The research is mainly focused on locating the dust sources and automatically finding the transport direction of the dust storm. Previous methods that use simple band math analysis have produced promising results but have some drawback in producing consistent results when low SNR images are used. Moreover, in seeking to automate the dust storm detection, the presence of clouds in the vicinity of the dust storm creates a challenge in being able to distinguish these two types of image texture. Our research …

Reduced Dimensionality Hyperspectral Classification Using Finite Mixture Models, Vikram Jayaram

Open Access Theses & Dissertations

Classification of HSI data is a challenging problem for two main reasons. First, with limited spatial resolution of HSI sensors and/or the distance of the observed scene, the images invariably contain pixels composed of several materials. It is desirable to resolve the contributions of the constituents from the observed image without relying on high spatial resolution images. Remote sensing cameras have been designed to capture a wide spectral range motivating the use of post-processing techniques to distinguish materials via their spectral signatures. Secondly, available training data for most pattern recognition problems in HSI processing is severely inadequate. Under the framework …

Riding The Borderlands: The Negotiation Of Social And Cultural Boundaries For Rio Grande Valley And Southwestern Motorcycling Groups, 1900-2000, Gary L. Kieffner

Open Access Theses & Dissertations

This Dissertation presents an analysis and interpretation of particular aspects of the social, cultural, and ideological history of motorcycling in the US-Mexican Borderlands from 1900 to 2000. It is based on interviews with historical correspondents, archival and other documents as well as thirty years of participant reflection during which the author was immersed in biker culture. The motorcycle served as a vehicle for personal and group identity, resistance, and liberation. Issues related to identity, gender, race, marginalization and resistance, imagery, and rhetoric become clearer when considering the perspective of riders. This study surveys interactive processes that occurred between historic motorcyclists, …

The Distinctiveness Effect In Fingerprint Identification: How The Role Of Distinctiveness, Information Loss, And Informational Bias Influence Fingerprint Identification, Jessica L. Marcon

Open Access Theses & Dissertations

Fingerprint misidentification has become a concern for legal professionals, especially after the high profile misidentification of Brandon Mayfield as the Madrid train bomber and the first fingerprint related DNA exoneration of Stephen Cowans. The current studies examined how humans perceive the distinctiveness of fingerprints, whether distinctiveness effects found in face perception research are evident in fingerprint identification, and whether there are conditions under which the distinctiveness effect can be eliminated. Experiment 1 examined the distinctiveness effect and information loss, while Experiment 2 investigated the distinctiveness effect and its interaction with information loss and informational bias. In Experiment 1, results showed …

Spatio-Temporal Ecg Analysis For Localization Of Arrhythmias Using Precordial Ecg Leads And 128-Lead Systems, Eduardo Morales

Open Access Theses & Dissertations

A novel and state-of-the-art approach for the analysis of cardiac arrhythmias is proposed. Currently, the analysis of the electrocardiogram is only performed in the time-domain. The proposed method improves the electrocardiogram analysis by adding spatial properties. The spatial properties added to the electrocardiogram allow for the analysis of specific regions inside the human heart where cardiac arrhythmias are suspected to have occurred. In this Dissertation, the concept of electrocardiography was extended using advanced bioelectromagnetism theory. In concrete, the multiple dipole model of the human heart was used to extend the concept of electrocardiography from a temporal analysis to a spatial-temporal …

The Effects Of Psychopathy And Machiavellianism On Cognitive Dissonance, Ashley Anne Murray

Open Access Theses & Dissertations

Psychopathic traits include a lack of guilt, a lack of remorse, callousness and antisocial behaviors such as impulsivity and aggression. The current study examined the effects of psychopathic traits as measured by the Psychopathic Personality Inventory - Revised: Short Form (PPI-R: SF; Lilienfeld & Widows, 2005) and the Levenson Primary and Secondary Psychopathy Scales (LPSP; Levenson, Kiehl, & Fitzpatrick, 1995), and of Machiavellianism (MACH), as measured by the MACH-IV (Christie & Geis, 1970), on cognitive dissonance in a sample of 164 participants. The induced compliance paradigm of cognitive dissonance was implemented by instructing each participant to complete a boring task …

Characterization Of The Behavioral And Neurochemical Effects Of Nicotine Withdrawal In Adolescent And Adult Rats., Luis Alberto Natividad

Open Access Theses & Dissertations

Previous studies have demonstrated that the behavioral effects of nicotine withdrawal are lower in adolescent versus adult rats. However, the neurochemical mechanisms that mediate these developmental differences are presently unclear. Much work has shown that nicotine reward is mediated via enhanced dopamine neurotransmission in the mesolimbic pathway which originates in the ventral tegmental area (VTA) and terminates in several forebrain structures including the nucleus accumbens (NAcc). More recently, studies have shown that nicotine withdrawal produces a decrease in NAcc dopamine transmission, an effect that is believed to serve as a neurochemical marker of withdrawal in adult rodents. The goal of …

Towards More Reliable Extrapolation Algorithms With Applications To Organic Chemistry, Jaime Nava

Open Access Theses & Dissertations

One of the main objectives of science and engineering is to predict the results of different situations. For example, in Newton's mechanics, we want to predict the positions and velocities of different objects (e.g., planets) at future moments of time.

In this Thesis, as a case study, we take the problem of predicting the properties of new chemical substances. One of the main objectives of chemistry is to design new molecules (and, more generally, new chemical compounds) which are useful for various practical tasks. New substances have already resulted in new materials for buildings and for spaceships, new explosives and …

The Effect Of Facial Resemblance On Alibi Credibility And Final Verdicts, Claudia Ochoa

Open Access Theses & Dissertations

The purpose of this study was to examine an extra-legal variable that may affect the credibility of a defendant and the alibi corroborator's testimonies. In this study, the facial appearance of the alibi corroborator was manipulated to resemble the defendant or the trial judge to different degrees using facial morphing software. Participants serving as mock jurors provided verdicts for a trial summary and rated the credibility of an alibi corroborator. It was hypothesized that as the facial resemblance shared between an alibi corroborator and a defendant increased, the less credible the alibi corroborator's testimony would be perceived, resulting in an …

Three-Dimensional Electronics Packaging Integration Of Stereolithography And Direct Print, Misael Navarrete

Open Access Theses & Dissertations

Traditional placement of components and routing in electronic devices has been constrained to two dimensions in printed circuit board technology. Routing of electrical signals in these devices has been extended to two and half dimensions by virtue of additional routing layers which are connected through vertical vias (i.e. four layer printed circuit boards or CMOS chips with seven layers of metal routing), however, truly three dimensional off axis component placement and routing have not yet been explored. Solid freeform fabrication provides the means of creating a dielectric substrate suitable for these electronics with sockets for components and channels for interconnect. …

Clarence X?: The Black Nationalist Behind Justice Thomas's Constitutionalism, Stephen F. Smith

Journal Articles

The opinions of Justice Thomas reflect a jurisprudence that is uniquely his own. His well-known commitment to textualism and originalism combines with a weak commitment to stare decisis on constitutional questions. This often puts Thomas at odds with Justice Scalia and other Justices who are far more willing to defer to precedents with which they disagree. The most distinctive aspect of Thomas's jurisprudence, however, involves cases of particular concern to black Americans. In these cases, his originalism and textualism are powerfully supplemented by another -ism—namely, "black nationalism."

Throughout his tenure, Justice Thomas has repeatedly explored the implications of controversial rulings …

International Human Rights Law And Security Detention, Douglass Cassel

Journal Articles

This article analyzes the grounds, procedures, and conditions required by International Human Rights Law for preventive detention of suspected terrorists as threats to security. Such detention is generally permitted, provided it is based on grounds and procedures previously established by law; is not arbitrary, discriminatory, or disproportionate; is publicly registered and subject to fair and effective judicial review; and the detainee is not mistreated and is compensated for any unlawful detention. In Europe, however, preventive detention for security purposes is generally not permitted. If allowed at all, it is permitted only when a State in time of national emergency formally …

The Effectiveness Of Biodiversity Law, John Copeland Nagle

Journal Articles

The Endangered Species Act (ESA) has generated a heated debate between those who believe that the law has succeeded and those who believe that the law has failed. The resolution to that debate depends upon whether the law’s stated purposes or some other criteria provide the basis for judging a law’s effectiveness. Meanwhile, since the enactment of the ESA in 1973, biodiversity protection has received growing attention in the nations of southeastern Asia. So far, the law has been much less effective in protecting Asian biodiversity from habitat loss, commercial exploitation, and other threats, yet southeastern Asia’s biodiversity law has …

From Nationalization Of Islam To Privatization Of Nationalism: Islam And Turkish National Identity, Tamer Balci

History Faculty Publications

This article traces the origins of various proposals to nationalize Islam in Turkey. The initial Turkish proposals failed because none of them had a feasible philosophical base to facilitate the co-existence of Islam and secularism. Aside from the previous studies on the nationalization of Islam, this article carries the topic to the Cold War by arguing that the Turkish-Islamic Synthesis was the last stage on the nationalization of Islam. Since TIS had no vision to alter the official ideology, Kemalism, and it claimed the compatibility of Islam, nationalism, secularism as well as Kemalism, it fulfilled the need of a national …

The Relationship Of Group Support, Majority Status, And Interpersonal Dependency In Predicting Intimate Partner Violence, Mary Elisabeth Gray

Dissertations and Theses

One of the most common community responses to intimate partner violence is batterer intervention programs (BIPs), which are aimed at ending perpetrators' violent behavior. Unfortunately, however, the success rates of BIPs are questionable (Aldarondo, 2002; Gondolf, 2002) and we do not know what factors of the program facilitate decreases in abusive behavior when this does occur. Specifically, it is unknown whether and how individual characteristics interact with intervention group dynamics to facilitate change. To better understand this gap in the literature, this study investigated the relationship between social support, group majority-minority status, and interpersonal dependency in predicting intimate partner violence. …

Generating Sustainable Weight Loss: Investigating The Efficacy Of A Behavioral Based Weight Loss Intervention, Michael James Bordieri

Theses

Two thirds of Americans are overweight or obese. Traditional obesity interventions (e.g. drug therapy, diets, behavior therapy) generate moderate short-term weight loss but have little evidence of long-term weight maintenance. The cultural phenomenon of "yo-yo dieting" mirrors empirical findings which suggest that weight loss, albeit demanding, is a far easier process to target than weight maintenance. The present study sought to evaluate the efficacy of an acceptance based behavioral intervention designed to generate improvements in psychological health and quality of life in obese and overweight adults as well as encourage gradual and sustainable weight loss. The therapy package combined the …

Relationship Between Principal Leadership Actions And Business And Social Justice Cultures In Schools, Daniel Reyes-Guerra

Electronic Theses and Dissertations 2000 - 2009

This study detected and explored the existence of two proposed school cultures, the use of leader actions by principals, and the relationships between them, of a sample of 42 public schools in Southeast Florida. A quantitative non-experimental design was used, guided by eight research questions. One instrument, the BSJQ, was created for the purposes of detecting school normative cultures and another, the SLQ, was refined and used to detect principal leader actions. The existence of Business and Social Justice cultures was confirmed, and three latent cultures of Standards Performance, Democratic Community and Equity Curriculum were discovered. Of the schools participating, …

Resource Assessment Of Southeast Florida As Related To Ocean Thermal Energy, Anna E. Leland

Electronic Theses and Dissertations 2000 - 2009

An assessment of the thermal resource in the Straits of Florida was performed to estimate the Ocean Thermal Energy Conversion (OTEC) potential. Direct measurements of the temperature profile across the Florida Straits were taken from nearshore Southeast Florida to the Exclusive Economic Zone boundary along four evenly spaced transects perpendicular to Florida's Southeast coast, spanning 160 km. Along the southern transects in summer, nearshore cold and warm water resources meet or exceed the average 20ÀC temperature difference required for OTEC. In winter, the nearshore average DT of 17.76ÀC can produce 59-75% design net power and 70-86% in spring with DT …

Relative Prefrontal Cortex Surface Area In Pan Troglodytes And Homo Sapiens And Its Implications For Cognitive Evolution, Ian D. George

Electronic Theses and Dissertations 2000 - 2009

The human prefrontal cortex (PFC) is associated with complex cognitive behaviors such as planning for the future, memory for serial order, social information processing and language. Understanding how the PFC has changed through time is central to the study of human neural evolution. Here we investigate the expansion of the PFC by measuring relative surface area of the PFC in Pan troglodytes and Homo sapiens. Magnetic resonance images (MRI's) from 8 preserved chimpanzee brains (3 male and 5 female adults) were segmented and measured. The results of this study indicate that there are gross anatomical differences between the chimpanzee and …
