We utilize the Semantic Web technologies not only for integrating, repurposing and classification of multi-source clinical data, but also to construct a distributed environment for information sharing, and collaboration online. Service Oriented Architecture (SOA) is used to modularize and distribute reusable services in a …

The Germination Ecology And Composition Of The Indigenous Seeds Of Cyprus Conglomeratus: A Sand Dune Binder, Sheikha Saeed Amer Al Neyadi

Theses

Cyperus conglomeratus is among few species that tolerate the instability of sand dunes and its low nutrients. This species tolerates grazing animals and sand burial. It is considered as a good fodder for both domestic and wildlife animals. It has the potential to fix sand dunes. In addition, a preliminary observation indicated the presence of high contents of oil in the seeds. Despite the ecological importance of C. conglomeratus, little information is available about germination behaviour and seed composition. The present study assessed the dormancy, germination requirement, tolerance to salinity and drought during germination stage, the impact of dormancy regulation …

Malignant Melanoma Metastatic To The Thyroid Gland: A Case Report And Review Of The Literature., Brian Kung, Md, Saba Aftab, Bs, Moira D. Wood, Md, David Rosen, Md

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

The thyroid gland is a relatively uncommon site for a secondary malignancy; even less common is a case of malignant melanoma metastatic to the thyroid. We describe the case of a 68-year-old man who presented with a neck mass in the posterior triangle. Fine-needle aspiration biopsy (FNAB) identified the mass as a malignant melanoma. The patient had had no known primary skin melanoma. He underwent a left modified radical neck dissection, and the mass was discovered to be a positive lymph node. Postoperatively, he declined to undergo radio- and chemotherapy. Eighteen months later, he returned with a diffusely enlarged thyroid. …

Developing Sustainable Spacecraft Water Management Systems, Evan A. Thomas, David M. Klaus

Mechanical and Materials Engineering Faculty Publications and Presentations

It is well recognized that water handling systems used in a spacecraft are prone to failure caused by biofouling and mineral scaling, which can clog mechanical systems and degrade the performance of capillary-based technologies. Long duration spaceflight applications, such as extended stays at a Lunar Outpost or during a Mars transit mission, will increasingly benefit from hardware that is generally more robust and operationally sustainable overtime. This paper presents potential design and testing considerations for improving the reliability of water handling technologies for exploration spacecraft. Our application of interest is to devise a spacecraft wastewater management system wherein fouling can …

Flocking In The Time-Dissonance Plane, Adam James Wilson

Publications and Research

This paper describes a technique for the sonification of an idealized model of the flocking behavior of birds, fish, and insects. Flocking agents are represented by pitches that move through time to produce chords of variable dissonance. The objective of each agent is to move toward more consonant chord formations with other agents. The output of the sonification is intended to provide material for use in musical composition.

A Symbolic Sonification Of L-Systems, Adam James Wilson

Publications and Research

This paper describes a simple technique for the sonification of branching structures in plants. The example is intended to illustrate a qualitative definition of best practices for sonification aimed at the production of musical material. Visually manifest results of tree growth are modelled and subsequently mapped to pitch, time, and amplitude. Sample results are provided in symbolic music notation.

An Eigenanalysis And Synthesis Of Unitary Operators Used In Quantum Computing Algorithms, Steven Randall Hutsell

Dissertations and Theses

In this work we tackle the challenge of designing quantum unitary operators which represent solutions to optimization problems. We start with a novel method which combines an evolutionary algorithm known as an Evolution Strategy (ES) with a method to randomly generate unitary operators. With this new method, a quantum operator is represented for the first time using real-valued vectors and can be "evolved" or designed to meet certain target criteria. This criteria could be the solution to an optimization problem. With the ability to evolve quantum operators, we attempt to evolve various known single and multi-qubit quantum gates as well …

Silent Subjects: Silence In Theories Of Subjectivity, Nikki Ann Agee

Open Access Theses & Dissertations

Postmodern theories describe human subjectivity as fragmented. (Faigley 12). Unlike Enlightenment thinkers, who theorized the Cartesian subject as an autonomous, stable, rational self with "privileged insight into its own processes" (111), postmodern theorists "decisively [reject] the primacy of consciousness and instead [have] consciousness originating in language, arguing that the subject is an effect rather than a cause of discourse" (Faigley 9).

The idea that language constructs who subjects are, how they are, and who they may and may not become is very powerful, for it suggests subjects cannot consciously know themselves apart from language. Self-knowledge results from social, institutional, and …

Hybrid Method: Algebraic/Inverse Radon Transform For Region Of Interest Reconstruction Of Computed Tomography Images, Marco A. Barrera

Open Access Theses & Dissertations

Computed tomography is one of the most rapidly advancing method in modern medical imaging, because of is relatively low cost and outstanding quality. The main shortcoming of the method is the relatively high dose of radiation used. Consequently, considerable efforts have been made to obtain good image reconstructions from fewer projections or from using lower intensity beams (hence, noisier data). It has been known for decades that a scan with high intensity beams and large number of projections (typically, 180-360 for a planar image) will lead to a very good image reconstruction via an Inverse Radon Transform (IRT), but the …

Temperature-Induced Phenomena In Systems Of Magnetic Nanoparticles, Abdul Wazed Bhuiya

Open Access Theses & Dissertations

Magnetic nanoparticle ensembles have received a lot of attention, stemming in part from their current and potential applications in biomedicine and in the development of high-density magnetic storage media. Key to the functionality of these systems are microscopic structures and mechanisms that make them exhibit unique properties and behave differently from their bulk counterparts.

We studied microscopic structures and processes that dictate macroscopic properties, behavior and functionality of magnetic nanoparticle ensembles. As the temperature T strongly influences the magnetic behavior of these systems, we studied temperature dependent magnetic properties using AC-susceptibility and DC-magnetization measurements carried out over a broad range …

Two-Dimensional Gravity Modeling Of The Rattlesnake Springs Watershed, Carlsbad Caverns National Park, New Mexico, Nikolay D. Boykov

Open Access Theses & Dissertations

A series of non-invasive geophysical investigations at the Rattlesnake Springs part of Carlsbad Caverns National Park, New Mexico, were performed in an effort to better delineate the watershed of the springs. The goal of this project is to determine possible locations of fractures and faults that may control the distribution of groundwater that feeds Rattlesnake Springs. Once the water flow paths are identified, the park will be able to better protect Rattlesnake Springs from environmental hazards, such as oil and gas drilling, as well as from upstream water development. As part of this effort I conducted a precision gravity survey …

An Investigation Of Cognitive And Non-Cognitive Variables That Affect Student-Athlete Graduation And Retention, Lisa Diana Campos

Open Access Theses & Dissertations

Colleges and universities continue to be held to accountability measures typically related to student graduation rates. Intercollegiate athletic programs are not immune to such accountability measures. For instance, in recent years the National Collegiate Athletic Association adopted the Academic Progress Rate, which holds institutions accountable for the graduation, retention, and eligibility status of its student-athletes. It is the moral obligation of intercollegiate administrators to ensure student-athletes are receiving a quality education culminating in graduation. The recent climate of higher education makes it critical to examine the variables which influence graduation and retention of student-athletes.

This study examined student-athletes who entered …

“In The Shadow Of A Concrete Forest”: Transportation Politics In Portland, Oregon, And The Revolt Against The Mount Hood Freeway, 1955-1976, Val C. Ballestrem

Dissertations and Theses

In 1955, The Oregon State Highway Department helped usher in the freeway building era in Portland by publishing its plan for 14 modern freeways designed to crisscross the city. A major component of that report was the Mount Hood Freeway, a route designed to pass through southeast Portland, connecting the city to its expanding eastern suburbs. Other freeway routes in the Portland area were given precedence over the Mount Hood Freeway and by 1969, when the route obtained federal interstate status, urban freeways across the nation had become highly controversial. Over the next seven years a struggle ensued pitting those …

Health Prognisis Of Electronics Via Power Profiling, Jonathan Amilcar Cervantes

Open Access Theses & Dissertations

The objective of this research is to investigate a new approach for the early detection of latent defects in electronic devices in the field. Reliability is assessed through the non-traditional approach of recording and evaluating the power profile of electronic devices within a deterministic state of operation. Traditionally, measuring the quiescent current (Iddq) of a device has been employed in manufacturing tests to detect defective parts prior to deployment to the field. However, the monitoring of the deterministic power signature (i.e. boot up or during a self-test routine) has never been exploited to monitor the health of a device in …

Magnitude Of Right-Lateral Offset On The Southern Death Valley Fault Zone From Miocene Volcanic Assemblages, Sabrina Michelle Canalda

Open Access Theses & Dissertations

In this study correlation of Miocene volcanic and sedimentary rocks in southern Death Valley is used to constrain the total amount of slip on the southern Death Valley fault. The tertiary volcanic section near Ibex Pass is correlated to rocks ~35 km to the northwest, in the Wingate Wash region (Luckow et al., 2005). Geochronology by Luckow et al. (2005) in Wingate Wash and the Owlshead Mountains has the region divided into two basic periods: an early interval (~14-13.4Ma), and a later phase (~13-12.5Ma). One date from the volcanic sequence in Ibex Pass has been reported (Calzia, 2000) suggesting that …

The Effectiveness Of Fba-Based Interventions On Social Goals And Behaviors Of A Student At Risk Of E/Bd, Hsin-Ju Chen

Open Access Theses & Dissertations

The purpose of this study was to examine the effectiveness of functional behavioral assessment (FBA) based interventions for improving prosocial goals and behaviors and reducing problem behaviors of a student at risk of emotional and behavioral disorders (E/BD). Specifically, this study was interested in whether the behavioral intervention plans based on the function of behavior had an impact on the student's thought processes impacting prosocial decision making. There was one 11-year-old student who was placed in the behavior intervention class (BIC) participating in this study. Results showed that overall, the student's problem behaviors seemed to decrease during the classroom universal …

Does Type Of Stimulus Influence Task-Irrelevant Evaluative Categorization Processes?, Guadalupe Corral

Open Access Theses & Dissertations

The effect of stimulus type on task-irrelevant evaluative categorization was examined in two separate studies by using the P3 component from event-related brain potentials. The first study presented idiosyncratic stimuli consisting of individuals that were rated by participants as either positive or negative within sequences of pictorial and verbal stimuli. The second study presented sequences of novel and familiar stimuli consisting of previously normed unattractive and neutral individuals. It was hypothesized that pictures would elicit task-irrelevant evaluative categorization processes and so would novel stimuli (relative to words and familiar stimuli, respectively). Task-irrelevance was examined by assessing P3 peak amplitude to …

It's Bigger And Hip-Hop: Richard Wright, Hip-Hop, And Masculinity, Marcos Julian Del Hierro

Open Access Theses & Dissertations

In Native Son, Richard Wright presents a view of the impoverished, inner-city from an insider's perspective, which reflects the anger and hate brewing towards the rest of the nation as a result of living under harsh, isolating conditions. Wright's main character, Bigger Thomas serves as an archetypal ghetto figure both in his attitudes and the treatment he receives from Anglo Americans. Additionally, the reception of Native Son by a majority white reading audience also reflected the voyeuristic thrill of the bourgeoisie when consuming cultural products by African Americans. The selection of Wright's novel into the Book of the Month …

The Pluvial Lake Palomas - Samalayuca Dunes System, Miguel Dominguez Acosta

Open Access Theses & Dissertations

A lacustro-aeolian system formed by the Pluvial Lake Palomas (PLP), the Samalayuca Dunes (SMD) and a connecting aeolian corridor is found in the central Chihuahuan Desert of North America approximately 50 km upwind (SW) of the binational Paso del Norte metroplex. The system is described by its three individual components. They comprise one of the largest paleo-lacustrine (Pleistocene) environments in the Chihuahuan Desert (PLP), one of the largest and least-studied sand seas of North America (SMD), and a newly described and geomorphically heterogeneous aeolian corridor connecting the two.

The Chihuahuan Desert has been a major and underappreciated dust production region …

Characterization Of A Mems Accelerometer For A Highway Health Monitoring Ultra-Low Power Sensor, Karla Cecilia Enriquez

Open Access Theses & Dissertations

With the 2009 American Recovery and Reinvestment Act, government officials recognized the need to implement automated methods that reduce the cost of assessment projects and provide a long-term solution to monitor the structural health of bridges and highways. Although important research exists in the area of non-destructive evaluation, current road health monitoring efforts continue to be costly and time consuming. This Thesis focuses on the characterization of a MEMS accelerometer intended to be the basis of a novel ultra-low power sensing system to remotely asses the condition of highways. The architecture of a sensor prototype built to validate an algorithm …

Appropriate Prosodic Variation Is Valued By Users, Rafael Escalante-Ruiz

Open Access Theses & Dissertations

Spoken dialog systems today do not vary the prosody of their utterances, although prosody is known to have many useful expressive functions. In a corpus of memory quizzes, I identified eleven dimensions of prosodic variation, each with its own expressive function. I identified the situations in which each was used, and how to detect these situations from the dialog context and the prosody of the interlocutor's previous utterance. I implemented the resulting response rules and had 21 users interact with two versions of the system. Overall they preferred the version in which the prosodic forms of the acknowledgments were chosen …

Suswa Volcano, Kenya Rift: Evidence Of Magma Mixing, Na-F Complexing And Eruptions Triggered By Recharge, Vanessa Veronica Espejel Garcia

Open Access Theses & Dissertations

The Cenozoic East African rift system (EARS) is a sequence of grabens, intraplate transforms, accommodation zones, and abundant magmatism. The Central Kenya Peralkaline Province (CKPP) includes a variety of volcanic rocks -trachyte, pantellerite, comendite, phonolite, trachy-basalt, basaltic trachy-andesite, and basalt- which erupted from volcanoes including: Mount Kenya; Eburru and the Greater Olkaria volcanic complexes; Longonot, Menengai, and Suswa volcanoes; and Ndabibi, Elmenteita, and Tandamara mafic volcanic fields. Only two of the volcanoes, Mount Kenya (on the flank of the central graben) and Suswa (the southernmost of the CKPP volcanoes), have phonolites as part of their assemblage.

The evolution of Suswa …

Sustainable Development Extension Plan (Sudex): Community Mobilization Through Proactive Participation And Synergistic Alliance To Alliviate Poverty And Achieve Sustainable Self Sufficiency, Stephen Forbes

Open Access Theses & Dissertations

This Dissertation describes a sustainable development extension plan (Sudex Plan) to help communities in developing countries achieve Goal 1 of the United Nation's Millennium Development Goals (MDG). Goal 1 focuses on reducing poverty and hunger by 50% by the year 2015, but all the MDG are interrelated and one can not be achieved without considering the others, and to attain any is an empty accomplishment without ways to ensure that they can be sustained and continuously improved with the means to pass on the information, knowledge and lessons learned from community to community, generation to generation. The Sudex Plan is …

Three Essays On Chinese Outward Investment, Yan Gao

Open Access Theses & Dissertations

Empirical research and theory development have traditionally focused on Western MNEs. The rise of multinational firms from the emerging markets, particularly MNEs from China has attracted limited empirical research attention. In the current research, I attempt to fill this gap by exploring the entry modes strategies, motivation and government interference when Chinese MNEs go abroad. Early international business theories suggested that firms invest abroad on the basis of possessing certain-firm specific competitive advantages. By leveraging these existing firm-specific advantages overseas, firms are able to generate sufficient returns to overcome the "liability of foreignness". These early FDI theories were largely based …

Top Management Team Heterogeneity, Global Strategic Posture, And Firm Performance: Evidence From Mnes Headquartered Around The World, Adrian Gil

Open Access Theses & Dissertations

This study empirically examines the relationship between top management team (TMT) heterogeneity and firm performance for a sample of multinational enterprises (MNEs) headquartered in 31 countries from across the globe. Utilizing the theoretical perspectives of upper echelons (Hambrick & Mason, 1984) and information processing (Daft, Bettenhausen, & Tyler, 1993; Galbraith, 1973), I hypothesize that global strategic posture, a measure of the intensity of a firm's involvement in the multinational business environment, moderates the relationships between TMT heterogeneity and firm performance. My findings reveal an "enhancing" interaction (Cohen, Cohen, West, & Aiken, 2003: 285-286) between the different TMT heterogeneities investigated and …

Insight Into The Physics Of Rupture: Dynamic Triggering Seismicity, Hector Gonzalez-Huizar

Open Access Theses & Dissertations

Seismic waves can trigger earthquakes and tremor at large distances from the causable event. Dynamic triggering occurs when the surface waves from large earthquakes change the stresses conditions on previously overstressed faults, promoting failure. To understand the causative stresses and environments behind dynamic triggering, we model the change in the stress field that the passing of Rayleigh and Love waves cause on a fault plane of arbitrary orientation relative to the direction of propagation of the waves, and apply a Coulomb failure criterion to calculate the potential of these stress changes to trigger seismicity. We apply our model to three …

Open Access Theses & Dissertations

This study presented a theory in which assistive technology and body kinesthetic helped students understand concepts taught in the regular education classroom. The study included students already identified and diagnosed with a learning disability (LD). The research is based on cognitive theories that state that cognitive development could use alternative representation to have a deeper impact in the way Students with LD process information by activating different parts of the brain that are involved in the learning process. The study included students from 9th thru 12th grades. Students were selected from the ones receiving services from the special education department …

Identification Of Human Gait Using Genetic Algorithm Tuned Fuzzy Logic, Abdallah Abdel-Rahman Hassan Mahmoud

Open Access Theses & Dissertations

Data mining is concerned with the discovery of useful hidden information in large databases. Classification is a data mining task producing rules in which a set of attributes in data predict the value of a class attribute. Classifiers usually produce a large number of rules, most of which are not interesting to the user. Rule interestingness is a decisive factor. However, evaluating rule interestingness is challenging as it involves both objective (data-driven) and subjective (user-driven) aspects.

In this research, a fuzzy genetic algorithm is proposed to discover classification rules that are both accurate and interesting. Continuous attributes are fuzzified so …
