Estimation And Inference For Spatial And Spatio-Temporal Mixed Effects Models, Casey M. Jelsema

Dissertations

One of the most common goals of geostatistical analysis is that of spatial prediction, in other words: filling in the blank areas of the map. There are two popular methods for accomplishing spatial prediction. Either kriging, or Bayesian hierarchical models. Both methods require the inverse of the spatial covariance matrix of the data. As the sample size, n, becomes large, both of these methods become impractical. Reduced rank spatial models (RRSM) allow prediction on massive datasets without compromising the complexity of the spatial process. This dissertation focuses on RRSMs, particularly situations where the data follow non-Gaussian distributions.

Sex Determination Using Discriminant Function Analysis In Hispanic Children And Adolescents: A Lateral Cephalometric Study, Alyssa E. Sprowl

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lateral cephalometric radiographs have been used for years to help diagnose skeletal and dental patterns in Orthodontics. Within the last decade, these radiographs have caught the interest of the department of Anthropology for the identification of gender within the adult and adolescent population. Numerous publications have been made but failed to identify sexual dimorphism in the pre-adolescent population. 303 lateral cephalograms of pre and post Latino adolescence age ranging from 6.5 to 17.9 years old were obtained from University of Nevada, Las Vegas (UNLV) digital database. 25 variables were identified and plotted with all linear and angular measurements transferred into …

Hearing-Aid Safety: A Comparison Of Estimated Threshold Shifts For Gains Recommended By Nal-Nl2 And Dsl M[I/O] Prescriptions For Children, Teresa Y. C. Ching, Earl E. Johnson, Mark Seeto, John H. Macrae

ETSU Faculty Works

Objective: To investigate the predicted threshold shift associated with the use of nonlinear hearing aids fitted to the NAL-NL2 or the DSL m[i/o] prescription for children with the same audiograms. For medium and high input levels, we asked: (1) How does predicted asymptotic threshold shifts (ATS) differ according to the choice of prescription? (2) How does predicted ATS vary with hearing level for gains prescribed by the two prescriptions? Design: A mathematical model consisting of the modified power law combined with equations for predicting temporary threshold shift (Macrae, 1994b) was used to predict ATS. Study sample: Predicted threshold shift were …

The Underlying Physiology Of Arterial Pulse Wave Morphology In Spatial Domain, Nzerem F. Egenti, Alozie H. Nkechi

Applications and Applied Mathematics: An International Journal (AAM)

Cardio-vascular events are among the world’s leading causes of morbidity and mortality. Most postulates suppose that culinary delights can be implicated in incidences of cardio-vascular diseases. This school of thought holds well in many respects. Much as the truistic value of the said school is acknowledged, we conceived of physiological disposition as an endogenous dominant factor in the events being considered, whereas culinary measures constitute an exogenous contributory factor. In this work we aimed at studying the effects of distance (stature) on pulse waveforms. Certain elements of our study showed that pulse wavelength was dominant in prescribing cardio-vascular physiology.

Textbook Aliteracy In Teacher Education: Information Everywhere, But How Much Do They Read?, Rosalind R. Gann, L. Kathryn Sharp, Scott Mcilquham

ETSU Faculty Works

This article explores the problem of textbook aliteracy, i.e. the failure to read assigned texts despite the ability to do so. Constructivism is its theoretical frame. Teacher education students at a medium-sized university in the Southern Appalachian Mountains were surveyed on their textbook reading practices. Ninety percent of the 116 students completing the survey reported studying instructors’ power points in preference to completing assigned readings, at least some of the time. All were readers, though a majority (68%) reported at least some difficulty reading assigned texts. Often, they appeared to be avoiding the challenges posed by demanding text. The authors …

Obstacles And Solutions To Studying Functional Adhesives Using Vibrational Sum-Frequency Generation Spectroscopy, Angela Renee Andersen

Theses and Dissertations

Important aspects of adhesion occur at interfaces, including structures that may be different from those in the bulk materials. However, probing the orientation of molecules in functional adhesives poses a significant challenge because adhesive molecules are always located at a buried interface. The limited penetration depth of surface-specific analysis prohibits the study of buried interfaces using those techniques. The large quantity of bulk molecules relative to the adhesive molecules interacting at the interface results in the bulk signal swamping out adhesive signal in bulk analysis techniques. An interface-specific technique is required to study functional adhesives. One such technique that has …

Second-Order Perturbation Analysis Of The St. Venant Equations In Relation To Bed-Load Transport And Equilibrium Scour Hole Development, Frans Joseph Lambrechtsen

Theses and Dissertations

This analysis is an expansion of research done by Rollin Hotchkiss during his Ph.D work. The research uses fluid flow, sediment transport, and perturbation theory to predict where scour will occur in a variable-width channel. The resulting equations also determine equilibrium scour depth based upon the stream bed elevation derived from a dimensionless bed slope equation. Hotchkiss perturbed the width of the channel using a second order Taylor Series perturbation but neglected second order terms. The present work follows the same procedures as Hotchkiss but maintains the second order terms. The primary purpose is to examine how the additional terms …

Endocannabinoid-Dependent Long-Term Depression Of Ventral Tegmental Area Gaba Neurons, Jared Mark Weed

Theses and Dissertations

GABA neurons in the ventral tegmental area of the midbrain are important components in the brain's reward circuit. Long term changes in this circuit occur through the process of synaptic plasticity. It has been shown that high frequency stimulation, as well as treatment with endocannabinoids, can cause GABA neurons in the ventral tegmental area to undergo long term depression, a form of synaptic plasticity that decreases excitability of cells. The present study elaborates on the mechanism whereby high frequency stimulation can result in long term depression of ventral tegmental area GABA neurons. Using the whole cell patch clamp technique in …

Defining Critical Thinking For The 21st Century World Language Classroom, Bethany Rae Daniel

Theses and Dissertations

Critical thinking has long been recognized as a valuable skill, both in education in general and within the world language teaching field specifically. In recent years, critical thinking has been identified as one of the 21st century skills that students need to succeed in modern society (Partnership, 2009). However, there is no clear, unifying definition of the term itself (Paul, 2004), and the definition of critical thinking is debated in many different fields without support from empirical data (Kuhn, 1999). Similarly, critical thinking has been often discussed in the literature as having great potential to facilitate language learning, and particularly …

Burnout, No, Flame Temperature, And Radiant Intensity From Oxygen-Enriched Combustion Of A Hardwood Biomass, Joshua David Thornock

Theses and Dissertations

Increasing concern for energy sustainability has created motivation for the combustion of renewable, CO2 neutral fuels. Biomass co-firing with coal provides a means of utilizing the scaled efficiencies of coal with the lower supply availability of biomass. One of the challenges of co-firing is the burnout of biomass particles which are typically larger than coal but must be oxidized in the same residence time. Larger biomass particles also can increase the length of the radiative region and alter heat flux profiles. As a result, oxygen injection is being investigated as a means of improving biomass combustion performance.An Air Liquide designed …

Water Fat Separation With Multiple-Acquisition Balanced Steady-State Free Precession Mri, Michael A. Mendoza

Theses and Dissertations

Magnetic resonance imaging (MRI) is an important medical imaging technique for visualizing soft tissue structures in the body. It has the advantages of being noninvasive and, unlike x-ray, does not rely on ionizing radiation for imaging. In traditional hydrogen-based MRI, the strongest measured signals are generated from the hydrogen nuclei contained in water and fat molecules.Reliable and uniform water fat separation can be used to improve medical diagnosis. In many applications the water component is the primary signal of interest, while the fat component represents a signal which can obscure the underlying pathology or other features of interest. In other …

Characterization And Processing Evaluation Of Starch/High-Density Polyethylene Materials In Extrusion Blow Molding, Bradley Dale Bacigalupi

Theses and Dissertations

The growing negative impacts of non-biodegradable plastics derived from non-renewable materials have created increasing interest throughout the world for new materials that are both biodegradable and renewable, that can be combined with or replace traditional plastics. Plant-based thermoplastic starch (TPS), a promising alternative material to traditional petroleum based resin, is both biodegradable and renewable and has great potential for use in plastic manufacturing processes. Two major obstacles that prevent more widespread use of TPS include; TPS base material, which is typically manufactured in a flake or powder, is incompatible with standard plastics production equipment that require pelletized resin, the second …

Involvement Of Principals In Hiring, Professional Development, And Evaluation Of Paraeducators, Jordan T. Hix

Theses and Dissertations

Previous research has found paraeducators do not receive adequate training (Giangreco,Broer, & Edelman, 2002), and are often infrequently evaluated –yearly or less often (Mueller, 2002; Morgan, Ashbaker, & Young, 2001). Little is known about principals' practices relative to paraeducator training, and evaluation. To investigate these topics, a survey was distributed to principals that worked in a large suburban/rural school district in the western United States. Fifty-eight participants completed surveys at a district principals meeting. The results of the study indicated a large majority of principals (78.95% for Title 1 paraeducators, 86.21% for special education paraeducators, and 75.86 for others) hired …

Interface Design And Synthesis For Structural Hybrid Microarchitectural Simulators, Zhuo Ruan

Theses and Dissertations

Computer architects have discovered the potential of using FPGAs to accelerate software microarchitectural simulators. One type of FPGA-accelerated microarchitectural simulator, namedthe hybrid structural microarchitectural simulator, is very promising. This is because a hybrid structural microarchitectural simulator combines structural software and hardware, and this particular organization provides both modeling flexibility and fast simulation speed. The performance of a hybrid simulator is significantly affected by how the interface between software and hardware is constructed. The work of this thesis creates an infrastructure, named Simulator Partitioning Research Infrastructure (SPRI), to implement the synthesis of hybrid structural microarchitectural simulators which includes simulator partitioning, simulator-to-hardware …

“Mad-Speak” And Manic Prose: Nick Cave’S Presentation Of Insanity In And The Ass Saw The Angel, Laura Hardt (Class Of 2014)

English Undergraduate Publications

Nick Cave’s novel And the Ass Saw the Angel attempts to exist firmly within the Southern Gothic tradition, pulling direct inspiration from authors such as William Faulkner, Cormac McCarthy, and Flannery O’Connor. However, Cave’s novel seems to lack the careful construction and purposefulness of these writers, with its graphic violence, constantly shifting tone, style, narrative voice, and employing an utterly bizarre and arcane vocabulary. This essay aims to illustrate that although this may make the work seem poorly composed and somewhat slipshod, the manic prose of Cave’s novel is actually rather purposeful, presenting the protagonist’s descent into madness in an …

Understanding Synesthesia And Impact For Learning, Kateri Lynn Wheeler

Dissertations, Masters Theses, Capstones, and Culminating Projects

Synesthesia is a neurological disorder that has to do with the ‘union of the senses.’ The literature reveals that students with synesthesia are affected with various degrees of severity. Students may hear a bell ring. Their brain is wired to take that sound and interpret it differently, through color, texture, taste, sound or temperature among other things. While some people hear a bell, others may also experience the activation of another sense. The difficulties these students exhibit involves longer processing or thinking time to sort out the extra stimulus. Limiting sound environments and other visual cues like color coding to …
