MAJOR PROFESSOR: Dr. Scott Gilbert

The consumer price index (CPI) and the producer price index (PPI) are important indicators of price monitoring and analysis. The accurate relationship between PPI and CPI is essential for monitoring and managing inflation. In theory, consumer price index and the producer price index should exist in a sequence and conduction relationship. But the data …


Design And Analysis Of Bio-Inspired Nacelle For Current Energy Turbine, Michael Coe Dec 2017

Design And Analysis Of Bio-Inspired Nacelle For Current Energy Turbine, Michael Coe

Master's Theses

he world’s oceans contain a substantial amount of energy, stored in ocean currents and waves. Ocean current energy can be extracted using similar principles to existing wind energy platforms. A problem with such extraction methods is that the velocity of the fluid in ocean currents is too low for efficient energy generation. A potential solution to this problem is the use of a concentrator or diffuser to increase fluid velocity to the blades, but this carries with it extra costs. A more cost effective solution to this problem is presented by the use of a down flow current turbine in …


Youth Sport Development Pathways And Experiences Of Ncaa Division I Women's College Soccer Players, Emily Hardell Dec 2017

Youth Sport Development Pathways And Experiences Of Ncaa Division I Women's College Soccer Players, Emily Hardell

Master's Theses

As youth sport has become increasingly professionalized, many believe that the route to elite level play is through early specialization. Early specialization is a contentious issue, and many risk factors have been associated with high levels and intensities of training in youth. Youth today participate in highly competitive sport in pursuit of elite levels of play, recognition, and financial gain. Early specialization is thought to be a requirement for advancement, yet little is known about the early experiences of team sport athletes who grew up in the US. This is the story of 15 elite female athletes who “made it” …


Community Structure And Zonation Of Antarctic Benthic Invertebrates: Using A Remotely Operated Vehicle Under Ice To Define Biological Patterns, Dorota Szuta Dec 2017

Community Structure And Zonation Of Antarctic Benthic Invertebrates: Using A Remotely Operated Vehicle Under Ice To Define Biological Patterns, Dorota Szuta

Master's Theses

The Ross Sea, Antarctica is a deep bay of the Southern Ocean that exhibits seasonal sea ice and is adjacent to a permanent ice shelf overlying seawater. In 2008 and 2009, imagery of the seafloor under the McMurdo Ice Shelf and under the seasonal ice in the Ross Sea was collected via remotely operated vehicle (ROV) at depths to 300 m. Distinct differences in Antarctic benthic communities were observed over multiple environmental gradients. Species abundance typically exhibited a unimodal distribution with depth with mid-depth peaks, reflecting a food limitation at the deep end and potentially ice disturbance on the shallow …


The Common Lot Of Nature: The Stoic Concept Of Death In The Writings Of St. Ambrose, Nathan Michael Falls Hall Dec 2017

The Common Lot Of Nature: The Stoic Concept Of Death In The Writings Of St. Ambrose, Nathan Michael Falls Hall

Master's Theses

The Common Lot of Nature is a comparative analysis which questions the completeness of St. Ambrose’s Christian faith. The comparison focuses specifically on notions of death, and how one should deal with its presence in one’s life. This emphasis was chosen because Ambrose was a Christian bishop who was heavily influenced by Stoicism, and these two worldviews held contrasting beliefs on how death fits into the lives of human beings. The paper begins with an outline of other research regarding Stoicism or its potential connections with Christianity. The following two sections discuss how Stoics and 4th century Christians conceptualized death …


Geophysical Characterization Of A Rare Earth Element Enriched Carbonatite Terrane At Mountain Pass, California Eastern Mojave Desert, Kevin Denton Dec 2017

Geophysical Characterization Of A Rare Earth Element Enriched Carbonatite Terrane At Mountain Pass, California Eastern Mojave Desert, Kevin Denton

Master's Theses

Mountain Pass, California, located in the eastern Mojave Desert, hosts one of the world's richest rare earth element (REE) deposits. The REE-rich rocks occur in a 2.5 km- wide, north-northwest trending zone of Mesoproterozoic (1.4–1.42 Ga) stocks and dikes, which intrude a larger Paleoproterozoic (1.7 Ga) schist-gneiss terrane that extends ~10 km southward from Clark Mountain to the Mescal Range. Several REE-enriched bodies make up the Mountain Pass intrusive suite including shonkinite, syenite, and granite comprising an ultrapotassic intrusive suite and the Sulphide Queen carbonatite body.

Two-dimensional modeling of gravity, magnetic, and electrical resistivity data reveals that the Mountain Pass …


A Full Factorial Analysis Of Polymerization Conditions Of Sodium Alginate Beads To Determine The Effect On Diffusivity And Concentration Limit Of Tryptophan And Glucose, Allison Schulkins Dec 2017

A Full Factorial Analysis Of Polymerization Conditions Of Sodium Alginate Beads To Determine The Effect On Diffusivity And Concentration Limit Of Tryptophan And Glucose, Allison Schulkins

Master's Theses

The purpose of this work is to develop an experimental setup with associated mathematical analysis to analyze the changes in diffusivity through calcium alginate gel beads made under different polymerization conditions. The diffusivity of the solutes glucose and tryptophan was calculated by measuring the concentration change over time as solute diffused out of the alginate spheres and into the bulk. The alginate beads were generated using different polymerization conditions following a two-level, three-factor, full-factorial matrix with alginate concentration, cross-linker concentration, and cross-linking time as the factors. The diffusivities showed variations between different conditions, which were analyzed to determine the main …


Multi-Scale Studies To Develop A Holistic Understanding Of Solid Fuel Combustion At Residential Scale, Sameer Patel Dec 2017

Multi-Scale Studies To Develop A Holistic Understanding Of Solid Fuel Combustion At Residential Scale, Sameer Patel

McKelvey School of Engineering Graduate Student Theses & Dissertations

Nearly 3 billion people rely on solid fuels for their cooking and heating needs, classifying them as “energy poor”. This poverty can be attributed to several factors, including a lack of resources (fuel), inefficient infrastructure (production and distribution), limited purchasing power (poverty), and ill-devised policies. Solid fuels, such as biomass, coal, and dung cakes, are burned in inefficient cookstoves. They generate products of incomplete combustion (PIC), such as CO, particulate matter (PM), and CH4, causing household air pollution (HAP) whose adverse impacts on both health and the environment have been well established.

HAP causes diseases such as chronic obstructive pulmonary …


The Inter-Laminar Shearing Effect On Wrinkle Development In Composite Forming Processes, David Sundquist Dec 2017

The Inter-Laminar Shearing Effect On Wrinkle Development In Composite Forming Processes, David Sundquist

McKelvey School of Engineering Graduate Student Theses & Dissertations

Composite materials are becoming prevalent in aerospace industries as the uniqueness of the composite structure allows the composite to be tailored specifically for individual applications. Many fabrication techniques produce defects in composite parts such as wrinkles, fiber waviness, fiber misalignment, and porosity. The driving mechanisms behind these defects occurring during forming processes are not fully understood and, thus, characterization formation of these defects in a uncured state is beneficial to optimize composite processing. This work primarily investigated the influence of how uncured pre-impregnated carbon ply properties affect the wrinkling behavior of a composite laminates. Several factors affecting composite ply forming …


Characterizing Anisotropy In Fibrous Soft Materials By Mr Elastography Of Slow And Fast Shear Waves, John Larson Schmidt Dec 2017

Characterizing Anisotropy In Fibrous Soft Materials By Mr Elastography Of Slow And Fast Shear Waves, John Larson Schmidt

McKelvey School of Engineering Graduate Student Theses & Dissertations

The general objective of this work was to develop experimental methods based on magnetic resonance elastography (MRE) to characterize fibrous soft materials. Mathematical models of tissue biomechanics capable of predicting injury, such as traumatic brain injury (TBI), are of great interest and potential. However, the accuracy of predictions from such models depends on accuracy of the underlying material parameters. This dissertation describes work toward three aims. First, experimental methods were designed to characterize fibrous materials based on a transversely isotropic material model. Second, these methods are applied to characterize the anisotropic properties of white matter brain tissue ex vivo. Third, …


Gendered Impacts Of Community-Based Conservation Initiatives In Kimana/Tikondo Group Ranch Outside Of Amboseli National Park, Megan Clemens Dec 2017

Gendered Impacts Of Community-Based Conservation Initiatives In Kimana/Tikondo Group Ranch Outside Of Amboseli National Park, Megan Clemens

Master's Theses

Community-based conservation has become a common solution to addressing local communities needs and concerns when it comes to conservation initiatives associated with, or outside the boundaries of national parks. Community-based initiatives associated with Amboseli National Park in southern Kenya mark one of the first attempts to include local communities in conservation initiatives and management as well as establish systems of benefit sharing between conservation and local communities. However, a critique of community-based conservation initiatives points out they often assume community homogeneity. Assumption of community homogeneity leads to inequities in benefits sharing, exclusion of subgroups (women, ethnic minorities) or even exacerbate …


Exploring Employment Equity: Diversity & Inclusion In Canada’S Legislation & Policy, Vanessa Toussaint Miller Dec 2017

Exploring Employment Equity: Diversity & Inclusion In Canada’S Legislation & Policy, Vanessa Toussaint Miller

Master's Theses

Multiculturalism is considered very much a part of Canada’s national heritage and identity, becoming the first nation to adopt multiculturalism as an official policy in 1971. Over the last 40 years, the Canadian population has undergone significant changes bringing in immigrants with different cultures, ideologies, religions and ways of life. Despite the various changes in society, the multiculturalism policies have remained the same. This thesis examines Canada’s Employment Equity-a policy intended to eliminate systemic discrimination in the workplace-and its effectivity at creating a diverse and inclusive workforce. The main research question is, in the past five years, has Employment Equity …


How Patriotic Are Albanians? The Comparative Study Of Patriotic Attitudes In Albania And The Albanian Diaspora, Anxhela Spahiu Dec 2017

How Patriotic Are Albanians? The Comparative Study Of Patriotic Attitudes In Albania And The Albanian Diaspora, Anxhela Spahiu

Master's Theses

In today’s post-modern digital world, patriotism may not be as prevalent as in the past. In this thesis, my principal aim is to investigate to what extent Albanians, a nationality to which I belong, identify with a patriotic attitude toward Albania. I chose to focus not only on Albanians who live in the diaspora, like myself, but also on Albanians who live in Albania. I believe that to understand national pride to its fullest, you must study the attitudes of those who live in the country of origin as well as of those who live in the diaspora. Many people …


First Narrow-Band Search For Continuous Gravitational Waves From Known Pulsars In Advanced Detector Data, B. P. Abbott, R. Abbott, T. D. Abbott, F. Acernese, K. Ackley, Teviet Creighton, Mario C. Diaz, Soma Mukherjee, Volker Quetschke, Malik Rakhmanov Dec 2017

First Narrow-Band Search For Continuous Gravitational Waves From Known Pulsars In Advanced Detector Data, B. P. Abbott, R. Abbott, T. D. Abbott, F. Acernese, K. Ackley, Teviet Creighton, Mario C. Diaz, Soma Mukherjee, Volker Quetschke, Malik Rakhmanov

Physics & Astronomy Faculty Publications

Spinning neutron stars asymmetric with respect to their rotation axis are potential sources of continuous gravitational waves for ground-based interferometric detectors. In the case of known pulsars a fully coherent search, based on matched filtering, which uses the position and rotational parameters obtained from electromagnetic observations, can be carried out. Matched filtering maximizes the signal-to-noise (SNR) ratio, but a large sensitivity loss is expected in case of even a very small mismatch between the assumed and the true signal parameters. For this reason, narrow-band analysis methods have been developed, allowing a fully coherent search for gravitational waves from known pulsars …


First Low-Frequency Einstein@Home All-Sky Search For Continuous Gravitational Waves In Advanced Ligo Data, B. P. Abbott, R. Abbott, T. D. Abbott, F. Acernese, K. Ackley, C. Adams, Teviet Creighton, Soma Mukherjee, Volker Quetschke, Malik Rakhmanov Dec 2017

First Low-Frequency Einstein@Home All-Sky Search For Continuous Gravitational Waves In Advanced Ligo Data, B. P. Abbott, R. Abbott, T. D. Abbott, F. Acernese, K. Ackley, C. Adams, Teviet Creighton, Soma Mukherjee, Volker Quetschke, Malik Rakhmanov

Physics & Astronomy Faculty Publications

We report results of a deep all-sky search for periodic gravitational waves from isolated neutron stars in data from the first Advanced LIGO observing run. This search investigates the low frequency range of Advanced LIGO data, between 20 and 100 Hz, much of which was not explored in initial LIGO. The search was made possible by the computing power provided by the volunteers of the Einstein@Home project. We find no significant signal candidate and set the most stringent upper limits to date on the amplitude of gravitational wave signals from the target population, corresponding to a sensitivity depth of 48.7 …


A Comprehensive Evaluation Of Feature Selection For Gait Recognition Using Smartwatches, N Al-Naffakh, Nathan Clarke, P Haskell-Dowland, Fudong Li Dec 2017

A Comprehensive Evaluation Of Feature Selection For Gait Recognition Using Smartwatches, N Al-Naffakh, Nathan Clarke, P Haskell-Dowland, Fudong Li

School of Engineering, Computing and Mathematics

Activity recognition that recognises who a user is by what they are doing at a specific point of time is attracting an enormous amount of attention. Whilst previous research in activity recognition has focused on wearable dedicated sensors (body worn sensors) or using a smartphone’s sensors (e.g. accelerometer and gyroscope), little attention is given to the use of wearable devices – which tend to be sensor-rich highly personal technologies. This paper presents a thorough analysis of the current state of the art in transparent and continuous authentication using acceleration and gyroscope sensors and an advanced feature selection approach to select …

Locality-Aware Concurrency Platforms, Jordyn Chrystopher Raymond Maglalang Dec 2017

Locality-Aware Concurrency Platforms, Jordyn Chrystopher Raymond Maglalang

McKelvey School of Engineering Graduate Student Theses & Dissertations

Modern computing systems from all domains are becoming increasingly more parallel. Manufacturers are taking advantage of the increasing number of available transistors by packaging more and more computing resources together on a single chip or within a single system. These platforms generally contain many levels of private and shared caches in addition to physically distributed main memory. Therefore, some memory is more expensive to access than other and high-performance software must consider memory locality as one of the first level considerations.

Memory locality is often difficult for application developers to consider directly, however, since many of these NUMA affects are …


Accurate Determination And Application Of Local Strain For Studying Tissues With Gradients In Mechanical Properties, John Boyle Dec 2017

Accurate Determination And Application Of Local Strain For Studying Tissues With Gradients In Mechanical Properties, John Boyle

McKelvey School of Engineering Graduate Student Theses & Dissertations

Determination of the mechanical behavior of materials requires an understanding of deformation during loading. While this is traditionally accomplished in engineering by examining a force displacement curve for a whole sample, these techniques implicitly ignore local geometric complexities and local material inhomogeneities commonly found in biologic tissues. Techniques such as normalized cross correlation have been classically applied to address this issue and resolve deformation at the local level; however, these techniques have proven unreliable when deformations become large, if the sample undergoes a rotation, and/or if strain fields become incompatible (e.g. at or near failure).

Presented here is a toolbox …


Multiscale Imaging Of The Mouse Cortex Using Two-Photon Microscopy And Wide-Field Illumination, Jonathan Richard Bumstead Dec 2017

Multiscale Imaging Of The Mouse Cortex Using Two-Photon Microscopy And Wide-Field Illumination, Jonathan Richard Bumstead

McKelvey School of Engineering Graduate Student Theses & Dissertations

The mouse brain can be studied over vast spatial scales ranging from microscopic imaging of single neurons to macroscopic measurements of hemodynamics acquired over the majority of the mouse cortex. However, most neuroimaging modalities are limited by a fundamental trade-off between the spatial resolution and the field-of-view (FOV) over which the brain can be imaged, making it difficult to fully understand the functional and structural architecture of the healthy mouse brain and its disruption in disease. My dissertation has focused on developing multiscale optical systems capable of imaging the mouse brain at both microscopic and mesoscopic spatial scales, specifically addressing …


A Generalized Biophysical Model Of Transcription Factor Binding Specificity And Its Application On High-Throughput Selex Data, Shuxiang Ruan Dec 2017

A Generalized Biophysical Model Of Transcription Factor Binding Specificity And Its Application On High-Throughput Selex Data, Shuxiang Ruan

Arts & Sciences Graduate Student Theses and Dissertations

The interaction between transcription factors (TFs) and DNA plays an important role in gene expression regulation. In the past, experiments on protein–DNA interactions could only identify a handful of sequences that a TF binds with high affinities. In recent years, several high-throughput experimental techniques, such as high-throughput SELEX (HT-SELEX), protein-binding microarrays (PBMs) and ChIP-seq, have been developed to estimate the relative binding affinities of large numbers of DNA sequences both in vitro and in vivo. The large volume of data generated by these techniques proved to be a challenge and prompted the development of novel motif discovery algorithms. These algorithms …


Fast Monte Carlo Simulations For Quality Assurance In Radiation Therapy, Yuhe Wang Dec 2017

Fast Monte Carlo Simulations For Quality Assurance In Radiation Therapy, Yuhe Wang

Arts & Sciences Graduate Student Theses and Dissertations

Monte Carlo (MC) simulation is generally considered to be the most accurate method for dose calculation in radiation therapy. However, it suffers from the low simulation efficiency (hours to days) and complex configuration, which impede its applications in clinical studies. The recent rise of MRI-guided radiation platform (e.g. ViewRay’s MRIdian system) brings urgent need of fast MC algorithms because the introduced strong magnetic field may cause big errors to other algorithms. My dissertation focuses on resolving the conflict between accuracy and efficiency of MC simulations through 4 different approaches: (1) GPU parallel computation, (2) Transport mechanism simplification, (3) Variance reduction, …


The Chemistry And Biology Of Iron-Scavenging Natural Products From Pathogenic Acinetobacter Baumannii, Justin Shapiro Dec 2017

The Chemistry And Biology Of Iron-Scavenging Natural Products From Pathogenic Acinetobacter Baumannii, Justin Shapiro

Arts & Sciences Graduate Student Theses and Dissertations

Multidrug resistant (MDR) Gram-negative bacteria represent a global health crisis. Traditional antibiotics create selective pressure and breed resistance, making our current drugs less and less effective. Targeting of bacterial virulence factors has gained interest as an alternative strategy to potentially circumvent this problem. Virulent Acinetobacter baumannii synthesize and secrete pre-acinetobactin, a small molecule metal chelator that scavenges life-sustaining iron and is critical for establishing infection. The work described herein sheds light on the unusual properties of a non-enzymatic isomerization from pre-acinetobactin to acinetobactin and proposes a siderophore-swapping mechanism by which A. baumannii expands its pH window for virulence. Knowledge from …


Mechanism Of Gene Regulation By Coding Polya Tracks, Laura Lea Arthur Dec 2017

Mechanism Of Gene Regulation By Coding Polya Tracks, Laura Lea Arthur

Arts & Sciences Graduate Student Theses and Dissertations

Regulation of gene expression is essential for cellular development and survival. The great variety and complexity of regulatory mechanisms underscores this fact. Messenger RNA stability and translational efficiency are often key determinants of gene expression. mRNA surveillance pathways, discovered for their role in degradation of aberrant mRNA, are now known to be instrumental in the regulation of physiologically correct mRNA stability. Thus, the study of cis elements in a transcript that can induce mRNA surveillance pathways has become an area of particular interest.Here I report on the mechanism of gene regulation by coding polyA tracks, defined as a sequence of …


Structured Illumination Diffuse Optical Tomography For Mouse Brain Imaging, Matthew Reisman Dec 2017

Structured Illumination Diffuse Optical Tomography For Mouse Brain Imaging, Matthew Reisman

Arts & Sciences Graduate Student Theses and Dissertations

As advances in functional magnetic resonance imaging (fMRI) have transformed the study of human brain function, they have also widened the divide between standard research techniques used in humans and those used in mice, where high quality images are difficult to obtain using fMRI given the small volume of the mouse brain. Optical imaging techniques have been developed to study mouse brain networks, which are highly valuable given the ability to study brain disease treatments or development in a controlled environment. A planar imaging technique known as optical intrinsic signal (OIS) imaging has been a powerful tool for capturing functional …


The Nets Of Style: Shaping Modernist Literary Narrative, Kelly Lynn Oman Dec 2017

The Nets Of Style: Shaping Modernist Literary Narrative, Kelly Lynn Oman

Arts & Sciences Graduate Student Theses and Dissertations

Literary modernism is often defined by a stylistic distinctiveness generated by experiments in subject and form. Given that these experiments necessarily break with convention, how are we to make sense of this style without those conventions to guide us? In “The Nets of Style: Shaping Modernist Literary Narrative,” I reveal how critical definitions of modernist style often rely on the individualist poses struck and critical pronouncements made by modernists themselves. My research is situated in a body of work in modernist studies that argue, as Paul Sheehan does in Modernism and the Aesthetics of Violence, that “modernism seeks to transform …


Roles Of Peroxisomes And Peroxisome-Derived Products In Controlling Plant Growth And Stress Responses, Elizabeth May Frick Dec 2017

Roles Of Peroxisomes And Peroxisome-Derived Products In Controlling Plant Growth And Stress Responses, Elizabeth May Frick

Arts & Sciences Graduate Student Theses and Dissertations

The peroxisome is a vital organelle conserved through the entire eukaryotic lineage. In all examined species, peroxisomes are responsible for such essential processes as fatty acid beta-oxidation and metabolism of reactive oxygen species (ROS). In plants, peroxisomes have taken on additional specialized roles, such as production of some plant hormones and vitamins. In this work, I have uncovered novel factors regulating peroxisome number in model species Arabidopsis thaliana, and novel mechanisms governing how peroxisomes respond to salt stress. I discovered a role for Arabidopsis MAP KINASE17 (MPK17) as a negative regulator of peroxisome division that acts in the salt-stress response …


Analysis Of Argonaute-Small Rna-Transcription Factor Circuits Controlling Leaf Development, John Steen Hoyer Dec 2017

Analysis Of Argonaute-Small Rna-Transcription Factor Circuits Controlling Leaf Development, John Steen Hoyer

Arts & Sciences Graduate Student Theses and Dissertations

Experimental studies of plant development have yielded many insights into gene regulation, revealing interactions between core transcriptional and post-transcriptional regulatory pathways present in all land plants. This work describes a direct connection between the three main small RNA-transcription factor circuits controlling leaf shape dynamics in the reference plant Arabidopsis thaliana. We used a high-throughput yeast 1-hybrid platform to identify factors directly binding the promoter of the highly specialized ARGONAUTE7 silencing factor. Two groups of developmentally significant microRNA-targeted transcription factors were the clearest hits from these screens, but transgenic complementation analysis indicated that their binding sites make only a small contribution …


Bio-Inspired Multi-Spectral And Polarization Imaging Sensors For Image-Guided Surgery, Nimrod Missael Garcia Dec 2017

Bio-Inspired Multi-Spectral And Polarization Imaging Sensors For Image-Guided Surgery, Nimrod Missael Garcia

McKelvey School of Engineering Graduate Student Theses & Dissertations

Image-guided surgery (IGS) can enhance cancer treatment by decreasing, and ideally eliminating, positive tumor margins and iatrogenic damage to healthy tissue. Current state-of-the-art near-infrared fluorescence imaging systems are bulky, costly, lack sensitivity under surgical illumination, and lack co-registration accuracy between multimodal images. As a result, an overwhelming majority of physicians still rely on their unaided eyes and palpation as the primary sensing modalities to distinguish cancerous from healthy tissue. In my thesis, I have addressed these challenges in IGC by mimicking the visual systems of several animals to construct low power, compact and highly sensitive multi-spectral and color-polarization sensors. I …


Image Reconstruction Of The Speed Of Sound And Initial Pressure Distributions In Ultrasound Computed Tomography And Photoacoustic Computed Tomography, Thomas Paul Matthews Dec 2017

Image Reconstruction Of The Speed Of Sound And Initial Pressure Distributions In Ultrasound Computed Tomography And Photoacoustic Computed Tomography, Thomas Paul Matthews

McKelvey School of Engineering Graduate Student Theses & Dissertations

Ultrasound computed tomography (USCT) and photoacoustic computed tomography (PACT) are two emerging imaging modalities that have a wide range of potential applications from pre-clinical small animal imaging to cancer screening in human subjects. USCT is typically employed to measure acoustic contrasts, including the speed of sound (SOS) distribution, while PACT typically measures optical contrasts or some related quantity such as the initial pressure distribution. Their complementary contrasts and similar implementations make USCT and PACT a natural fit for a hybrid imaging system. Still, much work remains to realize this promise. First, USCT image reconstruction methods based on the acoustic wave …
