Effect Of Low Velocity Impact On The Vibrational Behavior Of A Composite Wing, Richard M. De Luna

Master's Theses

Impact strength is one of the most important structural properties for a designer to consider, but it is often the most difficult to quantify or measure. A major concern for composite structures in the field is the effect of foreign objects striking composites because the damage is often undetectable by visual inspection. The objective for this study was to determine the effectiveness of using dynamic testing to identify the existence of damage in a small scale composite wing design. Four different impact locations were tested with three specimens per location for a total of 12 wings manufactured. The different impact …

Dye tracking was to be employed to characterize fluid velocity profiles through the in vitro vascular constructs, including a half-vessel model and a full vessel model of an iliac artery aneurysm. A PDMS half-vessel construct was manufactured, and the movement of dye through the construct was tracked by a cellphone camera. Thresholds were applied to each video in …

Peering In: Improving Existing Buildings With Colorful Increments, Daire Heneghan

Master's Theses

Existing office buildings’ embodied energy, history and culture offer something a newly constructed building cannot. On the other hand, new office buildings’ adoption of new technologies and building philosophies offer a range of sustainable efficiencies previously unavailable. Combining these efficiencies with elements that embrace human diversity and well- being offer the opportunity to not only mend our existing buildings’ deteriorating physical bodies but aid in creating workplaces that promote good physical and mental health.

This project provides recommendation on how an existing high-rise commercial building can incorporate a number of incremental improvements that continually evolve to meet rapidly changing market …

Toward High Performance Nanocarbon Fibers, Michaela R. Pfau

Master's Theses

High performance carbon fibers (CFs) have been a commercially available since their commercial boom in the 1970s, and are generally produced via carbonization of poly (acrylonitrile) (PAN). More recently, carbon nanomaterials like graphene and carbon nanotubes (CNTs) have been discovered and have shown excellent mechanical, thermal, and electrical properties due to their sp² carbon repeating structure. Graphene and CNTs can both be organized into macroscopic fibers using a number of different techniques, resulting in fibers with promising mechanical performance that can be readily multifunctionalized. In some cases, the two materials have been combined, and the resulting hybrid fibers have …

Towards Improved Estimates Of Upper Ocean Energetics, Alexander Grant Wineteer

Master's Theses

The energy exchanged between the atmosphere and the ocean is an important parameter in understanding the Earth’s climate. One way of quantifying this energy exchange is through the use of “wind work,” or the work done on the ocean by the wind. Since wind work is calculated according to the interaction between ocean surface currents and surface wind stress, a number of surface current decompositions can be used to decompose wind work calculations. In this research, geostrophic, ageostrophic, Ekman, and total current decompositions are all used to calculate wind work. Geostrophic currents are formed by the balance of surface pressure …

Deciphering The Outer Envelope Of Thermotoga Maritima, Chaman Ranjit

Master's Theses

Thermotoga maritima is the representative member of the order Thermotogales, which is comprised of extremely thermophilic anaerobic bacteria. All members of this order are characterized by the presence of a unique outer envelope, the toga. The outer envelope appears as polar cellular distensions that sometimes are as large as the cytoplasm. The outer envelope increases in size while the cytoplasm remains the same leading to an outer envelope distension. The outer envelope distension development and increase in its size most likely occurs for storage of nutrients. Initial observations suggest that cells create larger distensions at the poles as they enter …

Cell Phone Vs. Microphone: Judging Emotion In The Voice, Joshua Green

Master's Theses

Abstract

A remarkable amount of information is conveyed by the human voice. For example, the emotional state of a speaker is conveyed by vocal cues such as pitch and intensity, though as is true for other speech qualities, affect does not map onto auditory signals in a one-to-one fashion. Despite the widespread use of cell phone technology, there is still little information regarding how emotional states are conveyed during cell phone transmissions. In this study, listeners judged speech samples for their affective qualities. Samples were simultaneously recorded on a microphone and a cell phone, and endpoints of two emotional “continua,” …

Metrics Dashboard Services: A Framework For Analyzing Free/Open Source Team Repositories, Fnu Shilpika

Master's Theses

Software engineering as practiced today (especially in the industry) is no longer about the stereotypical monolithic life cycle processes (e.g. waterfall, spiral, etc.) found in most software engineering textbooks. These heavyweight methods historically have impeded progress for small/medium sized development teams owing to their inherent complexity and rather limited data collection strategies that predominated the 1980s until relatively recently in the mid-2000s. The discipline and practice of software engineering includes software quality, which has an established theoretical foundation for doing software metrics. Software metrics are a critical tool which provide continuous insight to products and processes and help build reliable …

Activity Recognition For Incomplete Spinal Cord Injury Subjects Using Hidden Markov Models, Pichleap Sok

Master's Theses

Successful activity recognition in patients with motor disabilities can improve patient care by providing researchers and clinicians with valuable information on patient movements and quality of life in real-world settings. Understanding the everyday activities of patients is important for rehabilitation. For researchers, having convenient, objective, and continuous data can drastically improve outcome measures to better compare therapies, and ultimately make recommendations. For clinicians, individual assessment of compliance and outcomes outside the clinic can be more objective, permitting much more tailored recommendations to patients. Most importantly, for individual patients, activity recognition can make this improved health care possible by simply having …

Cortical And Psychological Mechanisms Of Visceral Pain, Kelly L. Polnaszek

Master's Theses

Objective: Dysmenorrhea is an incapacitating type of visceral pain that affects numerous menstruating women and is defined by painful menstrual cramps and often occurs in the absence of pelvic pathology. Women with dysmenorrhea have reported higher sensitivity to experimental pain, and vulnerability to pain sensitivity may be a primary risk factor for developing chronic pelvic pain for women with dysmenorrhea. Cross-organ sensitization (COS), or the theory that uterine inflammation during menstruation can contribute to chronic pelvic pain by generating neurogenic inflammation in other organs, may be a primary mechanism associated with pelvic pain in women with dysmenorrhea. Dysmenorrhea sufferers with …

The Relation Between Appearance Evaluation And Disordered Eating Attitudes Throughout College: Trajectories And Moderators, Amy Heard

Master's Theses

The college years are a time of increased risk for body image concerns and disordered eating in both men and women. Studies have shown that body image concerns may emerge in childhood, increase throughout adolescence, and become more stable in middle adulthood, but less is known about the changes that happen during the college years that may cause these concerns to level off. One of the most common ways of assessing body image is by measuring appearance evaluation, or global satisfaction with appearance. While problematic appearance evaluation and disordered eating attitudes are often associated with one another, all individuals who …

Maimonides And Spinoza: Biblical Interpretation, Randi Feder

Master's Theses

This paper focuses on Maimonides’ The Guide of the Perplexed and Spinoza’s Theological‐Political Treatise and their divergent answers to the question as to whether the knowledge acquired through reason alone can be reconciled with Scripture’s content and teachings. Both Maimonides and Spinoza believed that the true understanding of what the Bible says could be achieved by the correct method of biblical interpretation. I show that despite approaching the question of philosophy’s relationship to religion in a similar way, their very different answers are readily understandable in light of each author’s pre‐existing philosophical and religious commitments. The Guide, published in 1190, …

Use Of Youth Program Quality Assessment (Ypqa) As A Method Of Process Evaluation: Maximizing Limited Resources Of Nonprofit Organizations, Young Im

Master's Theses

Past literature shows the progression of different phases of evaluation practice in nonprofit organizations. Pressure of outcome or impact evaluation started the beginning of the 21st century. The attempt to manage the weight of conducting outcome evaluation has raised many complications, inhibiting the nonprofit organization’s ability to learn and understand the proper role of evaluation and what it can provide to assist in improving programs. It, therefore, has led to a gap in which nonprofits miss what happens during implementation, a crucial part of process evaluation. Among nonprofit organizations in the areas of youth development and after-school programs, various types …

Building And Optimizing A Spectroelectrochemical System For The Study Of Shewanella Putrefaciens, Jonathan Muscolino

Master's Theses

Shewanellaceae are among the most widely studied electroactive microorganisms. This study reports on Shewanella putrefaciens under anaerobic conditions during applied potential while monitored by spectroscopy. The attachment of the microbe Shewanella putrefaciens onto an indium tin oxide electrode was found to occur after 2 hr of +0.2 V applied potential. Microbial detachment occurred with a 5 mV/s scan rate cyclic voltammogram from +0.2 V to -0.5 V to +0.2 V. This was confirmed through use of a spectroelectrochemical apparatus utilizing a standard 3 electrode setup with evanescent wave spectroscopy.

Feminist And Gay Male Politics: New Issues For Political Collaboration And Activism, Adam Hii

Master's Theses

This project looks at political collaboration between people who self-identify as gay men

and those who self-identify as feminists. These two groups have been political aligned on numerous issues since the 1970s. The goal of this project is to see on which issues that political collaboration will continue moving forward. This research draws extensively on oral interviews conducted with gay men and feminists, as well as the current work of national advocacy organizations to see where political interest is high, and where networks already exist to foster future advocacy efforts. By focusing on these areas, this project predicts which issues …

A Bioluminescence Sensor Of Nlrp3 Inflammasome Activation, Michael Alexander Winek

Master's Theses

The innate immune system is many organisms first line of defense against pathogenic insult or tissue damage. This defense strategy is intent on restoring homeostasis upon perturbation. Upon activation of the innate immune system in humans, an oligomeric protein complex termed the “Inflammasome” forms in myeloid cells. The canonical output of activation of any subset of inflammasome is Caspase-1-mediated secretion of pro-inflammatory cytokines IL1β and IL18. Chronic or uncontrolled inflammasome activation is at the core of myriad economically burdening diseases. In many of these diseases, endogenous factors chronically engage the innate immune system. To study these diseases in in vivo, …

Adams As Potential Regulators Of Stem Cell Quiescence In The Olfactory Epithelium, Elaine Elizabeth Orendorff

Master's Theses

I demonstrate that a member of the protein family A Disintegrin and Metalloprotease (ADAM), ADAM23, is expressed in the olfactory epithelium (OE) and may inhibit neural progenitor cell (NPC) proliferation. I generated a list of ten gene candidates and selected ADAM23 for further study, based on its conserved protein structure and accumulating evidence for its role in cell cycle progression of proliferative cells. I next determined ADAM23 protein localization using immunohistochemistry and measured both mRNA and protein expression post-lesion with RT-qPCR and Western blot. ADAM23 is expressed in multiple cell types of the OE, including glial Sustentacular (Sus) cells and …

Spest – A Tool For Specification-Based Testing, Corrigan Redford Johnson

Master's Theses

This thesis presents a tool for SPEcification based teSTing (SPEST). SPEST is designed to use well known practices for automated black-box testing to reduce the burden of testing on developers. The tool uses a simple formal specification language to generate highly-readable unit tests that embody best practices for thorough software testing. Because the specification language used to generate the assertions about the code can be compiled, it can also be used to ensure that documentation describing the code is maintained during development and refactoring.

The utility and effectiveness of SPEST were validated through several exper- iments conducted with students in …

Simulating And Understanding A Summertime Dry Lightning Event In Coastal California, Philip Isaac Martin

Master's Theses

Thunderstorms are rare in coastal California during the summer months. Synoptic situations that encourage these summertime thunderstorms typically involve elevated instability that promotes dry lightning thunderstorms, where less than 0.1 in of precipitation reaches the ground. On 21 June 2008, a poorly forecasted dry lightning outbreak was responsible for starting more than 1,500 wildfires across California, and specifically the Monterey region. In this research, we used analysis data from the Global Forecast System (GFS) model to investigate the evolution of the synoptic conditions leading up to the outbreak. We then created two sets of ensembles with the Weather Research and …

Testing Camera Trap Density Estimates From The Spatial Capture Model And Calibrated Capture Rate Indices Against Kangaroo Rat (Dipodomys Spp.) Live Trapping Data, Timothy A. Walker

Master's Theses

Camera trapping studies often focus on estimating population density, which is critical for managing wild populations. Density estimators typically require unique markers such as stripe patterns to identify individuals but most animals do not have such markings. The spatial capture model (SC model; Chandler & Royle, 2013) estimates density without individual identification but lacks sufficient field testing. Here, both the SC model and calibrated capture rate indices were compared against ten sessions of live trapping data on kangaroo rats (Dipodomys spp). These camera and live trapping data were combined in a joint-likelihood model to further compare the two methods. From …

Diagnostic Practices Of Autism Spectrum Disorders In Brazil, Ana Claudia Vespa Mainer Dias

Master's Theses

In Brazil, in spite of over half a million students with special needs in primary education, little research has been conducted about ASD diagnostic practices. This involves learning about the training that professionals are receiving, what diagnostic practices are being implemented on the field, and whether those are being contextualized according to the Brazilian culture. Students with special needs are directly affected by the results of diagnostic practices, since identifying the individuals is one of the first steps. Lack of understanding about that stage may lead to the problematic realities of underidentification or overidentification, exclusion of children who should receive …

Soteriological Specifics In Paul, James, John, And Peter, Dominik Buchner

Master's Theses

Topic

The ideas of New Testament authors seem to stand in contradiction to each other: some appear to focus on justification by faith, whereas others seems to proclaim that works need to be performed in order to be saved. It is therefore very difficult to deduce relevant practical implications from the doctrine of salvation because it is often explained in a rather superficial and dissatisfactory way.

Purpose

The development of the interpretation of the doctrine of salvation is outlined in a chapter about church history. In the following chapter relevant Bible text passages in Paul, James, John, and Peter about …

Predicting Suitable Habitat Decline Of Midwestern United States Amphibians And Quantifying The Consequence Of Declines Using Pond-Breeding Salamanders, Brock Struecker

Master's Theses

With current declines of vertebrate taxa meeting or exceeding those of historic mass extinction events, there is a growing need to investigate the main drivers of declines. Amphibians are perhaps at greatest risk of global climate change and land-use changes than most other vertebrate classes and also have significant roles in ecosystem processes – combined, this creates a cause for concern. I designed a study that would investigate the effects of current and predicted climate change and land-use changes on amphibians using species distribution models and a field study to identify the potential consequences of amphibian species declines by investigating …

Role Of Pkc Delta In Uv Radiation Dna Damage Repair, Gargi Patil

Master's Theses

DNA damage caused by ultraviolet radiation (UV), such as cyclobutane pyrimidine dimers (CPD), is repaired by the nucleotide excision repair (NER) pathway. When NER is defective, DNA damage is not repaired, leading to mutations and skin cancer. After DNA damage, the cell cycle is halted at various checkpoints to allow time for repair of the damage and maintain genomic integrity, however little is known about the coordination between NER DNA damage repair and cell cycle halting at checkpoints after DNA damage. Protein kinase C δ (PKCδ) plays major role in apoptosis and maintains the G2/M checkpoint in response to UV …

Lactobacillus Crispatus Produces A Bacteridical Molecule That Kills Uropathogenic E. Coli, Katherine Diebel

Master's Theses

As many as 1 in 2 women will have at least one urinary tract infection (UTI) in their lifetime. UTIs can cause complications in pregnancy and decrease quality of life, and their treatment and prevention are expensive. Uropathogenic E. coli (UPEC) is the primary cause of UTI. The probiotic and bactericidal capacities of gut and vaginal Lactobacillus isolates have been studied, but the same attention has not been paid to urinary strains. These urinary isolates of L. crispatus appear to have a greater killing capacity against UPEC and this bactericidal activity does not depend on the cells themselves, consistent with …
