We have investigated particle acceleration and shock structure associated with an unmagnetized rel-ativistic jet propagating into an unmagnetized plasma for electron-positron and electron-ion plasmas. Strong magnetic fields generated in the trailing jet shock lead to transverse deflection and acceleration of the electrons. We have self-consistently calculated the radiation from the electrons accelerated in the turbulent magnetic fields for different jet Lorentz factors. We find that the synthetic spectra depend on the bulk Lorentz factor of the jet, the jet temperature, and the strength of the magnetic fields generated in the shock. We have investigated the generation of magnetic fields associated …

A Deep Search For Host Galaxies Of Grbs With No Detected Optical Afterglow, A. Rossi, S. Klose, P. Ferrero, J. Greiner, L. A. Arnold, E. Gonslaves, Dieter H. Hartmann, A. C. Updike, D. A. Kann, T. Krühler

Publications

Context. Gamma-ray bursts (GRBs) can provide information about star formation at high redshifts. Even in the absence of a bright optical/near-infrared/radio afterglow, the high detection rate of X-ray afterglows by Swift/XRT and its localization precision of 2–3 arcsec facilitates the identification and the study of GRB host galaxies. Aims. We focus on the search for the host galaxies of 17 bursts with arcsec-sized XRT error circles but no detected long-wavelength afterglow, in spite of their deep and rapid follow-up observations. Three of these events can also be classified as truly dark bursts, i.e., the observed upper limit on the optical …

Highly Efficient And Exact Method For Parallelization Of Grid-Based Algorithms And Its Implementation In Delphi, Chuan Li, Lin Li, Jie Zhang, Emil Alexov Sep 2012

Highly Efficient And Exact Method For Parallelization Of Grid-Based Algorithms And Its Implementation In Delphi, Chuan Li, Lin Li, Jie Zhang, Emil Alexov

Publications

The Gauss–Seidel (GS) method is a standard iterative numerical method widely used to solve a system of equations and, in general, is more efficient comparing to other iterative methods, such as the Jacobi method. However, standard implementation of the GS method restricts its utilization in parallel computing due to its requirement of using updated neighboring values (i.e., in current iteration) as soon as they are available. Here, we report an efficient and exact (not requiring assumptions) method to parallelize iterations and to reduce the computational time as a linear/nearly linear function of the number of processes or computing units. In …

A Genome-Wide Over-Expression Screen Identifies Genes Involved In Phagocytosis In The Human Protozoan Parasite, Entamoeba Histolytica, Ada V. King, Brenda H. Welter, Amrita B. Koushik, Lindsay N. Gordon, Lesly A. Temesvari

Publications

Functional genomics and forward genetics seek to assign function to all known genes in a genome. Entamoeba histolytica is a protozoan parasite for which forward genetics approaches have not been extensively applied. It is the causative agent of amoebic dysentery and liver abscess, and infection is prevalent in developing countries that cannot prevent its fecal-oral spread. It is responsible for considerable global morbidity and mortality. Given that the E. histolytica genome has been sequenced, it should be possible to apply genomic approaches to discover gene function. We used a genome-wide over-expression screen to uncover genes regulating an important virulence function …

On The Cyclically Fully Commutative Elements Of Coxeter Groups, T. Boothby, J. Burket, M. Eichwald, D. C. Ernst, R. M. Green, Matthew Macauley Aug 2012

On The Cyclically Fully Commutative Elements Of Coxeter Groups, T. Boothby, J. Burket, M. Eichwald, D. C. Ernst, R. M. Green, Matthew Macauley

Publications

Let W be an arbitrary Coxeter group. If two elements have expressions that are cyclic shifts of each other (as words), then they are conjugate (as group elements) in W. We say that w is cyclically fully commutative (CFC) if every cyclic shift of any reduced expression for w is fully commutative (i.e., avoids long braid relations). These generalize Coxeter elements in that their reduced expressions can be described combinatorially by acyclic directed graphs, and cyclically shifting corresponds to source-to-sink conversions. In this paper, we explore the combinatorics of the CFC elements and enumerate them in all Coxeter groups. …

A Multi-Tiered Approach To Evaluating A Nonformal Youth Development Program, Jill Walahoski, Suzanne Menestrel Aug 2012

A Multi-Tiered Approach To Evaluating A Nonformal Youth Development Program, Jill Walahoski, Suzanne Menestrel

Journal of Youth Development

It is essential for nonformal educational organizations to evaluate their programs and validate impact. However, despite recent pressures for accountability, nonformal settings often do not have shared assessment measures or expectations. Further, many nonformal programs are complex and encompass a broad range of educational settings and methods. Evaluation strategies must respond to a more learner-centered approach to education and be responsive to local needs, but they must also be designed with an appropriate level of methodological rigor. This paper describes the efforts of the National 4-H Science Initiative to develop and administer a multi-tiered evaluation that effectively documents impact through …

Mass Latex Balloon Releases And The Potential Effects On Wildlife, Stephan Irwin Aug 2012

Mass Latex Balloon Releases And The Potential Effects On Wildlife, Stephan Irwin

All Dissertations

The first component of the study examined the fate of balloons after release to determine aspects of where, in what state, and how long they persist in the environment to assess potential risk of exposure to wildlife. Tagged balloons from sporting events gave estimates of mean distances traveled from releases. Effects on the structural integrity of the latex balloon as it reaches the upper atmosphere were also tested to determine the physical state when fragments landed. Degradation studies were conducted to determine the length of time latex can persist in the environment after exposure to various environmental conditions (sun, shade, …

Essays In Labor Economics, Adam Blott Aug 2012

Essays In Labor Economics, Adam Blott

All Dissertations

The three chapters of this dissertation are closely related to one another and pertain to work flexibility. The first chapter uses an occupational choice model to estimate how workers value schedule flexibility in terms of other on the job characteristics. The second chapter also estimates how workers value flexibility using a hedonic wage approach. This method provides an estimate of how workers value schedule flexibility in terms of real wages. In the third chapter I estimate the impact of family structure on the probability that men choose a flexible job.
Flexible work schedules are becoming an increasingly important characteristic for …

Physicic-Based Algorithms And Divergence Free Finite Elements For Coupled Flow Problems, Nicholas Wilson Aug 2012

Physicic-Based Algorithms And Divergence Free Finite Elements For Coupled Flow Problems, Nicholas Wilson

All Dissertations

This thesis studies novel physics-based methods for
simulating incompressible fluid flow described by the Navier-Stokes equations (NSE) and
magnetohydrodynamics equations (MHD).
It is widely accepted in computational fluid dynamics (CFD) that numerical schemes which are more
physically accurate lead to more precise flow simulations especially over long time intervals.
A prevalent theme throughout will be the inclusion of as much
physical fidelity in numerical solutions as efficiently possible. In algorithm design, model
selection/development, and element choice, subtle changes can provide better physical accuracy,
which in turn provides better overall accuracy (in any measure). To this end we develop and study …

Sensitivity Anaylsis And Detectability For Magnetic Resonance Elastography, Catherine White Aug 2012

Sensitivity Anaylsis And Detectability For Magnetic Resonance Elastography, Catherine White

All Dissertations

This thesis is for a sensitivity analysis of magnetic resonance elastography, a hybrid imaging technique used in early-stage cancer screening. To quantitatively analyze the sensitivity, we introduce a notion of detectability, which is dened as a relative amplitude
drop in a small sti tumor region. This analysis is accomplished in both the full elastic and viscoelastic models and compared with that of the simpler scalar model which is frequently used in the actual application.
Some of the highlights are 1) a useful formula for detectability in terms of physical parameters, which will help the design of experiments; 2) the discrepancy …

A New Civics In The Digital Age: Connecting Online And Offline Activism In Lithuania, Liepa Gust

All Dissertations

Political participation is critical for the legitimacy of democracy, yet the majority of Lithuanians refrain from participating 20 years after the restoration of independence. Low rates of participation have been reinforced by adverse mass beliefs, including deep-rooted mistrust and political powerlessness. Given that the development of civic culture in a democratic Lithuania is occurring simultaneously with the spread of new information and communication technologies, Lithuania serves as an interesting case study of the potential of online spaces for facilitating participation. Empirical knowledge regarding the relationships between online engagement, civic attitudes, and offline activism would strengthen campaigns to promote democracy through …

The Influence Of Flagship Species On In Situ And Ex Situ Wildlife Tourists' Connection To Wildlife And Pro-Conservation Behaviors, Jeffrey Skibins Aug 2012

The Influence Of Flagship Species On In Situ And Ex Situ Wildlife Tourists' Connection To Wildlife And Pro-Conservation Behaviors, Jeffrey Skibins

All Dissertations

Annually, millions of tourists visit natural areas and zoos primarily to view flagship species such as lions and elephants. Venues rely on the inherent charisma of these species to increase visitation and anchor conservation efforts. Expected visitor outcomes from the use of flagships include raised levels of awareness and pro-conservation behaviors. However, the role of flagships in wildlife tourism has been criticized for not delivering conservation benefits for species of interest or biodiversity, and producing negative site impacts. Furthermore, little is known about how the connection to a species influences conservation behaviors. This dissertation addresses this gap in knowledge by …

The Power Of Thermonuclear Supernovae After One Year, Ginger Bryngelson Aug 2012

The Power Of Thermonuclear Supernovae After One Year, Ginger Bryngelson

All Dissertations

Type Ia supernovae (SNe Ia), the thermonuclear explosion of a white dwarf, shape our understanding of the expansion of the universe with the use of their uniformity in distance determinations. Powered by radioactivity synthesized in the explosion, they fade slowly over hundreds of days. Sometime after 200 days, the continually expanding ejecta allows γ-rays from 56 Ni and 56 Co decays to escape, and soon any radioactive power contributing to lighting up the SN comes from positrons formed in 19% of 56 Co
decays.
While at first it seemed that positrons escaped through the thinning ejecta, it has become apparent …

Avian Phenology, Climate, And Land-Use Conservation Assessed At Broad Spatial And Temporal Scales Using Interdisciplinary Approaches And Citizen Science, Jason Courter Aug 2012

Avian Phenology, Climate, And Land-Use Conservation Assessed At Broad Spatial And Temporal Scales Using Interdisciplinary Approaches And Citizen Science, Jason Courter

All Dissertations

Current natural resource challenges include global alteration of land cover, loss of biodiversity, impacts from increasing demands for agricultural products, and climate change. Birds are often used to assess the effects of ecological stressors because they are sensitive to environmental changes, ubiquitous and charismatic, and long-term monitoring programs have been in place for more than a century. I demonstrate the effects of climate change on avian migration and nesting dates and the potential value of using interdisciplinary approaches and citizen science to address contemporary ecological challenges. I examine Ruby-throated Hummingbird (Archilochus colubris) migration in the eastern United States from 1880-2010 …

Propagation Of Uncertainty In Light-Frame Wood Buildings, Seyed Masood Hassanzadehshirazi Aug 2012

Propagation Of Uncertainty In Light-Frame Wood Buildings, Seyed Masood Hassanzadehshirazi

All Dissertations

Light-frame wood construction is the most common form of construction for residential and low-rise commercial buildings (e.g. hotels and motels) in North America. In these buildings, shearwalls are the primary systems resisting lateral loads induced by earthquakes and winds. Past earthquake events have revealed that the structural performance of nominally identical light-frame wood buildings varied significantly. Although much research has been conducted investigating the uncertainty in the performance of wood shearwalls and buildings under earthquake loading, the focus of many of these studies was on the uncertainty due to the earthquake motions, referred as earthquake-to-earthquake uncertainty, the influences of variability …

A Novel Haptic Simulator For Evaluating And Training Salient Force-Based Skills For Laparoscopic Surgery, Ravikiran Singapogu Aug 2012

A Novel Haptic Simulator For Evaluating And Training Salient Force-Based Skills For Laparoscopic Surgery, Ravikiran Singapogu

All Dissertations

Laparoscopic surgery has evolved from an 'alternative' surgical technique to currently being considered as a mainstream surgical technique. However, learning this complex technique holds unique challenges to novice surgeons due to their 'distance' from the surgical site. One of the main challenges in acquiring laparoscopic skills is the acquisition of force-based or haptic skills. The neglect of popular training methods (e.g., the Fundamentals of Laparoscopic Surgery, i.e. FLS, curriculum) in addressing this aspect of skills training has led many medical skills professionals to research new, efficient methods for haptic skills training.
The overarching goal of this research was to demonstrate …

Camera Creatures: Rhetorics Of Light And Emerging Media, Anthony Collamati Aug 2012

Camera Creatures: Rhetorics Of Light And Emerging Media, Anthony Collamati

All Dissertations

Camera Creatures addresses the new media landscape in which cameras, in most situations, outnumber pens. The dissertation argues that despite the accessibility and power of imagemaking devices, there persists in the humanities and social sciences a hesitation to engage the possibilities for composing with optical media. A number of factors contributing to this trend are addressed, including the preference for image analysis over imagemaking practices, persistent assumptions of the camera's mechanical objectivity, and a tendency to teach visual invention as collage. As a counter-measure, a proposal is made for investment in the mediation of light, or 'photonic rhetorics.' To explore …

Assessing Maasai Attitudes And Perceptions Toward Vultures: A Case Study Of Resident Maasai Around Maasai Mara National Reserve, Kenya., Eric Reson Aug 2012

Assessing Maasai Attitudes And Perceptions Toward Vultures: A Case Study Of Resident Maasai Around Maasai Mara National Reserve, Kenya., Eric Reson

All Theses

The vulture population is declining globally, a situation that is more acute in the Maasai Mara region of Kenya where studies report over 60% decline in the last few years, resulting primarily from loss of habitat and poisoning by the Maasai pastoralist. This rate of decline is devastating and will result in the extinction of vultures in the region. Given that the causes of the decline are as a result of detrimental human activities, it is important to understand the Maasai attitude and perception toward vultures, particularly factors that determine their behavior to favor or oppose vulture conservation. In this …

An Electromagnetic Energy Harvester For Powering Consumer Electronics, Xiyuan Liu Aug 2012

An Electromagnetic Energy Harvester For Powering Consumer Electronics, Xiyuan Liu

All Theses

This thesis introduces an electromagnetic vibratory energy harvester to power consumer electronics by generating electricity from the strides taken during walking or jogging. The harvester consists of a magnetic pendulum oscillating between two fixed magnets. The pendulum behaves similar to a rotor in a DC generator, while the fixed magnets, which are poled opposite to the pendulum, provide magnetic restoring forces similar to mechanical springs. When attached to a person's arm, the swinging motion subjects the magnetic pendulum to base excitations. Consequently, the pendulum oscillates near a stator which has three poles of wound copper coils. The motion of the …
