An Autonomous Orbit Transfer Controller For The Nasa Magnetospheric Multiscale Satellite, Michael Borrelli Jan 2008

An Autonomous Orbit Transfer Controller For The Nasa Magnetospheric Multiscale Satellite, Michael Borrelli

Master's Theses and Capstones

With the ever more demanding goals of space exploration and research comes the need for more complex mission planning. Part of this complexity manifests itself in a satellite's orbit specifications. An increasing number of explorer missions call for a group of satellites to maneuver while arranged in a tightly controlled formation, or constellation. In order to maintain these constellations at immense distances from Earth, engineers must rely on feedback systems within the satellites' hardware. Controllers are created to manipulate the actuators, such as thrusters, and are therefore responsible for the economical use of fuel; overusing fuel can reduce a satellite's …


The Experimental Evolution Of Host Adaptation Of The Emerging Pathogen Burkholderia Cenocepacia, Crystal Nicole Ellis Jan 2008

The Experimental Evolution Of Host Adaptation Of The Emerging Pathogen Burkholderia Cenocepacia, Crystal Nicole Ellis

Master's Theses and Capstones

I investigated the ability of Burkholderia cenocepacia, an opportunistic bacterial pathogen, to adapt to a host. Studies have identified trade-offs associated with environmental adaptation, but few have investigated host adaptation. Consequently, I studied effects of adaptation by B. cenocepacia to onions (Allium cepa) on the ability to kill Caenorhabditis elegans. I hypothesized that adaptation to onions would reduce virulence in C. elegans. I evolved twelve populations of bacteria in onion tissue medium for 500 generations. Then, I quantified fitness differences between evolved and ancestral populations by direct competition, having developed molecular marking techniques to discriminate among competitors. Competitions revealed fitness …


Rapid Test Method For Determining Alkali-Silica Reactivity Expansion In Concrete And Aggregate, Douglas R. Pac Jan 2008

Rapid Test Method For Determining Alkali-Silica Reactivity Expansion In Concrete And Aggregate, Douglas R. Pac

Master's Theses and Capstones

The undesirable expansion of concrete due to a reaction between alkalis in the cement and reactive siliceous aggregates, known as alkali-silica reactivity (ASR), continues to be a world-wide problem. Current test methods for predicting ASR are either inaccurate because they are unrepresentative of field conditions or require long testing periods that become impractical for use in the field. Because of the rising interest to minimize distress caused by ASR, alternative methods must be considered.

A key factor in the prediction of ASR in concrete over time is the reactivity of the aggregate. In the present study, an attempt was made …


Molecular Targets Of 2,3,7,8-Tetrachlorodibenzo-P-Dioxin (Tcdd) Within The Zebrafish Ovary: Insights Into Tcdd-Induced Endocrine Disruption And Reproductive Toxicity, Tisha C. King Heiden, Craig Struble, Matthew L. Rise, Martin J. Hessner, Reinhold J. Hutz, Michael J. Carvan Iii Jan 2008

Molecular Targets Of 2,3,7,8-Tetrachlorodibenzo-P-Dioxin (Tcdd) Within The Zebrafish Ovary: Insights Into Tcdd-Induced Endocrine Disruption And Reproductive Toxicity, Tisha C. King Heiden, Craig Struble, Matthew L. Rise, Martin J. Hessner, Reinhold J. Hutz, Michael J. Carvan Iii

Mathematics, Statistics and Computer Science Faculty Research and Publications

TCDD is a reproductive toxicant and endocrine disruptor, yet the mechanisms by which it causes these reproductive alterations are not fully understood. In order to provide additional insight into the molecular mechanisms that underlie TCDD's reproductive toxicity, we assessed TCDD-induced transcriptional changes in the ovary as they relate to previously described impacts on serum estradiol concentrations and altered follicular development in zebrafish. In silico computational approaches were used to correlate candidate regulatory motifs with observed changes in gene expression. Our data suggest that TCDD inhibits follicle maturation via attenuated gonadotropin responsiveness and/or depressed estradiol biosynthesis, and that interference of estrogen-regulated …


Use Of Trees By The Texas Ratsnake (Elaphe Obsoleta) In Eastern Texas, Josh B. Pierce, Robert R. Fleet, Lance Mcbrayer, D. Craig Rudolph Jan 2008

Use Of Trees By The Texas Ratsnake (Elaphe Obsoleta) In Eastern Texas, Josh B. Pierce, Robert R. Fleet, Lance Mcbrayer, D. Craig Rudolph

Faculty Publications

We present information on the use of trees by Elaphe obsoleta (Texas Ratsnake) in a mesic pine-hardwood forest in eastern Texas. Using radiotelemetry, seven snakes (3 females, 4 males) were relocated a total of 363 times from April 2004 to May 2005, resulting in 201 unique locations. Snakes selected trees containing cavities and used hardwoods and snags for a combined 95% of arboreal locations. Texas Ratsnake arboreal activity peaked during July and August, well after the peak of avian breeding activity, suggesting arboreal activity involves factors other than avian predation.


Delta Function For An Affine Subspace, Jeremy Becnel Jan 2008

Delta Function For An Affine Subspace, Jeremy Becnel

Faculty Publications

The Kubo–Yokoi and Donsker delta functions are well known generalized functions in infinite dimensional distribution theory. In this paper we develop the delta function for an affine subspace and show that it is a generalization of the Kubo–Yokoi and Donsker delta functions. The Wiener– Itˆo expansion of the delta function for an affine subspace is also given.

Beating The Spin-Down Limit On Gravitational Wave Emission From The Crab Pulsar, Ligo Scientific Collaboration, Nelson Christensen, Jan 2008

Beating The Spin-Down Limit On Gravitational Wave Emission From The Crab Pulsar, Ligo Scientific Collaboration, Nelson Christensen,

Physics and Astronomy Faculty Work

We present direct upper limits on gravitational wave emission from the Crab pulsar using data from the first nine months of the fifth science run of the Laser Interferometer Gravitational-wave Observatory (LIGO). These limits are based on two searches. In the first we assume that the gravitational wave emission follows the observed radio timing, giving an upper limit on gravitational wave emission that beats indirect limits inferred from the spin-down and braking index of the pulsar and the energetics of the nebula. In the second we allow for a small mismatch between the gravitational and radio signal frequencies and interpret …


A Simple Model For Pulse Profiles From Precessing Pulsars, With Special Application To Relativistic Binary Psr B1913+16, Timothy Clifton, Joel M. Weisberg Jan 2008

A Simple Model For Pulse Profiles From Precessing Pulsars, With Special Application To Relativistic Binary Psr B1913+16, Timothy Clifton, Joel M. Weisberg

Physics and Astronomy Faculty Work

We study the observable pulse profiles that can be generated from precessing pulsars. A novel coordinate system is defined to aid visualization of the observing geometry. Using this system we explore the different families of profiles that can be generated by simple, circularly symmetric beam shapes. An attempt is then made to fit our model to the observations of relativistic binary PSR B1913+16. It is found that while qualitatively similar pulse profiles can be produced, this minimal model is insufficient for an accurate match to the observational data. Consequently, we confirm that the emission beam of PSR B1913+16 must deviate …

Really Leaving No Child Behind: How The Supreme Court's Student Speech Doctrine Compromises Modern Education Reform - And How It Can Use The In Loco Parentis Doctrine To Change It, Scott J. Street Jan 2008

Really Leaving No Child Behind: How The Supreme Court's Student Speech Doctrine Compromises Modern Education Reform - And How It Can Use The In Loco Parentis Doctrine To Change It, Scott J. Street

Richmond Journal of Law and the Public Interest

tudent speech" doctrine defined by Tinker in favor of an in loco parentis standard that defers to the expertise of school officials in maintaining a safe, effective, and orderly school environment. Contrary to what its critics assume, an in loco parentis standard would not give school officials carte blanche to violate their students' rights. It would, for example, prohibit school officials from discriminating against students on the basis of viewpoint. But as long as Tinker's student speech doctrine survives, efforts to improve our schools and prepare our children for the rigors of the twenty-first century will suffer. The in loco …


Finders Sleepers: Why Recent State Regulation Of Financial Intermediaries Should Rouse The Federal Government From Its Slumber, Jeffrey D. Chadwick Jan 2008

Finders Sleepers: Why Recent State Regulation Of Financial Intermediaries Should Rouse The Federal Government From Its Slumber, Jeffrey D. Chadwick

Richmond Journal of Law and the Public Interest

This comment argues that the current treatment of financial intermediaries in the capital-raising process is unresponsive to the changing landscape of the small business community. Not only does the SEC inadequately define the permissible role of a finder, recent legislation in Texas and South Dakota foreshadows the ills of a dual regulatory society. Rather than waiting for states to address the finder's dilemma on an ad hoc and inconsistent basis, the federal government should create an SEC-registered class of finders to facilitate capital formation and jumpstart a receding American economy. Part II examines the expanding role of financial intermediaries in …

Ground Motion Sensitivity Analyses For The Greater St. Louis Metropolitan Area, Ece Karadeniz Jan 2008

Ground Motion Sensitivity Analyses For The Greater St. Louis Metropolitan Area, Ece Karadeniz

Masters Theses

"Local site effects can play an important role in modifying the intensity of ground shaking and earthquake damage. The process of rock motion propagating through the soil column can be approximated using one-dimensional site response analyses. To evaluate the likely site response several input parameters are required. These include: thickness of the unconsolidated soil cap, shear wave velocity, unit density, dynamic soil properties, and acceleration time histories. Considerable uncertainty often exists in regards to these input parameters. In this study, the program Shake2000 was employed for site response analyses and sensitivity analyses were performed to determine how the uncertainties in …


Forecasting Using The T-Method, Parthiv Akshay Shah Jan 2008

Forecasting Using The T-Method, Parthiv Akshay Shah

Masters Theses

"The T-method is a technique developed by Genichi Taguchi to calculate an overall prediction based on the signal-to-noise ratio without the use of Gram-Schmidt orthogonalization. The Taguchi Methods, also known as robust design principles, is used to determine the optimal levels of control factors through planning and conducting experiments, and evaluating their results. The primary goal of Robust Design is to minimize variance in the presence of noise factors to achieve a robust process. T-Method is one of the techniques evolved from Taguchi Methods. This thesis illustrates the use of the T-method and outlines it steps using four forecasting case …


Cross-Layer Design Through Joint Routing And Link Allocation In Wireless Sensor Networks, Xuan Gong Jan 2008

Cross-Layer Design Through Joint Routing And Link Allocation In Wireless Sensor Networks, Xuan Gong

Masters Theses

"Both energy and bandwidth are scarce resources in sensor networks. In the past, the energy efficient routing problem has been extensively studied in efforts to maximize sensor network lifetimes, but the link bandwidth has been optimistically assumed to be abundant. Because energy constraint affects how data should be routed, link bandwidth affects not only the routing topology, but also the allowed data rate on each link, which in turn affects the lifetime. Previous research that focus on energy efficient operations in sensor networks with the sole objective of maximizing network lifetime only consider the energy constraint ignoring the bandwidth constraint. …


Designing And Evaluating A Russian Tagset, Serge Sharoff, Mikhail Kopotev, Tomaž Erjavec, Anna Feldman, Dagmar Divjak Jan 2008

Designing And Evaluating A Russian Tagset, Serge Sharoff, Mikhail Kopotev, Tomaž Erjavec, Anna Feldman, Dagmar Divjak

Department of Linguistics Faculty Scholarship and Creative Works

This paper reports the principles behind designing a tagset to cover Russian morphosyntactic phenomena, modifications of the core tagset, and its evaluation. The tagset and associated morphosyntactic specifications are based on the MULTEXT-East framework, while the decisions in designing it were aimed at achieving a balance between parameters important for linguists and the possibility to detect and disambiguate them automatically. The final tagset contains about 600 tags and achieves about 95% accuracy on the disambiguated portion of the Russian National Corpus. We have also produced a test set of tagging models and corpora that can be shared with other researchers.


Probabilistic Analysis Of Defect Tolerance In Asynchronous Nano Crossbar Architecture, Shikha Chaudhary Jan 2008

Probabilistic Analysis Of Defect Tolerance In Asynchronous Nano Crossbar Architecture, Shikha Chaudhary

Masters Theses

"Among recent advancements in technology, nanotechnology is particularly promising. Most researchers have begun to focus their efforts on developing nano scale circuits. Nano scale devices such as carbon nano tubes (CNT) and silicon nano wires (SiNW) form the primitive building blocks of many nano scale logic devices and recently developed computing architecture. One of the most promising nanotechnologies is crossbar-based architecture, a two-dimensional nanoarray, formed by the intersection of two orthogonal sets of parallel and uniformly-spaced CNTs or SiNWs. Nanowire crossbars offer the potential for ultra-high density, which has never been achieved by photolithography. In an effort to improve these …
