Inverse Limits With Upper Semi-Continuous Set Valued Bonding Functions: An Example, Christopher David Jacobsen

Masters Theses

"While there is a wealth of information pertaining to inverse limits with single valued bonding maps, comparatively little is known about inverse limits with upper semi-continuous set valued bonding functions. In order to add somewhat to the communal knowledge on the subject, this paper provides an example of an inverse limit with a single upper semi-continuous set valued bonding function. It is then shown that the space is a continuum, and its structure is examined via its arc components and through various of its properties, such as dimension and decomposability"--Abstract, page iii.

Stability Of Streambanks Subjected To Highly Variable Streamflows: The Osage River Downstream Of Bagnell Dam, Kathryn Nicole Heinley

Masters Theses

"Streambank erosion of the Osage River downstream of Bagnell Dam is naturally-occurring; however, it may be significantly worsened due to releases made from the dam to generate hydropower. In this study, six typical outflow release patterns from Bagnell Dam were evaluated to determine their effects, if any, on the stability and the rate and amount of erosion of the banks of the Osage River.

The Bank Stability and Toe Erosion Model (BSTEM), version 5.2, was used to carry out the erosion and stability calculations. The model was validated by using data from another study and comparing the results from BSTEM …

Resistance Switching In Electrodeposited Magnetite Thin Films, Samantha Glen Matthews

Masters Theses

"The resistance switching phenomenon has been extensively studied in metal oxide thin films for its applications in the non-volatile memory industry. The research presented here focuses on magnetite thin films which have been electrodeposited onto gold-sputtered glass substrates via the electrochemical reduction of a Fe(III)-triethanolamine complex in aqueous alkaline solution. Magnetite was chosen for its usefulness in read/write memory applications, its high Curie temperature, its metal-to-insulator (Verwey) transition, and its half-metallic character and attendant spintronic properties. Resistance switching behavior caused by a reversible redox reaction at the anode was observed in the films, demonstrating that electrodeposited films show the same …

Analysis Of Eurycea Hybrid Zone In Eastern Missouri, Bonnie Jean Beasley

Masters Theses

"Evolutionary mechanisms are often difficult to observe in action because evolution generally works slowly over time. Hybrid zones provide a unique opportunity to observe many evolutionary processes, such as reinforcement, because of the rapid changes that tend to occur in these zones. Salamanders provide an ideal model for examining the rapid changes in populations that result from hybridization because many closely-related species lack reproductive barriers. In Missouri, a well-documented hybridization zone exists among the two subspecies Eurycea longicauda longicauda (long-tailed salamander) and E. L. melanopleura (dark-sided salamander). These salamanders inhabit caves, limestone creek beds, and abandoned mine shafts. A closely …

Analysis Of The Theta-D Filter As Applied To Hit-To-Kill Interceptors And Satellite Orbit Determination, Michael W. Dancer

Masters Theses

"When designing feedback control systems, there is often a need for estimation methods that provide system information that is not readily available via sensors placed within the system. In many cases a sensor that measures a particular system state either does not exist or is prohibitively expensive. In addition, all realistic systems contain some degree of nonlinearity. This thesis focuses on two such cases: missile guidance with bearings-only measurements and GPS satellite orbit determination. In each case, a new nonlinear filter, the [theta]-D method, is used and evaluated for its performance in providing the necessary estimation. To aid the filter …

Representation And Validation Of Domain And Range Restrictions In A Relational Database Driven Ontology Maintenance System, Patrick Garrett. Edgett

Masters Theses

"An ontology can be used to represent and organize the objects, properties, events, processes, and relations that embody an area of reality [1]. These knowledge bases may be created manually (by individuals or groups), and/or automatically using software tools, such as those developed for information retrieval and data mining. Recently, the National Science Foundation funded a large collaborative development project for the semi-automated construction of an ontology of amphibian anatomy (AmphibAnat [2]). To satisfy the extensive community curation requirements of that project, a generic, Web-based, multi-user, relational database ontology management system (RDBOM [3]) was constructed, based upon a novel theoretical …

For comprehensive validation of the driving simulator, a framework is proposed which is demonstrated using a fixed-base driving simulator. Objective and subjective evaluations were conducted, and validation of the driving simulator was performed at specific locations and along the highway. Field data were collected for a partial lane closure using a global positioning system (GPS) along the work zone and supplemented with video recordings of traffic data at specific locations …

Quantification Of Channel Performance And Development And Characterization Of Small Magnetic Field Probes, Surbhi Mittal

Masters Theses

"This thesis presents a new approach to quantifying channel performance using a transmitter waveform and dispersion penalty (TWDP) with frequency domain S-parameter data. Initially TWDP was defined to characterize the performance of a transmitter in optical links. More recently its use has been extended to include the quantification of channel performance, especially in high-speed copper links. This project focused mainly on channel characterization. Instead of using the time-domain oscilloscope measurements involved in the original approach, it proposes a new method that relies on frequency-domain S-parameter data obtained either from measurements or simulations. It included a parametric study of TWDP with …

Optimization Of Parameters And Study Of Kinetics In Lactulose Production By Lactose Isomerization Using Strong Basic Anion Exchange Resin, Arvind Nanduri

Masters Theses

"In this work, an experimental design was employed to investigate the effects of different operating conditions on the isomerization of lactose to lactulose by using strong basic anion exchange resin (AMBERLITE-IRA 402). Temperature, resin/lactose mass ratio and pH were considered to be the three factors affecting the conversion of lactose. Box-Behnken design was then used to optimize the operating conditions for maximum response and also to study the various interaction and main effects of the factors. The analysis of variance (ANOVA) of the experimental data showed a high correlation coefficient R² (0.99) and a low root mean square error (2.84) …

Modeling And Analysis Of High-Speed Sources And Serial Links For Signal Integrity, Siming Pan

Masters Theses

"As the computer and electronics industry moves towards higher data rates, signal integrity and electromagnetic interference (EMI) problems always present challenges for designers for high-speed data communication systems. To characterize the entire link path between transmitters and receivers, accurate models for sources, passive link path (such as traces, vias, connectors, etc), and terminations should be built before simulations either in frequency or time domain. Due to the imperfection of model, data corrections are preferred before time-domain simulations to ensure stability. Moreover, data obtained from models should be compared with measurement results to judge the level of agreement for validations. This …

Contribution-Based Priority Assessment In A Web-Based Intelligent Argumentation Network For Collaborative Software Development, Maithili Satyavolu

Masters Theses

"Decision making is an important aspect of the collaborative software development process which usually involves complex process of conflict resolution. Stakeholders approach decision making process from multiple perspectives and their priorities play a vital role in it. The priority assessment methods used in the argumentation process so far are usually static. Priorities remain constant throughout the decision making process. In order to make the collaborative system more closely replicate real-world scenarios, this work incorporates dynamic priority assessment into a web-based collaborative system which is based on intelligent computational argumentation. It evaluates priorities dynamically for each cycle of decision process based …

Determining The R Values For 12 Inch Deep Z-Purlins And Girts With Through-Fastened Panels Under Suction Loading, Kaye Dee Wibbenmeyer

Masters Theses

"Designing purlins for roof systems attached to through-fastened panels has been a subject well researched in the past. The current design specification uses a simplified approach to the designing of these members where the fully braced moment capacity of such members is multiplied by a reduction factor, commonly referred to as the R-value. This value represents the point in between the fully braced and fully unbraced member behavior. However, the current AISI Specification, S100, only contains R-values for purlins and girts up to 11.5 inches in depth. Since manufacturers are now rolling sections up to 12 inches deep, two confirmatory …

Corrosion Resistance Of Enamel-Coated Steel Reinforcement For Concrete, Charles Robert Werner

Masters Theses

"Originally developed to enhance the bond between concrete and steel, reactive enamel coatings have shown great promise in protecting steel from corrosive environments. However, the corrosion resistance of the material has not yet been tested beyond 40 days. Moreover, when the material was tested, it was applied to smooth steel pins, not deformed steel bars which are commonly used in reinforced concrete structures. Therefore, this study focused on the corrosion resistance of three different enamel coatings, along with a standard epoxy coating, each of which were applied to both smooth and deformed steel bars and included both short-term and long-term …

Synthesis And Characterization Of Microspheres For Controlled Release, Gurpartap Singh Sandhu

Masters Theses

"Synthetic hydroxyapatite (HAp, (Ca₁₀(PO₄)₆(OH)₂) has always been of interest in medical applications because of its similarities to inorganic bone matrix. It has been used in biomedical applications for bone repair and substitution due to its biocompatibility. However, there are some differences in the stoichiometry, composition, and mechanical properties of human bone as compared to pure HAP. HAp particles have been successfully used as drug delivery carriers which deliver the drug to the affected part of the body and the remaining apatite gets degraded by the physiological processes in the body. In the present work, emphasis was on developing mechanically stronger …

Nonlinear Finite Element Formulation Of The Soil Structure Interaction Through Two Parameter Foundation Model, Taraka Ravi Shankar Mullapudi

Masters Theses

"The response of shallow and raft foundations is having a significant importance due to its complex behavior because of the semi-infinite soil media. Winkler's model is the simplest model to deal with the structure and soil. The Winkler model represents the foundation reaction as proportional to the soil displacement at a particular point, which results in the elasticity of the soil being the only parameter in consideration. But in reality the soil cohesiveness is having a significant contribution in soil structure interaction, and therefore the consideration of coupling effects of Winkler springs need to be accounted. Most of the existing …

Experimental Study On Thermal Treatment Of Used Printed Wiring Boards (Pwbs), Xiangjun Zuo

Masters Theses

The availability of cheaper and better electronic products as a result of the rapid innovation in technology in past decades has driven the production of e-waste forward. Printed wiring board (PWB) is a component made of one or more layers of insulating material with electrical conductors. The existing processes of recycling PWBs use pyrometallurgical or hydrometallurgical methods, which generate atmospheric pollution. Green recycling has obvious benefits to decrease the amount of PWBs. Green recycling includes two features, 1) little or zero pollution of toxic gases and heavy metals, and 2) efficient (quick and economical) recycling.

The aim of this work …

Maskless Additive Manufacturing Of Micro Structures By Laser Sintering Of Nanoparticles, Vivekram Ramanathan

Masters Theses

"The focus of this study was to investigate an alternate microfabrication process of sintering nanoparticles using a patterned laser light to generate two dimensional (2D) and three dimensional (3D) geometries. With trends of producing electronic and medical devices using cheaper and faster technologies, a new procedure was developed to deposit and bond miniature patterns of silver nanoparticles onto silicon substrates.

The process consists of spraying silver nanoparticles onto the substrate while a patterned or modulated laser beam is focused onto the sprayed nanoparticles. These nanoparticles exposed under the modulated laser light undergo partial melting or sintering and adhere to the …

Neuroscience And The Free Exercise Of Religion, Steven Goldberg

Georgetown Law Faculty Publications and Other Works

Recent developments in neuroscience that purport to reduce religious experience to specific parts of the brain will not diminish the fundamental cultural or legal standing of religion. William James debunked this possibility in The Varieties of Religious Experience (1902) when he noted that “the organic causation of a religious state of mind” no more refutes religion than the argument that scientific theories are so caused refutes science. But there will be incremental legal change in areas like civil commitment where judges must sometimes distinguish between mental disorder and religious belief. The paradox is that the ecstatic religious experience of unorthodox …

Top 10 Law School Home Pages Of 2009, Roger Skalbeck

Georgetown Law Faculty Publications and Other Works

The website home page represents the virtual front door for any law school. It’s the place many prospective students start in the application process. Enrolled students, law school faculty and other employees often start with the home page to find classes, curricula and compensation plans. Home page content changes constantly. Deciding which home pages are good is often very subjective. Creating a ranking system for “good taste” is perhaps impossible.

The ranking report "Top 10 Law School Home Pages of 2009" includes a tabulation of fourteen objective design criteria to analyze and rank 195 law school home pages. The intent …

The Shadow Of State Secrets, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

The shadow of state secrets casts itself longer than previously acknowledged. Between 2001 and 2009 the government asserted state secrets in more than 100 cases, while in scores more litigants appealed to the doctrine in anticipation of government intervention. Contractor cases ranged from breach of contract, patent disputes, and trade secrets, to fraud and employment termination. Wrongful death, personal injury, and negligence suits kept pace, extending beyond product liability to include infrastructure and services, as well as conduct of war. In excess of fifty telecommunications suits linked to the NSA warrantless wiretapping program emerged 2006-2009, with the government acting, variously, …

Closing The Legislative Experience Gap: How A Legislative Law Clerk Program Will Benefit The Legal Profession And Congress, Dakota S. Rudesill

Georgetown Law Faculty Publications and Other Works

Most federal law today is statutory or rooted in statutes, which are created through a complicated process best understood through work experience inside legislatures. This article demonstrates that America’s most influential lawyers are not getting it. My new empirical analysis of the work experience of the top 500 lawyers nationwide as ranked by Lawdragon.com finds that work experience in legislative bodies is dramatically less common among the profession’s leaders than is formative work experience in courts, government executive agencies, private practice, and academe. This article continues the empirical study of the professional experience of the legal profession’s elite published in …

Finding The Middle Ground In Collection Development: How Academic Law Libraries Can Shape Their Collections In Response To The Call For More Practice-Oriented Legal Education, Leslie A. Street, Amanda M. Runyon
