Online Diagnosis Of Diabetes With Twitter Data, Farheen Ali

Masters Theses

"Innovation in technology enables people to communicate, share information and look for their needs by just sitting in rooms and going through some clicks. While social media has played a very important role in connecting people worldwide, its potential has stretched beyond the innovative idea of connecting people through their social networks. While many thought there was no meeting point for the healthcare sector and social media, it was a surprise when research and innovations have shown that social media could lay a very significant role in the health care sector.

Research has been done in developing models that could …

Numerical Study Of Upstream And Downstream Regions Of One Dimensional Detonation Wave In A Dusty Gas Medium, Shubhadeep Banik

Masters Theses

"In detonative combustion very high temperatures are attained by the burned gases. As a result, a large amount of thermal energy is produced during the combustion process. This heat can affect the state of the unburned fuel through radiation of heat from the burned gases. In this study a one-dimensional model was deemed appropriate to gain insight into the fundamental structure of the detonation wave. In this model, the detonation wave divides the fluid stream into an upstream region, consisting of fuel and oxidant, and a downstream region, consisting of burned gases. A set of computer programs, some developed during …

Evaluation Of Preformed Particle Gel Treatment Using Homogeneous And Heterogeneous Models, Hilary Ogochukwu Elue

Masters Theses

"This research investigates the effects of preformed particle gel (PPG) in remedying the problems of excess water production and low oil recovery of heterogeneous reservoirs by placing the PPG in the high-permeability layer, thus diverting displacing brine to the unswept low permeability layer. This investigation was completed with three tasks.

The first task was to evaluate the PPG swelling kinetics and strength as a function of concentration of brine. The result of this task indicate that PPG prepared with low concentration of brine swells more, becomes weaker, more deformable than PPG prepared with high concentration of brine.

The second task …

Comprehensive Benefits Of Green Roofs, Madison R. Gibler

Masters Theses

"Green infrastructure uses vegetation, soils, and natural processes to manage water and create healthier urban environments, providing traditional roof services and alternative stormwater management technologies. Other benefits and impacts are not yet fully understood or valued. Research conducted assesses specific stormwater benefits of green roofs, providing information on nutrient leaching from media; and analyzes potential energy benefits through side-by-side comparisons of full-scale white, traditional black rubber, and green roofs in the mid-continent Missouri climate. Roofing media selection impacted leaching of nutrients, suspended solids, and organic carbon from the tested green roof media. Thermal properties were investigated at the building level, …

Characterizing The Influence Of Carbon On The Flowrate And Disinfection Efficacy Of Household Ceramic Water Filters, Jessie Yvonne Hahn

Masters Theses

"Drinking water contamination is a major cause of disease in developing countries. Point of Use (POU) water treatment technologies generally have low initial cost and allow rapid availability of improved water. Ceramic pot filters (CPFs) are a POU water source treatment technology which filter water by gravity through a porous ceramic media. Some filters in use contain carbon remnants left from the fugitive pore former as a dark carbon core. Using disk-shaped experimental ceramic filters produced in the lab to have varying levels of carbon, the percent carbon present was measured and a visual analysis method was developed to determine …

Spatial And Temporal Modulation Of Heat Source Using Light Modulator For Advanced Thermography, Arvindvivek Ravichandran

Masters Theses

"Thermography is a Non-Destructive Testing (NDT) method that has found increasing use in industry and research. It has the advantages of being non-contact and be able to interrogate a large surface simultaneously. Active thermography using flash lamps as heat source has been demonstrated for identifying blind holes and delamination in composites. Despite these advancements, active thermographic approach fails to defects like cracks. Under uniform illumination heat flow is predominantly 1D and can easily circumvent a narrow feature. This can be overcome by using a focused light/laser source onto the surface to impose a 3D heat flux. The disadvantage is that …

The Effects Of Physical Flash Hole Deviations On Factory-Grade Rifle Ammunition, Nicolaas Martin Schrier

Masters Theses

"The objective of this research is to determine the effect of dimensional and positional changes of the primer flash hole on the performance of factory-grade rifle ammunition. The studied variables were flash hole diameter, offset from center, and orientation of the offset in the primer pocket. Cartridge performance was quantified by measuring muzzle velocity, chamber pressure, and target grouping size (precision).

Five different flash hole diameters were tested for both the Remington .223 and Winchester .308 calibers: 1.4mm, 2.0mm (the Fiocchi standard), 2.4mm, 2.8mm, and 3.0mm. Each diameter was tested at three offsets: centered (no offset), 0.5mm from center, and …

This paper discusses both CO₂ miscible and immiscible flooding mechanisms and offers some guidelines for flooding operations. New developments in MMP determination are also introduced.

This research is based on a summary of field data from 134 CO₂ projects in the U.S. Several numerical methods have been applied for data cleaning. After cleaning, data from 128 projects have been analyzed and correlated. Carbonate reservoirs and sandstone reservoirs are the two …

Optimum Acquisition And Processing Parameters For Multichannel Analysis Of Surface Waves Using 3d Electrical Resistivity Tomography As Control, Uchenna Chibuzo Nwafor

Masters Theses

"Multichannel Analysis of Surface Waves (MASW) and Electrical Resistivity Tomography (ERT) data were acquired in the Newburg, Missouri with the goal of determining optimum MASW acquisition parameters. Users of the MASW tool generally state that greater geophone intervals and greater shot-to-receiver offsets provide for more accurate results. The objective was to determine if this "rule of thumb" applies in karst terrain.

ERT data were acquired along four traverses with eighty-four (84) electrodes at five feet spacing with SuperSting R8 Resistivity System using dipole- dipole array. The data were processed using Earth Imager to generate 2-D resistivity inversion and thereafter, Voxler …

Design And Implementation Of Low Complexity Wake-Up Receiver For Underwater Acoustic Sensor Networks, Ming Yue

Masters Theses

"This thesis designs a low-complexity dual Pseudorandom Noise (PN) scheme for identity (ID) detection and coarse frame synchronization. The two PN sequences for a node are identical and are separated by a specified length of gap which serves as the ID of different sensor nodes. The dual PN sequences are short in length but are capable of combating severe underwater acoustic (UWA) multipath fading channels that exhibit time varying impulse responses up to 100 taps. The receiver ID detection is implemented on a microcontroller MSP430F5529 by calculating the correlation between the two segments of the PN sequence with the specified …

Bed management is key to the effective delivery of high-quality and low-cost healthcare. An efficient utilization of beds requires a detailed understanding of the hospital's operational behavior. It is necessary to understand the behavior of a hospital in order to make necessary adjustments to its resources, and policies, which can improve patient's access to care. The aim of this research was to develop a discrete event simulation to assist in planning and staff scheduling decisions. …

Ambiguous-Purpose Statements Of Children And Other Victims Of Abuse Under The Confrontation Clause, Paul F. Rothstein

Georgetown Law Faculty Publications and Other Works

The author examines in this paper two kinds of ambiguous-purpose out-of-court statements that are especially problematic under current Confrontation law--problematic in ways that we hope will be solved directly or indirectly by the Supreme Court when it renders its decision in Ohio v. Clark. The statements he examines are:

(1) Statements made by abused children concerning their abuse, for example to police, physicians, teachers, welfare workers, baby sitters, or family members, some of whom may be under a legal duty to report suspected abuse to legal authorities. At least some of these statements will be directly addressed by the …

The Romantic Author And The Romance Writer: Resisting Gendered Concepts Of Creativity, Rebecca Tushnet

Georgetown Law Faculty Publications and Other Works

Dominant narratives of creativity regularly expect female-associated forms of creativity to be provisioned naturally without need for the economic incentives provided by exclusive rights, just like housework and childcare. Even as the concept of Romantic authorship has come under sustained analytic assault, its challengers often look elsewhere–to the kinds of creativity in which men are more likely to participate–to find models of situated, always-influenced authorship. In this chapter, I examine one variant of the problem, in which certain arguments about copyright discount the value of forms that are predominantly produced and enjoyed by women. But creative works in these oft-denigrated …

A Mask That Eats Into The Face: Images And The Right Of Publicity, Rebecca Tushnet

Georgetown Law Faculty Publications and Other Works

In their eagerness to reward celebrities for the power of their “images,” and to prevent other people from exploiting those images, courts have allowed the right of publicity to distort the First Amendment. The power of the visual image has allowed courts to create an inconsistent, overly expansive regime that would be easily understood as constitutionally unacceptable were the same rules applied to written words as to drawings and video games. The intersection of a conceptually unbounded right with a category of objects that courts do not handle well has created deep inconsistencies and biases in the treatment of visual …

High Technology, Consumer Privacy, And U.S. National Security, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

Documents released over the past year detailing the National Security Agency’s (“NSA”) telephony metadata collection program and interception of international content under the Foreign Intelligence Surveillance Act (FISA) implicated U.S. high technology companies in government surveillance. The result was an immediate, and detrimental, impact on U.S. corporations, the economy, and U.S. national security.

The first Snowden documents, printed on June 5, 2013, revealed that the government had served orders on Verizon, directing the company to turn over telephony metadata under Section 215 of the USA PATRIOT Act. The following day, The Guardian published classified slides detailing how the NSA had …

Human Rights Thinking And The Laws Of War, David Luban

Georgetown Law Faculty Publications and Other Works

In a significant early case, the ICTY commented: “The essence of the whole corpus of international humanitarian law as well as human rights law lies in the protection of the human dignity of every person…. The general principle of respect for human dignity is . . . the very raison d'être of international humanitarian law and human rights law.”

Is it true that international humanitarian law and international human rights law share the same “essence,” and that essence is the general principle of respect for human dignity? Is it true that, in the words of Charles Beitz, humanitarian law is …

Time-Mindedness And Jurisprudence, David Luban

Georgetown Law Faculty Publications and Other Works

Analytic jurisprudence often strikes outsiders as a discipline unto itself, unconnected with the problems that other legal scholarship investigates. Gerald Postema, in the article to which this paper responds, traces this “unsociability” to two narrowing defects in the project of analytic jurisprudence: (1) from Austin on, it has concerned itself largely with the analysis of professional concepts, without connecting that analysis with other disciplines that study law, nor with the history of jurisprudence itself, nor with general philosophy; (2) analytic jurisprudence studies only time-­‐slice legal systems, rather than legal systems unfolding in history. He argues that a time-­‐slice legal system …

Substitute Arguments In Constitutional Law, Louis Michael Seidman

Georgetown Law Faculty Publications and Other Works

In this article, I argue that that substitution is crucial to our practice of constitutional law. Of course, if one wished, one could easily extend the domain of substitution beyond these boundaries. Substitute arguments are an important aspect of law more generally and, indeed, of life. I have nonetheless chosen to limit my discussion to constitutional substitution because, I believe, overt discussion of substitution in this particular area illuminates important aspects of our constitutional regime-–aspects that substitution itself regularly obscures. To put my central point directly, I hope to show that constitutional law amounts to one, giant substitute argument.

Ex Post Modernism: How The First Amendment Framed Nonrepresentational Art, Sonya G. Bonneau

Georgetown Law Faculty Publications and Other Works

Nonrepresentational art repeatedly surfaces in legal discourse as an example of highly valued First Amendment speech. It is also systematically described in constitutionally valueless terms: nonlinguistic, noncognitive, and apolitical. Why does law talk about nonrepresentational art at all, much less treat it as a constitutional precept? What are the implications for conceptualizing artistic expression as free speech?

This article contends that the source of nonrepresentational art’s presumptive First Amendment value is the same source of its utter lack thereof: modernism. Specifically, a symbolic alliance between abstraction and freedom of expression was forged in the mid-twentieth century, informed by social and …

Understanding Impurities In Copper Electrometallurgy, Paul Laforest

Masters Theses

"This work involves examining two industrial reports of methods to handle impurities in copper electrowinning and electrorefining. The first part evaluates the addition of Hydrostar, Cyquest N-900, DXG-F7, and Guartec EW to copper electrowinning electrolyte to affect MnO₂ deposition on coated titanium anodes (CTAs). The second part examines the effects of anode chemistry and thiourea addition on the ductility of electrorefined copper starter sheet.

In part one, a laboratory cell was used to simulate a short cycle electrowinning cell via chronopotentiometric operation with an IrO₂-Ta₂O₅ CTA at 40⁰C. A cyclic voltammetric sweep was applied …

Damage Detection Through Acoustic Emission Of Fracture Processes In Concrete Masonry Units, John Alexander Cain

Masters Theses

"Masonry structures are vulnerable to earthquakes; their brittleness and discontinuous formation make them susceptible to collapse. In the event of an emergency, this could be detrimental and perhaps fatal. The area of Structural Health Monitoring (SHM) is focused on understanding the behavior of structures for the sake of safety and predicting their longevity. One applicable technique to monitor this behavior is Acoustic Emission (AE). Acoustic Emissions are transient elastic waves released as microcracks nucleate from stress intensities, coalesce into cracks and then accumulate as damage. AE monitoring is a favorable method because it is capable of detecting cracking from within …

A Tale Of Two Diseases: Mental Illness And Hiv/Aids, Lawrence O. Gostin

Georgetown Law Faculty Publications and Other Works

There have been dramatic advances in the treatment of HIV/AIDS. Whereas HIV was once a dire diagnosis, today it is treatable, and individuals who receive early and consistent treatment can expect to live a normal lifespan. Why has the scientific community made the same strides with mental illness? When I was the Legal Director of the National Association of Mental Health in the United Kingdom in the 1980s, major mental illnesses were primarily treated with powerful antipsychotics, such as haloperidol, that carried the debilitating side effects of tardive dyskinesia—involuntary movements of the tongue, lips, face, trunk, and extremities. When I …

Red-Teaming Nlw: A Top Ten List Of Criticisms About Non-Lethal Weapons, David A. Koplow

Georgetown Law Faculty Publications and Other Works

Critics of non-lethal weapons (NL W) have asserted numerous complaints about the concepts, the Department of Defense research and development efforts, and the pace of innovation in the field. These critiques challenge the cost of the programs, their consistency with international law, the adverse public reaction to some of the devices, and the dangers of proliferation, among other points. This article summarizes the various assessments, in form of a "top ten list" of criticisms, and evaluates their weight. The author concludes that some of these points of objection have merit, but overall, the NLW enterprise is worthy of continuation and …

Free To Be You And Me? Copyright And Constraint, Rebecca Tushnet

Georgetown Law Faculty Publications and Other Works

Joseph P. Fishman’s Creating Around Copyright advances a provocative thesis: some restrictions on creativity can spur the development of additional creative solutions, and (some level of) copyright might be one of those restrictions. If Picasso was right that “forcing yourself to use restricted means is the sort of restraint that liberates invention,” then being forced by law to use restricted means might do the same thing, ultimately leading to more varied and thus more valuable works.

At the outset, it’s important to know the baseline against which we ought to evaluate Fishman’s claims. Most copyright restrictionists, of whom I count …

Content, Purpose, Or Both?, Rebecca Tushnet

Georgetown Law Faculty Publications and Other Works

Most debates about the proper meaning of “transformativeness” in fair use are really about a larger shift towards more robust fair use. Part I of this short Article explores the copyright-restrictionist turn towards defending fair use, whereas in the past critics of copyright’s broad scope were more likely to argue that fair use was too fragile to protect free speech and creativity in the digital age. Part II looks at some of the major cases supporting that rhetorical and political shift. Although it hasn’t broken decisively with the past, current case law makes more salient the freedoms many types of …

Cable TV return path data made possible by current generation set-top boxes present a new opportunity to analyze household viewing behavior and recover household viewing preferences from it. This research develops a model of household viewing preference that supports quantifying a household's valuation for different categories of digital content within the constraints of the programs to which it subscribes. This study uses a data set of more than 1 million observations on households from a digital entertainment firm that offers basic and premium services. Our estimation is via a Bayesian hierarchical model that employs the Gibbs sampler. The results show …

Diffusion Of Innovations Of Videoconference Technology: An Instrumental Case Study Concerning Undergraduate Degree-Seeking Nontraditional Learners, Bruce G. Campbell

Theses and Dissertations

This applied dissertation is an instrumental case study based on diffusion of innovations theory designed to gather student opinions regarding videoconference (VC) technology use in facilitating courses to undergraduate degree-seeking nursing students. The author of diffusion of innovations theory, Rogers (2003), recommended that more qualitative studies be conducted in education. Rogers and Jain (1968) recommended these studies should be conducted from the aspect of “receivers of innovation diffusion” (p.1) to provide feedback instrumental to implementation of technological innovations in academe. Further, Rogers stated that multiple data points should be used during the process of trialing an innovation. Therefore, a current …
