Computational Intelligence Methods In Wireless Sensor Networks, Raghavendra V. Kulkarni

Doctoral Dissertations

"Wireless sensor networks (WSNs) are networks of autonomous nodes that sense, compute and communicate in order to monitor an environment collectively. Ad hoc deployment, dynamic environment and resource constraints in nodes need to be considered while addressing WSN challenges such as deployment, localization, routing and scheduling. Adaptive mechanisms that exhibit intelligent behavior in complex and dynamic environments are desirable to address these challenges. The potential of computational intelligence ( CI) based approaches for addressing WSN challenges is investigated in this study. Contributions of this dissertation are in the following three areas: critical literature analysis, new architectures and approaches, and new …

Synthesis And Characterization Of Metal Decorated Bamboo Structured Carbon Nanotubes For Hydrogen Storage, Sean Charles Mickey

Doctoral Dissertations

"Although hydrogen has been considered as a viable alternative fuel, the storage systems used to contain the hydrogen must be improved for large scale use. A variety of conceivable storage options exist ranging from compressed gas, cryogenic liquid, chemical solid state storage, and adsorptive surfaces. Carbon nanotubes (CNTs) provide a potentially viable option for hydrogen storage applications as a high surface area, lightweight media for adsorptive storage, but do not efficiently store hydrogen at ambient temperatures. Metal hydrides, on the other hand, are able to store large weight percents of hydrogen in a chemical solid state, but generally have unfavorable …

Nmr Investigations Of Biomass-To-Fuel Conversions By Hydrothermal Processes, Wenjia Zhang

Doctoral Dissertations

"Biofuels have gained significant attention as the most promising alternative energy and fuel supply for the near future because of two dominant reasons: first, biofuels are environmentally friendly; and second, they afford a sustainable technology. Biofuels can be synthesized from biomass by several different processes, among which, hydrothermal conversion is considered to be more energy efficient. However, scientific efforts to improve hydrothermal biomass-to-fuel (HT-BTF) conversion efficiencies are severely limited because little is known about the salient reaction mechanisms and intermediates. This study is aimed at a better understanding of the hydrothermal biomass degradation kinetics by advanced NMR spectroscopy and, accordingly, …

Haart Drugs Induce Oxidative Stress And Mitochondrial Dysfunction In Blood-Brain Barrier, Kalyan Reddy Manda

Doctoral Dissertations

"The era of highly active antiretroviral therapy (HAART) has controlled AIDS and its related disorders considerably; however, the prevalence of HIV-1-associated neurocognitive disorders (HAND) has been on the rise in the post-HAART era. In view of these developments, we investigated whether a HAART drug combination of 3'-Azido-2', 3'-deoxythymidine (AZT) and Indinavir (IDV) can alter the functionality of the blood-brain barrier (BBB) endothelial cells, thereby exacerbating the condition. Viability of hCMEC/D3 cells (in vitro model of BBB) that were exposed to the drugs was significantly reduced after a 72 hr treatment, in a dose-dependent manner. Reactive oxygen species (ROS) were highly …

Robust Frequency-Domain Turbo Equalization For Multiple-Input Multiple-Output (Mimo) Wireless Communications, Jian Zhang

Doctoral Dissertations

"This dissertation investigates single carrier frequency-domain equalization (SC-FDE) with multiple-input multiple-output (MIMO) channels for radio frequency (RF) and underwater acoustic (UWA) wireless communications. It consists of five papers, selected from a total of 13 publications. Each paper focuses on a specific technical challenge of the SC-FDE MIMO system. The first paper proposes an improved frequency-domain channel estimation method based on interpolation to track fast time-varying fading channels using a small amount of training symbols in a large data block. The second paper addresses the carrier frequency offset (CFO) problem using a new group-wise phase estimation and compensation algorithm to combat …

Principals' Leadership Styles And Their Impact On School Climate: Assistant Principals' Perceptions, Bruce R. Mccolumn

College of Graduate Studies: Theses & Dissertations

The primary focus of this study is to explore the perceptions of assistant principals as to how their principals' leadership styles impact school climate. A school's climate plays a vital role in student achievement and principals are the most important factor in setting a setting a school's climate. Therefore, principals' leadership behaviors warrant investigating. This qualitative study identified principal leadership styles through the perceptions of their assistant principals. Interactive interviews were conducted with selected assistant principals in the XYZ School System. Their responses were analyzed, themed and coded to draw a connection between principal leadership style and school climate. These …

Between Return And Resettlement: The Formation Of Iraqi Refugee "Communities" In Cairo And Amman, Emilie K. B. Minnick

Theses and Dissertations

The purpose of this thesis is to investigate whether or not there is community formation among Iraqi refugees living in Amman, Jordan and Cairo, Egypt. These two countries were chosen as case studies because they offer an opportunity to analyze how different host country conditions in the Global South have an impact on the process of community formation. While Egypt is a signatory to the 1951 Refugee Convention and Jordan is not, access to rights in both countries is similarly restrictive. Furthermore, whereas there has been a long history of forced migration from Iraq to Jordan and Iraqi social networks …

Xenophobia: The Consequences Of Being A Zimbabwean In South Africa, Philip Edward Culbertson

Theses and Dissertations

This paper seeks to explain and describe the xenophobia and xenophobic attacks of Zimbabwean refugees and migrants in South Africa. The political and social instability in Zimbabwe has led to mass exodus of Zimbabweans in search of stability and a means to survive. Many of these Zimbabweans have sought opportunity and refuge in South Africa only to be met with hurdles that metastasized into xenophobia. Research was done on the target population of Zimbabweans in Central Methodist Church in Johannesburg, along with interviews conducted through Medicines Sans Frontiers, and active players in the civil society in Cape Town.

Free Speech At What Cost?: Snyder V. Phelps And Speech-Based Tort Liability, Jeffrey Shulman

Georgetown Law Faculty Publications and Other Works

It is always a hard case when fundamental interests collide, but the Fourth Circuit’s decision in Snyder v. Phelps, 580 F.3d 206 (4th Cir. 2009), cert. granted, 130 S. Ct. 1737 (2010), tilts doctrine too far in the direction of free speech, upsetting the Supreme Court’s careful weighing of interests that takes into account both the need for robust political debate and the need to protect private individuals from personal abuse. Where speech is directed at a private individual, especially one unwilling to hear but unable to escape the speaker’s message, the elements of the emotional distress claim more than …

I Put You There: User-Generated Content And Anticircumvention, Rebecca Tushnet

Georgetown Law Faculty Publications and Other Works

This Article discusses recent rulemaking proceedings before the Copyright Office concerning the anticircumvention provisions of the Digital Millennium Copyright Act (DMCA). During these proceedings, non-institutionally affiliated artists organized to assert their interests in making fair use of existing works, adding new voices to the debate. A proposed exemption for noncommercial remix video is justified to address the in terrorem effect of anticircumvention law on fair use. Without an exemption, fair users are subjected to a digital literacy test combined with a digital poll tax, and this regime suppresses fair use. The experience of artists (vidders) confronting the law illustrates both …

Stories Told And Untold: Confidentiality Laws And The Master Narrative Of Child Welfare, Matthew I. Fraidin

Georgetown Law Faculty Publications and Other Works

In most states, child welfare hearings and records are sealed or confidential. This means that by law, court hearings and records may not be observed. The same laws and court rules also preclude those who are authorized to enter and watch from discussing anything learned or observed in a closed courtroom or from a sealed court record with anyone not involved in the case. It is the restriction on speech—on telling stories about child welfare—with which this Article is concerned.

The master narrative of child welfare depicts foster care as a haven for child-victims savagely brutalized by “deviant,” “monstrous” parents. …

Systemic Regulation Of Global Trade And Finance: A Tale Of Two Systems, R. Michael Gadbaw

Georgetown Law Faculty Publications and Other Works

The recent financial crisis has put enormous strains on the global systems governing international finance and trade. These two important international regulatory systems, created after World War II to promote growth and stability in the global economy, were put to the test in ways unprecedented since the 1930s. This article seeks to analyze and compare their performance as systemic regulators in the course of the crisis and concludes that the trading system performed quite well while the financial system virtually collapsed. This article seeks to account for this difference by looking at the nature of the rules and the institutions …

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.

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) …

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 …

Georgetown Law Faculty Publications and Other Works

To examine how academic law libraries can respond to the call for more practice-oriented legal education, the authors compared trends in collection management decisions regarding secondary sources at academic and law firm libraries along with law firm librarians’ perceptions of law school legal research training of new associates.

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 …

Governing Board Accountability: Competition, Regulation And Accreditation, Judith C. Areen

Georgetown Law Faculty Publications and Other Works

This article examines the three primary ways in which the governing boards of American colleges and universities are held to account: (1) competition; (2) regulation, including state nonprofit corporation laws, tax laws, and licensing laws; and (3) accreditation. It begins by tracing how lay (meaning nonfaculty) governing boards became the dominant form of governance in American higher education. It argues that governing boards provide American institutions of higher education with an exceptional degree of autonomy from state control and that, together with the shared governance approach that gives faculties primary responsibility for academic matters, they have been a vital factor …

Mapping The Issues: Public Health, Law And Ethics, Lawrence O. Gostin

Georgetown Law Faculty Publications and Other Works

The field of public health is typically regarded as a positivistic pursuit and, undoubtedly, our understanding of the etiology and response to disease is heavily influenced by scientific inquiry. Public health policies, however, are shaped not only by science but also by ethical values, legal norms, and political oversight. Public Health Law and Ethics: A Reader (expanded and updated 2nd ed., 2010) probes and seeks to illuminate this complex interplay, through a careful selection of government reports, scholarly articles, and court cases together with discussion and analysis of critical problems at the interface of law, ethics, and public health. The …

Redressing The Unconscionable Health Gap: A Global Plan For Justice, Lawrence O. Gostin

Georgetown Law Faculty Publications and Other Works

Consider two children—one born in sub-Saharan Africa and the other in the United States. The African child is twenty-five times more likely to die in the first five years of life; if she lives to child-bearing age, she is a two hundred times more likely to die in labor; and overall, she will die thirty years earlier than the American child. The international community is deeply resistant to taking bold remedial action—more concerned with their geostrategic interests than the health of the poor. The scale of foreign aid is both insufficient and unsustainable and fails to address the key determinants …

Restoring Health To Health Reform, Lawrence O. Gostin, Peter D. Jacobson

Georgetown Law Faculty Publications and Other Works

In this article, we discuss the public health provisions of the Patient Protection and Affordable Care Act (PPACA--P.L. 111-148). We first set forth a framework to identify the key reforms that are needed for a robust public health system. These include workforce and infrastructure investments. We then assess the PPACA against these criteria. We conclude that although the act would make significant investment in public health (especially in wellness and prevention programs), it does little to improve the existing structural deficiencies that the public health system must overcome if it is to be effective in improving the population’s health.

The O’Neill Institute For National And Global Health Law: Discovering Innovative Solutions For The Most Pressing Health Problems Facing The Nation And The World, Lawrence O. Gostin, Oscar A. Cabrera, Susan C. Kim

Georgetown Law Faculty Publications and Other Works

The connection between health and an individual’s ability to function in society, as well as the importance of health to a society’s economic, political, and social wellbeing necessitates finding innovative solutions to the world’s most pressing health problems. The O’Neill Institute for National and Global Health Law at Georgetown University seeks to demonstrate the role that academia can play in addressing complex national and global health problems in a comprehensive, evidence-based, intellectually-rigorous, and nonpartisan manner. The O’Neill Institute currently has three research programs: global health law, national health law, and the center for disease prevention and outcomes. Projects within these …

Health Care Reform In Transition: Incremental Insurance Reform Without An Individual Mandate, Lawrence O. Gostin, Elenora E. Connors

Georgetown Law Faculty Publications and Other Works

A major access problem exists in the private insurance market for individuals with preexisting conditions, who are either denied coverage or charged exorbitant premiums. In effect, individuals are denied coverage for exactly what they need, which jeopardizes their health and the financial security of their family. Before health reform passed, discussions surrounding incremental reform took place, including perhaps the most politically compelling – prohibiting insurers from denying coverage to those with preexisting health conditions. Insurance is based upon the principles of spreading risk of individuals across a population to ensure that everyone can afford medical care when he or she …

Honor Killings And The Construction Of Gender In Arab Societies, Lama Abu-Odeh

Georgetown Law Faculty Publications and Other Works

This Article discusses the regulation and adjudication of honor killings in the Arab world and traces the distributive and disciplinary impact of such regulation/adjudication on Arab men and Arab women's sexuality. In the afterword, the Article outlines the transformative effect of Islamicization of culture in the Arab world in the past twenty years on the practice of honor and killings committed in its name.

To Be Muslim Or "Muslim-Looking" In America: A Comparative Exploration Of Racial And Religious Prejudice In The 21st Century, Sheryll Cashin

Georgetown Law Faculty Publications and Other Works

This Essay begins with a confession. In taking implicit association tests ("IATs") designed to measure my unconscious attitude toward two particular demographic groups, I discovered that I, an African-American, harbored a "slight automatic preference" for Europeans over blacks and for "other people" over "Arab-Muslims." Both of these results were contrary to my professed or conscious assertions of neutrality. Why would a pro-integration scholar who seeks to promote cross-racial understanding and inclusion exhibit such implicit biases? And why is it that a majority of others who take these tests register similar implicit biases? The point of my confession is to underscore …

Sovereignty, Integration And Tax Avoidance In The European Union: Striking The Proper Balance, Lilian V. Faulhaber

Georgetown Law Faculty Publications and Other Works

As the need to raise revenue becomes more pressing and public opposition to tax avoidance increases, the European Court of Justice has made it more difficult for the twenty-seven Member States of the European Union to prevent tax avoidance and shape fiscal policy. This article introduces the new anti-avoidance doctrine of the European Court of Justice and analyzes it from the perspective of taxpayers, Member States and the European Union legal order as a whole. This doctrine is problematic becasue it has created a legislative vacuum in Europe. No European Union institution has the authority to regulate direct taxation without …

Information Integration For Graph Databases, Ee Peng Lim, Aixin Sun, Anwitaman Datta, Chang Kuiyu

Research Collection School Of Computing and Information Systems

With increasing interest in querying and analyzing graph data from multiple sources, algorithms and tools to integrate different graphs become very important. Integration of graphs can take place at the schema and instance levels. While links among graph nodes pose additional challenges to graph information integration, they can also serve as useful features for matching nodes representing real-world entities. This chapter introduces a general framework to perform graph information integration. It then gives an overview of the state-of-the-art research and tools in graph information integration.
