Modeling And Testing Of An R-23/R-134a Mixed Refrigerant System For Low Temperature Refrigeration, Nicholas Hugh, Margaret Mathison, Anthony Bowman

Mechanical Engineering Faculty Research and Publications

Low temperature refrigeration storage equipment in the biotechnology industry typically uses cascade refrigeration to achieve evaporating temperatures of -80 °C (-112 °F) or below. Current systems utilize multiple compressors leading to high energy consumption. Equipment operating costs contribute significantly to the total operating costs of biotechnology companies and therefore motivate the development of more efficient alternatives for low temperature refrigeration. This paper describes a single compressor R-23/R-134a mixed refrigerant cycle that has been designed to extract a load of 0.256 kW (873.5 Btu/hr) from a conditioned space at -80 °C (-112 °F). The designed system compresses a mixture of the …

Revolution Without Reform: A Critique Of Egypt's Election Laws, Sahar F. Aziz

Faculty Scholarship

This Article compares Egypt's election laws before and after the January 25 Revolution to determine whether the changes are sufficient to produce the structural reforms Egyptians demand. This Article concludes that Egyptian elections processes and institutions remain insufficiently transparent, fail to produce results reflecting the diversity within Egyptian society, and fail to offer all Egyptians-especially women and religious minorities-an equal opportunity to actively participate in governance of their country.

The Article critically assesses recent changes in Egypt's electoral regime and considers whether Egypt had a revolution without reform. The thesis is twofold. First, the post-revolution amendments worsen prospects for Egyptian …

Tests For Time Domain Em Solvers For Stability And Towards Passivity, G. Antonini, Albert E. Ruehli, D. Romano, L. (Lijun) Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

Stability issues for time domain integral equation based EM solvers have been a problem for a many years. In this paper, we consider ways to test for stability as well as other criteria towards passivity. The tests are designed to monitor the EM solver while the time domain solution is progressing. Hence, the solution can be terminated and improved with a passivization technique when a violation of the criterion has been detected. Also, the tests help to understand the cause of instabilities and results can be used for passivization. © 2013 IEEE.

A Wide-Band Equivalent Source Reconstruction Method Exploiting The Stoer-Bulirsch Algorithm With The Adaptive Frequency Sampling, P. Li, Y. Li, Lijun Jiang, J. Hu

Electrical and Computer Engineering Faculty Research & Creative Works

Conventional equivalent source reconstruction methods are only operating at a single frequency point each time. However, for wide-band radiators, their computation cost of the source reconstruction increases with the number of frequency points. In this communication, a wide-band equivalent source reconstruction method (WB-SRM) based on the Neville-type Stoer-Bulirsch (SB) algorithm is developed. Since the SB algorithm is a recursive tabular method, it can perform the interpolation over a broadband using a single rational function without any singularity issue. Supported by the adaptive frequency sampling (AFS) scheme, the number of required sampling data is significantly reduced, which leads to much better …

Land Use And Climate Change: Lawyers Negotiating Above Regulation, John R. Nolon

Elisabeth Haub School of Law Faculty Publications

Sea level rise requires a new paradigm for controlling the development of coastal lands that are in harm’s way, calling for adjustments in the law, legal practice, and legal education. This article discusses the historical tendency of the law to adjust to changes in society and the recent emergence of new legal institutions and strategies for mitigating and adapting to climate change, particularly sea level rise. It illustrates how the lack of certainty about the extent and pace of sea level rise collides with the total takings doctrine of the Lucas case to frustrate the application of traditional land use …

Privacy Laws And Privacy Levers: Online Surveillance Versus Economic Development In The People’S Republic Of China, Ann Bartow

Elisabeth Haub School of Law Faculty Publications

This Essay describes and contextualizes the ongoing efforts by the Communist Party of China (CPC) to reconcile two dramatically competing interests: the desire to extensively monitor the communications of its citizenry, and a burning ambition to further develop its banking and financial industries, its high tech innovation capabilities, and its overall share of the “knowledge economy.”

Monitoring and censoring communications, especially via “one-to-many” social networking platforms, is viewed as essential for the prevention of mass anti-Party political activities ranging from peaceful civil disobedience to armed insurrection and for the protection of the reputations of individual Party leaders. Mobile Internet technologies …

From Peer-To-Peer Networks To Cloud Computing: How Technology Is Redefining Child Pornography Laws, Audrey Rogers

Elisabeth Haub School of Law Faculty Publications

This Article traces the history of the child pornography laws and sentencing policy in Part I. Part II explains the technologies that have caused some of the current controversies, and then Part III describes how these technologies have blurred the offenses. Finally, Part IV makes suggestions as to how the law could better reflect technology and comport with a refined harm rationale. Courts, legal scholars, and medical experts have explained the harm includes the sexual abuse captured in the images and the psychological injury the victim endures knowing the images are being viewed. This Article further develops the harm rationale …

A "Blunt Withdrawal"? Bars On Citizen Suits For Toxic Site Cleanup, Margot J. Pollans

Elisabeth Haub School of Law Faculty Publications

Throughout the history of federal statutory environmental law, citizen suits have played a key role in enforcement. Through statutory interpretation, however, courts have narrowed the circumstances under which citizens can sue. This Article explores one such restraint: Courts have severely limited citizen suits under the Resource Conservation and Recovery Act (“RCRA”) by reading very broadly a jurisdiction-stripping provision of RCRA's companion statute, the Comprehensive Environmental Response Compensation and Liability Act (“CERCLA”). This Article argues that courts have read that provision too broadly, not only violating traditional principles for resolving inter-statutory conflict but also undermining the purposes of both statutes by …

Shifting Paradigms Transform Environmental And Land Use Law: The Emergence Of The Law Of Sustainable Development, John R. Nolon

Elisabeth Haub School of Law Faculty Publications

We began these two decades reacting to the market’s interest in developing greenfields and coastal property and end it wondering how to prepare more urbanized places for a growing population of smaller households who seek the amenities of urban living and some protection from the storms ahead. This essay discusses this and nine other fundamental paradigm shifts in environmental and economic conditions that are reshaping the law and changing the way state and local governments control land use and order human settlements.

Teaching Government Information In Information Literacy Credit Classes, Emily Rogers

Georgia Library Quarterly

This paper reviews the teaching of credit-bearing information literacy courses and government information, reports questionnaire responses from librarians who teach these courses, and argues that revising the ways we teach government information in for-credit courses will help students achieve information literacy. A focus on government information as critical thinking and subject access resources, rather than as unique documents collections or formats, can remove barriers for researchers, particularly in classes that allow students an entire term to develop skills. In addition, librarians will increase their comfort levels addressing government information and develop ways to teach students to use these resources within …

Litigation-Fostered Bureaucratic Autonomy: Administrative Law Against Political Control, Daniel E. Walters

Faculty Scholarship

The idea of political control dominates our understanding of both what administrative law does and what it should do. This emphasis on political control, however, downplays the important ways that administrative law facilitates resistance to political control in administrative agencies. In this article, I offer studies of two instances in which agencies harnessed the power of seemingly standard administrative law litigation to resist the imposition of policies by political leadership. I classify these kinds of modes of resistance as instances of “litigation-fostered bureaucratic autonomy” and flesh out the mechanisms that drive the process. Acknowledging the role of such modes of …

Mapping, Modeling, And The Fragmentation Of Environmental Law, Dave Owen

Utah Law Review

In the past forty years, environmental researchers have achieved major advances in electronic mapping and spatially explicit, computerbased simulation modeling. Those advances have turned quantitative spatial analysis—that is, quantitative analysis of data coded to specific geographic locations—into one of the primary modes of environmental research. Researchers now routinely use spatial analysis to explore environmental trends, diagnose problems, discover causal relationships, predict possible futures, and test policy options. At a more fundamental level, these technologies and an associated field of theory are transforming how researchers conceptualize environmental systems.

Advances in spatial analysis have had modest impacts upon the practice of environmental …

Qualified Conservation Restrictions: Recollections Of And Reflections On The Origins Of Section 170(H), Theodore S. Sims

Utah Law Review

It has been over thirty years since Congress added to the Internal Revenue Code section 170(h), which allows a deduction for contributions to charity of “qualified conservation restrictions,” commonly known as “conservation ease- ments”. That provision was adopted over the objections of the Treasury, who had expressed reservations of both a conceptual and practical nature about the legislation, which the Treasury viewed as more than ordinarily vulnerable to abuse. I was invited to participate in this symposium, not because I have any expertise in working with these restrictions—I don’t—but to provide some perspective on what might have motivated the Treasury …

Ppl Montana: The Supreme Court’S Modern Day City Slicker Approach For Determining The Navigability For Title Test, Landon Newell

Utah Law Review

The river thunders in perpetual roar, swelling in floods of music when the storm gods play upon the rocks and fading away in soft and low murmurs when the infinite blue of heaven is unveiled. With the melody of the great tide rising and falling, swelling and vanishing forever, other melodies are heard in the gorges of the lateral canyons, while the waters plunge in the rapids among the rocks or leap in great cataracts.

Environmental Regulatory Nukes, Brigham Daniels

Utah Law Review

Regulatory nukes are regulatory tools that can prove extremely destructive to regulatory targets and have an element of political taboo surrounding their use. This Article discusses how and why Congress proliferates regulatory nukes. It explores the way regulatory nukes shape the contours of environmental law and define important aspects of various environmental enactments, including the Clean Air Act, the Clean Water Act, RCRA, CERCLA, and the Endangered Species Act, among others. The typical narratives we find surrounding environmental regulatory nukes, that either focus on regulatory Armageddon or dust settling on nukes in their silos, only tell part of the story. …

Interstate Groundwater Law In The Snake Valley: Equitable Apportionment And A New Model For Transboundary Aquifer Management, Noah D. Hall, Benjamin L. Cavataro

Utah Law Review

This Article examines how the equitable apportionment doctrine can be applied to an interstate groundwater dispute, using the Snake Valley Aquifer shared by Nevada and Utah as a case study. Equitable apportionment is a viable doctrine for resolving interstate groundwater disputes, but it is not ideal. Instead, interstate compacts provide a constitutional mechanism for cooperation by which states may protect and utilize a shared natural resource. There are over twenty interstate compacts currently in effect, covering major interstate waters such as the Colorado River and the Great Lakes. Some of these compacts address connected groundwater, but none to date are …

Online Learning In A Chemical Perceptron, Peter Banda, Christof Teuscher, Matthew R. Lakin

Computer Science Faculty Publications and Presentations

Autonomous learning implemented purely by means of a synthetic chemical system has not been previously realized. Learning promotes reusability and minimizes the system design to simple input-output specification. In this article we introduce a chemical perceptron, the first full-featured implementation of a perceptron in an artificial (simulated) chemistry. A perceptron is the simplest system capable of learning, inspired by the functioning of a biological neuron. Our artificial chemistry is deterministic and discrete-time, and follows Michaelis-Menten kinetics. We present two models, the weight-loop perceptron and the weight-race perceptron, which represent two possible strategies for a chemical implementation of linear integration and …

First Observations Of So2 From The Satellite Suomi Npp Omps: Widespread Air Pollution Events Over China, Kay Yang, Russell Dickerson, Simon Carn, Cui Ge, Jun Wang

Department of Earth and Atmospheric Sciences: Faculty Publications

Severe smog episodes over China in January 2013 received worldwide attention. This air pollution was distinguished by heavy loadings of fine particulate matter and SO₂. To characterize these episodes, we employed the Ozone Mapping and Profiler Suite, Nadir Mapper (OMPS NM), an ultraviolet (UV) spectrometer flying on the Suomi National Polar-orbiting Partnership (SNPP) spacecraft since October 2011. We developed an advanced algorithm to quantify SO₂ in the lower troposphere and achieved highquality retrievals from OMPS NM, which are characterized by high precision, ~0.2 Dobson Units (DU; 1 DU = 2.69x1016 molecules/cm2) for instantaneous field of view SO …

A Hermeneutic Phenomenological Study Of Non-Completers In Online Doctor Of Education Programs, Bernadette Wyman

Doctoral Dissertations and Projects

The chance of an individual completing a traditional doctorate program is 50% (Bowen & Rudenstine, 1992; Council of Graduate Schools Ph.D. Completion Project, 2008; Ivankova & Stick, 2007). Student attrition in online programs is 10% to 20% greater than that of traditional, residential programs (Allen & Seaman, 2010; Carr, 2000; Diaz, 2000; DiRamio & Wolverton, 2006; Parker, 1999; Rovai, 2002). While doctoral attrition rates have been examined for decades, little research focuses on the phenomenon of attrition with doctoral candidates who enrolled in online graduate programs (Perry, Boman, Care, Edwards & Park, 2008). The phenomenon of attrition is multifaceted and …

Doctoral Dissertations and Projects

According to a Barna Research Group study titled "Third Millennium Teens" 60% of young people will leave the church permanently or for an extended period. Decreasing the number of urban youth ages 14-18 from defecting from the church and to increase retention of church dropouts using Twenty-First Century transformational strategies is the goal of this project. Having served as a youth pastor the writer will analyze key strategies that will benefit high school ministry by raising the bar on expectations and by building future leaders in the church.

This project will include an anonymous survey of 125 participants aged 18-24 …

Exploring Factors That Contribute To Academic Persistence For Undergraduate Hispanic Nontraditional Students At Hispanic Serving Institutions In The Southeast, Floralba Arbelo Marrero

Doctoral Dissertations and Projects

This study examined the academic persistence of 10 undergraduate Hispanic nontraditional students enrolled at a public and a private not for profit Hispanic Serving Institution in the southeastern region of the United States, each in their last year of a bachelor degree program. Using a phenomenological research design and an ecological and sociocultural framework the findings indicated that family context, personal aspirations, campus environment within Hispanic Serving Institutions, life challenges, and English language learning each play a vital role in the persistence behaviors of this population. These factors interact at the student and institutional levels to provide students with internal …

Extending Positive Identification From Persons To Places: Terrorism, Armed Conflict, And The Identification Of Military Objectives, Laurie R. Blank

Utah Law Review

In January 2013, French forces combating rebel forces in Mali attacked "Islamic targets" in northern Mali and French fighter planes "hit rebel targets in the northern cities of Gao and Kidal" Turkish forces frequently attack "rebel positions," fighting the Kurdistan Workers Party (PKK) in Iraq's Kurdistan region, and the Sri Lankan Army targeted "terroris stronghold[s]" during the conflict with the Tamil Tigers. The Israel Defense Forces contend with "rocket villages" in Hezbollah-dominated areas in southern Lebanon and with the complexities of a periodically intensifying conflict with a terroris entity governing the Gaza Strip. In Afghanistan, U.S. and multinational forces seek …

Modules And Dialects As Objects In Grace, Michael Homer, James Noble, Kim B. Bruce, Andrew P. Black

Computer Science Faculty Publications and Presentations

Grace is a gradually typed, object-oriented language for use in education; consonant with that use, we have tried to keep Grace as simple and straightforward as possible. Grace needs a module system for several reasons: to teach students about modular program design, to organise large programs, especially its self-hosted implementation, to provide access to resources defined in other languages, and to support different “dialects”—language subsets, or domain specific languages, for particular parts of the curriculum. Grace already has several organising constructs; this paper describes how Grace uses two of them, objects and lexical scope, to provide modules and dialects.

The Problem Of Semantics In The Metadata Mess, Veronika Margaret Megler, David Maier
