Neutron And Nuclear Inelastic Scattering Study Of The Einstein Oscillators In Ba-, Sr-, And Eu-Filled Germanium Clathrates, Raphaël P. Hermann, Werner Schweika, Olaf Leupold, Rudolf Rüffer, George S. Nolas, Fernande Grandjean, Gary J. Long

Chemistry Faculty Research & Creative Works

Inelastic neutron scattering measurements on Ba₈Ga₁₆Ge₃₀ and Sr₈Ga₁₆Ge₃₀ indicate the presence of soft local modes with Einstein oscillator energies of 4.9±0.1 and 4.4±0.1meV, modes which are associated with the lowest “rattling” mode of the Ba(B) and Sr(B) guests, respectively. Nuclear inelastic scattering measurements on Eu₈Ga₁₆Ge₃₀ yield Einstein oscillator energies of between 3.0±0.3 and 7.5±1.2meV for the different modes of the Eu guests. Further, the resonant character of the measurements on Eu₈Ga₁₆Ge₃₀ reveals, without question, that neither of the Eu guests …

Query Processing In Spatial Databases Containing Obstacles, Jun Zhang, Dimitris Papadias, Kyriakos Mouratidis, Manli Zhu

Research Collection School Of Computing and Information Systems

Despite the existence of obstacles in many database applications, traditional spatial query processing assumes that points in space are directly reachable and utilizes the Euclidean distance metric. In this paper, we study spatial queries in the presence of obstacles, where the obstructed distance between two points is defined as the length of the shortest path that connects them without crossing any obstacles. We propose efficient algorithms for the most important query types, namely, range search, nearest neighbours, e-distance joins, closest pairs and distance semi-joins, assuming that both data objects and obstacles are indexed by R-trees. The effectiveness of the proposed …

Solids Flow Mapping In A High Pressure Slurry Bubble Column, Novica Rados, Ashfaq Shaikh, Muthanna H. Al-Dahhan

Chemical and Biochemical Engineering Faculty Research & Creative Works

Successful Design and Scale-Up of Slurry Bubble Column Reactors (SBCRs) Require Proper Understanding of How Operating Conditions Affect their Flow Behavior. Presently, there is Little Information on the Flow Dynamics of Solids (E.g., Distribution of Velocities and Turbulent Parameters) in Slurry Systems that Are Operated at Industrially Relevant Conditions of High Pressure, High Superficial Gas Velocities, and High Solids Loading. Computer Automated Radio Particle Tracking (CARPT) is Widely Recognized as One of a Few Techniques that Can Be Reliably Used Even in Highly Turbulent and Opaque Slurry Flows. This Work Utilizes an Improved CARPT Technique to Investigate the Effect of …

Compact Autonomous Completely Explosive Pulsed Power System Based On Transverse Shock Wave Demagnetization Of Nd₂Fe₁₄B And Magnetic Flux Compression, Sergey I. Shkuratov, Evgueni F. Talantsev, Jason Baird, Allen H. Stults, Larry L. Altgilbers

Mining Engineering Faculty Research & Creative Works

The design and performance of a compact autonomous completely explosive pulsed power system based on two physical effects, the transverse shock wave demagnetization of Nd2Fe14B high-energy hard ferromagnets and magnetic flux compression, are presented. A transverse shock wave ferromagnetic generator (FMG) served as a seed source, and a compact helical magnetic flux compression generator (FCG) was used as a pulsed power amplifier. Results of a theoretical and experimental study demonstrated reliable operation of the proposed FMG-FCG system. The methodology for analytical calculation of seed current amplitude is developed.

China's Changing Economic Structures And Its Implications For Regional Patterns Of Trade Production And Integration, Kim Song Tan, Hoe Ee Khor

Research Collection School Of Economics

There is tremendous momentum for economic and financial integration in East Asia today. Partly inspired by the formation of the European Union and partly as a response to the 1997/98 Asia financial crisis, many East Asian countries are showing greater commitment to regional economic cooperation. A number of bilateral free trade agreements (FTAs) have either been concluded or are being negotiated.1 At a less formal level, the ASEAN+3 grouping has brought the whole region together in regular consultations over trade, investment, as well as monetary and exchange rate policy matters.

Mining Ontological Knowledge From Domain-Specific Text Documents, Xing Jiang, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

Traditional text mining systems employ shallow parsing techniques and focus on concept extraction and taxonomic relation extraction. This paper presents a novel system called CRCTOL for mining rich semantic knowledge in the form of ontology from domain-specific text documents. By using a full text parsing technique and incorporating both statistical and lexico-syntactic methods, the knowledge extracted by our system is more concise and contains a richer semantics compared with alternative systems. We conduct a case study wherein CRCTOL extracts ontological knowledge, specifically key concepts and semantic relations, from a terrorism domain text collection. Quantitative evaluation, by comparing with a state-of-the-art …

Accurately Extracting Coherent Relevant Passages Using Hidden Markov Models, Jing Jiang, Chengxiang Zhai

In this paper, we present a principled method for accurately extracting coherent relevant passages of variable lengths using HMMs. We show that with appropriate parameter estimation, the HMM method outperforms a number of strong baseline methods on two data sets.

A Threshold-Based Algorithm For Continuous Monitoring Of K Nearest Neighbors, Kyriakos Mouratidis, Dimitris Papadias, Spiridon Bakiras, Yufei Tao

Research Collection School Of Computing and Information Systems

Assume a set of moving objects and a central server that monitors their positions over time, while processing continuous nearest neighbor queries from geographically distributed clients. In order to always report up-to-date results, the server could constantly obtain the most recent position of all objects. However, this naïve solution requires the transmission of a large number of rapid data streams corresponding to location updates. Intuitively, current information is necessary only for objects that may influence some query result (i.e., they may be included in the nearest neighbor set of some client). Motivated by this observation, we present a threshold-based algorithm …

On Security Notions Of Steganographic Systems, Kisik Chang, Robert H. Deng, Feng Bao, Sangjin Lee, Hyungjun Kim

Research Collection School Of Computing and Information Systems

We define the notion of pseudoprocessingness to formulate chosen-input-attack, chosen-stego-attack, and key-recovery. We then construct a efficient, provable secure steganographic algorithm against chosen-input-attack and key-recovery. So far as we know, this is the first paper dealing with those security notions.

Racial Integration And Community Revitalization: Applying The Fair Housing Act To The Low Income Housing Tax Credit, Myron Orfield

Vanderbilt Law Review

A growing national debate about the future of race, housing, and urban policy in the United States is reflected in the recent controversy over the administration of the Low-Income Housing Tax Credit ("LIHTC") program, the largest federal program that supports building low-income housing. Administered by the Treasury Department, the program allows investors in residential rental property to claim tax credits for the development or rehabilitation of property to be rented to low-income tenants. The program is implemented mainly through state agencies which distribute the credit to developers on a competitive basis. Part of the LIHTC statute, which passed without debate …

Endangered Species--Examining South Africa's National Rape Crisis And Its Legislative Attempt To Protect Its Most Vulnerable Citizens, Ashley J. Moore

Vanderbilt Journal of Transnational Law

With the demise of apartheid, South Africans eagerly anticipated the freedom from bondage that liberation brings. More than ten years later, however, remnants of the inhumane system still remain throughout South Africa, with the epidemic rape crisis that currently grips the African nation providing dramatic evidence of the continued hold of apartheid. Scores of South Africa's women and young children must contend with the pervasive sexual violence that permeates the country. These would-be victims live in constant fear of physical attack, while advocates await the South African government's response to this national crisis. Unfortunately, legislation that would dramatically change South …

A Day In The Life Of A Casino Host, Chu-Huan Liu

UNLV Theses, Dissertations, Professional Papers, and Capstones

Casinos usually hire junket representatives and casino hosts to act as a liaison between casino marketing departments and proven high-end guests. Junket representatives are usually independent agents who bring players into a particular casino; in return, they are compensated with commission by that casino. If these players do not spend enough time and money in playing, the casino simply loses interest in that representative. Casino hosts are in-house marketing employees who are fully responsible for retaining the existing good patrons and to bring in potential new guests (Makens & Bowen, 1994).

Deterrence Versus Brutalization: Capital Punishment's Differing Impacts Among States, Joanna M. Shepherd

Michigan Law Review

Policymakers' false beliefs about capital punishment's universal deterrent effect may have caused many people to die needlessly. If deterrence is capital punishment's purpose then, in the majority of states where executions do not deter crime, executions kill convicts uselessly. Moreover, in the many states where the brutalization effect outweighs the deterrent effect, executions not only kill convicts needlessly but also induce the additional murders of many innocent people. After Part II discusses capital punishment's recent history in the United States, Part III reviews the conflict in recent studies on capital punishment and deterrence. Part IV explores differences in states' applications …

A Compliant Contact-Aided Revolute Joint, Jessie R. Cannon, Larry L. Howell

Faculty Publications

This paper presents the compliant contact-aided revolute (CCAR) joint, a planar mechanism capable of performing the functions of a bearing and a spring. The pseudo-rigid-body model is used to predict the behavior of the CCAR joint, and this model is validated through the use of finite element analysis and prototype testing. The CCAR joint is shown to have high maximum rotation and lateral stiffness. A case study is presented, and manufacturing considerations are discussed for the macro, meso, and micro scales.

Social Utility Functions-Part I: Theory, Wynn C. Stirling

Faculty Publications

The dominant approaches to utility-based multiagent decision theory rely on the premise of individual rationality-the doctrine that each individual is committed to achieving the best outcome for itself, regardless of the effect doing so has on others. This fundamentally asocial concept is the basis of conventional von Neumann-Morgenstern (vN-M) utilities but is inadequate to characterize truly cooperative artificial systems. Social utility functions differ from conventional vN-M utilities in that they are functions of multiple decision-maker preferences, rather than actions, and thus permit individuals to expand their spheres of interest beyond the self. A logical basis for coherent reasoning in multiagent …

Social Utility Functions-Part Ii: Applications, Wynn C. Stirling, Richard L. Frost

Faculty Publications

Social utilities account for agent preferences and, thus, can characterize complex interrelationships, such as cooperation, compromise, negotiation, and altruism, that can exist between agents. Satisficing game theory, which is based on social utilities, offers a framework within which to design sophisticated multiagent systems. Key features of this approach are: a) an N-agent system may be represented by a 2N-dimensional Bayesian network, called a praxeic network; b) the theory accommodates a notion of situational altruism (a willingness to defer to others in a controlled way if so doing would actually benefit others under the condition that others wish to take advantage …

Size Matters (Or Should) In Copyright Law, Justin Hughes

Articles

American copyright law has a widely recognized prohibition against the copyrighting of titles, short phrases, and single words. Despite this bar, effective advocacy has often pushed courts into recognizing independent copyright protection for smaller and smaller pieces of expression, particularly in recent cases involving valuation and taxonomy systems. Copyright case law is rife with dicta suggesting protection of short phrases and single words.

This instability in copyright law is rooted in the fiction that we deny copyright protection to short phrases and single words because they lack originality. In fact, there are many short phrases that cross copyright's low threshold …

Created' Enclaves For Enterprise: An Empirical Study Of Singapore's Industrial Parks In Indonesia, Vietnam And China, Caroline Yeoh, Siang Yeung Wong

Research Collection Lee Kong Chian School Of Business

The dynamics of globalization have prompted governments to re-examine accustomed policies, and search for alternative strategies, in order to re-position their economies for the future. This paper explores the spatial context of state involvement in the new economics of competition, with the focus on Singapore's much publicized, and controversial, orchestration of its state enterprise network to encapsulate economic space for Singapore-based firms to expand into the Asian region. This strategic initiative is promulgated on the exportability of Singapore's æstate credibilityÆ, systemic and operational efficiencies, and technological competencies, to locations where these attributes are less certain. A logit model is applied …
