Commitments Among Agents, Ashok U. Mallya, Michael N. Huhns Jan 2003

Commitments Among Agents, Ashok U. Mallya, Michael N. Huhns

Faculty Publications

Commitments are a powerful representation for modeling multiagent interactions. Previous approaches have considered the semantics of commitments and how to check compliance with them. However, these approaches do not capture some of the subtleties that arise in real-life applications such as e-commerce, in which contracts and institutions have implicit temporal references. In this column, we describe a rich representation for the temporal content of commitments that lets us capture realistic contracts and avoid ambiguities. Consequently, this approach lets us reason about whether, and at what point, a commitment is satisfied or breached, and whether it is or ever becomes unenforceable.

Sibling Recurrence Risk Ratio Analysis Of The Metabolic Syndrome And Its Components Over Time., Wei J. Chen, Pi Hua Liu, Yen Yi Ho, Kuo Liong Chien, Min Tzu Lo, Wei Liang Shih, Yu Chun Yen, Wen Chung Lee

Faculty Publications

The purpose of this study was to estimate both cross-sectional sibling recurrence risk ratio (lambdas) and lifetime lambdas for the metabolic syndrome and its individual components over time among sibships in the prospectively followed-up cohorts provided by the Genetic Analysis Workshop 13. Five measures included in the operational criteria of the metabolic syndrome by the Adult Treatment Panel III were examined. A method for estimating sibling recurrence risk with correction for complete ascertainment was used to estimate the numerator, and the prevalence in the whole cohort was used as the denominator of lambdas. Considerable variability in the lambdas was found …

Enforcement Of Wto Rulings: An Interest Group Analysis, Mark L. Movsesian Jan 2003

Enforcement Of Wto Rulings: An Interest Group Analysis, Mark L. Movsesian

Faculty Publications

The WTO's Dispute Settlement Understanding ("DSU") provides that disputes are to be resolved in adversarial proceedings before impartial panels of experts. These panels have authority to decide whether members' laws conform to WTO requirements; members may appeal rulings to a permanent Appellate Body within the organization, which has the final say on questions of law and legal interpretation. Under the DSU, if a member fails to comply with a final ruling in a dispute, the prevailing party may retaliate by suspending trade concessions that it owes the offending member. This retaliation can continue until the offending member implements the WTO's …

Theoretical Analysis For Obtaining Physical Properties Of Composite Electrodes, Parthasarathy M. Gomadam, John W. Weidner, Thomas A. Zawodzinski, Andrew P. Saab Jan 2003

Theoretical Analysis For Obtaining Physical Properties Of Composite Electrodes, Parthasarathy M. Gomadam, John W. Weidner, Thomas A. Zawodzinski, Andrew P. Saab

Faculty Publications

A theoretical analysis is presented that allows in situ measurements of the physical properties of a composite electrode, namely, the electronic conductivity, the ionic conductivity, the exchange-current density, and the double-layer capacitance. Use is made of the current-voltage responses of the composite electrode to dc and ac polarizations under three different experimental configurations. This analysis allows the physical properties to be obtained even when the various resistances in the composite (e.g., ionic, electronic, and charge-transfer) are of comparable values.

Modeling Heat Conduction In Spiral Geometries, Parthasarathy M. Gomadam, Ralph E. White, John W. Weidner Jan 2003

Modeling Heat Conduction In Spiral Geometries, Parthasarathy M. Gomadam, Ralph E. White, John W. Weidner

Faculty Publications

A two-dimensional (2-D) energy balance (the 2D model) is reduced to a one-dimensioanl (1-D) energy balance (the 1D-radial-spiral model) by a coordinate transformation approach. The 1D-radial-spiral model, even though 1-D, captures both radial and spiral heat conductions over a wide range of design parameters. By comparing the temperature predictions of the 1D-radial-spiral model and the 2D model, parameter ranges were identified where spiral conduction was important and where the 1D-radial-spiral model held. The 1D-radial-spiral model provided a sixtyfold savings in computation time over the 2D model. When coupled to electrochemistry, the 2D model took approximately 20 h to simulate a …

Analysis Of Molten Carbonate Fuel Cell Performance Using A Three-Phase Homogeneous Model, N. Subramanian, B. S. Haran, P. Ganesan, Ralph E. White, Branko N. Popov Jan 2003

Analysis Of Molten Carbonate Fuel Cell Performance Using A Three-Phase Homogeneous Model, N. Subramanian, B. S. Haran, P. Ganesan, Ralph E. White, Branko N. Popov

Faculty Publications

In this study a three-phase homogeneous model was developed to simulate the performance of the molten carbonate fuel cell (MCFC) cathode. The homogeneous model is based on volume averaging of different variables in the three phases over a small volume element. This approach can be used to model porous electrodes as it represents the real system much better than the conventional agglomerate model. Using the homogeneous model the polarization characteristics of the MCFC cathode was studied under different operating conditions.

A Mathematical Model Of Oxide/Carbon Composite Electrode For Supercapacitors, Hansung Kim, Branko N. Popov Jan 2003

A Mathematical Model Of Oxide/Carbon Composite Electrode For Supercapacitors, Hansung Kim, Branko N. Popov

Faculty Publications

A pseudo two-dimensional model is developed for the general application of supercapacitors consisting of an oxide/carbon composite electrode. The model takes into account the diffusion of protons in the oxide particle by employing the method of superposition. RuO2/carbon system is modeled as a specific example. From the simulation data, it is found that the oxide particle size and proton diffusion coefficient have an enormous effect on the performance at high discharge rate due to the limitation of proton transport into RuO2 particles. With increasing carbon ratio, the porosity of electrode increases, which causes the potential drop in …

A Novel Electrodeposition Process For Plating Zn-Ni-Cd Alloys, Hansung Kim, Branko N. Popov, Ken S. Chen Jan 2003

A Novel Electrodeposition Process For Plating Zn-Ni-Cd Alloys, Hansung Kim, Branko N. Popov, Ken S. Chen

Faculty Publications

Zn-Ni-Cd alloy was electrodeposited from an alkaline electrolytic bath under potentiostatic conditions. Bath analyses using a pH concentration diagram reveal that addition of a complexing agent is essential to maintain the bath stability. Introduction of a low concentration of CdSO4 reduces the anomalous nature of the Zn-Ni deposit. Deposits obtained from the electrolytic bath which contains 60 g/L of ZnSO4·7H2O, 40 g/L of NiSO4·6H2O, 1 g/L of CdSO4, and 80 g/L of (NH4)2SO4 in the presence of additives and ammonium hydroxide at pH 9.3 …

Nitroalkane Anomaly: Computational Study With Cluster And Continuum Modeling, H. Yamataka, Salai Cheettu Ammal Jan 2003

Nitroalkane Anomaly: Computational Study With Cluster And Continuum Modeling, H. Yamataka, Salai Cheettu Ammal

Faculty Publications

The origin of anomalous relation between rates and equilibria for the proton-transfer reactions of nitroalkanes, known as nitroalkane anomaly, was investigated by theoretical calculations with a cluster model, in which three water molecules are explicitly considered in the system, as well as the PCM solvent continuum model. For the CH3NO2/CH3CH2NO2 system, B3LYP and MP2 computations reproduced the anomaly, and the imbalance in the charge distribution at the transition state (TS) was observed. In contrast, although the TS imbalance was detected for the substituted phenylnitromethane system, the Brønsted plots did not show any anomaly. The experimentally observed abnormally large Brønsted coefficient …

Mormons And The Media, 1898-2003: A Selected, Annotated, And Indexed Bibliography (With Suggestions For Future Research), Sherry Baker, Daniel Stout

Faculty Publications

Print, electronic, and other forms of communications media have been consistently perceived and characterized by leaders of The Church of Jesus Christ of Latter-day Saints as tools to assist in spreading the gospel message throughout the world. Given this perspective, the Church from its earliest days has used various forms of media as vehicles of communication. It has produced or been affiliated with the production of numerous newspapers and magazines in the United States and in several countries worldwide. In the twentieth century, the Church embraced electronic media technologies promptly. Our goal as mass communications scholars was to compile a …

Searching Large Collections Of Recorded Speech: A Preliminary Study, Jinmook Kim, Douglas W. Oard, Dagobert Soergel Jan 2003

Searching Large Collections Of Recorded Speech: A Preliminary Study, Jinmook Kim, Douglas W. Oard, Dagobert Soergel

Faculty Publications

This paper reports on an exploratory study of the criteria searchers use when judging the relevance of recorded speech from radio programs and the attributes of a recording on which those judgments are based. Five volunteers each performed three searches using two systems (NPR Online and SpeechBot) for three questions and judged the relevance of the results. Data were collected through observation and screen capture, think aloud, and interviews; coded; and analyzed by looking for patterns. Criteria used as a basis for selection were found to be similar to those observed in relevance studies with printed materials, but the attributes …

War: Rhetoric And Norm-Creation In Response To Terror, Tawia Baidoe Ansah Jan 2003

War: Rhetoric And Norm-Creation In Response To Terror, Tawia Baidoe Ansah

Faculty Publications

Everything is very simple in war," said Carl von Clausewitz, "but the simplest thing is difficult." This essay will suggest that the resort to the language of war, as "natural" and "starkly simple" as it is, nevertheless has a profound impact on how the law's intervention is shaped, or how the laws governing the transnational use of force are interpreted to accommodate a "war" on terrorism. I argue that although "war" is absent from the principal international legal instruments by which states are guided (and obligated) in their relations with other states, the concepts suppressed by this elision have an …

Due Process Erosion: The Diminution Of Live Testimony At The Icty, Megan A. Fairlie Jan 2003

Due Process Erosion: The Diminution Of Live Testimony At The Icty, Megan A. Fairlie

Faculty Publications

Shortly after its creation in 1993, the International Criminal Tribunal for the former Yugoslavia (ICTY) adopted an adversarial construct and advocated a preference for the presentation of direct evidence, or live witness testimony, in its criminal trials. In the wake of that decision and under considerable pressure to expedite its proceedings, the ICTY judges responded with efforts to streamline the trial process, amending the Tribunal’s Rules of Procedure and Evidence so as to incrementally increase the admissibility of written evidence. This article tracks the relevant rule changes and questions the merit of the decision to move away from live testimony. …

Spectral Measures And Perceptual Ratings Of Hypokinetic Dysarthria, Christopher Dromey Jan 2003

Spectral Measures And Perceptual Ratings Of Hypokinetic Dysarthria, Christopher Dromey

Faculty Publications

Ten individuals with Parkinson disease (PD) and hypokinetic dysarthria were compared with age-matched neurologically normal (NN) speakers on acoustic measures from speaking and vowel phonation tasks as well as on perceptual ratings of connected speech. Listeners identified differences between the groups when asked to judge the severity of vocal and articulatory impairment during reading. Several conventional acoustic measures failed to differentiate speakers with PD from NN speakers. However, measures of the shape (statistical moments) of the long term average spectrum (LTAS) revealed statistically significant differences between the groups across vowel phonation, reading and monologue tasks. The ease of computation of …

Massive Deliberation, William H. Turkett Jr., John R. Rose, Michael N. Huhns Jan 2003

Massive Deliberation, William H. Turkett Jr., John R. Rose, Michael N. Huhns

Faculty Publications

Agents are proliferating on the Web, making it conceivable that their collective reasoning ability might someday be harnessed for robust decision-making. The hope is that massive deliberation power can soon help solve problems that require knowledge, reasoning, and intelligence. Until recently, working individually or in small groups, agents across the Web could barely communicate and could only reason under conditions of severely bounded rationality. Projects such as Agentcities showed that widespread heterogeneous agents could collaborate on specific predefined tasks and provide diverse agent-based services. When the tasks are dynamic, of long duration, and ill defined, however, success requires planning that …

Parenting Skills And Social-Communicative Competence In Childhood, Craig H. Hart, Lloyd D. Newell, Susanne Frost Olsen

Faculty Publications

The ways that children implement social and communication skills in peer-group interaction provide the foundation for successful later life adjustment (Rubin, Bukowski, & Parker, 1998). Research findings suggest that a host of variables are involved (Hart, Olsen, Robinson, & Mandleco, 1997). These include family processes involving marital and sibling relationships, parenting (e.g., Dunn, 2002; Hart, Nelson, et al., 2000; Stafford & Bayer, 1993), biologically based genetic and temperament factors (e.g., Pike, 2002; Plomin & Rutter, 1998; Sanson, Hemphill, & Smart, 2002), and extrafamilial influences, including the peer group, schools, media, and culture (e.g., Hart, Yang, Nelson, Jin, & Nelson, 1998; …

Motion Planning Using Potential Fields, Randal W. Beard, Timothy W. Mclain Jan 2003

Motion Planning Using Potential Fields, Randal W. Beard, Timothy W. Mclain

Faculty Publications

The objective of these notes is to describe a reactive approach to motion planning for mobile robots. In a reactive approach, trajectories are not planned explicitly. Rather, robot interactions are defined explicitly and the robot motion is said to "emerge." The drawback of reactive methods is that it is sometimes difficult to get the robot to do exactly what you want. The reactive approach that will be described in these notes is called the "virtual fields" method and is commonly used in robotics.

Scripture Note: Doctrine And Covenants 125, Fred E. Woods Jan 2003

Scripture Note: Doctrine And Covenants 125, Fred E. Woods

Faculty Publications

On 19 January 1841, the Lord gave a revelation to Joseph Smith regarding the building of the Nauvoo Temple and issued a call for the faithful Saints to gather to assist in the building of this sacred edifice (see D&C 124: 25-55). With the emphasis on the gathering to Nauvoo and the building of the temple, the Iowa Saints on the eastern banks of the Mississippi were wondering if they should move across the river to Nauvoo. Therefore, in March 1841, the Prophet Joseph Smith posed the question, "What is the will of the Lord concerning the saints in the …

Who Controls The Water? Yahweh Vs. Baal, Fred E. Woods Jan 2003

Who Controls The Water? Yahweh Vs. Baal, Fred E. Woods

Faculty Publications

As the Israelites settled in the land of Canaan, clashes over religious beliefs and practices developed with other inhabitants of the land. Baalism, the belief in the Canaanite god of water and storm, became a threat to the true belief in Yahweh (Jehovah). This paper is an investigation of the implicit polemical usage of water and storm language in the Deuteronomic History (hereafter referred to as DH). The DH consists of the book of Deuteronomy as well as what is referred to in the Hebrew Bible as the Former Prophets (Joshua, Judges, Samuel, and Kings). Many passages in the Deuteronomic …

“Rocky Mountain Entrepreneur: Robert Campbell As A Fur Trade Capitalist.”, Jay H. Buckley

Faculty Publications

Between 1825 and 1835 Robert Campbell emerged as a fur trade entrepreneur. Campbell served as clerk for Ashley-Smith, as brigade leader for Smith, Jackson, and Sublette, and supplier and financier for the Rocky Mountain Fur Company. Campbell quickly became a dominant figure in the American fur trade. In addition to leading fur brigades, Campbell and his partner William Sublette built several trading posts (most notably Fort Laramie), supplied the annual rendezvous, and challenged John Jacob Astor's American Fur Company on the Missouri River. Through it all, Campbell's business acumen helped him pursue economic opportunities that paved the way for future …
