The Role Of Thallium As A Hydrogen Entry Promoter On Cathodically Polarized Hy-130 Steel, G. Zheng, Branko N. Popov, Ralph E. White Jan 1994

The Role Of Thallium As A Hydrogen Entry Promoter On Cathodically Polarized Hy-130 Steel, G. Zheng, Branko N. Popov, Ralph E. White

Faculty Publications

Hydrogen permeation experiments were carried out to investigate the effect of thallium on hydrogen entry into HY-130steel. These experiments show that the presence of thallium ions in an electrolyte drastically increase the hydrogen entry rate. The hydrogen entry efficiency and hydrogen surface coverage were increased by a factor of 10 and 6, respectively. In order to fit the permeation experimental data, the Iyer-Pickering-Zamanzadeh (I-P-Z) hydrogen permeation model was modified by including a mass-transfer term in the discharging equation. The relationship between hydrogen permeation and the hydrogen evolution reaction were investigated and new relationships were obtained.

The Second Amendment And The Personal Right To Arms, William W. Van Alstyne Jan 1994

The Second Amendment And The Personal Right To Arms, William W. Van Alstyne

Faculty Publications

For many years, the Second Amendment was politely ignored, or summarily dismissed, by America's legal academy. In recent years, however, more and more law professors have begun taking the Second Amendment seriously. Professor William Van Alstyne, one of the nation's most respected Constitutional law professors, and the author of a leading Constitutional law casebook; offers his contribution in this essay. Van Alstyne suggests that the Second Amendment means exactly what it says: that individual citizens have a right, not merely a privilege, to own and carry firearms. He also commends the National Rifle Association for its constructive role as a …

The Bespeaks Caution Doctrine: Revisiting The Application Of Federal Securities Law To Opinions And Estimates, Royce De R. Barondes Jan 1994

The Bespeaks Caution Doctrine: Revisiting The Application Of Federal Securities Law To Opinions And Estimates, Royce De R. Barondes

Faculty Publications

Disclosure of estimates and opinions, which are often referred to as ‘soft information,‘ has presented a number of difficult issues to courts, the Securities and Exchange Commission (SEC) and companies issuing offering materials or required to file periodic reports with the SEC. Although this type of information often consists of projections, historical financial statements also include this type of information to varying degrees. For example, a bank's statement of financial position requires specification of loan loss reserves and is therefore dependent on an assessment of future events (the timing and extent of repayment). Similarly, determination of the timing of a …

Microscopic Simulation Of Dilute Gases With Adjustable Transport Coefficients, Alejandro Garcia, F. Baras, M. Malek Mansour Jan 1994

Microscopic Simulation Of Dilute Gases With Adjustable Transport Coefficients, Alejandro Garcia, F. Baras, M. Malek Mansour

Faculty Publications

The Bird algorithm is a computationally efficient method for simulating dilute gas flows. However, due to the relatively large transport coefficients at low densities, high Rayleigh or Reynolds numbers are difficult to achieve by this technique. We present a modified version of the Bird algorithm in which the relaxation processes are enhanced and the transport coefficients reduced, while preserving the correct equilibrium and nonequilibrium fluid properties. The present algorithm is found to be two to three orders of magnitude faster than molecular dynamics for simulating complex hydrodynamical flows.

A Report On The Assessment Procedures Used In The Evaluation Of Student Teaching At The Middle School Level, Joane W. Mckay Jan 1994

A Report On The Assessment Procedures Used In The Evaluation Of Student Teaching At The Middle School Level, Joane W. Mckay

Faculty Publications

This conference paper on assessment of the qualities of student teachers in middle schools discusses the concepts of authentic assessment; continuous evaluation; the roles of the cooperating teacher and the university coordinator; and assessment procedures used at the University of Northern Iowa. Eleven categories are presented for use in determining; at mid-term of the student teaching experience; whether a student teacher is meeting the requirements to become an effective teacher. These are: knowledge of content and skills areas; knowledge of learners/learning process; use of instructional planning strategies; use of instructional strategies/teaching styles; use of management and discipline strategies; use of …

Oscillator Strengths For Fe Ii Transitions At 224.918 And 226.008 Nanometers, Scott D. Bergeson, K. L. Mullman, J. E. Lawler Jan 1994

Oscillator Strengths For Fe Ii Transitions At 224.918 And 226.008 Nanometers, Scott D. Bergeson, K. L. Mullman, J. E. Lawler

Faculty Publications

We report accurate experimental absorption oscillator strengths (f-values) for transitions out of the ground level of Fe II to the z4Do7/2 and z4Do9/2 levels at 224.918 and 226.008 nm (air wavelengths) to be 0.00182(14) and 0.00244(19), respectively. The number in parenthesis is the uncertainty in the last digits. These two lines are important for studying Fe abundances and grain depletions in the interstellar medium. These f-values are determined by combining emission branching fractions with radiative lifetimes. Branching fractions are measured using classical spectroradiometry on an optically thin source. Radiative lifetimes are from …

Employment-Based Health Insurance And Job Mobility: Is There Evidence Of Job-Lock?, Brigitte C. Madrian Jan 1994

Employment-Based Health Insurance And Job Mobility: Is There Evidence Of Job-Lock?, Brigitte C. Madrian

Faculty Publications

This paper assesses the impact of employer-provided health insurance on job mobility by exploring the extent to which workers are "locked' into their jobs because preexisting conditions exclusions make it expensive for individuals with medical problems to relinquish their current health insurance. I estimate the degree of job-lock by comparing the difference in the turnover rates of those with high and low medical expenses for those with and without employer-provided health insurance. Using data from the 1987 National Medical Expenditure Survey, I estimate that job-lock reduces the voluntary turnover rate of those with employer-provided health insurance by 25 percent, from …

Plate Motions In The North Andean Region, Jeffrey T. Freymueller, James N. Kellogg, Victor Vega Dec 1993

Plate Motions In The North Andean Region, Jeffrey T. Freymueller, James N. Kellogg, Victor Vega

Faculty Publications

Repeated geodetic measurements with the Global Positioning System (GPS) provide direct measurements of displacements due to plate motions and active crustal deformation in Central America and northern South America, an area of complex interaction of the Nazca, Cocos, Caribbean and South American plates. The displacement rates for the period 1988-1991, obtained from the results of the first three Central And South America (CASA) GPS campaigns, are in general agreement with the predictions of the NUVEL-1 plate motion model, but there are differences in detail between the observations and the model. The Nazca-North Andes convergence rate vector measured by GPS is …

Neutron Reflection Interferometry: Physical Principles Of Surface Analysis With Phase Information, Vladimir Gudkov, G. I. Opat, A. G. Klein Dec 1993

Neutron Reflection Interferometry: Physical Principles Of Surface Analysis With Phase Information, Vladimir Gudkov, G. I. Opat, A. G. Klein

Faculty Publications

It is shown that the analysis of surface layers by neutron reflection interferometry is considerably enhanced by performing the reflectometry with phase information. We discuss two methods of providing such information. One method involves physically adding an extra reference layer, whose amplitude and phase are known theoretically. The other uses the Lloyd's mirror configuration, in which a directly propagating ray that interferes with the reflected ray supplies the phase information. The methods have much in common with holography.

The Importance Of Using Multiple Styles Of Generalization, Tony R. Martinez, D. Randall Wilson Nov 1993

The Importance Of Using Multiple Styles Of Generalization, Tony R. Martinez, D. Randall Wilson

Faculty Publications

There are many ways for a learning system to generalize from training set data. There is likely no one style of generalization which will solve all problems better than any other style, for different styles will work better on some applications than others. This paper presents several styles of generalization and uses them to suggest that a collection of such styles can provide more accurate generalization than any one style by itself. Empirical results of generalizing on several real-world applications are given, and comparisons are made on the generalization accuracy of each style of generalization. The empirical results support the …

Towards A General Distributed Platform For Learning And Generalization, Brent W. Hughes, Tony R. Martinez Nov 1993

Towards A General Distributed Platform For Learning And Generalization, Brent W. Hughes, Tony R. Martinez

Faculty Publications

Different learning models employ different styles of generalization on novel inputs. This paper proposes the need for multiple styles of generalization to support a broad application base. The Priority ASOCS model (Priority Adaptive Self-organizing Concurrent System) is overviewed and presented as a potential platform which can support multiple generalization styles. PASOCS is an adaptive network composed of many simple computing elements operating asynchronously and in parallel. The PASOCS can operate in either a data processing mode or a learning mode. During data processing mode, the system acts as a parallel hardware circuit. During leaming mode, the PASOCS incorporates rules, with …

The Effect Of Verbal Elaborations On Memory In Young And Older Adults, Katie E. Cherry, Denise C. Park, David A. Frieske, Renee L. Rowley Nov 1993

The Effect Of Verbal Elaborations On Memory In Young And Older Adults, Katie E. Cherry, Denise C. Park, David A. Frieske, Renee L. Rowley

Faculty Publications

The Stein paradigm was used to examine the circumstances under which verbal elaborations enhance memory in young and older adults. Subjects studied target adjectives that were embedded in one of three sentence contexts that varied in elaboration of the subject-adjective relationship: (1) nonelaborated base sentences; (2) base sentences with semantically consistent, but arbitrary verbal, elaborations; and (3) base sentences with explanatory verbal elaborations that clarified the significance of the subject-adjective relationship. The presence of the elaborations was varied at encoding and retrieval, and cued recall of the target adjectives was tested with incidental and intentional learning procedures. In Experiments 1A …

In deep inelastic, neutral current scattering of electrons and protons at s=296 GeV, we observe in the ZEUS detector events with a large rapidity gap in the hadronic final state. They occur in the region of small Bjorken x and are observed up to Q2 of 100 GeV2. They account for about 5% of the events with Q2≥10 GeV2. Their general properties are inconsistent with the dominant mechanism of deep inelastic scattering, where color is transferred between the scattered quark and the proton remnant, and suggest that the underlying production mechanism is the diffractive dissociation of the virtual photon. © …

Banning The Cultural Exclusion: Free Trade And Copyrighted Goods, S. I. Strong Oct 1993

Banning The Cultural Exclusion: Free Trade And Copyrighted Goods, S. I. Strong

Faculty Publications

For centuries people have expressed themselves through creative works of art and literature, and since 1557 artists and authors have been able to protect their rights to their creative works through various national copyright laws. National copyright laws basically grant a monopoly in the use of the work to its creator. Copyrighted goods, however, are often easily transported across national boundaries, and thus national copyright laws may provide inadequate copyright protection in the international marketplace. The necessity for international copyright protection has been met to some extent by copyright conventions. International copyright conventions, like national copyright laws, define the scope …

The Role Of The Federal Magistrate Judge In Civil Justice Reform, R. Lawrence Dessem Oct 1993

The Role Of The Federal Magistrate Judge In Civil Justice Reform, R. Lawrence Dessem

Faculty Publications

This Article considers the role of the United States magistrate judge in civil justice reform and, more specifically, the role that the early implementation districts envision for magistrate judges within their own districts. Part I briefly considers the evolution of the office of magistrate judge prior to the enactment of the Judicial Improvements Act of 1990. Part II addresses the treatment of magistrate judges under that legislation. Next, Part III recounts the roles assigned to magistrate judges under the Civil Justice Reform Act in the individual district courts. These varying uses of magistrate judges then will be critiqued in Part …

Proportional Liability: Statistical Evidence And The Probability Paradox, David A. Fischer Oct 1993

Proportional Liability: Statistical Evidence And The Probability Paradox, David A. Fischer

Faculty Publications

Three major policies underlie tort liability: deterrence, compensation, and corrective justice. A primary justification for proportional liability is its alleged superiority in advancing the tort policy of deterrence. This Article demonstrates a significant flaw in this claim by showing that the use of tort liability in multiple cause cases involving statistical evidence in fact serves the policy of deterrence quite poorly.

Of Hotel Revenues, Rents, And Formalism In The Bankruptcy Courts: Implications For Reforming Commercial Real Estate Finance, R. Wilson Freyermuth Oct 1993

Of Hotel Revenues, Rents, And Formalism In The Bankruptcy Courts: Implications For Reforming Commercial Real Estate Finance, R. Wilson Freyermuth

Faculty Publications

This article is intended to continue the dialogue begun by the proposed Restatement and has two distinct goals in this effort. Parts I through III argue that the position of the Restatement drafters is both legally and functionally sound and that bankruptcy courts should embrace and apply the proposed Restatement in administering distressed real estate developments. Part I reviews the reasoning articulated in the hotel bankruptcy cases, demonstrating how courts have applied the provisions of the Bankruptcy Code and state law in a formalistic manner to extinguish the hotel mortgagee's lien upon postpetition room revenues. Part II rejects the analysis …

Driven Diffusion Of Particles, First-Passage Front, And Interface Growth, R. Bidaux, Ras B. Pandey Oct 1993

Driven Diffusion Of Particles, First-Passage Front, And Interface Growth, R. Bidaux, Ras B. Pandey

Faculty Publications

We study a computer-simulation model for driven particles on a discrete lattice where a fraction p of the lattice sites is randomly occupied by frozen impurities (barriers), and an imposed bias governs the particles’ hopping through the lattice. These particles (the carriers) are initially released from a source of wetting fluid from one end of the lattice in order to wet and the dry lattice on their trails. We study the transport of particles, frontier of their trail, and the growth of the interface between the wet and dry regions as a function of the biased field and the number …

Declarative Representations Of Multiagent Systems, Munindar P. Singh, Michael N. Huhns, Larry M. Stevens Oct 1993

Declarative Representations Of Multiagent Systems, Munindar P. Singh, Michael N. Huhns, Larry M. Stevens

Faculty Publications

This paper explores the specification and semantics of multiagent problem-solving systems, focusing on the representations that agents have of each other. It provides a declarative representation for such systems. Several procedural solutions to a well-known test-bed problem are considered, and the requirements they impose on different agents are identified. A study of these requirements yields a representational scheme based on temporal logic for specifying the acting, perceiving, communicating, and reasoning abilities of computational agents. A formal semantics is provided for this scheme. The resulting representation is highly declarative, and useful for describing systems of agents solving problems reactively.
