Time-Courses In The Retention Of Food Material In The Bivalves Potamocorbula Amurensis And Macoma Balthica: Significance To The Absorption Of Carbon And Chromium, Alan W. Decho, Samuel N. Luoma Dec 1991

Time-Courses In The Retention Of Food Material In The Bivalves Potamocorbula Amurensis And Macoma Balthica: Significance To The Absorption Of Carbon And Chromium, Alan W. Decho, Samuel N. Luoma

Faculty Publications

Time courses for ingestion, retention and release via feces of microbial food was investigated using 2 bivalves with different feeding strategies, Potamocorbula amurensis, and Macoma balthica. The results showed 2 pathways for the uptake of food material in these clams. The first is represented by an initial label pulse in the feces. The second pathway operates over longer time periods. Inert 51Cr-labeled beads were used to determine time frames for these pathways. The first pathway, involving extracellular digestion and intestinal uptake, is relatively inefficient in the digestion of bacterial cells by P. amurensis but more efficient in …

"Interpretative Aims And Textual-Critical Decisions: Some Historical Constraints In The Discrimination Of Textual Versions", Patrick G. Scott Nov 1991

"Interpretative Aims And Textual-Critical Decisions: Some Historical Constraints In The Discrimination Of Textual Versions", Patrick G. Scott

Faculty Publications

Responds to a recent article by Peter Shillingsburg (in Studies in Bibliography , 1991)on the taxonomy of authorial revision or textual versions, arguing that for critical, biographical and historical study the editor (and interpreter) is constrained in the choice of variant by the purpose for which the text is being used. Examples are drawn from Victorian authors, including Alfred Tennyson, specifically the versions of Maud, and John Henry Newman, specifically successive versions of what became The Idea of the University. Originally presented at a symposium on Shillingsburg's article at the Textual and Bibliographical Studies Section, South Atlantic Modern …

The Effect Of A Tilted Magnetic Field On The Equilibrium Of A Pure Electron Plasma, Grant W. Hart Nov 1991

The Effect Of A Tilted Magnetic Field On The Equilibrium Of A Pure Electron Plasma, Grant W. Hart

Faculty Publications

If the magnetic field in a pure electron plasma containment device is not aligned with the axis of the conducting walls, the electrons in the device will accumulate at the ends of the plasma where the magnetic field lines come closest to the walls and the electrons bound to the field lines can be closest to their image charges. If the plasma is also offset radially from the center (as with an l=1 diocotron mode), then more density will accumulate at one end than the other. As the plasma revolves around the center, the electrons will slosh from one end …

Case-Based Reasoning And Risk Assessment In Audit Judgment, Eric L. Denna, James V. Hansen, Rayman D. Meservy, Larry E. Wood Sep 1991

Case-Based Reasoning And Risk Assessment In Audit Judgment, Eric L. Denna, James V. Hansen, Rayman D. Meservy, Larry E. Wood

Faculty Publications

The purpose of this paper is to describe the results of an effort to utilize Case Based Reasoning (CBR) to model a specific audit judgment task. To date most efforts to develop computational models of audit judgment have used strictly rule-based representation methods. Some researchers have recently adopted more robust structures to model the auditor domain knowledge. Although these recent efforts to extend the representation methods appear to be more accurate descriptions of auditor reasoning and memory, they still lack a comprehensive. theory to guide the development of the model. A commonly encountered phenomenon in audit judgment is for an …

A Self-Organizing Binary Decision Tree For Incrementally Defined Rule-Based Systems, Douglas M. Campbell, Tony R. Martinez Sep 1991

A Self-Organizing Binary Decision Tree For Incrementally Defined Rule-Based Systems, Douglas M. Campbell, Tony R. Martinez

Faculty Publications

This paper presents an adaptive self-organizing concurrent system (ASOCS) model for massively parallel processing of incrementally defined rule systems in such areas as adaptive logic, robotics, logical inference, and dynamic control. An ASOCS is an adaptive network composed of many simple computing elements operating asynchronously and in parallel. This paper focuses on adaptive algorithm 3 (AA3) and details its architecture and learning algorithm. It has advantages over previous ASOCS models in simplicity, implementability, and cost. An ASOCS can operate in either a data processing mode or a learning mode. During the data processing mode, an ASOCS acts as a parallel …

Spaceborne Radar Measurement Of Wind Velocity Over The Ocean-An Overview Of The Nscat Scatterometer System, David G. Long, F. M. Naderi, Michael H. Freilich Jun 1991

Spaceborne Radar Measurement Of Wind Velocity Over The Ocean-An Overview Of The Nscat Scatterometer System, David G. Long, F. M. Naderi, Michael H. Freilich

Faculty Publications

Scatterometry and scatterometer design issues are reviewed. The design of the NASA Scatterometer (NSCAT) to be flown on the Japanese ADEOS mission is presented. Building on Seasat experience, the NSCAT system includes several enhancements, such as three antenna azimuths in each of two swaths, and an onboard digital Doppler processor to allow backscatter measurements to be colocated everywhere within the orbit. These enhancements will greatly increase the quality of the NSCAT wind data. The ground processing of data is discussed, and scatterometers of the next decade are briefly described.

Development And , Application Of Expert Systems In Audit Services, Eric L. Denna, James V. Hansen, Rayman D. Meservy

Faculty Publications

Professional auditing has become much more complex over the past decade. This development has engendered a need for leveraging auditor expertise. In an attempt to meet this need, public accounting firms have been actively involved in supporting the development and application of artificial intelligence methods in audit services, which forms the foundation of their business. Much of the development and application of artificial intelligence in auditing has taken the form of expert systems. This paper examines the current state of the art and provides a framework for analysis of present work, as well as a guide to future efforts.

Perestroika, Phase Iii: Can The Ussr Learn From The Only Successful Reform?, Phillip J. Bryson

Faculty Publications

In Phase I of Mikhail Gorbachev's tenure as chief director of the soviet economic strategy, the General Secretary seemed content to continue an approach his predecessors had referred to as plan "perfecting" (sovershenstvovanie). This approach which called merely for the development and implementation of modest improvements in the planning mechanism. It was the chosen alternative to economic reform, the approach which had been peremptorily rejected with the closing of the Kosygin reforms at the end of the 1960s.

'Favored In My Birthplace': Local Roots And Cultural Identity In Victorian Writing, Patrick G. Scott May 1991

'Favored In My Birthplace': Local Roots And Cultural Identity In Victorian Writing, Patrick G. Scott

Faculty Publications

Discusses the vocabularies in which literary critics since Matthew Arnold have described writing about place ("local," "regional," "national," "cosmopolitan," "peripheral," "central," "universal," "parochial," and "provincial"), and the differing perspectives of writers from Wordsworth to Thomas Hardy, to argue that the Victorian recognition of and ambivalence about provinciality is of lasting significance for understanding cultural identity in complex societies.

Sponsoring The Next Generation: Parental Willingness To Pay For Higher Education, Lala C. Steelman, Brian Powell May 1991

Sponsoring The Next Generation: Parental Willingness To Pay For Higher Education, Lala C. Steelman, Brian Powell

Faculty Publications

Although sociologists and economists have been widely concerned with parental investment in children, that investment has rarely been examined directly. The Parent Survey of the High School and Beyond data set provides material for examining the traits of parents and children that shape parental payment for higher education. Parents' reported willingness and ability to pay, along with savings for children's future education, are shaped first by total income and the number of children who must share that income. Moreover, parental investment in higher education is increased when the parents themselves received parental financial support, which suggests continuity over generations. Gender …

Ralph Waldo Emerson And Helen Hunt Jackson In La Edad De Oro, Anne Fountain

Faculty Publications

When Jose Martí began publication of La Edad de Oro in the summer of 1889, his purpose was to inform and to entertain the "children of America." In the four issues he published (July, August, September, October) Martí's range of topics included literary classics modified for children, original poetry, versions in Spanish of two North American poems, and a commentary on the youthful beginnings of famous writers-in sum a variety of literary lessons.While Martí is much studied and there are numerous works about La Edad de Oro, scant attention has been given to its selections from United States poetry: the …

Theory Of An Atomic Beam Splitter Based On Velocity-Tuned Resonances, Scott Glasgow, P. Meystre, M. Wilkens, E. M. Wright Mar 1991

Theory Of An Atomic Beam Splitter Based On Velocity-Tuned Resonances, Scott Glasgow, P. Meystre, M. Wilkens, E. M. Wright

Faculty Publications

We develop the theory of an atomic beam splitter in which a monoenergetic beam of two-level atoms is incident normally to a classical standing-wave light field. The incident atomic wave function can be split into two coherent components with transverse momenta ±(2n + 1)fzk using velocity-tuned resonances, where n is the order of the resonance. We discuss the cases of zero- and first-order resonances in detail, and show that the velocity-tuned resonances are renormalized due to a high-frequency Stark shift. Numerical results that display the effects of a finite momentum spread in the incident atomic beam are presented.

Identifiability In Wind Estimation From Scatterometer Measurements, David G. Long, Jerry M. Mendel Mar 1991

Identifiability In Wind Estimation From Scatterometer Measurements, David G. Long, Jerry M. Mendel

Faculty Publications

The problem of identifiability of a wind vector that is estimated from wind scatterometer measurements of the radar backscatter of the ocean's surface is addressed. The traditional wind estimation approach produces multiple estimates of the wind direction. A second processing step, known as dealiasing or ambiguity removal, is used to select a single wind estimate from these multiple solutions. Dealiasing is typically based on various ad hoc considerations. The traditional wind estimation approach results in multiple solutions associated with local minima in an objective function formed from the noisy backscatter measurements. The authors discuss the question of the uniqueness of …

The Analysis Of A Model For Wave Motion In A Liquid Semiconductor: Boundary Interaction And Variable Conductivity, William V. Smith Mar 1991

The Analysis Of A Model For Wave Motion In A Liquid Semiconductor: Boundary Interaction And Variable Conductivity, William V. Smith

Faculty Publications

The theory of conducting fluids in relative motion with small conductivity is studied with a model including the Maxwell displacement current. The model is linearized, and the interaction of waves with a plane boundary in three space is studied for two orientations of the external magnetic field. It is found that two families of boundary conditions preserve energy in one orientation (external field orthogonal to the boundary), while in the other (external field parallel to the boundary) only one condition exists which preserves energy. It is shown that generalized Fourier transforms exist, generated from the generalized eigenfunction expansions. Further, it …

Set-Valued Filtering And Smoothing, Wynn C. Stirling, Darryl Morrell Feb 1991

Set-Valued Filtering And Smoothing, Wynn C. Stirling, Darryl Morrell

Faculty Publications

A theory of discrete-time optimal filtering and smoothing based on convex sets of probability distributions is presented. Rather than propagating a single conditional distribution as does conventional Bayesian estimation, a convex set of conditional distributions is evolved. For linear Gaussian systems, the convex set can be generated by a set of Gaussian distributions with equal covariance with means in a convex region of state space. The conventional point-valued Kalman filter is generated to a set-valued Kalman filter consisting of equations of evolution of a convex set of conditional means and a conditional covariance. The resulting estimator is an exact solution …

Convex Bayes Decision Theory, Wynn C. Stirling, Darryl Morrell Feb 1991

Convex Bayes Decision Theory, Wynn C. Stirling, Darryl Morrell

Faculty Publications

The basic concepts of Levi's epistemic utility theory and credal convexity are presented. Epistemic utility, in addition to penalizing error as is done with traditional Bayesian decision methodology, permits a unit of informational value to be distributed among the hypotheses of a decision problem. Convex Bayes decision theory retains the conditioning structure of probability-based inference, but addresses many of the objections to Bayesian inference through relaxation of the requirement for numerically definite probabilities. The result is a decision methodology that stresses avoiding errors and seeks decisions that are likely to be highly informative as well as true. By relaxing the …
