The Artist As Entrepreneur: Long-Term Professional Bonds In Quattrocento Florence, Yael Even Jan 1992

The Artist As Entrepreneur: Long-Term Professional Bonds In Quattrocento Florence, Yael Even

Quidditas

A number of comparatively recent publications on collaboration in Quattrocento art attest to the renewed interest in reassessing the nature of professional exchange among artist. These studies continue to shed more light on the prevalence and extent of collaborative artistic undertakings in Florence during this period. Originating in archival research, the studies reject the romanticized, traditional view of Early Renaissance painters, sculptors, and architects as solitary geniuses, suggesting instead that these creative talents operated as entrepreneurs who collaborated to establish profitable careers.

The Southern Utah Expedition Of Parley P. Pratt: 1849-1850, Rick J. Fish Jan 1992

The Southern Utah Expedition Of Parley P. Pratt: 1849-1850, Rick J. Fish

Theses and Dissertations

In 1849, President Brigham Young commissioned a fifty man company, headed by Parley P. Pratt, to explore Southern Utah for possible colonization. The four month trek spanned the coldest months of the winter, and afforded some very harrowing and hazardous experiences. These events weave a heroic story filled with excitement and adventure, while simultaneously revealing the tremendous dedication and fortitude on the part of the explorers to successfully complete their mission.

Many of the Southern Utah colonies that were initiated in the subsequent years following the expedition were based on information gathered during this seven-hundred mile expedition. In addition, their …

Optimal Response To Periodic Shortage: Engineering/Economic Analysis For A Large Urban Water District, Anthony Fisher, David Fullerton, Nile Hatch, Peter Reinelt Jan 1992

Optimal Response To Periodic Shortage: Engineering/Economic Analysis For A Large Urban Water District, Anthony Fisher, David Fullerton, Nile Hatch, Peter Reinelt

Faculty Publications

The problem addressed by this study is how a large urban water district can best respond to a drought or the prospect of a drought. Specifically, what is the least cost combination of alternatives to meet periodic shortages? A solution to this problem may involve structural approaches (such as developing new local storage capacity), a mix of structural and nonstructural (such as conjunctive use combined with water exchanges or sales), or purely nonstructural approaches (such as changes in water pricing). The application is to the East Bay Municipal Utility District (EBMUD), which includes portions of Alameda and Contra Costa counties …

X-Ray Diode Using A Silicon Field Emission Photocathode, W. I. Karian, Larry V. Knight, David D. Allred, A. Reyes-Mena Jan 1992

X-Ray Diode Using A Silicon Field Emission Photocathode, W. I. Karian, Larry V. Knight, David D. Allred, A. Reyes-Mena

Faculty Publications

We have produced arrays of 10,000 sharp p-type silicon points using an etch plus oxidation method. The points were used as electron emitters. No high vacuum cesiation or high temperature cleaning was needed to observe the electron emission. These are seen to be photosensitive sources of electrons at 200 K and 300 K. They were also used to produce AlKα x-rays. This constitutes the first use of etched, point arrays for generating electrons for x-ray sources.

Chemical Percolation Model For Devolatilization: Ii. Temperature And Heating Rate Effects On Product Yields, Thomas H. Fletcher, Alan R. Kerstein, Ronald J. Pugmire, David M. Grant Jan 1992

Chemical Percolation Model For Devolatilization: Ii. Temperature And Heating Rate Effects On Product Yields, Thomas H. Fletcher, Alan R. Kerstein, Ronald J. Pugmire, David M. Grant

Faculty Publications

The chemical percolation devolatilization (CPD) model describes the devolatilization behavior of rapidly heated coal based on the chemical structure of the parent coal. Percolation lattice statistics are employed to describe the generation of tar precursors of finite size based on the number of cleaved labile bonds in the infinite lattice. The chemical percolation devolatilization model described here includes treatment of vapor-liquid equilibrium and a cross-linking mechanism. The cross-linking mechanism permits reattachment of metaplast to the infinite char matrix. A generalized vapor pressure correlation for high molecular weight hydrocarbons, such as coal tar, is proposed based on data from coal liquids. …

Chemical Structure Of Char In The Transition From Devolatilization To Combustion, Thomas H. Fletcher, Mark S. Solum, David M. Grant, Ronald J. Pugmire Jan 1992

Chemical Structure Of Char In The Transition From Devolatilization To Combustion, Thomas H. Fletcher, Mark S. Solum, David M. Grant, Ronald J. Pugmire

Faculty Publications

Coal devolatilization experiments are generally conducted separately from char oxidation experiments, and the relationship between the chars generated in the two types of research is often ignored. However, char is one of the most important products of coal devolatilization and must be characterized as a function of temperature and heating rate in a manner similar to that for gaseous devolatilization products. The chemical structure of the parent coal directly affects devolatilization behavior. In this work, the chemical structure of chars from five coals of different rank are examined, and implications on char reactivity are discussed. Chars were obtained as a …

Learn Audit Selection Rules From Data: A Genetic Algorithms Approach, David P. Greene, Rayman D. Meservy, Stephen F. Smith Jan 1992

Learn Audit Selection Rules From Data: A Genetic Algorithms Approach, David P. Greene, Rayman D. Meservy, Stephen F. Smith

Faculty Publications

The construction of expert systems typically require the availability of expertise that can be modeled. However, there are many important problems where no expertise exists, yet there is a wealth of data indicating results in different situations. Machine learning algorithms attempt to discover rules which capture the regularities that exists in such data.

Habitat Use And Food Selection Of Small Mammals Near A Sagebrush/Crested Wheatgrass Interface In Southeastern Idaho, David K. Koehler, Stanley H. Anderson Oct 1991

Habitat Use And Food Selection Of Small Mammals Near A Sagebrush/Crested Wheatgrass Interface In Southeastern Idaho, David K. Koehler, Stanley H. Anderson

Great Basin Naturalist

Habitat use and food selection data were collected for deer mice (Peromyscus maniculatus), montane voles (Microtus montanus), Ord's kangaroo rats (Dipodomys ordii), and Townsend's ground squirrels (Spermophilus townsendii) near a sagebrush (Artemisia tridentata )/crested wheatgrass (Agropyron cristatum) interface in southeastem Idaho. Significantly more captures occurred in the native sagebrush habitat than in areas planted in crested wheatgrass or in disturbed sites. Crested wheatgrass, a prolific seed producer, still accounted for over 30% of the total captures. Montane voles and Townsend's ground squirrels (during periods of aboveground activity) used the …

Nest-Site Selection By Sage Thrashers In Southeastern Idaho, Kenneth L. Petersen, Louis B. Best Oct 1991

Nest-Site Selection By Sage Thrashers In Southeastern Idaho, Kenneth L. Petersen, Louis B. Best

Great Basin Naturalist

Nest sites selected by Sage Thrashers (Oreoscoptes montanus) in southeastern Idaho were characterized and compared with available habitat. Microhabitats within 5 m of nests had taller and more aggregated shrubs and less bare ground than the study area in general. Big sagebrush (Artemisia tridentata wyomingensis) plants used for nesting were taller than average available shrubs, had greater foliage density, were more often living, and more frequently had branches and foliage within 30 cm of the ground. Nest placement was specific with respect to relative nest height and distance from the top and perimeter of the support …

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 …

Bromus Invasions On The Nevada Test Site: Present Status Of B. Rubens And B. Tectorum With Notes On Their Relationship To Disturbance And Altitude, Richard Hunter Jun 1991

Bromus Invasions On The Nevada Test Site: Present Status Of B. Rubens And B. Tectorum With Notes On Their Relationship To Disturbance And Altitude, Richard Hunter

Great Basin Naturalist

Bromus rubens and Bromus tectorum are now nearly ubiquitous components of the Nevada Test Site (NTS) flora. Introduced to the western United States in the late 1800s, they spread through the Mojave and Great Basin deserts in the early twentieth century. Since quantitative studies began on the NTS in 1957; Bromus spp. have greatly increased in frequency and density. By 1988 both species occurred in many places at densities exceeding 1000 individuals per square meter. They may significantly increase flammability of the vegetation and reduce success of native ephemeral species.

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.

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.

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 …

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 …
