Electricity Demand Forecasting In A Changing Regional Context: The Application Of The Multiple Perspective Concept To The Prediction Process, James Christopher Sapp

Dissertations and Theses

In 1982, the Bonneville Power Administration (BPA), a marketer of hydroelectric power in the Pacific Northwest, found itself in a new role which required it to acquire power resources needed to meet the demands of the region's utilities. In particular, it had to deal with the Washington Public Power Supply System's nuclear plant cost escalations. In response, BPA prepared its first independent regional power forecast. The forecast development process was intricate and multidimensional and involved a variety of interested parties. Application of the Multiple Perspective Concept uncovers strengths and weaknesses in this process by illuminating its technical, organizational and personal …

The Politics Of Disestablishment : Gladstone And The Fenians, Robert Emmett Lanxon

Dissertations and Theses

In early 1868 William E. Gladstone presented several bills in Parliament to disestablish the Church of Ireland. Prior to 1868 Gladstone had stated his opposition to the official connection between the Church of Ireland and the State. Gladstone, however, had also claimed that he was not in favor of immediate action and instead advocated restraint in attacking the Church of Ireland. The 1860's also saw the rise of the Fenian organization. The Fenians were dedicated to the overthrow of English rule in Ireland and the establishment of an Irish republic. The role that the Fenians played in convincing Gladstone to …

Modeling Cadastral Spatial Relationships Using An Object-Oriented Information Structure, Daniel Kjerne

Parallel Approximate String Matching Applied To Occluded Object Recognition, David Smith

Dissertations and Theses

This thesis develops an algorithm for approximate string matching and applies it to the problem of partially occluded object recognition. The algorithm measures the similarity of differing strings by scanning for matching substrings between strings. The length and number of matching substrings determines the amount of similarity. A classification algorithm is developed using the approximate string matching algorithm for the identification and classification of objects. A previously developed method of shape description is used for object representation.

Stratigraphic Model Of The Southern Portion Of The Jim Bridger Coal Field, Sweetwater County, Wyoming, Paul S. Maywood

Dissertations and Theses

Uppermost Lance and lowermost Fort Union Formation sediments are found in outcrop in the southern portion of the Jim Bridger coal field, located on the northeast flank of the Rock Springs Uplift in Sweetwater County, Wyoming. Twenty-nine surface sections and 581 subsurface (borehole) sections were evaluated and used to construct a stratigraphic model.

Stratigraphic correlations with economically mineable coal seams in the Fort Union Formation north and south of the study area combined with definition of questionable local formational boundary locations are significant objectives in this investigation.

A Seismic Refraction Study Of A Portion Of The Northeastern Margin Of The Tualatin Valley, Oregon, David John Nazy

Dissertations and Theses

The Tualatin Valley is a well defined elliptical basin centered at Hillsboro, with a major axis trending roughly N65°W. The valley is bordered on the northeast by the Tualatin Mountains (Portland Hills) which are a faulted, northwest-trending asymmetrical anticline. Topographic and geophysical evidence have defined the Portland Hills fault, which occurs along the northeast side of the Tualatin Mountains. The possibility that a fault or fault zone occurs along the southwest side of the Tualatin Mountains was investigated in this study.

Development And Application Of Some Quantitative Stratigraphic Techniques To The Coos Bay Coalfield, A Tertiary Fluvio-Deltaic Complex In Southwestern Oregon, Willard Sidney Titus Iii

Dissertations and Theses

A computer technique for interpreting geophysical logs of drill-holes in quantitative lithologic terms has been developed and tested on the deposits of the late Eocene Coaledo Formation, a well-studied fluvio-deltaic complex in southwestern Oregon. The technique involves the use of induced and natural gamma logs for separation of coal and claystone from coarse-grained detrital rocks and the use of the ratio of resistivity and natural gamma responses (defined here as the "grain size index") to divide the coarse elastic rocks into a series of textural classes corresponding to the Wentworth-Odden particle size scale.

Pentafluorosulfur (VI) bromide (SF₅Br) adds to olefins of the form CX₂=CX₂, where X= H or F, with the pentafluorosulfur group usually adding to the carbon with more hydrogens attached to it. This series of compounds was used in an attempt to prepare the corresponding sulfonic acid hydrates of the general formula SF₅CX₂CX₂SO₃H·nH₂O, in order to have these compounds tested as possible fuel cell electrolytes. The reaction scheme involved reflux of the SF₅Br adduct with an equimolar amount of sodium sulfite in 50% …

Spatial And Temporal Characteristics Of Surface Air Temperature For Portland, Oregon, Li-Min Yang

Dissertations and Theses

This study examines the spatial and temporal characteristics of the surface air temperature in Portland, Oregon. Spatial temperature patterns indicate that the dominant control factors on seasonal temperature distribution are local topography, elevation, and urban-rural differences in surface structure. A heat island exists in the Portland area; the intensity of the heat island rang€s from 4° to 10° F, and varies throughout the year. The strongest heat island is found in the July minimum temperature. Temperature distribution in Portland and the adjacent area is affected by winds and rainy conditions, but less influenced under overcast skies. The long-term temperature over …

Numerical Solutions Of Continuous Wave Beam In Nonlinear Media, Jeffrey Huang

Dissertations and Theses

Deformation of a Gaussian beam is observed when it propagates through a plasma. Self-focusing of the beam may be observed when the intensity of the laser increases the index of refraction of plasma gas.

Due to the difficulties in solving the nonlinear partial differential equation in Maxwell's wave equation, a numerical technique has been developed in favor of the traditional analytical method. Result of numerical solution shows consistency with the analytical method. This further suggests the validity of the numerical technique employed.

A three dimensional graphics package was used to depict the numerical data obtained from the calculation. Plots from …

Molecular Cloning Of Spinach Chloroplast Dna Isolated By Alkaline Lysis, Robert Gray Drager

Dissertations and Theses

Chloroplast genomes of land plants show conservation of structure and gene arrangement. The spinach chloroplast genome is comprised of a covalently closed. circular DNA molecule of 150 kilobases and is typical of these plants. Approximately 20% of the proteins found in the spinach chloroplast are encoded by the chloroplast genome and translated on chloroplast ribosomes. The remainder are encoded on chromosomes in the nucleus, translated on cytoplasmic ribosomes and transported into the chloroplast.

Spinach chloroplast DNA was isolated from crude 2 chloroplast preparations by a new method. Chloroplasts were lysed with alkaline sodium dodecyl sulfate, contaminating macromolecules precipitated with acidified …

The exposed sequence of rocks in the study area are located approximately 250 m above the base of the Ohanapecosh Formation. A lower sequence of deposits, about 350 m in thickness, are dominated by primary and reworked lithic lapilli-tuff and epiclastic channelized volcanic sandstone and conglomerate. These sediments are interpreted as pyroclastic flows and stream deposits, respectively. The upper sequence, about …

An Analysis Of The Eastern Margin Of The Portland Basin Using Gravity Surveys, Steven Allen Davis

Dissertations and Theses

The recent contributions of several investigators has indicated the Portland basin may be a pull-apart structure associated with wrench tectonism. Because of the large density contrast between sedimentary and volcanic units and because of their reasonably uniform and continuous nature, gravity survey methods can be used to identify covered structures with considerable success. The study utilized gravity modeling techniques to investigate the structure and genesis of the Portland basin's eastern margin.

Dissertations and Theses

There is a clear change in the architectural qualities of builder's houses constructed before World War II and in the postwar years. The primary evidence is in the houses themselves and their architectural qualities. This study focuses on the first 20 years of Federal Housing Administration insured mortgage builders' houses constructed in the Pacific Northwest region, although expanded with some examples from across the nation to illustrate the general application of the thesis and that this was not a regional phenomenon.

The Role Of Iron Nutrition In Regulating Patterns Of Photosynthesis And Nitrogen Metabolism In The Green Alga Scenedesmus Quadricauda, Dennis Raymond Ades

Dissertations and Theses

The influence of iron nutrition on patterns of photosynthetic behavior, nitrogen metabolism, and fixed-carbon allocation is reported for a common freshwater green alga. Cultures of Scenedesmus quadricauda were grown in Fraquil medium in which iron concentrations ranged from 1.0 μM to 0.01 μM (log 10-6 to 10-8 M, respectively). Carbon 14 and nitrogen uptake experiments were conducted at photosynthetically saturating and subsaturating photon flux densities.

Elastic-Plastic Analysis Of Axisymmetrically Loaded Isotropic Circular And Annular Plates Undergoing Large Deflections, Aiman Raji Akileh

Dissertations and Theses

The concept of load analogy is used in the elastic and elastic-plastic analysis of isotropic circular and annular plates undergoing moderately large deflection. The effects of the nonlinear terms of lateral displacement and the plastic strains are considered as additional fictitious lateral loads, edge moments, and in-plane forces acting on the plate. The solution of an elastic or elastic-plastic Von Karman type plate is hence reduced to a set of two equivalent elastic plate problems with small displacements, namely, a plane problem in elasticity and a linear elastic plate bending problem. The method of finite element is employed to solve …

A Groundwater Flow Model Of The Aquifer Intercommunication Area, Hanford Site, Washington, Elizabeth G. Simkover

Dissertations and Theses

Intercommunication has been identified between the unconfined and uppermost confined aquifer systems underlying a portion of the U.S. Department of Energy's Hanford Site. Erosional thinning and fracturing of the basalt confining layer within the study area allows physical contact between the two aquifers, but the vertical hydraulic gradient (a required driving force) is small. To better conceptualize the distribution and volume of the leakage occurring between the aquifer systems, this study investigates the confined Rattlesnake Ridge Aquifer flow system, which appears to be more sensitive to the vertical leakage than the overlying unconfined aquifer.

The flow system of the Rattlesnake …

Finding A New Voice: The Oregon Writing Community Between The World Wars, Karen Stoner Reyes

Dissertations and Theses

The period of 1919 to 1939 was a significant one for the development of the literature of Oregon and the Pacific Northwest. The literary work produced in the region prior to the first world war was greatly influenced by the "Genteel tradition" of the late nineteenth century. By 1939, however, the literature of Oregon and the region had emerged from the outdated literary standards of the pre-war period and had found a new, realistic, natural voice, strongly regional in nature and rooted in the modern American tradition.

This change came about in large part through the efforts of a small …

Geology Of The Willamette Pass Area, Cascade Range, Oregon, Neil M. Woller

Dissertations and Theses

The Willamette Pass area is situated at the intersection of two hypothesized structural features, the Western Cascade-High Cascade boundary and the Eugene-Denio lineament. It is of interest due to its designation by the U.S. Department of the Interior as a Known Geothermal Resource Area.

Volcanic rocks of Oligocene to Pleistocene age are exposed in the study area. The oldest rocks are the Oligocene-Miocene lavas, undifferentiated, which are a diverse unit of ignimbrites and intermediate to silicic flows. The Oligocene-Miocene rhyodacites are a stratigraphically equivalent unit which is predominantly composed of aphyric rhyodacite flows. Middle Miocene volcanism produced the basaltic lavas …

The Formal Language Of Nonobjective Art, Gwen M. Erickson

Dissertations and Theses

As a central issue in my thesis work, I wish to explore a growing interest in the nature of shapes and their relationship to each other and to their environment. The character or personality of a shape is defined for me by its gesture and its color. I like to join shapes with different characters in such a way that they incorporate a sense of movement. The emphasis has not been on competition or conflict, but on a kind of dynamic balance.

As I worked through a series of still life studies last winter, I felt tyrannized at first by …

An Investigation Of Resolution And Addressability Requirements For Digital Display Systems Used In Word-Processing And Computer-Aided-Drafting Applications, Stephen T. Knox

Dissertations and Theses

Two hardware factors contributing to the overall image quality of digital CRTs are display resolution and addressability. The relationship between these two factors and human performance was modeled by a metric of display quality, the Resolution Addressability Ratio (RAR), and investigated within the contexts of Word-Processing (WP) and Computer-Aided-Drafting (CAD) tasks. The findings indicate a perceptual limit to MTF bandwidth improvements, and significant differences in display quality requirements between the two applications. The regression of image quality as a function of RAR metric values resulted in an r² = 0.94 for the WP task and an r² = 0.79 for …

Care, Need, And Conceptions Of Love: A Reexamination, Janet Gruwell Morris

Dissertations and Theses

The present study examines the roles need and care play in such positive interpersonal attitudes as love, liking, attraction, and friendship, by both replicating and extending a 1982 study by Steck, Levitan, McLane, and Kelley. Subjects were presented with slightly revised Rubin Love Scales which were filled out as if by persons involved in relationships, and were asked to judge how much each hypothetical person loved, liked, was attracted to, and felt friendly toward their partner. In fact, the love scales had been divided into three components, i.e. need, care, and trust, and were filled out with each component at …

The Chemistry Of Novel Chromium(Iv) Systems And Fluorinated Hypochlorites, Joseph Onuorah Udeaja

Dissertations and Theses

Chromium(IV) has been of interest for some time because of its role as an intermediate in chromic oxidation reactions. Since there are not a great number of stable tetravalent chromium complexes known, and the use of such species as oxidizing agents has not been widely explored, the preparation, isolation and characterization of new stable tetravalent chromium species may allow chemists the opportunity to more fully understand the role which tetravalent chromium plays in oxidation reactions. The present study thus involves the synthesis of Cr(OC₄H₉)₄ and other Cr(IV) derivatives and the use of Cr(OC₄H …

Tephrostratigraphy Of The Middle Eocene Chumstick Formation, Cascade Range, Douglas County, Washington, Matthew John Mcclincy

Dissertations and Theses

This study outlines the ash (tuff) bed stratigraphy (tephrostratigraphy) in the middle Eocene Chumstick Formation of central Washington. The tuff beds provide local marker beds enabling interpretation of the stratigraphy and structure of the formation. The chemical signature of these units provides the basis on which the units can be traced over broad areas in the basin of deposition. Correlations of tuff beds were obtained over distances of 41 km.

The tephrostratigraphy of the Chumstick Formation consists of nineteen tuff marker beds. Seventeen of these units are chemically characterized in this study. Ten elements were used to fingerprint these tuff …

A Contextual Analysis Of Selected Communication Strategies Associated With Dyadic And Situation Characteristics: A Field Study, Gisele Marie Tierney

Dissertations and Theses

A contextual analysis investigation of related communication acts is concerned with the multidimensional nature of human interdependence. The communication strategy is a category of relational communication acts that can be viewed as one of the ways in which interactants promote or maintain a working consensus and enhance interpersonal discovery. Strategy use is motivated by the nature of the relationship rather than by the speaker's conscious attempts to direct outcomes.
