Ab Initio Single- And Multiple-Scattering Exafs Debye-Waller Factors: Raman And Infrared Data, Nicholas Dimakis, Grant Bunker

Physics & Astronomy Faculty Publications

The extended x-ray-absorption fine structure (EXAFS) Debye-Waller factor is an essential term appearing in the EXAFS equation that accounts for the molecular structural and thermal disorder of a sample. Single- and multiple-scattering Debye-Waller factors must be known accurately to obtain quantitative agreement between theory and experiment. Since the total number of fitting parameters that can be varied is limited in general, data cannot support fitting of all relevant multiple-scattering Debye-Waller factors. Calculation of the Debye-Waller factors is typically done using the correlated Debye approximation, where a single parameter (Debye temperature) is varied. However, this procedure cannot account in general for …

An Approach To Defining Greater Park Ecosystems And Its Application To Gros Morne National Park (Newfoundland), Karl Keough

Theses and Dissertations (Comprehensive)

Ecosystem management is an integrative, cooperative, adaptive approach to resource management that has evolved in response to the growing number of environmental and resource problems over the past several decades. One such problem, the threat to the world’s biodiversity, may be attributed to the destruction, degradation, and fragmentation of habitat resulting from the expanding human population, and the inability to set aside in strict nature reserves, sufficient habitat for wide-ranging mammals and fully functioning ecosystems. The Greater Park Ecosystem concept may be seen as the embodiment of ecosystem management in national parks and a response to the threat to biodiversity. …

Stakeholder Attitudes As A Resistance Toward Long-Range Management Of A Threatened Landscape: A Case Study Of Aggregate Use In The Township Of North Dumfries (Ontario), Kim Margaret Horrigan

The Township of North Dumfries is located in the rapidly expanding Municipality of Waterloo. This Township is in close proximity to Kitchener, Waterloo, Cambridge, Guelph, Hamilton, and is halfway between London and Toronto, with the primary east-west Highway 401 running through the Township. It is an unique area in that it is characterized by an abundance of prime agricultural lands, Environmentally Sensitive Policy Areas, and wetlands. In addition, the Township is underlain with a large quantity of good quality glacially derived aggregate materials. Land use conflicts have increased as a result of aggregate developers’ pressures on the resources of this …

Protection Of Wetlands In The Grand River Watershed From Non-Point Source Pollution (Ontario), Marsha Lynn Paley

Theses and Dissertations (Comprehensive)

The purpose of this study is to assess the strengths and weaknesses of the municipal official plans to protect provincially evaluated wetlands from activities causing non-point source pollution within the Grand River watershed. An integrated framework for policy analysis involving both an evaluative and normative approach assists in determining the value of wetland protection policies and recommends future actions to guide decision-making on development adjacent to wetlands. Specifically, the objectives include (a) to locate, identify and measure the total wetland area, class and number of wetlands in the Grand River watershed on an upper- and lower-tier municipal basis; (b) to …

Managing Urban Water Resources In A Developing Economy: The Case Of Owerri, Nigeria, Lawrence Chidi Anukam

Theses and Dissertations (Comprehensive)

Projections indicate that the disparity in population numbers will widen further by the year 2025 when the global population is expected to be 8.5 billion, and at that time about 84% will be living in the developing countries (World Resources Institute, 1992). The greatest proportional increase will occur in Africa, where the population is projected to nearly triple, from a 1990 level of 642 million to 1.6 billion in 2025. In 1997, the population of Nigeria alone was about 100 million, making it the largest country, in terms of population, in Africa. From 1960 to 1990, the average annual population …

Land Transformation, Highly Governed Landscapes And Landscape Health: A Case Study Of The Lower Piave Area Of Northeastern Italy, Pietro Bertollo

Theses and Dissertations (Comprehensive)

This dissertation examines the issue of biophysical landscape health. Its primary objective is to produce an interpretation of biophysical landscape health for the highly governed landscapes of the Lower Piave area of northeastern Italy. Highly governed landscapes are considered to be those which are highly controlled by humans to an even greater degree than normal cultural landscapes. An example is reclaimed agricultural landscapes such as those of the northeastern Italian coastal belt, from which the Lower Piave case study is drawn. These landscapes are highly governed because without constant human intervention, they would revert back to their former marsh state. …

A Novel Thin Film Transistor Using Double Amorphous Silicon Active Layer, Jong Hyuni Choi, Chang-Soo Kim, Byung Cheon Lim, Jin Jang

Electrical and Computer Engineering Faculty Research & Creative Works

We have fabricated a novel low off-state leakage current thin-film transistor (TFT) using a chlorine incorporated amorphous silicon [a-Si:H(:Cl)] and amorphous silicon (a-Si:H) stacked active layer, in which conduction channel is formed in a-Si:H and a-Si:H(:Cl) is photo-insensitive material. The off-state photo-leakage current of the a-Si:H(:Cl)/a-Si:H TFT is much lower than that a conventional a-Si:H TFT.

An Improved Method For Incorporating Magnetic Saturation In The Q-D Synchronous Machine Model, Keith Corzine, Brian T. Kuhn, S. D. Sudhoff, H. J. Hegner

Electrical and Computer Engineering Faculty Research & Creative Works

An improved technique for incorporating saturation into the q-d axis model (Park''s model) of a synchronous machine is proposed. By choosing magnetizing flux linkage as a state variable, iterative procedures required by traditional methods are avoided. The saturation function is represented by an arctangent function which has some distinct advantages over polynomial representations and look-up tables. In particular, the parameters of the proposed function all have physical significance and the proposed function is defined over an infinite range of flux linkage. The model is verified for steady-state and transient conditions using a laboratory synchronous machine-rectifier system similar to those commonly …

Dc Link Stabilized Field Oriented Control Of Electric Propulsion Systems, Keith Corzine, S. D. Sudhoff, Steven F. Glover, H. J. Hegner, H. N. Robey

Electrical and Computer Engineering Faculty Research & Creative Works

Induction motor based electric propulsion systems can be used in a wide variety of applications including locomotives, hybrid electric vehicles, and ships. Field oriented control of these drives is attractive since it allows the torque to be tightly and nearly instantaneously controlled. However, such systems can be prone to negative impedance instability of the DC link. This paper examines this type of instability and sets forth a readily implemented albeit nonlinear control strategy to mitigate this potential problem.

Emc Applications Of The Emap5 Hybrid Fem/Mom Code, Yun Ji, Todd H. Hubing, Mohammad Wares Ali

Electrical and Computer Engineering Faculty Research & Creative Works

EMAP5 is a numerical software package designed to model electromagnetic problems. It employs the finite element method (FEM) to analyze three-dimensional volumes, and the method of moments (MOM) to analyze the current distribution on the surface of these volumes. The two methods are coupled through the fields on the dielectric surface. This paper describes the formulation of the EMAP5 code and demonstrates how it can be used to analyze simple printed circuit board configurations

Terminal Sedation As Palliative Care: Revalidating A Right To A Good Death, George P. Smith Ii

Scholarly Articles

Not everyone finds a “salvific meaning” in suffering. Indeed, even those who do subscribe to this interpretation recognize the responsibility of each individual to show not only sensitivity and compassion but render assistance to those in distress. Pharmacologic hypnosis, morphine intoxication, and terminal sedation provide their own type of medical “salvation” to the terminally ill patient suffering unremitting pain. More and more states are enacting legislation that recognizes this need of the dying to receive relief through regulated administration of controlled substances. Wider legislative recognition of this need would go far toward allowing physicians, in the exercise of their reasonable …

Reconceiving The Role Of Section 8(B)(1)(A): 1947–1997: An Essay On Collective Empowerment And The Public Good, Roger C. Hartley

Scholarly Articles

The Taft-Hartley section 8(b)(1)(A)s union discipline cases are linked to the impending collapse of collective bargaining in two ways. At one level, they have helped cause it by denying union majorities an important tool to enforce solidarity during economic disputes with employers and thereby have contributed to the loss of worker empowerment. At another level, the union discipline cases reflect certain shifts in national sentiments with respect to the role of unions and collective bargaining in general and the accommodation of collective bargaining to the competing claims of individuals and employers in particular. This paper is about both linkages.

Zinc Phosphide Residues In Gray-Tailed Voles (Microtus Canicaudus) Fed Fixed Particles Of A 2% Grain Bait, R. T. Sterner, D. A. Goldade, R. E. Mauldin

United States Department of Agriculture Wildlife Services: Staff Publications

This study measured depelted-carcass residues of zinc phosphide (Zn₃P₂, CAS # 1314-84-7) in 8 (4 males and 4 females) gray-tailed voles (Microtus canicaudus). Six (3 males and 3 females) voles were confined individually in 1.89 dkl (5 gal) plastic pails that contained 5,2% Zn₃P₂ steamrolled- oat (SRO) groats; 2 voles (1 male and 1 female) served as analytical (unbaited) controls. Four test voles (3 males and 1female) died within 7.5 h after bait exposure; whereas, 2 test voles showed no signs of toxicosis and were euthanized 7.0 h after bait exposure. …

The Stigma Of Obesity : Beliefs About And Attitudes Toward Fat/Obese Persons, Sally Jean Clute

Dissertations and Theses

This research explores the relationship between beliefs about and attitudes toward fat/obese persons, specifically in regard to issues of attribution and perceived responsibility for the physical condition. The purpose of the research is to assess the extent to which fat/obese persons are derogated, given whether or not they are perceived to be held responsible for their fatness/obesity. It utilizes attribution theory (Heider, 1958; Jones & Davis, 1965; Kelley, 1967; Weiner, 1986), in particular, internal locus of control and issues of consensus and distinctiveness (Kelley, 1967) and controllability (Weiner, 1986). The main hypothesis is that fat/obese people will be viewed more …

Using A Realistic Job Preview To Communicate Organizational Culture, Johanna Glode

Dissertations and Theses

The present study sought to determine how organizational culture information could best be presented to job applicants for the purpose of attracting employees who will fit into an organization's culture. Attraction to the organization's culture was hypothesized to influence applicant self-selection into the company. Two different types of Realistic Job Previews (RJPs), semantic and episodic, were compared in their ability to convey information accurately about a hypothetical organizational culture. Participant knowledge of the culture was hypothesized to align objective, or actual, fit with subjective perceptions of fit.

Knowledge of the organization's culture, objective fit, subjective fit, attractiveness of the culture, …
