Hydrological Response Patterns And Solute Flux In Canadian Shield Basins: Role Of Different Physical Features And Antecedent Moisture Conditions, Jessica Mueller

Theses and Dissertations (Comprehensive)

Patterns of stream flow in relatively undisturbed Canadian Shield basins are closely linked to their physical and vegetative characteristics and meteorological conditions. The physical characteristics include topography, soil-till composition, depth and structure, slope morphology and bedrock geology. Hydrological flowpaths through, and in-situ chemical processes in the soil-till matrix are influenced greatly by the composition of these features and by the antecedent hydrological conditions preceding a given storm or snowmelt event.

A long term data set, collected by the Dorset Environmental Science Centre, is used to examine eight forested basins within the Muskoka-Haliburton region of south-central Ontario. The basins have a …

Origin Of Intentionality, Darryl J. Murphy

Theses and Dissertations (Comprehensive)

The modern origins of intentionality reside in the early work of Franz Brentano—specifically, his Psychology from an Empirical Standpoint (1876) and the notion of the “intentional inexistence” of the object of consciousness presented therein. “Intentional inexistence”, says Brentano, is the fundamental distinguishing characteristic of the objects that occupy our desires, aversions, thoughts, and all of our conscious activities in general. According to Brentano, “Aristotle himself spoke of this mental inexistence. In his book on the soul he says that the sensed object, as such, is in the sensing subject; that the sense contains the sensed object without its matter; that …

How Not To Be An Atheist: A Neoclassical Response To The New Atheism, Donald W. Viney

Faculty Submissions

The New Atheists (e.g. Richard Dawkins, Sam Harris, Daniel Dennett, Christopher Hitchens, and Victor Stenger) claim that a commitment to science, reason, and morality is inconsistent with theism. Using as my point of departure neoclassical theism as expounded in the works of A. N. Whitehead, Charles Hartshorne, and Pierre Teilhard de Chardin, I argue that the New Atheism is intellectually anemic, interesting though it is as political activism. The New Atheists criticize a caricature of faith, offer inferior versions of old arguments, commit the mistake of construing theism as a scientific hypothesis, and ignore sophisticated forms of belief in God.

Advancing Epidemiological Science Through Computational Modeling: A Review With Novel Examples, Scott M. Duke-Sylvester, Eli N. Perencevich, Jon P. Furuno, Leslie A. Real, Holly Gaff

Biological Sciences Faculty Publications

Computational models have been successfully applied to a wide variety of research areas including infectious disease epidemiology. Especially for questions that are difficult to examine in other ways, computational models have been used to extend the range of epidemiological issues that can be addressed, advance theoretical understanding of disease processes and help identify specific intervention strategies. We explore each of these contributions to epidemiology research through discussion and examples. We also describe in detail models for raccoon rabies and methicillin-resis-tant Staphylococcus aureus, drawn from our own research, to further illustrate the role of computation in epidemiological modeling.

Web Search Algorithms And Pagerank, Laleh Samarbakhsh

Theses and Dissertations (Comprehensive)

The mathematical theory underlying the Google search engine is the PageRank algorithm, first introduced by Sergey Brin and Lawrence Page, the founders of Google. A ranking of web pages is made considering many criteria. PageRank exploits the graph structure of the web. The web’s hyperlink structure forms a massive directed graph, where the web pages are presented as nodes and hyperlinks as edges. The PageRank equation finds a score by solving a recursive equation which calculates the PageRank vector. The PageRank vector is the stationary distribution of an ergodic Markov chain. The Perron-Frobenius theorem ensures that the primitive matrix produced …

A Critical Examination Of Sustainability Considerations In Yukon Environmental Assessment—Past And Present, Louisa M. Clementino

Theses and Dissertations (Comprehensive)

The Northern regions of Canada, as a result of landscape characteristics and political and cultural dynamics, present unique challenges and opportunities for meeting sustainability goals through environmental assessment (EA) processes. In order to understand the significance of the EA process in the North and its applicability to fulfilling sustainability goals, the past and present EA regimes of the Yukon are evaluated adopting a sustainability-focused framework. Unique changes to the Yukon EA process, as a result of land claim agreements and devolution have created innovative structures and processes, reflective of the environmental, socio-economic, cultural and political circumstances of the region. The …

Social Behavior Inventory: To Ipsatize Or Not To Ipsatize, That Is The Question, Carolyn Hoessler

Theses and Dissertations (Comprehensive)

This research extends prior knowledge of the statistical procedure of ipsatization, commonly utilized in interpersonal research to align data with theoretical expectations. The working hypotheses in prior studies have posited that a general factor, representing a response bias with no relevant substantive meaning, alters the data and interferes with analysis and interpretation unless removed by ipsatization. In the first of two studies, we initially investigated whether ipsatization removes important conceptual information from data when it removes a general factor. Three potential meanings of the general factor expected to occur in the Likert-scale version of the Social Behavior Inventory (SBI; Moskowitz, …

The Application Of Environmental Impact Assessment Legislation To The 2010 Winter Olympic Games Venue And Infastructure Development, Daniel Melbourne Patterson Kellar

Theses and Dissertations (Comprehensive)

Environmental impact assessment (EIA) is a tool which aims to make developments better by identifying, avoiding, and mitigating potential negative environmental impacts of projects and other action. With the 2010 Winter Olympic Games being held in the Vancouver to Whistler (sea-to-sky) corridor many developments have been initiated and EIA has played a role in 2010 site construction. Using case study analysis, legislative and literature reviews as well as open-ended interviews with key participants, stakeholders, and partners in the environmental impact assessment process, this study investigated the application of Canada’s and British Columbia’s environmental impact assessment legislations to the 2010 Olympic …

Oviposition Behavior Partitions Aquatic Landscapes Along Predation And Nutrient Gradients, C. A. Binckley, W. J. Resetarits Jr.

Biological Sciences Faculty Publications

That individuals attempt to minimize the ratio of mortality risk/growth rate (μ/g) when foraging within individual habitat patches is well established. Do species partition among spatially discrete communities embedded in complex landscapes in a similar manner? We investigated how 3 ovipositing species (2 Hyla treefrogs and a hydrophilid beetle, Tropisternus lateralis) responded to simultaneous gradients of nutrients and predation risk. Species partitioned our experimental metacommunity primarily by reducing oviposition with fish. Tropisternus positively responded to increased nutrients, but the effect decreased with increasing risk, as predicted by μ/g theory. Use of fish habitats by Tropisternus was unrelated to breeding …

Swimming Dynamics And Propulsive Efficiency Of Squids Throughout Ontogeny, Ian K. Bartol, Paul S. Krueger, Joseph T. Thompson, William J. Stewart

Biological Sciences Faculty Publications

Synopsis Squids encounter vastly different flow regimes throughout ontogeny as they undergo critical morphological changes to their two locomotive systems: the fins and jet. Squid hatchlings (paralarvae) operate at low and intermediate Reynolds numbers (Re) and typically have rounded bodies, small fins, and relatively large funnel apertures whereas juveniles and adults operate at higher Re and generally have more streamlined bodies, larger fins, and relatively small funnel apertures. These morphological changes and varying flow conditions affect swimming performance in squids. To determine how swimming dynamics and propulsive efficiency change throughout ontogeny, digital particle image velocimetry (DPIV) and kinematic …

New Particle Formation In The Front Range Of The Colorado Rocky Mountains, Micahel Boy, Thomas Karl, Andrew Turnipseed, Roy Lee Mauldin, Edward Kosciuch, James Greenberg, Jeff Rathbone, James Smith, Andreas Held, Kelley Barsanti, Alex Guenther

Civil and Environmental Engineering Faculty Publications and Presentations

New particle formation is of interest because of its influence on the properties of aerosol population, and due to the possible contribution of newly formed particles to cloud condensation nuclei. Currently no conclusive evidence exists as to the mechanism or mechanisms of nucleation and subsequent particle growth. However, nucleation rates exhibit a clear dependence on ambient sulphuric acid concentrations and particle growth is often attributed to the condensation of organic vapours. A detailed study of new particle formation in the Front Range of the Colorado Rocky Mountains is presented here. Gas and particle measurement data for 32 days was analyzed …

Daily Forecasts Of Columbia River Plume Circulation: A Tale Of Spring/Summer Cruises, Yinglong J. Zhang, Antonio M. Baptista, Barbara M. Hickey, Byron C. Crump, David A. Jay, Michael Wilkin, Charles Seaton

Civil and Environmental Engineering Faculty Publications and Presentations

Semi-operational daily forecasts of circulation from an observatory for the Columbia River estuary-plume-shelf system routinely support oceanographic cruises, by providing 24h-ahead estimates of plume location and structure for planning purposes and for near real-time interpretation of observations. This paper analyzes forecast skill during spring/summer cruises in 2004-2007. Assessment addresses both qualitative descriptions of major plume trends and features and quantitative representation of data from (primarily) vessel-based flow-through, cast and towed systems. Forecasts emerge as robust predictors of plume location and variability, with skill that has grown over time, at least in part due to improvements in model algorithms. When the …

Minimization Of Halftone Noise In "Flat" Regions For Improved Print Quality, Harsha Narne

Theses

The work in this thesis proposes a novel algorithm for enhancing the quality of "flat" regions in printed color image documents. The algorithm is designed to identify the "flat" regions based on certain criteria and filter these regions to minimize the noise prior and post Halftoning so as to make the hard copy look visibly pleasing. Noise prior to halftone process is removed using a spatial Gaussian filter together with a Hamming window, concluded from results after implementing various filtering techniques. A clustered dithering is applied in each channel of the image as Halftoning process. Furthermore, to minimize the post …

The Impact Of A Professional Learning Community On Student Achievement, Brandon S. Carter

Walden Dissertations and Doctoral Studies

Professional learning communities (PLC) have the potential to strengthen students' academic achievement. An academic pyramid of interventions, one aspect of PLCs, may be especially helpful in schools where subgroups of students are underperforming relative to other students on standardized testing. This quantitative, one-group, pretest-posttest study examined the impact of implementing an academic pyramid of interventions as part of a PLC on middle school student academic achievement. The 100 students from grade 7 and 8 who participated in the study were identified by teachers as being at-risk for success on the Criterion Referenced Competency Test (CRCT). The reading and math test …

Parameter Estimation And Life Modeling Of Lithium-Ion Cells, Shriram Santhanagopalan, Qi Zhang, Karthikeyan Kumaresan, Ralph E. White

Faculty Publications

Lithium-ion pouch cells were cycled at five different temperatures (5, 15, 25, 35, and 45°C ), and rate capability studies were performed after every hundred cycles. The data were used with a simple physics-based model to estimate parameters that capture the capacity fade in the cell, with cycling. The weight of active material within each electrode was estimated as a function of time, using rate capability data at the C/33 rate. The C-rate for these cells is 1.656 A. The capacity fade due to the loss of active material and that due to the loss of cyclable lithium …

Thermal Model For A Li-Ion Cell, Karthikeyan Kumaresan, Godfrey Sikha, Ralph E. White

Faculty Publications

A thermal model for a lithium-ion cell is presented and used to predict discharge performance at different operating temperatures. The results from the simulations are compared to experimental data obtained from lithium-ion pouch cells. The model includes a set of parameters (and their concentration and temperature dependencies) that has been obtained for a lithium-ion cell composed of a mesocarbon microbead anode, LiCoO₂ cathode in 1 M LiPF₆ salt, in a mixture of ethylene carbonate, propylene carbonate, ethyl-methyl carbonate, and diethyl carbonate electrolyte. The parameter set was obtained by comparing the model predictions to the experimental discharge profiles obtained …

Analytical Expression For The Impedance Response For A Lithium-Ion Cell, Godfrey Sikha, Ralph E. White

Faculty Publications

An analytical expression to predict the impedance response of a dual insertion electrode cell (insertion electrodes separated by an ionically conducting membrane) is presented. The expression accounts for the reaction kinetics and double-layer adsorption processes at the electrode-electrolyte interface, transport of electroactive species in the electrolyte phase, and insertion of species in the solid phase of the insertion electrodes. The accuracy of the analytical expression is validated by comparing the impedance response predicted by the expression to the corresponding numerical solution. The analytical expression is used to predict the impedance response of a lithium-ion cell consisting of a porous LiCoO …

A Mathematical Model For A Lithium–Sulfur Cell, Karthikeyan Kumaresan, Yuriy Mikhaylik, Ralph E. White

Faculty Publications

A mathematical model is presented for a complete lithium–sulfur cell. The model includes various electrochemical and chemical (precipitation) reactions, multicomponent transport phenomena in the electrolyte, and the charge transfer within and between solid and liquid phases. A change in the porosity of the porous cathode and separator due to precipitation reactions is also included in the model. The model is used to explain the physical reasons for the two-stage discharge profiles that are typically obtained for lithium–sulfur cells.

Responsive In-Season Nitrogen Management For Cereals, J.F. Shanahan, N. R. Kitchen, W. R. Raun, James S. Schepers

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Current nitrogen (N) management strategies for worldwide cereal production systems are characterized by low N use efficiency (NUE), environmental contamination, and considerable ongoing debate regarding what can be done to improve N fertilizer management. Development of innovative strategies that improve NUE and minimize off-field losses is crucial to sustaining cereal-based farming. In this paper, we review the major managerial causes for low NUE, including (1) poor synchrony between fertilizer N and crop demand, (2) uniform field applications to spatially variable landscapes that commonly vary in crop N need, and (3) failure to account for temporally variable influences on crop N …

Asas Centennial Paper: Net Energy Systems For Beef Cattle – Cattles, Application, And Future Models, Calvin Ferrell, J. W. Oltjen

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Development of nutritional energetics can be traced to the 1400s. Lavoisier established relationships among O₂ use, CO₂ production and heat production in the late 1700s, and the laws of thermodynamics and law of Hess were discovered during the 1840s. Those discoveries established the fundamental bases for nutritional energetics and enabled the fundamental entity ME = retained energy + heat energy to be established. Objectives became: 1) to establish relationships between gas exchange and heat energy, 2) to devise bases for evaluation of foods that could be related to energy expenditures, and 3) to establish causes of energy expenditures. …

Using A Contingency-Based Method For Combining Individual Assessment Center Dimension Ratings Into Overall Assessment Ratings, Keisha Wicks

Electronic Theses and Dissertations

The current study applies a newly proposed mechanical combination method along with four traditional mechanical combination methods to assessment center scoring. These comparisons were made for two job levels (Fire Lieutenant and Fire Captain). The study further assesses the level of adverse impact for the various methods at three cut-off scores. Results indicated that the new contingency-based scoring method was successfully implemented in the assessment center. Results were mixed regarding whether the contingencies developed for the two job levels were different. Further, results indicated that although the various combination methods were highly correlated as expected, there were clear distinctions in …
