Characterizations and Probabilistic Representations of Effective Resistance Metrics
This thesis studies effective resistances of finite and infinite weighted graphs. Classical results state that it is a metric on the set of vertices of the graph and that it can be expressed completely in terms of the graph’s random walk. The first goal of this thesis is to provide a concise and …

Residual gene resistance using the crown rust of oats pathosystem
Residual gene resistance has been described as the effect of race-specific resistance genes in the host plant when the host is inoculated with a pathogen lacking the corresponding avirulence genes. Pyramiding resistance genes may produce durable, effective resistance against many pathogen races. …

Properties of p-modulus on radially symmetric infinite trees
… theoretic quantities including shortest path, effective resistance, and minimum cut. Some of these concepts have meaningful and interesting extensions to infinite graphs. For example, certain effective resistance calculations on infinite trees are known to be related to the transience or …

Circuits and passive components for radio-frequency power conversion
… condition. These networks, which are termed resistance compression networks, serve to substantially decrease the variation in effective resistance seen by a tuned rf inverter as loading conditions change. The thesis explores the operation, performance characteristics, and design of these …

Polymer material selection and testing of resistive wire arrangement for a transparent infant warming blanket
… with a 12V power supply and a 3[omega] effective resistance of the wire network. The alpha prototype of ThermoCloud is composed of thin nichrome wires arranged in parallel and sandwiched between two 0.76 mm thick sheets of PVC. The revised prototype developed in this thesis improves the …

Flows, Submodularity, Sparsity, and Beyond: Continuous Optimization Insights for Discrete Problems
… graph, such as electrical conductance and effective resistance. We explore these connections along two orthogonal directions: Making manual interventions to the graph to improve connectivity, or keeping track of connectivity so as to make faster updates. These ideas lead to the first …

The problem with alliances for the anti-fracking movement on the island of Ireland
… of these very actors can produce the most effective resistance to corporate power. In an effort to contribute to activist knowledge, this thesis aims to inform two main audiences; grassroots activists involved in the antifracking struggle and ‘professional’ environmentalists. In an attempt …

Dissecting Transcriptional Regulation of Rpp8 in Arabidopsis thaliana
… proteins must be precisely regulated to provide effective resistance, without inhibiting normal plant growth. However, little is known about R gene regulation under defense-inducing conditions. The interaction between the oomycete Hyaloperonospora parasitica and the model plant Arabidopsis …

A Novel Resistance Exercise Machine for Use in a Lower Body Negative Pressure Box to Counteract the Effects of Weightlessness
… in space, especially during long-term missions. Resistance exercise coupled with lower body negative pressure (LBNP) has been shown to be effective in counteracting some of the deconditioning related problems. This thesis describes the development of a compact and effective resistance exercise …

An Afrocentric Cultural Study of Buum Oka Dance Yaounde and Perceptions of its Relevance to African (-Canadian) Students Between the Ages of 18 and 25 in the City of Regina
… such as Buum Oku Dance could serve as a tool for effective resistance and emancipation. Drawing mainly on written and oral sources, the inquiry has used Johnson’s (1986/87) “circuit of cultural production” of the dance, that is, its historical production, its representation and audience reception …

Modeling of Electronic and Ionic Transport Resistances Within Lithium-Ion Battery Cathodes
… performance due to improved accounting of how effective resistance change with morphology and materials. The increased understanding of cell resistances will enable improved design of cells for high-power applications, such as hybrid and plug-in-hybrid electric vehicles. It was found electronic …

Shipping decarbonization through sea route optimization & Vortex generator resistance reduction
… achieve this goal, accurate prediction of ship resistance and identification of effective resistance reduction measures are crucial. This thesis presents a ship resistance evaluation model that aims to accurately predict the added resistance experienced by a ship in high seas based on its …

Sport, space and segregation Pietermaritzburg, 1900-1980
… was the beerhall, not the sports field. Effective resistance organised around sport emerged only when the authorities needed Asian and Coloured cooperation to implement group areas and at this point sport became a notable site of struggle. Ultimately sports facilities, originally a symbol …

Institutions by imposition : colonial lessons for contemporary state-building
… Why do some state-building missions produce effective and durable state institutions, while others leave a legacy of weak or dysfunctional ones? I explored these questions through a comparative study of the Japanese colonization of Taiwan (1895-1945) and the American colonization of the …

Combining and mapping QTL for fusarium head blight (FHB) resistance in wheat
… semi-humid regions around the world. Single gene resistance to FHB in wheat provides only partial resistance and also the disease severity is highly influenced by environment. Consequently multiple genes are required for effective resistance. Our hypothesis is that identifying DNA markers for type …

Falling Forward: The Governance of School Reform, Race, and the Contest for a Dignified Future in Newark, N.J.
… in the U.S. The reforms have yet to meet durably effective resistance. The three articles that comprise this dissertation address questions about how school reforms, austerity, and privatization have been made governable, specifically in relation to the: preservation of local Black political …

The international township of Auroville, Tamil Nadu, India: the routinization of charisma in a context of an inner-worldly mystical orientation
… Aurovilians. These themes point to a fundamental resistance of Aurovilians to processes related to routinization of charisma. To the extent that organizational elaboration violates their primary values, Aurovilians resist institutionalization in the form of hierarchical structures, centralization, …

Continuum Methods and Tightness Results for Non-Simple SLE and CLE: Existence, Interactions, and Metric Approximations
… approximations to the intrinsic (chemical) and resistance distance. Our main result establishes the tightness of these approximations under a general set of axioms, and that any subsequential limit defines a non-degenerate metric on the gasket which also satisfies a list of natural properties. …

[EMBARGOED] Analysis of cereal cyst nematode resistance mechanisms in barley
… approach for nematode management and four resistance loci, Rha1, Rha2, Rha3 and Rha4, have been mapped. The Rha4 locus was mapped in the Galleon/Haruna Nijo population to chromosome 5H and since Rha2 and Rha4 provide the most effective resistance against the Australian H. avenae pathotype …

AN INTEGRATED APPROACH TO THE DEVELOPMENT OF RESISTANCE TO COMMON BACTERIAL BLIGHT IN COMMON BEAN (PHASEOLUS VULGARIS)
… can reduce yields by up to 45 %. Breeding for resistance is the most sustainable control strategy, yet resistance is quantitative and influenced by pathogen diversity. Most known quantitative trait loci (QTLs) derive from Mesoamerican germplasm, leaving Andean market classes such as cranberry …
