Revision of the nearctic species of the Cicindela sylvatica group (Coleoptera: Cicindelidae)
(1983)Interspecific and intraspecific variation of C. longilabris Say and C. nebraskana Casey were studied by means of discriminant analysis of morphometric data and univariate analysis of qualitative characters of adult ... -
Rewording elder abuse : a test of six frameworks
(2001)The term “elder abuse” carries powerful connotations and preconceptions, making the topic a difficult one to broach. In order to effectively reach older adults, their family members and caregivers, educators would do ... -
RF coils design for small animal MRI lung imaging at 3T using hyperpolarized 129Xe and inert fluorinated gases
(2014-01-22)This thesis described the investigation, construction and testing of two sets of RF coils for their applications in novel lung MRI imaging techniques. In the first part of the thesis, a quadrature-driven birdcage coil for ... -
Riparian habitat and vegetation recovery of headwater streams after clearcut harvesting
(2009)In this thesis I examined two important aspects of clearcut harvesting along small headwater streams and their riparian zones. The objectives of the study were: 1) to investigate the impacts of clearcut harvesting on the ... -
Riparian vegetation patterns and links with surface waters in the boreal forest
(2007)Riparian areas in the Canadian boreal forest represent the transition zone between terrestrial and aquatic ecosystems. Factors that influence riparian vegetation communities and the associated interactions with boreal ... -
Riparian vegetation response to clearcutting along small streams of boreal forest / by Shekhar R. Biswas.
(2008)In this thesis I examined three important ecological questions to understand the role of forest management disturbance on unmapped small stream riparian plant communities: I) how do small stream riparian plant communities ... -
Rise of the machine: the making of the video game industry and military simulation
(2014-01-22)Rise of the Machine assesses the history and development of the home video game industry and its technological evolution from a military industrial structure that has its roots in the Second World War. The thesis focuses ... -
Rise up!? : an analysis of appreciative resistance in environmental education / by Blair Niblett.
(2008)This thesis explores the relationship between the concepts of education and activism. I suggest that educators can approach activism in ways that are consistent with the aims of education. In support of this suggestion, I ... -
Risk sensitive foraging by rats in the operant arena
(1988)The operant arena was used as the framework in which to study the theory of risk-sensitivity, A small colony of hooded rats was exposed to increasing work demands while given the choice between simultaneous fixed ratio ... -
Risk-sensitivity in a rat population under interval schedules of reinforcement : open and closed economies
(1995)A group consisting of eight male Hooded rats was tested for risk-sensitive foraging preferences in an eight station operant arena, under conditions of open and closed economies. The group could choose to forage at either ... -
Risky riding: a comparison between two personality theories on motorcyclist riding behaviour
(2018)Motorcyclists have the highest likelihood of being involved in a fatal crash of all vehicle passengers. Given the multiple human factors that contribute to crash involvement, few personality models have been utilized to ... -
Road-network location heuristics for the tactical harvest-scheduling model
(2022)In tactical planning in hierarchical forest management, cut-blocks are selected for maximizing revenue and road networks are allocated at minimal cost in order to maximize profit. The selected cut-block set and requisite ... -
Roadside floristic patterns and revegetation by using native plants in Terra Nova National Park, Newfoundland, Canada
(2004)This thesis reports on a study of roadside floristic patterns and revegetation (cultural methods) of newly constructed roadsides by using native plants along Trans Canada Highway (TCH) in Terra Nova National Park (TNNP), ... -
Robust and adaptive control via backstepping technique
(2005)Most of the control systems are designed using linear techniques, which have been well developed. Practical physical systems are typically nonlinear. Nonlinear control is one of the biggest challenges in modern control ... -
Robust control of DC-DC boost converter / by Hisham Mahmood.
(2008)In this thesis, a robust controller comprising of a PI with phase-lead compensator for a DC-DC boost converter designed using classical frequency response method is presented. The superior performance of this controller ... -
Robust control of multi-stage web systems
(2007)Web handling systems are widely used in industries such as pulp and paper, printing press, and steel milling. Tension variations in web materials are very common in operation and tension control is critical to the quality ... -
Robust control techniques for DFIG driven WECS with improved efficiency
(2019)Wind energy has emerged as one of the fastest growing renewable energy sources since mid-80‘s due to its low cost and environmentally friendly nature compared to conventional fossil fuel based power generation. Current ... -
Robust H infinity model reference tracking control of singular systems using T-S fuzzy model and LMI
(2014-12-12)In this study, a Takagi-Sugeno fuzzy model based tracking controller is proposed for nonlinear high index singular systems with a guaranteed H1 model reference tracking performance. A coordinate transformation is introduced, ... -
Rock magnetic and structural investigation of the Moss Lake stock and local area : western Shebandowan belt
(1995)The thesis area is located 120 km west of the City of Thunder Bay, Ontario, straddling the contact of the Quetico and Wawa subprovinces of the Archean Superior Province. Metasedimentary rocks of the Quetico Subprovince ... -
