Modeling and analysis of limit cycles in buck converters under PI control
(2005)A zero order hold equivalent discrete-time model of the buck converter for computing its large signal frequency-response is developed and experimentally verified. It is shown that with a dc bias and a sinusoidal variation ... -
Modeling and control of a flexible-link manipulator
(2001)The behaviour of a flexible-link robotic manipulator is studied using an experimental apparatus. The system is modeled based on the physical laws governing system dynamics. A non-linear rigid body model is developed which ... -
Modeling and control of various styles of paper machine headboxes
(2003)In this thesis non-linear mathematical models of a typical paper machine approach system with three different styles of headboxes are presented. The non-linear models include the dynamics of the fan pump, DC motor, ... -
Modeling and identification of an axially-moving cantilever beam
(2002)An axially-moving cantilever beam is used to study identification o f time-varying systems. A circuitry for DC motor current control and sensor conditioning is built. The circuitry meets the design requirement of controlling ... -
Modeling of PWM boost converters for continuous and discontinuous inductor current modes
(2006)Owing to the relatively more complicated nature of the boost converter with non-ideal elements and operating in continuous and discontinuous inductor current modes, a parsimonious large signal and small signal model for ... -
Modelling barred owl habitat in Northwestern Ontario
(1996)With its large home range, dependence on large decadent trees for nest cavities, and association with mature mixedwoods, the Barred Owl (Strix varia) is vulnerable to habitat loss from forest harvesting. Study objectives ... -
Modelling short-run ocean bulk carrier rates for the movement of grains
(1989)This paper, utilizing a complete market data set from Drewry Shipping Consultants, determines short-run cost functions for dry bulk carriers. Specification of the short-run to be one month and standard log-log functional ... -
Modelling, simulation and control of nonlinear flexural-flexural-inextensional rotating beam
(2004)A continuous rotating beam that undergoes flexure about two principal axes is modelled. The beam is characterized by gyroscopic type nonlinearities. The beam is of significant importance for applications such as large ... -
Modern transcendental vision of William Heyen
(1993)This paper shall attempt to outline William Heyen's Transcendental Vision. Chapter One, sections one to three, defines Transcendentalism, explores the visions of two well known American thinkers, Ralph Waldo Emerson and ... -
Modulation of Listeria monocytogenes biofilms by Pseudomonas spp. secreted substances / by Lauren Davey.
(2008)Listeria monocytogenes, a food-borne pathogen associated with severe disease, forms resistant biofilms which enable it to persist in food processing environments. Recently, surface active compounds and other microbially ... -
Molecular analysis of bacterial diversity on central venous catheters recovered from cancer patients
(2005)Central venous catheters (CVC) are a known source of nosocomial blood stream infections. However, standard cultivation methods to identify causal pathogens of catheter-related blood stream infections (CRBSI) on catheters ... -
Molecular and intramolecular relaxation processes of small molecules
(1980)The dielectric relaxation method was used to determine the activation parameters of some ethane derivatives and simple amides. A General Radio 1615-A capacitance bridge was utilized to obtain the energy barriers of the ... -
Molecular detection and identification of parasites involved in human disease
(2006)The detection and identification of disease-causing parasites via DNA and the polymerase chain reaction (PCR) offers a new approach for quick and efficient disease diagnosis. Three nucleic acid based technologies have ... -
Monitoring of training and recovery in elite cross-country skiers
(1996)The purpose of this investigation was to monitor and assess the training program of elite cross-country skiers over an eight week period in order to develop a comprehensive profile of elite crosscountry skiers. This was ... -
Mood reactivity and oral contraceptive use : do oral contraceptives act as mood stabilizers
(2006)Previous research has suggested that oral contraceptives (OCs) may provide a stabilizing effect on mood. The present study attempted to examine the differences between OC users, nonusers, and men on measures o f mood and ... -
More than just a 'value' : views of aboriginal people in Northern Ontario on aboriginal values in Ontario's forest management planning
(2006)The last decade has seen an introduction of Aboriginal values into Ontario’s forest management planning. Ontario forest management regulations and forest management research, however, are lacking spatial definitions of ... -
Morphological variation in subalpine fir and its relationship to balsam fir in western Canada and the United States
(1988)To help clarify the taxonomy of the two closely related North American firs subalpine fir {Abies lasiocarpa (Hook.) Nutt.) and balsam fir {Abies balsamea (L.) Mill.) in western Canada and the United States, 10 populations ... -
Morphology and phylogeny of the Elaphostrongylinae : (Nematoda: Protostrongylidae)
(1992)The morphology of elaphostrongyline nematodes parasitizing North American cervids was studied using light and scanning electron microscopy in order to improve previous descriptions that were based exclusively on light ... -
The mother figure in the history plays of William Shakespeare
(1976)I have chosen the topic of the mother figure in the history plays of William Shakespeare because it is a subject that has not received as much attention as other, perhaps more important aspects of Shakespeare's work that ...
