Study of heteroaromatic enediyne and substituted benzothiophene synthesis with relative reactivity of substituted aryl iodides in the Sonogashira reaction
(2006)Enediyne compounds have captured the imagination of chemists since their discovery as a class of natural products. Because of their cytotoxicity, these compounds are not suitable for use in cancer treatment. As a result, ... -
Differential item and test functioning of the Brief Child and Family Phone Interview in First Nations and non-First Nations children and adolescents / by Dana Bova.
(2006)In 2001 the Ontario Ministry of Social Services mandated that all Ontario funded providers of children mental health services utilize the BCFPI (Brief Child and Family Phone Interview) which assesses emotional and behavioural ... -
Adaptive time-step control algorithm for nonlinear time-domain envelope transient
(2006)This thesis outlines a general method to analyze circuits with several time variables using a technique known as Multi Partial Differential Equation, MPDE. The key idea of MPDE is to convert the system of ordinary ... -
Synthesis and electrochemical study of Pt- and IrO2-based nanostructured materials
(2006)With ever increasing awareness that our environment is being ravaged at an alarming rate and the very seriously high rate of diabetes, there has been much research into understanding, controlling and reversing these ... -
Factors influencing women's participation in mathematical disciplines
(2006)Few high-achieving, university-bound, female high school students are choosing to pursue a mathematics degree at university. Researchers have discussed a wide range of factors that may account for this situation. This ... -
Peer acceptance, deviancy training, and victimization as predictors of adolescent problems : a search for personality moderators / by Hilary Cartwright.
(2006)"More recently, the importance of peer relationships with respect to the development of behavioural and emotional difficulties in children and adolescents has been acknowledged ... The extent to which individuals' experience ... -
"I'm with you now, I'm with you ..." : Michael Corleone as gangster figure in Mario Puzo's and Francis Ford Coppola's The Godfather texts / by Carmela Coccimiglio.
(2006)This thesis examines the construction of the gangster figure as embodied by Michael Corleone in Francis Ford Coppola’s The Godfather, The Godfather Part II and The Godfather Part III. The examination of Michael is ... -
Students' understanding of fractions within a reform based instructional program : an action research analysis
(2006)Students have a difficult time understanding the concepts behind fraction procedures. The purpose of this study was to determine which teaching method, traditional or reform, helped students to develop a conceptual ... -
Observer-based chaos synchronization for secure communications
(2006)Chaos, with reference to chaos theory, refers to an apparent lack of order in a system that, nevertheless, obeys particular laws or rules. The chaotic signals generated by chaotic systems have some properties such as ... -
Analysis of the change in golf swing kinematics associated with learning
(2005)Success in golf depends on the precise timing and coordination of a complex movement pattern. Because of the time consuming nature of learning the golf swing, it is important to establish a more efficient teaching and ... -
Development and evaluation of inductive and deductive models of elk (Cervus elaphus) summer resource suitability in Northwestern Ontario
(2006)Resource-selection modelling techniques take either a deductive or inductive approach. Deductive methods take a “bottom-up” approach, where individual wildlife-resource relationships are the building blocks that define ... -
Congestion and admission control in WDM optical networks
(2006)The demand for more communication bandwidth and network resources, has pushed researchers to find faster and more reliable data communication networks. Wavelength division multiplexing (WDM) is a promising technology to ... -
Study of several problems in nonlinear control by backstepping
(2005)Adaptive control is investigated for a class of nonlinearly parameterized systems by backstepping. An adaptive controller is constructed for MIMO nonlinearly parameterized systems with nested triangular form. The design ... -
Access control scheme for partially ordered set hierarchy with provable security
(2005)In many multi-user information systems, the users are organized as a hierarchy. Each user is a subordinate, superior and/or coordinate of some others. In such systems, a user has access to the information if and only if ... -
Physiological and growth responses of eleven Ontario provenances of one-year old Picea glauca seedlings to elevated CO2 concentrations
(2005)To study the physiological and growth responses of eleven Ontario provenances of white spruce [Picea glauca (Moench) Voss] to elevated atmospheric CO2 concentrations, one-year old seedlings were grown in three greenhouses ... -
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 ... -
Radio resource allocation in OFDMA system
(2006)In this thesis, orthogonal frequency division multiple access (OFDMA) system is considered. Assuming perfect knowledge of instantaneous channel conditions for all users, we propose resource allocation algorithms to ... -
Health behaviour, self-efficacy and perceived control in school-age children : foundations for obesity prevention
(2005)Understanding children’s health, as it influences their present and future lives is essential for many reasons. With the recent rapid increase in overweight and obesity among children and adolescents worldwide, the need ... -
Agent-based workflow model for enterprise collaboration
(2005)Workflow management system supports the automation of business processes where a collection of tasks is organized between participants according to a defined set of rules to accomplish some business goals. The ...
