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 ... -
Reducing the barriers to breastfeeding : an analysis of health services in Northern Ontario
(2005)Given that there is a societal expectation that mothers of newborns initiate and maintain breastfeeding for at least six months, there is a concomitant expectation that society provide the essential services, education, ... -
Exploring Ontario's community service requirement
(2005)The thesis examines the community service requirement in Ontario high schools. As part of the new curriculum, there has been very little research examining the nature of the community service hours. A case study of a ... -
Present and future focal point seed zones for jack pine in Northwestern region of Ontario
(2005)Jack pine (Pinus banksiana Lamb.) is among the most widespread and most ecologically and economically important species for planting and direct seeding in the Lake States and throughout much of the boreal forest of Canada. ... -
The inference problem in multilevel secure databases
(2005)Conventional access control models, such as role-based access control, protect sensitive data from unauthorized disclosure via direct accesses, however, they fail to prevent unauthorized disclosure happening through ... -
Effect of gender on violent and non-violent recidivism : a meta-analysis
(2005)A large body of literature has been dedicated to understanding re-offending after release from prison - a phenomenon known as recidivism. Such research is critical both to understanding the determinants of crime and ... -
Male same-sex couples and the division of household labour
(2005)Studies on heterosexual couples show that women continue to perform the overwhelming majority of household tasks, and that factors, such as gender, parental influence, relationship status, income, education, age, and ... -
Healthy eating, exercise, weight and body image : the closer I get the better I feel
(2005)Many studies have found evidence showing that women are dissatisfied with their bodies. Self-discrepancy theory (Higgins, 1987) may be particularly applicable to this area of study due to the difference between the North ... -
Developing a generic academia mobile sport messaging system using the notion of design patterns
(2005)Designing reusable applications is vital area of research. Design patterns are an innovative notion that promotes reusability. This thesis attempts to develop generic and reusable Short Messaging Systems that can be used ... -
Disordered eating among Ontario adults and older adolescents : prevalence, co-morbidities, and healthcare utilization
(2005)Research has shown substantial co-morbidities of disordered eating with various psychological and medical indices, including alcohol dependence, substance abuse, affective disorders, depression, physical disabilities, ... -
Painting like a housewife : an inquiry into gender bias in professional art education
(2005)Primary research method consisted of in-depth interviews with 10 female artists from Thunder Bay, Northwestern Ontario, Canada. -
Adaptive backstepping based nonlinear control of an interior permanent magnet synchronous motor drive
(2005)Permanent magnet synchronous machines (PMSM) have shown increasing popularity in recent years for industrial drive applications due to the recent developments in magnetic materials, power converters, and digital signal ... -
Off the beaten track : messaging as a means to reducing depreciative behaviour in a national park
(2005)Over the 2004 peak visitor season, a covert observational study was conducted at St. Lawrence Islands National Park, Ontario, Canada to assess the extent of social trail use on two islands. The study examined the ...
