Designing a secure ubiquitous mammography consultation system
(2004)This thesis attempts to design and develop a prototype for mammography image consultation that can work securely within a ubiquitous environment. Mammogram images differ largely from other type of images and it requires ... -
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 ... -
Indirect key derivation schemes for key management of access hierarchies
(2004)In this thesis, we study the problem of key management within an access hierarchy. Our contribution to the key management problem is an indirect key derivation approach we call the HMAC-method. It is called the HMAC-method, ... -
Rare and exotic mineralogy of the western subcomplex of the Deadhorse Creek "diatreme", Northwestern Ontario
(2004)The Deadhorse Creek ‘Diatreme’ is a Proterozoic vent breccia that probably formed in response to early mid-continent rifting. Following emplacement of the breccia, the western subcomplex experienced three alteration ... -
Stage of change : relation to risk factors for binge eating and other health-risk behaviours among university women
(2004)The transtheoretical model delineates the different stages that individuals go through as they change maladaptive behaviours: precontemplation, contemplation, action, and maintenance (Prochaska, DiClemente, & Norcross, ... -
Pre- and post-forest management investigations of factors affecting sediment movement in riparian areas in Northwestern Ontario
(2004)The principal objectives of this study were to measure the impacts of timber harvesting on sediment transport rates (mineral and organic) associated with two clearcut areas in northwestern Ontario and to evaluate the ... -
Mindfulness-based cognitive therapy (MBCT) for stroke survivors : an application of a novel intervention / by Amy K. Moustgaard. --
(2004)Stroke can affect neurological, cognitive, and emotional functioning and have a negative impact on overall quality of life (QoL). Published research in the area of psychological intervention for stroke patients suggests ... -
Shoreline forest disturbance rates in natural and managed forests of northwestern Ontario
(2004)The purpose of this study was to compare the rates of disturbance along forested shorelines between natural and managed forests of the mesic boreal region of northwestern Ontario. Comparisons were made between areas that ... -
Dating preferences in later life
(2004)Proponents of evolutionary theory assert that mate selection preferences are affected by the biology of reproduction, and that sex differences in mate preferences reflect biological differences regarding reproduction. ... -
Study of two different tunable vibration absorbers : variable stiffness absorber and variable damping absorber
(2003)A structure or machine w ill vibrate at the frequency of excitation when excited by a harmonic force. Vibration of the structure can be suppressed using a vibration absorber by setting the absorber’s natural frequency ... -
Effects of bright light intervention on typical and atypical depressive symptoms and predictors of response
(2004)The objective of the present study was to investigate within a prospective design the seasonality and depression predictors of light therapy response after controlling for treatment expectancy and pre-therapy functioning. ... -
Weaving the literary quilt : the layering of narrative in Thomas King's Truth & Bright Water
(2004)This thesis explores the ways in which Thomas King layers levels of textual and symbolic narrative in order to show that truth is a relative concept that cannot be strictly bound by conventional, essentialist beliefs. In ... -
No man is a failure who has friends : the role of adaptive inferential feedback in hopelessness depression / Lize R. Jalbert. --

Study of heteroaromatic enediyne and substituted benzothiophene synthesis with a study of unusual H NMR signals in neomenthyl halides
(2004)The synthesis of a number of heteroaromatic enediynes has been examined using the Sonogashira coupling reaction. Alkynes were coupled to 2,3-dibromothiophene to yield a number o f hetero- and homo-disubstituted enediynes. ... -
