Transimpedance amplifier design using 0.18 um CMOS technology
(2007-07-19)This thesis examines the design of high speed transimpedance amplifiers (TIAs) in low cost complimentary metal oxide semiconductor (CMOS) technology. Due to aggressive scaling, CMOS has become an attractive technology for ... -
The complex classrooms of three award-winning Ontario high school physics teachers
(2007-07-20)Complexity theory investigates complex systems and how parts of a system give rise to collective behaviours. My thesis focuses upon the nature of the complex systems emerging within the classrooms of three award-winning ... -
Responses of zooplankton community structure and ecosystem function to the invasion of an invertebrate predator, Bythotrephes longimanus
(2007-07-20)Freshwater ecosystems face unprecedented levels of human-induced stresses and it is expected that the invasion of non-indigenous species will cause the greatest loss of biodiversity in lakes and rivers worldwide. Bythotrephes ... -
Geodesic reduction via frame bundle geometry
(2007-07-25)Reduction theory for systems with symmetry deals with the problem of understanding dynamics on a manifold with an action of a Lie group. In geometric mechanics, this problem can be formulated in the Lagrangian, Hamiltonian ... -
Prolonged dietary iron restriction alters total tissue iron but not heme iron: lack of impact on blood pressure and salt sensitivity
(2007-08-02)The World Health Organization (WHO) states that iron deficiency (ID) is the preeminent global micronutrient deficiency. Maternal ID is linked to cardiovascular disease and hypertension in offspring, and yet the impact of ... -
Data-driven estimation for Aalen's additive risk model
(2007-08-02)The proportional hazards model developed by Cox (1972) is by far the most widely used method for regression analysis of censored survival data. Application of the Cox model to more general event history data has become ... -
Assessing the spatial and temporal patterns of total mercury δ 15N and δ13C in yellow perch and their prey items from a contaminated site, St. Lawrence River, Cornwall, ON
(2007-08-02)As a result of the legacy of industrial contamination over the last century, areas of sediment deposition in the St. Lawrence River at Cornwall, ON, contain high concentrations of mercury (Hg). The popular sport-fish ... -
The effectiveness of the recovery workbook as a psychoeducation intervention for facilitating recovery in persons with serious mental illness
(2007-08-02)Objective: In this study, the effectiveness of the modified Recovery Workbook as a psychoeducational tool for facilitating recovery in persons with serious mental illness was examined. Methods: The study was a multi-center, ... -
Nonparametric statistical procedures for therapeutic clinical trials with survival endpoints
(2007-08-02)This thesis proposed two nonparametric statistical tests, based on the Kolmogorov-Smirnov distance and L2 mallows disatnce. To implement the proposed tests, nonparametric bootstrap method is employed to approximate the ... -
Fabrication and DC characterization of single electron transistors at low temperature
(2007-08-02)The metallic single electron transistor (SET) has been shown to provide charge sensitivity on the order of 10-6 e/(Hz)1/2, when operated as a charge amplifier. This makes it an ideal candidate for low-noise measurement ... -
Influence of Membrane-Damaging Agents and the Sigma Factor AlgU on the Induction of the MexCD-OprJ Efflux System of Pseudomonas Aeruginosa
(2007-08-02)The MexCD-OprJ multidrug efflux pump of Pseudomonas aeruginosa confers resistance to a range of antimicrobials. Although not expressed under normal laboratory conditions, exposure to the membrane-active biocides, chlorhexidine ... -
Synthesis and photoluminescent properties of linear and starburst compounds based on benzimidazole, 2-(2'-pyridyl)benzimidazole and 2,2'-dipyridylamine
(2007-08-02)The objective of this thesis was to explore the chemistry of series of linear and star shaped compounds based on benzimidazolyl, 2-(2’-pyridyl)benzimidazolyl, and 2,2’-dipyridylamino functional groups. These groups all ... -
Structural analysis of brittle deformation features along Grenvillian shear zones in southeastern Ontario
(2007-08-02)Brittle features along two prominent shear zones in the Grenville Province of southeastern Ontario, the Central Metasedimentary Belt boundary thrust zone (CMBbtz) and Robertson Lake mylonite zone (RLmz), are investigated ... -
Phytoextraction of lead from contaminated soil by Panicum virgatum L. (switchgrass) and associated growth responses
(2007-08-02)Growing interest in biomass crops for energy production has focused attention on Panicum virgatum L. (switchgrass) as a promising perennial feedstock native to much of North America. Switchgrass may be processed into ... -
A numerical study of galaxy mass density profiles
(2007-08-02)An understanding of the shape and nature of galaxy density profiles remains a major challenge to galaxy structure studies. The physical mechanisms thought to control these profiles include star formation rates and dynamical ... -
Climate and environmental change inferred from diatom communities in Lake Challa (Kenya-Tanzania)
(2007-08-09)Lake Challa is a 5 km2, 97m deep freshwater crater lake located at 880m elevation on the southeast slope of Mount Kilimanjaro (Kenya-Tanzania). Information gained from a preliminary limnological survey of Lake Challa, ... -
