(2009-06-01)A novel design for an automated uranium pellet stacking system is presented. This system is designed to replace the manual method for stacking uranium pellets for CANDU fuel bundles that is currently used at Cameco Fuel ... -
Rapid rotational foam molding of polyethylene integral-skin foamed core moldings
(2009-06-01)This thesis focuses on the design, development, and evolution of a novel patent-pending plastic processing technology entitled “Rapid Rotational Foam Molding” with special emphasis on the processing of polyethylene (PE) ... -
Design and development of a custom dual fuel (hydrogen and gasoline) power system for an extended range electric vehicle architecture
(2009-06-01)In recent decades there has been a growing global concern with regards to vehicle-generated green house gas (GHG) emissions and the resulting air pollution. Currently, gasoline and diesel are the most widely used automotive ... -
A "Communication Skills for Computer Scientists" Course
(ACM, 2009-07)This paper describes "Communication Skills for Computer Scientists," a novel undergraduate course at the University of Toronto. We describe in detail the three major instructional streams of the course: writing, speaking, ... -
Biochemical alteration of gravesoils between season and soil type
(2009-07-01)Decomposition chemistry refers to the biochemical degradation processes which occur in soft tissue as decomposition proceeds. This study aims to investigate the relationship between the release of decomposition fluids into ... -
Integration of heterogeneous data types using self organizing maps
(2009-07-01)With the growth of computer networks and the advancement of hardware technologies, unprecedented access to data volumes become accessible in a distributed fashion forming heterogeneous data sources. Understanding and ... -
Chronic effects of single intra-peritoneal injection of endosulfan on rainbow trout (Oncorhynchus mykiss) and field observations of caged rainbow in Oshawa Creek
(2009-08-01)The organochlorine pesticide endosulfan has been shown to be highly toxic to fish and there is some evidence to support that it may act as an endocrine disrupting chemical. Juvenile rainbow trout (Oncorhynchus mykiss) were ... -
Molecular characterization of GABA receptor subunits from the parasitic nematode Haemonchus contortus
(2009-08-01)Haemonchus contortus is a parasitic nematode that is controlled by several nematocides which target ion channels. We have identified two H. contortus ion channel genes, Hcounc- 49B and C that encode two GABA-gated chloride ... -
Immunomodulatory effects of dietary fibre supplementation: effects on cytokine and antibody production and lymphocyte population profiles
(2009-08-01)Gastrointestinal microflora has been shown to have a bi-directional relationship with the host immune system. A variety of fermentable carbohydrate polymers largely pass through the small intestine, providing fermentable ... -
Dynamical effects in crystalline solid state systems: theory of temperature dependent optical response of bulk gaAs and vibrational modification of C(111) 2 x 1 Surface in Comparison to Experiment
(2009-08-01)This thesis presents a new theoretical formalism which incorporates dynamical effects in atomistic electronic structure and related calculations. This research, fundamental by nature, brings about a deeper understanding ... -
Chronic toxicity of phthalates, biphenol and a Canadian bottled water stored under different light regimes using the Cnidarian Hydra Viridissima©
(2009-08-01)There is general concern whether human exposure to selected Canadian bottled waters and the chemicals which may leach from them, could potentially cause deleterious effects. This research was designed to determine whether ... -
Characterization of carbon nanotubes grown by chemical vapour deposition
(2009-08-01)Carbon nanotubes (CNTs), discovered by Ijima in 1991, are one of the allotropes of carbon, and can be described as cylinders of graphene sheet capped by hemifullerenes. CNTs have excellent electrical, mechanical, thermal ... -
Growth, survivability, and reproductive effects of pulse-dosed endosulfan on jordanella floridae (florida flagfish) over one complete life-cycle
(2009-08-01)Endosulfan is a commonly used organochlorine in Durham Region, Ontario Canada which has known toxic effects on non-target organisms including fish. This research investigated the effects of endosulfan on Florida flagfish ... -
Research on remote control of reconfigurable modular robotic system
(2009-08-01)Serial manipulators, which have large work space with respect to their own volume and occupied floor space, are the most common industrial robots by far. However, in many environments the situation is unstructured and less ... -
Design of 3-DOF parallel manipulators for micro-motion applications
(2009-08-01)This thesis presents two unique micro-motion parallel kinematic manipulators (PKM): a three degrees of freedom (3-DOF) micro-motion manipulator and a 3-DOF micro-motion manipulator with actuation redundancy. The 3-DOF ... -
