Transport-theory-equivalent diffusion coefficients for node-homogenized neutron diffusion problems in CANDU lattices
(2010-04-01)Calculation of the neutron flux in a nuclear reactor core is ideally performed by solving the neutron transport equation for a detailed-geometry model using several tens of energy groups. However, performing such detailed ... -
Characterization of a novel cellulose biosynthesis inhibitor, CBI28, in Gluconacetobacter xylinus
(2010-05-01)To study the underlying mechanisms for microbial cellulose biosythesis, a novel compound, CBI28, was used as an inhibitor along with classical genetics and EMS mutagenesis. An EZ-Link Biotin Hydrazide Kit was used to create ... -
Profile extrusion of wood plastic cellular composites and formulation evaluation using compression molding
(2010-05-01)Wood Plastic Composites (WPCs) have experienced a healthy growth during the last decade. However, improvement in properties is necessary to increase their utility for structural applications. The toughness of WPCs can be ... -
Energy use analysis and technology for electric transit buses
(2010-05-01)Electric vehicles offer a method of transportation where the energy generation process is moved from the on-board engine to the electrical generation system. The Canadian electrical generation mix has a significant portion ... -
Applications and numerical investigation of differential-algebraic equations
(2010-05-01)Differential-algebraic equations (DAEs) result in many areas of science and engineer- ing. In this thesis, numerical methods for solving DAEs are compared for two prob- lems, energy-economic models and traffic flow models. ... -
Optimization algorithms in compressive sensing (CS) sparse magnetic resonance imaging (MRI)
(2010-06-01)Magnetic Resonance Imaging (MRI) is an essential instrument in clinical diag- nosis; however, it is burdened by a slow data acquisition process due to physical limitations. Compressive Sensing (CS) is a recently developed ... -
Thermochemical energy storage systems: modelling, analysis and design
(2010-07-01)Thermal energy storage (TES) is an advanced technology for storing thermal energy that can mitigate environmental impacts and facilitate more efficient and clean energy systems. Thermochemical TES is an emerging method ... -
Effects of soy and milk ferments on measures of innate immunity: a comparison of effects in normal and microgravity conditions
(2010-07-01)Probiotics can influence intestinal responses and mucosal immunity either directly or indirectly through transient modulation of the endogenous microenvironment or the immune system. During space travel, astronauts experience ... -
A geophysical and biochemical investigation of buried remains in contrasting soil textures in southern Ontario
(2010-08-01)Ground penetrating radar (GPR) is a non-invasive, geophysical tool used for the detection of clandestine graves. GPR operates by detecting density differences in soil by the transmission of high frequency electromagnetic ... -
Molecular characterization of the binding site of nematode GABA-A receptors
(2010-08-01)Haemonchus contortus is a parasitic nematode that is controlled in large part by nematocidal drugs that target receptors of the parasitic nervous system. Hco-UNC-49 is a nematode GABA receptor that has a relatively low ... -
The Pharmacological Characterization of Hco-UNC-49, a GABA-gated Chloride Channel from the Parasitic Nematode Haemonchus contortus
(2010-08-01)Compared to mammals, nematodes appear to exhibit a unique GABAergic nervous system. Haemonchus controtus is a parasitic nematode that infects ruminants worldwide. Hco-UNC-49 is a H. contortus GABA-gated chloride channel ... -
A survey of algebraic algorithms in computerized tomography
(2010-08-01)X-ray computed tomography (CT) is a medical imaging framework. It takes measured projections of X-rays through two-dimensional cross-sections of an object from multiple angles and incorporates algorithms in building a ... -
Integration of component-based frameworks with sensor modeling languages for the sensor web
(2010-08-01)The goal of this thesis is to develop an easily modifiable sensor system. To achieve this goal SensorML (an XML based sensor language) is combined with Java Beans (a component model language). An important part of SensorML ... -
Piezoelectric flexing and output voltage of a microchannel heat engine
(2010-08-01)In this thesis, a new model is formulated for a piezoelectric membrane and fluid motion in a microchannel heat engine. A new slug flow model is developed for droplet motion in a circular cross-section channel. The model ... -
Optomal three-time slot distributed beamforming for two-way relaying
(2010-08-01)In this study, we consider a relay network, with two transceivers and r relay nodes. We assume that each of relays and the two transceivers have a single antenna. For establishing the connection between these two transceivers, ... -
Optimal power minimization in two-way relay network with imperfect channel state information
(2010-08-01)We study a two-way amplify and forward relay network with two transceivers which communicate through a network of nr relays while there is no direct link between the two transceivers. Each relay is equipped with a single ... -
