Strengthening the Precalculus Bridge: Enhancing the Precalculus Student's Understanding of Tangents to Conics, Biquadratic Equations, and Maxima and Minima
… face tremendous difficulty in high school and/or college level calculus courses. The author hopes that by introducing students to the following nontraditional three topics prior to calculus, students' understanding of calculus will be enhanced. This thesis focuses on the following …

DEVELOPMENT OF DEM-BASED METHOD FOR MAPPING STREAM POWER DISTRIBUTION OF SOUTHERN ONTARIO STREAMS
… system, a known determinant of channel form and dynamics, is a valuable component of geomorphic stream assessment procedures that, unlike current methods, is physically-based, time- and cost-effective, objective and repeatable. Continuous maps of stream power can be obtained by extracting …

Charge Interaction Effects in Epoxy with Cation Exchanged Montmorillonite Clay and Carbon Nanotubes.
… such as montmorillonite layered silicates (MLS) and hybrid systems of MLS + carbon nanotubes was investigated in cured and uncured epoxy. Epoxy nanocomposites made with cation-exchanged montmorillonite clay were found to form agglomerates near a critical concentration. Using differential scanning …

Contributions to the theory of stochastic orders
… orders. Chapter 1 contains definitions and known results that are related to our study. In Chapter 2, we introduce two new stochastic orders based on ratios of Laplace transforms, and study various properties of the new orders. Among the many properties we discover, the most interesting …

A kinematic analysis of sign language
Signed languages develop among deaf populations and employ manual communication instead of voiced communication. Stokoe attributes classify individual signs in American Sign Language (ASL) and include handshape, hand location, movement, orientation, and facial expression. Signed and oral languages …

An investigation of resistance spot welding current and time parameters for different thicknesses of SAE CR 1010 steel
… thesis investigation were: 1. To establish the maxima and minima values, within limits of the welding machine parameters: current and time, for 28 gauge, 24 gauge, 20 gauge, 18 gauge, and 16 gauge of SAE CR 1010 steel. 2. To implement and calibrate the instrumentation necessary to determine …

Interpretation of reflection seismic data by analysis of cumulative energy spectra
Where reflection seismic data are available, and in the absence of geologic control (deep reflectors, lack of drill hole data), a positive identification of the structure and lithostratigraphy of the reflectors is desirable. In this study, synthetic geologic models are generated to model thin-bed …

The relative importance of microclimate and land use to biodiversity
The extent of species' distributions, and their abundance within them, can be affected by many factors. At coarse resolutions and large spatial extents, climatic variables are often found to be important in determining the boundaries of species' ranges. However, several authors have postulated that …

Design of an internally pressurized aerostatic journal bearing for thermoacoustic engines
… engines. By taking advantage of the maxima and minima of the oscillating pressures inside the engine's cavity, the bearing does not rely on external pressurization by a pump, but is internally pressurized. The fluid film lubricated bearing is established by the continuous flow of gas …

Nondestructive inspection of load induced damage in fiber reinforced polyphenylene sulfide
… of polyphenylene sulfide (PPS) reinforced with random, continuous glass fibers, approximately 30% by weight. The investigation included both characterization of the mechanical properties and nondestructive inspection of the material. The objectives of the nondestructive inspection program were …

Inhibitory Fields in the Limulus Lateral Eye
… covers an area of 15 mm (about 30% of the eye) and contains approximately 300 ommatidia; however, less than onethird of that number receives the bulk (75%) of the inhibitory effects exerted by the small cluster in the center. The position of maximum inhibition is located at some distance from …

Spin-torque induced high frequency excitations and switching in spin-valve nanocontacts
… in the areas of mobile telecommunication and information- as well as in biomedical-technologies. In this device, a direct current flow through a nanocontact generates a spin polarized current in a spin-valve multilayer, which exerts a spin-transfer torque (STT) on the magnetic moments of a …

Optical properties of metal nanoparticles and their influence on silicon solar cells
… have been investigated by simulation and experimental techniques. The aim of this investigation was to identify how to use metal nanoparticles to improve light-trapping in silicon solar cells. To do this we require nanoparticles that exhibit a high scattering efficiency and low …

Novel applications of advanced optical microscopy for microbiology
… motility, the spatial organisation of biofilms, and the growth of bacteria in a mimetic three-dimensional (3D) culture environment. The gliding motility of Myxococcus xanthus has been described as a lateral process, and it was unclear if single bacteria were capable of moving in three dimensions. …
