Simulation of wrist kinematics on the basis of a rigid body spring model
(2007-09-13)The purpose of this thesis was to create a computational wrist model that predicts carpal bone motion in order to investigate the complex kinematics of the human wrist. The tuning of this model was primarily based on in ... -
Design and Manufacture of a Fibre Reinforced Composite Safety Snap-Hook
(2007-09-26)Safety snap-hooks are a critical component of a fall-arrest system worn by individuals working at elevated heights. Current snap-hook technology has not evolved in many years, and as a result, the hooks are both heavy ... -
In-plane plane strain testing to evaluate formability of sheet steels used in tubular products
(2007-09-28)In order to effectively and efficiently hydroform new automotive components, the formability of new tubular steels must be evaluated. Standard forming limit diagrams have been used for decades to evaluate and predict the ... -
Automotive Light Assembly Failure detection
(2007-10-02)after vibration endurance testing involves manual inspection only after the test is completed. An adaptable, reliable and low cost real time monitoring and diagnostic system that would interrupt the testing operation at ... -
Experimental and Numerical Investigations of Velocity and Turbulent Quantities of a Jet Diffusion Flame
(2007-10-10)A turbulent diffusion flame that is typically used in a thermal spray coating system was analyzed in this study, as part of a diagnostic and development program undertaken by a research group at Queen’s University. ... -
Validation of a Dynamic Simulation of a Five Degree of Freedom Point Contact Joint
(2007-11-05)A new special case computer simulation to model the non-linear, three dimensional dynamic equations of motion of a five degree of freedom point contact joint has been developed and the functionality has been validated with ... -
Microstructural effects on the stability of retained austenite in transformation induced plasticity steels
(2008-01-03)Transformation Induced Plasticity (TRIP) steels have both high strength and high ductility. Retained austenite in the microstructure, upon straining, transforms to martensite and this absorbs energy and improves the work ... -
Analysis of a Flat-Plate, Liquid-Desiccant, Dehumidifier and Regenerator
(2008-01-14)A numerical model for isothermal and non-isothermal flat-plate liquid-desiccant dehumidifiers and regenerators was developed and implemented. The two-dimensional model takes into account the desiccant, water and air flow ... -
Lattice Strain and Texture Evolution During Room-Temperature Deformation in Zircaloy-2
(2008-01-14)Zircaloy-2 and its sister alloy, Zircaloy-4, have extensive applications in the nuclear industry as core components in heavy water reactors and fuel cladding in both heavy and light water reactors. Intergranular stresses ... -
Performance of Air-Air Ejectors with Multi-ring Entraining Diffusers
(2008-01-14)This research study considered subsonic short air-air ejectors with multi-ring entraining diffusers. Many references can be found for the design of air-air ejectors with solid diffusers. However, a limited amount of work ... -
Optimizing fracture management: Correlating the physical and mechanical properties of bone to computed tomography to generate an estimate of bone quality
(2008-02-05)Non-invasive estimates of bone quality are of great interest as they could potentially improve the diagnosis and treatments for bone disorders, such as osteoporosis, and could aid in preoperative planning of surgical ... -
A Study of Subsonic Air-Air Ejectors with Short Bent Mixing Tubes
(2008-04-01)An experimental and numerical study of air-air bent exhaust ejectors was carried out. The objective of the study was to determine the effect of a bend on the performance of exhaust ejectors. The ejectors consisted of ... -
Flameless Combustion of Natural Gas in the SJ/WJ Furnace
(2008-04-04)Flameless combustion in a 48 kW pilot scale furnace fired with natural gas is studied experimentally and computationally. The burner geometry involved a tunnel furnace with two separate feed streams --- one for a high ... -
