Scaphoid and Lunate Carpal Mechanics Over the Spectrum of Healthy Function
(2016-06-27)When ligaments within the wrist are damaged, the resulting loss in range of motion and grip strength can lead to reduced earning potential and restricted ability to perform important activities of daily living. Left ... -
Second Law Performance Analysis of a Large Thermal Energy Storage Vessel using CFD
(2009-09-22)This work is an example of a CFD-assisted design and characterization process for thermal energy storage vessels. A general modeling technique for future works is also proposed. The Short-Term Thermal Storage (STTS) tanks ... -
The sensitivity of articular chondrocytes to dynamic mechanical stimulation
(2016-01-05)Chondrocyte sensitization and desensitization to mechanical stimuli are complex phenomena that can limit the effectiveness of mechanical stimulation in cartilage tissue engineering. The studies in this thesis aim to provide ... -
Separated Flows Over Non-slender Delta Wings
Wings with sweep are ubiquitous for engineering applications, and are observed in biology for swimmers and fliers alike. In particular, delta wings have wide ranging applicability arising from their low speed maneuvering ... -
Shock Ignition of N-Heptane With Supplemental Hydrogen
(2014-09-13)The objective of the study was to investigate the effect of adding molecular hydrogen to a mixture of n-heptane (surrogate for diesel fuel) and air on ignition delay time at prototypic post-compression diesel engine ... -
Simulated and Experimental Kinematic Calibration of a 4 Degrees of Freedom Parallel Manipulator
(2013-01-07)This thesis discusses the kinematic calibration of the constraining linkage of a four degrees of freedom parallel manipulator. The manipulator has hybrid actuation of joints and wires, however the wires are not considered ... -
Simulated Joint Loading Enhances the Expression of of Superficial Zone Markers in Tissue Engineered Cartilage Constructs
(2012-02-28)Tissue engineering is a promising approach for repairing focal defects in articular cartilage. However, using current technologies tissue engineered cartilage displays insufficient biochemical, mechanical and structural ... -

(2016-01-18)Two identified strategies to reduce GHG emissions that threaten the global climate stability include 1)the utilization of renewable sources of energy such as solar electricity from photovoltaic (PV) devices and 2)more ... -
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 ... -
Simulations and validation of an axial-flow pit turbine
The geometric design of an axial-flow pit-turbine is essential as flow separation will decrease turbine efficiency. In this thesis, steady Reynolds Averaged Navier Stokes (RANS) simulations were conducted with a two-equation ... -
Simultaneous Topology and Build Orientation Optimization for Minimization of Additive Manufacturing Cost and Time
The ever-present demand for increased performance in mechanical systems, with reduced cost and manufacturing time, has led to the adoption of computational design tools and innovative manufacturing methods. Among these ... -
Solar Hot Water Heater Augmented with PV-TEM Heat Pump
(2014-07-04)Solar assisted heat pumps (SAHPs) can provide higher collector efficiencies and solar fractions when compared against standard solar hot water heaters. Vapour compression (VC) heat pumps require environmentally hazardous ... -
Solar Photovoltaic Resource Assessment From The Macro Scale To The Meso Scale Using Airborne Laser Scanning Data And Open Source Tools
An understanding of the urban local potential (roof space and solar exposure) is critical for utility planning, accommodating grid capacity, deploying financing schemes and formulating future adaptive policies to take ... -
Spatial and Temporal Performance Characteristics in a Two-Dimensional Human Motion Analysis System Using Digital Video Capture
(2009-08-14)A testing framework was developed to address system spatial and temporal performance characteristics in a two-dimensional (2D) human motion analysis system using commercially available digital video capture. The first ... -
The Spontaneous Combustion of Railway Ties and Asphalt Shingles
(2014-08-27)Many Low Carbon Fuels (LCFs) present unknown spontaneous combustion risks, which must be quantified before their use as fossil fuel replacements. Wood and coal spontaneous combustion is well understood; however, LCFs ... -
