The pelvic bone is one of most stressed bones in the human body due to its essential task of weight-bearing of upper body. However, pelvic bone fractures usually occur as a result of high-rate impact loads, high cycle with low magnitude (e.g., stress fractures) or bone diseases such as pelvic...

Investigation of Potential Platforms for Low Frequency MEMS-based Piezoelectric Energy Harvesting
DownloadSpring 2015
MEMS based energy harvesters have recently been investigated for scavenging, otherwise useless, ambient vibration energy. Piezoelectric materials are fabricated on micro-devices to convert the mechanical vibration energy into electrical energy. The main focus for these harvesters is low frequency...

Investigation of the Double-Trap Intrinsic Kinetic Equation for the Oxygen Reduction Reaction and its implementation into a Membrane Electrode Assembly model.
DownloadFall 2012
A significant contributor to performance loss in polymer electrolyte fuel cells is the oxygen reduction reaction (ORR). A major challenge facing researchers is the development of a kinetic model that accurately accounts for ORR kinetics. Wang et al. proposed a kinetic model that assumes the ORR...

Investigation of the Tearing Mechanism of Bonded Soft Elastomers with Finite Interfacial Friction
DownloadFall 2015
The role of interfacial slippage on the deformation and stress fields near an interfacial crack are investigated in detail. First, the limiting extents of interfacial bonded friction, defined as the frictionless' andno-slip' cases, were modeled as hyperelastic elastostatic boundary value problems...

Investigation of the Velocity Field of Jets in Counter-Flow in the Vicinity of a Solid Wall
DownloadFall 2015
This study presents experimental investigations showing the mean and fluctuating velocity field of a three dimensional round jet in counter-flow located in the vicinity of a solid wall. The jet to counter-flow velocity ratios ranged from 2.5 to 25 and the jet Reynolds numbers were from 1,000 to...

Investigation of Ultrasonic Acoustic Standing Wave Separation of Particles in a Multi-wavelength Macro-scale Resonator
DownloadFall 2014
This thesis presents an investigation of macro-scale (>5mm) multi-wavelength acoustophoresis. This is a technique used for the filtration of micro-particles from the containing suspension. It uses the primary acoustic force generated by an ultrasonic acoustic pressure standing wave. Primary...
