Achilles Assistance Device as a Passive Ankle Foot Orthosis for Achilles Tendon Injuries

Creator:: Gonnerman, Evan J.
Abstract:: An Achilles tendon injury can be devastating. Surgical methods to bring the muscle to full strength are not always available. Proposed is an ankle foot orthosis (AFO) that is entirely passive (does not add energy to the system) and uses the mechanical advantages provided by the walking gait of a...

Evaluation of total hip arthroplasty research in the US and Europe

Creator:: Simmons, Marcy J.
Abstract:: Background: Hip replacements are considered routine operations which improve the quality of life in patients by reducing pain and restoring function. There are many variations in prostheses with varying benefits and disadvantages. Methods: Literature from the United States and Europe was collected on total hip replacements between 2001 and the...

Functional imaging reveals modest strain concentrations associated with implant micromotion using modified BAK interbody cages

Creator:: Berry, Daniel J.
Abstract:: Interbody fusion cages are increasingly used in the treatment of spinal disease and injury in order to stabilize movement and promote arthrodesis of the vertebral bodies, but the micro-mechanics of the interaction between the cage and the adjacent host bone is not fully understood. This information has bearing on post-surgical...

Influence of subset size, shape and orientation on texture based digital image correlation

Creator:: Cui, Jianqing
Abstract:: Digital Image Correlation(DIC) is one of full-field strain measurement techniques devel- oped in recent decades, which has been well-demonstrated to conduct the mechanical properties study of solid materials, by collecting data using digital cameras. X-ray to- mography(CT) imaging helps the correlation techniques expanded to three dimensional investigation of materials, known...

Turbulent Heat Transfer of Supercritical Carbon Dioxide in the Proximity of the Pseudo-Critical Point with Non-Uniform Heat Flux Boundary Conditions

Creator:: Jajja, Saad A.
Abstract:: Seven decades of supercritical heat transfer research have not seen an attempt to characterize turbulent thermal transport in internal flows subject to asymmetric heating. Existing heat transfer models therefore do not account for phenomena that dictates thermal transport, in the proximity of the pseudo-critical point, for non-uniform heating. Additionally, past...

A study of adiabatic and diabatic flow boiling in parallel microchannels and fractal-like branching microchannels

Creator:: Daniels, Brian J.
Abstract:: A one-dimensional numerical model has been developed to study diabatic and adiabatic flow boiling in microchannels. This model accounts for developing flow effects and variable property effects. The model uses correlations for void fraction and two-phase multipliers found in the literature. The model has been used to study the performance...

A study of the characteristics of oscillatory surface instabilities leading to droplet formation

Creator:: Daniels, Brian J.
Abstract:: The characteristics of the free surface in an orifice driven by a periodic forcing function have been studied both theoretically and experimentally. In the theoretical study, two wall boundary condition cases were examined: 1) the radial velocity at the wall of the orifice is zero; and 2) the axial velocity...

Development and validation of acoustic measurement techniques for void fraction in concentric annular geometries

Creator:: Tost, Brian C.
Abstract:: This work investigates the acoustic velocity of gas-liquid mixtures in vertical, co-current flow in a concentric annulus. Acoustic velocity shows promise as a detection parameter for the presence and amount of gas in a liquid flow because of its high sensitivity to gas void fraction in a gas-liquid mixture. However,...

The Feasibility of Process Intensification of the Water-Gas Shift Reaction using Differential Temperature Microreactors

Creator:: Tolley, Thomas E.
Abstract:: Hydrogen is an increasingly attractive low-carbon energy carrier for a variety of stationary and mobile applications. Currently, the vast majority of hydrogen in the United States is produced via the energy intensive steam reforming of natural gas. The cost and carbon emissions associated with hydrogen production can be reduced by...

Numerical and Experimental Evaluation of Membrane Based Energy Recovery Ventilator Performance with an Internal Support Structure

Creator:: Armatis, Paul D.
Abstract:: Large amounts of energy are wasted when conditioned air in buildings is exhausted to meet ventilation requirements. There are several technologies to recover some of this energy, including the recent development of membrane based energy recovery ventilators (ERVs). ERVs exchange sensible heat and moisture between incoming fresh and outgoing exhaust...
