Mechanics of abrasive wear of elastomeric materials
(Massachusetts Institute of Technology, 2003)
Elastomeric materials are widely used as tire and sealing materials due to their ability to undergo large deformations and conform to the mating surface. However, their applications often result in repeated contact with ...
Thermodynamic and transport property modeling in super critical water
(Massachusetts Institute of Technology, 2005)
Supercritical water oxidation (SCWO) is a thermally-based, remediation and waste-treatment process that relies on unique property changes of water when water is heated and pressurized above its critical point. Above its ...
Retrieval of cloud-cleared atmospheric temperature profiles from hyperspectral infrared and microwave observations
(Massachusetts Institute of Technology, 2002)
This thesis addresses the problem of retrieving the temperature profile of the Earth's atmosphere from overhead infrared and microwave observations of spectral radiance in cloudy conditions. The contributions of the thesis ...
Memory consistency models for high performance distributed computing
(Massachusetts Institute of Technology, 2001)
This thesis develops a mathematical framework for specifying the consistency guarantees of high performance distributed shared memory multiprocessors. This framework is based on computations, which specify the operations ...
Stability of proteins within biodegradable microspheres
(Massachusetts Institute of Technology, 2000)
In the past decade, biodegradable polymers have become the materials of choice for a variety of biomaterials applications. In particular, poly(lactic-co-glycolic acid) (PLGA) microspheres have been extensively studied for ...
Constitutive modeling of Cu-Al-Ni shape memory alloys
(Massachusetts Institute of Technology, 2000)
Certain alloys can exist in multiple phases, which, in the context of solids, essentially mean multiple crystallographic structures. For example, at certain compositions, a Cu-Al-Ni alloy can exist as a cubic lattice ...
Simulation of ionospheric plasma heating experiments in the versatile toroidal facility
(Massachusetts Institute of Technology, 2001)
Remote sensing techniques employed to diagnose ionospheric modification experiments are intrinsically ambiguous, uncorrelated with "ground truth." To overcome this limitation, laboratory experiments are performed in the ...
The diurnal cycle of air pollution in the Kathmandu Valley, Nepal
(Massachusetts Institute of Technology, 2006)
This dissertation describes the most comprehensive study to date of the diurnal cycle of air pollution in the Kathmandu Valley, Nepal -- a bowl-shaped mountain valley of two million people with a growing air pollution ...
Automatic syllable detection for vowel landmarks
(Massachusetts Institute of Technology, 2000)
The biomechanics of knees at high flexion angles before and after Total Knee Arthroplasty
(Massachusetts Institute of Technology, 2004)
Total Knee Arthroplasty (TKA) was initially developed to alleviate pain in the case of severe arthritis of the knee. Restoration of knee motion has been an on going issue for the last decade. Contemporary TKAs appear to ...
