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 ...
Automatic syllable detection for vowel landmarks
(Massachusetts Institute of Technology, 2000)
Industrial applications of photonuclear resonance excitation
(Massachusetts Institute of Technology, 2000)
Photonuclear resonance excitation refers to a variety of photonuclear interaction processes that lead to the excitation of a nucleus from some initial state to a higher energy nuclear state. Typical excited nuclear state ...
Sociable machines : expressive social exchange between humans and robots
(Massachusetts Institute of Technology, 2000)
Sociable humanoid robots are natural and intuitive for people to communicate with and to teach. We present recent advances in building an autonomous humanoid robot, Kismet, that can engage humans in expressive social ...
Cardiac tissue engineering : bioreactor cultivation parameters
(Massachusetts Institute of Technology, 2000)
Tissue engineering may be useful in fighting heart disease since it offers the possibility of creating functional tissue equivalents for scientific studies and tissue repair. In the present work, we examined how variations ...
Large scale oceanic circulation and fluxes of freshwater, heat, nutrients and oxygen
(Massachusetts Institute of Technology, 2000)
A new, global inversion is used to estimate the large scale oceanic circulation based on the World Ocean Circulation Experiment and Java Australia Dynamic Experiment hydrographic data. A linear inverse "box" model is used ...
An estimation-theoretic technique for motion-compensated synthetic-aperture array imaging
(Massachusetts Institute of Technology, 2000)
Synthetic-Aperture Radar (SAR) is an imaging technique that achieves high azimuth resolution by using coherent processing to exploit the relative motion between an airborne or spaceborne radar antenna and the imaged target ...
A spectroscopic and electrochemical study of chlorotitanates in molten salt media
(Massachusetts Institute of Technology, 2000)
Ultra-high purity titanium is used as a barrier metal in integrated circuitry. Metallothermic reduction does not produce titanium sufficiently pure for micro-electronics applications so electro refining of the metal in a ...
A dual/high-voltage automotive electrical power system with superior transient performance
(Massachusetts Institute of Technology, 2000)
Today's automotive electrical power system is based on an engine-driven alternator regulated at 14 V which charges a 12 V battery and delivers power to the loads. Installed electrical power is growing rapidly with model ...
