Temperature, heat flux, and velocity measurements in oscillating flows with pressure variations
(Massachusetts Institute of Technology, 1992)
Reconstructing 3D ocean temperature fields from real-time satellite and buoy surface measurements
(Massachusetts Institute of Technology, 2022-05)
Despite advancements in computational science, nonlinear geophysical processes still present important modeling challenges. Physical sensors (such as satellites, AUVs, or buoys) can collect data at specific points or ...
Scalable Synthesis of Solid-State Electrolytes Using Flame-Assisted Spray Pyrolysis
(Massachusetts Institute of Technology, 2022-05)
As the impacts of climate change become more apparent, demands for reliable and safe energy storage options are rapidly increasing. The decarbonization of several sectors that are responsible for large amounts of annual ...
Technoeconomic Analysis and Design of CO₂ Capture and Conversion Systems
(Massachusetts Institute of Technology, 2022-05)
Carbon capture and conversion technologies must become economically viable and scale to the gigaton level by 2050 to avoid the most serious effects of a climate crisis. Here we present a techno-economic analysis of two ...
Naval Submarine Maintenance: An Examination of Areas of Potential Availability Execution Risk
(Massachusetts Institute of Technology, 2022-05)
In the growing 'Great Power Competition' of the 21st century, the US Navy has faced near-peer competition that it has not experienced in several decades. This competition has ultimately resulted in increased operational ...
Control of oligonucleotide conformation on nanoparticle surfaces for nanoscale heat transfer study
(Massachusetts Institute of Technology, 2004)
Metal nanoparticles can be used as antennae covalently linked to biomolecules. External alternating magnetic field can turn on and off the biological activity of the molecules due to induction heating from the particles ...
Transcutaneous measurement of glucose using Raman spectroscopy
(Massachusetts Institute of Technology, 2004)
Transcutaneous glucose measurement would provide the ability to obtain frequent measurements without the pain and risk of infection associated with obtaining a blood sample and eliminates the need for reagents. Because of ...
A laser speckle based position sensing technique
(Massachusetts Institute of Technology, 2004)
This thesis presents the design and development of a novel laser-speckle-based position sensing technique. In our prototype implementation, a He-Ne laser beam is directed at the surface of an air-bearing spindle. An imaging ...
Solution of 2-D contact problems using a variational formulation with Lagrange multipliers
(Massachusetts Institute of Technology, 1982)
On the dynamics of wool spinning
(Massachusetts Institute of Technology, 1961)
