Tuning energy transport in solar thermal systems using nanostructured materials
(Massachusetts Institute of Technology, 2014)
Solar thermal energy conversion can harness the entire solar spectrum and theoretically achieve very high efficiencies while interfacing with thermal storage or back-up systems for dispatchable power generation. Nanostructured ...
Membraneless hydrogen bromine laminar flow battery for large-scale energy storage
(Massachusetts Institute of Technology, 2014)
Electrochemical energy storage systems have been considered for a range of potential large-scale energy storage applications. These applications vary widely, both in the order of magnitude of energy storage that is required ...
Closed-loop Reference Model adaptive control : with application to very flexible aircraft
(Massachusetts Institute of Technology, 2014)
One of the main features of adaptive systems is an oscillatory convergence that exacerbates with the speed of adaptation. Over the past two decades several attempts have been made to provide adaptive solutions with guaranteed ...
Extracting principles from biology for application to running robots
(Massachusetts Institute of Technology, 2014)
When millions of years of evolution suggest a particular design solution, we may be tempted to abandon traditional design methods and copy the biological example. However, biological solutions do not often translate directly ...
In vitro study of cancer cell extravasation in microfluidic platform
(Massachusetts Institute of Technology, 2014)
Cancer metastases arise from the cancer cells that disseminate from the primary tumor, intravasate into the vascular system and eventually transmigrate across the endothelium into to a secondary site through a process of ...
Technique and application for quantifying dynamic shoulder joint kinematics and glenohumeral joint contact patterns
(Massachusetts Institute of Technology, 2014)
The shoulder (glenohumeral) joint has the greatest range of motion of all human joints; as a result, it is particularly vulnerable to dislocation and injury. The ability to accurately measure dynamic in-vivo joint kinematics ...
Microjet based noise control of supersonic jets on carrier decks
(Massachusetts Institute of Technology, 2014)
The effectiveness of ground plane water microjet control on the noise generated by a supersonic, ideally expanded, Mach 1.5, impinging jet was determined. Using a converging-diverging nozzle with a design Mach number of ...
Assembling 3D MEMS structures by folding, aligning and latching 2D patterned films
(Massachusetts Institute of Technology, 2014)
The techniques used in the fabrication of micro-electro-mechanical systems (MEMS) were adopted from the integrated circuits (IC) industry and are mostly limited to patterning thin films on a flat substrate. As a consequence, ...
Asymptotically optimal path planning and surface reconstruction for inspection
(Massachusetts Institute of Technology, 2014)
Motivated by inspection applications for marine structures, this thesis develops algorithms to enable their autonomous inspection. Two essential parts of the inspection problem are (1) path planning and (2) surface ...
Learning from other perspectives : design and analysis of an in-place annotation system
(Massachusetts Institute of Technology, 2014)
I designed and studied NB, an in-place collaborative document annotation system targeting students reading lecture notes and draft textbooks. Serving as a discussion forum in the document margins, NB lets users ask and ...
