Rotation of a slender rod injected into a cylindrical constraint
(Massachusetts Institute of Technology, 2016)
We investigate the buckling of a slender elastic rod injected into a cylindrical constraint while undergoing axial rotation. Particular focus is given to extension of the helical buckling length. This problem is of particular ...
Development of experimental methods to measure osmosis-driven water flux and molecular transport across nanoporous graphene membranes
(Massachusetts Institute of Technology, 2015)
Graphene, an atomically thin planar lattice of sp2 bonded carbon atoms with high strength and impermeability, has drawn attention as a promising next generation high flux separation membrane. Molecular dynamics simulations ...
Coastal ocean variability off the coast of Taiwan in response to typhoon Morakot : river forcing, atmospheric forcing, and cold dome dynamics
(Massachusetts Institute of Technology, 2014)
The ocean is a complex, constantly changing, highly dynamical system. Prediction capabilities are constantly being improved in order to better understand and forecast ocean properties for applications in science, industry, ...
Using predictive analytics to address risk in complex supply chains
(Massachusetts Institute of Technology, 2018)
Li & Fung (LF) is a global supply chain manager for consumer product brands and retailers. Worldwide, LF contracts with over 13,000 factories. Frequently, these factories experience incidents, which are internally defined ...
Elucidating efficiency losses in cuprous oxide (Cu₂O) photovoltaics and identifying strategies for efficiency improvement
(Massachusetts Institute of Technology, 2013)
In this thesis, I fabricated and characterized a series of thin-film cuprous oxide (Cu₂O) photovoltaic devices. I constructed several different device designs, using sputtered and electrochemically deposited Cu₂O. ...
Surface structural changes of perovskite oxides during oxygen evolution in alkaline electrolyte
(Massachusetts Institute of Technology, 2013)
Perovskite oxides such Ba0.5Sr0.5Co0.8Fe0.8O3-6 (BSCF82) are among the most active catalysts for the oxygen evolution reaction (OER) in alkaline solution reported to date. In this work it is shown via high resolution ...
Reducing reworkable discrepancies through standard work for writing inspection instructions and data distribution
(Massachusetts Institute of Technology, 2013)
Each aircraft on the final assembly line inevitably has minor build errors and deviations from the intended design. Errors, like these, that can be corrected on the line are called reworkable discrepancies. Because hundreds ...
Separate effects of surface roughness, wettability and porosity on boiling heat transfer and critical heat flux and optimization of boiling surfaces
(Massachusetts Institute of Technology, 2012)
The separate effects of surface wettability, porosity, and roughness on critical heat flux (CHF) and heat transfer coefficient (HTC) were examined using carefully-engineered surfaces. All test surfaces were prepared on ...
Nuclear tanker producing liquid fuels from air and water
(Massachusetts Institute of Technology, 2011)
Emerging technologies in CO₂ air capture, high temperature electrolysis, microchannel catalytic conversion, and Generation IV reactor plant systems have the potential to create a shipboard liquid fuel production system ...
Tool selection and kitting : technical and organizational issues
(Massachusetts Institute of Technology, 2013)
Boeing South Carolina builds the Boeing 787 Dreamliner, the world's first composite-skinned wide-body jet. This new manufacturing facility is evolving to meet the demands of building this complex aircraft. One of the ...
