Breakdown Anodization (BDA) for hierarchical structures of titanium oxide
(Massachusetts Institute of Technology, 2013)
Breakdown Anodization (BDA) of titanium dioxide is a very promising, fast fabrication method to construct micro-scale and nano-scale structures on titanium surfaces. This method uses environmentally friendly electrolytes, ...
Organization and differentiation of stem cells on delivery scaffold for retinal tissue engineering
(Massachusetts Institute of Technology, 2011)
Retinal degenerative diseases, including retinitis pigmentosa and age-related macular degeneration, affect more than ten million people in the US. Currently, there is no proven visually beneficial treatment for these types ...
Optimization of central receiver concentrated solar thermal : site selection, heliostat layout & canting
(Massachusetts Institute of Technology, 2011)
In this thesis, two new models are introduced for the purposes of (i) locating sites in hillside terrain suitable for central receiver solar thermal plants and (ii) optimization of heliostat field layouts for any terrain. ...
A modified experts algorithm : using correlation to speed convergence with very large sets of experts
(Massachusetts Institute of Technology, 2006)
This paper discusses a modification to the Exploration-Exploitation Experts algorithm - (EEE). The EEE is a generalization of the standard experts algorithm which is designed for use in reactive environments. In these ...
Column separation and waterhammer in binary mixture
(Massachusetts Institute of Technology, 1983)
Insurge pressure response and heat transfer for PWR pressurizer
(Massachusetts Institute of Technology, 1983)
On learning from videos/
(Massachusetts Institute of Technology, 2018)
The robot phone disassembly task is difficult in many ways: It has requirements on high precision, high speed, and should be general to all types of cell phones. Previous works on robot learning from demonstration are ...
Stability-constrained design for low voltage DC microgrids
(Massachusetts Institute of Technology, 2018)
Microgrids are a promising solution to reducing the energy access gap. However, microgrids are inherently fragile systems as they are not globally stable. This thesis considers two voltage instabilities that can arise in ...
A study of node-based finite elements for the solution of the time-harmonic Maxwell equations
(Massachusetts Institute of Technology, 2017)
Classical node-based finite elements are well-known to cause difficulties in the solution of the Maxwell equations. These difficulties are discussed and investigated by means of numerical examples in this thesis. Time-harmonic ...
Tactile measurement with a GelSight sensor
(Massachusetts Institute of Technology, 2014)
This thesis introduces a method of measuring contact force with GelSight. GelSight is an optical-based tactile sensor that uses a piece of coated elastomer as the contact medium. A camera records the distortion of the ...
