Development of intersubband terahertz lasers using multiple quantum well structures
(Massachusetts Institute of Technology, 1998)
This thesis describes an experimental and theoretical effort in developing intersubband THz lasers using multiple-quantum-well structures. Scarcity of compact solid state sources in this frequency range, and to demonstrate ...
Utility assessment based on individualized patient perspectives
(Massachusetts Institute of Technology, 1998)
The feasibility of using the terminology of the individual patient to capture and express the individual's particular, perhaps unique, value system for healthiness is explored as a means to evaluate the quality of life. ...
Impact of IT-enabled organizational change on firm performance : an event study
(Massachusetts Institute of Technology, 2002)
Past event-studies on the impact of Information Technology (IT) on organizations have focused on the different types of IT initiatives from various perspectives, for e.g., an organizational perspective (joint venture, ...
Venture capital and innovation in information technology : evaluation of the French public policy
(Massachusetts Institute of Technology, 1999)
Today, there are hundreds of new ventures in Silicon valley, and on the route 128 in Massachusetts that were created by French people. However, in France, innovation in high-technology has stabilized and did not significantly ...
Inferential measurement of aerodynamic forces for use in wing divergence analysis
(Massachusetts Institute of Technology, 1959)
Dispersion of water sprays in a transverse air jet and the aging of spray nozzles
(Massachusetts Institute of Technology, 1999)
This thesis explores spray cooling methods used in the manufacturing process of glass fibers. At the onset of the manufacturing process glass fibers are extruded from a pool of molten glass through an array of holes in a ...
Scalable manufacturing of hierarchical nanostructures for thermal management
(Massachusetts Institute of Technology, 2012)
The focus of this thesis is a new simple and scalable process to make surface coatings that have multiple length scales, or hierarchical features. Typically, the formation of hierarchical structures involves multiple steps ...
How local can government go? : lessons from fiscal decentralization in Uganda
(Massachusetts Institute of Technology, 1999)
Revenue collection in the Kibaale District in Uganda, specifically the graduated tax, has improved at the sub-county level of local government under Uganda's ambitious decentralization process. Improved collection is ...
Characterizing and recognizing spoken corrections in human-computer dialog
(Massachusetts Institute of Technology, 1998)
Miscommunication in human-computer spoken language systems is unavoidable. Recognition failures on the part of the system necessitate frequent correction attempts by the user. Unfortunately and counterintuitively, users' ...
Variation reduction of a closed-loop precision ceramic micromachining process
(Massachusetts Institute of Technology, 1996)
This report details the investigation of the micromachining of a TiC.A1203 ceramic using a closed-loop lapping process. Currently the micromachining process laps a ceramic bar with only a priori flatness adjustment. Bar ...
