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. ...
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' ...
A database of computer attacks for the evaluation of intrusion detection systems
(Massachusetts Institute of Technology, 1999)
The 1998 DARPA intrusion detection evaluation created the first standard corpus for evaluating computer intrusion detection systems. This corpus was designed to evaluate both false alarm rates and detection rates of intrusion ...
A single-pass grid-based algorithm for clustering big data on spatial databases
(Massachusetts Institute of Technology, 2017)
The problem of clustering multi-dimensional data has been well researched in the scientific community. It is a problem with wide scope and applications. With the rapid growth of very large databases, traditional clustering ...
Natural communication with robots
(Massachusetts Institute of Technology, 1994)
Setting language parameters using genetic algorithms
(Massachusetts Institute of Technology, 1992)
Dynamic nanometer alignment for nanofabrication and metrology
(Massachusetts Institute of Technology, 1998)
Future generations of IC fabrication depend in part on continued improvements in lithography. To meet the lithographic challenges posed by 25- nm lithography, a novel through-the-mask, interferometric imaging alignment ...
A symbolic analysis of relay and switching circuits
(Massachusetts Institute of Technology, 1940)
Squadbox : a tool to combat email harassment using friendsourced moderation
(Massachusetts Institute of Technology, 2017)
Online harassment is both a social and technical problem, and has yet to be successfully solved. In order to better understand the issue and the challenges surrounding it, we conducted interviews with eighteen recipients ...
