List decoding of error-correcting codes
(Massachusetts Institute of Technology, 2001)
Error-correcting codes are combinatorial objects designed to cope with the problem of reliable transmission of information on a noisy channel. A fundamental algorithmic challenge in coding theory and practice is to efficiently ...
Coupled modes analysis of SRS backscattering, with Langmuir decay and possible cascadings
(Massachusetts Institute of Technology, 2002)
Recent experiments aimed at understanding stimulated Raman scattering (SRS) in ICF laser-plasma interactions, suggest that SRS is coupled to the Langmuir decay interaction (LDI). The effects of LDI on the saturation of the ...
Design, development and characterization of an integrated multispectral polarimetric sensor system
(Massachusetts Institute of Technology, 2001)
In this thesis, a new type of integrated imaging sensor is introduced to detect multispectral and polarimetric signatures in an infrared scene. The sensor is a stack consisting of an infrared detector array, and an array ...
Improving clinical decision making with natural language processing and machine learning
(Massachusetts Institute of Technology, 2017)
This thesis focused on two tasks of applying natural language processing (NLP) and machine learning to electronic health records (EHRs) to improve clinical decision making. The first task was to predict cardiac resynchronization ...
Apparent ridges for line drawing
(Massachusetts Institute of Technology, 2007)
Non-photorealistic line drawing depicts 3D shapes through the rendering of feature lines. A number of characterizations of relevant lines have been proposed but none of these definitions alone seem to capture all ...
Bridging the gap : an optimization-based framework for fast, simultaneous circuit & system design space exploration
(Massachusetts Institute of Technology, 2008)
Design of modern mixed signal integrated circuits is becoming increasingly difficult. Continued MOSFET scaling is approaching the global power dissipation limits while increasing transistor variability, thus requiring ...
Improving clinical risk-stratification tools : instance-transfer for selecting relevant training data
(Massachusetts Institute of Technology, 2014)
One of the primary problems in constructing risk-stratification models for medical applications is that the data are often noisy, incomplete, and suffer from high class-imbalance. This problem becomes more severe when the ...
Hybrid flow data center network architecture design and analysis
(Massachusetts Institute of Technology, 2017)
In this thesis, we propose a hybrid flow network architecture for future data center. The hybrid flow architecture has its origins in the early 1990s with studies on all-optical networks and fiber-optical computer networks. ...
Quantum error modelling and correction in long distance teleportation using singlet states
(Massachusetts Institute of Technology, 2002)
Fabrication of a planar optical add/drop channel filter in silicon oxynitride
(Massachusetts Institute of Technology, 2002)
