Evolving language among agents
(Massachusetts Institute of Technology, 1999)
Capacity provisioning, failure recovery and throughput analysis for low earth orbit satellite constellations
(Massachusetts Institute of Technology, 2002)
We investigate the capacity needed to build a restorable satellite network and design routing schemes to achieve high throughput. Specifically, the first part of this thesis considers the link capacity requirement for a ...
High-speed modulation of resonant CMOS photonic modulators in deep-submicron bulk-CMOS
(Massachusetts Institute of Technology, 2009)
Processor manufacturers have turned to parallelism to continue to improve processor performance, and the bandwidth demands of these systems have risen. Silicon photonics can lower the energy-per-bit of core-to-core and ...
Faster generation of random spanning trees
(Massachusetts Institute of Technology, 2009)
In this thesis, we set forth a new algorithm for generating approximately uniformly random spanning trees in undirected graphs. We show how to sample from a distribution that is within a multiplicative (1+6) of uniform in ...
An optical data receiver for integrated photonic interconnects
(Massachusetts Institute of Technology, 2009)
The throughput bounds of traditional interconnect networks in microprocessors are being pushed to their limits. In past single-core processors, the number of long global wires constituted only a small fraction of the total. ...
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 ...
Quantum error modelling and correction in long distance teleportation using singlet states
(Massachusetts Institute of Technology, 2002)
