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. ...
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 ...
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)
Coding in the fusiform face area of the human brain
(Massachusetts Institute of Technology, 2003)
Synchronization on nulticore architectures
(Massachusetts Institute of Technology, 2014)
The rise of multicore computing has made synchronization necessary to overcome the challenge of sharing data between multiple threads. Locks are critical synchronization primitives for maintaining data integrity and ...
