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 ...
Query-by-example for motion capture data
(Massachusetts Institute of Technology, 2007)
Motion capture datasets are employed widely in animation research and industry, however there currently exists no efficient way to index and search this data for diversified use. Motion clips are generally searched by ...
Robotic compensation of cerebellar ataxia
(Massachusetts Institute of Technology, 2007)
The cerebellum is believed to play a role in dynamic compensation in the human motor control system. When it is damaged, subjects make clumsy movements with reduced acceleration, increased overshoot, and swerving in ...
HQ replication
(Massachusetts Institute of Technology, 2007)
There are currently two approaches to providing Byzantine-fault-tolerant state machine replication: an agreement-based approach, e.g., BFT, that uses communication between replicas to agree on a proposed ordering of requests, ...
Design of a Very High Frequency dc-dc boost converter
(Massachusetts Institute of Technology, 2007)
Passive component volume is a perennial concern in power conversion. With new circuit architectures operating at extreme high frequencies it becomes possible to miniaturize the passive components needed for a power converter, ...
Subspace polynomials and list decoding of Reed-Solomon codes
(Massachusetts Institute of Technology, 2007)
We show combinatorial limitations on efficient list decoding of Reed-Solomon codes beyond the Johnson and Guruswami-Sudan bounds [Joh62, Joh63, GS99]. In particular, we show that for any ... , there exist arbitrarily large ...
Fabrication of a luminescent solar concentrator that minimizes self-absorption losses using inter-chromophore energy transfer
(Massachusetts Institute of Technology, 2007)
The projected need for carbon-free power during this century is immense. Solar power offers the largest resource base to supply this need, but in light of recent silicon shortages, it is an open question whether silicon ...
The application of network coding to multicast routing in wireless networks
(Massachusetts Institute of Technology, 2007)
This thesis considers the application of network coding and opportunistic routing to improve the performance of multicast flows in wireless networks. Network coding allows routers to randomly mix packets before forwarding ...
Scoop : an adaptive indexing scheme for stored data in sensor networks
(Massachusetts Institute of Technology, 2007)
We present the design of Scoop, a system that is designed to efficiently store and query relational data collected by nodes in a bandwidth-constrained sensor network. Sensor networks allow remote environments to be monitored ...
Tavarua : a mobile telemedicine system using WWAN striping
(Massachusetts Institute of Technology, 2007)
Tavarua is a platform designed to support mobile telemedicine systems over wireless wide area networks, WWANs. It utilizes network striping and other complementary techniques to send uni-directional near real time video ...
