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 ...
Development of terahertz quantum-cascade lasers
(Massachusetts Institute of Technology, 2007)
The terahertz or the far-infrared frequency range of the electromagnetic spectrum ( ... ) has historically been technologically underdeveloped despite having many potential applications, primarily due to lack of suitable ...
Energy-efficient analog-to-digital conversion for ultra-wideband radio
(Massachusetts Institute of Technology, 2007)
In energy constrained signal processing and communication systems, a focus on the analog or digital circuits in isolation cannot achieve the minimum power consumption. Furthermore, in advanced technologies with significant ...
Tracking dynamic regions of texture and shape
(Massachusetts Institute of Technology, 2007)
The tracking of visual phenomena is a problem of fundamental importance in computer vision. Tracks are used in many contexts, including object recognition, classification, camera calibration, and scene understanding. ...
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 ...
FlowerPot : an anonymous BitTorrent client
(Massachusetts Institute of Technology, 2007)
This thesis presents and analyzes FlowerPot, an anonymous client for the BitTorrent file-sharing system. FlowerPot is peer-to-peer, providing scalability and making it difficult to attack with techniques like denial-of-service. ...
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, ...
Probabilistic network models for cardiovascular monitoring
(Massachusetts Institute of Technology, 2007)
While treating patients during their hospital stay, physicians must frequently take into consideration massive amounts of clinical data. This data can come in many forms, such as continuous blood pressure tracings, ...
Modeling medical devices for plug-and-play interoperability
(Massachusetts Institute of Technology, 2007)
One of the challenges faced by clinical engineers is to support the connectivity and interoperability of medical-electrical point-of-care devices. A system that could enable plug-and-play connectivity and interoperability ...
