The Active Wave-front Sampling based 3D endoscope
(Massachusetts Institute of Technology, 2007)
This thesis investigates the potential of Active Wave-front Sampling (AWS) for real time quantified 3D endoscopy. AWS is a technique by which phase information from an aperture area of a lens is obtained by sampling ...
Analysis and validation of an artifact resistant design for oxygen saturation measurement using photo pletyhsmographic ring sensors
(Massachusetts Institute of Technology, 2004)
Recent advances in continuous noninvasive health monitoring technologies provide clinicians and researchers with a previously unrealistic opportunity for closely tracking the developments and treatments of various pathologies ...
Cooperative tracking for persistent littoral undersea surveillance
(Massachusetts Institute of Technology, 2007)
The US Navy has identified a need for an autonomous, persistent, forward deployed system to Detect, Classify, and Locate submarines. In this context, we investigate a novel method for multiple sensor platforms acting ...
Structural and thermal design of a dual-rotor constant-frequency, variable-speed generator
(Massachusetts Institute of Technology, 2003)
The mechanical design of a novel generator type is considered. This generator is intended to efficiently, reliably and cheaply convert a variable shaft-speed input into a constant electrical frequency output for application ...
Modeling magnetic core loss for sinusoidal waveforms
(Massachusetts Institute of Technology, 2008)
Among the challenging unsolved technical problems that have plagued the minds of scientist and engineers throughout the 20th and 21st century is the development of a quantifiable model to accurately estimate or explain ...
On the design of a precision machine for closed-loop performance
(Massachusetts Institute of Technology, 2002)
Cuff-less continuous monitoring of beat-to-beat blood pressure using a Kalman filter and sensor fusion
(Massachusetts Institute of Technology, 2000)
A two-phase spherical electric machine for generating rotating uniform magnetic fields
(Massachusetts Institute of Technology, 2007)
This thesis describes the design and construction of a novel two-phase spherical electric machine that generates rotating uniform magnetic fields, known as a fluxball machine. Alternative methods for producing uniform ...
Control primitives for fast helicopter maneuvers
(Massachusetts Institute of Technology, 2006)
In this paper, we introduce a framework for learning aggressive maneuvers using dynamic movement primitives (DMP) for helicopters. Our ultimate goal is to combine these DMPs to generate new primitives and demonstrate them ...
