Multi-channel blind system identification using the Laguerre expansion for characterization of circulatory hemodynamics
(Massachusetts Institute of Technology, 2004)
A new tool for real-time characterization of both systemic and local circulatory hemodynamics has been developed. Given two peripheral circulatory waveform measurements this new signal-processing algorithm generates two ...
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 ...
A pseudo-polynomial time O(log² n)-approximation algorithm for art gallery problems
(Massachusetts Institute of Technology, 2006)
In this thesis, we give a pseudo-polynomial time O(log² n)-approximation algorithm for a variant of the art gallery problem the point-guard problem. The point-guard problem involves finding the minimum number of points and ...
Optimal control with structure constraints and its application to the design of passive mechanical systems
(Massachusetts Institute of Technology, 2002)
Structured control (static output feedback, reduced-order control, and decentralized feedback) is one of the most important open problems in control theory and practice. In this thesis, various techniques for synthesis of ...
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 ...
Design and signal processing of finger photo plethysmograph ring sensors for reduced motion artifact and circulation interference
(Massachusetts Institute of Technology, 2002)
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 ...
Cuff-less continuous monitoring of beat-to-beat blood pressure using a Kalman filter and sensor fusion
(Massachusetts Institute of Technology, 2000)
On the design of a precision machine for closed-loop performance
(Massachusetts Institute of Technology, 2002)
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 ...
