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 ...
Shipboard condition based maintenance and integrated power system initiatives
(Massachusetts Institute of Technology, 2011)
With the U.S. Navy's continued focus on developing and implementing a robust integrated power system aboard future combatants, there has been an ever increasing effort to guarantee an electrical distribution system that ...
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 ...
Object localization and identification for autonomous operation of surface marine vehicles
(Massachusetts Institute of Technology, 2016)
A method for autonomous navigation of surface marine vehicles is developed A camera video stream is utilized as input to achieve object localization and identification by application of state-of-the-art Machine Learning ...
DC to DC power conversion module for the all-electric ship
(Massachusetts Institute of Technology, 2011)
The MIT end to end electric ship model is being developed to study competing electric ship designs. This project produced a model of a Power Conversion Module (PCM)- 4, DC-to-DC converter which interfaces with the MIT ...
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 ...
An efficient drive, sensing, and actuation system using PZT stack actuator cells
(Massachusetts Institute of Technology, 2012)
The PZT cellular actuator developed in the MIT d'Arbeloff Laboratory utilizes small-strain, high-force PZT stack actuators in a mechanical flexure system to produce a larger-strain, lower-force actuator useful in robotic ...
Autonomous adaptation and collaboration of unmanned vehicles for tracking submerged contacts
(Massachusetts Institute of Technology, 2012)
Autonomous operations are vital to future naval operations. Unmanned systems, including autonomous underwater vehicles (AUVs) and autonomous surface vehicles (ASVs), are anticipated to play a key role for critical tasks ...
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 ...
