Design and fabrication of granular materials for surface acoustic waves
(Massachusetts Institute of Technology, 2015)
Granular materials with structural discreteness and periodicity can lead to novel propagation behaviors of mechanical waves. Acoustic studies of granular media typically involve macroscopic particles whereas contact-based ...
Design of an Autonomous Underwater Vehicle (AUV) charging system for underway, underwater recharging
(Massachusetts Institute of Technology, 2014)
Modern robotics have enabled the rapid proliferation of Autonomous Underwater Vehicles (AUVs) throughout the marine environment. As autonomy algorithms increase in robustness, complexity, and reliability, so too does the ...
Design of an instrumented multifunctional foot for application to a heavy duty mobile robot manufacturing system
(Massachusetts Institute of Technology, 2008)
The design of a multifunctional foot for application to a mobile robotic system for heavy duty manufacturing is presented. The requirements for a target manufacturing task are presented and translated into requirements for ...
Analysis of system wide distortion in an integrated power system utilizing a high voltage DC bus and silicon carbide power devices
(Massachusetts Institute of Technology, 2007)
This research investigates the distortion on the electrical distribution system for a high voltage DC Integrated Power System (IPS). The analysis was concentrated on the power supplied to a propulsion motor driven by an ...
