Nondestructive evaluation of composite rods using ultrasonic wave propagation
(Massachusetts Institute of Technology, 2015)
Nondestructive Evaluation (NDE) is a branch of applied science that is concerned with assessing the properties and serviceability of materials and structures without causing collateral damage or depreciation. This study ...
Evaluation by simulation of an acoustic array composed of multiple autonomous vehicles
(Massachusetts Institute of Technology, 2015)
Ship-towed arrays have been integral to Navy combatant operations for many decades. The continual advancement of towed array technology has been continually driven by the need for high sensitivity, low self-noise, and ...
Mechanical characterization of lithium-ion battery micro components for development of homogenized and multilayer material models
(Massachusetts Institute of Technology, 2014)
The overall battery research of the Impact and Crashworthiness Laboratory (ICL) at MIT has been focused on understanding the battery's mechanical properties so that individual battery cells and battery packs can be ...
Integrating Model Based Engineering and trade space exploration into naval acquisitions
(Massachusetts Institute of Technology, 2016)
The Navy Acquisition force is faced with designing, procuring, and managing some of the most complex systems and technologies imagined. Balancing a shrinking and fickle budget environment with a program that has dynamic ...
An experimental study of the one Atmosphere Diving Suit (ADS) and data analysis of military diving
(Massachusetts Institute of Technology, 2016)
The Atmospheric Diving Suit (ADS) is a one-man submarine with moveable, humanlike appendages with internal pressure maintained at one atmosphere. This precludes the possibility of common diving related illnesses while ...
Risk-based treatment of uncertainty in trade space exploration : application via Monte Carlo simulation on a manned, mini-submersible model
(Massachusetts Institute of Technology, 2018)
In design, modeling and simulation are commonly used to answer questions of interest as it is both inefficient and expensive to physically build and evaluate numerous possibilities. Any modeling effort aims to build the ...
Material characterization of lithium ion batteries for crash safety
(Massachusetts Institute of Technology, 2015)
The safety of lithium-ion batteries is extremely important due to their widespread use in consumer products such as laptops and cell phones. Several cases of thermal runaway in lithium ion batteries that resulted in fires ...
Enabling tactical autonomy for unmanned surface vehicles in defensive swarm engagements
(Massachusetts Institute of Technology, 2018)
This research incorporates practical applications of marine vehicles with robotics control theory to reduce the vulnerability of allied assets to asymmetric warfare. This work utilizes distributed decentralized multi-objective ...
COLREGS-compliant autonomous collision avoidance using multi-objective optimization with interval programming
(Massachusetts Institute of Technology, 2014)
High contact density environments are becoming ubiquitous in autonomous marine vehicle (AMV) operations. Safely managing these environments and their mission greatly taxes platforms. AMV collisions will likely increase as ...
Combined tensile-compressive biaxial loading of Li-ion battery components
(Massachusetts Institute of Technology, 2018)
Lithium-ion batteries under a mechanical load can develop failures in the internal multi-layer structure. Due to the flammable materials required for construction, the safety of the battery has been in question since it ...
