Design of the All-Electric Ship: Focus on Integrated Power System Coupled to Hydrodynamics
(Massachusetts Institute of Technology. Sea Grant College Program, 2008)
We present a detailed model of the integrated power system coupled to hydrodynamics that allows us to study global sensitivities in the All-Electric Ship. A novel element of our formulation is the stochastic modeling of ...
Linearized Hovering Control With One or More Azimuthing Thrusters
(Massachusetts Institute of Technology. Sea Grant College Program, 2007)
We propose a simple method of control system design for marine vehicles with one or more azimuthing propulsors, and specifically for the case where the speed of the actuator is on the same time scale as the plant dynamic ...
Seeking Didemnum on Georges Bank
(Massachusetts Institute of Technology. Sea Grant College Program, 2009)
Preliminary report of the MITSG Autonomous Underwater Vehicle cruise to Georges Bank on July 8-21 of 2008. The purpose of this cruise was to test the efficacy of an acoustic sensor in identifying the distribution of an ...
Geographical Analysis of Ballast Water Data and Potential Threats of Invasive Species for the North Eastern United States
(Massachusetts Institute of Technology. Sea Grant College Program, 2008-12)
The globalization of consumer goods and natural resources has led to an unintentional increase in exchanges of native biota (Bright 1999, Barbier and Shogren 2004, Perrings et al. 2005). Organisms that were once constrained ...
System-level Modeling of Cooling Networks in All Electric Ships
(Massachusetts Institute of Technology. Sea Grant College Program, 2014)
A Thermal management simulation tool is required to rapidly and accurately evaluates and mitigates the adverse effects of increased heat loads in the initial stages of design in all electric ships. By reducing the dimension ...
Parametric Optimization of S-type Cables
(Massachusetts Institute of Technology. Sea Grant College Program, 2014)
We formulated an S-curve parameterization for re-routing a cable path for a given offset displacement. In our approach we assume the cable path to follow a tangent hyperbolic curve. In our formulation, after taking the ...
