Shipboard Deployment of a VHF OSCR System for Measuring Offshore Currents
Shipboard Deploymen VHF OSCR System Measuring Offshore Currents
2015/8/10
In July 1994, an OSCR unit was deployed aboard the R/V Columbus Iselin to explore the feasibility of obtaining offshore, vector surface currents from a single platform. The concept is straightforward....
Forecasting the Ocean's Optical Environment Using the BioCast System
Ocean's Optical Environment BioCast System
2015/7/20
The Bio-Optical Forecasting (BioCast) system is a model that provides the US Navy with short-term forecasts of the ocean's optical environment. The forecasts are required to support a broad spectrum o...
Power Flow Calculation Method of Large Shipboard Power System
power flow method node voltage method asynchronous motor transformer
2011/9/9
The effect of line voltage drop is considered larger on loads, especially on asynchronous motor, transformers and other non-linear load parameters in power system of large ships. A novel power flow me...
Nonequilibrium plankton community structures in an ecohydrodynamic model system
Nonequilibrium plankton community structures ecohydrodynamic model system
2009/11/16
Due to the local and global impacts of algae blooms and patchiness on water quality, carbon cycling and climate, models of plankton dynamics are of current interest. In this paper, the temporal and sp...
An application of system identification in the two-degree-freedom VIV experiments
system identification two-degree-freedom vortex-induced vibration
2011/9/13
Experiments on the two-degree-freedom vortex-induced vibration (VIV) of a flexibly-mounted, rigid, smooth cylinder were performed at MIT. The research reported here is an analysis of the cylinder’s tr...
