Light and nutrient control of photosynthesis in natural phytoplankton populations from the Chukchi and Beaufort seas, Arctic Ocean
Light nutrient control of photosynthesis
2014/4/2
During the 2010–2011 ‘Impacts of Climate Change on the EcoSystems and Chemistry of the Arctic Pacific
Environment’ project, we measured photosynthetic parameters in natural Arctic phytoplankton assem...
Hydraulie Control and Flow Separation in a Multi-Layered Fluid with Applications to the Vema Channel
Hydraulie Control Multi-Layered Fluid Flow Separation
2009/2/5
Observations from a recent field experiment in the Vema Channel are briefly described. These show a remarkable change in the configuration of isopycnal surfaces within the channel and the development ...
Geostrophic Control of Fluctuating Barotropic Flow through Straits
Geostrophic Control Fluctuating Barotropic Flow Fluctuating Barotropic Flow
2009/1/20
A simple model in which the cross-strait sea surface slope is geostrophically balanced and the along-strait slope is balanced by acceleration and friction, is shown to be supported by the results of B...
Multilayer Hydraulic Control with Application to the Alboran Sea Circulation
Multilayer Hydraulic Control Alboran Sea Circulation
2009/1/15
The flow of a single layer of fluid along a channel of variable dimensions is hydraulically controlled when long gravity waves can no longer propagate upstream at the cross-section of minimum area. Fo...
Hydraulic Control of Sill Flow with Bottom Friction
Hydraulic Control Sill Flow Bottom Friction
2009/1/13
The hydraulics of strait and sill flow with friction is examined using a reduced gravity model. It is shown that friction moves the critical (or control) point from the sill to a location downstream. ...
Hydraulic Control of Flows with Nonuniform Potential Vorticity
Hydraulic Control Flows Nonuniform Potential Vorticity
2009/1/9
The hydraulics of flow contained in a channel and having nonuniform potential vorticity is considered from a general standpoint. The channel cross section is rectangular and the potential vorticity is...
A nonlinear one-layer model is considered in order to describe the way that water with a relative vorticity intrudes into an otherwise stagnant channel. The channel has a uniform depth (D) and width (...
Optimal control of deteriorating production inventory systems
Inventory systems deterioration optimal control Pontryagin maximum principle target
2009/1/8
We are using in this paper an optimal control approach to determine the optimal
production rate in a production inventory system where items are subject
to deterioration. Necessary and sufficient op...
An Optimal-Control/Adjoint-Equations Approach to Studying the Oceanic General Circulation
Optimal-Control/Adjoint-Equations oceanographic observations Oceanic General Circulation
2009/1/4
An efficient procedure is presented for analyzing oceanographic observations with the aid of a general circulation model. Poorly known model parameters, such as eddy-mixing coefficients, surface forci...
Geometrical Control of the Inertial Recirculation
Inertial Recirculation free solution quasi-geostrophic equation
2008/12/30
In this paper we discuss the conditions under which a free solution of the steady, one-layer, quasi-geostrophic equation on a β-plane is realized in the inviscid limit. We restrict attention to the ca...
The Control of Fjord Circulation by Fortnightly Modulation of Tidal Mixing Processes
Fjord Circulation Fortnightly Modulation Tidal Mixing Processes
2008/12/19
Tidal processes that control basin–ocean water exchange across a sill, namely, the fortnightly modulation of mixing intensity associated with the spring-neap tidal cycle, are examined. The study proce...
Advanced FNN control of mini underwater vehicles
College of Shipbuilding Engineering, Harbin Engineering University
2011/9/14
Fuzzy neural networks (FNN) based on Gaussian membership functions can effectively control the motion of underwater vehicles. However, their operating processes and training algorithms are complicated...
Modeling a high output marine steam generator feedwater control system which uses parallel turbine-driven feed pumps
feedwater control steam generator modeling feed pump turbine
2011/9/14
Parallel turbine-driven feedwater pumps are needed when ships travel at high speed. In order to study marine steam generator feedwater control systems which use parallel turbine-driven feed pumps,a ma...
An analytic solution is presented for the steady-state depth-averaged western boundary current flowing over the continental slope by combining three highly idealized models: the Stommel model, the Mun...
Boundary Layer Control of Buoyant Coastal Currents and the Establishment of a Shelfbreak Front
Boundary Layer Control of Buoyant Coastal Currents and the Establishment of a Shelfbreak Front
2008/7/4
The bottom boundary layer exerts a powerful control over buoyant coastal currents that contact the bottom, providing a mechanism for trapping density fronts along isobaths. Recent observations suggest...
