Framed-Quadtree Path Planning for an Underwater Vehicle with the Task of Tracking a Moving Target
regular grid framed quadtree data structure algorithm efficiency
2011/9/9
An autonomous underwater vehicle (AUV) must use an algorithm to plan its path to distant, mobile offshore objects. Because of the uneven distribution of obstacles in the real world, the efficiency of ...
Research on global path planning based on ant colony optimization for AUV
autonomous underwater vehicle (AUV) path planning ant colony optimization path smoothing
2011/9/9
Path planning is an important issue for autonomous underwater vehicles (AUVs) traversing an unknown environment such as a sea floor, a jungle, or the outer celestial planets. For this paper, global pa...
Modulation of Gulf Stream Surface–Subsurface Frontal Separation by Path Curvature
Gulf Stream surface–subsurface frontal separation ubsurface-front path curvature
2009/1/7
Observations of surface–subsurface frontal separation have inconsistently demonstrated a relationship between surface–subsurface frontal separation and subsurface-front path curvature. An analytical m...
Meandering and Eddy Detachment According to a Simple（Looking）Path Equation
Eddy Detachment Simple（Looking）Path Equation Nonlinear meandering
2009/1/6
Nonlinear meandering and “pinching off” process are investigated by solving the path equation As shown by Pratt and Stern, this dimensioned equation determines the center line latitude l of a slowly-v...
Variations of Current Path, Velocity, and Volume Transport of the Kuroshio in Relation with the Large Meander
non-large-meander large-meander
2008/12/12
The variations of the Kuroshio Current path and their relations with current velocity, volume transport, and upstream position of the Kuroshio are examined using sea level data. After the long-time, n...
Inertial Boundary Layer with a Velocity Front：HOW the Bottom Slope Controls the Western Boundary Current Path
Inertial Boundary Layer Velocity Front Bottom Slope Western Boundary Current Path
2008/12/11
The western boundary current of the subtropical gyre flows on the upper continental slope and is controlled by the bottom topography; however, our theoretical understanding of how the path of the boun...
A Numerical Simulation of Wind Stress and Topographic Effects on the Kuroshio Current Path near Taiwan
Numerical Simulation Kuroshio Current Path Wind Stress
2008/12/10
A semispectral primitive equation model is used to study the effects of wind stress and bottom topography on the meandering of a jet over the continental margin. The jet is specified initially as a ge...
Effects of Stratification and Bottom Topography on the Kuroshio Path Variation South of Japan. Part I: Dependence of the Path Selection on Velocity
Stratification Bottom Topography Kuroshio Path Variation
2008/7/22
Numerical experiments are executed using a two-layer inflow–outflow ocean model with simplified geometry to investigate the effects of stratification and bottom topography on the path variation of the...
Kuroshio Path Variations South of Japan: Bimodality as a Self-Sustained Internal Oscillation
Kuroshio Path South of Japan Self-Sustained Internal Oscillation
2008/7/2
In the two decades following 1975, the Kuroshio path south of Japan was observed to oscillate interannually between a straight path state and a meandering state. This bimodal condition is in sharp con...
Effects of Stratification and Bottom Topography on the Kuroshio Path Variation South of Japan. Part II: Path Transitions in a Multiple Equilibrium Regime
Effects of Stratification Bottom Topography Kuroshio Path Variation
2008/6/30
The effects of stratification and bottom topography on the Kuroshio path transitions in a multiple equilibrium regime due to a short-term velocity increase are examined using a two-layer inflow–outflo...
