Velocity vectors for features of sequential oceanographic images

IEEE Transactions on Geoscience and Remote Sensing, 1998
This paper investigates a fundamental problem of determining the position, orientation, and velocity field of the Gulf Stream in time-varying imagery. The authors propose an approximation method to characterize the deformation of these image motions for the purpose of estimating the velocity field of these images.

The Discovery of the Vector Representation of Moments and Angular Velocity

Archive for History of Exact Sciences, 2002
The author studies the discovery of vector representation of moments and angular velocity. In this deep study chapters are devoted to: Frisi and the parallelogram of infinitesimal rotation (1759); Euler and the vector representation of moments of forces (1780); Laplace and the invariable plane (1798); Prony and the diffusion of Euler's formula (1800 ...

P-Vector Spirals and Determination of Absolute Velocities

Journal of Oceanography, 2000
A simple method to invert the absolute geostrophic velocity on potential-density surfaces is developed based on McDougall’s (1988) conservation statements on potential-density surfaces and Chu’s (1995) and McDougall’s (1995) P-vector concept. This method has a capability to handle a system with diapycnal velocities and non-coincidence of potential ...
