VORONOI DIAGRAMS OF MOVING POINTS IN THE PLANE

International Journal of Computational Geometry & Applications, 1990
In this paper, we consider the dynamic Voronoi diagram problem. In this problem, a given set of planar points are moving and our objective is to find the Voronoi diagram of these moving points at any time t. A preprocessing algorithm and a query processing algorithm are presented in this paper. Assume that the points are in k-motion, and it takes O(k)

Stokes problems for moving half-planes

Journal of Fluid Mechanics, 1995
New exact solutions of the Navier–Stokes equations are obtained for the unbounded and bounded oscillatory and impulsive tangential edgewise motion of touching half-infinite plates in their own plane. In contrast to Stokes classical solutions for the harmonic and impulsive motion of an infinite plane wall, where the solutions are separable or have a ...

The visual ambiguity of a moving plane

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1984
Abstract It is shown that the optic flow field arising from motion relative to a visually textured plane may be characterized by eight parameters that depend on the observer’s linear and angular velocity and the coordinate vector of the plane.

Voronoi diagrams of moving points in the plane

1992
Consider a set of n points in the Euclidean plane each of which is continuously moving along a given trajectory. At each instant in time, the points define a Voronoi diagram. As the points move, the Voronoi diagram changes continuously, but at certain critical instants in time, topological events occur that cause a change in the Delaunay diagram.

The Dynamic State of a Moving Plane

Journal of Engineering for Industry, 1973
Salient loci existing for special properties of the nth-order motion state are investigated. Generalized analytical expressions are given for the loci as functions of the motion parameters in a rectangular coordinate system. Metric geometry is used to show that the well known Bresse circles are the proper circles to a pencil of circles. Circles similar

Stresses Produced in a Half Plane by Moving Loads

Journal of Applied Mechanics, 1958
Abstract A study is made of stresses and displacements induced in an elastic half plane (plane strain) by a concentrated line load moving at a constant speed along its surface. The stress field for an arbitrary load distribution can be built up by superposition of these concentrated-load solutions.
