Fast Maze Router

Abstract: This paper describes a method of generating a path between two points of a cellular array, with some cells being specified as obstacles. The method combines two techniques: A line search is first directed toward the target. This is a fast and extremely effective method on boards with plenty of space. When the line search hits an obstacle, an expansion technique typical for the Lee-type algorithms is then used to “bubble” around the obstacle. The line search can then continue toward the target again.

The Scattering of Acoustic Waves by a Spherically Stratified Medium and an Obstacle

Abstract: The problem of the multiple scattering of a plane acoustic wave by a quasi-homogeneous spherically stratified medium of compact support and a bounded obstacle is considered. It is shown that this problem can be reformulated as a singular integral equation over the boundary of the scattering obstacle alone. The integral equation can be regularized and inverted in the space of continuous functions defined over the boundary of the scattering obstacle.

Are Middle Managers an Obstacle to Corporate Social Policy Implementation

The demand upon U. S. corporations to provide both money and manpower in the correction of social ills has gained considerable momentum in the last five years. While some corporations have been conspicuous leaders in devising corporate social responsibility programs, many more have experienced extreme difficulty not only in stating appropriate social responsibility policies, but more particularly in translating those policies into manageable programs. Even formulation of the statement of appropriate corporate social responsibility policies is not an easy task, given the conflicting standards under which corporate execu-
