Digital optical iterative pattern recognizer
An optical pattern recognizer which classifies an input sequence into one of two classes is described. The language of regular expressions is used to identify a set of input sequences to be recognized. The system is realized ...
Generation of moire contours with acousto-optic cells
Moire contours are seen on a curved surface viewed through a grating when the surface is illuminated with a matched grating. We have been able to replace both the projection and viewing physical gratings with gratings of ...
On a duality principle in processes of servicing machines with double control
This paper examines a doubly controlled process of servicing machines. The classical system treated by Takács is equipped with m+1 unreliable machines served by one repairman. In the present modification of this model, the ...
