A dispersion pass algorithm for the polyphase merge

This paper presents a new manner of dispersing strings for a Polyphase merge. If the number of strings dispersed is between two levels acceptable by Polyphase merge, a more economical technique of reaching the next level for  …

Syntactic analysis by digital computer

This paper provides an account of the Shadow language that is used to describe syntax and of a corresponding subroutine that enables a computer to perform syntactic analysis. The input to this subroutine consists of a string  …

Computer pattern recognition techniques: electrocardiographic diagnosis

The use of programmed digital computers as general pattern classification and recognition devices is one phase of the current lively interest in artificial intelligence. It is important to choose a class of signals which is,  …
