An automated, computerized color-vision test was designed to diagnose congenital red-green color-vision defects. The observer viewed a yellow appearing CRT screen. The principle was to measure increment thresholds for three different chromaticities, the background yellow, a red, and a green chromaticity. Spatial and temporal parameters were chosen to favor parvocellular pathway mediation of thr...

A (d, )-list disjunct matrix is a non-adaptive group testing primitive which, given a set of items with at most d “defectives,” outputs a superset of the defectives containing less than non-defective items. The primitive has found many applications as stand alone objects and as building blocks in the construction of other combinatorial objects. This paper studies error-tolerant list disjunct ma...

In a previous communication (Smith and Record, 1955) it was observed that there appeared to be an association between mongolism and primogeniture which invites investigation of the fertility of mothers of mongols. Such a study is by no means new. It has been attempted by many previous workers, prompted perhaps by the observations that the risk of producing a mongol increases sharply with advanc...

A true man wants to move the world if he can; he is not satisfied with taking a stone out of the way if he can lift the earth itself to a loftier level." ^ ^ pierson Thinking for a moment of education as a whole, I consider we teachers of these little ones hold an exceedingly responsible and important position therein. We are, as it were, dealing with the foundation of the building, the source ...

The seminary was concerned with questions arising in computing when the inputs to the computation can be corrupted. Such studies have implications for the manipulation, retrieval and transmission in the presence of errors and noise and they are related to many fields in Computer Science, Mathematics and Information Theory. Important technical tools come, e. g., from combinatorial search theory ...
