Provides an algorithm for determining the median and quartiles of discrete data sets. Describes the graphical equivalent of the numerical method. (JM)

Studies of stereo vision guide research on how animals see and how computers might accomplish this human activity. Discusses a sequence of algorithms to first extract information from visual images and then to calculate the depths of objects in the three-dimensional world, concentrating on stereopsis (stereo vision). (JN)

Views information as residual or catalytic form of energy which regulates other forms of energy in natural and artificial systems. Parallel human information processing (production systems, algorithms, heuristics) and information measurement are discussed. Suggestions for future research in area of parallel information processing include a matrix…

Considers three powerful techniques--heuristics, context trees, and search via backward chaining--that a knowledge engineer might employ to develop an expert system to automate performance engineering, i.e., the branch of instructional technology that focuses on the problems of business and industry. (MBR)

Discusses the functions of using visuals in communicating and comprehending information. (AEA)

An algorithm for the assembly of multiple test forms is proposed in which the multiple-form problem is reduced to a series of computationally less intensive two-form problems. At each step one form is assembled to its true specifications; the other form is a dummy assembled only to maintain a balance between the quality of the current form and the…

The brief therapy approach to counseling was born in the post-World War II cybernetics movement. The shift from a problem focus to a solution focus altered the way in which counselors approached helping clients out of their inflexible cognitive representations. Alongside this evolution in psychotherapy were the growth of research in artificial…

This article explains the generation of Kaprekar's constant in terms that upper elementary pupils can understand. The procedure is explained and the result proven. This is an example of a new, interesting problem for students that gives them drill in subtraction at the same time. (LS)

A model for the analysis of paired comparison data is presented which is metric, mathematically tractable, and has an exact algebraic solution. (Authors/MB)

The problem of rounded numbers used in computations on digital computers is discussed and examples showing the effect of round-off errors are given. (DT)
