    Computing systems capable of simultaneously executing a number of tasks may become more important in the future.1 This paper considers an implication of this trend in the field of numerical analysis. We aim to give an informal description of one means whereby parallelism can be produced and exploited. A particular technique for the development of additional parallelism in conventional s...

    Three generations of programming systems have provided realtime ground support for manned spaceflight programs. The first of these was the Mercury system, which became operational in 1960.1 The third and current system supports the Apollo program. The subject of this paper is the second in the series, the Gemini system, developed for NASA at the Manned Spaceflight Center in Houston, Tex... View full abstract»

    During an investigation of several project network techniques for their applicability to the effective description of business problems, it became evident that more efficient computer programs than those currently available could be written for large networks. Heretofore, critical-path computations have been divided into several phases. The experimental program described here employs a one-phase c... View full abstract»

    As part of a broader study dealing with the conversion of documents into machine-readable form, a procedure for machine-assisted proofreading was developed and investigated. The proofreading function was assumed to include correction of spelling errors and standardization of spelling variants. The purpose here is to describe the general procedure, which was based on an experimental dictionary and ... View full abstract»
