Early Computing at the University of Alberta and the Introduction of the LGP-30
To re-create the University of Alberta's computing milieu of some 40 years ago, this article surveys the university's computational procedures before the arrival of the first computer and discusses the university's acquisition and use of the LGP-30
A SECOND SURVEY OF DOMESTIC ELECTRONIC DIGITAL COMPUTING SYSTEMS..
Abstract : Based on the results of a third survey, the engineering and programming characteristics of 222 different electronic digital computing systems are given. The data are presented from the point of view of application, numerical and arithmetic characteristics, input, output and storage systems, construction and checking features, power, space, weight, and site preparation and personnel requirements, production records, cost and rental rates, sale and lease policy, reliability, operating experience, and time availability, engineering modifications and improvements and other related topics. An analysis of the survey data, fifteen comparative tables, a discussion of trends, a revised bibliography, and a complete glossary of computer engineering and programming terminology are included.
Table of the reciprocal of the gamma function for complex argument
Noordhoff's Wiskundige Tafels in 5 Decimalen. 5de druk van Tafel H. By P. WIJDENES. Pp. viii, 269. 8.75 Dutch florins. 1953. (P. Noordhoff, Groningen) This is one of several tables published by Noordhoff and edited, alone or jointly, by MTijdenes. The small passages of text are mostly in six languages ; the English title is Mathematical Tables to 5 Decimal Places. Most of the volume is occupied by logarithmic and trigonometrical tables, the ordinary sexagesimal units of angle being used. The angular interval is normally l', but is reduced to 10" or 1" in the case of some functions of small arguments. There are other elementary tables, and the volume concludes with several brief tables of higher functions (factorial function, exponential integral, sine and cosine integrals, error integral, Bessel functions). There appears to be no information which cannot fairly easily be found elsewhere, but the collection as a whole may suit some of those for whom it is intended, namely " students and laboratory workers in universities and technical or service colleges ". The book is excellently printed and bound ; users will find it convenient that Tables 11-111 and V are distinguished by being printed on shell pink and pale green paper respectively. A. F.
