[en] More and more, computers have been incorporated into the day-to-day work environment of the radiologist. This text endeavors to give the radiologist a reasonable understanding of the computer operation, including the basic principles techniques applications and impact on the field of radiology

[en] This standard presents guidelines for the documentation of engineering and scientific computer programs. Good documentation promotes understanding, reduces duplication of effort, eases conversion to different computer environments and aids modification for extended applications. Good documentation is essential for implementation and effective use of programs obtained from other installations. Since the intention of this standard is to encourage better communication between the developer and user, it should be regarded as a guide rather than a set of rigid specifications. As a guide, it is sufficiently comprehensive to apply to large-scale programs intended for extensive external use. Not all features of this document are appropriate in all circumstances. In general, as the project complexity increases so does the need for more complete documentation. An organization may have special documentation requirements which supersede or extend these guidelines. This standard is a revision of ANS-STD.2-1967 and supersedes it

[en] A library for graphic representation, named Elbereth, has been built, all the subroutines have been written in Fortran-V for the Univac-1100/80 computer from J.E.N. and are able to produce drawing on the Calcomp-936 plotter, as well as with the printers and on the UTS-400 terminal screen. The library can yield two or three-dimensional plots as well as level lines, all of them under free format or in several standard ones either. It allows to be used on a simplified way by direct reading from a file. It has been constructed too with a flexible structure to allow forthcoming extensions. (author)

[en] The CYBERPLUS parallel processing system is the first in a series of parallel processors available from Control Data Corporation. The near-supercomputer performance of even a single CYBERPLUS processor can provide high-speed scalar capability for scientific and business applications. The author presents the basic concepts of the CYBERPLUS processor and the capabilities inherent in the features of the parallel processing system. (Auth.)

[en] A supercomputer is - in a nutshell - an enormously powerful computer. The APE (Array Processor Experiment) 100 supercomputer developed by Italy's National Institute for Nuclear Physics (INFN) performs one hundred billion arithmetic operations per second - around one hundred thousand times the speed of a personal computer, or ten thousand times the speed of the kind of workstation used by design engineers or many research labs. This huge increase in performance opens the way to many applications inconceivable with a normal computer, such as simulating the behaviour of the earth's atmosphere to study climate change, or simulating the combustion process in a large power plant and observing in detail the development of each chemical reaction to obtain accurate estimates of pollutants
