Application of a Multi - Purpose Computer System with Interactive Graphics
چکیده
197 A versatile computer system with interactive graphics is being used for the numerical modelling of antennas on aircraft. The POP-I I based system has been interfaced into an extensive computer network and to laboratory experiments, providing several stand-alone and terminal modes of operation supported by corresponding software. The special man-computer relationship made possible, overcomes the limitations frequently present in simulation stud ies of real world phenomena that require large-scale computation and which are usually carried out in the "stand-off" mode of batch computation. The dynamics of the usage of the system is illustrated by an a nimated slide sequence. The manipulation and display of input files, interaction with host machines, display and comparison of experimental and simulation results in an integrated fashion demonstrate the means by which a special awareness is brought about to assist the creativity and productivity of the researcher. Resume Un systeme versatile d'informatique complete d 'un traceur de courbe interactif est employe pour I 'analyse numerique de modeles d 'antennes aeronautiques. Ce systeme a base de POP-I I a ete mis en interface avec un rcseau etendu d 'ordinateurs ainsi qu 'avec des experiences en laboratoire, fournissant surtout plusieurs modes d 'operations de tele-commande (par terminal) et d 'autocommande, soutenue par leur logiciel respectif. eette relation unique entre I 'homme et I 'ordinateur surmonte, une fois reussie, les limita tions souvent presentes dans les etudes en sim ulation digitales de phenomenes reels, qui requierent la programmation de grande envergure, lesquelles etudes sont habituellement complctees dans le mode ' stand-off' du ca\Cul en fournee. La dynamique d 'usage du systeme est illustrce par une sequence de diapositives de caractcre animc. La manipulation et I'c talage des tableaux d'entn!e, I'interaction avec les ordinatellrs-h6tes. I'ctalage et la comparaison des rcsultats experimentaux et des calculs de simulation digitales demontrent d 'une fa~on integree les moyens par lesquels line conscience spcciale emerge pour assistcr le chcrcheur dans sa creativite et sa prod uctivitc.
