The implementation of an unstable system with a realizable stable system

Unstable systems are normally confronted in control, signal processing and communication systems when one tries to model the inverse of a plant for output control and the inverse of a filter or transmission channel characteristics in the frequency domain for the equalization of the distortion. Various methods are shown and proved in this tutorial paper to approximate an unstable system by stable ones. The idea is to model an unstable system with a noncausal one and then implement it with an appropriate delay. The methods are applicable for both analog and digital systems.

The Ada task system and real-time applications: an implementation schema

The Ada task system is critically evaluated from the point of view of real-time applications. Based on such an evaluation an abstract machine, supplying both an operational semantics and an implementation schema for it, is derived. Such a schema, depending on parameters, may supply a standard implementation following the Ada Reference Manual specifications, or may allow the user to implement ad hoc policies required by the time constraints of the specific application.

OMAX+ an advanced quality improvement measurement system

This paper describes OMAX+, a microcomputer based quality improvement measurement system developed by the Oregon Productivity and Technology Center at Oregon State University.

OMAX+ is a modified and enhanced version of the Objectives Matrix approach for productivity and quality measurement developed by the late James L. Riggs, Head of the Department of Industrial Engineering. OMAX+ is specifically designed for use by organizations engaged in Total Quality Control (TQC) efforts. Use of OMAX+ presents the industrial engineer engaged in TQC with a useful measurement tool to quantify and track quality improvements. The paper discusses the approaches that will enable the OMAX+ measurement system to be integrated into new or on-going quality improvement programs. OMAX+ is a self-contained program for IBM personal computers and true compatibles. A version with additional graphics capabilities is being developed by the Oregon Productivity and Technology Center for use on Macintosh Computers.

OMAX+ has been successfully used by several industries and service organizations in the Northwestern United States.

Object-oriented implementation issues in an experimental CAD system

This case study of object-oriented program design illustrates two limitations of object-oriented programming languages. Existing object-oriented languages do not have good facilities to support two key program design problems: the definition of composite objects, or data structures that include sets of related subobjects; and the specification and run-time management of temporary data structures required to implement efficient algorithms. Both composite objects and temporary data structures are important to the construction of a wide variety of programs. We use the design and implementation of an interactive computer-aided design system to describe how the limitations of present object-oriented languages complicate the design of composite objects and temporary data structures.     

The work compatibility improvement framework: an integrated perspective of the human-at-work system

Lapos;appareil a été concu de façon à reproduire les caractéristiques principalos do la machine à trier les lottres en usage à la Poste beige, ot à permettre en plus la détection automatique des erreurs et Le fonctionnement soit à vitesse imposée (VL) soifc à vitesse libre (VL). Dix-huit opératcurs entrainés ont aervi de sujets. lis ont d'abord trié 500 destinations à chacune des 4 vitessos imposées (40, 50, 60 et 70/minnte) en memo temps qu'unmemo nombre de destinations a VL. L'augmen. tation do la cadence à VI a'accompagne d'une augmentation importante de proportions d'errours, do reponses tardives et d'omissions. II y a de fortes differences individuelles maia pour 1'enaomble du groupo on pout estimcr que lo fait d'imposer une cadence egalo a la vitesse moyenne adoptee a VL ferait que 80 pourcent seule-mont des destinations recovraient une reponse en temps utile, dont environ 10 pourcent d'errours (contro moins de 2 pourcent a VL). Quand la cadonco imposed est suporieuro a la vitosso realiseo par un sujet a VL, il y a presque toujours plus d'erreurs a VI. Au cours d'une seance, chaquo sujet a travaille a VI a une cadence ogale a la vitesse qu'il venait do realiser a VL. On a de nouveau observe une proportion d'erreurs plus importanto a VI (9 pourcent au lieu de 3 pourcent) bien que la vitesse effective (en termes de reponses donnees en temps utile) fut inferieure. L'analyse detaillee d'un echantillon de cycles à VI a montré quo la prossion de vitesse présente un caraétoro cumulatif. Les erreurs et les éeponses tardives so produisent principalemont apres vino reponse doruiSe dans lo voisinage ou après la fin do la periode d'acceptation. D'autre part, uno tendance a n'omettre de ropondro quo dans Los cas de pression de vitesso extreme a 6te miso en evidence. Tous cos resultats ont été obtenus avec presentation anticip6o do la destination suivanto a chaque cycle. Uno comparaison avec lo travail a VL sans presentation anticipee montre que dans la condition precécédente los sujets lisent generalement la destination suivanto avant de répondre.
