    Problems in modeling the software development process as an adventure game
    (1993) Ludewig, Jochen
    SESAM (Software Engineering Simulation by Animated Models) is a simulator for practicing the role of a software project manager. Its long term goal is to provide a tool for training CS students. As a research project, SESAM calls for an integrated model of the software development process, reflecting and quantifying many phenomena observed in real software projects. We are currently using the second prototype, which can already demonstrate some rational behaviour. More important, however, were our observations in the process of constructing SESAM. They shed light on the current state of software engineering, and on the applicability of metrics. SESAM is being developed in an evolutionary style by the Software Engineering Department (Lehrstuhl) at Stuttgart University; it is implemented in Smalltalk-80 on Unix-Workstations. This paper concentrates on the fundamental questions raised by the work on SESAM. A more complete description of our work has been published before.

    Trends in picture communication
    (1993) Speidel, Joachim
    In the past years significant progress was made with digital transmission of audiovisual services and most interesting trends are visible for the future. Such applications encompass interactive services, like videoconferencing, ISDN-videophone, storage of moving video and audio in computers or on CD, e.g. for multimedia applications. For distribution services, there is an unbroken trend from TV to HDTV. Strong emphasis is on compressed digital video even for transmission to the home.

    Wiederverwendung als Wunderwaffe?
    (1993) Plödereder, Erhard
    Die Wiederverwendung von Software wird derzeit als geeignete Methode angesehen, dem Anstieg der Komplexität und der Entwicklungskosten entgegenzuwirken. Eine erfolgreiche Wiederverwendung verspricht klare Vorteile. Wiederverwendung ist keine Wunderwaffe. Sie ist aber Bestandteil einer umfassenden Strategie für das Software-Engineering, mit der Qualität und Produktivität schrittweise verbessert werden können.

    Sprachen für das Software-Engineering
    (1993) Ludewig, Jochen
    Dieser Beitrag diskutiert Sprachen und Notationen aus der Sicht des Software Engineerings, also nicht wie sonst üblich aus der Perspektive der Codierer oder der Sprachschöpfer und Übersetzerbauer. Natürlich ist Vollständigkeit auf diesem weiten Feld weder erreichbar noch angestrebt. Nach der Klärung einiger Grundbegriffe wird die Situation vor 25 Jahren der heutigen gegenübergestellt; einzelne Aspekte der modernen Sprachen werden näher betrachtet. Schließlich wird der Zusammenhang der Sprachen mit Werkzeugen und Methoden angesprochen. Thesen am Schluß des Artikels fassen die wichtigsten Aussagen und Folgerungen pointiert zusammen.

    Software-Wiederverwendung
    (1993) Ludewig, Jochen
    Wiederverwendete Software ist billiger als eine Neuentwicklung und hat in der Regel weniger Fehler. Zudem trägt sie zur Standardisierung bei. Diese und andere Vorteile sprechen für die Wiederverwendung von Software. Ihrer Förderung stehen aber auch Hindernisse im Weg.

    Representing time in multimedia systems
    (1993) Wahl, Thomas; Rothermel, Kurt
    As multimedia systems deal with a variety of temporally interrelated media items, synchronization is an important issue in those systems. One part of synchronization is the representation of temporal information. In contrast to traditional computing tasks, multimedia imposes new requirements on the representation of time. Specifically, a fine-grained and a flexible temporal model is required. Therefore, a number of temporal models have been suggested by various authors. This paper evaluates and classifies a selection of the most common existing models applying fundamental statements of the time theory and temporal logic. Learning from the deficits of the existing models, a new temporal model based on interval operators is proposed for multimedia systems.

    ArabTeX : a system for typesetting Arabic; user manual version 3.00
    (1993) Lagally, Klaus
    ArabTeX is a package extending the capabilities of TeX/LaTeX to generate the Arabic writing from an ASCII transliteration for texts in several languages using the Arabic script. It consists of a TeX macro package and an Arabic font in several sizes, presently only available in the Naskhi style. ArabTeX will run with Plain TeX and also with LaTeX. It is compatible with NFSS, NFSS2 and the EDMAC package; other additions to TeX have not been tried. ArabTeX is primarily intended for generating the Arabic writing, but the standard scientific transliteration can also be easily produced. For languages other than Arabic that are customarily written in the Arabic script some limited support is available. ArabTeX defines its own input notation which is both machine, and human, readable, and suited for electronic transmission and Email communication. However, texts in some of the Arabic standard encodings can also be processed. ArabTeX is copyrighted, but free use for scientific, experimental and other strictly private, noncommercial purposes is granted. Offprints of publications using ArabTeX are welcome. Using ArabTeX otherwise requires a license agreement. There is no warranty of any kind, either expressed or implied. The entire risk as to the quality and performance rests with the user.
