title	Design of Control Systems for Performance : A Constraint Mapping Approach
source	17 p. : ill Engineering Design Research Center, CMU, October, 1989. EDRC 24-10-89. includes bibliography.
summary	Simple s-plane maps are used to graphically reveal interactions of performance requirements and constraints thus providing a control system designer insight into performance trade-offs. Two well-known but powerful ideas underlie this approach: (a) the characteristic equation of an nth-order system can be fully described by the specification of n variables and (b) any dynamic performance requirement or constraint can be expressed in terms of 2n variables of which n describe the open-loop and n describe the closed-loop characteristic equations. An example illustrates the application of the approach to controller design

title	Computing and Design in the Canadian Schools of Architecture and Landscape Architecture: A Proposed Research Agenda for Integrated CAD & GIS in the 1990's

summary	Conventional computer systems currently used by architecture and landscape architecture are not addressing complex decision making, system interface, dynamic manipulation and real time visualization of data. This paper identifies a strategy by which Canadian Schools could form a supportive network, incorporate and expand their research development. Within this larger framework schools would have better tools, a larger research base and access to funding as a group. The following discussion is an idea of what we at the Canadian Schools need to do differently over the next five years in our research and teaching in order to make a unique contribution to our fields.

title	Computer Modeling: A First Course in Design Computing

summary	Computation in design has long been a focus in our department. In recent years our faculty has paid particular attention to the use of computation in professional architectural education. The result is a shared vision of computers in the curriculum [Woodbury 1985] and a set of courses, some with considerable historyland others just now being initiated. We (Dave and Woodbury) have jointly developed and at various times over the last seven years have taught Computer Modeling, the most introductory of these courses. This is a required course for all the incoming freshmen students in the department. In this paper we describe Computer Modeling: its context, the issues and topics it addresses, the tasks it requires of students, and the questions and opportunities that it raises. Computer Modeling is a course about concepts, about ways of explicitly understanding design and its relation to computation. Procedural skills and algorithmic problem solving techniques are given only secondary emphasis. In essential terms, the course is about models, of design processes, of designed objects, of computation and of computational design. Its lessons are intended to communicate a structure of such models to students and through this structure to demonstrate a relationship between computation and design. It is hoped that this structure can be used as a framework, around which students can continue to develop an understanding of computers in design.

title	CAD Tools for Systems Theory and Bottom Up Design
doi	https://doi.org/10.52842/conf.acadia.1989.209
source	New Ideas and Directions for the 1990’s [ACADIA Conference Proceedings] Gainsville (Florida - USA) 27-29 October 1989, pp. 209-226
summary	The use of CAD is investigated in the teaching of systems theory to a fourth year group of design students. A comparison is made between the CAD group using MacArchitrion and a non-CAD group using traditional design methods. The paper includes a discussion of the meaning of systems design theories, relates the CAD and non-CAD student design methods and illustrates the results. It also includes recommendations for improvements so the computer can become more effective in this type of design teaching. Finally, it concludes with recommendations from the students at the end of the semester project. The basic premise for the CAD design group is that computers should encourage students to understand and use systems design theory.

title	Ground Sculpture on CADD: Forming and Coloring the Landform in a Graphic Data Base
doi	https://doi.org/10.52842/conf.acadia.1989.049
source	New Ideas and Directions for the 1990’s [ACADIA Conference Proceedings] Gainsville (Florida - USA) 27-29 October 1989, pp. 49-59
summary	A graphic data base of our campus is being developed to record physical inventory and to provide a three- dimensional development tool for the University. The campus has many changes in elevation. Computer terrain modeling is planned to provide traditional contour information as well as to furnish a base for perspective views of the campus. Selecting an appropriate geometry to record the landform, and determining criteria for coloration of the ground surface is critical to the success of the project. Methods of modeling a three-dimensional surface are discussed; color principles which articulate landform are explored. A methodology is illustrated which achieves a flexible model of the campus landform.

title	The Computability of Architectural Knowledge

summary	In an important contribution to the theoretical foundation of design computing, Mitchell noted "an increasingly urgent need to establish a demonstrably sound, comprehensive, rigorously formalized theoretical foundation upon which to base practical software development efforts" (Mitchell, 1986). In this paper we propose such a theoretical framework. A basic assumption of this work is that the advancement of design computing is dependent upon the emergence of a rigorous formulation of knowledge in design. We present a model of knowledge in architectural design which suggests a promising conceptual basis for dealing with knowledge in computer-aided design systems. We require models which can represent the formal knowledge and manipulative operations of the designer in all of their complexity-that is formal models rather than just geometric models. Shape Grammars (Stiny,1980) represent an example of such models, and constitute a relatively high level of design knowledge as compared to, for example, use of symmetry operations to generate simple formal configurations. Building upon an understanding of the classes of design knowledge as the conceptual basis for formal modeling systems may contribute a new realization of the potential of the medium for design. This will require a comprehensive approach to the definition of architectural and design knowledge. We consider here the implications of a well-defined body of architectural and design knowledge for design education and the potential mutual interaction-in a knowledge-rich environment-of design learning and CAAD learning. The computational factors connected with the representation of design knowledge and its integration in design systems are among the key problems of CAAD. Mitchell's model of knowledge in design incorporates formal knowledge in a comprehensive, multi-level, hierarchical structure in which types of knowledge are correlated with computational concepts. In the main focus of this paper we present a structured, multi-level model of design knowledge which we discuss with respect to current architectural theoretical considerations. Finally, we analyze the computational and educational relevance of such models.

summary	The article describes an approach to teaching syntactical aspects of design and architectural composition by means of exercises utilizing various computer graphics programs. The theoretical assumptions and the background of formal studies are reviewed as sources of this approach. A working definition of Architectural Knowledge and Design Knowledge is postulated as the theoretical foundation of Computer- Aided Learning. The term, Architectural Syntax, is proposed as the formalization of this knowledge. The pedagogical significance of computers as a medium of design education is analyzed, and the particular role of syntactical knowledge in design, the computation of design and in C A.L. in design is identified. An outline of the course, The Joy of Syntax, is described and future research and development in these fields discussed.

title	Interactive Animation on the Macintosh II
doi	https://doi.org/10.52842/conf.ecaade.1989.x.a0t
source	CAAD: Education - Research and Practice [eCAADe Conference Proceedings / ISBN 87-982875-2-4] Aarhus (Denmark) 21-23 September 1989, pp. 9.5.1-9.5.6
summary	The efficiency of images in communication between humans has so far been used almost exclusively by TV and other mass medias. The costs have been too great to encourage the use of images in the financially restricted everyday practice of architecture. With a range of application programs for the Apple Macintosh II the vision has come close to reality. It is now possible to create guided walks with the chance to choose different routes and views in a model of buildings and surroundings in 256 colour graphics. The makers of these programs may not have foreseen this use for their products and that is why it takes quite a lot of effort to make all the necessary images. With some supplementary routines however, this will be made much easier. Animation can also be used to visualize different processes inside a building. We have been studying the working environment in mechanical industry. The goal of this project is to make communication possible between the workers at all levels of an organization in planning changes and has so far been very successful. The use of this technique is only limited by our imagination and funding. Some examples to be tested in the near future are "Escape at a fire", "Animation of a Dairy", "Traffic situations in a parking lot-, "CAD-working place" and others. One of the difficulties in interactive planning with users has been to come close enough to their reality. With animated images it is possible to visualize what is going to happen and what it is going to look like in a more understandable way. In education this must be a challenging possibility. Changes and processes are some of the most difficult subjects to describe and explain! The software used is a handful of individual programs which, thanks to the graphics standards of the Macintosh, can exchange data with each other.

summary	In the announcement of the sixth eCAADe Conference we stated that It is held at a time where CAAD is moving into practice very fast, with heavy influence on research and education. We stated that research is directed towards the early design phases, and that education is facing the problem of mass education. In that situation much benefit can be obtained from collaboration with practice. We decided to give the conference the title “CAAD: Education - Research and Practice” to state the importance of practice as a test bench. The conference papers cover education and research in depth in many important areas and give a good overview, whereas the practical theme is more or less missing, indicating, that experience here is still modest. At the lecture material market and the exhibition the situation is opposite and shows state of art in practical use.

title	Computational Design Instruction: Toward a Pedagogy

summary	The computer offers enormous potential both in and out of the classroom that is realized only in limited ways through the applications available to us today. In the early days of the computer it was generally argued that it would replace the architect. When this idea became obsolete, the prevailing opinion of proponents and opponents alike shifted to the notion of the computer as merely adding to present design capabilities. This idea is so ingrained in our thinking that we still speak of "aiding" design with computers. It is clear to those who grasp the real potential of this still new technology - as in the case of many other major technological innovations - that it continues to change the way we design, rather than to merely augment or replace human designers. In the classroom the computer has the potential to radically change three fundamental ingredients: student, instruction, and instructor. It is obvious that changes of this kind spell out a commensurate change in design pedagogy. If the computer is going to be more than a passive instrument in the design studio, then design pedagogy will have to be changed, fundamentally. While the practice of computing in the studio continues to be a significant I aspect of architectural education, articulation of viable pedagogy for use in the design studio is truly rare. In this paper the question of pedagogy in the CAD studio will be considered first. Then one particular design studio taught during Fall 1988 at Carnegie Mellon University will be presented. Finally, we shall return to issues of change in the student, instruction, and instructor, as highlighted by this particular experience.

summary	Should we teach CAAD? - yes, but why? Answer to this question is clear too. Question three - "when?" - on the 5, 6 and 7 term. Why so rate? - it is a compromise because "Architecture is an art" and students of architecture should know how to make a project without computers. How to teach CAAD? - we should teach haw to use professional computer programs and not programming. We must work out a new manual for architects. It should be constructed in such a way as to correspond to consecutive steps of the architectural design process.

summary	In this paper the author will consider four key concepts: design, evaluation, models, and representation. In combination, definitions of these concepts impinge on each other and they are further conditioned by the author intention to represent design knowledge within computers. The issue of human-computer interaction then becomes critical to the usefulness of knowledge representations for designers

summary	Knowledge-based systems are becoming pervasive in the computer-aided design area. For these systems to achieve satisfactory levels of performance large amounts of knowledge are necessary. However, the acquisition of knowledge is a difficult and tedious task. Automated knowledge-acquisition tools (AKAT) provide capabilities for quickly building and maintaining knowledge-bases. This paper describes the CGEN AKAT, which allows hardware designers, unfamiliar with artificial intelligence programming techniques, to deposit their expertise into a synthesis tool's knowledge-base. A set of experiments which tested CGEN's capabilities are presented. The experiments show that with CGEN hardware designers can produce high quality knowledge-bases
