title	Comprendre KEOPS: Logiciel de conception assistee par ordinateur en architecture
doi	https://doi.org/10.52842/conf.ecaade.1983.x.s9f

summary	En informatique graphique, la méthode la plus courante pour saisir un bâtiment consiste à dêcrire et à stocker en base de données les "pleins": les murs, planchers, composants. Cette procédure est vite fastidieuse, et ne permet pas réellement une véritable conception assistée par ordinateur. KEOPS expérimente une autre méthode qui consiste à décrire l'esquisse par ses "vides", c'est-à-dire les volumes des locaux en trois dimensions. Le logiciel opère automatiquement la transformation "filaire" en composants et ouvrages du bâtiment en exploitant un savoir technologique. Le benéfice? La réduction spectaculaire du temps de saisie et un logiciel de C.A.O. enfin opérationnel en bâtiment.

title	Towards a Comprehensive User Interface Management System
source	computer Graphics. July, 1983. vol. 17: pp. 35-42 : ill. includes bibliography
summary	A UIMS developed at the University of Toronto is presented. The system has two main components. The first is a set of tools to support the design and implementation of interactive graphics programs. The second is a run-time support package which handles interactions between the system and the user (things such as hit detection, event detection, screen updates, and procedure invocation), and provides facilities for logging user interactions for later protocol analysis. The design / implementation tool is a preprocessor, called MENULAY, which permits the applications programmer to use interactive graphics techniques to design graphics menus and their functionality. The output of this preprocessor is high- level code which can be compiled with application-specific routines. User interactions with the resulting executable module are then handled by the run-time support package. The presentation works through an example from design to execution in a step-by-step manner

title	Logic Programming as a Representation of Knowledge
source	IEEE Computer. IEEE Computer Society, October, 1983. vol. 16: pp. 106-110 : ill. includes bibliography
summary	Logic has traditionally provided a firm conceptual framework for representing knowledge. As it can formally deal with the notion of logical consequence, the introduction of Prolog has made it possible to represent knowledge in terms of logic and also to expect appropriate inferences to be drawn from it automatically. This article illustrates and explores these ideas with respect to two central representational issues: problem solving knowledge and database knowledge. The technical aspects of both subjects have been covered elsewhere (Kowalski, R. Logic for problem solving, North- Holland pub. 1979 ; Dahl, V. on database system development through logic ACM Trans.vol.7/no.3/Mar.1982 pp.102). This explanation uses simple, nontechnical terms

title	Before Programming : On Teaching Introductory Computing
source	1983? 10 p. includes bibliography
summary	In comparison with most other human intellectual activities, computing is in its infancy despite the progress we seem to have made in such a short time. Consequently, there has been insufficient time for the evolution of 'best ways' to transmit computing concepts and skills. It is therefore prudent to look to more mature disciplines for some guidelines on effective ways to introduce computing to beginners. In this respect the discipline of teaching people to read and write in a natural language is highly relevant. A fundamental characteristic of this latter discipline is that a substantial amount of time is devoted to teaching people to read long before they are asked to write stories, essays, etc. In teaching computing people seem to have overlooked or neglected what corresponds to the reading stage in the process of learning to read and write. In the discussion which follows the author looks at ways of economically giving students the 'computer-reading experience' and preparing them for the more difficult tasks of algorithm design and computer problem-solving

source	Proceedings of the International Conference eCAADe [European Computer Aided Architectural Design Education] Brussels (Belgium) 1983, pp. II.1-II.9
summary	A 6 weeks (2 days a week) design exercise, making use of the above programs, was held the last bimester in the Faculty of Architecture in TH Delft. This exercise was an experimental one for the students, as well as for the teachers. As the exercise had an experimental character, it is clear that a lot should be learned from that experience, both from its positive and negative outcomes. The paper will try to evaluate on this point for the benefit of those intending to set up similar projects.

summary	The educative proposal was based on the summary attained through experiences piled up during the 2 last semester courses, 2/2006-1/2007. This proposal corresponds to a mix of methodology (by personal attendance / by internet). Founding on the Theory of the Game (Eric Berne 1960) and on different theories such as: Multiple intelligences (Haward Gardner 1983), Emotional Intelligence (Peter Salowey and John Mayer 1990, Goleman 1998), Social Intelligence (Goleman 2006), the Triarchy of Intelligence (Stemberg, R.J. 1985, 1997), “the hand of the human power”, it´s established that the power of the voice, that of the imagination, the reward, the commitment and association produce a significant increase of the productivity (Rosabeth Moss Kanter 2000), aside from the constructive processes of the knowledge (new pedagogical concepts constructivista of Ormrod J.E. 2003 and Tim O´Reilly 2004).

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title	The Use of Gable OMS (Object Modelling System) in the Building Design ProcessThe Use of Gable OMS (Object Modelling System) in the Building Design Process

summary	GABLE CAD SYSTEMS comprise a suite of integrated sub-systems, one of which is OMS. The use of OMS in the development of a building design enables three dimensional graphical modelling of objects associated with buildings. Thus furniture, fittings and fixtures may be located within any room in a building or outside a building or in relation to other groups of objects unrelated to a building. Once located, objects and building may be seen in 2D plan and elevation/section projection or 3D projection (perspectives, axonometrics, isometrics, etc.). In this way furniture, people, cars, trees,landscape objects may all be modelled and graphically represented in addition to the modelling capabilities enabled using GABLE BMS (Building Modelling System). These graphically represented 2D and 3D views of objects can then be passed into GABLE IDS for further embellishment, annotation or dimensioning to produce detailed working drawings.

title	CAD Technology Transfer: A Case Study
doi	https://doi.org/10.52842/conf.acadia.1990.133

summary	Transferring innovative university-based research results to the industry or practice that will ultimately use them is an arduous, time-consuming effort. One way to effect this technology transfer is to develop a demonstrable prototype product and then find or form a corporation that can expand the prototype into a full product and market it to the profession. Another way, which can shorten the transfer process, is to "sell" the idea, rather than the product, to a corporation that has the vision, the resources and the technical competency to support its development, with the intent to eventually market it. In this paper, we describe a case study of this latter approach, based on our seven year experience of researching, developing and transferring innovative architectural CAD technology. We describe the birth, growth, and maturity of Worldview, a computer-aided design and modeling system for use by architects. The project was initiated in 1983, and went through five software versions, numerous grants and grant extensions, two granting corporations, and extensive field testing. The software has developed into a mature system, with sufficient functionality appropriate for commercial distribution. The paper describes not only the factual chronology of the project, but also highlights the advantages and drawbacks of market-oriented university research. We conclude with suggestions as to how the process may be improved, and how problems and obstacles can be minimized.

title	Supporting Reflection-in-Action in the Janus Design Environment
source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 247-259
summary	We have developed a computer-based design aid called Janus, which is based on a model of computer-supported design that we think has significance for the future of architectural education. Janus utilizes a knowledge-based approach to link a graphic construction system to hypertext. This allows the computer to make useful comments on the solutions that students construct in a CAD-like environment. These comments contain information intended to make students think more carefully about what they are doing while they are doing it. In other words, Janus promotes what Donald Schon has called "reflection-inaction" (Schon, 1983). The Janus design environment is named for the Roman god with a pair of faces looking in opposite directions. In our case the faces correspond to complementary design activities we call construction and argumentation. Construction is the activity of graphically creating the form of the solution e.g., a building. Traditionally this has been done with tracing paper, pencils, and pens. Argumentation is the activity of reasoning about the problem and its solution. This includes such things as considering what to do next, what alternative courses of action are available, and which course of action to choose. Argumentation is mostly verbal but partly graphical.

title	Case Study of Tacit Knowledge Sharing in a Distributed Design Studio
doi	https://doi.org/10.52842/conf.acadia.2003.107
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 107-116
summary	This paper demonstrates the effects of experts’ tacit knowledge on improving architectural students’ design artifacts in a distributed design studio. In geographically distributed design environments, the Internet is an important medium by which architects can share tacit knowledge in the form of dialogue via online communication technologies, such as online chat and Instant Messaging (IM). In spring 2003, the National Aeronautics and Space Administration (NASA) and 8 schools conducted a collaborative design studio to develop a crew restraint system for space flights. Online chat software was used as a primary communication channel. Throughout the entire design studio, NASA professionals served as knowledge holders while undergraduate students participated as knowledge seekers. An interpretive content analysis and case study methodology were used in this study. We qualitatively observed the interactions between NASA and the students based upon two aspects: knowledge reflection and design improvement. Data were collected using document analysis of all knowledge sources and students’ design artifacts. The findings of this study indicate that the online chat system is useful in sharing tacit knowledge for the early part of design processes in a distributed design environment. Experts’ tacit knowledge appears to not only influence how students understand problems, but how they initiate conceptual design. This study provides empirical evidence regarding tacit knowledge sharing, and strengthens Schon’s (1983) claim about knowledge reflection in design studio. Furthermore, this study introduces architectural practitioners to the practical necessity of tacit knowledge sharing. This study is significant because its findings indicate the appropriate knowledge management strategy for architectural practitioners.

title	APPLICATION OF SPATIAL DESIGN ABILITY IN A POSTGRADUATE COURSE
source	Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 75-82
summary	Spatial Design Ability (SDA) has been defined by the author (1983) as the capacity to anticipate the effects (psychological impressions) that architectural spaces or its components produce in observers or users. This concept, which requires the evaluation of spaces by the people that uses it, was proposed as a guideline to a Masters Degree Course in Architectural Design at the Universidad Autonoma de Aguascalientes in Mexico. The theory and the exercises required for the experience needed a model that could simulate spaces in terms of all the variables involved. Full-scale modeling as has been tested in previous research, offered the most effective mean to experiment with space. A simple, primitive model was designed and built: an articulated ceiling that allows variation in height and shape, and a series of wooden panels for the walls and structure. Several exercises were carried out, mainly to experience cause -effect relationships between space and the psychological impressions they produce. Students researched into spatial taxonomy, intentional sequences of space and spatial character. Results showed that students achieved the expected anticipation of space and that full-scale modeling, even with a simple model, proved to be an effective tool for this purpose. The low cost of the model and the short time it took to be built, opens an important possibility for Institutions involved in architectural studies, both as a research and as a learning tool.

summary	This paper reviews the state of the art in enumerative solution methods for the traveling salesman problem (TSP). The introduction (Section 1) discusses the main ingredients of branch and bound methods for the TSP. Sections 2,3 and 4 discuss classes of methods based on three different relaxation of the TSP: the assignment problem with the TSP cost function, the 1-tree problem with a Lagrangean objective function, and the assignment problem with a lagrangean objective function. Section 5 briefly reviews some other relaxations of the TSP, while section 6 discusses the performance of some state of the art computer codes. Besides material from the literature, the paper also includes the results and statistical analysis of some computational experiments designed for the purposes of this review

title	Disjunctive Programming and a Hierarchy of Relaxations for Discrete Optimization Problems
source	December, 1983. 38 p. : ill. includes bibliography
summary	The author discuss a new conceptual framework for the convexification of discrete optimization problems, and a general technique for obtaining approximations to the convex hull of the feasible set. The concepts come from disjunctive programming and the key tool is a description of the convex hull of a union of polyhedra in terms of a higher dimensional polyhedron. Although this description was known for several years, only recently was it shown by Jeroslow and Lowe to yield improved representations of discrete optimization problems. The author expresses the feasible set of a discrete optimization problem as the intersection (conjunction) of unions of polyhedra, and define an operation that takes one such expression into another, equivalent one, with fewer conjuncts. He then introduces a class of relaxations based on replacing each conjunct (union of polyhedra) by its convex hull. The strength of the relaxations increases as the number of conjuncts decreases, and the class of relaxations forms a hierarchy that spans the spectrum between the common linear programming relaxation, and the convex hull of the feasible set itself. Instances where this approach presents advantages include critical path problems in disjunctive graphs, network synthesis problems, certain fixed charge network flow problems, etc. The approach on the first of these problems is illustrated, which is a model for machine sequencing

summary	The approach of devising robust surface methods applicable to arbitrarily located data was taken by the CAGD Group at the University of Utah. Adopting two broad classes of methods suitable for solving the problems (i.e., problems for which simplifying geometric assumptions cannot be made): (1) surface interpolants defined over triangles or tetrahedra and (2) distance-weighted interpolants. Interactive computer graphics was used to display surfaces for adequate visualization. Although some figures were given, it must be kept in mind that some 3-D medium, or at least motion, is necessary to understand surfaces
