title Computational intelligence: soft computing and fuzzy-neuro integration with applications
source Springer, Berlin
summary Soft computing is a consortium of computing methodologies that provide a foundation for the conception, design, and deployment of intelligent systems and aims to formalize the human ability to make rational decisions in an environment of uncertainty and imprecision. This book is based on a NATO Advanced Study Institute held in 1996 on soft computing and its applications. The distinguished contributors consider the principal constituents of soft computing, namely fuzzy logic, neurocomputing, genetic computing, and probabilistic reasoning, the relations between them, and their fusion in industrial applications. Two areas emphasized in the book are how to achieve a synergistic combination of the main constituents of soft computing and how the combination can be used to achieve a high Machine Intelligence Quotient.

title Freehand drawing system using a fuzzy logic concept
source Computer-Aided Design, Vol. 28 (2) (1996) pp. 77-89
summary A pen-based drawing system using a fuzzy logic concept has been developed. The Fuzzy Freehand Drawing System (FFDS) can infer human drawing intentions and generate the corresponding geometric primitivesand smooth B-spline curves. FFDS is a pen-based real time drawing system. On the basis of drawing position, speed, and acceleration information, FFDS establishes geometric primitives. Unintentional points areeliminated using fuzzy filtering rules. FFDS analyses the drawn curve with reference models, and obtains the corresponding possibilities. Fuzzy inference rules are used to recognize the correct model. Finally, thecorrect geometric primitives are drawn automatically.

title Constructing and consulting fuzzy decision tables
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary In this paper, we investigate a methodological issue associated with the use of decision tables (DTs). In particular, a predominant problem concerns the categorization of the condition and action states in a DT. This categorization is assumed to exhibit a discrete (or crisp) character. Although sharply defined discrete categorizations imply an. accurate and precise decision-making, in many real time problems it proves to be a too stringent and severe assumption to impose on the choice maker. In order to solve this problem, we will enhance the DT formalism to incorporate elements from the theory of fuzzy sets. The construction of a fuzzy decision table (FDT) is explained in a step-by-step manner and illustrated by means of a brief example in the field of location theory. The paper concludes with an assessment of how to use and consult a FDT.

title Algorithm for the geometric construction of an optimum shading device
source Automation in Construction 5 (3) (1996) pp. 211-217
summary Given that there is a need to shade a window from the summer sun and also a need to expose it to the winter sun, this article describes an algorithm to design automatically a geometric construct that satisfies both requirements. The construct obtained represents the minimum solution to the simultaneous requirements. The window may be described by an arbitrary convex polygon and it may be oriented in any direction, and it may be placed at any chosen latitude. The algorithm consists of two sequential steps: first to find a winter solar funnel surface; and the second to clip the surface subject to the summer shading conditions. The article introduces the design problem, illustrates the results through two examples, outlines the logic of the algorithm and includes the derivation of the mathematical relations required to implement the algorithm. This work is part of the MUSES project, which is a long term research effort to integrate Energy Consciousness with Computer Graphics in Architectural Design.

title Impact-Analysis of Urban Design Realtime impact-analysis models for urban designers
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary The past five years Prof Dr Jr T.M. de Jong, professor in environmental planning and sustainability at the Technical University of Delft, has developed a theoretical foundation for the analysis of urban design on the ecological, technical, economical, cultural and political impacts of morphologic interventions on different levels of scale. From september 1994 Jr AJ. Boelen (Urban Design Scientist and Knowledge Engineer) started a research project at the same university to further explore the possibilities of these theories and to develop impact evaluation models for urban design and development with the theoretical work of De Jong as a starting point. The paper discusses the development of a design and decision support system based on these theories. For the development of this system, techniques like object-orientation, genetic algorithms and knowledge engineering are used. The user interface, the relation between the real world, paper maps and virtual maps and the presentation of design-interventions and impacts caused by the interventions are important issues. The development-process is an interactive step by step process. It consists of the making of a prototype of the system, testing the theory and hypothe-sisses the system is based on, by applying tests end adjusting the theory and hypothesisses where needed. Eventually the system must be able to act as an integrator of many different models already developed or still to be developed. The structure of the system will allow easy future expansion and adjustment to changing insights. The logic used to develop the basic theory on which this system is founded makes it possible to even introduce and maintain rather subjective aspects like quality or appraisal as impacts that can be evaluated. In a previously developed system "Momentum" this was proved to work effectively for the national level. In this project we will - amongst other things - try to prove the effectiveness of impact-evaluation for other levels of scale.

source Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 99-113
summary A new method of describing designs by combining the paradigms of shape algebras and predicate logic representations is presented. Representing shapes and spatial relations in logic provides a natural, intuitive method of developing complete computer systems for reasoning about designs. The advantages of shape algebra formalisms over more traditional representations of geometric objects are discussed. The method employed involves the definition of a large set of high level design relations from a small set of simple structures and spatial relations. Examples in architecture and geographic information systems are illustrated.

title Modeling Designs with Shape Algebras and Formal Logic
source University of California
summary A formal, hierarchical model of shape, spatial relations and non-spatial properties is presented, constructed from first principles of geometry, topology and logic. The combination of the two major paradigms used here, shape algebras and logic, is one which has been largely unexplored. The underlying interest is the development of generalized design modeling systems in which the components may be used for a variety of synthesis and recognition problems. The algebras of shape described by Stiny have been shown to be useful in the generation and analysis of designs. The generality of their representations, their non-reliance upon predetermined structure, and their use in combination provide a richness of expression lacking in more traditional representations. The use of formal logic as a specification tool for modeling spatial relations is investigated here. Logic has proven itself useful as a programming and specification tool, providing advantages over traditional procedural programming methods. Among those is the ability to specify the knowledge to be encapsulated in a model without the need to specify data manipulation procedures. It is argued that specification in logic provides a natural method of development. The model is developed by extending the formalisms of shape algebras with the use of logic to make more precise, generalized, parametric definitions of shape and spatial relations than has been previously possible. The value of such a model is demonstrated by the use of these generalized spatial relations for solving typical problems in the fields of geographic information systems and architecture. The advantages of the representations used over more traditional 'kit-of-parts' models is also illustrated.

title Road hierarchy and speed limits in Brasília/Brazil
source H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title Computer Aided Architectural Composition by Media Experiment Design Work
source Approaches to Computer Aided Architectural Composition [ISBN 83-905377-1-0] 1996, pp. 185-201
summary There are many ways to realize computer aided compositions in architecture. In the past, many of the design methods could be characterized as Cartesian design methods, e.g. Christopher Alexander's well- known hierarchical design method presented in the early sixties. Recently, methods of artificial intelligence increased flexibility in searching for design solutions, but all these methods were still restricted by the program's logic itself. What is lacking is a means of realizing artistic possibilities intended by the designer. In view of this situation, a new approach called "media experimental design work" seems to meet designer's need. This paper begins by looking in general at experimental work in architectural design. Discussion of the theoretical background is then followed by some examples of media experimental design work, one of the current research topics in computer aided architectural design at the University of Kaiserslautern. The idea of this approach is to explore design solutions by experimental use of certain media which can evoke design associations and possibly stimulate the designer's inspirations. The use of sophisticated techniques together with the possibility of extensive manipulations can help to find outstanding design solutions. In view of their imaginative and creative power, digital media have a greater stimulating potential than traditional media in experimental design work.

In the work described here a range of architectural schemes were presented using particular representational techniques and media. An experiment was then undertaken on two different groups; architects and lay people. They were presented with a number of schemes displayed using the various techniques and media. The responses are summarised and some comments are made on the effect of computers on perceiving architecture and on communicating architectural ideas arising from an analysis of the responses.

title Spatial reasoning: improving computational efficiency
source Automation in Construction 9 (4) (2000) pp. 361-367
summary When spatial data is analysed the result is often very computer intensive: even by the standards of contemporary technologies, the machine power needed is great and the processing times significant. This is particularly so in 3-D and 4-D scenarios. What we describe here is a technique, which tackles this and associated problems. The technique is founded in the idea of quad-tesseral addressing; a technique, which was originally applied to the analysis of atomic structures. It is based on ideas concerning Hierarchical clustering developed in the 1960s and 1970s to improve data access time [G.M. Morton, A computer oriented geodetic database and a new technique on file sequencing, IBM Canada, 1996.], and on atomic isohedral (same shape) tiling strategies developed in the 1970s and 1980s concerned with group theory [B. Grunbaum, G.C. Shephard, Tilings and Patterns, Freeman, New York, 1987.]. The technique was first suggested as a suitable representation for GIS in the early 1980s when the two strands were brought together and a tesseral arithmetic applied [F.C. Holdroyd, The Geometry of Tiling Hierarchies, Ars Combanitoria 16B (1983) 211–244.; S.B.M. Bell, B.M. Diaz, F.C. Holroyd, M.J.J. Jackson, Spatially referenced methods of processing raster and vector data, Image and Vision Computing 1 (4) (1983) 211–220.; Diaz, S.B.M. Bell, Spatial Data Processing Using Tesseral Methods, Natural Environment Research Council, Swindon, 1986.]. Here, we describe how that technique can equally be applied to the analysis of environmental interaction with built forms. The way in which the technique deals with the problems described is first to linearise the three-dimensional (3-D) space being investigated. Then, the reasoning applied to that space is applied within the same environment as the definition of the problem data. We show, with an illustrative example, how the technique can be applied. The problem then remains of how to visualise the results of the analysis so undertaken. We show how this has been accomplished so that the 3-D space and the results are represented in a way which facilitates rapid interpretation of the analysis, which has been carried out.

summary This paper brings some of the debate within educational theory to bear on CAAD teaching, outlining the contributions of conservatism, critical theory, radical hermeneutics and pragmatism. The paper concludes by recommending that CAAD teaching move away from conservative concepts of teaching, design and technology to integrate it into the studio. In a highly illuminating book on education theory, Shaun Gallagher (1991) outlines four current views on education that correspond to four major positions in contemporary social theory and philosophy. I will extend these categories to a consideration of attitudes to information technology, and the teaching of computing in architecture. These four positions are conservatism, critical theory, radical hermeneutics, and pragmatism. I will show how certain issues cluster around them, how each position provides the focus of various discursive practices, or intellectual conversations in contemporary thinking, and how information technology is caught up in those conversations. These four positions are not "cognitive styles," but vigorously argued domains of debate involving writers such as Gadamer, Habermas and Derrida about the theory of interpretation. The field of interpretation is known as hermeneutics, which is concerned less with epistemology and knowledge than with understanding. Interpretation theory applies to reading texts, interpreting the law, and appreciating art, but also to the application of any practical task, such as making art, drawing, defining and solving problems, and design (Coyne and Snodgrass, 1995). Hermeneutics provides a coherent focus for considering many contemporary issues and many domains of practice. I outline what these positions in education mean in terms of CAAD (computer-aided architectural design) in the curriculum.

title A Group of Friends: The Las Americas Network, Virtual Studios, and Distance Education in Architecture
source International Journal of Architectural Computing vol. 5 - no. 3, pp. 455-468
summary This paper celebrates the human factor by describing how our collective vocation towards innovation in design education has inspired the development of an active network across the Americas. Ten years after its creation, the Las Americas Digital Research Network has generated a stream of innovative implementations. This is the first time that the main stream of these research activities is articulated into a peer-reviewed journal publication. The narrative of the paper follows a time-line that starts with the creation of the Las Americas Digital Research Network in 1996. Supported by such a framework the paper continues to describe the implementation of virtual design studios as collaborations nested at the core of the network. Finally, the paper explains how the virtual design studios provide fundamental feasibility for the development of network-mediated distance education curricula in architecture and the opening of a new dimension in the development and deployment of collaborative networks.

title Computing Assisted Drafting and Design: new technologies for old problems
source Center for the study of architecture, Bryn Mawr, Pennsylvania
summary In past issues of the Newsletter, George Tressel and I have written about virtual reality and renderings. We have each discussed particular problems with the technology, and both of us mentioned how compelling computer visualizations can be. In my article ("Virtual Reality and Rendering," February, 1995, Vol. 7, no. 4), I indicated my concerns about the quality of the scholarship and the level of detail used in making renderings or virtual worlds. Mr. Tressel (in "Visualizing the Ancient World," November, 1996, Vol. IX, no. 3) wrote about the need to distinguish between real and hypothetical parts of a visualization, the need to differentiate materials, and the difficulties involved in creating the visualizations (some of which were included in the Newsletter in black-and-white and on the Web in color). I am returning to this topic now, in part because the quality of the images available to us is improving so fast and in part because it seems now that neither Mr. Tressel nor I treated all the issues raised by the use of high-quality visualizations. The quality may be illustrated by new images of the older propylon that were created by Mr. Tressel (Figs. 1 - 3); these images are significantly more realistic than the earlier ones, but they do not represent the ultimate in quality, since they were created on a personal computer.

summary Those who build are gradually, at the moment, subverting the traditional role of the architect. Architecture needs new ways of expressing itself. Architects need new ways of being architects. There are less and less jobs, and those there are are less and less to do with Architecture. In this essay, I am concerned to confront the question of what computers mean for education and professionalism (especially in architecture), and, thus, for us as architects and teachers of computing. The argument is centred in architecture, but its conclusions are, I believe, also more generally tenable.

summary Creativity is defined in an operational manner as being associated with the new, and hence with surprise and variety. Certain qualities of various computer media (HyperMedia, Multimedia, InterNET and Virtuality) are considered in the light of this definition in order to determine how they might be shaped and used to enhance (the likelihood of) creativity, particularly in architectural design. A more thorough examination of the qualities of computational media is suggested. together with a method for carrying this out. A major consideration of CAD has been excluded since the author has, elsewhere, recently covered this aspect of computing in some depth.

summary The sphere of computing, in general, is the sphere of confusion. First, computers', thanks to (or because o) the indirect way of communicating "with" them, have not become yet the obvious and natural extension of human abilities - as TV set, radio or cars already have. It is probably because of the feeling, that they are, more or less, for specialists and that they require special knowledge or skills. In a way it is true, but surely it will change within a few years, when they become everyday tools of education at schools or just toys for children. Second, there is also the feeling or wish, that every computer is able to do everything we want - from, lets say, writing a letter, washing the dishes to very complex things as, for example, designing architecture. This is the dream of universal artificial intelligence, which should be a perfect servant, which not only listens to, but also predicts our wishes.

source Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 227-238
summary This paper is not intended as a fully researched exploration into architecture course coverage, but an attempt to introduce debate regarding some concerns on the role and status of Computing and consumer participation in the hope that CAAD peers will discuss and reflect with other specialists. A number of commentaries on serious deficiencies in the education of architects point to poor take-up of computing into the curriculum and an almost disassociation of the eventual designed building user from decisions on the design. By comparison it seems easier to find architects today who involve clients almost throughout the design process and increasing competency and continuity of CAAD usage in practices. The few brief references to Schools’ curricula are not formalised random studies. Certainly many excellent features will have been omitted. The intention is to start the debate. Finally a few directions are noted and some conclusions proffered. An argument is made for 3D CAAD models as the backbone and direct negotiating focus for design arbitration between consumer, designer [or students] and other professional collaborators in tesigning buildings, particularly where complex forms and spatial relationships are involved.

summary The popularization and wide acceptance of computer technologies is changing the position and role of CAAD in architectural education and practice. The changing profile of architectural students with respect to computing leads to a reconsideration of priorities and structure in CAAD education. These are evident in the growing acceptance of the computer as part of the standard design instrumentation and in the shift from theoretical issues to hands-on experience in CAAD courses and exercises. As such changes can only continue to occur, probably at a faster pace, CAAD has to re-evaluate its position so as to anticipate the emerging patterns of computing in architecture and design. We can distinguish between three possible outcomes. The first is decentralization of CAAD and distribution of CAAD specialists to the other specializations in architecture and building. The second is concentration on theory and methodology and use of the computer as an instrument for verifying insights and hypotheses. The third option -the worst case scenario- is degradation to a supporting role, subordinate to the designer and the theorist.

title Visualizing Global-Force Distributions in Finite-Element Models
source Journal of Architectural Engineering -- June 1996 -- Volume 2, Issue 2, pp. 71-77
summary Although computer analysis has created invaluable benefits in structural design, several structural experts have expressed concern about the impact of computers on younger engineers. Computers clearly helpdevelop insight into global-displacement patterns, but they may hinder development of insight into global-force patterns. The emergence of inexpensive computing time and automatic code checking makes itpossible to arrive at a design without assuming or investigating global-force patterns, focusing instead on member-level behavior. In the precomputer era, a designer was forced to think in terms of global-forcedistributions. However, this important design perspective will gradually disappear with the retirement of the last generation of designers educated in the precomputer era. To support this perspective in themodern design environment, the present paper introduces a computer-based tool to visualize global-force distributions in large structural systems. The tool is called the global force interpreter (GFI). This paperoutlines the approach to calculating and displaying force distributions and illustrates the tool on two example structures.
