title Gentrification Waves in the Inner-City of Milan - A multi agent / cellular automata model based on Smith's Rent Gap theory
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 187-201
summary The aim of this paper is to investigate the gentrification process by applying an urban spatial model of gentrification, based on Smith's (1979; 1987; 1996) Rent Gap theory. The rich sociological literature on the topic mainly assumes gentrification to be a cultural phenomenon, namely the result of a demand pressure of the suburban middle and upper class, willing to return to the city (Ley, 1980; Lipton, 1977, May, 1996). Little attempt has been made to investigate and build a sound economic explanation on the causes of the process. The Rent Gap theory (RGT) of Neil Smith still represents an important contribution in this direction. At the heart of Smith's argument there is the assumption that gentrification takes place because capitals return to the inner city, creating opportunities for residential relocation and profit. This paper illustrates a dynamic model of Smith's theory through a multi-agent/ cellular automata system approach (Batty, 2005) developed on a Netlogo platform. A set of behavioural rules for each agent involved (homeowner, landlord, tenant and developer, and the passive 'dwelling' agent with their rent and level of decay) are formalised. The simulations show the surge of neighbouring degradation or renovation and population turn over, starting with different initial states of decay and estate rent values. Consistent with a Self Organized Criticality approach, the model shows that non linear interactions at local level may produce different configurations of the system at macro level. This paper represents a further development of a previous version of the model (Diappi, Bolchi, 2005). The model proposed here includes some more realistic factors inspired by the features of housing market dynamics in the city of Milan. It includes the shape of the potential rent according to city form and functions, the subdivision in areal submarkets according to the current rents, and their maintenance levels. The model has a more realistic visualisation of the city and its form, and is able to show the different dynamics of the emergent neighbourhoods in the last ten years in Milan.

title Semi-manual design support for increasing railwaystation catchment & sustainable traffic routing
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 shape ('configuration'), location and direction of the pattern of potential trips by foot or bicycle can help decision makers and designers:- the shape of such a pattern informs about the potential size of a traffic calming area(such as 30Km-zoning),- the location of such a pattern refers to the user-groups and specific destinations that a urban network should bring in safe reach for dictated groups,- the direction of such a pattern, together with shape and location, points to the best routing to raise the Sustainable Traffic Modal Split or to improve the reach of destinations like a railway-station.The patters can be generated from zip-code's of user-groups with obvious and daily destinations (school-children, rail-passengers). The next step confronts the theoretical pattern with the layout of streets and the traffic flow, mapping or listing (potential) confrontations between cars and the non-motorised modes, a basis for economical investment in traffic-safety.A design can 'model' the analysed pattern(s) to a economic, direct and safe base (cycle or pedestrian) network. In co-operation, the Dutch the traffic consultant "Verkeersadviesbureau Diepens & Okkema" in Delft, The Netherlands and the Faculty of Architecture, Delft University of Technology, in Delft, The Netherlands, develloped the semi-manual design & decision support system "STAR-Analysis"

title A digital Procedure of Building Construction: A practical project
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title The physical context of social order
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary The present ethnographic study of work settings in an established survey research center (Midwest Survey) is unique in that it combines both social organizational specifcs j4 interior physical context in contrast to previous studies that have focussed either on physical aspects or on the social dimensions of work settings. For more than four years the author observed the spatial adaptation by personnel of Midwest Survey. The dates under consideration roughly coincide with a move of Midwest Survey from an original facility to a new (and larger) set of offices. Anchored by seventy three open-ended interviews (constituing roughly 30% of the staff) the observations were carried on during and after the interviews. The synthesis of the ethnographic material revealed that physical settings act not only as a background for facilities, but they become a salient aspect of work life as indicators of status /role congruency and incongruency. Physical settings, therefore, are proposed as "extension" attributes of role structure. In doing so, Nadel's conceptualization of role structure as comprising pivotal arid peripheral attributes (1957) is amplified to include the physical setting as an "extension" attribute. Theoretical and practical implications of the study are suggested.

title Coloured Petri Nets: Basic Concepts
source 2nd ed., Springer Verlag, Berlin
summary This book presents a coherent description of the theoretical and practical aspects of Coloured Petri Nets (CP-nets or CPN). It shows how CP-nets have been developed - from being a promising theoretical model to being a full-fledged language for the design, specification, simulation, validation and implementation of large software systems (and other systems in which human beings and/or computers communicate by means of some more or less formal rules). The book contains the formal definition of CP-nets and the mathematical theory behind their analysis methods. However, it has been the intention to write the book in such a way that it also becomes attractive to readers who are more interested in applications than the underlying mathematics. This means that a large part of the book is written in a style which is closer to an engineering textbook (or a users' manual) than it is to a typical textbook in theoretical computer science. The book consists of three separate volumes. The first volume defines the net model (i.e., hierarchical CP-nets) and the basic concepts (e.g., the different behavioural properties such as deadlocks, fairness and home markings). It gives a detailed presentation of many small examples and a brief overview of some industrial applications. It introduces the formal analysis methods. Finally, it contains a description of a set of CPN tools which support the practical use of CP-nets. Most of the material in this volume is application oriented. The purpose of the volume is to teach the reader how to construct CPN models and how to analyse these by means of simulation. The second volume contains a detailed presentation of the theory behind the formal analysis methods - in particular occurrence graphs with equivalence classes and place/transition invariants. It also describes how these analysis methods are supported by computer tools. Parts of this volume are rather theoretical while other parts are application oriented. The purpose of the volume is to teach the reader how to use the formal analysis methods. This will not necessarily require a deep understanding of the underlying mathematical theory (although such knowledge will of course be a help). The third volume contains a detailed description of a selection of industrial applications. The purpose is to document the most important ideas and experiences from the projects - in a way which is useful for readers who do not yet have personal experience with the construction and analysis of large CPN diagrams. Another purpose is to demonstrate the feasibility of using CP-nets and the CPN tools for such projects. Together the three volumes present the theory behind CP-nets, the supporting CPN tools and some of the practical experiences with CP-nets and the tools. In our opinion it is extremely important that these three research areas have been developed simultaneously. The three areas influence each other and none of them could be adequately developed without the other two. As an example, we think it would have been totally impossible to develop the hierarchy concepts of CP-nets without simultaneously having a solid background in the theory of CP-nets, a good idea for a tool to support the hierarchy concepts, and a thorough knowledge of the typical application areas.

title Predicting the Past, Remembering the Future
source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 2-3
summary Charlas Magistrales 2There never has been such an exciting moment in time in the extraordinary 30 year history of our subject area, as NOW,when the philosophical theoretical and practical issues of virtuality are taking centre stage.The PastThere have, of course, been other defining moments during these exciting 30 years:• the first algorithms for generating building layouts (circa 1965).• the first use of Computer graphics for building appraisal (circa 1966).• the first integrated package for building performance appraisal (circa 1972).• the first computer generated perspective drawings (circa 1973).• the first robust drafting systems (circa 1975).• the first dynamic energy models (circa 1982).• the first photorealistic colour imaging (circa 1986).• the first animations (circa 1988)• the first multimedia systems (circa 1995), and• the first convincing demonstrations of virtual reality (circa 1996).Whereas the CAAD community has been hugely inventive in the development of ICT applications to building design, it hasbeen woefully remiss in its attempts to evaluate the contribution of those developments to the quality of the built environmentor to the efficiency of the design process. In the absence of any real evidence, one can only conjecture regarding the realbenefits which fall, it is suggested, under the following headings:• Verisimilitude: The extraordinary quality of still and animated images of the formal qualities of the interiors and exteriorsof individual buildings and of whole neighborhoods must surely give great comfort to practitioners and their clients thatwhat is intended, formally, is what will be delivered, i.e. WYSIWYG - what you see is what you get.• Sustainability: The power of «first-principle» models of the dynamic energetic behaviour of buildings in response tochanging diurnal and seasonal conditions has the potential to save millions of dollars and dramatically to reduce thedamaging environmental pollution created by badly designed and managed buildings.• Productivity: CAD is now a multi-billion dollar business which offers design decision support systems which operate,effectively, across continents, time-zones, professions and companies.• Communication: Multi-media technology - cheap to deliver but high in value - is changing the way in which we canexplain and understand the past and, envisage and anticipate the future; virtual past and virtual future!MacromyopiaThe late John Lansdown offered the view, in his wonderfully prophetic way, that ...”the future will be just like the past, onlymore so...”So what can we expect the extraordinary trajectory of our subject area to be?To have any chance of being accurate we have to have an understanding of the phenomenon of macromyopia: thephenomenon exhibitted by society of greatly exaggerating the immediate short-term impact of new technologies (particularlythe information technologies) but, more importantly, seriously underestimating their sustained long-term impacts - socially,economically and intellectually . Examples of flawed predictions regarding the the future application of information technologiesinclude:• The British Government in 1880 declined to support the idea of a national telephonic system, backed by the argumentthat there were sufficient small boys in the countryside to run with messages.• Alexander Bell was modest enough to say that: «I am not boasting or exaggerating but I believe, one day, there will bea telephone in every American city».• Tom Watson, in 1943 said: «I think there is a world market for about 5 computers».• In 1977, Ken Olssop of Digital said: «There is no reason for any individuals to have a computer in their home».The FutureJust as the ascent of woman/man-kind can be attributed to her/his capacity to discover amplifiers of the modest humancapability, so we shall discover how best to exploit our most important amplifier - that of the intellect. The more we know themore we can figure; the more we can figure the more we understand; the more we understand the more we can appraise;the more we can appraise the more we can decide; the more we can decide the more we can act; the more we can act themore we can shape; and the more we can shape, the better the chance that we can leave for future generations a trulysustainable built environment which is fit-for-purpose, cost-beneficial, environmentally friendly and culturally significactCentral to this aspiration will be our understanding of the relationship between real and virtual worlds and how to moveeffortlessly between them. We need to be able to design, from within the virtual world, environments which may be real ormay remain virtual or, perhaps, be part real and part virtual.What is certain is that the next 30 years will be every bit as exciting and challenging as the first 30 years.

title On Linguistic Aspects from a Cross-cultural Perspective
source International Conference on Generative Art
summary The goal of this paper is to discuss the issue of culture and its relationship to language and cognition by dealing with a number of lexical concepts, grammatical concepts and cultural scripts. Taking a moderate view, I reconcile universalism and ethnocentrism and argue that the study of culture-specific aspects of language has both a theoretical and practical importance. The role of universal semantic primes is obvious in culture-specific words such as the Japanese amae (a peculiarly Japanese emotion) which, though unique and untranslatable, can be accurately and intelligibly defined in terms of semantic primes (Wierzbicka, 1996). The view that meanings cannot be fully transferred from one language to another is supported by the difference in meaning manifested in the different range of use of the word happy (a common, everyday word in modern English) and joyful (a more literally and stylistically marked term.). A cross-linguistic analysis of the concept ‘happy’in English, Romanian, German, French, Italian, points to the so-called ‘traditional Anglo-Saxon distate for extreme emotions’. As far as aspects of grammar connected with culture are concerned, I compare expressive grammatical devices like intensifiers in English, Romanian and Italian. The question the paper addresses is whether constructions like syntactic reduplication(e.g. bella bella) and the absolute superlative (e.g. bellissimo) are indeed linked with what has been called ‘the theatrical quality’ of Italian life (Barzini, 1964) or not. Relative to Romanian, I assume that the idea of intensity of a state or action is conveyed, in certain registers, by terms and expressions pertaining to basic element source domains such as fire (e.g. frumoasa foc ‘fire-beautiful’) and earth (e.g. frumusetea pamantului ‘beauty of the earth’) and also by syntactic reduplication (e.g. frumoasa-frumoaselor ’beauty of the beauties’). Finally, I approach aspects of pragmatics which are culturally determined in the sense that they express cultural norms, values, ideals, attitudes. For instance, preferences are expressed directly in English while in Japanese this manner is contrary to the ideal of enryo ’restraint, reserve’.

summary At many schools of architecture the studies are directed to practical, professional use, and this fact results in different attitudes. But normally, it will be so that the longer the student goes in the study the more aspects from practice will be involved. Therefore, the studies passes from the work with the design itself and the more artistic sides to the work with planning and production. The basis of the educational progress and the professional level is research and development. Within CAD it is important that this research develops as well the theoretical foundation and includes experience in the practical use. An attitude which prioritizes the practical qualifications late in the studies has of course an effect in the CAD instruction. Tendencies to consider the computer to be a tool of drawing and visualization will dominate, and the work with structuralized information models for a general documentation has had minor interest until now, and this also includes the use of professional applications developed from different conventions in support of collaboration and quality control. The dialogue between the environment of education and research on one hand and the professional business in practice must be considered important for the developing process in the use of CAD and for the building of usable IT models. The work with "The Masonry House" and later "The Building Trade House" tries to expose how a deliberate structuralization of the CAD model early in the sketching- and planning process can support as well the more esthetic estimates as the building technology documentation. And also point out the professional qualifications bound up with 11 to be integrated in the study course.

source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary Flexibility and efficiency are two fundamental concepts in the planning of school buildings. This paper is being set to investigate the theoretical and practical links between the two. It seeks to address a number of questions: What constitutes an efficient and flexible school building? What is the optimal range and size of teaching areas to maximise flexibility? In what way can teaching areas be optimised to enhance their efficiency in use? Attempting to address these questions, an in-depth review of the relevant literature will be undertaken to analyse and refine the size of different teaching areas. Later, some operational measures of uniformity of areas and flexibility will be refined and established. These will be applied on selected school buildings to assess the their adequacy to accommodate change over use. The main outcome of this study is to provide an insight about the general rules of design for flexibility and efficiency. It also provides a framework for architects, surveyors and facilities managers to improve space efficiency in school buildings. This might enhance the process of space planning and management and improve the operational efficiency of other building types.

title Localization and comparison of two free-form surfaces
source Computer-Aided Design, Vol. 28 (12) (1996) pp. 1017-1022
summary Comparison of two free-form surfaces based on discrete data points is of paramount importance for reverse engineering. It can be used to assess the accuracy of the reconstructed surfaces and to quantify thedifference between two such surfaces. The entire process involves three main steps: data acquisition, 3D feature localization and quantitative comparison. This paper presents models and algorithms for 3D featurelocalization and quantitative comparison. Complex free-form surfaces are represented by bicubic parametric spline surfaces using discrete points. A simple yet effective pseudoinverse algorithm was developed andimplemented for localization. It consists of two iterative operations, namely, constructing a pseudo transformation matrix and point matching. A computing algorithm was developed to compare two such surfacesusing optimization techniques. Since this approach does not involve solving non-linear equations for the parameters of positions and orientations, it is fast and robust. The algorithm was implemented and testedwith several examples. It is effective and can be used in industry for sculptured surface comparison.

source Automation in Construction 5 (1) (1996) pp. 15-21
summary In this article we present several important aspects of a software system control. This is designed and developed for a wall assembly robot in an European Esprit III project called ROCCO, RObot assembly system for Computer integrated COnstruction. The system consists of an off-line program for planning of complex assembly tasks and for generating robot actions. The execution is controlled through an adaptive user interface and gives the user the possibilities to switch in an on-line mode command. All the software is designed with the object-oriented concept and implemented in C + +. The wall assembly system is organized on the base of the successive generation of different types of actions, called "Mission", "Task", and "Action". They represent different levels of assembly complexities. Those different actions are organized in a tree structure. Furthermore, the software system can be connected to a CAD-robot simulation software for checking the robot assembly motions. Added to the control system, a recovery module has been implemented for all possible errors during the construction. First the OO-model of the world and of robot activities will be presented. Secondly, several aspects of the algorithm will be explained and at the end we will show the strategy used for the robot motion.

The coming of Abstract art and modern Mathematics at the beginning of the century supposed a complete renovation of the way of understand the relationship between Mathematics and Art, reinforced by the huge expansion of computers nowadays. Chaos Theory or Fractal Geometry constitute examples of this tendencies, that normally are expressed in the two dimensional plane. The idea of this work consists on the utilisation of a series of elements from the contemporaneous Mathematics to express them in an artistic way in the three dimensional space. The result is a family of objects that we have called CYBERSCULPTURES, due to their sculptural character and the fact that they have Internet as their virtual museum.

title Artificial Life
source Boden, M. A. (1996). The Philosophy of Artificial Life, 39-94.New York and Oxford: Oxford University Press
summary Artificial Life contains a selection of articles from the first three issues of the journal of the same name, chosen so as to give an overview of the field, its connections with other disciplines, and its philosophical foundations. It is aimed at those with a general background in the sciences: some of the articles assume a mathematical background, or basic biology and computer science. I found it an informative and thought-provoking survey of a field around whose edges I have skirted for years. Many of the articles take biology as their starting point. Charles Taylor and David Jefferson provide a brief overview of the uses of artificial life as a tool in biology. Others look at more specific topics: Kristian Lindgren and Mats G. Nordahl use the iterated Prisoner's Dilemma to model cooperation and community structure in artificial ecosystems; Peter Schuster writes about molecular evolution in simplified test tube systems and its spin-off, evolutionary biotechnology; Przemyslaw Prusinkiewicz presents some examples of visual modelling of morphogenesis, illustrated with colour photographs; and Michael G. Dyer surveys different kinds of cooperative animal behaviour and some of the problems synthesising neural networks which exhibit similar behaviours. Other articles highlight the connections of artificial life with artificial intelligence. A review article by Luc Steels covers the relationship between the two fields, while another by Pattie Maes covers work on adaptive autonomous agents. Thomas S. Ray takes a synthetic approach to artificial life, with the goal of instantiating life rather than simulating it; he manages an awkward compromise between respecting the "physics and chemistry" of the digital medium and transplanting features of biological life. Kunihiko Kaneko looks to the mathematics of chaos theory to help understand the origins of complexity in evolution. In "Beyond Digital Naturalism", Walter Fontana, Guenter Wagner and Leo Buss argue that the test of artificial life is to solve conceptual problems of biology and that "there exists a logical deep structure of which carbon chemistry-based life is a manifestation"; they use lambda calculus to try and build a theory of organisation.

summary Modern research on chaos started in the 60's from an incredible finding that simple mathematical equations can model systems as complicated as waterfalls. In the 70's some scientists in the USA and in Europe started to find their way through the chaos. They were dealing with different spheres of science: mathematics, physics, biology, chemistry, physiology, ecology, economy. In the next 10 years? time the term 'chaos' has become generally known in science. Scientists gather in research groups according to their interests as to chaos and secondly according to their scientific specialities. (Gleick 1996) Objects that described chaos were irregular in shape, ripped. In 1975 Benoit Mandelbrot called them fractals. Fractal dimension that described fractal objects was also his invention. Fractal dimension is a way to measure quality: the degree of harshness, uneveness, irregularity of a given object. Carl Bovill (1996) showed how one can use fractal geometry in architecture and designing. This very fact made me try to use fractal geometry to deal with regional architecture. What or who is the degree of regionality of a given object to be for? A specially qualified person is able to state it nearly automatically. However, regionality is in some sense an unmeasurable feature. While dealing with data basis or checking particular projects, creation of procedures of automatic acquiring information concerning regionality is becoming a necessity.

summary This paper presents an approach to the analysis and description of the nature of process knowledge in architectural design, the development of a conceptual model for Galathea, a case-based navigation tool for its support, and the application of this theoretical foundation to the teaching of design to a group of about 100 second-year architecture students. Design is assumed as a globally coherent information, memory and experience-intensive process in which professional skill is the capability to govern a large number of continually evolving variables in the direction of desired change. This viewpoint on design has guided the development of Galathea, the model of a tool aimed at describing architectural design through the description, mapping and management of the complete decision-making path of projects by means of the dynamic representation of the relationship between goals, constraints and the decisions/actions adopted at specific nodes and through the creation of a case-base aimed at the storage, retrieval and adaptation of relevant design moves in similar project contexts. This conceptual model is applied to educational activity at the faculty of Architecture of Milan, with the aim of teaching how to govern a project from the outset considering it as an evolving but coherent map of design moves, which allow the adoption of the correct decisions involving the most disparate types of information, experience and memory, and which altogether conduct to the desired goal. The resolution paths of the students, all applied to the same architecture problem, result in a design move case-base, the further utilisation and interest of which is open to collegial discussion.

source Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 3-9
summary This paper describes the use of digital media in a first year undergraduate architectural design studio. It attempts to address the importance of developing a design process that is redefined by the use of computing, integrating concept and perception. Furthermore, it describes the theoretical foundations and quasi-experiments of a series of exercises developed for beginning design students.

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.

title Prototyping of Designs in Virtual Reality
source H.J.P. Timmermans (ed.), 3rd Design and Decision Support Systems in Architecture and Urban Planning Conference, Vol I: Architecture Proceedings, pp. 13-25
summary Conventional CAD systems have not yet proven their ability to provide support for activities which characterise the early conceptual phase of design. We propose to refer to this set of capabilities of the human designer in conventional design as, design prototyping. We define the theoretical limitations of current CAD systems for supporting design prototyping, and postulate the potential of functionally dedicated, task related, CAD modules in Virtual Reality as a means to provide a unique form of a knowledgebased, visual design support environment for design prototyping support. We are currently engaged in a research program in which we explore CAD as a medium to support early conceptual design through rapid prototyping of architectural form. Furthermore we are exploring Virtual Reality as a potential design prototyping environment in which prototypes of designs can be constructed, communicated and visually evaluated at a high level of verisimilitude. In the first phase we have built the prototype system VIDE. This system has been used for extensive internal evaluation. In the ongoing second phase we are constructing an empirical research to observe designers at work on design prototyping in the Virtual Reality environment.
