title AN EVOLUTIONARY ARCHITECTURE
source London: Architectural Association
summary In "An Evolutionary Architecture", John Frazer presents an overview of his work for the past 30 years. Attempting to develop a theoretical basis for architecture using analogies with nature's processes of evolution and morphogenesis. Frazer's vision of the future of architecture is to construct organic buildings. Thermodynamically open systems which are more environmentally aware and sustainable physically, sociologically and economically. The range of topics which Frazer discusses is a good illustration of the breadth and depth of the evolutionary design problem. Environmental Modelling One of the first topics dealt with is the importance of environmental modelling within the design process. Frazer shows how environmental modelling is often misused or misinterpreted by architects with particular reference to solar modelling. From the discussion given it would seem that simplifications of the environmental models is the prime culprit resulting in misinterpretation and misuse. The simplifications are understandable given the amount of information needed for accurate modelling. By simplifying the model of the environmental conditions the architect is able to make informed judgments within reasonable amounts of time and effort. Unfortunately the simplications result in errors which compound and cause the resulting structures to fall short of their anticipated performance. Frazer obviously believes that the computer can be a great aid in the harnessing of environmental modelling data, providing that the same simplifying assumptions are not made and that better models and interfaces are possible. Physical Modelling Physical modelling has played an important role in Frazer's research. Leading to the construction of several novel machine readable interactive models, ranging from lego-like building blocks to beermat cellular automata and wall partitioning systems. Ultimately this line of research has led to the Universal Constructor and the Universal Interactor. The Universal Constructor The Universal Constructor features on the cover of the book. It consists of a base plug-board, called the "landscape", on top of which "smart" blocks, or cells, can be stacked vertically. The cells are individually identified and can communicate with neighbours above and below. Cells communicate with users through a bank of LEDs displaying the current state of the cell. The whole structure is machine readable and so can be interpreted by a computer. The computer can interpret the states of the cells as either colour or geometrical transformations allowing a wide range of possible interpretations. The user interacts with the computer display through direct manipulation of the cells. The computer can communicate and even direct the actions of the user through feedback with the cells to display various states. The direct manipulation of the cells encourages experimentation by the user and demonstrates basic concepts of the system. The Universal Interactor The Universal Interactor is a whole series of experimental projects investigating novel input and output devices. All of the devices speak a common binary language and so can communicate through a mediating central hub. The result is that input, from say a body-suit, can be used to drive the out of a sound system or vice versa. The Universal Interactor opens up many possibilities for expression when using a CAD system that may at first seem very strange.However, some of these feedback systems may prove superior in the hands of skilled technicians than more standard devices. Imagine how a musician might be able to devise structures by playing melodies which express the character. Of course the interpretation of input in this form poses a difficult problem which will take a great deal of research to achieve. The Universal Interactor has been used to provide environmental feedback to affect the development of evolving genetic codes. The feedback given by the Universal Interactor has been used to guide selection of individuals from a population. Adaptive Computing Frazer completes his introduction to the range of tools used in his research by giving a brief tour of adaptive computing techniques. Covering topics including cellular automata, genetic algorithms, classifier systems and artificial evolution. Cellular Automata As previously mentioned Frazer has done some work using cellular automata in both physical and simulated environments. Frazer discusses how surprisingly complex behaviour can result from the simple local rules executed by cellular automata. Cellular automata are also capable of computation, in fact able to perform any computation possible by a finite state machine. Note that this does not mean that cellular automata are capable of any general computation as this would require the construction of a Turing machine which is beyond the capabilities of a finite state machine. Genetic Algorithms Genetic algorithms were first presented by Holland and since have become a important tool for many researchers in various areas.Originally developed for problem-solving and optimization problems with clearly stated criteria and goals. Frazer fails to mention one of the most important differences between genetic algorithms and other adaptive problem-solving techniques, ie. neural networks. Genetic algorithms have the advantage that criteria can be clearly stated and controlled within the fitness function. The learning by example which neural networks rely upon does not afford this level of control over what is to be learned. Classifier Systems Holland went on to develop genetic algorithms into classifier systems. Classifier systems are more focussed upon the problem of learning appropriate responses to stimuli, than searching for solutions to problems. Classifier systems receive information from the environment and respond according to rules, or classifiers. Successful classifiers are rewarded, creating a reinforcement learning environment. Obviously, the mapping between classifier systems and the cybernetic view of organisms sensing, processing and responding to environmental stimuli is strong. It would seem that a central process similar to a classifier system would be appropriate at the core of an organic building. Learning appropriate responses to environmental conditions over time. Artificial Evolution Artificial evolution traces it's roots back to the Biomorph program which was described by Dawkins in his book "The Blind Watchmaker". Essentially, artificial evolution requires that a user supplements the standard fitness function in genetic algorithms to guide evolution. The user may provide selection pressures which are unquantifiable in a stated problem and thus provide a means for dealing ill-defined criteria. Frazer notes that solving problems with ill-defined criteria using artificial evolution seriously limits the scope of problems that can be tackled. The reliance upon user interaction in artificial evolution reduces the practical size of populations and the duration of evolutionary runs. Coding Schemes Frazer goes on to discuss the encoding of architectural designs and their subsequent evolution. Introducing two major systems, the Reptile system and the Universal State Space Modeller. Blueprint vs. Recipe Frazer points out the inadequacies of using standard "blueprint" design techniques in developing organic structures. Using a "recipe" to describe the process of constructing a building is presented as an alternative. Recipes for construction are discussed with reference to the analogous process description given by DNA to construct an organism. The Reptile System The Reptile System is an ingenious construction set capable of producing a wide range of structures using just two simple components. Frazer saw the advantages of this system for rule-based and evolutionary systems in the compactness of structure descriptions. Compactness was essential for the early computational work when computer memory and storage space was scarce. However, compact representations such as those described form very rugged fitness landscapes which are not well suited to evolutionary search techniques. Structures are created from an initial "seed" or minimal construction, for example a compact spherical structure. The seed is then manipulated using a series of processes or transformations, for example stretching, shearing or bending. The structure would grow according to the transformations applied to it. Obviously, the transformations could be a predetermined sequence of actions which would always yield the same final structure given the same initial seed. Alternatively, the series of transformations applied could be environmentally sensitive resulting in forms which were also sensitive to their location. The idea of taking a geometrical form as a seed and transforming it using a series of processes to create complex structures is similar in many ways to the early work of Latham creating large morphological charts. Latham went on to develop his ideas into the "Mutator" system which he used to create organic artworks. Generalising the Reptile System Frazer has proposed a generalised version of the Reptile System to tackle more realistic building problems. Generating the seed or minimal configuration from design requirements automatically. From this starting point (or set of starting points) solutions could be evolved using artificial evolution. Quantifiable and specific aspects of the design brief define the formal criteria which are used as a standard fitness function. Non-quantifiable criteria, including aesthetic judgments, are evaluated by the user. The proposed system would be able to learn successful strategies for satisfying both formal and user criteria. In doing so the system would become a personalised tool of the designer. A personal assistant which would be able to anticipate aesthetic judgements and other criteria by employing previously successful strategies. Ultimately, this is a similar concept to Negroponte's "Architecture Machine" which he proposed would be computer system so personalised so as to be almost unusable by other people. The Universal State Space Modeller The Universal State Space Modeller is the basis of Frazer's current work. It is a system which can be used to model any structure, hence the universal claim in it's title. The datastructure underlying the modeller is a state space of scaleless logical points, called motes. Motes are arranged in a close-packing sphere arrangement, which makes each one equidistant from it's twelve neighbours. Any point can be broken down into a self-similar tetrahedral structure of logical points. Giving the state space a fractal nature which allows modelling at many different levels at once. Each mote can be thought of as analogous to a cell in a biological organism. Every mote carries a copy of the architectural genetic code in the same way that each cell within a organism carries a copy of it's DNA. The genetic code of a mote is stored as a sequence of binary "morons" which are grouped together into spatial configurations which are interpreted as the state of the mote. The developmental process begins with a seed. The seed develops through cellular duplication according to the rules of the genetic code. In the beginning the seed develops mainly in response to the internal genetic code, but as the development progresses the environment plays a greater role. Cells communicate by passing messages to their immediate twelve neighbours. However, it can send messages directed at remote cells, without knowledge of it's spatial relationship. During the development cells take on specialised functions, including environmental sensors or producers of raw materials. The resulting system is process driven, without presupposing the existence of a construction set to use. The datastructure can be interpreted in many ways to derive various phenotypes. The resulting structure is a by-product of the cellular activity during development and in response to the environment. As such the resulting structures have much in common with living organisms which are also the emergent result or by-product of local cellular activity. Primordial Architectural Soups To conclude, Frazer presents some of the most recent work done, evolving fundamental structures using limited raw materials, an initial seed and massive feedback. Frazer proposes to go further and do away with the need for initial seed and start with a primordial soup of basic architectural concepts. The research is attempting to evolve the starting conditions and evolutionary processes without any preconditions. Is there enough time to evolve a complex system from the basic building blocks which Frazer proposes? The computational complexity of the task being embarked upon is not discussed. There is an implicit assumption that the "superb tactics" of natural selection are enough to cut through the complexity of the task. However, Kauffman has shown how self-organisation plays a major role in the early development of replicating systems which we may call alive. Natural selection requires a solid basis upon which it can act. Is the primordial soup which Frazer proposes of the correct constitution to support self-organisation? Kauffman suggests that one of the most important attributes of a primordial soup to be capable of self-organisation is the need for a complex network of catalysts and the controlling mechanisms to stop the reactions from going supracritical. Can such a network be provided of primitive architectural concepts? What does it mean to have a catalyst in this domain? Conclusion Frazer shows some interesting work both in the areas of evolutionary design and self-organising systems. It is obvious from his work that he sympathizes with the opinions put forward by Kauffman that the order found in living organisms comes from both external evolutionary pressure and internal self-organisation. His final remarks underly this by paraphrasing the words of Kauffman, that life is always to found on the edge of chaos. By the "edge of chaos" Kauffman is referring to the area within the ordered regime of a system close to the "phase transition" to chaotic behaviour. Unfortunately, Frazer does not demonstrate that the systems he has presented have the necessary qualities to derive useful order at the edge of chaos. He does not demonstrate, as Kauffman does repeatedly, that there exists a "phase transition" between ordered and chaotic regimes of his systems. He also does not make any studies of the relationship of useful forms generated by his work to phase transition regions of his systems should they exist. If we are to find an organic architecture, in more than name alone, it is surely to reside close to the phase transition of the construction system of which is it built. Only there, if we are to believe Kauffman, are we to find useful order together with environmentally sensitive and thermodynamically open systems which can approach the utility of living organisms.

title City of Bits: space, place, and the infobahn
source The MIT Press
summary Entertaining, concise, and relentlessly probing, City of Bits is a comprehensive introduction to a new type of city, a largely invisible but increasingly important system of virtual spaces interconnected by the emerging information superhighway. William Mitchell makes extensive use of concrete, practical examples and illustrations in a technically well-grounded yet accessible examination of architecture and urbanism in the context of the digital telecommunications revolution, the ongoing miniaturization of electronics, the commodification of bits, and the growing domination of software over materialized form. In seven chapters - Pulling Glass, Electronic Agoras, Cyborg Citizens, Recombinant Architecture, Soft Cities, Bit Biz, and Getting to the Good Bits - Mitchell argues that the crucial issue before us is not one of putting in place the digital plumbing of telecommunications links and associated electronic appliances, nor even of producing content for electronic delivery, but rather one of creating electronically mediated environments for the kinds of lives that we want to lead.

title The "tectonic bug" (The fall of the body in cyberspace)
source SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary Architects have been opening up onto cyberspace for more than a decade now. In terms of disciplinary issues, at stake is our ability to inhabit this new space as .designers. and not just as spectators. In the mid 90s, two theories engaged in a major confrontation. The first valued the virtual dimension of architectural space (W. J. Mitchell, City of Bits, 1995), the other valued the tectonic dimension and its constructive poiesis (K. Frampton, Studies in Tectonic Culture, 1995). Although divergent in their view of architecture.s role in the future of our technological societies, both theories revealed aspects of our relationship to the contemporary body that were, and today remain, inseparable. Where Mitchell.s book clearly intends to establish cyberspace as a new playground for architects, giving convincing examples of the programmatic mutations of modern spatiality, Kenneth Frampton.s work, Studies in Tectonic Culture, reexamines the constructive culture underlying the modern conception of space. Neither a simple history text nor a collection of technical poetry, this latter work is a manifesto developing a set of materialist ethics for the discipline of architecture. This "rappel à lordre" to resist the increasing dematerialization of architecture closes tentatively with Le Corbusier.s classic metaphor of the acrobat: The architect, he said, must not look for truth in extremes. Rather, he must struggle constantly to maintain balance. .Nobody asked him to do this. Nobody owes him any thanks. He lives in the extraordinary world of the acrobat.. Following Le Corbusier.s advice, and in consideration of current and recurrent tensions between the virtual and the tectonic, what can we say today of such a delicate equilibrium?

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.

summary Computer applications to urban design involve a distinctively rich hybrid of geometric, geographic, and annotative information. This condition raises opportunities for collaboration, needs for data integration, and examples of the increasing importance of rich datasets as a basis for design work. This paper describes these general issues, provides substantive examples from recent studio work, and demonstrates a specific implementation of software integration. The latter includes a prototypical data interface, translation tables for multimedia linkage, and capacity to work together with a web browser.

title Evolving building blocks for design using genetic engineering: A formal approach
source J.S. Gero and F. Sudweeks (eds), Advances in Formal Design Methods for CAD , IFIP-University of Sydney, Sydney, pp. 29-48
summary This paper presents a formal approach to the evolution of a representation for use in a design process. The approach adopted is based on concepts associated with genetic engineering. An initial set of genes representing elementary building blocks is evolved into a set of complex genes representing targeted building blocks. These targeted building blocks have been evolved because they are more likely to produce designs which exhibit desired characteristics than the commencing elementary building blocks. The targeted building blocks can then be used in a design process. The paper presents a formal evolutionary model of design representations based on genetic algorithms and uses pattern recognition techniques to execute aspects of the genetic engineering. The paper describes how the state space of possible designs changes over time and illustrates the model with an example from the domain of two-dimensional layouts. It concludes with a discussion of style in design.

summary This paper describes an approach to knowledge representation for an evolutionary design process. The concept of design schemas is introduced to provide the representational framework for design knowledge. Two kinds of design schemas, the design rule schema and the design gene schema, are proposed to formulate design knowledge and interpret the knowledge into genetic codes. A design problem which is used to exemplify this approach is that of a large office layout planning problem.

doi https://doi.org/10.52842/conf.ecaade.2005.787
summary Theorists in art, architecture and visual media have described the digital world as a world of mediumlessness and proclaimed that the medium of a work, once the ontological determinant for the classification of the arts, is rendered meaningless by recent technological and cultural developments (Krauss, 2000; Negroponte, 1995; Manovich, 2001). Although indebted to specific media-based techniques and their attendant ideologies, software removes the material reality of techniques to an immaterial condition where the effects of material operations are reproduced abstractly. This paper asserts that a productive approach for digital design can be found in the acknowledgement that the importance of the digital format is not that it de-materializes media, but that it allows for the maximum intermingling of media. A re-conceptualization of media follows from this, defined now as, a set of conventions derived from the material conditions of a given technical support, conventions out of which to develop a form of expressiveness that can be both projective and mnemonic (Krauss, 2000). The paper will focus on the identification of these conventions towards the development of new forms of expressiveness in architecture. Further demonstration of the intermingling of materially-based conventions is carried out in the paper through a comparative analysis of contemporary works of art and architecture, taking installation art as a particular example. A new design approach based on the maximum intermingling of media takes account of integrative strategies towards the digital and the material and sees them as inextricably linked. In the digital “medium” different sets of conventions derived from different material conditions transfer their informational assets producing fully formed, material-digital ingenuity.

summary IPER (hypertext for the knowledge of building patrimony) is the result of a research developed with C.N.R. (National Research Institute). The aim of IPER is to provide the knowledge, the description and the management of one or more historical buildings for public or private institutions. IPER allowed us to improve our methodology of building analysis, covering various disciplinary fields, in two different systems. (1.) the first one, synthetic and suitable for a group of historical buildings, (2.) the second one, complex and particularly made for monumental buildings. // This experience is related to the new regulation of teaching architecture in Italy made in 1993. The main novelty is the introduction of the laboratories with the contemporary presence of two or three teachers of different disciplines, working together with the students on the same project with different approaches. This opportunity allowed us to introduce the "knowledge engineer" as a teacher in the laboratory of building technology. IPER is given to the students with the aim of experimenting and solving the theoretical and practical difficulties that students of different years may encounter in the knowledge and representation of buildings and in the organisation of all the data from the case study.

summary The relationship between the media and architectural design can be an important factor and can influence the design outcome. However, the nature, direction and magnitude of this relationship are unknown. Consequently, there have been many speculative claims about this relationship and almost none of them are supported with empirical research studies. In order to investigate these claims and to provide a testable framework for their potential contributions to architectural education, this study aims to explore the effects of media on architectural design. During 1995-1997, a total of 90 students enrolling in First Year Design Studio and Introduction to Computing classes at Georgia Tech participated in the study. A set of quantitative measures was developed to assess the differences between the two media and the effects on the architectural design. The results suggested that media influenced certain aspects of students’ designs. It is concluded that there is a strong relationship between the media and architectural design. The type of media not only changes some quantifiable design parameters but also affects the quality of design.

source CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 209-219
summary Perspective is a method of presentation of 3- dimensional space on the 2-dimensional surface. It can only approximately express the complexity of the authentic perception of reality. During the centuries canons of presentation varied in different epochs. It is quite possible that conventions of presentation considered today as exact expressions of reality may seem for the future generations as untrue as the ancient Egypt paintings seem for us. Our mind plays the major role in all kinds of presentation. During the whole life we learn to perceive the surrounding reality. We have formed also ability to ,see" the perspective. The linear perspective is not so easy in perception without factors of colour and light. These factors play a very important role in perception of the distance. The perception of perspective is not always unmistakable. Introduction of light and shadow is one of the measures to limit the ambiguity. Objects shown in perspective with appropriately chosen colouring and light-and-shade effects reveal impression of the distance inside the flat picture. Illusions of perspective are most astonishing when one can assume deep-rooted expectations and suppositions of the addressee. The computer monitor, like the picture, has only one plane on which our project can be presented. The major feature of architecture programs is both the possibility of creating various architecture spaces and the possibility to examine how (in our opinion) the created space would affect the addressee. By means of computer programs we are able to generate drawings and objects of two kinds: first - being the ideal projection of reality (at least in the same measure as the photograph), and the second - being the total negation of perspective rules. By means of CAD programs enabling 3-dimensional job we can check how all sorts of perspective tricks and artifices affect our imagination. The program cooperates with us trying to cheat the imperfect sense of sight. The trickeries can be of various type, starting from play of lights, through the elements changing the perception of perspective, and terminating with objects totally negating the rules of sound construction of solids. The knowledge contained in these programs is an encyclopaedic recapitulation of all sorts of achievements in the field of perspective and application of colour and light effects. All that remains to the users is to exploit this tremendous variety of capabilities.

Another event that month caused fewer headlines but in retrospect was just as significant. A small company from San Francisco, Worlds Incorporated, launched WorldsChat, a three dimensional environment allowing any Internet user to don a digital costume, or avatar, and travel about and converse with other people inhabiting the space. WorldsChat was appropriately modeled on a space station complete with a central hub, hallways, sliding doors, windows, and escalators to outlying pods.

The nice thing is, most experienced OOP designers will find out they've known about patterns all along. It's just that they've never considered them as such, or tried to centralize the idea behind a given pattern so that it will be easily reusable.

title Visual semantic emergence to support creative design: A computational view
source J.S. Gero, M. L. Maher and F. Sudweeks (eds), Preprints Computational Models of Creative Design , University of Sydney, pp. 87-117
summary One computational model of creative designing involves the introduction of new variables or schemas into the designing process. This paper describes and elaborates an approach where an emergence process is used to emerge visual semantics features in a design as it proceeds. In particular visual symmetry, visual rhythm, visual movement and visual balance are emerged. The processes of emergence introduce new variables into the design process. Emergence becomes one of the computational processes capable of playing a role in creative designing.

title Architectural Design and the Architect’s Dialogue with the Computer
source CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 299-302
summary At the present time, when the problem of professional skill perfection is especially important, the designing methods perfection in order to provide "objectivization" of the form building process becomes also more and more important. The designing process analysis shows that one should not fully rely on the designer's intuition either while forming such complex organism as architectural form. But the simple thought that the appearance of some new technique results in the appearance of some new technology is not yet fully recognized. The questions of ,studying" the new technique, its "introduction" into designing practice etc. are being discussed. All this reminds one of the wide campaign once carried on to "introduce" scientific labour organization without a previous stage of this scientific organisation development which was sure to result in the discredit of the whole trend.

title On the dynamic control of a hydraulic large range robot for construction applications
source Automation in Construction 4 (1) (1995) pp. 61-73
summary There are various important outdoor applications in the fields of civil engineering, environmental technology or catastrophy management which require the introduction of a large range robot. In collaboration with industrial partners the KfK has developed such Extended Multi joint Robot (EMIR) which is driven by hydraulic actuators. The position control of EMIR is a tough problem due to the extreme nonlinearities of the kinematics and hydraulic actuators as well as the remarkable elasticities of the mechanics and hydraulics. In the first part of this paper a realistic physically transparent model of the robot will be presented. In the second part different suitable control concepts based on the model will be discussed.

title Using Virtual Models to Teach Traditional Chinese Wood Construction
source CAADRIA ‘96 [Proceedings of The First Conference on Computer Aided Architectural Design Research in Asia / ISBN 9627-75-703-9] Hong Kong (Hong Kong) 25-27 April 1996, pp. 119-130
doi https://doi.org/10.52842/conf.caadria.1996.119
summary In this paper we discuss our experience in using virtual models to teach traditional Chinese wood construction. Although our approach is technically simple – we use a kit of model parts made with the Solid Modeler of AutoCAD, Release 12 (now Release 13), and customized commands in AutoLISP – we have had excellent results. This is because of the remarkable match between the modelling medium and the highly systematized nature of traditional Chinese wood construction. It is this crucial – and interesting – characteristic that we want students to understand and appreciate. In our first teaching experience, in the fall term, 1994-95, despite unexpected drawbacks, our approach succeeded. In fact, our students, all Hong Kong Chinese, were surprisingly enthusiastic and even took pride in the sophistication of this uniquely Chinese construction system. In 1995-96, we have used the same kit of parts in two courses: an introduction to Chinese architecture (spring term) and an advanced course in Song dynasty wood construction (fall term). We first discuss briefly the theoretical basis for our approach. We then describe the assignments, the kit of parts, and supporting materials used in our teaching experiences. Finally, we discuss our findings and consider directions for the future development and improvement of our approach.

title Requirements for Virtual Design Review
source Architectural Research Quarterly 1(2), December
summary Requirements for Virtual Design Review: Fundamental Argument: This article deals primarily with the actual physical components of a virtual design review, and the difficulties associated with their integration. It is a rather refreshing approach to the problem of the virtual studio, in that it provides an empirical model of how the virtual and the real interact. Needless to say, there were numerous difficulties. 1. The reviewers and the students had to adapt to a new system of design review. Thus, traditional protocols and procedures may or may not work when dealing with a project in the virtual realm. The jurors and the students did become more comfortable as the jury progressed, but it is safe to say that those who went first most likely had a difficult and rather unhelpful session. 2. The technology itself was limited in what it could accomplish. The rate of transmissions across the line often hindered the review. Those students who used analog display, such as drawings or sketches, were not able to present these items effectively to remote viewers. The article does state that the virtual design review drew heavily upon the model of tradition review for its procedures. Was this the correct way of conducting the jury? With the introduction of technology into the process, one would think that there would be a significant shift in the model. Though the traditional model may be useful as a point of departure, we must critically engage the unique qualities that technology brings to the review. I would argue that a new model would need to be developed, whether it is a radical departure, a hybrid, or a modest adjustment to the existing model. For a traditional review, all one might need are a few push pins, a table for model display, and a surface upon which to pin his or her drawings. For the digital review, one requires monitors, computers, special lighting, video cameras, electrical outlets and phone jacks, and whatever else might be required to conduct a successful jury. It is in fact more akin to a television production than a traditional jury. The sheer complexity that technology inserts into the process can seem almost overwhelming. Yet if we can narrow our focus, find the essentials, by critically engaging those areas that will be affected by its introduction, then we can begin to imagine a true digital review.
