title Sustaining Studio Culture: How Well Do Internet Tools Meet the Needs of Virtual Design Studios?

summary The Internet beckons seductively to students. The prospect of nearly instantaneous communication with acquaintances spread across the face of the earth is alluring. The ease with which rich graphical content can be made available to the world is stunning. The possibility of a design being seen by friends, family, and famous architects is tantalizing. Faculty are drawn by the potent synergy and learning that can be found in the opposition and cooperation of different cultural roots. It is probable that entire design studio sequences will be offered through distance-learning programs in the near future. Is that a good idea? Much has been written about "virtual design studios" in architecture schools and "virtual offices" in practice. Most offices have largely or totally abandoned drafting boards in favor of digital tools of production. Yet, regarding design, Ken Sanders, author of The Digital Architect, and Manager of Information Services at Zimmer Gunsul Frasca Partnership (ZGF), of Portland, Oregon, has written "we still make an effort to locate project teams together and always will". Production CAD work requires different kinds of interaction than design and design instruction. The experiments have been invaluable in developing strategies for use of the Internet as a component of a design studio series, but rarely depend entirely on use of the Internet for all course communications. In fact, most describe fairly isolated efforts to augment some aspect of traditional design environments using Internet tools (ftp, email, web). A few have implemented new pedagogic or collaboration paradigms (e.g., ETH’s phase(x)). This paper considers the traditional design studio in terms of formal and informal activities, characterizes the major Internet technologies with regard to the resulting interaction issues. In particular, it describes an area of informal work group communications that appears to be ill-supported with existing tools. The paper goes on to describe a web-based collaboration tool which was developed to address the need for less formal communication. The context for this development is the concept of a fully distributed collaboration environment with particular attention to questions of informal communication. Finally, it describes how the tool was deployed in an experimental "web studio" setting and student responses to use of the tool.

title The E-Talier: Inter-university Networked Design Studios
doi https://doi.org/10.52842/conf.ecaade.2000.045
source Promise and Reality: State of the Art versus State of Practice in Computing for the Design and Planning Process [18th eCAADe Conference Proceedings / ISBN 0-9523687-6-5] Weimar (Germany) 22-24 June 2000, pp. 45-50
summary The widespread infiltration of internet based variations of traditional areas of society (e-commerce, e-business, e-mail etc.) will not spare the halls of academia in its propagation. The term courseware is well nigh 20 years old and considerable research and development has been done in bringing network based distributed courses to university consortiums including those in architecture and civil engineering. Indeed, the European Commission has recently approved funding for a 3-year web-based virtual university of architecture and construction technology: the WINDS project led by the University of Ancona. Such attempts to create e-courses are largely an extension of typical courseware where the syllabus is quantified and divided into lessons for use by the students alone or in conjunction with their tutors and professors. This is quite adequate in conveying the base knowledge of the profession. However, the tenants of being an architect or engineer involve the deft use of that unwieldy named and deliciously imprecise tool called "design". Teaching design sooner or later involves the design studio: a pedagogically construed environment of simulation intended to train, not teach the skills of designing. This is fundamentally different from normal courseware. A network based design studio (Etalier) must be able to reflect the nature of learning design. Design studios typically involve specifically chosen design problems, researched supporting information to assist design decisions, focussed discussions, individual consultation and criticism, group criticism, public forums for presentation discussion and criticism as well as a myriad of informal undocumented communication among the students themselves. So too must an Etalier function. Essentially, it must allow collaboration through communication. Traditional barriers to collaboration include language, culture (both national and professional) and distance. Through the internet's capricious growth and the widespread use of English as a second language, the largest hurdle to attaining fruitful collaboration is probably cultural. In the case of an Etalier in a university setting, the cultural difficulties arise from administrative rules, the pedagogical culture of specific universities and issues such as scheduling and accreditation. Previous experiments with virtual design studios have demonstrated the criticality of such issues. The proposed system allows participating members to specify the degree and breadth with which they wish to partake. As opposed to specifying the conditions of membership, we propose to specify the conditions of partnership. Through the basic principal of reciprocity, issues such as accreditation and work load sharing can be mitigated. Further, the establishment of a studio market will allow students, tutors and professors from participating institutions to partake in studio projects of their choosing in accordance with their own constraints, be they related to schedule, expertise, legal or other matters. The paper describes these mechanisms and some possible scenarios for collaboration in the Etalier market.

title Bridging GIS-based landscape analysis/modelling and 3D-simulation.Is this already 4D?
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary Several studies have used remote sensing to map patterns of e.g. deforestation or to analyse the rates of land use change. Thesestudies have proven useful for interpreting the causes of urbanization, deforestation etc. and the impact of such changes on theregion. Monitoring of change (e.g. deforestation or reforestation) is frequently perceived as one of the most important contributionsof remote sensing technology to the study of global ecological and environmental change (Roughgarden et al. 1991). Manyresearchers believe that the integration of remote sensing techniques within analysis of environmental change is essential if ecologistsare to meet the challenges of the future, specifically issues relating to global change; however, in practice, this integration has so farbeen limited (Griffiths & Mather 2000). Considerable difficulties are encountered in linking, on the one hand, the biologies oforganisms and the ecologies of populations to the fluxes of material and energy quantifiable at the level of ecosystems. In this paper,we concentrate on the methodological aspects of the delineation of landscape objects and touch the ecological application onlysuperficially but we elucidate the potential of the proposed methodology for several ecological applications briefly.

title The e-learning action plan: designing tomorrow’s education
source Communication from the Commission to the Council and the EuropeanParliament, COM(2001) 172 final, 28 March 2001
summary The "eLearning: Designing tomorrow's education" initiative1 was adopted by the European Commission on 24 May 2000. Following up the conclusions of the Lisbon European Council, it set out the principles, objectives and lines of action of eLearning, defined as the use of new multimedia technologies and the Internet to improve the quality of learning by facilitating access to resources and services as well as remote exchanges and collaboration. The eLearning initiative was welcomed by the Ministers of Education and by the Feira European Council in June 2000. The eLearning initiative is part of the comprehensive eEurope Action Plan2, the aim of which is to allow Europe to exploit its strengths and overcome the barriers holding back the uptake of digital technologies. It also falls in with the Report on the concrete future objectives of education systems3 by adopting information and communication technology development as one of its objectives. The effectiveness of education systems depends entirely on the effectiveness of the approaches to teaching and learning. In order to be effective, the introduction of information and communication technologies will have to be accompanied by a far-reaching reorganisation of learning structures. The eLearning initiative is also of relevance for the candidate countries given the interest they have shown for the eEurope action plan.

summary New Technologies (NTs) offer us tools with which to deal with the new challenges that a changing society or workplace presents. In particular, new design strategies and approaches are required by the emerging Information Society, and NTs offer effective solutions to the designers in the different stages of their professional life, and in different working situations. In this paper some meaningful scenarios of the use of the NTs in Architecture and Urban Design are introduced; the scenarios have been selected in order to understand how the role of architects in the Information Society is changing, and what new opportunities NTs offer them. It will be underlined how the telematic networks play an essential role in the activation of virtual studios that are able to compete in an increasingly global market; examples will be given of the use of the Web to support activities related to Urban Planning and Management; it will be shown how the Internet may be used to access strategic resources for education and training, and sustain lifelong learning. The aforesaid considerations derive from a Web-Based Instruction system we have developed to support University students in the definition of projects that can concern either single buildings or whole parts of a city. The system can easily be adopted in the other scenarios introduced.

summary The expanding use of computers in developing countries - alongside the results of surveys revealing dramatic social indicators for illiteracy - demands careful analysis of the necessary education and training for people to be able to take part and to survive in the information society.”For a citizen of international society, it is no longer enough to know how to read and write, or to have learned a skill. One must have access to information, know how to look for it and find it, master the usage, organize it, understand its organizational forms and, above all, make appropriate, adequate and effective use of it. “ (Spitz, 2000). In this article we raise issues concerning the use of the Internet by low-income classes in Brazil, aiming at discussing the fundamental role Design plays in terms of the inclusion of people from these classes in the inter-connected society.

summary We will analyze a pedagogic exercise that joined together both the Informatics and Morphology Courses, required in the second year of Architecture School. The objective of the analysis is to explore the possibilities of the computer as a tool for design, and also to contribute some ideas for planning, curriculum development, and the necessary training to introduce the use of computer graphics in the Architecture School. We based our analysis on some preliminary hypotheses: (1) Students must learn to use digital models with a certain degree of simultaneity with learning design and the other techniques used to develop models. (2) Professors of Design, Representation, and Morphology are main actors in this learning process; they do not have to become experts in informatics, but have some understanding of the topic. (3) Many universities and professional associations are offering students and professionals courses based in the use of programs, instead of addressing their real needs.

title Possible Futures in Computer Art Generation
source International Conference on Generative Art
summary Years of trying to create an "Image Idea Generator" program have convinced me that the perfect solution would be to have an artificial artistic person, a design slave. This paper describes how I came to that conclusion, realistic alternatives, and briefly, how it could possibly happen. 1. The history of Repligator and Gliftic 1.1 Repligator In 1996 I had the idea of creating an “image idea generator”. I wanted something which would create images out of nothing, but guided by the user. The biggest conceptual problem I had was “out of nothing”. What does that mean? So I put aside that problem and forced the user to give the program a starting image. This program eventually turned into Repligator, commercially described as an “easy to use graphical effects program”, but actually, to my mind, an Image Idea Generator. The first release came out in October 1997. In December 1998 I described Repligator V4 [1] and how I thought it could be developed away from simply being an effects program. In July 1999 Repligator V4 won the Shareware Industry Awards Foundation prize for "Best Graphics Program of 1999". Prize winners are never told why they won, but I am sure that it was because of two things: 1) Easy of use 2) Ease of experimentation "Ease of experimentation" means that Repligator does in fact come up with new graphics ideas. Once you have input your original image you can generate new versions of that image simply by pushing a single key. Repligator is currently at version 6, but, apart from adding many new effects and a few new features, is basically the same program as version 4. Following on from the ideas in [1] I started to develop Gliftic, which is closer to my original thoughts of an image idea generator which "starts from nothing". The Gliftic model of images was that they are composed of three components: 1. Layout or form, for example the outline of a mandala is a form. 2. Color scheme, for example colors selected from autumn leaves from an oak tree. 3. Interpretation, for example Van Gogh would paint a mandala with oak tree colors in a different way to Andy Warhol. There is a Van Gogh interpretation and an Andy Warhol interpretation. Further I wanted to be able to genetically breed images, for example crossing two layouts to produce a child layout. And the same with interpretations and color schemes. If I could achieve this then the program would be very powerful. 1.2 Getting to Gliftic Programming has an amazing way of crystalising ideas. If you want to put an idea into practice via a computer program you really have to understand the idea not only globally, but just as importantly, in detail. You have to make hard design decisions, there can be no vagueness, and so implementing what I had decribed above turned out to be a considerable challenge. I soon found out that the hardest thing to do would be the breeding of forms. What are the "genes" of a form? What are the genes of a circle, say, and how do they compare to the genes of the outline of the UK? I wanted the genotype representation (inside the computer program's data) to be directly linked to the phenotype representation (on the computer screen). This seemed to be the best way of making sure that bred-forms would bare some visual relationship to their parents. I also wanted symmetry to be preserved. For example if two symmetrical objects were bred then their children should be symmetrical. I decided to represent shapes as simply closed polygonal shapes, and the "genes" of these shapes were simply the list of points defining the polygon. Thus a circle would have to be represented by a regular polygon of, say, 100 sides. The outline of the UK could easily be represented as a list of points every 10 Kilometers along the coast line. Now for the important question: what do you get when you cross a circle with the outline of the UK? I tried various ways of combining the "genes" (i.e. coordinates) of the shapes, but none of them really ended up producing interesting shapes. And of the methods I used, many of them, applied over several "generations" simply resulted in amorphous blobs, with no distinct family characteristics. Or rather maybe I should say that no single method of breeding shapes gave decent results for all types of images. Figure 1 shows an example of breeding a mandala with 6 regular polygons: Figure 1 Mandala bred with array of regular polygons I did not try out all my ideas, and maybe in the future I will return to the problem, but it was clear to me that it is a non-trivial problem. And if the breeding of shapes is a non-trivial problem, then what about the breeding of interpretations? I abandoned the genetic (breeding) model of generating designs but retained the idea of the three components (form, color scheme, interpretation). 1.3 Gliftic today Gliftic Version 1.0 was released in May 2000. It allows the user to change a form, a color scheme and an interpretation. The user can experiment with combining different components together and can thus home in on an personally pleasing image. Just as in Repligator, pushing the F7 key make the program choose all the options. Unlike Repligator however the user can also easily experiment with the form (only) by pushing F4, the color scheme (only) by pushing F5 and the interpretation (only) by pushing F6. Figures 2, 3 and 4 show some example images created by Gliftic. Figure 2 Mandala interpreted with arabesques   Figure 3 Trellis interpreted with "graphic ivy"   Figure 4 Regular dots interpreted as "sparks" 1.4 Forms in Gliftic V1 Forms are simply collections of graphics primitives (points, lines, ellipses and polygons). The program generates these collections according to the user's instructions. Currently the forms are: Mandala, Regular Polygon, Random Dots, Random Sticks, Random Shapes, Grid Of Polygons, Trellis, Flying Leap, Sticks And Waves, Spoked Wheel, Biological Growth, Chequer Squares, Regular Dots, Single Line, Paisley, Random Circles, Chevrons. 1.5 Color Schemes in Gliftic V1 When combining a form with an interpretation (described later) the program needs to know what colors it can use. The range of colors is called a color scheme. Gliftic has three color scheme types: 1. Random colors: Colors for the various parts of the image are chosen purely at random. 2. Hue Saturation Value (HSV) colors: The user can choose the main hue (e.g. red or yellow), the saturation (purity) of the color scheme and the value (brightness/darkness) . The user also has to choose how much variation is allowed in the color scheme. A wide variation allows the various colors of the final image to depart a long way from the HSV settings. A smaller variation results in the final image using almost a single color. 3. Colors chosen from an image: The user can choose an image (for example a JPG file of a famous painting, or a digital photograph he took while on holiday in Greece) and Gliftic will select colors from that image. Only colors from the selected image will appear in the output image. 1.6 Interpretations in Gliftic V1 Interpretation in Gliftic is best decribed with a few examples. A pure geometric line could be interpreted as: 1) the branch of a tree 2) a long thin arabesque 3) a sequence of disks 4) a chain, 5) a row of diamonds. An pure geometric ellipse could be interpreted as 1) a lake, 2) a planet, 3) an eye. Gliftic V1 has the following interpretations: Standard, Circles, Flying Leap, Graphic Ivy, Diamond Bar, Sparkz, Ess Disk, Ribbons, George Haite, Arabesque, ZigZag. 1.7 Applications of Gliftic Currently Gliftic is mostly used for creating WEB graphics, often backgrounds as it has an option to enable "tiling" of the generated images. There is also a possibility that it will be used in the custom textile business sometime within the next year or two. The real application of Gliftic is that of generating new graphics ideas, and I suspect that, like Repligator, many users will only understand this later. 2. The future of Gliftic, 3 possibilties Completing Gliftic V1 gave me the experience to understand what problems and opportunities there will be in future development of the program. Here I divide my many ideas into three oversimplified possibilities, and the real result may be a mix of two or all three of them. 2.1 Continue the current development "linearly" Gliftic could grow simply by the addition of more forms and interpretations. In fact I am sure that initially it will grow like this. However this limits the possibilities to what is inside the program itself. These limits can be mitigated by allowing the user to add forms (as vector files). The user can already add color schemes (as images). The biggest problem with leaving the program in its current state is that there is no easy way to add interpretations. 2.2 Allow the artist to program Gliftic It would be interesting to add a language to Gliftic which allows the user to program his own form generators and interpreters. In this way Gliftic becomes a "platform" for the development of dynamic graphics styles by the artist. The advantage of not having to deal with the complexities of Windows programming could attract the more adventurous artists and designers. The choice of programming language of course needs to take into account the fact that the "programmer" is probably not be an expert computer scientist. I have seen how LISP (an not exactly easy artificial intelligence language) has become very popular among non programming users of AutoCAD. If, to complete a job which you do manually and repeatedly, you can write a LISP macro of only 5 lines, then you may be tempted to learn enough LISP to write those 5 lines. Imagine also the ability to publish (and/or sell) "style generators". An artist could develop a particular interpretation function, it creates images of a given character which others find appealing. The interpretation (which runs inside Gliftic as a routine) could be offered to interior designers (for example) to unify carpets, wallpaper, furniture coverings for single projects. As Adrian Ward [3] says on his WEB site: "Programming is no less an artform than painting is a technical process." Learning a computer language to create a single image is overkill and impractical. Learning a computer language to create your own artistic style which generates an infinite series of images in that style may well be attractive. 2.3 Add an artificial conciousness to Gliftic This is a wild science fiction idea which comes into my head regularly. Gliftic manages to surprise the users with the images it makes, but, currently, is limited by what gets programmed into it or by pure chance. How about adding a real artifical conciousness to the program? Creating an intelligent artificial designer? According to Igor Aleksander [1] conciousness is required for programs (computers) to really become usefully intelligent. Aleksander thinks that "the line has been drawn under the philosophical discussion of conciousness, and the way is open to sound scientific investigation". Without going into the details, and with great over-simplification, there are roughly two sorts of artificial intelligence: 1) Programmed intelligence, where, to all intents and purposes, the programmer is the "intelligence". The program may perform well (but often, in practice, doesn't) and any learning which is done is simply statistical and pre-programmed. There is no way that this type of program could become concious. 2) Neural network intelligence, where the programs are based roughly on a simple model of the brain, and the network learns how to do specific tasks. It is this sort of program which, according to Aleksander, could, in the future, become concious, and thus usefully intelligent. What could the advantages of an artificial artist be? 1) There would be no need for programming. Presumbably the human artist would dialog with the artificial artist, directing its development. 2) The artificial artist could be used as an apprentice, doing the "drudge" work of art, which needs intelligence, but is, anyway, monotonous for the human artist. 3) The human artist imagines "concepts", the artificial artist makes them concrete. 4) An concious artificial artist may come up with ideas of its own. Is this science fiction? Arthur C. Clarke's 1st Law: "If a famous scientist says that something can be done, then he is in all probability correct. If a famous scientist says that something cannot be done, then he is in all probability wrong". Arthur C Clarke's 2nd Law: "Only by trying to go beyond the current limits can you find out what the real limits are." One of Bertrand Russell's 10 commandments: "Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric" 3. References 1. "From Ramon Llull to Image Idea Generation".

title Computational Situated Learning in Designing - Application to Architectural Shape Semantics
source The University of Sydney, Faculty of Architecture
summary Learning the situatedness (applicability conditions), of design knowledge recognised from design compositions is the central tenet of the research presented in this thesis. This thesis develops and implements a computational system of situated learning and investigates its utility in designing. Situated learning is based on the concept that "knowledge is contextually situated and is fundamentally influenced by its situation". In this sense learning is tuned to the situations within which "what you do when you do matters". Designing cannot be predicted and the results of designing are not based on actions independent of what is being designed or independent of when, where and how it was designed. Designers' actions are situation dependent (situated), such that designers work actively with the design environment within the specific conditions of the situation where neither the goal state nor the solution space is completely predetermined. In designing, design solutions are fluid and emergent entities generated by dynamic and situated activities instead of fixed design plans. Since it is not possible in advance to know what knowledge to use in relation to any situation we need to learn knowledge in relation to its situation, i.e. learn the applicability conditions of knowledge. This leads towards the notion of the situation as having the potential role of guiding the use of knowledge.

Situated Learning in Designing (SLiDe) is developed and implemented within the domain of architectural shape composition (in the form of floor plans), to construct the situatedness of shape semantics. An architectural shape semantic is a set of characteristics with a semantic meaning based on a particular view of a shape such as reflection symmetry, adjacency, rotation and linearity. Each shape semantic has preconditions without which it cannot be recognised. Such preconditions indicate nothing about the situation within which this shape semantic was recognised. The situatedness or the applicability conditions of a shape semantic is viewed as, the interdependent relationships between this shape semantic as the design knowledge in focus, and other shape semantics across the observations of a design composition. While designing, various shape semantics and relationships among them emerge in different representations of a design composition. Multiple representations of a design composition by re-interpretation have been proposed to serve as a platform for SLiDe. Multiple representations provide the opportunity for different shape semantics and relationships among them to be found from a single design composition. This is important if these relationships are to be used later because it is not known in advance which of the possible relationships could be constructed are likely to be useful. Hence, multiple representations provide a platform for different situations to be encountered. A symbolic representation of shape and shape semantics is used in which the infinite maximal lines form the representative primitives of the shape.

SLiDe is concerned with learning the applicability conditions (situatedness), of shape semantics locating them in relation to situations within which they were recognised (situation dependent), and updating the situatedness of shape semantics in response to new observations of the design composition. SLiDe consists of three primary modules: Generator, Recogniser and Incremental Situator. The Generator is used by the designer to develop a set of multiple representations of a design composition. This set of representations forms the initial design environment of SLiDe. The Recogniser detects shape semantics in each representation and produces a set of observations, each of which is comprised of a group of shape semantics recognised at each corresponding representation. The Incremental Situator module consists of two sub-modules, Situator and Restructuring Situator, and utilises an unsupervised incremental clustering mechanism not affected by concept drift. The Situator module locates recognised shape semantics in relation to their situations by finding regularities of relationships among them across observations of a design composition and clustering them into situational categories organised in a hierarchical tree structure. Such relationships change over time due to the changes taken place in the design environment whenever further representations are developed using the Generator module and new observations are constructed by the Recogniser module. The Restructuring Situator module updates previously learned situational categories and restructures the hierarchical tree accordingly in response to new observations.

Learning the situatedness shape semantics may play a crucial role in designing if designers pursue further some of these shape semantics. This thesis illustrates an approach in which SLiDe can be utilised in designing to explore the shapes in a design composition in various ways; bring designers! attention to potentially hidden features and shape semantics of their designs; and maintain the integrity of the design composition by using the situatedness of shape semantics. The thesis concludes by outlining future directions for this research to learn and update the situatedness of design knowledge within the context of use; considering the role of functional knowledge while learning the situatedness of design knowledge; and developing an autonomous situated agent-based designing system.

title Artificial Intelligence: A Modern Approach
source Prentice Hall, Englewood Cliffs, NJ
summary Humankind has given itself the scientific name homo sapiens--man the wise--because our mental capacities are so important to our everyday lives and our sense of self. The field of artificial intelligence, or AI, attempts to understand intelligent entities. Thus, one reason to study it is to learn more about ourselves. But unlike philosophy and psychology, which are also concerned with AI strives to build intelligent entities as well as understand them. Another reason to study AI is that these constructed intelligent entities are interesting and useful in their own right. AI has produced many significant and impressive products even at this early stage in its development. Although no one can predict the future in detail, it is clear that computers with human-level intelligence (or better) would have a huge impact on our everyday lives and on the future course of civilization. AI addresses one of the ultimate puzzles. How is it possible for a slow, tiny brain{brain}, whether biological or electronic, to perceive, understand, predict, and manipulate a world far larger and more complicated than itself? How do we go about making something with those properties? These are hard questions, but unlike the search for faster-than-light travel or an antigravity device, the researcher in AI has solid evidence that the quest is possible. All the researcher has to do is look in the mirror to see an example of an intelligent system. AI is one of the newest disciplines. It was formally initiated in 1956, when the name was coined, although at that point work had been under way for about five years. Along with modern genetics, it is regularly cited as the ``field I would most like to be in'' by scientists in other disciplines. A student in physics might reasonably feel that all the good ideas have already been taken by Galileo, Newton, Einstein, and the rest, and that it takes many years of study before one can contribute new ideas. AI, on the other hand, still has openings for a full-time Einstein. The study of intelligence is also one of the oldest disciplines. For over 2000 years, philosophers have tried to understand how seeing, learning, remembering, and reasoning could, or should, be done. The advent of usable computers in the early 1950s turned the learned but armchair speculation concerning these mental faculties into a real experimental and theoretical discipline. Many felt that the new ``Electronic Super-Brains'' had unlimited potential for intelligence. ``Faster Than Einstein'' was a typical headline. But as well as providing a vehicle for creating artificially intelligent entities, the computer provides a tool for testing theories of intelligence, and many theories failed to withstand the test--a case of ``out of the armchair, into the fire.'' AI has turned out to be more difficult than many at first imagined, and modern ideas are much richer, more subtle, and more interesting as a result. AI currently encompasses a huge variety of subfields, from general-purpose areas such as perception and logical reasoning, to specific tasks such as playing chess, proving mathematical theorems, writing poetry{poetry}, and diagnosing diseases. Often, scientists in other fields move gradually into artificial intelligence, where they find the tools and vocabulary to systematize and automate the intellectual tasks on which they have been working all their lives. Similarly, workers in AI can choose to apply their methods to any area of human intellectual endeavor. In this sense, it is truly a universal field.

title Data Mining - Practical Machine Learning Tools and Techniques with JAVA Implementations
source Morgan Kaufmann
summary Witten and Frank's textbook was one of two books that I used for a data mining class in the Fall of 2001. The book covers all major methods of data mining that produce a knowledge representation as output. Knowledge representation is hereby understood as a representation that can be studied, understood, and interpreted by human beings, at least in principle. Thus, neural networks and genetic algorithms are excluded from the topics of this textbook. We need to say "can be understood in principle" because a large decision tree or a large rule set may be as hard to interpret as a neural network. The book first develops the basic machine learning and data mining methods. These include decision trees, classification and association rules, support vector machines, instance-based learning, Naive Bayes classifiers, clustering, and numeric prediction based on linear regression, regression trees, and model trees. It then goes deeper into evaluation and implementation issues. Next it moves on to deeper coverage of issues such as attribute selection, discretization, data cleansing, and combinations of multiple models (bagging, boosting, and stacking). The final chapter deals with advanced topics such as visual machine learning, text mining, and Web mining.

title Some Phenomena of Spatial Characteristics of Cyberspace

summary "Space," which has long been an important concept in architecture (Bloomer & Moore, 1977; Mitchell, 1995, 1999), has attracted interest of researchers from various academic disciplines in recent years (Agnew, 1993; Benko & Strohmayer, 1996; Chang, 1999; Foucault, 1982; Gould, 1998). Researchers from disciplines such as anthropology, geography, sociology, philosophy, and linguistics regard it as the basis of the discussion of various theories in social sciences and humanities (Chen, 1999). On the other hand, since the invention of Internet, Internet users have been experiencing a new and magic "world." According to the definitions in traditional architecture theories, "space" is generated whenever people define a finite void by some physical elements (Zevi, 1985). However, although Internet is a virtual, immense, invisible and intangible world, navigating in it, we can still sense the very presence of ourselves and others in a wonderland. This sense could be testified by our naming of Internet as Cyberspace -- an exotic kind of space. Therefore, as people nowadays rely more and more on the Internet in their daily life, and as more and more architectural scholars and designers begin to invest their efforts in the design of virtual places online (e.g., Maher, 1999; Li & Maher, 2000), we cannot help but ask whether there are indeed sensible spaces in Internet. And if yes, these spaces exist in terms of what forms and created by what ways?To join the current interdisciplinary discussion on the issue of space, and to obtain new definition as well as insightful understanding of "space", this study explores the spatial phenomena in Internet. We hope that our findings would ultimately be also useful for contemporary architectural designers and scholars in their designs in the real world.As a preliminary exploration, the main objective of this study is to discover the elements involved in the creation/construction of Internet spaces and to examine the relationship between human participants and Internet spaces. In addition, this study also attempts to investigate whether participants from different academic disciplines define or experience Internet spaces in different ways, and to find what spatial elements of Internet they emphasize the most.In order to achieve a more comprehensive understanding of the spatial phenomena in Internet and to overcome the subjectivity of the members of the research team, the research design of this study was divided into two stages. At the first stage, we conducted literature review to study existing theories of space (which are based on observations and investigations of the physical world). At the second stage of this study, we recruited 8 Internet regular users to approach this topic from different point of views, and to see whether people with different academic training would define and experience Internet spaces differently.The results of this study reveal that the relationship between human participants and Internet spaces is different from that between human participants and physical spaces. In the physical world, physical elements of space must be established first; it then begins to be regarded as a place after interaction between/among human participants or interaction between human participants and the physical environment. In contrast, in Internet, a sense of place is first created through human interactions (or activities), Internet participants then begin to sense the existence of a space. Therefore, it seems that, among the many spatial elements of Internet we found, "interaction/reciprocity" Ñ either between/among human participants or between human participants and the computer interface Ð seems to be the most crucial element.In addition, another interesting result of this study is that verbal (linguistic) elements could provoke a sense of space in a degree higher than 2D visual representation and no less than 3D visual simulations. Nevertheless, verbal and 3D visual elements seem to work in different ways in terms of cognitive behaviors: Verbal elements provoke visual imagery and other sensory perceptions by "imagining" and then excite personal experiences of space; visual elements, on the other hand, provoke and excite visual experiences of space directly by "mapping".Finally, it was found that participants with different academic training did experience and define space differently. For example, when experiencing and analyzing Internet spaces, architecture designers, the creators of the physical world, emphasize the design of circulation and orientation, while participants with linguistics training focus more on subtle language usage. Visual designers tend to analyze the graphical elements of virtual spaces based on traditional painting theories; industrial designers, on the other hand, tend to treat these spaces as industrial products, emphasizing concept of user-center and the control of the computer interface.The findings of this study seem to add new information to our understanding of virtual space. It would be interesting for future studies to investigate how this information influences architectural designers in their real-world practices in this digital age. In addition, to obtain a fuller picture of Internet space, further research is needed to study the same issue by examining more Internet participants who have no formal linguistics and graphical training.

summary Perforated solar screens (PSS) are broadly adopted, providing obvious control over daylight, and also affecting heating and cooling loads. In this paper, a parametric information model is proposed for analyzing daylight of unit offices with PSS, aiming to ascertain the impact exerted by PSS design variables on daylighting, i.e. perforation size, porosity, overhanging distance and perforation width/height ratio. As the results uncover, in comparison to cases of no shading, PSS can reduce overlighting possibility and increase quantity of useful daylight percentage in the near and middle zones of room, but decrease illuminance in the far zone. Porosity is the factor of most significance with UDI100-2000 inclining maximally by 65%. Overhanging distance and width/height ratio rank behind and larger overhanging distance and ratio at 1 are recommend with more useful daylight in the maximum range. Perforation size is of the least importance.

summary Architects are visual learners. The Internet has enabled interactive learning tools that can be used to assist in visual thinking of structural concepts, especially at the introductory levels. Here, we propose a visual approach for understanding structures through a series of interactive learning modules, or ’gizmos’. These gizmos, are the tools that the student may use to examine one structural concept at a time. Being interactive, they offer many more possibilities beyond what one static problem can show. The approach aims to enhance students’ visual intuition, and hence understanding of structural concepts and the parameters affecting design. This paper will present selected structural gizmos, how they work, and how they can enhance structural education for architects.

summary Ever-increasing complexity in product design and the need to deliver a cost-effective solution that benefits from a dynamic approach requires the employment and adoption of innovative design methods which ensure that products are of the highest quality and meet or exceed customers' expectations. According to Bronowski (1976) science and art were originally two faces of the same human creativity. However, as civilisation advances and works became specialised, the dichotomy of science and art gradually became apparent. Hence scientists and artists were born, and began to develop work that was polar opposite. The sense of beauty itself became separated from science and was confined within the field of art. This dichotomy existed through mankind's efforts in advancing civilisation to its present state. This paper briefly examines the relationship between art and science through the ages and discusses their relatively recent re-convergence. Based on this hypothesis, this paper studies the current state of the convergence between arts and sciences and examines the current relationship between the two by considering real world applications and products. The study of such products and their successes and impact they had in the marketplace due to their designs and aesthetics rather than their advanced technology that had partially failed them appears to support this argument. This text further argues that a re-convergence between art and science is currently occurring and highlights the need for accelerating this process. It is suggested that re-convergence is a result of new technologies which are adopted by practitioners that include effective visualisation and communication of ideas and concepts. Such elements are widely found today in multimedia and Virtual Environments (VEs) where such tools offer increased power and new abilities to both scientists and designers as both venture in each other's domains. This paper highlights the need for the employment of emerging computer based real-time interactive technologies that are expected to enhance the design process through real-time prototyping and visualisation, better decision-making, higher quality communication and collaboration, lessor error and reduced design cycles. Effective employment and adoption of innovative design methods that ensure products are delivered on time, and within budget, are of the highest quality and meet customer expectations are becoming of ever increasing importance. Such tools and concepts are outlined and their roles in the industries they currently serve are identified. Case studies from differing fields are also studied. It is also suggested that Virtual Reality interfaces should be used and given access to Computer Aided Design (CAD) model information and data so that users may interrogate virtual models for additional information and functionality. Adoption and appliance of such integrated technologies over the Internet and their relevance to electronic commerce is also discussed. Finally, emerging software and hardware technologies are outlined and case studies from the architecture, electronic games, and retail industries among others are discussed, the benefits are subsequently put forward to support the argument. The requirements for adopting such technologies in financial, skills required and process management terms are also considered and outlined.

summary Based on a comparison between the perception of digital and real construction, the development of virtual systems and the review of additional sources, this paper states some differences between the design of virtual environments and architectural spaces. Virtual-reality technologies provide advanced capabilities to simulate real situations, and also to create digital worlds not referred to physical places, such as imaginary landscapes or environments devoted to electronic activities, like entertainment, learning or commerce. Some on-line services already use 3D-stages, resembling building halls and domestic objects, and several authors have mentioned virtual modeling as a job opportunity to architects. But it will argue in this paper that the design of those environments should consider their own digital characteristics. Besides, the use of virtual installations on networks impells a convergence with global media, like Internet or TV. Virtual environments can be a 3Devolution of communicational technologies, which have an increasing participation in culture, reaching a closer relationship to contemporary architecture.

title Designs Conducive to the Use of Efficient Strategies
source Proceedings of DIS'00, (2000), 338-345
summary Studies on the widespread inefficient use of complex computer applications have suggested that users need to learn efficient strategies in addition to learning how to use tools. This paper argues that our growing understanding of strategic knowledge can be used to guide designers develop systems which are conducive to the use of efficient strategies. The paper first describes ten general strategies which appear to be useful across three computer application domains. Next, the paper discusses the functionalities required to execute the ten strategies, and what makes them conducive to strategy use. An analysis of six major computer applications in three domains reveals that these functionalities are not consistently offered, and how their absence directly affects the performance of complex tasks. The analysis leads to questions related to the generality of the results, the problem of featurism, and how strategy-conducive systems could facilitate the transfer of knowledge across applications. The paper concludes by briefly describing how we intend to use the strategy framework to develop analysis methods for designers and trainers.

summary The project IDEA+ aims to develop an “Integrated Design Environment for Architecture”. Its goal is providing a tool for the designer-architect that can be of assistance in the early-design phases. It should provide the possibility to perform tests (like heat or cost calculations) and simple simulations in the different (early) design phases, without the need for a fully detailed design or remodeling in a different application. The test for daylighting is already in development (Geebelen, to be published). The conceptual foundation for this design environment has been laid out in a scheme in which different design phases and scales are defined, together with appropriate tests at the different levels (Neuckermans, 1992). It is a translation of the “designerly” way of thinking of the architect (Cross, 1982). This conceptual model has been translated into a “Core Object Model” (Hendricx, 2000), which defines a structured object model to describe the necessary building model. These developments form the theoretical basis for the implementation of IDEA+ (both the data structure & prototype software), which is currently in progress. The research project addresses some issues, which are at the forefront of the architect’s interest while designing with CAAD. These are treated from the point of view of a practicing architect.

title A Generative Approach to Variations in Production Processes
source International Conference on Generative Art
summary Many work procedures in generating various types of products (such as execution of recipes for food, work operation for leather, procedures for conservation of vegetables, factory workmanship processes, etc) are characterised by precise procedural steps. Each step can be defined, at the proper detail level, in terms of kind of operations, input conditions, output results; then, a complete procedure can be exploited as a set of partially ordered steps of such a kind of functions. The formalisation of such a steps allows to evaluate procedures devoted to the same goal, introducing metrics for comparing them in terms of originality or imitation. Furtherly, a contextual analysis of different procedures devoted to similar goals allows to verify possible variations in the procedures, introducing innovation and changes on the basis of the available examples. The changes can be automated through proper algorithms, just using techniques of learning by examples, in the respect of verifiable constraints. The results can be verified, and used again as a new enriched experienced basis to improve the innovation procedures. The paper will describe the approach for the analysis and the description, will propose an experienced metric, and will show examples of generation of new innovative methods based on the automated analysis of successful examples. All the practical examples will be expressed in cooking recipes, described, compared in terms of plagiarism with properly defined metrics, improved with automatic generation based on experience and examples, properly checked and validated.
