title Envisioning Cyberspace: Designing 3D Electronic Spaces
source McGraw-Hill, NY
summary Free of the constraints of physical form and limited only by imagination, new environments spring to life daily in a fantastic realm called cyberspace. The creators of this new virtual world may be programmers, designers, architects, even children. In this invigorating exploration of the juncture between cyberspace and the physical world, architect Peter Anders brings together leading-edge cyberspace art and architecture ... inspiring new techniques and technologies ... unexpected unions of reality and virtuality ... and visions of challenges and opportunities as yet unexplored. More than an invitation to tour fantastic realms and examine powerful tools, this book is a hard-eyed look at cyberspace's impact on physical, cultural, and social reality, and the human-centered principles of its design. This is a book that will set designers and architects thinkingNand a work of importance to anyone fascinated with the fast-closing space between the real and the virtual.

summary This white-paper builds upon previous research to present hybrids of electronic and physical spaces as extensions of current design practice. It poses an hypothetical project - a hybrid of physical and cyberspaces - to be developed through an extrapolation of current architectural practice by fully exploiting new information technologies. The hybrid's attributes not only affect the scope of development but the very activities of the design team and client during - and after - deployment. The entire life cycle of the project is affected by its dual material and media presence. The paper concludes by discussing the effect the hybrid - here called a "cybrid" - on the occupant, and its local and global communities. It reviews the economics, administration, marketing, operation, flexibility, and extension of the project to assess its effects on these scales. The conclusions are provisional owing to the youth of the technologies. However, in laying out these issues, the author hopes to begin a discussion on effects computation will have on our built environment.

summary The senses of “Touch” bring people the feeling of reality, and human beings can always naturally sense the tactile impression. Hence we touch things and our sense tells us that our hands are touching something (Hinckley et al. 1999). Comparing to the tools used by designers between traditional and new digital media in the design process, the most difference is in the sense of touch. This paper focuses on the sense of touch to point out the haptic experience which have ignored by the past in design process. Four phenomena will be discussed in details and some useful suggestions given for future study.

title Cyberspace: New Forms of Social Interaction
source III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 253-258
summary The cyberspace becomes into news forms of communication that transform and expand interaction among men. The objective of our reflection is to understand how space-time relations are changed by the new technologies of communication and information. The starting point of this analysis is the historic dimension of production, interaction and appropriation of space-time processes, proceeding in the se of solving their contemporary forms defined by the growing technology of daily life. It is possible to notice how communication expands the interaction among companies, institutions and society because processes and procedures are publicized, reducing the disorder and uncertain. It is a way of making social complexities more accessible, more clear, being easier read by individuals so they are able to lead with the complex of opportunities and responsibilities that compound the social system. The fundamental constitution of cybernetic spaces is on its capacity of make accessible the processes of communication and information which expand the interaction eliminating intermediaries. The condition of material localization dissolves itself to give place tommunicative interaction. The essential of the question can be stated in the theory that explains that social practices are the result of a cognitive system. That statement send us to the heart of analysis over the importance of comprehending as a moment that precede the action. When societies can be read through a union of knowledge condensed all along their social and cultural development. The development of new technologies of communication and information make nations capable to produce, accumulate diffuse knowledge, conducting to an action of intelligent individuals who write the social development.

title Generative music composition in practice - a critical evaluation
source International Conference on Generative Art
summary This critical evaluation will discuss 4 computer based musical works which, for reasons I shall explain, I describe as non-linear or generative. The works have been constructed by me and publicly performed or exhibited during a two year period from October 1998 to October 2000. ‘In the beginning…’ interactive music installation, strangeAttraction, Morley Gallery, London. July 1999 ‘jnrtv’ live generative dance music May 1999 to Dec 2000 ‘jazz’ interactive music installation, another strangeAttraction Morley Gallery, London. July 2000-09-26 ‘the street’ architectural interactive music installation, University of Westminster Oct 2000 Introduction I have always loved the practice of composing, particularly when it means scoring a work to be played by a live ensemble. There is something about taking a fresh sheet of manuscript , ruling the bar lines, adding clefs, key and time signatures and beginning the gradual process of adding notes, one at a time to the score until it is complete that is gratifying and compensates for the enormous effort involved. The process of scoring however is actually one distinct act within the more general task of creating music. Recently, the notion of ‘composing’ has met challenges through an increased interest in non-linear compositional methods. It is actually the presence of Chaotic or uncontrolable elements which add real beauty to music and many if not all of the things we value. If we think of a sunset, waves lapping on the shore, plants, trees a human face and the sound of the human voice, these things are not perfect and more importantly perhaps, they are transient, constantly changing and evolving. Last year and again this year, I have organised an exhibition of interactive , non-linear music installations called 'strangeAttraction'. The title refers to what Edward Lorenz called a ‘strange attractor’ the phenomenon that despite vast degrees of Chaos and uncertainty within a system, there is a degree of predictability, the tendency for chaotic behaviour to ‘attract’ towards a probable set of outcomes. Composition that deals with 'attractors' or probable outcomes rather than specific details which are set in stone is an increasingly intriguing notion.

source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title Global relevance of total building performance
source Automation in Construction 8 (4) (1999) pp. 377-393
summary Global population and environmental trends demand a radical departure from current building and developmental processes. Applying total building performance thinking can reduce energy consumption, pollution and waste in existing and new construction by a factor of 4 and simultaneously can improve quality of life within buildings––measured through occupant satisfaction, health and productivity. The further development of advanced energy and water systems, and the application of appropriate technology and systems integration concepts will help to enable the elimination of `waste-streams', avoiding obsolescence, as well as managing industrial and agricultural nutrient streams. Instead of treating buildings and their contents as `pre-garbage', worse `pre toxic-waste', all material flows can be considered within life cycles for `cradle to cradle' use. These concepts can make major contributions towards the creation of more sustainable lifestyles with even greater quality in the industrialized countries and the development and implementation of sustainable urban and building infrastructures in rapidly emerging economies. Rather than the continued export of non-sustainable building solutions, this paper argues for the development and demonstration of such practices in the industrialized countries that would create a progressive 'pull' to enable the appropriate implementation of new practices.

summary This research intends to test the architectural application of Jean Piaget’s clinical observations, described in the book: The Child’s Conception of Space (Piaget, 1956), according to which topology is an ordering discipline, active in the human psyche. Earlier attempts, based on the principles of graph-theory, were able to cover only a narrow aspect of spatial relations, i.e. connectivity, and were mostly a-perceptional, visually mute. The “Spaceprint” method, explained and illustrated in co-author’s book: Thought Palaces (Magyar, 1999), through dimensional reduction, investigates volumetric, 3D characteristics and relationships with planar 2D configurations. These configurations, however, represent dual values: they are simultaneously the formal descriptors of both finite matter and (fragments of) infinite space. The so- called “Particular Spaceprint”, as a tool of design development in building, object, or urban scales, with the help of digital technology, could express - again simultaneously - qualities of an idea-gram and the visual, even tactile aspects of material reality. With topological surface-transformations, the “General Spaceprints”, these abstract yet visually active spatial formulas can be obtained.

title MAKING LIGHT TANGIBLE: SIMULATION OF LIGHT DESIGN WITHIN ARCHITECTURAL EDUCATION
source Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 1-6
summary In times where computer-assisted representations dominate the “market” of visual simulation, the major strongholds of simulation in true size in conveying (artificial) light configurations have been observed. Though light cannot be “touched” due to its material absence the human eye reacts extremely sensitively to differing constellations. In matters of seconds differences are perceived and classified. Opening up a rift between the various simulation techniques, however, would not prove wise. The normal procedure still consists of trial positioning of lighting objects on site (i.e.: 1:1 simulation at building site). Regarding the effort this causes attempts as to gaining similar results by means of (partial) computer representations are worth considering. The degree of abstraction, however, might be too significant to make for conclusive decisions. In other words: Can the gap between imagination and translation thereof into reality be bridged? This contribution deals with the experimental implementation of artificial light in the full-scale lab and its possibilities regarding the 1:1 simulation at the Vienna University of Technology, with special attention to the didactic aspects related thereto.

title ArTbitrariness in Music
source International Conference on Generative Art
summary Evolution is now considered not only powerful enough to bring about the biological entities as complex as humans and conciousness, but also useful in simulation to create algorithms and structures of higher levels of complexity than could easily be built by design. In the context of artistic domains, the process of human-machine interaction is analyzed as a good framework to explore creativity and to produce results that could not be obtained without this interaction. When evolutionary computation and other computational intelligence methodologies are involved, every attempt to improve aesthetic judgement we denote as ArTbitrariness, and is interpreted as an interactive iterative optimization process. ArTbitrariness is also suggested as an effective way to produce art through an efficient manipulation of information and a proper use of computational creativity to increase the complexity of the results without neglecting the aesthetic aspects [Moroni et al., 2000]. Our emphasis will be in an approach to interactive music composition. The problem of computer generation of musical material has received extensive attention and a subclass of the field of algorithmic composition includes those applications which use the computer as something in between an instrument, in which a user "plays" through the application's interface, and a compositional aid, which a user experiments with in order to generate stimulating and varying musical material. This approach was adopted in Vox Populi, a hybrid made up of an instrument and a compositional environment. Differently from other systems found in genetic algorithms or evolutionary computation, in which people have to listen to and judge the musical items, Vox Populi uses the computer and the mouse as real-time music controllers, acting as a new interactive computer-based musical instrument. The interface is designed to be flexible for the user to modify the music being generated. It explores evolutionary computation in the context of algorithmic composition and provides a graphical interface that allows to modify the tonal center and the voice range, changing the evolution of the music by using the mouse[Moroni et al., 1999]. A piece of music consists of several sets of musical material manipulated and exposed to the listener, for example pitches, harmonies, rhythms, timbres, etc. They are composed of a finite number of elements and basically, the aim of a composer is to organize those elements in an esthetic way. Modeling a piece as a dynamic system implies a view in which the composer draws trajectories or orbits using the elements of each set [Manzolli, 1991]. Nonlinear iterative mappings are associated with interface controls. In the next page two examples of nonlinear iterative mappings with their resulting musical pieces are shown.The mappings may give rise to attractors, defined as geometric figures that represent the set of stationary states of a non-linear dynamic system, or simply trajectories to which the system is attracted. The relevance of this approach goes beyond music applications per se. Computer music systems that are built on the basis of a solid theory can be coherently embedded into multimedia environments. The richness and specialty of the music domain are likely to initiate new thinking and ideas, which will have an impact on areas such as knowledge representation and planning, and on the design of visual formalisms and human-computer interfaces in general. Above and bellow, Vox Populi interface is depicted, showing two nonlinear iterative mappings with their resulting musical pieces. References [Manzolli, 1991] J. Manzolli.

source Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 70-80
summary Digital media are transforming the practice and teaching of design. Information technologies offer not only better production and rendering tools but also the ability to model, manipulate, and to understand designing in new ways. This paper outlines a thirteen-step methodology used in a seminar that teaches design students how to see, think, and form space using both digital and physical media.

The paper describes a systematic approach that follows the tradition of the Bauhaus principles of craftsmanship and visual perception. Precedents are drawn from the use of light, color and texture in the visual arts such as the glass collage assemblages of Albers and Moholy-Nagy’s camera-less photogram. References are also drawn from Kandinsky’s diagrammatic analysis of still life drawings and Kepes’s idea of the language of vision.

The focus of the paper is how digital media and physical material can be used interchangeably as instruments in a design environment. The investigation centers on developing teaching methods for seeing, thinking and making of spatial design. A sequence of experimental exercises stimulates students’ intuition and powers of analytical observation. This systematic approach helps students explore how space can be perceived and informed by using types of media that are significantly different in their nature. The methodology explores the concerns and techniques of making and exploring space through the use of light, shadow, motion, color and transparency.

title A perceptually based physical error metric for realistic image synthesis
source Alyn Rockwood, editor, SIGGRAPH 99 Conference Proceedings, Annual Conference Series, ACM SIGGRAPH, Addison Wesley
summary We introduce a new concept for accelerating realistic image synthesis algorithms. At the core of this procedure is a novel physical error metric that correctly predicts the perceptual threshold for detecting artifacts in scene features. Built into this metric is a computational model of the human visual system's loss of sensitivity at high background illumination levels, high spatial frequencies, and high contrast levels (visual masking). An important feature of our model is that it handles the luminance-dependent processing and spatiallydependent processing independently. This allows us to precompute the expensive spatially-dependent component, making our model extremely efficient. We illustrate the utility of our procedure with global illumination algorithms used for realistic image synthesis. The expense of global illumination computations is many orders of magnitude higher than the expense of direct illumination computations and can greatly benefit by applying our perceptually based technique. Results show our method preserves visual quality while achieving significant computational gains in areas of images with high frequency texture patterns, geometric details, and lighting variations.

The following is a detailed explanation of its functions:1) Outlined data display function of the building parts and materials. 2) 3-dimensional CAD models management. 3) LCC display function of building parts and materials. 4) Search function. This system supports the development of an efficient maintenance planning, and an efficient undertaking of the maintenance program. The concrete effects are as follow, (1) Cost-efficient building maintenance planning. (2) Building value increased by appropriate budget planning of maintenance. (3) Processing load and time are shortened. (4) Human mistakes are decreased.

title Modelling architectural design information by features : an approach to dynamic product modelling for application in architectural design
source Eindhoven University of Technology
summary Architectural design, like many other human activities, benefits more and more from the ongoing development of information and communication technologies. The traditional paper documents for the representation and communication of design are now replaced by digital media. CAD systems have replaced the drawing board and knowledge systems are used to integrate expert knowledge in the design process. Product modelling is one of the most promising approaches in the developments of the last two decades, aiming in the architectural context at the representation and communication of the information related to a building in all its aspects and during its complete life-cycle. However, after studying both the characteristics of the product modelling approach and the characteristics of architectural design, it is concluded in this research project that product modelling does not suffice for support of architectural design. Architectural design is characterised mainly as a problem solving process, involving illdefined problems that require a very dynamic way of dealing with information that concerns both the problem and emerging solutions. Furthermore, architectural design is in many ways an evolutionary process. In short term this is because of the incremental approach to problem solving in design projects; and in long term because of the stylistic development of designers and the continuous developments in the building and construction industry in general. The requirements that are posed by architectural design are concentrated in the keywords extensibility and flexibility of the design informationmodels. Extensibility means that designers can extend conceptual models with definitions that best suit the design concepts they wish to utilise. Flexibility means that information in design models can be structured in a way that accurately represents the design rationale. This includes the modelling of incidental characteristics and relationships of the entities in the model that are not necessarily predefined in a conceptual model. In general, product modelling does not adequately support this dynamic nature of design. Therefore, this research project has studied the concepts developed in the technology of Feature-based modelling, which originates from the area of mechanical engineering. These concepts include the usage of Features as the primitives for defining and reasoning about a product. Features have an autonomous function in the information model, which, as a result, constitutes a flexible network of relationships between Features that are established during the design process. The definition of Features can be specified by designers to formalise new design concepts. This allows the design tools to be adapted to the specific needs of the individual designer, enlarging the library of available resources for design. In addition to these key-concepts in Feature-based modelling as it is developed in the mechanical engineering context, the project has determined the following principles for a Feature-based approach in the architectural context. Features in mechanical engineering are used mainly to describe the lowest level of detail in a product's design, namely the characteristics of its parts. In architecture the design process does not normally follow a strictly hierarchical approach and therefore requires that the building be modelled as a whole. This implies that multiple levels of abstraction are modelled and that Features are used to describe information at the various abstraction levels. Furthermore, architectural design involves concepts that are non-physical as well as physical; Features are to be used for modelling both kinds. The term Feature is defined in this research project to reflect the above key-concepts for this modelling approach. A Feature is an autonomous, coherent collection of information, with semantic meaning to a designer and possibly emerging during design, that is defined to formalise a design concept at any level of abstraction, either physical or non-physical, as part of a building model. Feature models are built up entirely of Features and are structured in the form of a directed graph. The nodes in the graph are the Features, whereas the arcs are the relationships between the Features. Features can be of user-defined types and incidental relationships can be added that are not defined at the typological level. An inventory in this project of what kind of information is involved in the practice of modelling architectural design is based on the analysis of a selection of sources of architectural design information. This inventory is deepened by a case study and results in the proposition of a categorisation of architectural Feature types.

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 The study of a cyberuniversity derives from an analogy between real urban space and its virtual "substitution". It represents an attempt to balance some views, which seems to be contrary, exclusive, but they are just parts of the same wholeness. Especially the notion of a cyber society is lately considered such an exaggeration, that it is possible to forget the meaning of a real life experience and interactions, which are already threatened. One should contribute to the awarness that is used in such a comparison, it is "just" an analogy, not a real similarity. At the same time it is possible to point out some limitations of a cyberspace and indicate a more realistic view of the meaning of cyber communities. Awarness of the development processes could help to find a balance between reality and virtuality, using cyberfacilities not to destroy us (our identity) but to improve the quality of our (real) life.

title Automated Cost Analysis of Concept Design BIM Models
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 403-418.
summary AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

summary This paper proposes principles for the design of human-centered, anthropic cyberspaces. Starting with a brief examination of our cognitive use of space, it suggests that we address cyberspace as an extension of our mental space. The paper procedes with twelve concepts based on scientific and cultural observations with respect to individual cognition and social interaction. These concepts are general - not specific to any culture or technology in the accompanying arguments the author expands on these concepts illustrating them with examples taken from conventional and electronic media, space and cyberspace the author hopes with these conjectures to begin a discussion on the anthropology of space and its emulation.

title The Art of Emergence
source International Conference on Generative Art
summary Since several years, the term emergence is mentioned in the paradigm of chaos and complexity. Following this approach, complex system constituted by multitude of individual develop global behavioral properties on the base of local chaotic interactions (self-organization). These theories, developed in scientific and philosophical milieus are rapidly spreading as a "way of thinking" in the several fields of cognitive activities. According to this "way of thinking" it is possible revise some fundamental themes as the economic systems, the cultural systems, the scientific paths, the communication nets under a new approach where nothing is pre-determined, but the global evolution is determined by specific mechanisms of interaction and fundamental events (bifurcation). With a jump in scale of the life, also other basic concepts related to the individuals as intelligence, consciousness, psyche can be revised as self-organizing phenomena. Such a conceptual fertility has been the base for the revision of the artistic activities as flexible instruments for the investigation of imaginary worlds, metaphor of related real worlds. In this sense we claim to the artist a role of "researcher". Through the free exploration of new concepts, he can evoke qualities, configurations and hypothesis which have an esthetical and expressive value and in the most significant cases, they can induce nucleation of cultural and scientific bifurcation. Our vision of the art-science relation is of cooperative type instead of the conflict of the past decades. In this paper we describe some of the most significant realized artworks in order to make explicit the concepts and basic themes. One of the fundamental topics is the way to generate and think to the artwork. Our characterization is to see the artwork not as a static finished product, but as an instance or a dynamic sequence of instances of a creative process which continuously evolves. In this sense, the attention is focused on the "generative idea" which constitutes the envelop of the artworks generable by the process. In this approach the role of technology (computers, synthesizers) is fundamental to create the dimension of the generative environment. Another characterizing aspect of our artworks is derived by the previous approach and specifically related to the interactive installations. The classical relation between artist, artwork and observers is viewed as an unidirectional flux of messages from the artist to the observer through the artwork. In our approach artist, artwork and observer are autonomous entities provided with own personality which jointly intervene to determine the creative paths. The artist which generate the environment in not longer the "owner" of the artwork; simply he dialectically bring the generative environment (provided by a certain degree of autonomy) towards cultural and creative "void" spaces (not still discovered). The observers start from these platforms to generate other creative paths, sometimes absolutely unexpected , developing their new dialectical relations with the artwork itself. The results derived by these positions characterize the expressive elements of the artworks (images, sequences and sounds) as the outcomes of emergent behavior or dynamics both in the sense of esthetical shapes emergent from fertile generative environments, either in terms of emergent relations between artist, artwork and observer, either in terms of concepts which emerge by the metaphor of artificial worlds to produce imaginary hypothesis for the real worlds.
