title Data Representation Architecture: Visualization Design Methods, Theory and Technology Applied to Anesthesiology
source Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 91-102

summary The explosive growth of scientific visualization in the past 10 years demonstrate a consistent and tacit agreement among scientists that visualization offers a better representation system for displaying complex data than traditional charting methods. However, most visualization works have not been unable to exploit the full potential of visualization techniques. The reason may be that these attempts have been largely executed by scientists. While they have the technical skills for conducting research, they do not have the design background that would allow them to display data in easy to understand formats. This paper presents the architectural methodology, theory, technology and products that are being employed in an ongoing multidisciplinary research in anesthesiology. The project’s main goal is to develop a new data representation technology to visualize physiologic information in real time. Using physiologic data, 3-D objects are generated in digital space that represent physiologic changes within the body and show functional relationships that aid in the detection, diagnosis, and treatment of critical events. Preliminary testing results show statistically significant reduction in detection times. The research outcome, potential, and recently received NIH grant supporting the team’s scientific methods all point to the contributions that architecture may offer to the growing field of data visualization.

title Study of digital morphing tools during the design process - Application of freeware software and of tools in commercial products as well as their integration in AutoCAD
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary This research work examines methods of experimental designing with CAAD in a CAD laboratory with architecture students as the testing persons. Thereby the main focus is on the early phase of finding forms, in which different techniques with digital media are tried out in the didactic architectural design lessons. In these work have been traced the influences of the media employed on the design processes and combined the approaches of current CAAD research with aspects from classic design theory. For mathematical rules of proportion, atmospheric influence factors and analogy concepts in architecture, I have developed design methods which have been applied and verified in several series of seminars. (Kirschner, U.: 2000, Thesis, a CAAD supported architectural design teaching, Hamburg, school of arts). Previous experimental exercises showed that morphological sequences of modeling are effective sources for playful designing processes. In the current work these approaches are enhanced and supplemented by different morphological architectural concepts for creating shapes. For this purpose 2D based software like Morphit, Winmorph and other freeware were used. Whereas in the further development of this design technique we used 3D freeware morphing programs like zhu3D or Blender. The resulting morphological shapes were imported in CAD and refined. Ideally the morphing tool is integrated in the modeling environment of the standard software AutoCAD. A digital city model is the starting basis of the design process to guarantee the reference to the reality. The applied design didactic is predicated on the theories of Bernhard Hoesli. The act of designing viewed as „waiting for a good idea“ is, according to him, unteachable; students should, in contrast, learn to judge the „the force of an idea“. On the subject of morphology a form-generating method in the pre-design phase has been tested. Starting from urban-planning lines on an area map, two simple geometric initial images were produced which were merged by means of morphing software. Selected images from this film sequence were extruded with CAAD to produce solid models as sectional drawings. The high motivation of the students and the quality of the design results produced with these simple morphing techniques were the reason for the integration of the artistic and scientific software into the creative shape modeling process with the computer. The students learned in addition to the „bottom up “and „ top down” new design methods. In the presentation the properties and benefits of the morphing tools are presented in tables and are analyzed with regard to the architectural shape generating in an urban context. A catalogue of criteria with the following topics was developed: user friendliness, the ability of integrating the tools or as the case may be the import of data into a CAD environment, the artistic aspects in terms of the flexibility of shape generating as well as the evaluation of the aesthetic consideration of shapes.

title Measuring user satisfaction for design variations through virtual reality
source Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary This paper describes Virtual Reality as an environment to collect information about user satisfaction. Because Virtual Reality (VR) allows visualization with added interactivity, this form of representation has particular advantages when presenting new designs. The paper reports on the development of a VR system that supports architects to collect opinions about their design alternatives in terms of user preferences. An alternative to conjoint analysis, that uses statistical choice variations to estimate user preference functions, is developed. Artificial Intelligence (AI) Agent technology will be implemented to build a model for data collection, prediction, and learning processes.

summary This article investigates the potential applications of geographic information systems (GIS) in the analysis and simulation of dynamic processes in buildings and explores it within the context of life safety analysis of buildings. In doing so, the primary focus of the article is to look at how architectural components and spaces can be represented in a spatial database system and what types of methods must be used in the analysis of such a database. Until now GIS applications have primarily been seen as tools suitable for the analysis of urban design and planning problems, therefore an additional objective here is to bring GIS to the attention of architectural researchers as a potential tool for the representation and analysis of spatial data in architecture.

summary This paper presents the results of two design studio elective courses offered to students in their second and third semester of studies at the Design Studio Department, "Universidad Politécnica de Valencia, UPV." Classes are based on a methodology that directly relates the language of architectural form and space, to the language of the specific software being used. Our focus is not only to discover what may be represented, but most important what may not, and why. We aim to point out the differences between architecture as perceived and experienced by a human being, and its digital representation as a computer data structure. At the Digital Design Studio, students are faced with a sequence of two projects so as to learn the basics of architecture, while developing their skill to build a digital representation of it. The first exercise within this CAD sequence is reading and analyzing a built project: a study of precedent. With this exercise we aim at two goals: to decipher the keys or parameters of architectural design, from drawings and pictures, trying to recognize an "architectural language"; and to learn a particular syntax of digital modeling. The second exercise is a project of a single family house within a narrow rectangular site and with only one street elevation. With this project we focus on the strong impact of stairs on the organization of functions and circulation, the illumination and ventilation of spaces with double heights and patios, and study the power of the section to express clearly the organization of spaces.

title Toward a procedure of computer simulation in the restoration of historical architecture
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary In the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

LAB[au] elaborates a “hyperdesign” investigating the implications of new technologies of communication and computation in spatiotemporal and social processes and their forms of representation as architecture and urbanism. The transposition of the hypertext model to architectural and urban concepts question the mutation of the spatial and semantic construct of space. The definition of architecture as a code is based on “glocal” systems according to the processes of computation and communication.

title Towards generic representations of designs formalised as features
source Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary Feature-Based Modelling (FBM) is an information modelling technique that allows the formalisation of design concepts and using these formal definitions in design modelling. The dynamic nature of design and design information calls for a specialised approach to FBM that takes into account flexibility and extensibility of Feature Models of designs. Research work in Eindhoven has led to a FBM framework and implementation that can be used to support design.. Feature models of a design process has demonstrated the feasibility of using this information modelling technique. To develop the work on FBM in design, three tracks are initiated: Feature model descriptions of design processes, automated generic representation recognition in graphic representations, and Feature models of generic representations. The paper shows the status of the work in the first two tracks, and present the results of the research work.

summary The paper is focused around a critical discussion of the digital representation and the architectural design process. Digital technology is now widely accepted and computers are causing a profound impact in the way reality and artificial objects are described and represented. Computers are now transforming skills, design processes, production processes and organizations. However, the evidence suggests that there are no fundamental changes in the architectural design process. It is acknowledged that the design process in architecture goes through representations and entails two altering phases: one generating tentative possibilities and hypothesis, and another of testing and evaluation. Based on this discussion a new way of using digital technology in architectural conception and design is suggested.

title Java collaborative interface for architectural simulations A case study on wooden ceilings of Krakow
source International Conference On Conservation - Krakow 2000, 23-24 November 1998, Krakow, Poland
summary Concern for the architectural and urban preservation problems has been considerably increasing in the past decades, and with it the necessity to investigate the consequences and opportunities opened for the conservation discipline by the development of computer-based systems. Architectural interventions on historical edifices or in preserved urban fabric face conservationists and architects with specific problems related to the handling and exchange of a variety of historical documents and representations. The recent development of information technologies offers opportunities to favour a better access to such data, as well as means to represent architectural hypothesis or design. Developing applications for the Internet also introduces a greater capacity to exchange experiences or ideas and to invest on low-cost collaborative working platforms. In the field of the architectural heritage, our research addresses two problems: historical data and documentation of the edifice, methods of representation (knowledge modelling and visualisation) of the edifice. This research is connected with the ARKIW POLONIUM co-operation program that links the MAP-GAMSAU CNRS laboratory (Marseilles, France) and the Institute HAiKZ of Kraków's Faculty of Architecture. The ARKIW programme deals with questions related to the use of information technologies in the recording, protection and studying of the architectural heritage. Case studies are chosen in order to experience and validate a technical platform dedicated to the formalisation and exchange of knowledge related to the architectural heritage (architectural data management, representation and simulation tools, survey methods, ...). A special focus is put on the evolution of the urban fabric and on the simulation of reconstructional hypothesis. Our contribution will introduce current ARKIW internet applications and experiences: The ARPENTEUR architectural survey experiment on Wie¿a Ratuszowa (a photogrammetrical survey based on an architectural model). A Gothic and Renaissance reconstruction of the Ratusz Krakowski using a commercial modelisation and animation software (MAYA). The SOL on line documentation interface for Kraków's Rynek G_ówny. Internet analytical approach in the presentation of morphological informations about Kraków's Kramy Bogate Rynku Krakowskiego. Object-Orientation approach in the modelling of the architectural corpus. The VALIDEUR and HUBLOT Virtual Reality modellers for the simulation and representation of reconstructional hypothesis and corpus analysis.

summary Our paper presents recent developments of a co-operation program that links the MAP-GAMSAU CNRS laboratory (Marseilles, France), specialised in computer science and the HAiKZ Institute of Krakow's Faculty of Architecture, specialised in architectural heritage and conservation. Before undertaking any action to a listed building or interventions in its neighbourhood, it is vital to gain a clear understanding of the building in question. Numerous heterogeneous data detained by diverse institutions has to be handled. This process can be greatly eased by enhanced classification of the information. The development we present is a multidisciplinary platform independent information tool dedicated to education and research. SOL uses an http protocol centred computer architecture connecting a relational database, a VRML 2.0 representation module and a web search interface. It allows searches and updating of the database through a standard text based interface, a VRML 2.0 graphical module and a thematic interface. SOL is experienced on the urban fabric of the Main Square (Rynek Gówny) in Kraków. The choice of a web-centred development, both in the search and updating interface and in the representation module provides platform independence and distant access to the database, and enables successive contributions of students or researchers.

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.

summary Eternity, time without end, infinity, space without limits and virtuality, perception without constraints; provide the conceptual framework in which ACADIA 2000 is conceived. It is in human nature to fill what is empty and to empty what is full. Today, thanks to the power of computer processing we can also make small what is too big, make big what is too small, make fast what is too slow, make slow what is too fast, make real what does not exist, and make our reality omni-present at global scale. These are capabilities for which we have no precedents. What we make of them is our privilege and responsibility. Information about a building flows past our keyboards and on to other people. Although we, as architects, add to the information, it originated before us and will go beyond our touch in time, space and understanding. A building description acquires a life of its own that may surpass our own lives as it is stored, transferred, transformed, and reused by unknown intellects, both human and artificial, and in unknown processes. Our actions right now have unforeseen effects. Digital media blurs the boundaries of space, time and our perception of reality. ACADIA 2000 explores the theme of time, space and perception in relation to the information and knowledge that describes architecture. Our invitation to those who are finding ways to apply computer processing power in architecture received overwhelming response, generating paper submissions from five continents. A selected group of reviewers recommended the publication of 24 original full papers out of 42 submitted and 13 short papers out of 30 submitted. Forty-two projects were submitted to the Digital Media Exhibit and 12 were accepted for publication. The papers cover subjects in design knowledge, design process, design representation, design communication, and design education. Fundamental and applied research has been carefully articulated, resulting in developments that may have an important impact on the way we practice and teach architecture in the future.

summary Our collective concept of computing and its relevance to architecture has undergone dramatic shifts in emphasis. A review of popular texts from the past reveals the biases and emphases that were current. In the seventies, architectural computing was generally seen as an elective for data processing specialists. In the early eighties, personal computers and commercial CAD systems were widely adopted. Architectural computing diverged from the "batch" world into the "interactive" world. As personal computing matured, introductory architectural computing courses turned away from a foundation in programming toward instruction in CAD software. By the late eighties, Graphic User Interfaces and windowing operating systems had appeared, leading to a profusion of architecturally relevant applications that needed to be addressed in introductory computing. The introduction of desktop 3D modeling in the early nineties led to increased emphasis upon rendering and animation. The past few years have added new emphases, particularly in the area of network communications, the World Wide Web and Virtual Design Studios. On the horizon are topics of electronic commerce and knowledge markets. This paper reviews these past and current trends and presents an outline for an introductory computing course that is relevant to the year 2000.

title Swarm modelling. The use of Swarm Intelligence to generate architectural form
source International Conference on Generative Art
summary .neither the human purposes nor the architect's method are fully known in advance. Consequently, if this interpretation of the architectural problem situation is accepted, any problem-solving technique that relies on explicit problem definition, on distinct goal orientation, on data collection, or even on non-adaptive algorithms will distort the design process and the human purposes involved.' Stanford Anderson, "Problem-Solving and Problem-Worrying". The works concentrates in the use of the computer as a perceptive device, a sort of virtual hand or "sense", capable of prompting an environment. From a set of data that conforms the environment (in this case the geometrical representation of the form of the site) this perceptive device is capable of differentiating and generating distinct patterns in its behavior, patterns that an observer has to interpret as meaningful information. As Nicholas Negroponte explains referring to the project GROPE in his Architecture Machine: 'In contrast to describing criteria and asking the machine to generate physical form, this exercise focuses on generating criteria from physical form.' 'The onlooking human or architecture machine observes what is "interesting" by observing GROPE's behavior rather than by receiving the testimony that this or that is "interesting".' The swarm as a learning device. In this case the work implements a Swarm as a perceptive device. Swarms constitute a paradigm of parallel systems: a multitude of simple individuals aggregate in colonies or groups, giving rise to collaborative behaviors. The individual sensors can't learn, but the swarm as a system can evolve in to more stable states. These states generate distinct patterns, a result of the inner mechanics of the swarm and of the particularities of the environment. The dynamics of the system allows it to learn and adapt to the environment; information is stored in the speed of the sensors (the more collisions, the slower) that acts as a memory. The speed increases in the absence of collisions and so providing the system with the ability to forget, indispensable for differentiation of information and emergence of patterns. The swarm is both a perceptive and a spatial phenomenon. For being able to Interact with an environment an observer requires some sort of embodiment. In the case of the swarm, its algorithms for moving, collision detection, and swarm mechanics conform its perceptive body. The way this body interacts with its environment in the process of learning and differentiation of spatial patterns constitutes also a spatial phenomenon. The enactive space of the Swarm. Enaction, a concept developed by Maturana and Varela for the description of perception in biological terms, is the understanding of perception as the result of the structural coupling of an environment and an observer. Enaction does not address cognition in the currently conventional sense as an internal manipulation of extrinsic 'information' or 'signals', but as the relation between environment and observer and the blurring of their identities. Thus, the space generated by the swarm is an enactive space, a space without explicit description, and an invention of the swarm-environment structural coupling. If we consider a gestalt as 'Some property -such as roundness- common to a set of sense data and appreciated by organisms or artefacts' (Gordon Pask), the swarm is also able to differentiate space 'gestalts' or spaces of some characteristics, such as 'narrowness', or 'fluidness' etc. Implicit surfaces and the wrapping algorithm. One of the many ways of describing this space is through the use of implicit surfaces. An implicit surface may be imagined as an infinitesimally thin band of some measurable quantity such as color, density, temperature, pressure, etc. Thus, an implicit surface consists of those points in three-space that satisfy some particular requirement. This allows as to wrap the regions of space where a difference of quantity has been produced, enclosing the spaces in which some particular events in the history of the Swarm have occurred. The wrapping method allows complex topologies, such as manifoldness in one continuous surface. It is possible to transform the information generated by the swarm in to a landscape that is the result of the particular reading of the site by the swarm. Working in real time. Because of the complex nature of the machine, the only possible way to evaluate the resulting behavior is in real time. For this purpose specific applications had to be developed, using OpenGL for the Windows programming environment. The package consisted on translators from DXF format to a specific format used by these applications and viceversa, the Swarm "engine", a simulated parallel environment, and the Wrapping programs, to generate the implicit surfaces. Different versions of each had been produced, in different stages of development of the work.

title Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source Delft University of Technology
summary The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

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.

summary Description of class research from 1997-2 to 2000-1 in “Applied Computing in Architecture” conducted in the sixth semester of the Architecture Program at Faculdade de Belas Artes de São Paulo. The study is intended to analyze, evaluate and discover new paradigms in the introduction/application of class methodologies of teaching the use of computer in the design process. Our intention is to verify the students natural understanding of the principles of 3D digital modeling by introducing new tools for defining space and form, using the computer as a communication/representation system, and not only as a mimetized production tool. The challenge was to find a natural syntony between the digital projectual process and the learning process. At the end of each semester we evaluated the results and redirected the class proposals.
