summary The features of complexity in architectural design have now been clarified. Complexity, intrinsic in architectural work, has increased in recent years as in all other fields of human endeavour – social, economic and cultural. In the specific case of architectural design, the most significant factors in this regard consist of the large number of actors, the numerous disciplines involved, technological innovation, regulations and rules governing the design process and the various different design aims. In order to address this complex of problems, long-term research based on the Collaborative Design paradigm, CD, is now being carried out. In it, thanks to the reciprocal exchange of information, the complementary nature of the knowledge possessed by the various actors, and the contemporary nature of the design action by the various actors on the same components, positive effects are exerted on the design as a whole. The latter thus gains in coherence and in improved integration among the design solutions proposed by the various actors. In CD all the actors are involved from the outset of the design work and are helped by distributed Knowledge Bases (KBs) and Intelligent Assistants (IAs). In this case it may happen that information and knowledge automatically exchanged among KBs (through the IAs) are excessive and/or not addressed to the right actors. How can information redundancy be avoided, and how can the flow of information sent over the network be controlled? The present paper introduces and defines the concept of „Audience“, that is, the group of actors to which it is permitted to send information concerning non respected requirements and the „reduced Audience“ to which to send the knowledge needed to overcome the difficulties encountered.

title STUDY ON COMPUTER-AIDED DESIGN SUPPORT OF TRADITIONAL ARCHITECTURAL THEORIES
source Technische Universität München
summary The research presented in this thesis describes a computer-aided design support of traditional architectural theories. Traditional architectural theories in western architecture have been considered as a basis for answering the fundamental questions of architecture: proportion, symmetry, colour, harmony and so on. In particular, the aesthetic aspect of these theories has been one of many important architectural aspects, and which is concerned with the field of architecture in determining the beauty of architectural form. The most significant role of the traditional theories in architecture is to maintain unity, to avoid chaos and then to achieve harmony in a design, using some specific design principles. However, current technology-guided constructions tend to neglect often the importance of these theories due to the standardization of building elements, due to mechanically-prepared construction and the reducing completion costs, etc. Thus, this research proposes a design support system as a design assistant that gives an intelligent advice on architectural design, using analytical design- and ordering- principles of traditional theories for the optimization of the architectural design from the aesthetic perspective. To evaluate the aesthetic quality of an architectural design, this system is implemented in the AutoCAD environment, using the AutoLISP. It is applied so as to explain and develop aesthetic qualities of a design. Designs proposed by this system include optimum designs, which are based on the traditional architectural theories, and new ones which can be in future connected to information models. To do this, the definition of information about building elements is accomplished by using the neutral format EXPRESS and EXPRESS-G for such application systems. The results of the application system are presented, such as the easily generating and quickly conceptualising of an object model, the checking of the aesthetic value of the design during the various design phases, the helping to find direction during rational searching for a solution. The user can easily appreciate the usefulness of the proposed system as a set of tools for searching for rational architectural aesthetics and formal solutions at different design-stages. It is to be hoped that a new "traditional" fundamental of architecture, such as the proposed system, incorporating CAAD systems, will find its place among new technological methods in the AEC industry and so help to bridge the gap between the value of traditional architecture and CAAD systems.

summary The study describes some of the aspects tackled within a current Ph.D. research where architectural applications of constructive, structural and organization processes existing in biological systems are considered. The present information processing capacity of computers and the specific software development have allowed creating a bridge between two holistic nature disciplines: architecture and biology. The crossover between those disciplines entails a methodological paradigm change towards a new one based on the dynamical aspects of forms and compositions. Recent studies about artificial-natural intelligence (Hawkins, 2004) and developmental-evolutionary biology (Maturana, 2004) have added fundamental knowledge about the role of the analogy in the creative process and the relationship between forms and functions. The dimensions and restrictions of the Evo-Devo concepts are analyzed, developed and tested by software that combines parametric geometries, L-systems (Lindenmayer, 1990), shape-grammars (Stiny and Gips, 1971) and evolutionary algorithms (Holland, 1975) as a way of testing new architectural solutions within computable environments. It is pondered Lamarck´s (1744-1829) and Weismann (1834-1914) theoretical approaches to evolution where can be found significant opposing views. Lamarck´s theory assumes that an individual effort towards a specific evolutionary goal can cause change to descendents. On the other hand, Weismann defended that the germ cells are not affected by anything the body learns or any ability it acquires during its life, and cannot pass this information on to the next generation; this is called the Weismann barrier. Lamarck’s widely rejected theory has recently found a new place in artificial and natural intelligence researches as a valid explanation to some aspects of the human knowledge evolution phenomena, that is, the deliberate change of paradigms in the intentional research of solutions. As well as the analogy between genetics and architecture (Estévez and Shu, 2000) is useful in order to understand and program emergent complexity phenomena (Hopfield, 1982) for architectural solutions, also the consideration of architecture as a product of a human extended phenotype can help us to understand better its cultural dimension.

summary The paper presents the analyses of potential of networked media and computer tools for acting with the digital representations of local cultural values in order to describe and manage architectural cultural heritage. The classification of cultural heritage identifiers is presented, focussing on its applicability to organise digital storage and computer-assisted acting with cultural heritage.The objective of the paper is to inspire discussion about representing of “cultural identity” of digital data, in emphasize to possibilities of creating more digital tools and methods for management of cultural heritage. It is stated that handling complexity of architectural design should refer to heritage values. Generally, digital representations of architectural objects, similarly to real architecture, must have their cultural identities.

title MATHEMATICS FORMATION AND CREATIVE DESIGN
source Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 225-229.
summary One of the earliest human beings desires has been to inhabit a place that may assemble beauty and functionality. Architecture and Design have been the disciplines in charge to formalize it. Their study, as well as the way they are taught have been adapted to fit the needs; and the velocity of their transformation is even greater as well as the link between design, art and technology. Creativity, in it basic generic entity, is the capability to solve appropriately and originally phrased architectural problems which involves not only space, act, environment and semiotics but with everything related to make the project able to be constructed and inhabitable.

New technologies are based on complex algorithms which, by the use of simulators, achieve to produce complexity works that would have been unbelievable twenty year ago. These algorithms have a strong mathematical basis and allow to generate other working methods so as to create wonderful geometrical objects. The study of this New Geometry requires to explore and expand this field of knowledge in the Architecture studies. In order to analyze and use complex design systems to generate non linear experimental models, it is necessary the Mathematical contribution, not only at the University education stage but also at the professional life.

This New Mathematics adequately focused, is able and must be an essential ally to creative design which is born with an exercised imagination in the formation stage; therefore it must aid to establish a space where knowledge and ability for architectural work can be created, synthesized and experimented.

This work tries to encourage students and in relation to Geometry promotes the following aspects: (i) Inspection of new architectural spaces, (ii)Comprehension of the geometrical structure, (iii) Originality and common sense, (iv) Relation between Geometry and design of construction constitutive elements,(v) Insertion of man in the space, (vi) Conditioning of design to human body dimensions, (vii) Fractal geometries.

According to what has been expressed, this proposition acquires a fundamental significance to develop a spatial vision of geometrical shapes in students, in order to stimulate the understanding of the existing relation between abstract geometrical elements and their real applications in Architecture, Geometry and Design and Art. Besides, the purpose of this work has the aim to approach knowledge at the architectural design process and to the study of shapes and mathematical models that such designs sustain , and ultimately demonstrate the importance of an academic organization that involve teachers from different disciplines.

summary This paper integrates the investigations developed by the authors at Nomads.USP, where we proposes amplify the understanding circa the possible interfaces between the complex thought and the contemporary design process of concrete, hybrid, symbiotic and virtual spaces, through the reading and critical analyses of complex thought principles, over the trandisciplinary methodology. The goal of this project stage is to study alternatives to the conventional design process in architecture, searching possible inter-relations, and complementation, among diverse disciplines, by a transdisciplinary approach of the design process, permeated by the new Information and Communication Technologies [ICT]. Starting from these parameters we search contemporary design processes . developed and applied at the most diverse disciplines . that, by some manner, dialogue with this thought. Inside this context, two processes, defining as Software Engineering Paradigms, deserve special attention: Spiral model and Chaos model.

title The fifth elevation: Effects of digital graphic design and printing technologies on the urban fabric in developing countries
source SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary The paper reports on a study that identifies the effects of current advertising and printing technologies on urban spaces in developing countries. The complexities of these advertising applications form a complicated hierarchical web that requires an investigation of surface- volume-context relationships to minimize the tension between the graphical message and the urban fabric. Regressive application of technology-based graphic design and advertisement in the form of billboards and signage, form a new layer identified as the fifth elevation. The study endeavors for positive consequences of such elevations and differentiates between chaos and complexity. Consequently, the study categorizes various advertising schemes and recommends short-term guidelines to reduce chaotic amalgamation. Several design factors and new advertising schemes are proposed to sustain cultural and visual coherency of urban spaces. When applied, these recommendations could prove useful for many cities in the Middle East due to planning, cultural, economical, and religious, similarities.

There are several possibilities to the translation of the current Age of Information into built matter, and those which we believe to be the most important ones are the object of this study. The pop attitude of expendable architecture is the first manifestation of such media-oriented architecture, followed by the .deconstructivism. of sight and space. In a more dramatic transformation, we see the assimilation of the digital adding interactivity and mobility to the built environment, as matter dematerializes in ever-changing pixels, turning solid into speed and light.

summary This work is based on Oliver Grau.s analyses about some aspects of virtual reality. When making his considerations, Grau says virtual reality always has been part of artists. concern when creating their art and, as today, it is an atempt to keep the viewers envolved far from the real world, and deep inside another reality. Oliver Grau.s ponderations are pointed before. Then the comparisons among the installation named .The Place-Rhur., from Jeffrey Shaw, and the panoramas from the XIX and XX centuries are made. It is intended to point out that creations on virtual reality from today are extensions of those that came before. The difference resides on technology employed, cultural context from different moments in which they are created, and the level of envolvment they can offer.

title Digital media impact on the knowledge building and retrieving capability of architects
source SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary The transition of architecture from the two dimensional nature to the three dimensional nature, which results from the use of digital media, generates deep inconformity between the traditional methods of architectural creation and the novel nature of architectural objects. Therefore, there is a need to look at how digital media can impact the design capabilities of architects. This research aims at identifying the impact of digital media on the Knowledge Building and Retrieving capability, through defining this capability and classifying the basic approaches of digital media used in the design process. Depending on both primary data (a global questionnaire) and secondary data (synthesis of the previous research), the results of this study have substantiated the observation that there has been positive impact of various media settings (manual and digital) on the Knowledge Building and Retrieving capability of architects.

summary Hutt (1966) demonstrated that familiarity, clarity, simplicity, and congruity are four stimulus characteristics eliciting play. When the participant reaches this status of an activity, in which is at this point that the playfulness element enters into play, and play is an important ingredient of the creative process. Correspondently, the characteristics in digital design studios which are rapid and broad exploration, systematic design process, the use of suitable digital media, and problem solving system reveal the analogical qualities with play. Since creativity is crucial in design processes, it is worthwhile to study relationships between play and digital design studio to discover possible means to benefit and facilitate digital design learning.

summary This article summarizes the history of the standardization efforts in the architectural, engineering and construction industry and focuses on the three phases of the life cycle of a building, namely design, construction and use phases. Data and information needs of each phase tends to be quite different than one another, thus leading to difficulty in seamless exchange and integration between different constituents of the AEC industry. Downstream data users expect the architect to generate digital design information that is usable in the construction and use phases of a building.s life cycle. Recently American Institute of Architects have assembled a congress in Washington DC, bringing together representatives from the AEC/FM industry, government agencies, software industry and academic institutions. This paper is a summary of the presentation this author gave at this congress in April, 2004.

summary Keynote Paper - We are all involved in design.Besides being the (sub)conscious recipients of all sorts of design driven activities, we are professionally concerned with products of design and acts of designing, either as practitioners or as academics, in some cases as both… As someone who was trained as a designer, drifted into design teaching and presently attempts to combine composition research with design practice, I feel there is a need to bridge the cultural gap between design and design research. I intend to put forward the case for more designerly approaches in the study of design. In this context I would like to discuss perspectives for design driven studies by considering the following ensemble of aspects:- the matter of shifting attitudes to design in a scientific context; - the necessity of expanding the scope of instruments of design in relation to methods and insights. - the furthering of opportunities for networks aimed at bringing out and communicating findings concerning different aspects of design.It is on the topic of interaction, between the targeted creativity of designing on the one hand and the open minded search for relevant knowledge, insights and applications on the other, that I would like to dwell. Furthermore, I hope to provoke some thoughts – and hopefully responses – concerning the roles of computer based applications in such studies. What kinds of impulses have computer technologies offered, should they perhaps have offered and indeed might they still be able to offer in this field? I would like to by take a critical look back and try to turn things around, towards a possible view forward…

summary Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

title A Java Program Model for Design-Idea Exploration in Three Dimensions

summary Visual Perception of depictions is the basis of the act of imagining employed in visual design thinking of design process, and consequently in design-idea exploration. Digital-media use plays a significantly important role in these exploration processes. The underlying assumption of the research is that Visual Perception affects Design-Idea Exploration processes. The research investigates and sheds more light on the processes of Visual Perception, which architects use in mass exploration of design ideas. The research is a part of a series that presents a Java program based on creating 3d shapes, in order for architects to explore initial shapes related to design ideas. The initial version of the program, which is a part of another research, creates 3d shapes through controlling their dimensions and insertion point. Functions of painting, controlling the light position, and shading are added to the program that is presented in this research. The research discusses Design-Idea Exploration and Visual Perception and their correlation. The added features of the program that is used as a design medium are also presented and linked to the investigated areas.

summary Exploring design ideas, through two dimensional and three dimensional forms, is the basis of design exploration and visual design thinking during the design process. Imagining how drawings and models (be it manual or digital) will be presented in reality is the essence of visual design thinking. By the beginning of the 20th Century, architecture has become more three dimensional in design exploration and in representation. This transition to three dimensions makes the processes of visual design thinking more related to digital media. The nature of media, utilized by architects, affects design-exploration processes. The research investigates both the processes of visual design thinking and the interrelation between visual design thinking and digital media, in order to shed more light on how digital media should be introduced to students of architecture.

title An Evaluation of Neural Spatial Interaction Models Based on a Practical Application

summary One of the serious problems faced by the Brazilian municipalities is the scarcity of resources for building education infrastructure. This asks for an optimal allocation of the available resources that includes, among other things, a rational spatial arrangement of the supply points (i.e., schools) in order to increase the demand coverage (i.e., students). If it is possible to foresee the regions where the demand is going to be concentrated, it is then possible to plan the location of new facilities and to assess the impact on the future level of service of the entire system. Considering that one of the consequences of the location-allocation process is the distribution of trips from demand points to supply points throughout the city, therefore affecting the overall intraurban accessibility conditions to essential services such as education, there is a strong need of models that planners can rely on to predict the future trip distribution patterns. As a result, the objective of this work was to evaluate the performance of Artificial Neural Networks (ANN) when applied to spatial interaction models, the so-called Neural Spatial Interaction Models. This was done in a practical context, in contrast to the more theoretical works commonly found in literature. The practical application showed that the neural spatial interaction model had different performances when compared to the traditional gravity models. In one case the neural models outperformed the gravity models, while on the other case it was just the opposite. The explanation for this may be in the data or in the ANN model formulation, as discussed in the conclusions.

summary The Academic Upgrade Program (.Capacitación Docente.) is been developed in the contexto of a MECESUP project (government funding assignments for education) at the FAU of Universidad de Chile. This program is about upgrading knowledge and user capabilities in Information and Communication Technologies (IT) of our academic team, in order to improve our pedagogical model, and to include these IT into the learning-teaching process for Architecture, Design and Geography. Considering that new technologies are part of the contemporary professional development and they are already included in high school in Chile, they should be part of the university academic environment as well, as an important tool and a link between generations, careers, and stages of education. Estimulating a cultural transformation process in the academic team, promoting transversal network thinking and to generate a base of knowledge in digital culture are our main objectives. This is our contribution to a new academic model, which we need in deed.

summary An exploration on the analogy-based idea generation process in industrial design is reported. In particular we try to identify relationships between the sketching process and the analogy building in order to elicit requirements for a supporting software. We use concurrent think aloud protocols to obtain experimental data and an extension of a proved content oriented schema to analyze them. Statistical analysis on segments containing .analogical chains. found relations between analogical and design actions that allow us to support the hypothesis that the sketch seems to be more useful for helping the analytical aspects of the analogical making (i.e. to code a situation in terms of higher order relations) than the synthetic ones (i.e. to identify an analogy source). Results were interpreted as software requirements for a Computer Aided Design Application.

summary The paper introduces a Multi Agent Systems (MAS) approach to crowd modelling and simulation, based on the Situated Cellular Agents (SCA) model. This is a special class of Multilayered Multi Agent Situated System (MMASS), exploiting basic elements of Cellular Automata. In particular SCA model provides an explicit spatial representation and the definition of adjacency geometries, but also a concept of autonomous agent, provided with an internal architecture, an individual state and behaviour. The latter provides different means of space-mediated interaction among agents: synchronous, between adjacent agents, and asynchronous among at-a-distance entities. Heterogeneous entities may be modelled through the specification of different agent types, defining different behaviours and perceptive capabilities. After a brief description of the model, its application to simple crowd behaviours will be given, and an application providing the integration of a bidimensional simulator based on this model and a 3D modelling application (3D Studio) will also be described. The adoption of this kind of system allows the specification and simulation of an architectural design with reference to the behaviour of entities that will act in it. The system is also able to easily produce a realistic visualization of the simulation, in order to facilitate the evaluation of the design and the communication with involved decision-makers. In fact, while experts often require only abstract and analytical results deriving from a quantitative analysis of simulation results, other people involved in the decision-making process related to the design may be helped by qualitative aspects better represented by other forms of graphical visualization.
