title	Image and Shape: Two Distinct Approaches
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 410-415
summary	This paper is the result of two researches done at the district of Campeche, Florianópolis, by the Grupo PET/ARQ/UFSC/CAPES. Different aspects and conceptual approaches were used to study the spatial attributes of this district located in the Southern part of Santa Catarina Island. The readings and analysis of two researches were based on graphic pistures builded with the use of Corel 7.0 e AutoCadR14. The first research – "Urban Development in the Island of Santa Catarina: Public Space Study"- examined the urban structures of Campeche based on the Spatial Syntax Theory developed by Hillier and Hanson (1984) that relates form and social appropriation of public spaces. The second research – "Topoceptive Characterisation of Campeche: The Image of a Locality in Expansion in the Island of Santa Catarina" -, based on the methodology developed by Kohlsdorf (1996) and also on the visual analysis proposed by Lynch (1960), identified characteristics of this locality with the specific goal of selecting attributes that contributed to the ideas of the place its population held. The paper consists of an initial exercise of linking these two methods in order to test the complementarity of their analytical tools. Exemplifying the analytical procedures undertaken in the two approaches, the readings done - global (of the locality as a whole) and partial (from parts of the settlement) - are presented and compared.

title	Posicionamiento de Volúmenes Arquitectónicos Mediante Algoritmos Evolucionistas (Positioning of Architectural Volumes by Means of Evolutionist Algorithms)
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 176-181
summary	Configurational studies involve the groups of elements fulfilling restrictions defined by the designer in Architectural design. According to its necessities and intentions, the planner distributes the components of the group in a certain tridimensional way, establishing a composition. This operative procedure implies a classification system according to typologies that respond to a bigger system, and this in turn to another, until the whole is obtained. From the beginning the pattern should satisfy form restrictions, as well as dimensional and positional restrictions for each part that conforms the whole. Functional requirements are attended for each object satisfying relationships of connectivity and adjacency among them. In this work the parts are restricted by their relative position to a central element. Evolutionary Algorithms (EA) are used to solve this type of problem. Using evolutionary metaphors they originate concepts such as "genes", "chromosomes", "mutation", "crosses” and " population " (among other), which come closer to one of the solutions looked for by the designer, under combinatory stochastic methods. The most appropriate use of EA corresponds to problems of complexity NP-completeness (for example, problems of generation of cases of composition), allowing an efficient although not exhaustive analysis. Applying this technique to the generation of architectural volumes, some obtained results are exemplified.

title	Linear algebra and creative process
source	International Conference on Generative Art
summary	Mathematical methods providing metamorphosis of three-dimensional objects are considered. Linear algebra is the basic tool : precisely linear transformations depending on a parameter are the way to produce the basic surface, moreover logic rules of manipulation of its parametric equations allow the realization of the generative process. We think that mathematical methods introduced into a generative approach can increase the performances in the designing evolution. This paper illustrates an example realized by modifying mathematically a three-dimensional form, whose initial idea is recognisable at every step.

summary	By november 1996, the state telecomunication company called for a national booth design contest. The idea was to use the awarded design shortly as part of the renovation of the public phone service. Gruppo MDM won the design contest and was contracted to do the manufacture technical drawings and a prototype which was tested during 1997. By 1997, an international bid was held, including the awarded project. Gruppo MDM was contracted for the follow up of the manufacture process, including research of suppliers worldwide, materials arriving on time with the quality required, verifying local suppliers with deadlines and quality controlls according to the specifications.

title	An Interface for Sketching 3D Curves
source	ACM Symposium on Interactive 3D Graphics, pp. 17-22 (April 1999). ACM SIGGRAPH. Edited by Jessica Hodgins and James D. Foley
summary	The ability to specify nonplanar 3D curves is of fundamental importance in 3D modeling and animation systems. Effective techniques for specifying such curves using 2D input devices are desirable, but existing methods typically require the user to edit the curve from several viewpoints. We present a novel method for specifying 3D curves with 2D input from a single viewpoint. The user rst draws the curve as it appears from the current viewpoint, and then draws its shadow on the oor plane. The system correlates the curve with its shadow to compute the curve's 3D shape. This method is more natural than existing methods in that it leverages skills that many artists and designers have developed from work with pencil and paper.

source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 130-133
summary	This paper treats of the management of the position of objects on the plane. At first sight problems related with planning objects on the plane appear to be quite trivial. Nevertheless a system able to manage the permutation of objects the one with respect to the others becomes a complex one when all the possible variations are taken into account. The operations to be performed include topological variations in a combinatorial process. Although the results of such a system could be of general design application in this paper only architectural problems are examined as examples. In the first part an outline of the system is presented. In the second part a computer program directed to produce graphical results is described together with some case studies.

title	Design Thinking Proces and New Paradigms of Graphic Expression (Design Thinking Proces and New Paradigms of Graphic Expression)
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 68-73
summary	It is undeniable that infotechnology has brought significant changes into architectural representation. Whether these changes has altered design conception proccess or are only media matters, is a discussion concerned with the role of graphic expression in architects designs. Is it just a language, or a design thinking tool, fully engaged with the formal solution? Thus, the investigation of the role of represententional systems in the design thinking proccess and the analysis of their intrinsic relationship will approach traditional methods facing the widespread use of Computer Aided Design. There are polemics about the issue: on the one hand, seductive simulations and a plethora of rendering choices available, on the other hand, impersonal expression, to name a few arguments for and against CAD use. Computers have not replaced the straight reciprocity between the acts of conceiving and drawing, between mind and image, which results in manual sketches, quite effective in embodying a design idea. Yet, we have to admit that manipulating complex forms such as Gehry's Guggenheim Museum quickly would not be feasible before CAD advent. We have been faced with new paradigms challenging the graphic expression of architects and urban designers. Besides the consequences of this new reality to design thinking, a crucial point to be stressed at this discussion is the possibility of achieving a balance between the cherished mind-hand intimacy and the available technological resources.

title	CAAD Education under the Lens of Critical Communication Theories and Critical Pedagogy: Towards a Critical Computer Aided Architectural Design Education (CCAADE)

summary	Understanding the dominant ethos of our age is imperative but not easy. However it is quite evident that new technologies have altered our times. Every discipline is now forced to be critical in developing new concepts according to the realities of our times. Implementing a critical worldview and consciousness is now more essential than ever. Latest changes in information technology are creating pressure on change both in societal and cultural terms. With its direct relation to these technologies, computer aided architectural design education, is obviously an outstanding / prominent case within contemporary debate. This paper aims to name some critical points related to computer aided architectural design education (CAADE) from the perspective of critical communication studies and critical education theories. It tries to relate these three areas, by introducing their common concepts to each other. In this way, it hopes to open a path for a language of critique. A critique that supports and promotes experimentation, negotiation, creativity, social consciousness and active participation in architectural education in general, and CAADE in specific. It suggests that CAADE might become critical and produce meta-discourses [1 ] in two ways. Firstly, by being critical about the context it exists in, that is to say, its relationships to the existing institutional and social structures and secondly by being critical about the content it handles; in other words by questioning its ideological dimensions. This study considers that analysing the role of CAADE in this scheme can provide architectural education with the opportunity to make healthy projections for the future.

title	Interdisciplinary Collaboration in the Virtual Design Studio Design Studio
source	Proceedings of the 17th Annual EAAE Annual Conference, Plymouth UK
summary	Drastic changes in technology and economics currently impact common working structures. Moreover, a fundamental move of western societies from industrial and service oriented societies to information oriented societies can be observed. Like others, the AEC industry is also exposed to the challenge of these fundamental changes, not only regarding an ever growing stock of information on building components and materials, but also because of new methods of collaboration to be applied by all participants. As a result, integrating domain specific knowledge into the design process and conversely, conveying design intentions to domain experts, is meaningful in a constantly growing scale. Utilising advanced technology, a twofold approach in research and education, undertaken at the Institut für Industrielle Bauproduktion (ifib), University of Karlsruhe, is the basis of efforts to create and develop integrating methods of collaboration into the design and planning process. In addition, the integration of AEC practitioners (investors, users, designers, engineers) in the education process provides both drastic changes in the fields of design and construction education of students and a promising approach for life long learning. The focus of this paper is to present the current state of work and to report on experiences gathered during several Virtual Design Studios (VDS) in which multi-disciplinary participants from various Universities and backgrounds were involved. Platforms for the activities are World Wide Web based applications as well as animations, VR, CAD and video conferencing.

summary	This project investigates in the limits of the word like only means of structuring of the thought, before the appearance of new paradigms: the multimedias and the ciber-space that have transformed so much the language written as the architectural one causing unpublished situations: 1.) The transformation of a concrete container to other virtual. 2.) The transformation of the design object, of one static material to another that is a process. 3.) The transformation in the traditional ways of thinking (reversible as the formal logic of the mathematics) to new imaginarys epistemologicals. // These non alone events have caused changes in the forms of to know and to communicate the reality but rather the same one suffers a dilation process. We present for their exploration, a road synthesized in some hypotheses that were elaborated with reason of the International Competition of ACADIA 1998: 1.) The new communication systems (cibercomunication) they generate a new territory that should be colonized. This territory this conformed by objects related by infinite bonds (hipertext). 2.) The topographical form is not lineal and sequential, this it is multidirectional and multiradial. The phenomenon of the blow-up and the dilation are the mechanisms with those that the new objects are generated. 3.) These related fields generate interstitial empty spaces where it appears the desire. The interstice like existential space.

summary	After numerous studies and practical of use, field and laboratory measurements, carried out among the years 1994 and 1999, we arrived to the elaboration and presentation of a methodology for the bioclimatic design and energetically sustainable that already takes two books publications. With the support of more than 600 figures that facilitate the understanding of the concepts explained in the books and 26 computer software and databases, that are attached to the second book, the work is facilitated so that designers of buildings that have not been never in contact with a certain climate, or that they don’t have sufficiently assumed by means of the observation of the particularities of a certain climatic situation, to understand the form in that the climate influence their design, condition or determine the design solutions and averge strategies that will choose when carrying out an architecture work.

summary	In 1998, architecture schools in the three nation region of the upper Rhine came together to undertake a joint design studio. With the support of the Center for Entrepeneurship in Colmar, France, the schools worked on the reuse of the Kuenzer Mill situated near Herbolzheim, Germany. The students met jointly three times during the semester and then worked on the project at their home universities usng conventional methods. This project was essential to generating closer ties between the participating students, tutors and institutions and as such, the results were quite positive. So much so, that the organisers decided to repeat the exercise one year later. However, it became clear that although the students had met three times in large groups, the real success of a co-operative design studio would require mechanisms which allow far more intimate interaction among the participants, be they students, teachers or outside experts. The experiences from the Netzentwurf at the Institut für Industrielle Bauproduktion (ifib) showed the potential in a web based studio and the addition of ifib to the three nation group led to the development of the VuuA platform. The first project served to illuminate the the differences in teaching concepts among the partner institutions and their teaching staff as well as problems related to the integration of students from three countries with two languages and four different faculties: landscape architecture, interior design, architecture and urban planning. The project for the Fall of 1999 was the reuse of Fort Kléber in Wolfisheim by Strasbourg, France. The students again met on site to kick off the Semester but were also instructed to continue their cooperation and criticism using the VuuA platform.

title	Generative Polymodal Music Process
source	International Conference on Generative Art
summary	We present underlying ideas used to develop an Algorithmic Composition software named KYKLOS. It was designed to generate music based on generalised musical scales and modes. It is an interactive sonic device to be applied in composition as well in performance. The sonic output of the whole process can be described as generalised polymodal music since “synthetic scales” are generated by the algorithm. This environment can be used in a Computer Assisted Composition manner in order to generate MIDI files. On the other hand, it can equally be used as a performance environment in which a dynamic change of parameters enables a real time control of the sonic process. Recently, we advocated that several mathematical applications in Computer Music can be understood as Sound Functors [1]. In extension, we describe here a sound functor used to model scales and modes. As can be verified, part of early investigations on mathematical structures in music studied musical scales and modes using Combinatorics, Fibonacci Series and Golden Mean in order to understand compositional processes which use modal concepts. Using the Functor definition it is possible to enumerate n-scales as a sequence of integers. Each value in that sequence gives the distance (in half tones) between two consecutive tones. For example, the sequence 3:2:2:3 is interpreted as a pentatonic scale C-Eb-F-G-Bb, and as defined above it is a C mode. So, if we apply cyclical permutations, (n-1)-sequences of numbers should be interpreted as n-modes of tones. Our algorithmic implementation is described briefly. A n-mode is defined as an array with n-1 integers [a1, a2, ...an-1]. Each array generated at k-th step can be read as a number a1a2a3 ....an-1 in decimal representation, where ai is a integer between 1 and 9. We denote the number obtained at k-th step as (a1a2a3 ...an-1)(k) . The rules to implement the algorithm are the following:1) V0 = (1, 1, 1, 1 ......,1) (initial n-mode)2) ? ai ? 11 with i= 1, 2...n-1 (octave range constraint)3) Vk = (a1a2a3 ...an-1)(k) < (b1b2b3 ...bn-1)(k+1) = Vk+1 where aj ?bj , 1? j ? n-1.4) Vmax = (13 – n, 1, 1, ...,1)In this paper we start with a theoretical view and an introduction on the algorithmic mechanism used. Further, we present a concept of man ? machine interaction used to create the composition environment. We also describe the compositional graphic interface developed and general functions of the system. Finally there is a set of music examples generated by KYKLOS as MIDI files.

title	On multi body systems simulation in product design
source	KTH Stockholm
summary	The aim of this thesis is to provide a basis for efficient modelling and software use in simulation driven product development. The capabilities of modern commercial computer software for design are analysed experimentally and qualitatively. An integrated simulation model for design of mechanical systems, based on four different "simulation views" is proposed: An integrated CAE (Computer Aided Engineering) model using Solid Geometry (CAD), Finite Element Modelling (FEM), Multi Body Systems Modelling (MBS) and Dynamic System Simulation utilising Block System Modelling tools is presented. A theoretical design process model for simulation driven design based on the theory of product chromosome is introduced. This thesis comprises a summary and six papers. Paper A presents the general framework and a distributed model for simulation based on CAD, FEM, MBS and Block Systems modelling. Paper B outlines a framework to integrate all these models into MBS simulation for performance prediction and optimisation of mechanical systems, using a modular approach. This methodology has been applied to design of industrial robots of parallel robot type. During the development process, from concept design to detail design, models have been refined from kinematic to dynamic and to elastodynamic models, finally including joint backlash. A method for analysing the kinematic Jacobian by using MBS simulation is presented. Motor torque requirements are studied by varying major robot geometry parameters, in dimensionless form for generality. The robot TCP (Tool Center Point) path in time space, predicted from elastodynamic model simulations, has been transformed to the frequency space by Fourier analysis. By comparison of this result with linear (modal) eigen frequency analysis from the elastodynamic MBS model, internal model validation is obtained. Paper C presents a study of joint backlash. An impact model for joint clearance, utilised in paper B, has been developed and compared to a simplified spring-damper model. The impact model was found to predict contact loss over a wider range of rotational speed than the spring-damper model. Increased joint bearing stiffness was found to widen the speed region of chaotic behaviour, due to loss of contact, while increased damping will reduce the chaotic range. The impact model was found to have stable under- and overcritical speed ranges, around the loss of contact region. The undercritical limit depends on the gravitational load on the clearance joint. Papers D and E give examples of the distributed simulation model approach proposed in paper A. Paper D presents simulation and optimisation of linear servo drives for a 3-axis gantry robot, using block systems modelling. The specified kinematic behaviour is simulated with multi body modelling, while drive systems and control system are modelled using a block system model for each drive. The block system model has been used for optimisation of the transmission and motor selection. Paper E presents an approach for re-using CAD geometry for multi body modelling of a rock drilling rig boom. Paper F presents synthesis methods for mechanical systems. Joint and part number synthesis is performed using the Grübler and Euler equations. The synthesis is continued by applying the theory of generative grammar, from which the grammatical rules of planar mechanisms have been formulated. An example of topological synthesis of mechanisms utilising this grammar is presented. Finally, dimensional synthesis of the mechanism is carried out by utilising non-linear programming with addition of a penalty function to avoid singularities.

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.

summary	The dogmatic structure of architectural education has meant that the production and application of new educational theories, leading to educational models that use computer technology as their central medium of education, is still a relatively under-explored area. Partial models cannot deliver the expected bigger steps, but only bits and pieces. Curricula developments, at many schools of architecture, have been carried out within the closed circuit manner of architectural education, through expanding the traditional curricula and integrating computers into them. There is still no agreed curriculum in schools of architecture, which defines, at least conceptually, the use of computers within it. Do we really know what we are doing? In the words of Aart Bijl; 'If I want to know what I am doing, I need a separate description of my doing it, a theory' [Bijl, 1989]. The word 'sustainability' is defined as understanding the past and responding to the present with concern for the future. Applying this definition to architectural education, this paper aims to outline the necessity and the principles for the construction of a theory of a sustainable computer aided architectural education model, which could lead to an architectural education that is lasting.

title	The Computer Integrated Road Construction project
source	Automation in Construction 9 (5-6) (2000) pp. 447-461
summary	This paper is about the "Computer Integrated Road Construction" (CIRC) project, which is a Brite-EuRam III funded project, lasting 1997–1999, aiming at introducing a new generation of control and monitoring tools for road pavements construction. These new tools are designed to bring on the sites significant improvements by creating a digital link between design office and job site. The first part of the paper describes the background of the project, which gathers seven European partners from five different countries, and gives the objectives of the project, in general and for each of the two targeted products: one for the compactors (CIRCOM) and one for the asphalt pavers (CIRPAV). Then, the two prototypes are described, each of them being broken down into three main sub-systems: the ground sub-system (GSS), the on-board sub-system (OB) and the positioning sub-system (POS). The expected benefits for the different users are also presented and quantified. The central part of the paper is devoted to the main technical innovations that have been developed in the frame of the project: universal vector database for road equipment guidance, multi-machine functionalities of CIRCOM and the two positioning systems which are actually the technological keys of the systems. Finally, the state of progress of the developments of the two CIRC products and the first commercial success achieved in parallel are presented.

summary	This work presents the synthesis of a model of urban growth dedicated to accomplish simulations of urban spatial dynamics, based on integrated urban and environmental factors and promoting simultaneity among external and internal growth. The city and surrounding environment are captured and modeled in computational ambient, by application of the centrality / potential model (Krafta, 1994 and 1999), with support of graph theory, cellular automata, GIS and geocomputation. The model assumes the city as a field of opportunities for obtaining income, mediated by the space, which is composed of urban and environmental attributes, that work as attractors or as resistances for the urban growth. The space configuration and the distribution of those attributes generate tensions that differentiate qualitatively and quantitatively the space, through the centrality measure (built with the support of graphs techniques), coming to provoke growth in places with larger potential of development (built with the help of techniques of CA – cellular automata). Growths above environmental thresholds are considered problems, generated and overcome in the same process of production of the urban space. Iterations of that process offer a dynamic behaviour to the model, allowing to observe the growth process along the time. The model presents several possibilities: a) urban - natural environment integration; b) internal and external growth integration; c) variety in the scale; d) GIS integration and geocomputation; e) user interface; f) calibration; g) theoretical possibilities; and h) practical possibilities.
