title	ARQUITECTURA, CINE Y LITERATURA: LA SEDUCCIÓN DE LA GEOMETRÍA

summary	¿Estamos presenciando un nuevo paradigma hacia otra forma de concebir la matemática?. El presente ensayo pretende indagar, a través del análisis y discusiones sobre diferentes obras literarias, cinematográficas y proyectos arquitectónicos, clásicos y contemporáneos, la relación entre la arquitectura y la literatura a partir de las estructuras matemáticas que los sustentan y cómo estas se han modificado o evolucionado a partir de los cambios tecnológicos de las últimas décadas. Relacionaremos la literatura y la arquitectura contemporánea pos revolución digital, con sus propiedades de nolinealidad y de fragmentación. Nuestra línea de investigación se centra en cuáles pueden ser las aportaciones esencialmente nuevas de la cultura digital a la producción de la arquitectura y la literatura, partiendo de su base estructural. La era informática trae con ella implicaciones que desestabilizan los conceptos tradicionales de espacio y tiempo. Nos preguntamos cuáles son los cambios en las estructuras textuales a partir de la era digital, cuáles son las nuevas estructuras geométricas, cómo influyen estas nuevas geometrías en la arquitectura, en el cine y en la literatura, en esta era de la información y qué rol ocupa la matemática en este cambio. El desarrollo de las ciencias contemporánea ha generado teorías que transforman nuestro conocimiento del universo. Caos, Teoría de la complejidad, Fractales son términos que caracterizan estos conceptos. En arquitectura estas teorías han tenido importancia en la producción de arquitectura "no-lineal" por medio de el uso de computadoras, especialmente en trabajos de arquitectos como Frank Gehry, Zevi Hecker, Greg Lynn, ARM y O.C.E.A.N UK, entre otros. En esta época informatizada la relación de la arquitectura con las demás ciencias (como la física y la matemática), con otros códigos como el lenguaje (por ejemplo en la narración) y con los límites del pensamiento filosófico, pueden hallarse hoy, tanto en el repertorio del deconstructivismo, en el repertorio “minimalista”, como en las abstracciones de los jóvenes nacidos con la computadora, que emulan cintas de Moebius, topologías “no euclideanas”, “estructuras líquidas” o ya en el campo de la literatura formas virtuales como en Calvino o dimensiones paralelas, bifurcadas, etc. como en Cortázar o Borges. Sin embargo, podemos preguntarnos si esta proliferación exuberante es el desarrollo de un organismo sólidamente construido, que adquiere cada día más cohesión y unidad en su propio crecimiento o si, por el contrario, no es más que el signo exterior de una tendencia a un fraccionamiento cada vez mayor, debido a la naturaleza misma de las matemáticas y si éstas no se estarán convirtiendo en una torre de Babel de disciplinas autónomas, aisladas unas de otras, tanto en sus principios como en sus métodos e incluso en su lenguaje. En una palabra, hoy, en esta tendencia, ¿estamos presenciando un nuevo paradigma hacia otra forma de concebir la matemática?.

title	Improved Understanding of Urban Sprawl Using Neural Networks
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 14020-2408-8, p. 33-49
summary	It is widely accepted that the spatial pattern of settlements is a crucial factor affecting quality of life and environmental sustainability, but few recent studies have attempted to examine the phenomenon of sprawl by modelling the process rather than adopting a descriptive approach. The issue was partly addressed by models of land use and transportation which were mainly developed in the UK and US in the 1970s and 1980s, but the major advances were made in the area of modelling transportation, while very little was achieved in the area of spatial and temporal land use. Models of land use and transportation are well-established tools, based on explicit, exogenouslyformulated rules within a theoretical framework. The new approaches of artificial intelligence, and in particular, systems involving parallel processing, (Neural Networks, Cellular Automata and Multi-Agent Systems) defined by the expression “Neurocomputing”, allow problems to be approached in the reverse, bottom-up, direction by discovering rules, relationships and scenarios from a database. In this article we examine the hypothesis that territorial micro-transformations occur according to a local logic, i.e. according to use, accessibility, the presence of services and conditions of centrality, periphericity or isolation of each territorial “cell” relative to its surroundings. The prediction capabilities of different architectures of supervised Neural networks are implemented to the south Metropolitan area of Milan at two different temporal thresholds and discussed. Starting from data on land use in 1980 and 1994 and by subdividing the area into square cells on an orthogonal grid, the model produces a spatial and functional map of urbanisation in 2008. An implementation of the SOM (Self Organizing Map) processing to the Data Base allows the typologies of transformation to be identified, i.e. the classes of area which are transformed in the same way and which give rise to territorial morphologies; this is an interesting by-product of the approach.

title	Completion of the Public Area of the Bratislava Main Station using Fine Art Components
source	Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 113-115
summary	The project deals with supplementation of fine art components to the newly designed square in front of the main railway station and their integration into the public space to provide a good system functioning in the contemporary ground-floor level. Several students of Faculty of Architecture, Slovak University of Technology in Bratislava, have elaborated this idea under the leadership of B. Kubinsky with the technical support of P. Kardos during the years 2001 and 2002. The supplementation had been planned in two parts: first each student has designed his own object of art and created the model of his piece. Then, in the second part, the quality and relevance of each object was verified by the spatial endoscope in the laboratory of P. Kardos.

title	Adapting Epidemiological Methodologies to the Prediction of Health Effects of Built Environment Interventions
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 283-290
summary	The influence of built environments on vitality and productivity of users is paramount. Since the introduction of Industrial, Flexible and Demountable Building, domotics, smart buildings, in general: mass-produced, intelligent and learning built environments, tailored built environments are within reach. This has resulted in the need for methodologies to predict short-term and long-term health effects of different built-environment constellations. Epidemiology has developed and validated methods to assess changes in prevalence of inflictions and other unhealthy conditions, as well as the number of healthy and vital years in a life span. After analysing the relationships among building (services) parts and its combinations, health determinants (exposures) and health outcomes, we could adapt the healthy years assessment (DALY) to changes in construction (insulation, air tightness) and building services engineering (ventilation, heating) for dwellings under Dutch conditions. The most important conclusion is that natural ventilation, mechanical ventilation and balanced ventilation not only differ in their average health effect, but even more so in the size of the ranges of these effects. Other systems, such as heat pumps or photo voltaic cells are expensive but will become economically applicable when healthcare costs are taken into account. These outcomes gave valuable clues for product innovation and opened the possibility to model health in relation to built environments. The method could also be applied to quality classification systems for dwellings.

title	Changing Roles for (Multi)Media Tools in Design - Assessing Developments and Applications of (Multi)Media Techniques in Design Education, Practice and Research
source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 530-539

summary	This contribution explores the continued evolvement of the instruments of design in relation to practice and education (and potentially: research) and attempts to characterize the effects brought about by recent media ‘shifts’. For this purpose a framework has been established to identify and ‘map’ relevant design media. The relationships between various ‘traditional’ media and computer based applications are scrutinized and characterized and the opportunities which they offer are compared. The underlying conceptual framework was recently put before a group of professionals in the in the course of an experimental workshop concerning the potentials of a virtual design media ‘museum’. In the following step an attempt is made to identify changing media roles, whereby the opportunities of the educational environment – as a ‘laboratory’ for emerging developments – is stressed. Some specific tendencies are identified, notably: the combined application of different sorts of design media; the surfacing of imaginative new working methods inspired by ‘classic’ media techniques and various new ways of escaping the serious limitations of traditional computer interfaces. These developments, making use of various types of computer platforms, may be expected to contribute to more structured – and imaginative – approaches to professional design as well as to architectural education and research.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title	VISTA VERSA – Critical Considerations on the Evolvement of Designerly Attitudes, Instruments and Networks in Design Driven Studies

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…

title	Communication and Value in Networked Design Coalitions

summary	The advent of the Internet has led us to believe that we live in an era of unprecedented globalization. In the field of building design, we now expect both that the local market for design services will be altered, and that many firms will take up the opportunity to pursue commissions beyond their local market. To some extent this is true, but it is instructive to recall that in the 19th century London based architectural firms and public works designers designed buildings throughout the Empire. Designing for projects beyond the local market is not new, what is new is our expectation that such a task is now fundamentally altered, made easier and more transparent, by the abundance of new communications technologies.It remains the case that working outside one’s local context is difficult and that when doing so, problems are likely to arise out of cultural differences. Distance too imposes its burdens, as the possibility to meet other members of the team face to face is reduced as the travel costs increase. This breaks down the possibilities of building informal networks among the individual designers working for the firms that are members of the design team. A re-instantiation of this informal network can only be done on the basis of a model of formal and informal communication in the design team. Many of the difficulties of collaborative work outside one’s local market are problems that have already been with us a long time. These problems arise out of the fact that buildings are designed by heterogeneous groups of people. The members of such groups must communicate with each other to share information and coordinate decisions and actions. Yet they are in different relations to the project at hand and have differing values arising out of their different backgrounds. This leads inevitably to conflict. Therefore, if we are to discuss communication and value then we must devote our attentions to conflict.

title	Using Bayesian Decision Networks for Knowledge Representation under Conditions of Uncertainty in Multi-Agent Land Use Simulation Models
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN 1-4020-24088, p. 129-144
summary	Land suitability analysis typically involves the assessment of the suitability of land units without knowing the future spatial distribution of land use. Traditional planning techniques have used “algebraic equations” to express land suitability as a weighted function of suitability scores across multiple criteria. However, the existing multi-criteria evaluation methods do not systematically account for uncertainty about the land use in adjacent and other cells. This paper proposes an alternative approach to land suitability analysis that does address the problem of uncertainty. In particular, Bayesian decision networks are suggested as a means of knowledge representation for agents in a multi-agent land use simulation system. Bayesian decision networks model the uncertainty in terms of probabilities specified in the network representing the expertise of specialists with respect to specific land uses. This paper discusses the approach and illustrates its use in the context of a retail agent.

title	Enhancing 3DSkyView Extension Performance
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-24088, p. 325-340
summary	This paper presents a second version of the 3DSkyView extension. The purpose of that extension was to implement a calculation algorithm for assessment and visualization of sky view factors (SVF) by means of tools available in a Geographical Information System (GIS). The sky view factor is a thermal and geometric parameter pointed out in the specialized literature as one of the main causes of urban heat islands. A 3D-GIS is a powerful tool for reaching the goal of this research because it allows the storage, treatment and analysis of tri-dimensional urban data, in addition to a high level of flexibility for incorporating calculation algorithms. The objective in the 3DSkyView extension is to optimize the determination of that factor, not only reducing its demanding calculation and graphical representation time, but also generating a simplified tool for replacing expensive photographic equipment usually applied on this matter. Enhancing functions of ArcView GIS 3.2, the first version of that extension showed a very good performance allowing the automatic delineation and determination of SVF. That performance was although limited to a single observer point. The simulation of SVF for several view points in urban canyons was only possible by applying the extension as many times as the number of observers considered. Therefore, this second version was now developed in order to allow simultaneous determination of SVF for many view points. In addition, the 3DSkyView new interface is more flexible, in a way that the user may choose the kind of output wanted (graphical and/or tabular). With this new feature it is then easier to create a continuous SVF map for an entire area.

summary	This study introduces a methodology for the evaluation, among a set of possible plans and/or policies, of a transport system which could reduce the effects of the network congestion on an urban area. Hence it is proposed a procedure which contains a new element compared with the current methodologies that is the final user’s evaluation of the examined system by turning to the application of the contingent valuation method, a technique like stated preferences. The approach we propose is based on the necessity for a determination of an optimal solution to the urban congestion to be established on the politic acceptability by the final user. Solutions which result virtually feasible for a public administration both on a technique and economic point of view often meet hostility by individuals. Consequently, it would be interesting for policy makers to adopt a process of valuation which could let to understand the user’s sensitivity and hostility towards specific configurations of the system, chosen as solution to decongestion (traffic calming, roadpricing, auto-free zones) and consequently to make less unpleasant the strategy to be carried out to control congestion (Harrington et al., 2001). In this way, a user does not judge the implementation of a set of projects made by a decision-maker as imposition and he is willing to pay in order to fulfil the chosen scenario. Finally we describe an application of the proposed methodology relating the definition of the integrated transport system in the metropolitan area of Bari, chief town of Apulia.

title	Applying Genetic Algorithms to Establish Disaster Decision Support System for Flooding Evacuation Path of Hsichih Area in Taiwan

summary	Because of the special geography features and subtropics weather in Taiwan, we need to provide correct information to help people making decision when they are in disaster. So the disaster decision support system must offer proper information of evacuation path to people. This research has shown the difficulties associated with the GIS and the flooding evacuation path search through the huge searching space generated during the network analysis process. This research also presents an approach to these problems by utilizing a search process whose concept is derived from natural genetics. Genetic algorithms (GAs) have been introduced in the optimization problem solving area by Holland (1975) and Goldberg (1989) and have shown their usefulness through numerous applications. We apply GA and GIS to choice flooding evacuation path in metropolitan area in this study. We take the region of Shiji city in Taiwan for case. Firstly, we establish the node relationship of GA calculation, the level of the weight is the standard of the date that is exported by Disaster Database. Secondly, we apply GA to calculate different evacuation path in different time series. Finally, we build the model of choosing flooding evacuation path.
