summary	The research being conducted at the CABD LAB at the Department of Building and Environmental Control Technologies is geared to the production of an Expert System for architectural design, which is able to perform interactive design tasks and help to provide accurate and complete description of the buildings in question. The Expert System will control the design process, continually ensuring consistency between the definitions of the designer and a given set of constraints. Accordingly, the System will be able to determine the effects of of definition, performing the choices taken at different stages necessary calculations and checks. The System is based on a general representation of the building objects, from individual components to the whole building defined in terms of a number of hierarchical, topological and functional relational structures resulting from earlier research conducted into the automatic management of architectural design since 1975.

title	La Arquitectura como Extensión Fenotípica Humana - Un Acercamiento Basado en Análisis Computacionales [Architecture as human phenotypic extension – An approach based on computational explorations]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 56-60
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.

title	LOST IN SPACE? ARCHITECTURAL PSYCHOLOGY - PAST, PRESENT, FUTURE
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	A methodological review by Kaminski (1995) summed up five perspectives in environmental psychology - patterns of spatial distribution, everyday “jigsaw puzzles”, functional everyday action systems, sociocultural change and evolution of competence. Architectural psychology (named so at the Strathclyde conference 1969; Canter, 1973) as psychology of built environments is one leg of environmental psychology, the second one being psychology of environmental protection. Architectural psychology has come of age and passed its 25th birthday. Thus, a triangulation of its position, especially in Central Europe, seems interesting and necessary. A recent survey mainly on university projects in German-speaking countries (Kruse & Trimpin, 1995) found a marked decrease of studies in psychology of built environments. 1994, 25% of all projects were reported in this category, which in 1975 had made up 40% (Kruse, 1975). Guenther, in an unpublished survey of BDP (association of professional German psychologists) members, encountered only a handful active in architectural psychology - mostly part-time, not full-time. 1996, Austria has two full-time university specialists. The discrepancy between the general interest displayed by planners and a still low institutionalization is noticeable. How is the research situation? Using several standard research data banks, the author collected articles and book(chapter)s on architectural psychology in German- and English-language countries from 1990 to 1996. Studies on main architecture-psychology interface problems such as user needs, housing quality evaluations, participatory planning and spatial simulation / virtual reality did not outline an “old, settled” discipline, but rather the sketchy, random surface of a field “always starting anew”. E.g., discussions at the 1995 EAEA-Conference showed that several architectural simulation studies since 1973 caused no major impact on planner's opinions (Keul&Martens, 1996). “Re-inventions of the wheel” are caused by a lack of meetings (except this one!) and of interdisciplinary infrastructure in German-language countries (contrary to Sweden or the United States). Social pressures building up on architecture nowadays by inter-European competition, budget cuts and citizen activities for informed consent in most urban projects are a new challenge for planners to cooperate efficiently with social scientists. At Salzburg, the author currently manages the Corporate Design-process for the Chamber of Architecture, Division for Upper Austria and Salzburg. A “working group for architectural psychology” (Keul-Martens-Maderthaner) has been active since 1994.

title	Application of Genetic Algorithms to Establish Flooding Evacuation Path Model in Metropolitan Area
doi	https://doi.org/10.52842/conf.caadria.2004.557
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 557-570
summary	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. That could be divided into four parts. First, is to set the population of GA operation. Second, is to choose crossover and mutation. Third, is to calculate the fitness function of each generation and to select the better gene arrangement. Fourth, is to reproduce, after evolution, we can establish Flooding Evacuation Path that more reflect really human action and choice when flood takes place. However we can apply GA to calculate different evacuation path in different time series. Final, we compare and establish real model of evacuation path model to choosing flooding evacuation path.

title	A history and application of visual simulation in which perceptual behaviour movement is measured.
source	Architectural and Urban Simulation Techniques in Research and Education [3rd EAEA-Conference Proceedings]
summary	For our research on perception and judgment, we have developed a new visual simulation system based on the previous system. Here, we report on the development history of our system and on the current research employing it. In 1975, the first visual simulation system was introduced, witch comprised a fiberscope and small-scale models. By manipulating the fiberscope's handles, the subject was able to view the models at eye level. When the pen-size CCD TV camera came out, we immediately embraced it, incorporating it into a computer controlled visual simulation system in 1988. It comprises four elements: operation input, drive control, model shooting, and presentation. This system was easy to operate, and the subject gained an omnidirectional, eye-level image as though walking through the model. In 1995, we began developing a new visual system. We wanted to relate the scale model image directly to perceptual behavior, to make natural background images, and to record human feelings in a non-verbal method. Restructuring the above four elements to meet our equirements and adding two more (background shooting and emotion spectrum analysis), we inally completed the new simulation system in 1996. We are employing this system in streetscape research. Using the emotion spectrum system, we are able to record brain waves. Quantifying the visual effects through these waves, we are analyzing the relation between visual effects and physical elements. Thus, we are presented with a new aspect to study: the relationship between brain waves and changes in the physical environment. We will be studying the relation of brain waves in our sequential analysis of the streetscape.

title	Generative Process of Oskar Niemeyer‘s Style
source	2005 Aesthetics and Architectural Composition. Proceedings of the Dresden International Symposium of Architecture 2004 (to appear in "pro Literatur Verlag", D-82291 Mammendorf ISBN: 3-86611-022-7 / Editors: Ralf Weber/Matthias Albrecht Amann/ TU Dresden
summary	The aim of this study is to outline the structure of a possible grammar of Oscar Niemeyer’s architectural language, focusing on the so-called “free forms.” The idea is to assess the extent to which it is possible to shed some light on the discussion of architectural freedom as used by many authors when describing the work of the Brazilian architect. The investigation associates geometric relations present in Niemeyer’s buildings to the Shape Grammar model as proposed by Stiny & Gips (1975). The model made possible the depiction of consistencies in vocabulary, rules and operations deployed by Niemeyer. This eventually led to the description of an original architectural language present in Niemeyer’s buildings.

title	A framework for representing knowledge
source	P.H. Winston (ed.), The Psychology of Computer Vision, McGraw-Hill, New York, pp. 211-277
summary	Briefly describes frame systems as a formalism for representing knowledge and then concentrates on the issue of what the content of knowledge should be in specific domains. Argues that vision should be viewed symbolically with an emphasis on forming expectations and then using details to fill in slots in those expectations. Discusses the enormous problem of the volume of background common sense knowledge required to understand even very simple natural language texts and suggests that networks of frames are a reasonable approach to represent such knowledge. Discusses the concept of expectation further including ways to adapt to and understand expectation failures. Argues that numerical approaches to knowledge representation are inherently limited.

title	Illumination for Computer Generated Pictures
source	Communications of the ACM. June, 1975. vol. 18: pp. 311-317 : ill. (some col.). includes a short bibliography
summary	The quality of computer generated images of three-dimensional scenes depends on the shading technique used to paint the objects on the cathode-ray tube screen. The shading algorithm itself depends in part on the method for modeling the object, which also determines the hidden surface algorithm. The various methods of object modeling, shading, and hidden surface removal are thus strongly interconnected. Several shading techniques corresponding to different methods of object modeling and the related hidden surface algorithms are presented here. Human visual perception and the fundamental laws of optics are considered in the development of a shading rule that provides better quality and increased realism in generated images

title	On The Design of Surface Structures with Free Edges
source	1975. 18 p. : [3] p. of ill. includes bibliography: p. 14
summary	A method for finding the form of surface structures with free edges is presented. The necessary conditions are derived, based on a classification of surface structures to elliptic, hyperbolic and parabolic structures suggested by the author. The method is demonstrated on hyperbolic structures with and without straight line generators. A new form is developed: An hyperbolic paraboloid with generator lines and four free edges. Numerical examples are given, and the properties of each structure are investigated

title	The Effect of Stereovision on the Experience of VR Models of the External Surroundings and the Interior of a Building
doi	https://doi.org/10.52842/conf.ecaade.2005.391
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 391-398
summary	Virtual reality offers considerable promise with regard to facilitating the building process. A good example is the facilitation of communication between architects and building companies, sellers and buyers or between community planners and the general public. It is often thought that in order to utilise the potential of VR in, for example, the above-mentioned contexts, it is necessary to use fully fledged versions of VR, including stereovision and the possibility of controlling the VR show. However, if a model can also be presented on less advanced equipment and still interpreted in a way that is useful to the viewer it will be possible to distribute the model simply and effectively. This would make it easier to create a more democratic urban planning process compared with if specialised equipment needed to be used and special shows needed to be arranged. In this study we compared the experience of two VR models (a large indoor exhibition hall and an outdoor street in Gothenburg, Sweden) when presented with and without stereovision. When the experience was measured using the Semantic Environmental Scale (the SMB scale, developed by Küller, 1975, 1991), questions on the experience of presence and six other questions on the experience of the models, the results only revealed one indication that stereovision made a difference. This indication was the result for the SMB factor Enclosedness. Suggestions are presented for future research in this area.

title	Chaos, Databases and Fractal Dimension of Regional Architecture
doi	https://doi.org/10.52842/conf.ecaade.1998.267
source	Computerised Craftsmanship [eCAADe Conference Proceedings] Paris (France) 24-26 September 1998, pp. 267-270
summary	Modern research on chaos started in the 60's from an incredible finding that simple mathematical equations can model systems as complicated as waterfalls. In the 70's some scientists in the USA and in Europe started to find their way through the chaos. They were dealing with different spheres of science: mathematics, physics, biology, chemistry, physiology, ecology, economy. In the next 10 years? time the term 'chaos' has become generally known in science. Scientists gather in research groups according to their interests as to chaos and secondly according to their scientific specialities. (Gleick 1996) Objects that described chaos were irregular in shape, ripped. In 1975 Benoit Mandelbrot called them fractals. Fractal dimension that described fractal objects was also his invention. Fractal dimension is a way to measure quality: the degree of harshness, uneveness, irregularity of a given object. Carl Bovill (1996) showed how one can use fractal geometry in architecture and designing. This very fact made me try to use fractal geometry to deal with regional architecture. What or who is the degree of regionality of a given object to be for? A specially qualified person is able to state it nearly automatically. However, regionality is in some sense an unmeasurable feature. While dealing with data basis or checking particular projects, creation of procedures of automatic acquiring information concerning regionality is becoming a necessity.
