title Combined web crippling and bending moment failure of first-generation trapezoidal steel sheeting : experiments, finite element models, mechanical models
source Eindhoven University of Technology
summary Cold-formed trapezoidal sheeting of thin steel plate is a very popular product for building construction. It combines low weight and high strength and is economical in use. Current design rules, which predict sheeting failure for an interior support, do not provide sufficient insight into the sheeting behaviour, and can differ up to 40% in their predictions. To develop a new design rule, this thesis presents new experiments in which first-generation sheeting behaviour is studied for practical situations. The experiments show that after ultimate load, three different post-failure modes arise. Mechanical models have been developed for the three post-failure modes. These models can help to explain why a certain post-failure mode occurs. Finite element models were used to simulate the experiments. Studying stress distributions with finite element simulations, it can be seen that there are only two ultimate failure modes at ultimate load. One of these ultimate failure modes is not relevant for practice. A mechanical model has been developed for the other ultimate failure mode. This model performs as well as the current design rules, and it provides insight into the sheeting behaviour.

summary The following is a brief discussion of an alternative tool for teaching structural behavior to architecture and introduc-tory level engineering students. The advanced computer modeling and animation can be utilized to teach structural behavior in service condition in such a way that better meets the needs and capabilities of architecture students. It can provide a methodology and system, which develops an intuitive and conceptual understanding of structures before students can become overwhelmed with analytical and engineering mathematics. Coupled with appropriate technical instruction, these tools and methods facilitate a much stronger understanding of basic and advanced structures principles.

title Bridging GIS-based landscape analysis/modelling and 3D-simulation.Is this already 4D?
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary Several studies have used remote sensing to map patterns of e.g. deforestation or to analyse the rates of land use change. Thesestudies have proven useful for interpreting the causes of urbanization, deforestation etc. and the impact of such changes on theregion. Monitoring of change (e.g. deforestation or reforestation) is frequently perceived as one of the most important contributionsof remote sensing technology to the study of global ecological and environmental change (Roughgarden et al. 1991). Manyresearchers believe that the integration of remote sensing techniques within analysis of environmental change is essential if ecologistsare to meet the challenges of the future, specifically issues relating to global change; however, in practice, this integration has so farbeen limited (Griffiths & Mather 2000). Considerable difficulties are encountered in linking, on the one hand, the biologies oforganisms and the ecologies of populations to the fluxes of material and energy quantifiable at the level of ecosystems. In this paper,we concentrate on the methodological aspects of the delineation of landscape objects and touch the ecological application onlysuperficially but we elucidate the potential of the proposed methodology for several ecological applications briefly.

title The aesthetics of generative code
source International Conference on Generative Art
summary Aesthetics, in general usage, lays an emphasis on subjective sense perception associated with the broad field of art and human creativity. This paper suggests that it might be useful to revisit the troubled relationship between art and aesthetics for the purpose of discussing the value of generative code. It is now generally accepted that sense perception alone is simply not enough unless contextualised within the world of ideas. Similarly, the world of multimedia is all too easily conflated with a multi-sensory experience (of combining still and moving image, sound, interaction and so on). Thus the limits of traditional aesthetics is emphasised in the problem of defining which of the senses the highest of the arts adheres to -according to Kant and Hegel - the ‘arts of speech’. Poetry throws such crude classificatory distinctions into question as it is both read and heard; or written and spoken/performed. Hegel suggests a way out of this paradox by employing dialectical thinking; as we do not hear speech by simply listening to it. He suggests that we need to represent speech to ourselves in written form in order to grasp what it essentially is. Thus poetry can neither be reduced to audible signs (the time of the ear) nor visible signs (the space of the eye) but is composed of language itself. This suggests that written and spoken forms work together to form a language that we appreciate as poetry. But does code work in the same way? By analogy, generative code has poetic qualities too, as it does not operate in a single moment in time and space but as a series of consecutive ‘actions’ that are repeatable, the outcome of which might be imagined in different contexts. Code is a notation of an internal structure that the computer is executing, expressing ideas, logic, and decisions that operate as an extension of the author's intentions. The written form is merely a computer-readable notation of logic, and is a representation of this process. Yet the written code isn't what the computer really executes, since there are many levels of interpreting and compiling and linking taking place. Code is only really understandable with the context of its overall structure – this is what makes it a language (be it source code or machine code, or even raw bytes). It may be hard to understand someone else’s code but the computer is, after all, multi-lingual. In this sense, understanding someone else's code is very much like listening to poetry in a foreign language - the appreciation goes beyond a mere understanding of the syntax or form of the language used, and as such translation is infamously problematic. Code itself is clearly not poetry as such, but retains some of its rhythm and metrical form. Code is intricately crafted, and expressed in multitudinous and idiosyncratic ways. Like poetry, the aesthetic value of code lies in its execution, not simply its written form. To appreciate it fully we need to ‘see’ the code to fully grasp what it is we are experiencing and to build an understanding of the code’s actions. To separate the code and the resultant actions would simply limit the aesthetic experience, and ultimately the study of these forms - as a form of criticism (what might be better called ‘poetics’).

title Delivery Types And Communication Modalities In The Flat-Pack Furniture Design Critic
source T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary A computer-based design critiquing system analyzes a proposed solution and offers critiques (Robbins 1998). Critiques help designers identify problems as well as opportunities to improve their designs. Compared with human critics, today’s computer-based critiquing systems deliver feedback in quite restricted manner. Most systems provide only negative evaluations in text; whereas studio teachers critique by interpreting the student’s design, introducing new ideas, demonstrating and giving examples, and offering evaluations (Bailey 2004; Uluoglu 2000) using speech, writing, and drawing to communicate (Anthony 1991; Schön 1983). This article presents a computer-based critiquing system, Flat-pack Furniture Design Critic (FFDC). This system supports multiple delivery types and modalities, adapting the typical system architecture of constraint-based intelligent tutors (Mitrovic et al. 2007).

title A Photogrammetry and Perception Study of Chernikhov Fantasy No. 32 and 38
doi https://doi.org/10.52842/conf.caadria.2000.461
source CAADRIA 2000 [Proceedings of the Fifth Conference on Computer Aided Architectural Design Research in Asia / ISBN 981-04-2491-4] Singapore 18-19 May 2000, pp. 461-470
summary This research investigated the object composition in Chernikhov's 101 Architectural Fantasies through computer-aided visualization, for the purpose of interpreting the relationships between architectural components. In contrast to traditional simulation analysis, this research applied photogrammetry to investigate the orthogonal and parallel ambiguity of 3D objects in 2D drawings by calculating the position of matching geometries. This test took Fantasy no. 38 and 32 as examples to confirm their spatial relationship. 60 architectural students were asked to conduct 3 tests. The algorithmic approach (photogrammetry calculation) was referenced by a cognitive approach (the perception survey) as a comparison base. Photogrammetry test proved that the relation between objects was usually oriented by personal spatial experiences that did control the deduction process of an observer. Perception survey showed that orthogonal assumption existed in the interpretation process of an object's position. It turned out that a testee would still consider two linear objects intersected in orthogonal angle within a tolerance of 15 degree or parallel position between 4 and -16 degree. The finding showed that the interpretation of paper architecture drawings not only was given by the author, but tended to be re-interpreted by an observer. The interpretation process, just like modeling and rendering process, should be a two-way process that facilitates a study oriented either from 2D images or 3D models.

title Evolving the Shape of Things to Come - A Comparison of Interactive Evolution and Direct Manipulation for Creative Tasks
source International Conference on Generative Art
summary This paper is concerned with differences between direct manipulation and interactive evolutionary design as two fundamentally different interaction styles for creative tasks. Its main contribution to the field of generative design is the treatment of interactive evolutionary design as a general interaction style that can be used to support users in creative tasks. Direct manipulation interfaces, a term coined by Ben Shneiderman in the mid-seventies, are the kind of interface that is characteristic of most modern personal computer application user interfaces. Typically, direct manipulation interfaces incorporate a model of a context (such as a desktop environment) supposedly familiar to users. Rather than giving textual commands (i.e. "remove file.txt", "copy file1.txt file2.txt") to an imagined intermediary between the user and the computer, the user acts directly on the objects of interest to complete a task. Undoubtedly, direct manipulation has played an important role in making computers accessible to non-computer experts. Less certain are the reasons why direct manipulation interfaces are so successful. It has been suggested that this kind of interaction style caters for a sense of directness, control and engagement in the interaction with the computer. Also, the possibilities of incremental action with continuous feedback are believed to be an important factor of the attractiveness of direct manipulation. However, direct manipulation is also associated with a number of problems that make it a less than ideal interaction style in some situations. Recently, new interaction paradigms have emerged that address the shortcomings of direct manipulation in various ways. One example is so-called software agents that, quite the contrary to direct manipulation, act on behalf of the user and alleviate the user from some of the attention and cognitive load traditionally involved in the interaction with large quantities of information. However, this relief comes at the cost of lost user control and requires the user to put trust into a pseudo-autonomous piece of software. Another emerging style of human-computer interaction of special interest for creative tasks is that of interactive evolutionary design (sometimes referred to as aesthetic selection). Interactive evolutionary design is inspired by notions from biological evolution and may be described as a way of exploring a large – potentially infinite – space of possible design configurations based on the judgement of the user. Rather than, as is the case with direct manipulation, directly influencing the features of an object, the user influences the design by means of expressing her judgement of design examples. Variations of interactive evolutionary design have been employed to support design and creation of a variety of objects. Examples of such objects include artistic images, web advertising banners and facial expressions. In order to make an empirical investigation possible, two functional prototypes have been designed and implemented. Both prototypes are targeted at typeface design. The first prototype allows a user to directly manipulate a set of predefined attributes that govern the design of a typeface. The second prototype allows a user to iteratively influence the design of a typeface by means of expressing her judgement of typeface examples. Initially, these examples are randomly generated but will, during the course of interaction, converge upon design configurations that reflect the user’s expressed subjective judgement. In the evaluation of the prototypes, I am specifically interested in users’ sense of control, convergence and surprise. Is it possible to maintain a sense of control and convergence without sacrificing the possibilities of the unexpected in a design process? The empirical findings seem to suggest that direct manipulation caters for a high degree of control and convergence, but with a small amount of surprise and sense of novelty. The interactive evolutionary design prototype supported a lower degree of experienced control, but seems to provide both a sense of surprise and convergence. One plausible interpretation of this is that, on the one hand, direct manipulation is a good interaction style for realizing the user’s intentions. On the other hand, interactive evolutionary design has a potential to actually change the user’s intentions and pre-conceptions of that which is being designed and, in doing so, adds an important factor to the creative process. Based on the empirical findings, the paper discusses situations when interactive evolutionary design may be a serious contender with direct manipulation as the principal interaction style and also how a combination of both styles can be applied.

title The E-Talier: Inter-university Networked Design Studios
doi https://doi.org/10.52842/conf.ecaade.2000.045
source Promise and Reality: State of the Art versus State of Practice in Computing for the Design and Planning Process [18th eCAADe Conference Proceedings / ISBN 0-9523687-6-5] Weimar (Germany) 22-24 June 2000, pp. 45-50
summary The widespread infiltration of internet based variations of traditional areas of society (e-commerce, e-business, e-mail etc.) will not spare the halls of academia in its propagation. The term courseware is well nigh 20 years old and considerable research and development has been done in bringing network based distributed courses to university consortiums including those in architecture and civil engineering. Indeed, the European Commission has recently approved funding for a 3-year web-based virtual university of architecture and construction technology: the WINDS project led by the University of Ancona. Such attempts to create e-courses are largely an extension of typical courseware where the syllabus is quantified and divided into lessons for use by the students alone or in conjunction with their tutors and professors. This is quite adequate in conveying the base knowledge of the profession. However, the tenants of being an architect or engineer involve the deft use of that unwieldy named and deliciously imprecise tool called "design". Teaching design sooner or later involves the design studio: a pedagogically construed environment of simulation intended to train, not teach the skills of designing. This is fundamentally different from normal courseware. A network based design studio (Etalier) must be able to reflect the nature of learning design. Design studios typically involve specifically chosen design problems, researched supporting information to assist design decisions, focussed discussions, individual consultation and criticism, group criticism, public forums for presentation discussion and criticism as well as a myriad of informal undocumented communication among the students themselves. So too must an Etalier function. Essentially, it must allow collaboration through communication. Traditional barriers to collaboration include language, culture (both national and professional) and distance. Through the internet's capricious growth and the widespread use of English as a second language, the largest hurdle to attaining fruitful collaboration is probably cultural. In the case of an Etalier in a university setting, the cultural difficulties arise from administrative rules, the pedagogical culture of specific universities and issues such as scheduling and accreditation. Previous experiments with virtual design studios have demonstrated the criticality of such issues. The proposed system allows participating members to specify the degree and breadth with which they wish to partake. As opposed to specifying the conditions of membership, we propose to specify the conditions of partnership. Through the basic principal of reciprocity, issues such as accreditation and work load sharing can be mitigated. Further, the establishment of a studio market will allow students, tutors and professors from participating institutions to partake in studio projects of their choosing in accordance with their own constraints, be they related to schedule, expertise, legal or other matters. The paper describes these mechanisms and some possible scenarios for collaboration in the Etalier market.

title Design Algorithms after Le Corbusier
doi https://doi.org/10.52842/conf.acadia.2000.017
source ACADIA Quarterly, vol. 19, no. 4, pp. 17-24
summary Some views of design are the act as puzzle making, problem solving, evolutionary, and decision-making. All these focus on form generation as constructive, therefore characterizing design as a path-planning problem through a space of possibilities. Design problems consist sets of information divided into initial, intermediate, and goal states. Design in its simplest state consist of a set of operators, sequences (or paths) between initial and goals states. In this paper, I present design algorithms for Le Corbusier because of his distinct compositional techniques particularly for his “White Villas” in which some elements have been identified to recursively occur.

summary The goal of this paper is to define the processes that enable the simulation of an autonomous pedestrian’s journeys in confined spaces; and to determine their paths beginning with random processes under preset parameters in a generic fashion as well as doing so in a manner independent from walking movement. We present a conceptual model designed to generate pedestrian journeys, taking into account the focuses of attraction and their influence in the paths taken. In order to implement this model, we add to an architectural blueprint the elements necessary to recognize the geometric characteristics of the World (Limits, Focuses and Portals) that affect the displacements of pedestrians. These characteristics enable us to determine the paths to be taken in the World. The issues of the simulation (the position that each pedestrian occupies for unit of time) can be used by other applications, to generate animations or to verify critical situations.

title GA2: a Programming Environment for Abstract Generative Fine Art
source International Conference on Generative Art
summary Fine artists looking to use computers to create generative works, especially those artists inclined towards abstraction, often face an uncomfortable choice in the selection of software tools. On the one hand there are a number of commercial and shareware programs available which implement a few techniques in an easy to use GUI environment. Unfortunately such programs often impose a certain look or style and are not terribly versatile or expressive. The other choice seems to be writing code from scratch, in a language such as c or Java. This can be very time consuming as every new work seems to demand a new program, and the artist's ability to write code can seldom keep pace with his ability to imagine new visual ideas. This paper describes a software system created by the author called GA2 which has been implemented in the Matlab software environment. By layering GA2 over Matlab the artist can take advantage of a very mature programming environment which includes extensive mathematical libraries, simple graphics routines, GUI construction tools, built-in help facilities, and command line, batch mode, and GUI modes of interaction. In addition, GA2 is very portable and can run on Macintosh, Windows, and Unix systems with almost no incremental effort for multi-platform support. GA2 is a work in progress and an extension of the completed GA1 environment. It is medium independent, and can be used for all manner of image, animation, and sound production. GA1 includes a complete set of genetic algorithm operations for breeding families of graphical marks, a database function for managing and recalling various genes, a set of statistical operations for creating various distributions of marks on a canvas or animation frame, a unique Markov-chain-likeoperator for generating families of visually similar lines or paths, and a complete L-system implementation. GA2 extends GA1 by adding more generative techniques such as tiling and symmetry operations, Thom's cusp catastrophe, and mechanisms inspired by complexity science notions such as cellular automata, fractals, artificial life, and chaos. All of these techniques are encapulated in genetic representations. This paper is supplemented with examples from the authors art work, and comments on the philosophy behind this method of working, and its relation towards the reinvigoration of abstraction after post-modernism.

summary Cyberspace is a space for poetry. Cyberspace is a space waiting to be designed. The computer screen presents us an empty space, that appears without restrictions, thus unleashing poetic thinking, a space of art. Poetry is a hypertext, where words and spaces overlap, subdivide and interconnect. Meanings overlap and multiply. Cyberspace is a space for information. Daily we are witnessing how the virtual environment is becoming the most important media of information, mainly through the use of the internet. “Information” is used here as data, that includes all types of text, image, object, sound or video. Cyberspace gives us new possibilities to represent and visualize information in alternative ways. The hypothesis consists in use cyberspace to communicate information by poetic paths.

With the participation of teachers and professionals in the field of graphic design, fine arts, the cinema, TV, music, system programming and literature, a product has been devised, called “Maybe Tomorrow...” It is an interactive novel constructed on CD-ROM support. It is based on an original narration, developed around four stories that take place in the city of Montevideo. Each story has a different image treatment which responds to the use of different audiovisual languages. The reading of this interactive novel offers different trajectories, making the navigation in diverse ways possible. In this way, the reader constructs the meaning of the narration as he/she advances in the reading.

summary Hospitalization is, for the patient, a neuropsychophysiological stressor, thus pertinent theories point to architectural stimuli as a tool for the homeostasis restoration and consequent well-being. Furthermore, they compile advantages to the patients’ treatment and highlight, mainly, the natural environments benefits, which is elucidated by the Biophilia theory. Through literature review and analysis of applied research in national and international hospitals, extracted from indexing databases of scientific production in the 2000-2020 timeframe, it was found that these areas [a] promote stimuli that enhance emotions and positive feelings; [b] act to restore stress and anxiety; [c] reduce pain, analgesic intake and length of stay; and [d] increase patient satisfaction. By sharing the results of this research, the objective is, in addition to stimulating future research on the organism behavior in the environments, to indicate perspectives for hospital ambiences.

title Swarm modelling. The use of Swarm Intelligence to generate architectural form

summary In general the paper discusses the morphogenetic properties of swarm behaviour, and presents an example of mapping trajectories in the space of forms onto 3d flocking boids. This allows the construction of a kind of analogue to the string writing genetic algorithms and Genetic programming that are more familiar, and which have been reported by CECA. Earlier work with autonomous agents at CECA were concerned with the behaviour of agents embedded in an environment, and interactions between perceptive agents and their surrounding form. As elaborated below, the work covered in this paper is a refinement and abstraction of those experiments. This places the swarm back where perhaps it should have belonged, into the realms of abstract computation, where the emergent behaviours (the familiar flocking effect, and other observable morphologies) are used to control any number of alternative lower level morphological parameters, and to search the space of all possible variants in a directed and parallel way.

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 study of a cyberuniversity derives from an analogy between real urban space and its virtual "substitution". It represents an attempt to balance some views, which seems to be contrary, exclusive, but they are just parts of the same wholeness. Especially the notion of a cyber society is lately considered such an exaggeration, that it is possible to forget the meaning of a real life experience and interactions, which are already threatened. One should contribute to the awarness that is used in such a comparison, it is "just" an analogy, not a real similarity. At the same time it is possible to point out some limitations of a cyberspace and indicate a more realistic view of the meaning of cyber communities. Awarness of the development processes could help to find a balance between reality and virtuality, using cyberfacilities not to destroy us (our identity) but to improve the quality of our (real) life.

summary Architects are visual learners. The Internet has enabled interactive learning tools that can be used to assist in visual thinking of structural concepts, especially at the introductory levels. Here, we propose a visual approach for understanding structures through a series of interactive learning modules, or ’gizmos’. These gizmos, are the tools that the student may use to examine one structural concept at a time. Being interactive, they offer many more possibilities beyond what one static problem can show. The approach aims to enhance students’ visual intuition, and hence understanding of structural concepts and the parameters affecting design. This paper will present selected structural gizmos, how they work, and how they can enhance structural education for architects.

summary Founded in 1995 LAB[au], laboratory for architecture and urbanism, links theoretic research LAB[a+u] to concrete works of conception and realisations LA.BAU. LAB[au] elaborates a “hyperdesign” investigating the implications of new technologies of communication and computation in spatiotemporal and social processes and their forms of representation as architecture and urbanism. The transposition of the hypertext model to architectural and urban concepts question the mutation of the spatial and semantic construct of space. The definition of architecture as a code is based on “glocal” systems according to the processes of computation and communication.
