title	Views on architecture: Different abstraction layers of building information imply special working methods and interaction metaphors to support a variety of courses of action
source	SIGraDi 2016 [Proceedings of the 20th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Argentina, Buenos Aires 9 - 11 November 2016, pp.584-589
summary	In the early design phases, designers usually only have a vague idea of the building they are designing. Different aspects of potential design variants need to be tested, assessed and compared with one another. The ability to consider design variants in different ways – based on floor plan, schematic concept, section or 3D visualization, for example – helps to identify problems as well as reveal areas of potential. This paper describes software prototypes developed to help designers input and present different levels of abstraction. The transformations between these levels of abstraction reveal new solutions and make designers aware of issues that need to be considered during the design process.

title	Mobile Application to Collect Information About Architecture to Obtain a Collective Knowledge Base: 'ar:searchbox.app'
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 375-382
summary	During the early stages of the architectural design process, students and architects seek information for inspiration, and to evaluate design ideas or similar solutions. An essential part of design education therefore involves building up a knowledge base of already built or designed buildings. Most students gather such information by visiting or researching building designs, for example through photos taken on design studio field trips. These photos are used for studio work or archived for later use. The “ar:searchbox.app” aims to support this in two ways. Firstly, by supporting easy mobile information acquisition and sharing, as well as the semi-automatic derivation of high quality metadata; and secondly, by employing urban environment sensitive search and similarity-based browsing strategies to support mobile education as well as a web-based access to the information. To provide long-term access and to establish an information base that is not restricted to a single design studio, the “ar:searchbox.app” builds on our previous “ar:searchbox” project which uses a central media server called “mediaTUM” that provides a handling concept for flexible metadata schemas and scalable infrastructures.

title	Representational Issues in Learning Systems
source	IEEE Computer. October, 1983. vol. 16: pp. 47-51 : ill. includes bibliography
summary	One of the central issues in artificial intelligence involves learning -- the modification of behavior through the acquisition of knowledge. The way knowledge is represented impacts the way learning occurs and indeed may determine whether learning can occur at all. The issues of learning and representation have many potential interactions. The purpose of this paper is to illuminate representational problems that may not have occurred to researchers setting out to construct self-modifying systems, and to suggest some possible solution to these problems

title	Artificial Life
source	Boden, M. A. (1996). The Philosophy of Artificial Life, 39-94.New York and Oxford: Oxford University Press
summary	Artificial Life contains a selection of articles from the first three issues of the journal of the same name, chosen so as to give an overview of the field, its connections with other disciplines, and its philosophical foundations. It is aimed at those with a general background in the sciences: some of the articles assume a mathematical background, or basic biology and computer science. I found it an informative and thought-provoking survey of a field around whose edges I have skirted for years. Many of the articles take biology as their starting point. Charles Taylor and David Jefferson provide a brief overview of the uses of artificial life as a tool in biology. Others look at more specific topics: Kristian Lindgren and Mats G. Nordahl use the iterated Prisoner's Dilemma to model cooperation and community structure in artificial ecosystems; Peter Schuster writes about molecular evolution in simplified test tube systems and its spin-off, evolutionary biotechnology; Przemyslaw Prusinkiewicz presents some examples of visual modelling of morphogenesis, illustrated with colour photographs; and Michael G. Dyer surveys different kinds of cooperative animal behaviour and some of the problems synthesising neural networks which exhibit similar behaviours. Other articles highlight the connections of artificial life with artificial intelligence. A review article by Luc Steels covers the relationship between the two fields, while another by Pattie Maes covers work on adaptive autonomous agents. Thomas S. Ray takes a synthetic approach to artificial life, with the goal of instantiating life rather than simulating it; he manages an awkward compromise between respecting the "physics and chemistry" of the digital medium and transplanting features of biological life. Kunihiko Kaneko looks to the mathematics of chaos theory to help understand the origins of complexity in evolution. In "Beyond Digital Naturalism", Walter Fontana, Guenter Wagner and Leo Buss argue that the test of artificial life is to solve conceptual problems of biology and that "there exists a logical deep structure of which carbon chemistry-based life is a manifestation"; they use lambda calculus to try and build a theory of organisation.

title	Craft and Digital Consequences - Micro-Hybrid Explorations at (Full) Scale
doi	https://doi.org/10.52842/conf.ecaade.2017.2.327
source	Fioravanti, A, Cursi, S, Elahmar, S, Gargaro, S, Loffreda, G, Novembri, G, Trento, A (eds.), ShoCK! - Sharing Computational Knowledge! - Proceedings of the 35th eCAADe Conference - Volume 2, Sapienza University of Rome, Rome, Italy, 20-22 September 2017, pp. 327-336
summary	This paper presents a comprehensive project-based research investigation that uses both drawing and modeling to challenge conventional design space. Situated at the University of Kentucky-College of Design Applied Computation Center (CoDACC) in Lexington, KY, this independent undergraduate research project reveals an immersive framework that develops, evaluates, and assesses both graphic and three-dimensional information at full scale. This research provides a framework that seamlessly negotiates analog and digital means of communication and prototyping. This paper outlines the micro-hybrid design process to frame topics germane to today's increasingly complex built environment. The paper also includes the micro-hybrid decision-making matrix and discusses the evaluation of the produced artifacts. The research demonstrates how the micro-hybrid process can reveal both the craft and consequences related to design experimentation and construction. Further, the micro-hybrid process has been shown to deepen a student's understanding of the composition of materials and a student's awareness of forces and structural loads, which in turn has produced a deeper appreciation for the principles of structures and an improved mastery of manufacturing jointing details.

title	The Creative Aspects of CAD: A Possible Approach
source	Design Studies, (8) 2, pp. 76-81
summary	Whilst it is common ground that CAD systems can help designers in many areas, what is not clear is the extent of assistance that can be provided in the creative aspects. A possible approach to creative designing with computers is that of `prototype modification'. It is possible to see all designing in terms of this approach. The distinction between innovative design and design by modification results only from the quality and nature of the prototypes and modifications involved.

title	Knowledge for Designers
source	Architect`s journal. England: February, 1984. vol. 179: pp. 55-58
summary	The first of two articles discussing expert systems. Both design and construction are carried out within the framework of empirical rules and regulations designed more for ease of implementation and checking than scientific validity. On completion of a building, little follow up research is done on the way it is used or on the way in which the assumption made in its design are borne out in practice. This present two problems: How to make information from disparate sources easily available to designers and constructors, and how to make them aware that they need this information. This paper describes how a special type of computer programming might assist in solving these problems

title	Requirements for Knowledge-based Systems in Design
source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 120-127
summary	Even from the comparatively small amount of work that has been done in this area it is already clear that expert systems can be of value in many architectural applications. This is particularly so in those applications involving what broadly can be called, 'classification' (such as fault diagnosis, testing for conformity with regulations and so on). What we want to look at in this chapter are some of the developments in knowledge-based systems (KBS) which will be needed in order to make them more useful in a broader application area and, especially, in creative design. At the heart of these developments will be two things: (1), more appropriate methods of representing knowledge which are as accessible to humans as they are to computers; and (2), better ways of ensuring that this knowledge can be brought to bear exactly where and when it is needed. Knowledge engineers usually call these elements, respectively, 'knowledge representation' and 'control'.

source	Architectural Education and the Information Explosion [eCAADe Conference Proceedings] Zurich (Switzerland) 5-7 September 1987.
summary	Computers have been potentially able to assist designers in their work for almost thirty years. A few pioneers have been using them for this purpose for more than twenty years but it is only in the last seven or so that use has become really widespread. Undoubtedly, the most widespread use of computers in architectural practice is for making production drawings - which they can do with an accuracy, speed and reliability difficult to achieve by manual means. But this use does not even begin to exploit the full possibilities that computer aided design opens up. What I want to do here is to introduce these possibilities and discuss what impact they might have on the way we design in the immediate future.

title	Structured Graphics for Distributed Systems
source	ACM Transactions on Graphics January, 1984. vol. 3: pp. 23-51 : ill.
summary	includes bibliography: pp. 48-51. One of the most important functions of an intelligent workstation is to provide a state-of-the-art user interface to distributed resources. One aspect of such an interface is virtual terminal support for both local and remote applications with a range of requirements, including graphics. To ensure good response for remote applications in particular, the bulk of user interaction must be handled local to the workstation. Therefore, the terminal management software on the workstation must provide object modeling as well as viewing facilities, in contrast to most contemporary graphics systems. One way of doing this is to support structured display files. It is equally important to support simultaneous access to multiple applications ; thus the terminal management software must provide window system facilities. Lastly, since the terminal management software should present a common interface to both local and remote applications, the workstation itself should be regarded as a multifunction component of the distributed system and not strictly as a terminal or a personal computer. This paper presents the system architecture and protocols necessary to achieve these goals and evaluates an existing implementation

title	Tangential surfaces to optimize digital manufacturing of complex shapes

summary	The knowledge of geometric-mathematical rules allows to solve several problems about complex systems design and manufacturing. Geometric genesis of surfaces and their properties represent the main basis to solve both constructive and measurement problems. A developable surface can be manufactured starting from a flat strip, using a flexible and non- deformable material. Geometry studies properties that don't change and, therefore, the shape of the strip to obtain a certain configuration after a series of rigid movements. Our goal is to test different approches (Additive Manufacturing vs Subtractive Manufacturing) to manufacture a lamp using a tangential developable surface.

source	CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 127-136
summary	The architectural design process has more than one participant. Each participant has his own way of approaching the information embedded in a design. In the future the CAAD systems of these participants must be able to communicate and exchange information. For a communication of this kind there must be a common ground, a frame of reference, in which these different points of view can be expressed. This frame of reference or model must support participants accessing the same information with different objectives and for different purposes. We shall propose such a model based on research results obtained by the analysis of architectural knowledge and designs. The model incorporates certain aspects drawn from AI.

source	Proceedings of the 8th European Architectural Endoscopy Association Conference
summary	The architectural space formed within this or that type of culture is observed. The searching of the space basement of the traditional cultures and the modern man-caused civilizations is accented. In both cases the space organization is a reflection of a certain world outlook system. There are some examples of architectural reconstruction of lost space structures of some traditional cultures with using of modern ones within the techno-culture technical devices.

title	Integrative Fabrication of Sandwich Shells. An integrative approach to design of robotically fabricated wood- based sandwich segmented shells
doi	https://doi.org/10.52842/conf.acadia.2018.358
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 358-365
summary	This paper presents the development of an integrative and adaptive robotic fabrication process for the production of wooden-based segmented shells of variable thickness. A material and construction process is presented whereby an industrial robot with a two-degree of freedom end-effector acts as active form-work, positioning flexible strips of plywood so they can be assembled into a structurally performative configuration and then filled with a polyurethane expandable foam. The resulting material system is a structurally performative and doubly curved sandwich composite which performs well in bending. This paper discusses the construction process and the material system, methods for structural analysis, an adaptive robotic fabrication process, as well as a computational design tool which integrates material constraints, robotic constraints, and structural performance. The resulting construction system expands the design possibilities for robotic fabrication in wood, particularly as a viable material system for implementation directly in an on-site condition.

summary	Renowned Architecture schools are acting globally by means of international workshops. In these, new methodo- logies of digital parametric representations are applied in urban interventions. We bring forward an inflatable solution for sheltering a sports event, held under a viaduct. In this case, parametric technology was employed in the design, with the use of digital fabrication. Several other interventions were proposed for the same space chosen for the action of a multidisciplinary group of professors. Differently from government actions that usually focus on the removal of social problems this workshop sought a solution through technology, new materials and parametric design.

title	Teaching digital fabrication in the post-industrial era
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The creation process of a product is a work of immersion and concentration, and is, seldom linear. A primary concept most likely will undergo modifications during the process. In what concerns teaching, a great number of Brazilian higher education institutions act exclusively on the formation of students as specialists in the creation of primary concepts. As for the process of refining an idea, as in prototype production and observation, this phase will only be learned and understood on the job market. Nowadays, new methodologies for digital fabrication put into evidence other strategies resulting from post-industrial production.

title	The S. Pedro da Cova Community Knowledge Centre, a local example of empowerment through technology

summary	S. Pedro da Cova (Gondomar), located ten kilometres from the city centre of Porto (Portugal), is considerate a depressed territory, with a large spectrum of social, economic and urban problems, but also with local positive aspects capable to reach the different development opportunities.In the ambit of the regeneration process for this area, the local authority draw a strategy based in the empowerment of the citizens, where the Information Communication Technologies (ICT’s) assumed a major role. With this purpose, it was intended to build a Community Technology Centre for the disfavoured children. From the building construction till the first activities, it is our conviction that to break the differences between the have and the have not’s it will be very important to conciliate the new technologies and the local characteristics. The children will be the active agents in the dissemination of the project through the development of the different activities, sensitising the families to adopt a healthy life and announce situations of risk, for example. To validate the project will be created an permanent observatory that propose a moment of reflection and auto-valuation about the evolution of the different activities, thechanges to do, and the identification of new problems and the redefinition of new methodologies. The aim of the article is not only to show the positive aspects, indeed significant, but also to bring into discussion some questions; in order to understand the possibility of defining an empowerment strategy based in the ICT’s. How to conciliate the individualperspectives of the future into a common objective? How to show to all community that information and knowledge are fundamentalto build a more liveable and equity neighbourhood? How to transfer the results to a larger strategy for the entire city? And, at theend, how to explain that people is the most important "infrastructure" to build a better future?

summary	The growth of urban settlements is a phenomenon on the rise. It is expected that more than 70% of the people will live in urban settlements by 2050. To be able to tackle and embrace this growth, we need alternative tools that help us to face these challenges. On this framework, this proposal aims to raise the paradigm of how the information can be gathered and used to equilibrate urban systems in terms of planning concerning the distribution of resources. To achieve this goal, the exchange of data through an organic system of biochemical interaction network is proposed.
