XVI, no. 1, pp. 3-27
summary	It is argued that readers are likely to carry away from Donald Knuth's article 'The Concept of a Meta-Font' a falsely optimistic view of the extent to which the design of typefaces and letterforms can be mechanized through an approach depending on describing letterforms by specifying the settings of a large number of parameters. Through a comparison to mathematical logic, it is argued that no such set of parameters can capture the essence of any semantic category. Some different ways of thinking about the problem of the 'spirit' residing behind any letterform are suggested, connecting to current research issues in the field of artificial intelligence

title	Cognitive Biases - The case of tropical architecture
source	Delft University of Technology
summary	This dissertation investigates, i) How cognitive biases (or illusions) may lead to errors in design thinking, ii) Why architects use architectural precedents as heuristics despite such possible errors, and iii) Develops a design tool that can overcome this type of errors through the introduction of a rebuttal mechanism. The mechanism controls biases and improves accuracy in architectural thinking. // The research method applied is interdisciplinary. It employs knowledge from cognitive science, environmental engineering, and architectural theory. The case study approach is also used. The investigation is made in the case of tropical architecture. The investigation of architectural biases draws from work by A. Tversky and D. Kahneman in 1982 on “Heuristics and biases”. According to Tversky and Kahneman, the use of heuristics of representativeness (based on similarity) and availability (based on ease of recall and imaginability) for judgement of probability can result in cognitive biases of illusions of validity and biases due to imaginability respectively. This theory can be used analogically to understand how errors arise in the judgement of environmental behaviour anticipated from various spatial configurations, leading to designs with dysfunctional performances when built. Incomplete information, limited time, and human mental resources make design thinking in practice difficult and impossible to solve. It is not possible to analyse all possible alternative solutions, multiple contingencies, and multiple conflicting demands, as doing so will lead to combinatorial explosion. One of the ways to cope with the difficult design problem is to use precedents as heuristic devices, as shortcuts in design thinking, and at the risk of errors. This is done with analogical, pre-parametric, and qualitative means of thinking, without quantitative calculations. Heuristics can be efficient and reasonably effective, but may not always be good enough or even correct, because they can have associated cognitive biases that lead to errors. Several debiasing strategies are discussed, and one possibility is to introduce a rebuttal mechanism to refocus the designer’s thinking on the negative and opposite outcomes in his judgements, in order to debias these illusions. The research is carried out within the framework of design theory developed by the Design Knowledge System Research Centre, TUDelft. This strategy is tested with an experiment. The results show that the introduction of a rebuttal mechanism can debias and improve design judgements substantially in environmental control. The tool developed has possible applications in design practice and education, and in particular, in the designing of sustainable environments.

title	A Microprocessor Revolution and the World Distribution of Income: A General Equilibrium Approach
source	International Political Science Review. 1982. vol.3: pp. 434- 454 ; ill. includes bibliography
summary	This article shows that even if the world economy is able to withstand and surmount the present world crisis, the combination of market forces and rapid technical change that would be the result of a microprocessor revolution will give rise to large shifts in the distribution of income within and between both rich and poor countries. Some developed and developing economies may be unable to join the move to new technologies. In a world governed by only economic forces, all countries, whether they choose to adopt new systems of production or not, will be affected. Indeed, whatever their degree of involvement, all countries are beginning to feel in varying degrees the chain reaction that reverberates through and between all sectors of their domestic and the world economies. To gain insights into interrelations between technological change and global markets, this article uses a special type of model -- a general equilibrium model -- that enables the study to focus on exactly these variables

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	Recent Developments in Representation in the Science of Design
source	9 p. : ill. Pittsburgh: Design Research Center, CMU, April, 1982. includes bibliography
summary	A recent goal in computer aided design is the representation of a design artifact in a form sufficient to support all analyses and to determine that the design is realizable. In this paper, the implications of the development of computer representations for design specifications are reviewed, some components of a theory of design representations are discussed, and the benefits of such a theory outlined

summary	A description is given of the design and implementation of a Pascal program for the stepwise visible execution of other Pascal programs. This system operates at the source code level by inserting additional statements into the user program. This additional code causes the stepwise execution of the user program, as well as the display of the statement currently executed together with variables whose values have just changed. This system is intended as both a teaching aid and a debugging aid. It enables the user to investigate the dynamic properties of his program

title	What is eCAADe?
doi	https://doi.org/10.52842/conf.ecaade.1984.x.d0s
source	The Third European Conference on CAD in the Education of Architecture [eCAADe Conference Proceedings] Helsinki (Finnland) 20-22 September 1984.
summary	The main interest of the organisation is to improve the design, teaching. The design remains the core of the professional education, while computer science can support a better understanding of the design methods. Computers should amplify the human capabilities like engines allowed to carry higher forces, radio and television enabled communication over larger distances and computers today should aid the human intellectual activities, to gain a better insight in design methodology, to investigate the design process.Design research should study more extensively how buildings behave, the integration and interaction of different disciplines which contribute to the optimization of a design and the design criteria. Computers could increase the possibility to satisfy building regulations, to access and update information, to model the design process and to understand how decisions affect the building quality (functional and economical as well as formal aspects). More effort and money should be spent on this research. The organisation has been sponsored by the EEC for bringing CAAD (Computer Aided Architectural Design) educational material at the disposal of the design teachers. The Helsinki conference is the third European meeting (after Delft 1982 and Brussels 1983) which concentrates on information and experience exchange in CAAD-education and looks for common interests and collaboration. A specific joint study program works on typical audiovisual material and lecture notes, which will be updated according to teacher's needs. A demand has been done to implement an integrated CAAD package. eCAADe focuses to integrate computer approaches across country boundaries as well as across disciplinary boundaries, as to reach a higher quality of the design education.

title	The Knowledge Level
source	[2]. 46 p. : ill. Design Research Center, CMU, April, 1982. DRC-15-15-82. includes bibliography
summary	As the first AAAI Presidential Address, this paper focuses on a basic substantive problem: the nature of knowledge and representation. There are ample indications that artificial intelligence is in need of substantial work in this area, e.g., a recent SIGART special issue on Knowledge Representation edited by Ron Brachman and Brian Smith. The paper proposes a theory of the nature of knowledge, namely, that there is another computer system level immediately above the symbol (or program) level. The nature of computer system levels is reviewed, the new level proposed, and its definition is treated in detail. Knowledge itself is the processing medium at this level and the principle of rationality plays a central role. Some consequences of the existence of the knowledge level and some relations to other fields are discussed

title	Using Shadows in Finding Surface Orientations
source	61 p. : ill.` Pittsburgh, PA: Department of Computer Science, CMU, January, 1982. CMU-CS- 82-100
summary	Given a line drawing from an image with shadow regions identified, the shapes of the shadows can be used to generate constraints on the orientations of the surfaces involved. This paper describes the theory which governs those constraints under orthography. A 'Basic Shadow Problem' is first posed, in which there is a single light source, and a single surface casts a shadow on another (background) surface. There are six parameters to determine: the orientation (2 parameters) for each surface, and the direction of the vector (2 parameters) pointing at the light source. If some set of 3 of these are given in advance, the remaining 3 can then be determined geometrically

title	Hidden Line Elimination in Projected Grid Surfaces
source	ACM Transactions on Graphics. October, 1982. vol. 1: pp. 274-288 : ill. includes a short bibliography
summary	The hidden line and hidden surface problems are simpler when restricted to special classes of objects. An example is the class of grid surfaces, that is, graphs of bivariate functions represented by their values on a set of grid points. Projected grid surfaces have geometric properties which permit hidden line or hidden surface elimination to be done more easily than in the general case. These properties are discussed in this paper, and an algorithm is given which exploits them

title	Cognitive Biases and Precedent Knowledge in Human and Computer-Aided Design Thinking

summary	Cognitive biases (illusions) and potential errors can occur when using precedent knowledge for analogical, pre-parametric and qualitative design thinking. This paper refers largely to part of a completed research (Bay 2001) on how heuristic biases, discussed by Tversky and Kahneman (1982) in cognitive psychology, can affect judgement and learning of facts from precedents in architectural design, made explicit using a kernel of conceptual system (Tzonis et. al., 1978) and a framework of architectural representation (Tzonis 1992). These are used here to consider how such illusions and errors may be transferred to computer aided design thinking.

summary	The problem of heuristic biases (illusions) discussed by Tversky and Kahneman (1982) that can lead to errors in judgement by human designers, when they use precedent knowledge presented graphically (Bay 2001). A Cognitive framework of belief, goal, and decision, and a framework of representation of architectural knowledge by Tzonis are used to map out the problem of heuristic biases in the human mind. These are used to discuss what aspects of knowledge can be presented explicitly and digitally to users to make rebuttal more available for human thinking at the cognitive level. The discussion is applicable to both inductive and analytic digital knowledge systems that use precedent knowledge. This discussion is targeted directly at means of addressing bias in the human mind using digital means. The problem of human bias in machine learning and generalisation are discussed in a different paper, and the problems of international or non-intentional machine bias are not part of discussion in this paper.

title	A Generalization of Algebraic Surface Drawing
source	ACM Transaction on Graphics, vol. 1, no. 3, pp. 235-256, 1982
summary	The technology of creating realistic and visually interesting images of three- dimensional shapes is advancing on many fronts. One such front is the develop- ment of algorithms for drawing curved surfaces directly from their mathematical definitions rather than by dividing them into large numbers of polygons. Two classes of surfaces which have received attention are the quadric and the bivariate parametric surfaces. Bivariate parametric surfaces are generated by three func- tions of two variables (most popularly polynomials), as the variables take on different values. Algorithms dealing with such surfaces are due to Catmull; Lane, Carpenter, Whitted and Blinn; and Clark.
