title An Automatic Algorithm Designer : An Initial Implementation
source Design Research Center, CMU, May, 1983. 10 p. includes bibliography
summary This paper outlines a specification for an algorithm-design system (based on previous work involving protocol analysis) and describes an implementation of the specification that is a combination frame and production system. In the implementation, design occurs in two problem spaces: one about algorithms and one about the task domain. The partially worked out algorithms are represented as configurations of data-flow components. A small number of general purpose operators construct and modify the representations. These operators are adapted to different situations by instantiation and means-ends analysis rules. The data-flow space also includes symbolic and test-case execution rules that drive the component-refinement process by exposing both problems and opportunities. A domain space about geometric images supports test-case execution, domain-specific problem solving, recognition and discovery

title Programming framework for architectural design ANAR+: Object oriented geometry
source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 771- 785
summary From the recent advent of scripting tools integrated into commercial CAAD software and everyday design practice, the use of programming applied to an architectural design process becomes a necessary field of study. The presented research explores the use of programming as explorative and reflexive medium (Schön, 1983) through the development of a programming framework for architectural design. Based on Java, the ANAR+ library is a parametric geometry environment meant to be used as programming interface by designers. Form exploration strategies based on parametric variations depend on the internal logic description, a key role for form generation. In most commercial CAD software, geometric data structures are often predefined objects, thus constraining the form exploration, whereas digital architectural research and teaching are in need for an encompassing tool able to step beyond new software products limitations.

title Simulation of the Emergency Evacuation of Buildings in the Event of Fire
source Proceedings of the International Conference eCAADe [European Computer Aided Architectural Design Education] Brussels (Belgium) 1983, pp. II.10-II.22
summary The paper describes an application of CAAD techniques by Final Year architecture students using the computer program AIR-Q to dynamically simulate the emergency evacuation of people from a multi-storey department store. This is presented in the context of a fire emergency and reference made to the local Building Regulations which govern the size and location of fire exits. It is suggested that the technique not only provides students and designers with an easily assimilated understanding of the consequences of design decisions but also allows alternative design solutions to be quickly compared in a search for the optional design strategy. The exercise also demonstrates, to the students, the logic behind the rules contained in the Fire Regulations while demonstrating possible weaknesses and inadequacies of the empirical approach that these regulations are constrained to adopt.

title Computers in Architectural Education
source Teaching and Research Experience with CAAD [4th eCAADe Conference Proceedings] Rome (Italy) 11-13 September 1986, pp. 71-77
summary Throughout Europe there is a rapidly growing volume of initiatives towards integrating computer aids within all aspects of education. In architectural education, the support offered by these initiatives presents a double-edged sword. On the one hand it is gratifying to see the work of almost two decades of CAAD research bearing fruit and the concepts gaining recognition by the profession. On the other hand the resulting pressures on the few individuals with the necessary knowledge to implement the teaching will stretch many to breaking point. Where resources are so limited it is crucial to clarify the needs and objectives and, thereby, more effectively direct resources. These needs will change over time and, in the world of computers, the means are also changing rapidly as hardware and software improves. This paper therefore outlines a scenario which I believe is relevant at this point in time but the background is constantly changing and I offer no apologies for any shift in emphasis since my last presentation of this topic in 1983.

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 Integration of Solid Modeling and Data Base Management for CAD/CAM
source ACM IEEE Design Automation Conference Proceedings (20th : 1983 : Miami Beach, Florida). pp. 367-373 : ill
summary For the fast growing CAD/CAM technologies, geometric solid modeling plays one of the most important roles. In order to satisfy a variety of engineering applications, an integrated database management system based on solid modeling is highly desirable. In the proposed approach, a concise object representation scheme, Constructive Solid Geometry (CSG), is adopted as the basis for database design. The underlying generic relational model is found to be more adequate than the conventional relational model in characterizing the embedded data abstraction. A systematic method is devised for converting the CSG scheme into a generic model based on the BNF grammar which depicts the CSG scheme. A relational query language, SEQUEL, has been modified to define, control, and manipulate the flat relations which represent the highly structural generic model

title An Analysis and Algorithm for Polygon Clipping
source Communications of the ACM November, 1983. vol. 26: pp. 868-877 : ill. includes bibliography.
summary (This is one of the two standard algorithms for clipping. The other is the Sutherland-Hodgman reentrant algorithm). The process of polygon clipping is analyzed and the understanding gained thereby forms the foundation of a very direct algorithm. Each edge of the input polygon is considered to be a vector and is then extended to be a line of infinite extent. The boundary line segments of the clip window are extended in a similar fashion to become boundary lines. The intersection points of an extended edge with the boundary lines are identified as entry or exit points. It is observed that these entry and exit points can be used to characterize the visibility status of the edge. Not only might the edge have a visible segment, but it can also induce the inclusion in the output polygon of a vertex at a corner of the clip window called a turning vertex. To quantify the visibility conditions, the edge is written in parametric form. The possible contributions (including nil) that can be provided to the output polygon by a particular edge are established. This analysis is then embedded in an algorithm. An arbitrary example input polygon is given and the output of the algorithm is shown. The execution time for this example using this algorithm is measured to be half of what is required by the standard Sutherland-Hodgman reentrant polygon clipping algorithm

title Efficiency of Model Endoscopic Simulation - An Experimental Research at the University of Stuttgart
source Endoscopy as a Tool in Architecture [Proceedings of the 1st European Architectural Endoscopy Association Conference / ISBN 951-722-069-3] Tampere (Finland), 25-28 August 1993, pp. 31-34
summary At the Institute of Urban Planning at the University of Stuttgart early experiments were made with the help of endoscopes in the late 1970’s. The intention was to find new instruments to visualize urban design projects. The first experiment included the use of a 16 mm film of a 1:170 scale model of the market place at Karlsruhe, including design alternatives (with trees, without trees etc). The film was shown to the Karlsruhe authorities, who had to make the decision about the alternatives. It was said, that the film gave a great help for the decision-making and a design proposition had never before been presented in such understandable way. In 1975-77, with the support of the Deutsche Forschungsgemeinschaft (German Research Foundation) an investigation was carried out into existing endoscopic simulation facilities, such as those in Wageningen, Lund and Berkeley. The resulting publication was mainly concerned with technical installations and their applications. However a key question remained: ”Can reality be simulated with endoscopy?” In 1979-82, in order to answer that question, at the Institute was carried out the most extensive research of the time, into the validity of endoscopic simulation. Of special importance was the inclusion of social scientists and psychologists from the University of Heidelberg and Mannheim. A report was produced in 1983. The research was concerned with the theory of model simulation, its ways of use and its users, and then the establishment of requirements for effective model simulation. For the main research work with models or simulation films, psychological tests were developed which enabled a tested person to give accurate responses or evidence without getting involved in alien technical terminology. It was also thought that the use of semantic differentials would make the work imprecise or arbitrary.

summary In contrast to conventional database systems, AI systems require a knowledge base with diverse kinds of knowledge. These include, but are not limited to knowledge about objects, knowledge about processes, and hard to represent common sense knowledge about goals, motivations, causality, time, actions etc. This article is an introduction to a special issue in which 15 articles contributed by a broad spectrum of researchers discuss various aspects of knowledge representation. It gives some background and context to these articles by mapping out the basic approaches to knowledge representation that have developed over the years

title Justifying Designs
source Proceedings of the International Conference eCAADe [European Computer Aided Architectural Design Education] Brussels (Belgium) 1983, pp. 0.1-0.9
summary A distinction is made between non-justified (not 'unjustified') and justified designs. A good justification requires that a description of the solution space and a rule for selecting one solution should be given. The old but rarely used concept of the planning model is described and it is stressed that it is a useful aid when justifying design decisions. A simple example is presented to illustrate the method. It is pointed out that the use of computers can be helpful when dealing with large solution spaces, complicated evaluation rules and high demands on the quality of the justification. An increasing demand for design justification is observed, which may result in increased computer application. The hope is expressed that planning models will be used in this connection for better communication.

title Source Studio: Teaching Programming For Architectural Design
source T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary The architectural studio framework presented here is based on the use of programming as central form generation reflexive medium (Schon, 1983). Its aim is to teach architectural design while introducing a different approach toward computer tools by enabling students to fully explore variations in their designs through the use of coding for form definition. It proposes the students to reflect on their design process through its confrontation to algorithmic formalization (Mitchell 1990). This results in exercising the synthetic re-thinking of their initial sketch intents to comply with the difficult task of fitting the language syntax. With the proliferation and constant replacement of computer tools among the architectural practice, a shift appears in the attitude towards introducing students to different tools: studio teaching is branded by specific software platforms advocated by the teaching team. A lack of generalized view, independent of commercial CAD software, is problematic for the definition of new teaching tools suited for this constantly evolving situation (Terzidis, 2006).

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 An Educational Strategy for CAAD and its Implementation in a New System with a Sophisticated Interface
source Proceedings of the International Conference eCAADe [European Computer Aided Architectural Design Education] Brussels (Belgium) 1983, pp. I.1-I.19
summary Reasons are examined for the slower uptake of CAD in architecture than in engineering. An appropriate response to Computer-Aided Architectural Design is overdue from the educational sector. Schools of Architecture should put CAAD to the forefront in their plans, taking an ambitious long-term view and aiming for high-quality system design to anticipate the industry's drive to produce first-class equipment progressively more cheaply. Schools should press for changes in the way facilities are supplied to them. They should discard obsolete software, buy software commercially, stick to what they can do best, and plan for concomitant changes across the curriculum. A new CAAD system with the emphasis on the design interface being implemented in UCD School of Architecture is briefly described.

title Organization of a Structural Design Database
source Electronic Computation Conference Proceedings (8th : 1983 : Houston, TX). American Society of Civil Engineers, pp. 559-571. CADLINE has abstract only
summary This paper proposes a database schema that supports structural engineering design of buildings. An evaluation and comparison of hierarchical, network, and relational databases shows that relational databases are especially suited to a structural engineering design database. The proposed database schema represents the complex relationships between the components of a building-design database. The schema consists of a structural system hierarchy that relates abstract database components to basic building elements. In addition, it combines topology with attributes to achieve an integration that allows the representation of a broad range of common building configurations and structural systems. The user can combine a basic set of constructs to generate either a general or a very detailed description of a structure. The high degree of integration of topology and attributes yields a database that possesses desirable relational characteristics. The database provides efficient access to components based both on their location and on their attribute values. It also allows the user to add, delete, retrieve, and modify database components and values. The versatility and flexibility of the relational model make it a useful tool for managing building engineering data

title Solid Model Input Through Orthographic Views
source Computer Graphics, Vol 17, No 3, July
summary This paper describes the results of basic studies on procedures for creating solid models of component geometry from two-dimensional orthographic projections. An interactive graphic program was developed to allow the input of three orthographic views of a component geometry by digitizing from a drawing. The views may contain straight lines and circular arcs, solid or dashed. No restrictions are placed on the order or direction of lines and arcs in any view. Using an extension of the Wesley-Markowski procedure, the program constructs a three-dimensional solid model of the object. When the projections are ambiguous, multiple solid models are produced. The solid model may contain planar, cylindrical, conical, spherical and toroidal surfaces. Topological information of the solid model is sotred in a winged edge sturcture. Geometric information is stored as vertex coordinates and surface equations.
