title The logic of typed feature structures with applications to unification grammars, logic programs and constraint resolution
source Cambridge Tracts in Theoretical Computer Science, Cambridge University Press
summary This book develops the theory of typed feature structures, a new form of data structure that generalizes both the first-order terms of logic programs and feature-structures of unification-based grammars to include inheritance, typing, inequality, cycles and intensionality. It presents a synthesis of many existing ideas into a uniform framework, which serves as a logical foundation for grammars, logic programming and constraint-based reasoning systems. Throughout the text, a logical perspective is adopted that employs an attribute-value description language along with complete equational axiomatizations of the various systems of feature structures. Efficiency concerns are discussed and complexity and representability results are provided. The application of feature structures to phrase structure grammars is described and completeness results are shown for standard evaluation strategies. Definite clause logic programs are treated as a special case of phrase structure grammars. Constraint systems are introduced and an enumeration technique is given for solving arbitrary attribute-value logic constraints. This book with its innovative approach to data structures will be essential reading for researchers in computational linguistics, logic programming and knowledge representation. Its self-contained presentation makes it flexible enough to serve as both a research tool and a textbook.

title ClearBoard: A Seamless Medium for Shared Drawing and Conversation with Eye Contact Systems for Media-Supported Collaboration
source Proceedings of ACM CHI'92 Conference on HumanFactors in Computing Systems 1992 pp. 525-532
summary This paper introduces a novel shared drawing medium called ClearBoard. It realizes (1) a seamless shared drawing space and (2) eye contact to support realtime and remote collaboration by two users. We devised the key metaphor: "talking through and drawing on a transparent glass window" to design ClearBoard. A prototype of ClearBoard is implemented based on the "Drafter-Mirror" architecture. This paper first reviews previous work on shared drawing support to clarify the design goals. We then examine three metaphors that fulfill these goals. The design requirements and the two possible system architectures of ClearBoard are described. Finally, some findings gained through the experimental use of the prototype, including the feature of "gaze awareness", are discussed.

title Data Modeling Needs of Life Safety Code (LSC) Compliance Applications
source Mission - Method - Madness [ACADIA Conference Proceedings / ISBN 1-880250-01-2] 1992, pp. 177-185
doi https://doi.org/10.52842/conf.acadia.1992.177
summary One of the most complex code compliance issues originates from the conformance of designs to Life Safety Code (NFPA 101). The development of computer based code compliance checking programs attracted the attention of building researchers and practitioners alike. These studies represent a number of approaches ranging from CAD based procedural approaches to rule based, non graphic ones, but they do not address the interaction of the rule base of such systems with graphic data bases that define the geometry of architectural objects. Automatic extraction of the attributes and the configuration of building systems requires 11 architectural object - graphic entity" data models that allow access and retrieval of the necessary data for code compliance checking. This study aims to specifically focus on the development of such a data model through the use of AutoLISP feature of AutoCAD (Autodesk Inc.) graphic system. This data model is intended to interact with a Life Safety Code rule base created through Level5-Object (Focus Inc.) expert system.

Assuming the availability of a more general building data model, one must define life and fire safety features of a building before any automatic checking can be performed. Object oriented data structures are beginning to be applied to design objects, since they allow the type versatility demanded by design applications. As one generates a functional view of the main data model, the software user must provide domain specific information. A functional view is defined as the process of generating domain specific data structures from a more general purpose data model, such as defining egress routes from wall or room object data structure. Typically in the early design phase of a project, these are related to the emergency egress design features of a building. Certain decisions such as where to provide sprinkler protection or the location of protected egress ways must be made early in the process.

title Toward a procedure of computer simulation in the restoration of historical architecture
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary In the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

summary CAD systems regularly offer new techniques for the presentation of design proposals like computer-generated (stereo-) images, animations, holography and virtual reality. These techniques are mainly used for the presentation of a final design or for the presentation of buildings that have already been constructed. As in the course of time the quality of the CAD systems and their users have improved enormously, it is also possible to use these systems for the evaluation of several temporary design proposals during the design process. Since 'beautiful pictures' and 'wonderful animations' have already shown their great value when presenting a design, it is sometimes as if CAD systems are considered suitable for this propose only. Even new techniques like virtual reality systems seem to be valued only through the 'tinted glasses' of the presentation capabilities. Hardly any attention is paid to the possibilities that these new techniques offer as an instrument to support modelling and evaluation during the design process. This article will outline the results of research and development in the field of virtual reality. Virtual reality systems are based on the combination of a number of already existing presentation techniques like photo-realistic images, stereo images and real time animations. The added value of this type of CAD system is determined by the use of a new type of user interface. In effect this interface consists of sensors that register how its user moves and looks around. Through this, and by using a so- called 'eye phone' (comparable to stereo headphones for sound) the user, with some imaginative powers, thinks he is standing in the environment that he modelled, or in front of his building design. After this we will first sketch the outlines of some presentation techniques, that can also be found in a virtual reality system. Special attention will be paid to some specific characteristics of these techniques themselves. Next, a more detailed description will be given of virtual reality systems, focusing on the system that is being developed at Calibre itself.

summary Microcomputer techniques have been developed that combine CAD drawings with transportation network analysis software that uses spreadsheets and stand-alone programs activated from the DOS operating system. The CAD feature simplifies and improves the methods used to design pedestrian circulation facilities and evaluate the impact of new development on existing pedestrian flows. Through the use of customized software, the need for manual data entry is reduced, and the graphical display of analysis results in most intermediate steps in the process are automated. Three hypothetical case studies are presented, concentrating on proposed pedestrian circulation improvements at Penn Station, New York

title FULL-SCALE EXPERIMENT ON KITCHEN FUNCTION IN HANOI
source Proceedings of the 4rd European Full-Scale Modelling Conference / Lausanne (Switzerland) 9-12 September 1992, Part A, pp. 19-30
summary This study is a part of a licentiate thesis on "Functional kitchen for the Vietnamese cooking way"at the Department of Architecture and Development studies, Lund University. The issues it is dealing with are: (1) Inadequacy of kitchen design in the apartment buildings in Hanoi, where the kitchen is often designed as a mere cooking place - other parts of the food making process are not given any attention. (2) Lack of standard dimensional and planning criteria for functional kitchen which can serve as bases for kitchen design. // The thesis aims at finding out indicators on functional spatial requirements for kitchen, which can serve as guide-line for designing functional kitchen for Hanoi. One of the main propositions in the thesis is that functional kitchens for Hanoi should be organised to permit the culinary activities done according to the Vietnamese urban culinary practice. This is based on the concept that the culinary activity is an expression Of culture, thus the practice of preparing meal in the present context of the urban households in Hanoi has an established pattern, method which demand a suitable area and arrangement in the kitchen. This pattern and cooking method should make up the functional requirement for kitchen in Hanoi, and be taken in to account if functional kitchen designing is to be achieved. In the context of the space-limited apartment building of Hanoi, special focus is given to find out indicators on the minimum functional spatial requirements of the kitchen works.

title INTELLIGENT KNOWLEDGE-BASED REPOSITORY TO SUPPORT INFORMED DESIGN DECISION MAKING
source ITCON journal
summary Research highlights that architectural design is a social phenomenon that is underpinned by critical analysis of design precedents and the social interaction between designers including negotiation, collaboration and communication. CAAD systems are continuously developing as essential design tools in formulating and developing ideas. Researchers such as (Rosenman, Gero and Oxman 1992) have suggested suggest that knowledge based systems can be integrated with CAAD systems to provide design knowledge that would enable recalling design precedents that maybe linked to the design constraints. Currently CAAD systems are user centric being focused on architects rather than the end product. The systems provide limited assistance in the production of innovative design. Furthermore, the attention of the designers of knowledge based systems is providing a repository rather than a system that is capable to initiate innovation. Most of the CAAD systems have web communication tools that enable designers to communicate their design ideas with colleagues and partners in business. However, none of these systems have the capability to capture useful knowledge from the design negotiations. Students of the third to fifth year at College of Architecture, University of Dammam were surveyed and interviewed to find out how far design tools, communications and resources would impact the production of innovative design projects. The survey results show that knowledge extracted from design negotiations would impact the innovative design outcome. It highlights also that present design precedents are not very helpful and design negotiations between students, tutors and other students are not documented thus fully incorporated into the design scheme. The paper argues that the future CAAD systems should be capable to recognize innovative design precedents, and incorporate knowledge that is resulted from design negotiations. This would help students to gain a critical mass of knowledge that would underpin informed design decisions.

title Models and Hypermedia for Architectural Education

summary Hypermedia uses the hypertext style of interactive navigation through computer-based multimedia materials to provide access to a wealth of information for use by teachers and students. Academic disciplines concerned about the enlightenment of future designers of the built environment require an additional medium not yet available in hypermedia - interactive 3-D computer models. This paper discusses a hypermedia CAI system currently being developed at the University of Hong Kong for use in architectural education. The system uses interactive 3D computer models as another medium for instructional information, and as user orientation and database access devices. An object oriented, 3-D model hierarchy is used as the organizational structure for the database. A prototype which uses the system to teach undergraduate architecture students about a traditional Chinese temple is also illustrated. The prototype demonstrates the use of a computer as the medium for bilingual English and Chinese instruction.

summary Delft University of Technology, founded in 1842, is the oldest and largest technical university in the Netherlands. It provides education for more than 13,000 students in fifteen main subject areas. The Faculty of Architecture, Housing, Urban Design and Planning is one of the largest faculties of the DUT with some 2000 students and over 500 staff members. The course of study takes four academic years: a first year (Propaedeuse) and a further three years (Doctoraal) leading to the "ingenieur" qualification. The basic course material is delivered in the first two years and is taken by all students. The third and fourth years consist of a smaller number of compulsory subjects in each of the department's specialist areas together with a wide range of option choices. The five main subject areas the students may choose from for their specialisation are Architecture, Building and Project Management, Building Technology, Urban Design and Planning, and Housing.

The curriculum of the Faculty has been radically revised over the last two years and is now based on the concept of "Problem-Based Learning". The subject matter taught is divided thematically into specific issues that are taught in six week blocks. The vehicles for these blocks are specially selected and adapted case studies prepared by teams of staff members. These provide a focus for integrating specialist subjects around a studio based design theme. In the case of second year this studio is largely computer-based: many drawings are produced by computer and several specially written computer applications are used in association with the specialist inputs.

This paper describes the "block structure" used in second year, giving examples of the special computer programs used, but also raises a number of broader educational issues. Introduction of the block system arose as a method of curriculum integration in response to difficulties emerging from the independent functioning of strong discipline areas in the traditional work groups. The need for a greater level of selfdirected learning was recognised as opposed to the "passive information model" of student learning in which the students are seen as empty vessels to be filled with knowledge - which they are then usually unable to apply in design related contexts in the studio. Furthermore, the value of electives had been questioned: whilst enabling some diversity of choice, they may also be seen as diverting attention and resources from the real problems of teaching architecture.

summary The building industry involves a larger number of disciplines, operators and professionals than other industrial processes. Its peculiarity is that the products (building objects) have a number of parts (building elements) that does not differ much from the number of classes into which building objects can be conceptually subdivided. Another important characteristic is that the building industry produces unique products (de Vries and van Zutphen, 1992). This is not an isolated situation but indeed one that is spreading also in other industrial fields. For example, production niches have proved successful in the automotive and computer industries (Carrara, Fioravanti, & Novembri, 1989). Building design is a complex multi-disciplinary process, which demands a high degree of co-ordination and co-operation among separate teams, each having its own specific knowledge and its own set of specific design tools. Establishing an environment for design tool integration is a prerequisite for network-based distributed work. It was attempted to solve the problem of efficient, user-friendly, and fast information exchange among operators by treating it simply as an exchange of data. But the failure of IGES, CGM, PHIGS confirms that data have different meanings and importance in different contexts. The STandard for Exchange of Product data, ISO 10303 Part 106 BCCM, relating to AEC field (Wix, 1997), seems to be too complex to be applied to professional studios. Moreover its structure is too deep and the conceptual classifications based on it do not allow multi-inheritance (Ekholm, 1996). From now on we shall adopt the BCCM semantic that defines the actor as "a functional participant in building construction"; and we shall define designer as "every member of the class formed by designers" (architects, engineers, town-planners, construction managers, etc.).

summary Rapid developments in societal, technological, and natural systems suggest profound changes ahead if research in panarchical systems (Holling, 2001) is to be believed. Panarchy suggests that systems, both natural and man-made, rise to the point of vulnerability then fail due to disruptive forces in a process of ‘creative destruction.’ This sequence allows for radical, and often unpredictable, renewal. Pressing sustainability concerns, burgeoning urban growth, and emergent ‘green manufacturing’ laws, suggest that future urban dwellings are headed toward Gladwell’s ‘tipping point’ (2002). Hyper-dense, sustainable, urban communities that employ open-source standards, parametric software, and web-based configurators are the new frontier for venerable visions. Open-source standards will permit the design, manufacture, and sale of highly diverse, inter-operable components to create compact urban living environments that are technologically sophisticated, sustainable, and mobile. These mass-customised dwellings, akin to branded consumer goods, will address previous shortcomings for prefabricated, mobile dwellings by stimulating consumer desire in ways that extend the arguments of both Joseph Pine (1992) and Anna Klingman (2007). Arguments presented by authors Makimoto and Manners (1997) – which assert that the adoption of digital and mobile technologies will create large-scale societal shifts – will be extended with several solutions proposed.

title Systems Thinking, Systems Practice

summary Whether by design, accident or merely synchronicity, Checkland appears to have developed a habit of writing seminal publications near the start of each decade which establish the basis and framework for systems methodology research for that decade."" Hamish Rennie, Journal of the Operational Research Society, 1992 Thirty years ago Peter Checkland set out to test whether the Systems Engineering (SE) approach, highly successful in technical problems, could be used by managers coping with the unfolding complexities of organizational life. The straightforward transfer of SE to the broader situations of management was not possible, but by insisting on a combination of systems thinking strongly linked to real-world practice Checkland and his collaborators developed an alternative approach - Soft Systems Methodology (SSM) - which enables managers of all kinds and at any level to deal with the subtleties and confusions of the situations they face. This work established the now accepted distinction between hard systems thinking, in which parts of the world are taken to be systems which can be engineered, and soft systems thinking in which the focus is on making sure the process of inquiry into real-world complexity is itself a system for learning. Systems Thinking, Systems Practice (1981) and Soft Systems Methodology in Action (1990) together with an earlier paper Towards a Systems-based Methodology for Real-World Problem Solving (1972) have long been recognized as classics in the field. Now Peter Checkland has looked back over the three decades of SSM development, brought the account of it up to date, and reflected on the whole evolutionary process which has produced a mature SSM. SSM: A 30-Year Retrospective, here included with Systems Thinking, Systems Practice closes a chapter on what is undoubtedly the most significant single research programme on the use of systems ideas in problem solving. Now retired from full-time university work, Peter Checkland continues his research as a Leverhulme Emeritus Fellow. "

summary Modelling knowledge and data in CAD/CAM applications is complex because different goals and contexts have to be taken into account. This complexity makes particular demands upon representation formalisms. Today many modelling tools are based on record structures. By analyzing the requirements for a product model of a portal structure in steel, this paper shows that in many situations record structures are not well suited as a representation formalism for storing knowledge and data in CAD/CAM applications. This is illustrated by performing a knowledge-level analysis of the knowledge and data generated in the design and manufacturing process of a portal structure in steel.

summary In this paper we present a strategy for modeling urban development in order to study the role of urban regulations and policies in the transformation of cities. We also suggest a methodology for using computer models as experimental tools in the urban design studio in order to make explicit the factors involved in shaping cities, and for the automatic visualization of projected development. The structure of the proposed model is based on different modules which represent, on the one hand, the rules regulating the physical growth of a city and, on the other hand, heuristics corresponding to different interests such as Real Estate Developers, City Hall Planners, Advocacy and Community Groups, and so on. Here we present a case study dealing with the Boston Redevelopment Authority zoning code for the Midtown Cultural District of Boston. We introduce a computer program which develops the district, adopting a particular point of view regarding urban regulation. We then generalize the notion of this type of computer modeling and simulation, and draw some conclusions about its possible uses in the teaching and practice of design.

summary The research we will discuss below originated from an attempt to examine the capacity of designers to evaluate an artifact, and to study the feasibility of replicating a designer's moves intended to make an artifact more expressive of a given quality. We will present the results of an interactive computer experiment, first developed at the MIT Design Research Seminar, which is meant to capture the subject’s actions in a simple design task as a series of successive "moves"'. We will propose that designers use metaphors in their interaction with design artifacts and we will argue that the concept of metaphors can lead to a powerful theory of design activity. Finally, we will show how such a theory can drive the project of building a design system.

When trying to understand how designers work, it is tempting to examine design products in order to come up with the principles or norms behind them. The problem with such an approach is that it may lead to a purely syntactical analysis of design artifacts, failing to capture the knowledge of the designer in an explicit way, and ignoring the interaction between the designer and the evolving design. We will present a theory about design activity based on the observation that knowledge is brought into play during a design task by a process of interpretation of the design document. By treating an evolving design in terms of the meanings and rules proper to a given way of seeing, a designer can reduce the complexity of a task by focusing on certain of its aspects, and can manipulate abstract elements in a meaningful way.

summary The building envelope design process involves selecting materials and constructional types for envelope components. Many different materials need to be combined together for wall and roof assemblies to meet the various performance requirements such as thermal efficiency, cost, acoustic and fire resistances. The number of performance attributes to be considered in the design process is large. Lack of information, time limitations and the large number of feasible design alternatives generally force the designer to rely on past experience and practical judgement to make rapid design decisions. Current work at the Centre for Buildings Studies focuses on the development of knowledge-based synthesis and evaluation techniques for reducing the problems of information handling and decision making in building envelope design. The generation of design alternatives is viewed as a search process that identifies feasible combinations of building envelope components satisfying a set of performance requirements, material compatibility, practicality of design, etc. This paper discusses knowledge acquisition and representation issues involved in the definition of constraints to guide the generation of feasible combinations of envelope components

title Performance Evaluation in an Integrated Software Environment for Building Design and Construction Planning
source New York: John Wiley & Sons, 1992. pp. 159-169 : ill. includes bibliography
summary In this paper the authors describe the role of performance evaluation in the Integrated Software Environment for Building Design and Construction Planning (IBDE), which is a testbed for examining integration issues in the same domain. Various processes in IBDE deal with the spatial configuration, structural design, and construction planning of high-rise office buildings. Performance evaluations occur within these processes based on different representation schemes and control mechanisms for the handling of performance knowledge. Within this multiprocess environment, opportunities also exist for performance evaluation across disciplines through design critics

title Topological Design of Sculptured Surfaces
source Computer Graphics, no. 26, pp.149-156
summary Topology is primal geometry. Our design philosophy embodies this principle. We report on a new surface &sign perspective based on a "marked" polygon for each object. The marked polygon captures the topology of the object surface. We construct multiply periodic mappings from polygon to sculptured surface. The mappings arise naturally from the topology and other design considerations. Hence we give a single domain global parameteriration for surfaces with handles. Examples demonstrate the design of sculptured objects and their ntanufimture.
