title	Tool profile and tool path calculation for free-form thick-layered fabrication
source	Computer-Aided Design, Vol. 30 (14) (1998) pp. 1097-1110
summary	In several application fields, large sized, free-form objects of various soft materials are widely used. Available layered prototyping technologies cannot be applied forfabrication of these kinds of objects due to size limitations. The authors have developed a novel approach of layered manufacturing that is the most appropriate forphysical concept modeling. This paper presents the algorithms for geometrically-based modeling of the profile curve of the flexible blade tool. It also describes thealgorithm for direct slicing of the CAD model. The second part of the paper deals with the algorithms for slicing, tool positioning and tool path calculation. On thefront surfaces of the layers G2, quasi G1 continuity can be implemented at the transition from one layer to another. In the circumferential direction G0 continuityexists.

title	Computational intelligence: soft computing and fuzzy-neuro integration with applications
source	Springer, Berlin
summary	Soft computing is a consortium of computing methodologies that provide a foundation for the conception, design, and deployment of intelligent systems and aims to formalize the human ability to make rational decisions in an environment of uncertainty and imprecision. This book is based on a NATO Advanced Study Institute held in 1996 on soft computing and its applications. The distinguished contributors consider the principal constituents of soft computing, namely fuzzy logic, neurocomputing, genetic computing, and probabilistic reasoning, the relations between them, and their fusion in industrial applications. Two areas emphasized in the book are how to achieve a synergistic combination of the main constituents of soft computing and how the combination can be used to achieve a high Machine Intelligence Quotient.

title	Consequences of Interdisciplinary Approaches in the Construction ofKnowledge-Bases
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The character of interdisciplinarity in planning approaches create a new, intriguing, emerging complexity (Funtowitcz and Ravetz, 1994) in problems and in knowledge-structuring of contexts of planning practices. The key-role played by information systems (IS) implicates a re-consideration ofcharacter of knowledge to be used in knowledge-bases. The necessity of considering knowledge domains coming from social, cultural, economical, technical, physical and naturalistic approaches means dealing with different scales of value, with non homogenous parameters. The necessity ofmanaging flexible knowledge rises on the fore as fundamental issue for future information system oriented to supporting decisions. Might information systems be useful in this interdisciplinary approach ? It is necessary to contain in a knowledge-base both quantitative and qualitativeinformation ? Three alternatives are available for a conceptual discussion :the possibility of identify new approaches, in order to develop information systems able in managing new knowledge; the necessity of adding new support systems oriented to manage soft knowledge, to traditionalgeographic information systems (GIS); the possibility of non using support systems coming from a technological vision of problem for nontechnical knowledge (Latouche 1996). The first two paragraphs are due to F. Selicato. The third and the fourth paragraph are due to C. Torre.

summary	It seems that when architects think, and talk about computers, they only reflect on very narrow images of the phenomenon. Architects think that the impact of computers in their profession is only related to how PCs, CAD/CAM, networks, software, peripherals, can improve the way they work today. Architects, by enlarge, are unable to reflect beyond the screen of their computers and the wall of their offices when it comes to recognize the real consequences resulting from the new technological advances. In this paper we argue that we should think differently. We must recognize that computers are having much more profound impact on the profession. Computers - the technology of the fantastic, par excellence - are changing the city! They are fundamentally transforming the way we use space, and buildings! Computers are beginning to create new kinds of urban cultures and infrastructures. Building types such as offices, banks, retail spaces, and museums are being transformed into virtual workplaces, telecommuting centers, networks of automated teller machines, home banking, smart stores and multimedia experiences. Computers are transforming the concept of working, the concept of banking, the concept of shopping, etc. In the end, something fundamental about the architecture of these activities.

title	Extending spatial DSS with spatial choice models of multipurpose shopping trip behaviour
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Spatial choice or interaction models have been widely used in spatial DSS or customised GIS for analysing the impacts of retail location plans. The models typically used, however, do not account for spatial agglomeration effects on spatial choice behaviour. This study develops a model system for analysing the impacts of retail plans based on a choice model of multipurpose behaviour developed in earlier work. The model system is implemented in the spatial DSS called Location Planner. An empirical study demonstrates the empirical estimation and use of the model for analysing the impacts of an expansion of floor space in the major shopping centre of a middle-sized city in The Netherlands. The results indicate that agglomeration effects as predicted by the model can have substantial impacts on the performance of retail systems. Therefore, it is argued that when incorporated in a spatial DSS, the more complex models have the potential to improve the use of these systems for impact analysis.

title	Changing trends and approaches in human and computer modelling for social housing policies
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The paper discusses conceptual issues, goals and preliminary results of an on-going research which aims at building a Decision Support System for public housing environmental oriented maintenance and management in a city in Southern Italy, Bari. Traditional post-war Italian housing policies are compared with more recent approaches in the field, pointing out the change from quantitative, aggregated, more simple building problems and relatedapproaches to qualitative, differentiated, complex ones integrating social, economic and environmental dimensions with the aim of regenerating deteriorated residential areas. The paper claims for the need shift, both in the human and computer areas, from traditional quantitative models to new approaches able to manage also qualitative variables, temporal dynamics, emergencies, and intentionality, since they appear key aspects of the real world to be modelled. The housing estate of Bari and its needs of maintenance and management are examined, eliciting essential related knowledge using the interview technique. The clear orientation towards sustainable policies for urban regeneration, at a local, national, and Community level, is also considered. The innovative and collaborative nature of such policies and the attention to be paid to the social aspects ofthe problem require a complex DSS, integrating various kind of hypertexts, information systems and case-based fuzzy expert systems, whose main aims, functions, software and general organisation are outlined in the paper.

title	Virtual Tour Through Modern Architecture in Conception
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 475-477
summary	This paper describes the development of a project that was selected and sponsoured by the Regional Competition FONDART 1998 (Funds for the Development of Arts of the Regional Secretary of Education) that follows the aim of cultural diffusion. Towards the middle of the 30s, the city of Concepción developed an architecture distinctly colonial, neoclassical and eclectic. An earthquake in 1939 abruptly interrupted this scene, destroying the enterity of its most important buildings. The reconstruction of the city followed the manifestoes of Modern Architecture, consolidating the urban importance of buildings such us the Law Courts, the Railway Station and the Regional Government, that emerged as the new architectural and cultural heritage of the city. The project consisted on the modeling of eleven buildings of the modern architectural heritage, and on the generation of 42 virtual tours through the buildings that were finally edited on a 16' video. This video allows the spectator to make a virtual tour through the original modern heritage of the city, nowadays demolished, altered, and sometimes, even forgotten. This project pretends to widen the ways of comprehension of our cultural identity by using computer modelling and animation as a tool for the conservation of the architectural heritage; and creating a record that can be used as a reference and as an instrument of cultural difussion.

title	Media Interaction & Design Process: Establishing a Knowledge Base
doi	https://doi.org/10.52842/conf.acadia.1998.006
source	Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 6-25
summary	Integrating computers in architectural design means to negotiate between centuries-old analog design methods and the new digital systems of production. Analog systems of architectural production use tracing paper, vellum, graphite and ink, clipboard, clay, balsa wood, plastic, metal, etc. Analog systems have also been termed ‘handmade’, ‘manual’, ‘material’ or ‘physical’. Digital systems of architectural production use scanning, image manipulation, visualization, solid modeling, computer aided drafting, animation, rendering, etc. Digital systems have also been called ‘electronic’, ‘computer-aided’, ‘virtual’, etc. The difficulty lies in the underdeveloped state of the necessary methods, techniques, and theories to relate traditional and new media. Recent investigations on the use of multiple iterations between manual and electronic systems to advance architectural work show promising results. However, these experiments have not been sufficiently codified, cross-referenced and third party tested to conform a reliable knowledge base. This paper addresses this shortcoming by bringing together reported experiences from diverse researchers over the past decade. This summary is informed by more than three years of continuous investigation in the impacts of analog-digital conversations in the design process. The goal is to establish a state-of-the-art common foundation that permits instructors, researchers and practitioners to refer to, utilize, test, criticize and develop. An appendix is included providing support for the paper’s arguments.

title	Balancing Computer Use and Design Content in Studio Projects
doi	https://doi.org/10.52842/conf.acadia.1998.036
source	Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 36-43
summary	Particular design approaches must be taught in order to take advantage of the strengths of computers in design rather than attempting to make computers conform to methods developed as by-products of manual design techniques. For the last three years our team of faculty teaching the second year design studio has been trying different approaches to the use of computers in design, in order to find the advantages and opportunities especially suited to electronic media. There are several projects during the semester which use computers at different stages of the design process. One of these projects, called “A Spatial Sequence,” uses information from a previous project as well as the knowledge from the computer class in parallel to design studio. The project asked students to create spatial archetypes based on the work of well-known architects. They explore the following topics as represented in the work of one particular architect: relationships of major spaces/minor spaces, approach/entry, and transition/threshold. Following the analysis, they create digital models to explore the spaces formed by their archetypes. Before committing to a physical study model, they look at the transitions between spaces by creating a sequence using the digital model and producing a series of shots through the digital model to show the flow of spaces. The use of computer through the process accelerates the options available to explore a sequence of elements, while simultaneously giving them a window to look into the spaces they have created. This hybridized approach of precedent analysis, digital modeling, and physical modeling was uniquely suited to the studio problem.

summary	The idea of making a Data Base of Resistencia City, came through the evaluation of the potential educational, touristic and commercial value that this sort of information has. The fragmented state of the information and its nonsystematic registration up to now emphasize the real value of this project. The different subjects are grouped in the following headings: Sculpture, Architecture, Places and Cultural Events. They are presented to the user as multimedia data in CD. The information available could be printed.

title	A comparison of land valuation methods supported by GIS
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The purpose of this work was to study three different strategies for the appraisal of urban land. The first, a theoretical strategy created by the authors of this study to reproduce the common conditions of Brazilian cities, uses increments and reductions in the value of a square meter of land according to each lot’s individual features. The second method, based on Multiple Regression techniques, is widely used for valuation purposes. Finally, the effectiveness of Artificial Neural Networks to deal with thiskind of problem is studied. A sample of 157 lots was collected from several neighbourhoods of a small Brazilian city for the case study. The lot features recorded were area, width, shape, distance to the downtown district of the city through the street network, existence of fences and paved sidewalks, and market price. Prediction errors have been estimated for each of the three methods in order to compare their results. Predicted and error values, added to Geographical Information Systems, may be used to build thematic maps and to check how each strategy applies to different areas of the city. The analyses of error values conducted in this study showed that Artificial Neural Networks presented the best performance as a land appraisal method for the case studied.

summary	The Virtual Reality Modeling Language (VRML) and the World Wide Web (WWW) offer new opportunities to communicate an architect’s design intent throughout the design process. We have investigated the use of VRML in the production and communication of construction documents, the final phase of architectural building design. A prototype, experimental Web site was set up and used to disseminate design data as VRML models and HTML text to the design client, contractor, and fabricators. In this paper, we discuss the way our construction documents were developed in VRML, the issues we faced implementing it, and critical feedback from the users of the Web space/site. We analyze the usefulness of VRML as a communication tool for the design and construction industries. Finally, we discuss technical, social, and legal issues the AEC industry faces as it shifts to embrace widespread use of a “paperless” Web-based communications infrastructure for design documentation.

title	Cultivating Design Competence: Online Support for the Beginning Design Studio
doi	https://doi.org/10.52842/conf.acadia.1998.290
source	Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 290-299
summary	A primary lesson of a beginning design studio is the development of a fundamental design competence. This entails acquiring skills of integration, projection, exploration, as well as critical thinking–forming the basis of thinking “like a designer.” Plaguing the beginning architectural design student as she develops this competence are three typical problems: a lagging visual intelligence, a linking of originality with creativity, and the belief that design is an act of an individual author instead of a collaborative activity. We believe that computation support for design learning has particular attributes for helping students overcome these problems. These attributes include its inherent qualities for visualization, for explicitness, and for sharing. This paper describes five interactive multi-media exercises exploiting these attributes which were developed to support a beginning design studio. The paper also reports how they have been integrated into the course curriculum.

summary	This paper depicts the use of computers in the urban studies, and provides a digital way of understanding historical buildings. "Discovery of Historical Tainan" is a joint project among historians and CAD researchers to use a digital approach to preserve historical evidences of the central city of Tainan. The importance of historical scenes is revealed by the efforts of integration with digital information and models. Furthermore, the level of abstraction and accuracy in the large-scale urban models are examined. The result demonstrates that the ability of foreseeing the future changes can be enhanced by the digital approach.

title	Delivering Facility Documentation using Intranet Technology
doi	https://doi.org/10.52842/conf.acadia.1998.240
source	Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 240-253
summary	Intranet technologies present new opportunities for delivering facility documentation for use in facility management. After the design stage, building documentation is reused to support construction and then facility operation. However, a common perception is that construction documents and as-built drawings are less than optimal for reuse to support operations. We have conducted a study of facility management processes and the information content of facility documentation in the context of information technologies that are emerging into the marketplace. The study provides guidance for facility managers who are implementing and fielding new information technology systems. A better understanding of information needs during operations may also help designers to better structure their own documents for reuse. An analysis of documents that are used throughout the life cycle of facilities has led us to a characterization of operations documents that are distinct from design drawings, record drawings or as-built drawings. From an analysis of facility management processes, we have identified different roles for facility documentation in those processes. Facility documentation may be used as a resource, as input, or as output. Furthermore, from interviews of facility management personnel, we identified facility information that was rated high in importance and low in satisfaction that might be targeted when implementing a facility information system. We prepared software demonstrations that show how the information may be extracted from drawings, entered into databases and then retrieved via Web and CAD interfaces. We suggest that operations documents consist of a variety of information types and require several kinds of information tools, including databases, CAD drawings and hypertext. Intranet technologies, databases and CAD software can be integrated to achieve facility management systems that address shortcomings in current facility management operations. In particular, intranet technologies provide improved accessibility to information for facility management customers and occasional users of the systems. Our study has produced recommendations based upon utility and ease-of-implementation for delivery of information from the design team to the owner, and among personnel during operation of the facility.
