title	Exploring the Development of the Independent, Electronic, Scholarly Journal
source	University of Sheffield, Department of Information Studies
summary	This dissertation sets out to examine the extent of independent, electronic scholarly journals, that is, those that are available through the Internet, usually the World Wide Web, free of charge to the reader, and publish academic articles, usually peer reviewed. A list of journals was drawn up using the NewJour archive of journal announcements, supplemented by the World Wide Web Virtual Library and Glasgow University library catalogue. The 387 journals that were found were then categorised in the following categories: Title, URL, originating country, whether it was peer reviewed, organisation or person responsible, broad subject, narrow subject, format, language, whether there was a print version, year of first issue, year of latest issue and number of issues and articles per year. An e-mail survey was also carried out of the 84 electronic journals that had some way of determining their readership, either by having voluntary or compulsory registration, or sending e-mail updates to subscribers. The survey asked for the number of subscribers to each journal, and also the number of hits the Web site received each month It was found that most of the journals were following one of three strategies: () a Niche Market strategy - focusing a highly specialised journal to a small audience. () a Vanity Publishing strategy - producing journals in a mainstream area, with no external funding.(*) a Commercial strategy - producing journals in a mainstream area, with attempts made to gain external funding through sponsorship and advertising. It was concluded that unless the current market for electronic journals changed in some way, either by journal budgets devolving to academic departments, or some collaborative action between universities, that the future for electronic journals was as part of "one-stop shops" for particular subjects, with a mixture of free and paid for journals (or article servers), together with other related services, controlled by commercial outfits.

title	Decoding to 2000 CAD as Mediator

summary	This paper will present examples of current practice in the Design Studio course of the BDE, University of Strathclyde. The paper will demonstrate an integrated approach to teaching design, which includes CAD among other visual communication techniques as a means to exploring design concepts and the presentation of complex information as part of the design process. It will indicate how the theoretical dimension is used to direct the student in their areas of independent study. Projects illustrated will include design precedents that have involved students in the review and assessment of landmarks in the history of design. There will be evidence of how students integrate DTP in the presentation of site analysis, research of appropriate design precedents and presentation of their design solutions. CADET underlines the importance of considering design solutions within the context of both our European cultural context and of assessing the environmental impact of design options, for which CAD is eminently suited. As much as a critical method is essential to the development of the design process, a historical perspective and an appreciation of the sophistication of communicative media will inform the analysis of structural form and meaning in a modem urban context. Conscious of the dynamic of social and historical influences in design practice, the student is enabled "to take a critical stand against the dogmatism of the school "(Gadamer, 1988) that inevitably insinuates itself in learning institutions and professional practice.

title	Product modeling standards for the building and construction industry: past, present and future
source	Automation in Construction 8 (3) (1999) pp. 227-235
summary	For the past ten years most sectors of industry have been developing standards for the electronic sharing and exchange of product model data. While several related industries, such as automotive and shipbuilding manufacturing have been relatively successful in integrating electronic product models into their operations, the building and construction industry, continues to lag behind in this development. In order for the building and construction industry to meet the challenges of the future, the development of a product modeling standard that enables sharing, storing and exchanging project information electronically is essential. The paper discusses the rationale behind this assertion and includes a discussion of the industry requirements for the development of a product modeling standard. The paper elaborates on the results of the standardization efforts of the past and present, followed by an analysis of the current development situation. Finally, personal views are expressed regarding future development in the area of information exchange.

summary	In 1998, thanks to the support of the Program to Enhance Scholarly and Creative Activities of Texas A&M University, the author was able to establish a digital research network that promotes and coordinates collaborative research and development projects at inter-continental level. The original objective was to establish a network of 5 schools of Architecture. This objective was largely surpassed. At the time of editing this paper, the Las Américas Digital Research Network brings together 17 schools of Architecture (from Canada to Argentina). See http://taz.tamu.edu/~americas/ In this collaborative framework, we have been able to identify a number of research and development opportunities. This paper reports on some of the on-going initiatives of the network, namely: a) The Las Americas Virtual Design Studio, b) The Las Americas Virtual Gallery of Visual Arts, c) The Las Americas Research Journal "Archi-Forum" and, d) The Las Americas Curriculum Harmonization Initiative. In addition to a report on current activities, this paper aims to promote new initiatives and identify potential sources of research & development funding. The paper ends with conclusions and a call for widespread participation.

title	Standards media and methods
source	Automation in Construction 8 (4) (1999) pp. 473-479
summary	The global marketplace and advances in information technologies are leading to great changes in standards. These include growing reliance on international standards, new standards-development techniques, and new media and environments in which standards are expressed. Both general and project-specific information are being stored in and accessed from distributed, electronic, object-oriented databases. Standards available from general-purpose information systems will be capable of accessing and processing data to evaluate compliance with their provisions. Such standards will be convenient and efficient: input data will be accessed automatically from pertinent fields of the general and project-specific databases; results of evaluations will be recorded automatically in the project-specific database and used in decisions affecting design, construction or operation of constructed facilities. Major uses of standards will be associated with computer-aided systems and major revenues from uses of standards will accrue to systems developers and users. Standards-developing organizations should respond to this marketplace by themselves producing standards in the form of executable objects. Computer aids can assist in the formulation and expression of standards that are complete in coverage of the intended scope, consistent and unambiguous in their logic, and correct in reproducing the intent of the formulators.

title	Where the Footprints Lead: Tracking down other roles for social navigation
source	Social Navigation of Information Space, eds. A. Munro, K. H. and D Benyon. London: Springer-Verlag, pp 15-34
summary	Collaborative Filtering was proposed in the early 1990's as a means of managing access to large information spaces by capturing and exploiting aspects of the experiences of previous users of the same information. Social navigation is a more general form of this style of interaction, and with the widening scope of the Internet as an information provider, systems of this sort have rapidly moved from early research prototypes to deployed services in everyday use. On the other hand, to most of the HCI community, the term social navigation" is largely synonymous with "recommendation systems": systems that match your interests to those of others and, on that basis, provide recommendations about such things as music, books, articles and films that you might enjoy. The challenge for social navigation, as an area of research and development endeavour, is to move beyond this rather limited view of the role of social navigation; and to do this, we must try to take a broader view of both our remit and our opportunities. This chapter will revisit the original motivations, and chart something of the path that recent developments have taken. Based on reflections on the original concerns that motivated research into social navigation, it will explore some new avenues of research. In particular, it will focus on two. The first is social navigation within the framework of "awareness" provisions in collaborative systems generally; and the second is the relationship of social navigation systems to spatial models and the ideas of "space" and "place" in collaborative settings. By exploring these two ideas, two related goals can be achieved. The first is to draw attention to ways in which current research into social navigation can be made relevant to other areas of research endeavour; and the second is to re-motivate the idea of "social navigation" as a fundamental model for collaboration in information-seeking."

summary	Fake.space is an elective CAAD course in which teachers and students form an online community. It is a Web-based communication environment for the exchange of ideas on the concept of space. Fake.space is also a narrative structure consisting of threads of nodes created by students. These nodes present different aspects of space. Fake.space represents our current generation of teaching environments. In this paper we describe and analyse its latest incarnation and discuss our aims and thoughts for further development. We believe that fake.space reflects on a future where online environments entice the students in a playful way to work with computers and CAD and consider the role of networked environments in architectural space.

title	Digital Simulation and Inferential Systems
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 87-92
summary	From the perspective of logic and epistemological formalizations, the processes for data elaboration relate reasoning schemes to inferential operations which enable the building, understanding and setting of criteria for knowledge validation in a complex sequence. Cognitive operations do not belong exclusively to the field of discourse thinking,' they also apply to the field of perception. Specially in the area of images, there exist inferences which are expressed and operated through other media. A particular aspect is the one of digital simulation and the links established with inferential systems. Although they are not the same thing, since simulation is a cognitive methodology, both are based on similar logic principles. It is obviously necessary to build budget or referential frameworks to support practices deriving from the graphic/digital culture. Thus, they could act as judgement instruments in order to analyze and recognize changes in project, space, morphological and expressive paradigms, and to overcome the instrumental and reductionist bias usually found in the development of these practices. The present work is oriented in this direction, studying relations established among digital simulation, inferential systems, cognitive elaboration and scientific knowledge validation. We aim at exploring and researching into the affinity, links and differences between simulation and analogic-abductive inferential systems so as to characterize: 1.) The concept of digital simulation, not only due to its strong reproductive power but to its inherent referential, cognitive and poetic functions. 2.) The nature of replacing actions projected by simulation with respect to reality in order to produce a representative act the innovative and creative power of simulation, directed both to the past and the future. 3.) The dimensions of prevision and interpretation where simulation develops its theoretical and empirical attitudes and the idea that simulation derives from the combination of hypothesis and experimentation.

source	Automation in Construction 8 (3) (1999) pp. 277-289
summary	The development of a system capable of integrating a range of building design tools poses many challenges. Our framework for integrating design tools provides a structured approach, allowing individual parts to be developed independently. In this paper, we describe the overall framework and suggest a method for modeling and implementing each portion of the framework. Furthermore, we illustrate how such a system can integrate several design tools and be realized as a functional design system.

source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 276-289
doi	https://doi.org/10.52842/conf.acadia.1999.276
summary	This white-paper builds upon previous research to present hybrids of electronic and physical spaces as extensions of current design practice. It poses an hypothetical project - a hybrid of physical and cyberspaces - to be developed through an extrapolation of current architectural practice by fully exploiting new information technologies. The hybrid's attributes not only affect the scope of development but the very activities of the design team and client during - and after - deployment. The entire life cycle of the project is affected by its dual material and media presence. The paper concludes by discussing the effect the hybrid - here called a "cybrid" - on the occupant, and its local and global communities. It reviews the economics, administration, marketing, operation, flexibility, and extension of the project to assess its effects on these scales. The conclusions are provisional owing to the youth of the technologies. However, in laying out these issues, the author hopes to begin a discussion on effects computation will have on our built environment.

title	Research and development needs for better implementation of the performance concept in building
source	Automation in Construction 8 (4) (1999) pp. 525-532
summary	Gaps in basic knowledge, inadequacies in the procedural infrastructure and lack of working tools, that still prevent a more systematic application of the performance concept throughout the building process, are identified. One of the main conclusions is that, despite the vast knowledge accumulated during the years in the fields of ergonometrics, human needs, human factor engineering, architectural design, structural analysis, building physics, building materials and durability analysis, this knowledge is not applied systematically during the building process. The situation is attributed to lack of tools for some of the decision making phases in the process, and to the lack of a common, preferably computerized, design platform that would ensure a comprehensive and quantitative approach to all the relevant performance attributes, link smoothly between the various phases along the project development, and minimizes bias caused by human experts.

doi	https://doi.org/10.52842/conf.ecaade.1999.700
summary	Our paper presents recent developments of a co-operation program that links the MAP-GAMSAU CNRS laboratory (Marseilles, France), specialised in computer science and the HAiKZ Institute of Krakow's Faculty of Architecture, specialised in architectural heritage and conservation. Before undertaking any action to a listed building or interventions in its neighbourhood, it is vital to gain a clear understanding of the building in question. Numerous heterogeneous data detained by diverse institutions has to be handled. This process can be greatly eased by enhanced classification of the information. The development we present is a multidisciplinary platform independent information tool dedicated to education and research. SOL uses an http protocol centred computer architecture connecting a relational database, a VRML 2.0 representation module and a web search interface. It allows searches and updating of the database through a standard text based interface, a VRML 2.0 graphical module and a thematic interface. SOL is experienced on the urban fabric of the Main Square (Rynek Gówny) in Kraków. The choice of a web-centred development, both in the search and updating interface and in the representation module provides platform independence and distant access to the database, and enables successive contributions of students or researchers.

title	A database supporting evolutionary product model development for design
source	Automation in Construction 8 (3) (1999) pp. 305-323
summary	This paper presents the facilities in the EDM-2 product modeling and database language that support model evolution. It reviews the need for model evolution as a system and/or language requirement to support product modeling. Four types of model evolution are considered: (1) translation between distinct models, (2) deriving views from a central model, (3) modification of an existing model, and (4) model evolution based on writable views associated with each application. While the facilities described support all for types of evolution, the last type is emphasized. The language based modeling capabilities described in EDM-2 include: (a) mapping facilities for defining derivations and views within a single model or between different models; (b) procedural language capabilities supporting model addition, deletion and modification; (c) support for object instance migration so as to partition the set of class instances into multiple classes; (d) support for managing practical deletion of portions of a model; (e) explicit specification and automatic management of integrity between a building model and various views. The rationale and language features, and in some cases, the implementation strategy for the features, are presented.

source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary	Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title	Modeling of energy demands for residential buildings with HTML interface
source	Automation in Construction 8 (4) (1999) pp. 481-487
summary	This paper presents the package for calculation of energy and cost demands for heating, cooling and hot water. The package represents a new kind of approach to developing software, employing user (client) and server (program provider) computers connected by Internet. It is mounted on the owner server and is available to the whole world through the Web browser. The package was developed as a simplified tool for estimating energy use in four types of new and old houses, located in 900 US cities. The computing engine utilizes the database that was compiled by LBL in support of the 'Affordable Housing through Energy Conservation' Project with over 10000 DOE-2.1 simulations. The package consists of 69 routines and scripts coded in four languages: HTML, Perl, C, and FORTRAN. The modeling, the programming, and the future perspectives of the new kind of computational tool are presented. The paper discusses further technical limitations, as well as suggestions for further improvements and development. Especially important is the problem of multi-user access; ways for its solution are proposed.

summary	This paper describes an ongoing effort focused on combined research and curriculum development for multidisciplinary, geographically distributed architecture/engineering/construction (A/E/C) teamwork. Itpresents a model for a distributed A/E/C learning environment and an Internet-based Web-mediated collaboration tool kit. The distributed learning environment includes six universities from Europe, Japan, andthe United States. The tool kit is aimed to assist team members and owners (1) capture and share knowledge and information related to a specific project; (2) navigate through the archived knowledge andinformation; and (3) evaluate and explain the product's performance. The A/E/C course offered at Stanford University acts as a testbed for cutting-edge information technologies and a forum to teach newgenerations of professionals how to team up with practitioners from other disciplines and take advantage of information technology to produce a better, faster, more economical product. The paper presents newassessment metrics to monitor students' cross-disciplinary learning experience and track programmatic changes. The paper concludes with challenges and quandaries regarding the impact of informationtechnologies on team performance and behavior.

source	C. Freksa and D. Marks (eds), Spatial Information Theory, Springer, Berlin, pp. 315-330
summary	This paper describes some recent cognitively-based and computationally- based research on representing and reasoning about shapes. The cognitive studies are based on protocol analyses of designers and indicate that visual reasoning in design involves drawings of shapes and their relations in the generation of unexpected results. The computational studies are concerned with the development of qualitative representations of shapes that can be used to reason about shapes. Two representations are described: half-planes and landmark-based qualitative codes. Reasoning using these representations is presented.

title	Hyposurface: from Autoplastic to Alloplastic Space
source	International Conference on Generative Art
summary	By way of immediate qualification to an essay which attempts to orient current technical developments in relation to a series of dECOi projects, I would suggest that the greatest liberation offered by new technology in architecture is not its formal potential as much as the patterns of creativity and practice it engenders. For increasingly in the projects presented here dECOi operates as an extended network of technical expertise: Mark Burry and his research team at Deakin University in Australia as architects and parametric/ programmatic designers; Peter Wood in New Zealand as programmer; Alex Scott in London as mathematician; Chris Glasow in London as systems engineer; and the engineers (structural/services) of David Glover’s team at Ove Arup in London. This reflects how we’re working in a new technical environment - a new form of practice, in a sense - a loose and light network which deploys highly specialist technical skill to suit a particular project. By way of a second disclaimer, I would suggest that the rapid technological development we're witnessing, which we struggle to comprehend given the sheer pace of change that overwhelms us, is somehow of a different order than previous technological revolutions. For the shift from an industrial society to a society of mass communication, which is the essential transformation taking place in the present, seems to be a subliminal and almost inexpressive technological transition - is formless, in a sense - which begs the question of how it may be expressed in form. If one holds that architecture is somehow the crystallization of cultural change in concrete form, one suspects that in the present there is no simple physical equivalent for the burst of communication technologies that colour contemporary life. But I think that one might effectively raise a series of questions apropos technology by briefly looking at 3 or 4 of our current projects, and which suggest a range of possibilities fostered by new technology. By way of a third doubt, we might qualify in advance the apparent optimism of architects for CAD technology by thinking back to Thomas More and his island ‘Utopia’, which marks in some way the advent of Modern rationalism. This was, if not quite a technological utopia, certainly a metaphysical one, More’s vision typically deductive, prognostic, causal. But which by the time of Francis Bacon’s New Atlantis is a technological utopia availing itself of all the possibilities put at humanity’s disposal by the known machines of the time. There’s a sort of implicit sanction within these two accounts which lies in their nature as reality optimized by rational DESIGN as if the very ethos of design were sponsored by Modern rationalist thought and its utopian leanings. The faintly euphoric ‘technological’ discourse of architecture at present - a sort of Neue Bauhaus - then seems curiously misplaced historically given the 20th century’s general anti-, dis-, or counter-utopian discourse. But even this seems to have finally run its course, dissolving into the electronic heterotopia of the present with its diverse opportunities of irony and distortion (as it’s been said) as a liberating potential.1 This would seem to mark the dissolution of design ethos into non-causal process(ing), which begs the question of ‘design’ itself: who 'designs' anymore? Or rather, has 'design' not become uncoupled from its rational, deterministic, tradition? The utopianism that attatches to technological discourse in the present seems blind to the counter-finality of technology's own accomplishments - that transparency has, as it were, by its own more and more perfect fulfillment, failed by its own success. For what we seem to have inherited is not the warped utopia depicted in countless visions of a singular and tyrranical technology (such as that in Orwell's 1984), but a rich and diverse heterotopia which has opened the possibility of countless channels of local dialect competing directly with the channels of power. Undoubtedly such multiplicitous and global connectivity has sent creative thought in multiple directions…

summary	In many countries around the world, building codes are shifting from prescriptive- to performance-based for technical, economic, and social reasons. This move is made possible by progress in fire safety technologies, including the development of engineering tools that are required to implement performance codes. The development of performance-based codes follows a transparent, hierarchical structure in which there are usually three levels of objectives. The top level objectives usually state the functional requirements and the lowest level the performance criteria. Usually, one middle level exists, however, more levels can be used in this hierarchical structure depending on the complexity of the requirements. The success of performance-based codes depends on the ability to establish performance criteria that will be verifiable and enforceable. The performance criteria should be such that designers can easily demonstrate, using engineering tools, that their designs meet them and that the code authority can enforce them. This paper presents the performance criteria that are currently used by fire protection engineers in designing fire safety systems in buildings. These include deterministic and probabilistic design criteria as well as safety factors. The deterministic criteria relate mainly to life safety levels, fire growth and spread levels, fire exposure and structural performance. The probabilistic criteria focus on the incident severity and incident likelihood. Finally, the inclusion of safety factors permits a conservative design and allows for a smaller margin of error due to uncertainty in the models and the input data.
