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

title	Awareness Space in Distributed Social Networks
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 615-628
summary	In the real work environment we are constantly aware of the presence and activity of others. We know when people are away from their desks, whether they are doing concentrated work, or whether they are available for interaction. We use this peripheral awareness of others to guide our interactions and social behaviour. However, when teams of workers are spatially separated we lose 'awareness' information and this severely inhibits interaction and information flow. The Theatre of Work (TOWER) aims to develop a virtual space to help create a sense of social awareness and presence to support distributed working. Presence, status and activity of other people are made visible in the theatre of work and allow one to build peripheral awareness of the current activity patterns of those who we do not share space with in reality. TOWER is developing a construction set to augment the workplace with synchronous as well as asynchronous awareness. Current, synchronous activity patterns and statuses are played out in a 3D virtual space through the use of symbolic acting. The environment itself however is automatically constructed on the basis of the organisation's information resources and is in effect an information space. Location of the symbolic actor in the environment can therefore represent the focus of that person's current activity. The environment itself evolves to reflect historic patterns of information use and exchange, and becomes an asynchronous representation of the past history of the organisation. A module that records specific episodes from the synchronous event cycle as a Docudrama forms an asynchronous information resource to give a history of team work and decision taking. The TOWER environment is displayed using a number of screen based and ambient display devices. Current status and activity events are supplied to the system using a range of sensors both in the real environment and in the information systems. The methodology has been established as a two-stage process. The 3D spatial environment will be automatically constructed or generated from some aspect of the pre-existing organisational structure or its information resources or usage patterns. The methodology must be extended to provide means for that structure to grow and evolve in the light of patterns of actual user behaviour in the TOWER space. We have developed a generative algorithm that uses a cell aggregation process to transcribe the information space into a 3d space. In stage 2 that space was analysed using space syntax methods (Hillier & Hanson, 1984; Hillier 1996) to allow the properties of permeability and intelligibility to be measured, and then these fed back into the generative algorithm. Finally, these same measures have been used to evaluate the spatialised behaviour that users of the TOWER space show, and will used to feed this back into the evolution of the space. The stage of transcription from information structure to 3d space through a generative algorithm is critical since it is this stage that allows neighbourhood relations to be created that are not present in the original information structure. It is these relations that could be expected to help increase social density.

title	Road hierarchy and speed limits in Brasília/Brazil
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title	A Data Flow Approach to Procedural Modeling
source	IEEE Computer Graphics and Applications January, 1984. vol. 4: pp. 16-26 : ill. (some col.). includes bibliography.
summary	Computer graphics tasks generally involve either modeling or viewing. Modeling combines primitive building blocks (polygons, patches, etc.) into data structures that represent entire objects and scenes. To visualize a modeled object, its data structure is input to appropriate viewing routines. While a great deal has been done on modeling and viewing with geometric primitives, little has been published on the use of procedural primitives. A procedural model is a step-by-step guide for constructing a representation of an object or process, i.e., a program. It is also a function, a 'black box' with a set of inputs and outputs. Two questions are especially pertinent to the work presented in this article
keywords	First, what are the advantages of both data flow methods and procedural modeling? Second, how can such models be used in composition? computer graphics, modeling, information, management

title	Efficient Algorithms to Globally Balance a Binary Search Tree
source	Communications of the ACM. July, 1984. vol. 27: pp. 695-702. includes bibliography
summary	A binary search tree can be globally balanced by readjustment of pointers or with a sorting process in O(n) time, n being the total number of nodes. This paper presents three global balancing algorithms, one of which uses folding with the other two adopting parallel procedures. These algorithms show improvement in time efficiency over some sequential algorithms when applied to large binary search trees. A comparison of various algorithms is presented

title	A Depth-Coherence Scanline Algorithm for Displaying Curved Surfaces
source	Computer Aided Design. March, 1984. vol. 16: pp. 91-101 : ill. includes bibliography
summary	A scanline algorithm is presented which generates a realistic picture of a solid object bounded by curved surfaces. Externally, a surface is described by parametric equations. The internal representation is comprised of meshes of cubic splines which may be subdivided. Memory is saved by delaying subdivision, and by using a novel garbage collection technique. Time is saved by exploiting depth coherence. A viewpoint and scanline fix a cross-section represented as a set of curves. There are usually only a few of these to compare, and the curve nearest the viewer often remains nearest over much of its length

title	A Database Management Approach to CAD/CAM Systems Integration
source	December, 1984. 13 p. : ill. includes bibliography
summary	Facilitating the communication between different CAD/CAM systems is rapidly becoming an important issue, as more systems reach the market. A solution to the communication problem can be found if it is considered part of the more general problem of managing the complex information associated with the representation of physical artifacts and environments in the memory of computers, thereby accounting for the operators that are used for accessing the data as well as the data itself. Database management systems have provided powerful solutions to information management problems in a variety of disciplines and enjoy a broad and rigorous research foundation. If the techniques, methods and systems that were developed for database management could be utilized for CAD/CAM integration, they would save a considerable duplication of effort, enhance the integrity of the data, and bring to bear the results and advances that have been achieved over a long period of hard work

title	Automatic Finite- Element Mesh Generation from Geometric Models : A Point Based Approach
source	ACM Transactions on Graphics. October, 1984. vol. 3: pp. 287-311 : ill. includes bibliography
summary	A novel algorithm for automatic finite-element mesh generation is described. It uses constructive solid geometry to provide the geometric data for the object to be meshed. The geometric definition of the object and a value for the required mesh density are the only inputs. The method consists of two stages: point generation and mesh construction over the points. It has been implemented in two dimensions and is capable of generating predominantly 'good' quadrilateral elements. Triangular elements are only created in circumstances under which quadrilateral elements are not feasible

title	Relational Database Modeling of Building Design Data
source	Computing in Civil Engineering Conference Proceedings (3rd : 1984 : San Diego). American Society Of Civil Engineers, pp. 364-371. CADLINE has abstract only
summary	This paper discusses the use of a relational database for representing the data gathered and derived during the building design process. In doing so, it considers the complexity of the relationships among a structure's topology, geometry, and attributes, and the critical requirements they impose on the development of a building design database. In the broad arena of computer-aided design, relational database management systems are establishing themselves as useful engineering tools. This is occurring at a time when engineers and architects are moving toward centralized and integrated databases of design information. In such a database, information is directly and readily available to all members of the design team, allowing them to work concurrently on an accurate representation of a wide variety of engineering design data. This paper presents the use of a relational database to model building design data and shows that the relationships among topology, geometry, and attributes can be successfully modeled relationally. The feasibility of interaction between engineering applications programs and the database is also indicated. Although the paper concentrates on structural design data for buildings, the relational model can also be used to represent the data of other engineering design disciplines as well as the data for other structures, assemblies, systems, and processes

doi	https://doi.org/10.52842/conf.ecaade.1984.x.u6h
summary	In Belgium there are two possibilities to study architecture, it can either be done at a higher institute or academy, or at a university. At the higher schools of architecture the computer equipment has just been installed during the last years, and teaching of CAAD is not yet integrated. There exists only a general computer course. At the universities hardware has been available since several years, and software has been developed. The following programs have been implemented in Liege : LPB1, LPB2, LPB3, LPB4 (energy analysis), FEASIBILITY (to obtain acceptable values for the main global parameters of a design), VOLUME, (3D modelling for building modelisation and manipulation) and TYPOLOGIE (for the determination of classes for the energetic behaviour of residential buildings).

title	Climate and Building Design - Tradition, Research and Design Tools
source	Energy and Buildings. 1984. vol. 7: pp.55-69 : ill. tables. includes bibliography
summary	Important design parameters that influence the building thermal behavior and in particular natural cooling are discussed. Among these design parameters are: ventilation, evaporation, proper shading, orientation of the building and its proportions with respect to the orientation, the color of the building's envelope and its conductivity, the thermal mass of the building, night radiation to the sky and the stack effect. The latter is the katabatic and anabatic cooling. Different design tools aimed at the study of the influence of the climatological parameters on the form andÔ h)000*°° ÔŒ characteristics of buildings were developed in recent years. These tools help architects in designing houses with improved indoor thermal conditions without mechanical means, or with minimum energy consumptions. Several design tools, as well as design considerations and traditional constructions, are presented
