title	DEVELOPMENT OF A HELP TOOL IN ARCHITECTURAL ACOUSTICS SIMULATION ADAPTABLE IN A MODELISATION CAD SYSTEM
source	Ph.D. Thesis, Order number 2642, University of Bordeaux 1, 2002, France
summary	The aim of the proposed research in this thesis is the rapprochement of the acoustical conception and simulation with the architectural conception in order to give the architect the means to appreciate and evaluate the acoustical results, facilitate his collaboration with the acoustician, and, finally, allow him to have a help base during his architectural conception for acoustical simulation. This is proposed by the realisation of a plate-form of help adaptable to an architectural modelisation C.A.D. program, integrating acoustical calculate motors, graphical modules and research developed. This research concerns the definition of different processes of modelisation and simplification of architectural models for acoustical simulation, the translation of the acoustical results in an architectural way, the integration of an architectural approach to the acoustical conception, and an acoustical integrated multimedia database.

title	Real-time remote 3D digitizing and modelling
doi	https://doi.org/10.52842/conf.ecaade.2006.128
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 128-131
summary	This paper describes a procedure that feeds remotely a modelling system with geographical coordinates and the relative measurements taken in place in order to model dynamically new entities in real-time. The operation of this system is based on methodologies that are commonly used in telegeoprocessing – telegeomonitoring systems and its purpose is to simulate in real-time an existing environment using the captured measurements. The direct input of geographic data to the proposed system, which is adapted to a modelling environment (CAD or GIS), triggers the creation of new 3D entities in real-time (points, linear or area features), as it could be done with a traditional tablet digitizer. Simultaneously, the proposed system represents thematically the properties of the modelling entities (according to the measured values) over a 3D mesh. The aim of the suggested system is the remote registration of additional spatial information, their adequate treatment and adjustment via special developed interfaces, including their representation via developed software which is applied in the AutoCAD environment because of its programming development support and its use by a variety of engineers.

title	Definition of a Method of Limits of the Simplification of a Hall Model in a CAD System to Diminish Falsification of Acoustic Simulation Results
doi	https://doi.org/10.52842/conf.ecaade.2005.695
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 695-704
summary	During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation. The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002). This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (Amphi- EAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.

summary	More and more sectors are entering Industry 4.0 but when we look around in the Architecture, Engineering and Construction industry, we do not see it happening. We wanted to investigate the reason behind this. Therefore, we conducted research among Hungarian design studios to find out what level of development they are at, and what the obstacles could be for implementing the latest technologies. This paper identifies the main problem we uncovered and discusses a possible solution. We explain what BIM Organisation Development is and why it is fundamental for architect studios who would like to enter Industry 4.0. We introduce the so-called Brick+Data Method, specifying its three essential development steps to get BIM technologies implemented and to make architect studios more efficient. Finally, we share our findings according to the feedback of the companies we worked with using this method.

title	Logic Programming for Concept Modelling and Support of Urban Housing Design : A Pilot Study
source	1990. 134 p. CADLINE has abstract only
summary	Starting from a case study of manual sketch design of a residential area, the authors develop a prototypical site plan for low to medium density housing. The layout keeps pedestrian and vehicular traffic separated and provides open green area as well as a concentrated urban atmosphere. The constituents of the prototype layout are identified and a system of concepts devised accordingly. This conceptual analysis is formalized, using a Horn clause logic notation. Aspects of the resulting logic model concerning design of walking lines and plazas are refined into a considerable amount of detail. This exercise in knowledge representation seems to indicate that it will be possible, within the logic programming paradigm, to implement computerized support systems able to cooperate with and simulate designers working with architectural design. The main result of the study is that logical analysis of a particular prototype design can result in a collection of quite general concepts which are potentially useful in many other context than that of the prototype, for other kinds of design tasks. The report concludes by recommending several lines or aspects of future research in this area

title	Vibrant Formations - Geometries and dynamic material systems
doi	https://doi.org/10.52842/conf.ecaade.2020.1.281
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 1, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 281-288
summary	The project Vibrant Formations presents a series of experiments based on the research of the behavior of granular materials. The experiments shown in the paper are seen as a link between native material geometries and designed geometries. The project perceives granular materials as an intelligent matter capable of creating distinct patterns and actively responding to the environment they are placed in. This attitude towards material positions the project in an opposition to standard 3D printing technologies, where materials are seen as a proto-matter that acquires its properties and capabilities first after being formed into computed geometries and 3D printed shapes. The project Vibrant Formations explores material properties of different granular materials and processes and materializes their behavior. It works with the phenomenon called "granular segregation" to achieve specific objects connected to material logic which resemble frozen, digitally simulated particle systems. The material properties found in the research are further utilized. The process of granular segregation is investigated and material geometries replaced by fabricated geometries. This leads to a semi-automatised interlocking system capable of assembling and disassembling.

summary	This paper describes some of the challenges of using a Massive Open Online Course (MOOC) framework system with a variety of digital content. Situated in the 'efficiency' paradigm of digital design methods and Computer Aided Architectural Design (CAAD) education, we allow participants to set their own schedules, meet demands that are appropriate for their abilities, and determine their own path. The content within this framework motivates students through life-like tasks and examples. This paper shares our experiences in CAAD education through a course curriculum developed by applying a variety of digital content. We have focused on resolving the problem of inefficient teaching of CAAD systems by developing a blended learning curriculum.

title	The VLSI Design Automation Assistant : First Step
source	5 p. Design Research Center, CMU, December, 1982. DRC-18-57-82. includes bibliography
summary	This paper describes an approach to VLSI design synthesis using both knowledge-based expert systems and data and control flow analysis. The authors are concerned with design synthesis as it proceeds from an algorithmic description of a VLSI system to a list of technology-independent registers, operators, data paths, and control signals. This paper discusses the development of the Design Automation Assistant from its first interviews with expert VLSI designers to its current prototype state. Four designs of a microcomputer are presented along with the changes in the knowledge base that created those designs

summary	This paper will relay the initial phase of a collaborative work within partners from the design discipline, systems engineering, and software engineering which deals with the interrelations of “network idea”, “systems thinking”, “collective design”, and “computation”. Vensim– a system dynamics modelling tool developed by Ventana Systems, Inc. in 1992 – has been used in an experimental first year design studio to engage students in systems thinking in the architectural design environment. It has been observed that this tool enabled most students to develop a multi-layered, complex and more controlled design logic and to amplify the cognitive processes at the beginning of the design education. We conclude that in order to fully realize systems thinking in the design process, new ways of integrating parametric design environments and system dynamic modelling environments needs to be investigated.

title	Graph visualization in computer-aided design: An exploration of alternative representations for GenerativeComponentsTM Symbolic View
doi	https://doi.org/10.52842/conf.caadria.2011.133
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 133-142
summary	In this paper we explore graph models used to illustrate the relationships between elements of designs in computer-aided design (CAD) systems. We discuss common limitations and ways to make such representations more usable and interactive. In order to study common problems of symbolic representations in CAD systems, we conducted a survey of a number of CAD applications that employ graph representations in their interface and provided comparative analysis of the properties of graph representations in these systems. As a case study we used Bentley GenerativeComponentsTM (GC) system - a parametric CAD application that uses graph (“symbolic”) view to visualize the structure of design. We conducted series of interviews with expert GC users that revealed many limitations of the GC symbolic view. To address these limitations, we developed alternative representations of symbolic view that aim at enhancing user experience with the system and reviewed these with expert GC users. As a result of our study, we developed a set of interactive prototypes using SHriMP1 visualization tool and Processing programming language. These provide improved ways of user interaction with symbolic representation, including better readability of the graph and, as a result, an improved support for design model analysis.

title	Coastal Infrastructure Design: Researching Sea-Waves and Textured Surfaces Interaction Using Physical and Virtual Wave Flumes
doi	https://doi.org/10.52842/conf.caadria.2024.1.445

summary	Projected global rise in sea level and intensification of storms place the shoreline at risk, requiring extensive investment in coastal defence infrastructure. These structures are designed to efficiently dissipate wave energy at the expense of ecological and landscape values. The aim of the research is to establish a multifunctional approach to coastal infrastructure. Within this framework, it proposes a method for utilising simulation tools to creatively shape the interaction of sea waves with coastal structures for scenic and ecological benefits. It sets two primary goals: to establish that computational fluid dynamics tools can be used by architects to design the interaction of sea-waves with solid surfaces. This goal is explored by creating a digital simulation of a physical wave flume facility, and running physical experiments to calibrate the virtual simulation tool. Secondly, it uses these tools to systematically explore the range of possibilities latent in wave-structure interaction by initiating basic research into the flow properties of different types of textured surfaces to improve the aesthetic and ecological performance of such structures.

title	CAD is Creative
source	CAD Creativeness [Conference Proceedings / ISBN 83-905377-0-2] Bialystock (Poland), 25-27 April 1996 pp. 163-167
summary	There is an avalanche increase in number of architectonic offices in which the CAD technique is a medium used in the process of projecting. Ways of using CAD programs and computers are the personal matter of every user. The problem we faced was how to use it in creative work. The most interesting moment in process of projecting is the time when the set of lines on computer screen changes in mind into the real architectonic object. The form generated on the screen is new and inspire to farther, this time creative search. We must say that CAD technique let us achieve creativity during projects which means that ability to projects of new things and that state increase together with the increase of using this tool and we consider the claim that CAD may be used in a creative way.

title	Will Media Influence Learning? Reframing the Debate
source	Educational Technology Research and Development (1):1-31
summary	This article addresses the position taken by Clark that media do not influence learning under any conditions. The article reframes the questions raised by Clark to explore the conditions under which media will influence learning. Specifically, it posits the need to consider the capabilities of media, and the methods that employ them, as they interact with the cognitive and social processes by which knowledge is constructed. This approach is examined within the context of two major media-based projects, one which uses computers and the other video. The article discusses the implications of this approach for media theory, research, and practice.

summary	This study focuses on spatial metaphors in digital interfaces that designers use in their modeling processes. When designers themselves perform an action by using a digital tool, they often make spatial inferences without realizing it, with the help of their mental models and established modeling experiences. In order to trace these implicit spatial metaphors, the spatial metaphors used by the designers were discussed through their verbal expressions. Within the scope of the pilot case study, the participants told each other the 3D models given to them verbally, and the other participant made the 3D model simultaneously with the narrative. The metaphors that the participant in the role of the narrator used with the intention of making a spatial description allowed the participant in the role of the modeler to build spatial relations. This study, which has the potential to provide a spatial framework for interfaces in the future, is a step toward designing new user interface metaphors.

title	Space is the Machine, with a Ghost Inside
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 157-173
summary	The purpose of this paper is to report efforts towards the construction of a model for urban spatial dynamics simulation, based on multi-agents and space. The underlying idea is to have urban space producers and consumers operating in a two-layer, two-circuit model. The first layer holds urban space and its successive transformations; a second layer contains agents related to space; the first circuit simulates space production, and a second one simulates space consumption. Relationship between layers is represented as objective spatial features that agents are submitted to (the machine) and subjective meanings agents attach to each spatial feature (the ghost). While space works always in the same way, meanings vary according to each agent’s background and context. Relationships between circuits are represented by means of a market game in which producers try to maximize their profits by gambling with their risks, whereas consumers try to foresee the spatial distribution of local externalities that maximizes their utilities and investments. Urban Spatial Features are captured through centrality and land use patterns; every single agent’s action leads to changes in both patterns. Producers’ profit is a function of built form location. Consumers’ local externalities are concerned basically with present and future services. The model iteration is twofold: first it generates and allocates a number of built forms within a previously determined spatial system (a cellular matrix, for example), and second it allocates users to built forms. Population of users have its social profile and growth rate externally determined. Built form allocation is decided on the basis of a combination of profitXrisk perspectives. Users’ locational choice is supported by accessibility to services and present/future neighbourhood profile. Built form allocation works as parameter for users’ locational assessment, whereas users’ choices are used as parameters for developers. The model tends to adjust itself, in terms of quantities and types of built forms to be erected, although through a market lag of some iterations. Allocations are always made through weighted draws, so that mutations (non deterministic allocations) do occur.

title	Transducer: 3D Audio-Visual Form-Making as Performance
source	AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 285-291
summary	This paper describes Transducer, a prototype digital system for live, audio-visual performance. Currently the process of editing sounds or crafting three-dimensional structures on a computer remains a frustratingly rigid process. Current tools for real-time audio or visual construction using computers involve obtuse controls, either heavily GUI'ed or overstylized. Transducer asks one to envision a space where the process of editing and creating on a computer becomes a dynamic performance. The content of this performance may be sufficiently complex to elicit multiple interpretations, but Transducer enforces the notion that the process of creation should itself be a fluid and transparent expression. The system allows a performer to build constructions of sampled audio and computational three-dimensional form simultaneously. Each sound clip is visualized as a "playable" cylinder of sound that can be manipulated both visually and aurally in real-time. The transducer system demonstrates a creative space with equal design detailing at both the construction and performance phase.

source	AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 251-264
summary	This paper summarizes DIGITAL SKETCH, a workshop that took place over the course of two weeks in September 1998 at Designskolen Kolding, Denmark. DIGITAL SKETCH was an attempt to create a foundation course in design for the digital medium for students with strong visual design skills, but little to no computer experience. Teaching design on computers is commonly thought of as detailing the current version of the latest commercial software. As long as this is the case, design on computers will (quite rightfully) continue to get little respect from those designers using more traditional design methods. How can we find the "core" of this medium when faced with the constant onslaught of operating system upgrades and version 11.2 of software Y83? For DIGITAL SKETCH, we tried to demystify the process of controlling the computer. In this workshop we examined the meanings of the term "sketch" as it applies to the design process on the computer. Our hope was that by revealing some of the unique characteristics of the digital medium, we might develop new design processes in tune with this medium.

title	Mapping a Single Data Stream to Multiple Auditory Variables: A Subjective Approach to Creating a Compelling Design
source	Proceedings of the Third International Conferenceon Auditory Display, Santa FO Institute
summary	Representing a single data variable changing in time via sonification, or using that data to control a sound in some way appears to be a simple problem but actually involves a significant degree of subjectivity. This paper is a response to my own focus on specific sonification tasks (Kramer 1990, 1993) (Fitch & Kramer, 1994), on broad theoretical concerns in auditory display (Kramer 1994a, 1994b, 1995), and on the representation of high-dimensional data sets (Kramer 1991a & Kramer & Ellison, 1991b). The design focus of this paper is partly a response to the others who, like myself, have primarily employed single fundamental acoustic variables such as pitch or loudness to represent single data streams. These simple representations have framed three challenges: Behavioral and Cognitive Science-Can sonifications created with complex sounds changing simultaneously in several dimensions facilitate the formation of a stronger internal auditory image, or audiation, than would be produced by simpler sonifications? Human Factors and Applications-Would such a stronger internal image of the data prove to be more useful from the standpoint of conveying information? Technology and Design-How might these richer displays be constructed? This final question serves as a starting point for this paper. After years of cautious sonification research I wanted to explore the creation of more interesting and compelling representations.

title	The Codewriting Workbook: Creating Computational Architecture in AutoLISP
source	Princeton Architectural Press, New York
summary	Conceived as a primer for architects, artists and designers, The Codewriting Workbook introduces students and practitioners to basic programming concepts for computeraided design (CAD). Through a series of guided exercises using algorithmic functions, readers learn how to develop and write procedures for two-dimensional drawings and three-dimensional models. Each sequence of exercises starts with a simple concept and evolves into a family of possible solutions, including specifying and exploring a wide range of design alternatives, integrating parameters for controlling randomness, utilizing meteorological data, and developing complex patterns for laser-cutting and CNC-milling. Exercises are presented in AutoLISP, a widely accessible CAD programming environment. Forward by William J. Mitchell CD included, over 400 functions, 416 pages, 274 drawings

title	The Art of Spirolaterals
doi	https://doi.org/10.52842/conf.acadia.2001.408
source	Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 408-409
summary	The web site includes a series of images which is part of a larger set investigating the formation of two-dimensional designs leading to three-dimensional architectural forms using basic mathematical concepts. While investigating fractals and space curves, a mathematical figure called a "spirolateral" was encountered. A spirolateral is based on a square spiral with increasing length of turns and the turns repeating themselves. The turns can be all in one direction or certain turns can go the opposite direction. Angles other than 90 degrees can be used. The most interesting of these are ones that close on themselves, not all do. Investigating a series of possible turning angles, number of turns, number of repeats, and trying all revered turns, I identified over 10,000 spirolaterals that closed. This web site displays over 300 such spirolateral designs. In addition to investigating spirolaterals composed of straight lines, a series was developed that curves them. These designs are based on spirolaterals that are curved by antiMercator, circular, and inversion transformations. Figure 1 displays the 460 spirolateral, 4 turns at 60 degrees. Figure 2 and 3 display the same spirolateral with the antiMercator and Circular transformations applied. This web site includes galleries displaying the great variety of spirolaterals, interactive JAVA routines to display a series of spirolaterals, as well as, developing your own design, a technical description of spirolaterals, and the data for all the displayed images. My overall interest is to investigate methods that can develop forms that are in one sense predictable, but have the strong element to generate the unexpected. Using custom software enables an approach that allows variations to be investigated in a repeatable way, this enabling me to fine tune an idea by repetition and experimentation.
