title	Delivery Types And Communication Modalities In The Flat-Pack Furniture Design Critic
source	T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary	A computer-based design critiquing system analyzes a proposed solution and offers critiques (Robbins 1998). Critiques help designers identify problems as well as opportunities to improve their designs. Compared with human critics, today’s computer-based critiquing systems deliver feedback in quite restricted manner. Most systems provide only negative evaluations in text; whereas studio teachers critique by interpreting the student’s design, introducing new ideas, demonstrating and giving examples, and offering evaluations (Bailey 2004; Uluoglu 2000) using speech, writing, and drawing to communicate (Anthony 1991; Schön 1983). This article presents a computer-based critiquing system, Flat-pack Furniture Design Critic (FFDC). This system supports multiple delivery types and modalities, adapting the typical system architecture of constraint-based intelligent tutors (Mitrovic et al. 2007).

title	Architectural synthesis and optimization of digital systems
source	Eindhoven University of Technology
summary	High level synthesis means going from an functional specification of a digits-system at the algorithmic level to a register transfer level structure. Different appli-cations will ask for different design styles. Despite this diversity in design styles many tasks in the synthesis will be similar. There is no need to write a new synthesis system for each design style. The best way to go seems a decomposition of the high level synthesis problems in several well defined subproblems. How the problem is decomposed depends heavily on a) the type of network architecture chosen, b) the constraints applied to the design and c) on the functional description itself. From this architecture style, the constraints and the functional description a synthesis scheme can be derived.Once this scheme is fixed, algorithms can be chosen which fit into this scheme and solve the subproblems in a fast and, when possible, optimal way. To support such a synthesis philosophy, a framework is needed in which all design information can be stored in a unique way during the various phases of the design process. This asks for a design data base capable of handling all design information with a formally defined interface to all design tools. This thesis gives a formal way to describe both the functional representation, the register transfer level structure and the controller and the relations between all three of them. Special attention has been paid to the efficient representation of mutual exclusive operations and array accesses. The scheduling and allocation problems are defined as mappings between these formal representations. Both the existing synthesis algorithms and the new algorithms described in this thesis fit into this framework. Three new allocation algorithms are presented in this thesis: an algorithm for optimal register allocation in cyclic data flow graphs, an exact polynomial algorithm to do the module allocation and a new scheme to minimize the number of interconnections during all stages of the data path allocation. Cyclic data flow graphs result from high level behavioral descriptions that contain loops. Algorithms for register allocation in high level synthesis published up till now, only considered loop free data flow graphs, When these algorithms are applied to data flow graphs with loops, unnecessary register transfer operations are introduced. A new algorithm is presented that performs a minimal register allocation and eliminates all superfluous register transfer operations. The problem is reformulated as a multicommodity network flow problem for which very efficient solutions exist. Experiments on a benchmark set have shown that in all test cases all register transfers could be eliminated at no increase in register cost. Only heuristic algorithms appeared in literature to solve the module allocation problem. The module allocation problem is usually defined as a clique cover problem on a so-called module allocation graph. It is shown that, under certain conditions, the module allocation graph belongs to the special class of comparability graphs. A polynomial time algorithm can optimally find a clique cover of such a graph. Even when interconnect weights are taken into account, this can be solved exactly. This problem can be transformed into a maximal cost network flow problem, which can be solved exactly in polynomial time. An algorithm is described which solves the module allocation problem with interconnect weights exactly, with a complexity O(kn2), where n is the number of operations In previous research, interconnection was optimized when the module allocation for the operations and the register allocation for the variables already had been done. However, the amount of multiplexing and interconnect are crucial factors to both the delay and the area of a circuit. A new scheme is presented to minimize the number of interconnections during the data path allocation. This scheme first groups all values based on their read and write times. Values belonging to the same group can share a register file. This minimizes the number of data transfers with different sources and destinations. Secondly, registers are allocated for each group separately. Finally the interconnect allocation is done. During the interconnect allocation, the module allocation is determined. The value grouping is based on edge coloring algorithms providing a sharp upper bound on the number of colors needed two techniques: splitting read and write phases of values and introducing serial (re-)write operations for the same value, make that even more efficient exact edge coloring algorithms can be used. It is shown that when variables are grouped into register files and operations are assigned to modules during the interconnection minimization, significant savings (20%) can be obtained in the number of local interconnections and the amount of global interconnect, at the expense of only slightly more register area.

title	The Intelligent Sketch: Developing a Conceptual Model for a Digital Design Assistant

summary	The computer is a relatively new tool in the practice of Architecture. Since its introduction, there has been a desire amongst designers to use this new tool quite early in the design process. However, contrary to this desire, most Architects today use pen and paper in the very early stages of design to sketch. Architects solve problems by thinking visually. One of the most important tools that the Architect has at his disposal in the design process is the hand sketch. This iterative way of testing ideas and informing the design process with images fundamentally directs and aids the architect’s decision making. It has been said (Schön and Wiggins 1992) that sketching is about the reflective conversation designers have with images and ideas conveyed by the act of drawing. It is highly dependent on feedback. This “conversation” is an area worthy of investigation. Understanding this “conversation” is significant to understanding how we might apply the computer to enhance the designer’s ability to capture, manipulate and reflect on ideas during conceptual design. This paper discusses sketching and its relation to design thinking. It explores the conversations that designers engage in with the media they use. This is done through the explanation of a protocol analysis method. Protocol analysis used in the field of psychology, has been used extensively by Eastman et al (starting in the early 70s) as a method to elicit information about design thinking. In the pilot experiment described in this paper, two persons are used. One plays the role of the “hand” while the other is the “mind”- the two elements that are involved in the design “conversation”. This variation on classical protocol analysis sets out to discover how “intelligent” the hand should be to enhance design by reflection. The paper describes the procedures entailed in the pilot experiment and the resulting data. The paper then concludes by discussing future intentions for research and the far reaching possibilities for use of the computer in architectural studio teaching (as teaching aids) as well as a digital design assistant in conceptual design.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

source	J.A. Clarke, J.W. Mitchell, and R.C. Van de Perre (eds.), Proceedings, Building Simulation '91 IBPSA Conference, pp. 367-374
summary	We describe the need for a joint effort between design researchers and simulation tool developers in formulating procedures and standards for integrating simulation into the building design process. We review and discuss current efforts in the US and Europe in the development of next-generation simulation tools and design integration techniques. In particular, we describe initiatives in object-oriented simulation environments (including the US Energy 'Kernel System, the Swedish Ida system, the UK Energy Kernel System, and the French ZOOM program.) and consider the relationship of these environments to recent R&D initiatives in design integration (the COMBINE project in Europe and the AEDOT project in the US).

summary	Spatial productivity is the first of the elements comprising sensMOD, a student elective that implemented a methodology addressing the exigent need of our time for transformation in the architecture, engineering and construction (AEC) sector. The second and third elements of sensMOD are parts and interaction which focus attention on the nature of complexity and connectivity in our networked world. The paper proposes a methodology that was used to guide the teaching of an elective for third year architecture students at a UK university. Its wider purpose is to contribute to discussion concerning the dysfunctional state of an AEC sector that needs to consider its productivity as projections of wider networks of resource and energy relationships. Henri Lefebvre's spatial theory (1991) guides the narrative and formulation of sensMOD.

summary	The computer approaches to the discipline of project near the fifties, with the idea that all the systems and processes can be object of mathematical simulation. However in the last times, the computers were used more in drawings than in the projects, “CADrafting is uncommon (...) and CADesign is almost nonexistent...” (STEVEN, 1991). At the same time it happened a surprising approach with to architecture schools. It stimulated more methodological approaches, and the subject moved, placing the computer as element transformer. The computers have really been changing the production and generation of documents, but the question is if it has been altering the method or process of elaboration of ideas. After so much search in direction to the computers it is time of thinking what was gotten with them and the problems that accompanies him. The work search to discuss the subjects where the computer influences in the learning and the students’ development.

summary	In the international student-project "European Environmental Campus 91 TU Delft Dordrecht" 20 students from 13 European countries worked in september 1991, during three weeks on "EcologicalSketches for the Island of Dordrecht". They worked on four different scales: the region isle of Dordt / the district Stadspolders / the neighbourhood I the house and the block. The environmentaltheme's Energy, Water, Traffic & Noise, Landscape & Soil were together with spatial analyses combined with the different scales. This combination was organised following the scheme mentioned below. The characters stand for the students. During the first period they worked in research groups, during the last period more in design groups. For instance: student L works in the beginning with the students B, G and Q in the research group water. In the last period sheworks with K, M, N and 0 in the design group Neighbourhood. Those students worked earlier in the other research-groups and contribute now in the design-group their thematic environmental knowledge. The results were presented to the Dordrecht council, officials and press. In the next project in september and october 1993 we started earlier with the design groups. Ten Dutch and ten "Erasmus" students worked for six weeks on proposals for the Vinex location Wateringenthe Hague. Each morning they worked in the research groups each afternoon in the design groups. The research groups used the EcoDesign Tools, small applications in Excel on Apple Macintoshto quantify the environmental pressure.

summary	The need to explore development techniques in computer-based design is reviewed. Some premises are given for design development using computers, including integrating multiple representations, the use of object-based modeling and the importance of visual analysis and 3-D modeling. We then present techniques used in a UCLA design studio that explored methods of computer-based design development based on these premises. The two main methods used were hierarchical object structures and multi-representational coordination. They were applied using conventional CAD systems. Some lessons learned from this class are reviewed.

title	TEAnO or the computer assisted generation of manufactured aesthetic goods seen as a constrained flux of technological unconsciousness
source	International Conference on Generative Art
summary	TEAnO (Telematica, Elettronica, Analisi nell'Opificio) was born in Florence, in 1991, at the age of 8, being the direct consequence of years of attempts by a group of computer science professionals to use the digital computers technology to find a sustainable match among creation, generation (or re-creation) and recreation, the three basic keywords underlying the concept of “Littérature potentielle” deployed by Oulipo in France and Oplepo in Italy (see “La Littérature potentielle (Créations Re-créations Récréations) published in France by Gallimard in 1973). During the last decade, TEAnO has been involving in the generation of “artistic goods” in aesthetic domains such as literature, music, theatre and painting. In all those artefacts in the computer plays a twofold role: it is often a tool to generate the good (e.g. an editor to compose palindrome sonnets of to generate antonymic music) and, sometimes it is the medium that makes the fruition of the good possible (e.g. the generator of passages of definition literature). In that sense such artefacts can actually be considered as “manufactured” goods. A great part of such creation and re-creation work has been based upon a rather small number of generation constraints borrowed from Oulipo, deeply stressed by the use of the digital computer massive combinatory power: S+n, edge extraction, phonetic manipulation, re-writing of well known masterpieces, random generation of plots, etc. Regardless this apparently simple underlying generation mechanisms, the systematic use of computer based tools, as weel the analysis of the produced results, has been the way to highlight two findings which can significantly affect the practice of computer based generation of aesthetic goods: ? the deep structure of an aesthetic work persists even through the more “desctructive” manipulations, (such as the antonymic transformation of the melody and lyrics of a music work) and become evident as a sort of profound, earliest and distinctive constraint; ? the intensive flux of computer generated “raw” material seems to confirm and to bring to our attention the existence of what Walter Benjamin indicated as the different way in which the nature talk to a camera and to our eye, and Franco Vaccari called “technological unconsciousness”.

summary	I have been working on an architecture representation system in India since 1991; that markedly deviates from the need of traditional drawings as we know. Over three million square feet of work has been done that took advantage of this system as it was being developed. The system has now matured sufficiently to be put into practice as a comprehensive architectural system of practice. It takes advantage of creation of just-in-time dynamic multi-organizations that can get formed (and dismantled) over the Internet on a project to project basis. The raison d’être of the representation system is that it would expose the “source-code” (metaphorically) of any work of architecture to stakeholders, much the same way as an open-source software project exposes the internal representation to fellow developers. I believe the design of architecture must go through an “open source” process in order to produce socially responsible designs. Such a stance is explained in this paper. The paper also explains the system in detail; its mathematical basis and justifies the need for such an approach. It also explores how a collaborative practice can be put into place using the system in the context of Internet technologies.

summary	The concept of ODE (Open Design Environment) and corresponding system were presented in 1991. Then the new concept of NODE. which is networked version of ODE. was generated to make wide area collaboration in 1994. The aim of our research is to facilitate the collaboration among the various people involved in the design process of an urban or architectural project. This includes various designers and engineers, the client and the citizens who may be affected by such a project. With the new technologies of hyper medium, network, and component architecture, we have developed NODE system and applied in practical use of the collaboration among the various people. This study emphasizes the interactive 3-D design tool of NODE which is able to make realistic and realtime presentation with interactive interface. In recent years, ProjectFolder of NODE system, which is a case including documents, plans, and tools to proceed project., is created in the World Wide Web (WWW) and makes hyper links between a 3-D object and a text, an image. and other digital data.

summary	The Department of Real Estate and Project Management (BMVB) of the Faculty of Architecture at the Delft University of Technology has been working closely with Professor Spiro N. Pollalis of Harvard University, Graduate School of Design in Cambridge, USA since 1991. His case-based interactive seminars about the management of the design & construction process have been highly appreciated by many generations of students. In Spring 2000, Pollalis suggested to extend the scope of his involvement by introducing a remote teaching component, the subject of his research in the last few years. As Information and Communication Technology (ICT) in the Design and Construction Industry is part of his lectures, it was appropriate to provide the students with a first hand experience on the subject. In the following experiment, the teacher would remain in his office at Harvard while the interactive work and discussion sessions with 130 students in a full lecture room would take place in Delft as planned. The consequences this experiment has had for the course, for the techniques and facilities used, how teachers and students experienced these, and which conclusions and recommendations can be made, are the topics of this paper.

summary	The grid is a useful device for expressing design rules about the placement of elements in a layout. By expressing position rules for elements in relation to a grid, a designer can systematically organize decisions in a layout design problem. Grids and placement rules offer a discipline that can help a designer work effectively to lay out complex designs, and it can also facilitate group design work. Unfortunately, computer supported drawing systems often cannot support this way of working because they lack a sufficiently rich implementation of grids. The Grid Manager module of the CoDraw program shows enhancements useful for architectural Computer Assisted Design. These enhancements would enable more effective ways of using the computer as a design tool.

title	Programming 2-Way Constraints in CODRAW
source	1991. [8] p. : ill. includes bibliography
summary	Constraints based drawing programs require users to understand and manage relationships between drawing elements. By establishing constraint relationship among elements the user effectively programs the drawing's behavior. This programming task requires a more sophisticated visual interface than conventional drawing programs provide. Users must have available - in a convenient format - information about the structure of the constraints that determine the drawing's interactive edit behavior. This format must support editing and debugging. CoDraw is a constraint based drawing program that can be interactively extended by its users. This paper describes the CoDraw program and its programming interface

title	Utilización de un Sig Para la Formulacion de un Diagnostico Socioterritorial de la Ciudad de Buenos Aires (Use of a GIS for the Formulation of a Socio-territorial Diagnostic of the City of Buenos Aires)

summary	The use of a GIS to assist the elaboration of a socioterritorial diagnosis of the City of Buenos Aires. This paper is based on the result of two research projects sponsored by the University of Buenos Aires (Project AR01 0 and Project Cl-94). From the beginning of 1998 onwards these results have been applied to the development of a "socio-territorial diagnosis" of the City of Buenos Aires, an applied research project funded by the Government of the City of Buenos Aires and carried out by the Facultad de Arquitectura, Diseho y Urbanismo, Universidad de Buenos Aires (Research Unit: PROHAB). The main goal of the analysis was the identification of the spatial distribution pattern of of the selected variables, directed to the delimitation of "social areas". The facilities provided by the GIS allowed us to perform this task in an exploratory manner. An analysis of the 3405 census tracts of the City of Buenos Aires (the central part of the agglomeration) is presented here. A great number of indices were constructed based on variables of the Argentine National Census of Population and Housing referred to housing conditions, housing type, provision of services, origin of the population, educational level, etc. This paper describes the various steps necessary for the application of a GIS, including the digitizing of the cartographic base and the statistical elaboration of the census information (provided by the INDEC in magnetic medium). A colour cartographic output that can be considered a first approximation of the "social map" of the city in 1991 is presented.

title	Integrated Component-based Computer Design Modeling System: The Implications of Control Parameters on the Design Process
source	New Jersey Institute of Technology, Newark, NJ Graduate Thesis - Master's Program College of Architecture
summary	The design process is dependent on a clear order of integrating and managing all of the control parameters that impact on a building's design. All component elements of a building must be defined by their: Physical and functional relations; Quantitative and calculable properties; Component and/or system functions. This requires a means of representation to depict a model of a building that can be viewed and interpreted by a variety of interested parties. These parties need different types of representation to address their individual control parameters, as each component instance has specific implications on all of the control parameters. Representations are prepared for periodic design review either manually through hand-drawn graphics and handcrafted models; or with the aid of computer aided design programs. Computer programs can profoundly increase the speed and accuracy of the process', as well as provide a level of integration, graphic representation and simulation, untenable through a manual process. By maintaining a single control model in an Integrated Component-based Computer Design Modeling System (ICCDMS), interested parties could access the design model at any point during the process. Each party could either: 1. Analyze individual components, or constraints of the model, for interferences against parameters within that party's control; or 2. Explore design alternatives to modify the model, and verify the integration of the components or functions, within the design model, as allowable in relation to other control parameters.

title	SIMULATIONS OF ARCHITECTURAL PROJECTS: METHODS AND APPLICATIONS AT FULL-SCALE
source	Proceedings of the 3rd European Full-Scale Modelling Conference / ISBN 91-7740044-5 / Lund (Sweden) 13-16 September 1990, pp. 53-64
summary	This paper briefly examines five interrelated themes concerning the use of full-scale simulation models in architectural projects, in the context of research and professional practice. First, the meaning of design is discussed. Second, a multi-functional interpretation of building performance is presented. Third, the main reasons for simulating design projects, in general, and for using full-scale models, in particular, are summarized. Then the antecedent or prerequisite conditions for public participation to occur effectively are discussed. Finally, an overview of the use of full-scale simulation models in European workshops enables us to table four ma n classes of functions for full-scale models.

summary	The LEMA presents Strategy II, the new version of his CAL software in thermal design of building. Based on his latest experiences using the first prototypes, the present programme provides an complete human interface and interesting tools for decision taking. A first educational experience with this software is described. Strategy II has been studied in 1990 by two twin teams: one is the LEMA (Laboratoire d'Etudes Méthodologiques Architecturales) and the other one is the CTE (Centre des Technologies de l'Education), parts of the University of Liège, in Belgium.
