title	Emergent Relations Self-Indexing Media for Case-Based Reasoning
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 73-82
summary	A priori indexing systems for case-based reasoning are unlikely to engender interesting, let alone creative, explorations. The problem is that they assume a predetermined knowledge and conceptual structure which neglect new and emergent relations. By allowing multiple labelling of entities, it can be shown that different orders of emergent relations can be derived on the fly without any conventional classification schemes. This gives a flexible, scalable, and most importantly, an associative reasoning system that is more likely to trigger interesting concepts which are technically “categorical errors” but seeds of creative thought.

title	Clay Robotics: Tool making and sculpting of clay with a six-axis robot
doi	https://doi.org/10.52842/conf.caadria.2016.579
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 579-588
summary	The objective of the project is to design a reproducible clay sculpting process with an industrial robotic arm using parametric con- trol to directly translate mesh geometry from Computer Aided Design (CAD) environment into a lump of clay. This is accomplished through an algorithmic design process developed in Grasshopper using the C# programming language. The design process is enabled by our robotics modelling and simulation library which provides tools for kinematics modelling, motion planning, visual simulation and networked com- munication with the robotic system. Our process generates robot joint axis angle instructions through inverse kinematics which results into linear tool paths realised in physical space. Unlike common subtrac- tive processes such as Computer Numeric Control (CNC) milling where solid material is often pulverised during machining operations, our process employs a carving technique to remove material by dis- placement and deposition due to the soft and self-adhesive nature of the clay material. Optimisation of self-cleaning paths are implemented and integrated into the sculpting process to increase pathing efficiency and end product quality. This paper documents the process developed, the obstacles faced in motion planning of the robotic system and dis- cusses the potential for creative applications in digital fabrication us- ing advanced machines that in certain terms exceed human capability yet in others are unable to reach the quality of handmade works of art.

title	Exploration & Validation - Making sense of generated data in large option sets
doi	https://doi.org/10.52842/conf.ecaade.2020.1.653
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. 653-662
summary	The project is a real-world case study where we advised our client in the selection of a viable and well-performing design from a set of computationally generated options. This process was undertaken while validating the algorithmic generative process and user-defined evaluation criteria through scrutinizing the other alternative options to ensure ample variability was considered. Optimisation algorithms were not ideal as low performing options were not visible to validate variability. We established variability by extracting the different groups of options, proving to the client that various operational behaviours were present and accounted for. In order to sieve through the noise and derive meaningful results, we employed methods to filter through thousands of options, including: k-means clustering, archetypal labelling and analysis, pareto front analysis and visualisation overlays. We present a sense-making and decision-making process that utilizes principles of genetic algorithms and analysis of multi-dimensional user-derived evaluation scores. To enable the client's confidence in the computational model, we proved the effectiveness of the generative model through communicating and visualizing the impact of different criterias. This ensured that operational needs were considered. The visualization methods we employed, including pareto front extraction and analysis eventually helped our clients to arrive at a decision.

summary	We present the initial findings of our research project aiming at development of a 3D-printing process for wood composites. The 3D-printing method employed is based on material extrusion principle and utilizes industrial robotics for position and motion control. The unique characteristic of our approach is in the development of the material where we employ exclusively organic components for both the matrix and reinforcement; a decision informed by prioritizing environmental considerations.

title	Cognition-based CAAD. How CAAD systems can support conceptual design
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 521-531
summary	This paper introduces the concept of cognition-based CAAD. Protocol analysis and a content-oriented coding scheme are utilised to produce cognitive results of designers’ behaviour. This empirical analysis suggests that the speed of thought and vagueness among actions are the main areas to be supported by any cognition-based CAAD system. Three different modes of design thinking are presented as the basis of a possible CAAD system.

title	Design Concept Learning Using Inductive Learning Techniques in an Integrated Design Support System
doi	https://doi.org/10.52842/conf.caadria.2000.201
source	CAADRIA 2000 [Proceedings of the Fifth Conference on Computer Aided Architectural Design Research in Asia / ISBN 981-04-2491-4] Singapore 18-19 May 2000, pp. 201-213
summary	Design and learning are closely related activities. Conceptual design is characterized by the uncertainties of the issues related to the design problem, design requirements, design constraints, and design solutions. Organizing design information to define an area of design problem within which these issues are gradually structured involves an inductive learning process. This paper tackles this learning process during conceptual design by utilizing inductive learning and concept formation techniques. The paper presents the architecture and the implementation of a Design Concept Learning System (DCLS) within a multi-agent architecture. It then reports on how the DCLS can be applied to conceptual design tasks in different domains.

title	An Artificial Intelligence Approach to Industrial Design Support
source	International Conference on Generative Art
summary	The process of Industrial Design extends from market analysis, conceptualization, form generation to performance prediction, engineering analysis and user analysis etc. This requires a wide range of design knowledge and techniques from different disciplines. Computer-based support to industrial design is limited because the majority of the CAD systems deal with only geometric models and representations. The recent advancement in generative techniques utilizing evolutionary computation methods provides an opportunity for the study of more creative and systematic ways of supporting the industrial design process. However, one of the problems associated with the existing generative techniques is the difficulty in evaluating a large number of solutions generated by a generative system. This paper addresses this problem by presenting a system framework for industrial design support through an integrated application of Artificial Intelligence techniques.

title	A representation of context for computer supported collaborative design
source	Automation in Construction 10 (6) (2001) pp. 715-729
summary	This paper presents a computational definition of design context and discusses its role for collaborative design. A brief review of design representation and modeling approaches is given first. This is followed by a discussion on the necessity for modeling design context in collaborative design. This discussion provides a basis for a definition of design context and a description of Artificial Intelligence (AI) methods for representing and reasoning about this design context. The development of an intelligent collaborative design system supporting context management is presented. Finally, the limitations of our current approach to representing design contexts, and possible ways for future improvement are discussed.

summary	Graduate Institute of Architecture, National Chiao Tung University, Hsinchu, 30050, TAIWAN Computer simulation technology was used well in virtual archaeology during the past five years but will be insufficient gradually in the future, just because the simulations have extended from static issues, such as implements, architectures and a whole city, to motional issues, such as cultural activities in a city. This paper developed a digital reconstruction procedure that integrated three main technologies including 3D scanner, motion capture and virtual reality cave (VR Cave), and implemented it to virtually reconstruct Chang-an City that existed 1400 years ago but disappeared now. The results of the simulations are not only realistic enough to being inside but also highly approved by archeologists, art historian and architects.

source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 433-440
summary	The development of better User Interface (UI) and Tangible User Interface (TUI) for 3D modeling has lasted for decades. With the popularity of free form style achieved by algorithmic methods, the existing solutions of UI/TUI for CAD are gradually insufficient. Neglecting the steep learning curve of algorithmic design requiring solid background of mathematics and programming, the common drawback is the lack of interactivity. All actions rely heavily on mental translations and experimental trial and error. In this research, we try to realize the idea of interactive algorithmic design by developing a tangible calligraphic brush, with this device designer can intuitively adopt algorithmic methodology to achieve highly creative results.

summary	This study introduces a methodology for the evaluation, among a set of possible plans and/or policies, of a transport system which could reduce the effects of the network congestion on an urban area. Hence it is proposed a procedure which contains a new element compared with the current methodologies that is the final user’s evaluation of the examined system by turning to the application of the contingent valuation method, a technique like stated preferences. The approach we propose is based on the necessity for a determination of an optimal solution to the urban congestion to be established on the politic acceptability by the final user. Solutions which result virtually feasible for a public administration both on a technique and economic point of view often meet hostility by individuals. Consequently, it would be interesting for policy makers to adopt a process of valuation which could let to understand the user’s sensitivity and hostility towards specific configurations of the system, chosen as solution to decongestion (traffic calming, roadpricing, auto-free zones) and consequently to make less unpleasant the strategy to be carried out to control congestion (Harrington et al., 2001). In this way, a user does not judge the implementation of a set of projects made by a decision-maker as imposition and he is willing to pay in order to fulfil the chosen scenario. Finally we describe an application of the proposed methodology relating the definition of the integrated transport system in the metropolitan area of Bari, chief town of Apulia.

title	Development of automated weather-unaffected building construction system
source	Automation in Construction 6 (3) (1997) pp. 215-227
summary	An automated weather-unaffected building system has been developed which aims at creating a system for producing an attractive building system for the next generation. This system makes improvements with regards to problems pertaining to labor productivity, and creates a comfortable production environment for the new type of engineers of the future. It can provide high quality building at a low cost. This system is based on the procedure that after the uppermost floor of the building is assembled on the ground level, various automated mechanical devices necessary for structural work are installed. The structural body of the building is constructed one floor at a time and each part in sequence under weather proof working conditions. Each is raised to the uppermost floor by means of a jack system. This paper reports the summary and execution of the above automated weather-unaffected building construction system.

source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 427-432
summary	The system proposes to apply the results of the investigation in the task of architecture de-structurizing the idea in order to free the capacity of thought. One works in a three-dimensional way with models built, using discarded material. It is processed by means of digital media, giving a series of images which have been selected. One uses on them different systems of lighting changing the number of lights, the position in space and the distances. Like that one obtains different shadows on a surface; those shadows work in similar form with “eyes” of possible architectural forms. They are digitally processed according to the desired objectives. Several of them are combined adding and removing elements, which makes them dynamic in time. This technique tries to develop a new tool for students who may find the idea spontaneously, with the freedom of thought in three-dimensions like a new form of looking at architecture.

title	The Cost Effectiveness of Typical Materials in Relation to Indoor Comfort of Passive Cooling Strategies Appropriate for Small One Story House in Chiang Mai, Thailand
doi	https://doi.org/10.52842/conf.caadria.2008.251
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 251-258
summary	This study suggests that the appropriate building materials are those most common in a given locale considering simple appropriate natural passive cooling strategies for a typical small one story house to apply toward traditional living. Two different weather conditions, hot-dry and hot-humid, were selected representing seasonal climates. Computer simulations on thermal effect and ventilation were processed by CFD software, FLOVENT 6.1. Ordinary building materials have been chosen to compare relationship between outdoor-indoor temperature differences and their costs. It was found that natural cross ventilation is the best solution for a small one-story house with additional assistance of thermal mass effect. The most effective typical wall and roof materials are the conventional 10cm brick wall and 5mm corrugated fibrous cement roof which give the best performance for comfort at a unit investment cost. Simulated results also showed that the same house with typical horizontal ceiling presents better comfort than non-ceiling case.

title	From Immersive to Physical Sketches: A New 3D Representation Mode During Ideation
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 253-263
summary	This paper presents a new representation mode during ideation based on the use of immersive 3D sketches and their digital fabrication. This work explores freehand immersive 3D sketches of design objects printed at real scale. Freehand 3D vectors were optimized thanks to parametric geometries generated for 3D printing. Our approach aims to take advantage of real-scale immersive 3D sketches, while enriching the 3D perception of proportions and shapes by 3D printing the physical sketches. 3D printing usually requires high-level of 3D modeling skills and this can be challenging during ideation. This technique will allow to reduce the steps going from: 2D sketches – 3D modeling – fabrication to 3D sketches – 3D physical sketches. The hybridization of immersive life-size sketching and 3D printed life-sized sketches, could positively impact ideation by allowing a better grasp of the 3D shapes’ scales and proportions.

title	pCM (pure C Music): a real-time music language
source	International Conference on Generative Art
summary	In order to put to work the facilities offered by the gesture interfaces realised at cART project of CNR, Pisa, I started writing basic libraries for processing sound and for driving the gesture interfaces. In the long run the framework became a very efficient, stable and powerful “music language” based on pure C programming, that is “pure-C-Music”, or pCM. This programming environment gives the possibility to write a piece of music in terms of synthesis algorithms, score and management of data streaming from gesture interfaces. The pCM framework falls into the category of the “embedded music languages” and has been implemented using one of the most popular C compilers or better, multiplatform development systems: Metrowerks’ Code Warrior. As a result a pCM composition consists of a CW project which includes all the necessary libraries, including a DSP.lib consisting of a number of functions able to implement in real-time the typical synthesis and processing elements such as oscillators, envelope shapers, filters, delays, reverbs, etc. The composition itself is a C program consisting, mainly, of the Orchestra() and Score() functions. Everything here is compiled into machine code and runs at CPU speed.

title	Deep learning surrogate models for spatial and visual connectivity
source	International Journal of Architectural Computing vol. 18 - no. 1, 53-66
summary	Spatial and visual connectivity are important metrics when developing workplace layouts. Calculating those metrics in real time can be difficult, depending on the size of the floor plan being analysed and the resolution of the analyses. This article investigates the possibility of considerably speeding up the outcomes of such computationally intensive simulations by using machine learning to create models capable of identifying the spatial and visual connectivity potential of a space. To that end, we present the entire process of investigating different machine learning models and a pipeline for training them on such task, from the incorporation of a bespoke spatial and visual connectivity analysis engine through a distributed computation pipeline, to the process of synthesizing training data and evaluating the performance of different neural networks.

title	Neutral intelligent CAD communication: information exchange in construction based upon a minimal schema
source	KTH Stockholm
summary	An improved information exchange is frequently proposed as one solution to the inefficiency problems which the construction industry is suffering from today. Such an improvement is very dependent of the use of information technology, IT. To enable an advanced use of IT, there is a need for integrated project communications frameworks and integrated industry wide information. This thesis discusses how product models can be used to improve the information exchange from design to construction. Today there are several approaches to product modelling. Some researchers propose very detailed models whereas others propose generic models with fewer concepts. In this area there is a close connection between research and standardisation, which is carried out by organisations such as the ISO STEP committee and the International Alliance for Interoperability. To get acceptance for a standard proposal, it has to be accepted by both users and standardisation bodies. Thus this research, in addition to the technical requirements on information content and structure, also discusses success factors for standardisation, implementation and usage. In order to define important requirements on a product model for information exchange between design and construction, current research, development and standardisation in the field of product modelling was studied. This thesis advocates a minimal approach in the number of concepts used in a product model, in combination with an external building element classification, following national industry practice. The minimal NICC schema, developed during this research, was tested in a prototype and test study. Three applications were tested: PreFacto (planning tool), Microsoft Project (time scheduling tool) and Calc3(cost estimation tool). From the CAD-system MCAD, NICC files with the building objects were created and transferred into a relational database from which the three applications received their specific input files. The results of the evaluation of the NICC schema and the test study demonstrated that a product model based on few concepts can manage the required information exchange.
