title	Modelling effects of cad on concrete construction using production graphs
source	The Int. Journal of Construction IT 1(4), pp. 39-50
summary	Quantitative statements on effects of CAD systems are needed to manage their use in concrete construction, but are hard to make. This paper describes an approach to model the effects of CAD systems on concrete construction. The approach is based on the concept of 'the market value of information commodities', and uses graph theory to build a formal model of the construction process. The formal model, so-called production graph, allows for investigation and quantification of the effects of CAD systems, which depend on their so-called value adding dimensions. An example of application of the approach is provided. Experiences with this approach are very good. General patterns between the value adding dimensions of CAD systems and their effects on production graphs must be determined to develop a descriptive and predictive model. Case-studies are being done to identify these general patterns.

title	BIM Add-on Tool for Automated CUI Calculation
doi	https://doi.org/10.52842/conf.caadria.2014.305
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 305–314
summary	The Building and Construction Authority (BCA) of Singapore established Sustainable Construction Master Plan with the goal of achieving a Sustainable Singapore Blueprint. The Concrete Usage Index (CUI) is a part of Sustainable Construction scoring under Singapore’s ‘Green Mark’ system. Since computation of CUI score was formerly calculated manually without the use of BIM software, it was an inaccurate and tedious process. Although calculation of CUI is currently much faster through the use of BIM software, it still faces challenges. The objective of this project is to address those challenges by creating a BIM addon tool which is capable of automating the process of CUI calculation with minimum user input. Our intention is to help the industry to calculate CUI systematically and efficiently while promoting the adoption of BIM.

title	Some Phenomena of Touch in Study Models
doi	https://doi.org/10.52842/conf.caadria.2005.277
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 1, pp. 277-287
summary	The senses of “Touch” bring people the feeling of reality, and human beings can always naturally sense the tactile impression. Hence we touch things and our sense tells us that our hands are touching something (Hinckley et al. 1999). Comparing to the tools used by designers between traditional and new digital media in the design process, the most difference is in the sense of touch. This paper focuses on the sense of touch to point out the haptic experience which have ignored by the past in design process. Four phenomena will be discussed in details and some useful suggestions given for future study.

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	Exploring Phygitalization in Architecture: Comparative analysis of the reality of digital and physical experiences in relationships of humans and space
doi	https://doi.org/10.52842/conf.ecaade.2024.2.169
source	Kontovourkis, O, Phocas, MC and Wurzer, G (eds.), Data-Driven Intelligence - Proceedings of the 42nd Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2024), Nicosia, 11-13 September 2024, Volume 2, pp. 169–177
summary	Contemporary designers utilize extended reality (XR) to merge the physical and digital realms, aiming to create immersive user experiences, a concept known as "phygitalization." However, current studies predominantly focus on the visual aspects of XR, resulting in underdeveloped XR systems. This research aims to address this gap by examining the role of haptic experiences in enhancing immersion within the virtual environment, thereby bridging the divide between the physical and digital worlds. The research methodology involved a literature review to explore relevant terminologies related to physics, space, experience, senses, and human perception. Subsequently, an experiment was conducted to investigate the impact of connectivity between the physical and digital worlds on human perception. The experiment involved participants using a VR headset to interact with virtual "sand" and then directly interacting with different physical materials that have similarities and differences to the virtual environment, aiming to investigate (a) the incorporation of real objects in (b) interior and exterior virtual settings and (c) the disparities between physical and virtual materials. The study results showcased that by combining XR with physical haptic experiences, it is possible to enhance immersion in the virtual environment, contributing to the development of “Data-Driven Intelligence”, while recognizing that it may not fully substitute the physical world. This research seeks to explore the relationship between humans and space in both digital and physical experiences and paves the way for investigating how the integration of XR in architectural contexts can influence human perception, sensory abilities, and experiential encounters.

title	Interactive Mapping between Knowledge Level and Symbol Level with Geometry. A KL-Model for Design Space Exploration
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. 157-166
summary	Design space exploration is long-standing motivating ideas in computer-aided design. It realises this vision through a model of design states for making and moving amongst states and an organisation of states into a structure called a design space. Using a design space structuring mechanism based on a subsumption relation, this paper sketches a theory called Geometric Typed Feature Structures (GTFS) to preserve the formal properties of the design space movement algorithms for geometry. It also provides the theory for incorporation of user-guided exploration in the design space. Consequently, the clear division between knowledge level and symbol level, such that functional decomposition •• formal symbol level and design •• model symbol level, disappears. We can therefore use the same subsumption relation to structure the design space exploration interactively. Such interactive mapping between knowledge level and symbol level provides the fine-grained opportunities for user intervention in formal design space movement algorithms. In this paper, we summarize this approach with an example of GTFS subsumption process.

title	Exploring Intended Implicate Solution
doi	https://doi.org/10.52842/conf.caadria.2009.567
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 567-576
summary	Design is an iterative exploration process that will invoke many fragmented information with continuous iteration. While fragmented, implicit information lay among these fragmented pieces has shown more potential to achieve some goals that we might skip during the decisionmaking. These potential design goals named implicit intended solution are the problem spaces we want to explore in this research. Therefore, the continuous thinking/operation process cross these fragmented design decision might show some insights for discovering implicit intended solutions. This is a two-fold problem, without exploration and its continuous iteration characteristics, these solutions might not even be found or possible found. Therefore, in this paper we have conducted a research based on visualizing these implicit intended solutions as well the exploration process for finding them.

title	CAADRIA 2009 - Between Man and Machine
doi	https://doi.org/10.52842/conf.caadria.2009
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, 795p.
summary	Digital designing takes place through processes of interaction between human designers and computers. As such, its location is the in-between, a shared realm of conversation where capabilities of both man and machine are amplified. CAADRIA 2009 addresses this conversation in terms of three perspectives that drive both research and practice in the computer-aided architectural design field: Digital design as integrating, intuitive and intelligent. CAADRIA 2009 aimed to provide a forum in which ideas pertaining to these notions can be explored, discussed and developed. l Digital design is integrative. With the diverse and fast speed of the global economy in the 21st century, the barrier between different disciplines is being overcome digitally. The integration of multiple disciplines is crucial for facing the next wave of global challenges. l Digital Design is intuitive. With advanced computational technology, how humans will cooperate with machines after the computing era will surely become the next challenge for all computational design-related researchers. Intuitive interaction or computing design is the second theme addressed in CAADRIA 2009. l Digital Design is Intelligent. With artificial intelligence, design intelligence is the third theme we would like to address this year. We wish to challenge global researchers to provide a smart and responsive environment for improving our lives and stimulating our economy in innovative ways.

title	Dynamic skin: Interacting with space: An inter-media interface between people and space
doi	https://doi.org/10.52842/conf.caadria.2012.089
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 89–98
summary	Space in its physical form provides the major architectural experience for the people inside the space. How people interact with their surrounding space dynamically is a noteworthy research topic. Architectural skin (or “skin” in this project) is the physical interface between people and their surroundings. The skin in this sense represents an inter-media that receive/sense the interactive behaviours of people and react back into space. Further, the skin needs to be mediated and reacted dynamically according to the interaction behaviours. With the case studies, the knowledge of skin design has achieved and then applied to develop three prototypes. In order to achieve the feasibility of skin design for dynamic skins, the multiple channels of input sensors are desired. Thus, a system called dynamic skin is proposed and details of process are evaluated. In order to incorporate the diverse scenario appeared in the cases and prototypes, a distributed system approach such as multi-agent system design is appealing to us. We propose a distributed dynamic skin platform that cannot only provide sufficient interaction between people and space, but also extending such space to the cloud and network.

title	Undo Reinterpreted

summary	The class of operations known as “undo” has proven to be a valuable addition to most professional work tools. In practice though, its use is frustrating: undo often undoes too much. Its essential informal semantics are that it returns the user to a prior state by recapitulating all intervening states. Why not give the user greater control over which aspects of a design to undo? An alternative is to seek to reuse prior work in any logically-coherent pattern—user input is a precious commodity. The area of generative systems provides insights in a search for alternatives to undo, in particular that prior user and system actions can be changed and reused in new contexts. We contingently introduce a concept we label as design promotions to describe system designs that demonstrate a tight coupling between interactive authorship and system-led generation, that treat past user actions as valuable intentional statements, and that treat alternative user choices as first-class objects of concern. In practice these three properties emphasize reuse. We briefly survey the current state of undo-like operations and potential candidates for implementing design promotions strategies. Through examples, we demonstrate approaches to realizing undo-like operations over specific representations, especially that of constructive solid geometry.

summary	The cyberspace upon physical space forms a new spatial structure to increase the influence on the urban fabric and the concept of space in architecture. Today, digital cities are being developed all over the world. By using a city metaphor, digital cities integrate urban information and create public spaces. How do digital cities directly connect to physical cities and become an imaginable city? Therefore, we argue that a new spatial analysis theory must be established for digital city, comparing with theories of disciplines, to find the explicitly spatial structures and relations in digital city upon physical city.

title	Exploring syntax and semantics of spatial structure - A study on Traditional Taiwanese City form in Chi’i’ng Dynasty
doi	https://doi.org/10.52842/conf.ecaade.2002.412
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 412-416
summary	Abstract. In this paper, we want to figure out the relations of complex semantics and syntax on five traditional Taiwanese cities in Chi’i’ng Dynasty by using a language approach. The issues of traditional Taiwanese central city in Chi’ing Dynasty had been interpreting by historical, social, and cultural research but had lacked the explicit construction of spatial structure on semantics-syntax. Therefore, we use a data modeling on knowledge level to describe the relationship between syntax and semantics. Through the research of Chi’ing Dynasty‘s history, we find out the spatial relations of Taiwanese traditional city to establish the functional categories of spatial structures. Then the language of semantics components and the meaning’s attributes are coded as logical statements to map the elements of syntax on architectural form, political vocabularies, spatial layout, and spatial myth. We argue that using this approach several social and spatial structures of cities can be clearly defined and understood.

title	Spatial Cognition in Digital Cities
source	International Journal of Architectural Computing vol. 1 - no. 4
summary	Today, digital cities are being developed all over the world. By using a city metaphor, digital cities integrate urban information and create public spaces. However, there are questions as to how to enter the new emerging digital cities, how humans perceive themselves in digital cities, and there are also issues of recognition of the digital city forms? This paper takes the idea of cognition in order to explore the structure of the new spatiality as cyberspace. By exploring the factors relating to human spatial cognition in physical space it is possible to interpret how humans perceive the spatial form of digital cities. By examining spatial experience in physical space, the interface of spatial cognition of interaction between digital cities and physical cities can be investigated. And by taking this approach, we propose an online prototype of a metaphor for a digital city.

summary	This paper aims to complement the discourse of bending-active systems by exploring a related design strategy, form-approximation. The authors explore the said strategy through analysing bending-active plate systems and commenting on its advantages and disadvantages based on physical prototype experiments and a self-built case study. Previous research has revealed that form-finding and form-conversion have their unique characteristics respectively. The authors demonstrate a new strategy of modelling the Miura origami pattern into a representation of bending-active plates and to convert the desired shape into a pattern-sewed bending-active plate construction through linear regression. The physical prototypes and fabrication experiments demonstrate the effectiveness of the form-approximation method and present a newly emerging strategy for the design and fabrication of bending-active systems.

title	Parametric design and modular construction of a large additive-manufactured hypar shell structure
doi	https://doi.org/https://doi.org/10.1007/s44223-023-00041-0
source	Architectural Intelligence Journal
summary	Despite recent advances in additive manufacturing technologies, challenges remain to build 3D-printed structures at the architectural scale due to the high cost of large printing equipment. To address this challenge, modular construction has demonstrated its merit by making smaller prefabricated components and using on-site assembly. This paper presents a case study of a 3D-printed hypar shell structural art using modular construction. Guided by parametric design and structural analysis, we optimized the hypar shell to form a butterfly-like shape with a hollow-out pattern. The prefabrication of modular units was completed using commercial 3D printers to catch a limited production time. The prefabricated modular unit of the hypar shell was assembled on site for the Guangzhou International Light Festival, in which the lighting effect was added through the adjustable transparency of hollow spaces within the sandwiched panels. The 3D-printed hypar shell was also disassembled and rebuilt in the UK, showcasing the adaptability and flexibility of the modular design. The resulting 3D-printed structural art not only provides unique aesthetics for the built environment but also demonstrates the possibility of building large shell structures with a low budget by reducing complex falsework.

summary	Climate change continues to have noticeable and accelerated impacts on various territories. Previously predictable and recognizable patterns used by humans and nonhumans alike are perpetually being altered, turning localized signals into noise and effectively disrupting indigenous modes of life. While the use of certain technologies such as data collection, machine learning, and automation can render these otherwise patternless information streams into intelligible content, they are generally associated as being “territorializing,” as an increase in resolution generally lends itself to control, exploitation, and colonization. Contrarily, indigenous groups with long-lasting relationships that have evolved over time have distinct ways of reading and engaging with their contexts, developing sustainable practices that, while effective, are often overlooked as being compatible with contemporary tools. This paper examines how the use of traditionally territorializing technologies can be paired with indigenous knowledge and protocols in order to operate between signal and noise, rendering perverse changes in the landscape comprehensible while also presenting their applications as a facet for sociopolitical, cultural, and ecological adaptation. A methodology defined as “decoding” and “recoding” presents four distinct case studies in the Arctic, addressing various scales and targets with the aim of disrupting current trends in order to grant and/or retain autonomy through what can be read as a form of preservation via augmented adaptation.
