title	Applying Genetic Algorithms to Establish Disaster Decision Support System for Flooding Evacuation Path of Hsichih Area in Taiwan
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. 63-75
summary	Because of the special geography features and subtropics weather in Taiwan, we need to provide correct information to help people making decision when they are in disaster. So the disaster decision support system must offer proper information of evacuation path to people. This research has shown the difficulties associated with the GIS and the flooding evacuation path search through the huge searching space generated during the network analysis process. This research also presents an approach to these problems by utilizing a search process whose concept is derived from natural genetics. Genetic algorithms (GAs) have been introduced in the optimization problem solving area by Holland (1975) and Goldberg (1989) and have shown their usefulness through numerous applications. We apply GA and GIS to choice flooding evacuation path in metropolitan area in this study. We take the region of Shiji city in Taiwan for case. Firstly, we establish the node relationship of GA calculation, the level of the weight is the standard of the date that is exported by Disaster Database. Secondly, we apply GA to calculate different evacuation path in different time series. Finally, we build the model of choosing flooding evacuation path.

title	Spatial Faithful Display Groupware For Remote Design Collaboration
source	T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary	Traditional remote collaboration technologies and platforms are found restrained and cumbersome for supporting geographically dispersed design activities. Based on Single Display Groupware (SDG) (Stewart, Bederson, and Druin, 1999) and Mixed Presence Groupware (MPG) (Tang, Boyle, Greenberg, 2004), a Spatial Faithful Groupware is presented in this paper to address some issues in remote collaboration. This paper discusses some of these limitations and argues how these limitations could possibly impair efficient communication among designers.

title	A Scenario-Based Agent System for Digital City Interaction
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 693-706
doi	https://doi.org/10.52842/conf.caadria.2004.693
summary	Urban design involves coordination and communication for collecting consensus among citizens and developing the design strategy and spatial program. While these are web-based systems for representing the real world actions, there is lack of human interaction for receiving feedbacks during the process. Therefore, the purpose of this study is to introduce the agents into the participatory design process (PDP) based on scenarios. This paper has developed a webbased system prototype to demonstrate how the agent can interact with users and how the interface facilitates incremental design. We present a participatory design project in an old street to illustrate how the Scenario-Based Agent System (SBAS) model functions in a real application. Meanwhile, four issues will be discussed in regarding with building a learning interaction agent as an actor.

title	What Is Intention Structure? - Represent Invisible Information of Spatial Depicts
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 275-286
doi	https://doi.org/10.52842/conf.caadria.2004.275
summary	The significant problem of this paper is how we convey spatial information to represent concrete meaning of mental imagery. For replying the above problem, we are developing a spatial information structure called "Intention Structure". Intention structure is used to represent some spatial experience of a particular person and awareness of the aura into some spatial depicts at that physical place. The meaning of “intention” is implied into a sequential relation when a navigator moves and gazes something in a place. This sequential relation can be described into two ways of spatial representation: one is the action of human body including “moving the body” and “moving the head”; another is converting the visual information into spatial memories through the behavior of gaze, including “the sight focus” and “the snapshot glance”. Otherwise, we also consider the limitation of topology at that physical place. Based on the above ideas, we use XML technologies in Java language to represent spatial data of intention structure for the describable usages of invisible information. we implemented this idea on a project of spatial analysis with Taiwanese traditional garden, the Lin family garden in Banciao, Taipei County, Taiwan.

title	Case-Based Simulation As a Technique for Assisting Architectural Design
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 189-198
doi	https://doi.org/10.52842/conf.caadria.2004.189
summary	In this research, I propose a case-based simulation method for experimenting with a set of models aimed at analyzing the behavior of a dynamic system. Owing to the assistance of CBRWorks4 software, this idea is successfully tested and implemented on the Internet. A set of evacuation simulations, which model complex human behavior in a building in certain emergency situations, leads to some discoveries and conclusions.

summary	This research has shown the difficulties associated with the GIS and the flooding evacuation path search through the huge searching space generated during the network analysis process. This research also presents an approach to these problems by utilizing a search process whose concept is derived from natural genetics. Genetic algorithms (GAs) have been introduced in the optimization problem solving area by Holland (1975) and Goldberg (1989) and have shown their usefulness through numerous applications. We apply GA and GIS to choice flooding evacuation path in metropolitan area in this study. We take the region of Shiji city in Taiwan for case. That could be divided into four parts. First, is to set the population of GA operation. Second, is to choose crossover and mutation. Third, is to calculate the fitness function of each generation and to select the better gene arrangement. Fourth, is to reproduce, after evolution, we can establish Flooding Evacuation Path that more reflect really human action and choice when flood takes place. However we can apply GA to calculate different evacuation path in different time series. Final, we compare and establish real model of evacuation path model to choosing flooding evacuation path.

title	A 3D Information System for the Digital Preservation of Historical Architecture
source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 630-637
doi	https://doi.org/10.52842/conf.ecaade.2004.630
summary	The purpose of this study is to build 3D models for the digital preservation of Chinese architecture. A historical architecture, the main hall of the Pao-An Temple, was scanned with a long-range 3D laser scanner. This temple is 19.68 meters wide, 18.2 meters wide, and 15.7 meters high. In total, the exterior and interior were registered into 1958 scans in order to cover the main hall. Scanned point clouds were converted into 3D computer models, sections, and boundary projections. Digital models were used as references for chronological records and comparison. Scanned components included the roof ridge, wood structure, dragon column, and a hanging flower. This research, which was sponsored by the National Science Council, created a two-way construction process, integrated geometric and image data, and established a digital reservation work process. Web pages were made to display 3D color components by using a plug-in to enable browsing of large files.

title	Ivy: Bringing a Weighted-Mesh Representations to Bear on Generative Architectural Design Applications
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 140-151

summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

title	Friendly Aliens Encountered: Major Problems and Principles in Digital Design Teaching
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 419-432
doi	https://doi.org/10.52842/conf.caadria.2004.419
summary	Because of the recent opening of the Kunsthaus Graz and the later coming digital design projects, those so-called friendly aliens brought more concerns on the prospects of digital design and especially the impact on architectural education. Should we stop to teach CAAD or to reconcile ourselves to the status quo in schools? This paper proposes a more compatible and feasible “Design-Oriented CAAD teaching Class (DOCC)” to transform the function of CAAD in design studios. We surveyed various CAAD teaching pedagogies in the past and also observed the status quo in Taiwan in order to develop an analytic framework for DOCC. Those investigations help us to decide strategies and understand their constraints, when CAAD is taught as a foreign language. The teaching principle and process is introduced in the undergraduate courses at NCKU. The design cycle, in which a design methodology engaged, is divided into tree stages: prototype, transformation and adaptation. A design project is implemented to demonstrate the rationale and raise later discussion.
