title	Zooming and tunneling in Tioga: supporting navigation in multidimensional space
source	Techn. report UCE 94/48, University of California, Berkeley
summary	In [STON93] we proposed a visual programming system called Tioga. The Tioga system applies a boxes and arrows programming notation to allow nonexpert users to graphically construct database applications. Users connect database procedures using a dataflow model. Browsers are used to visualize the resulting data. This paper describes extensions to the Tioga browser protocol. These extensions allow sophisticated, flight- simulator navigation through a multidimensional data space. This design also incorporates wormholes to allow tunneling between different multidimensional spaces. Wormholes are shown to be substantial generalizations of hyperlinks in a hypertext system. These powerful mechanisms for relating data provide users with great flexibility. For example, users can create magnifying glasses that provide an enhanced view of the underlying data.

title	Splitting Set-Theoretic Solid Models into Connected Components
source	10 p. : ill. Winchester: IBM UK Scientific Center, IBM United Kingdom Laboratories Limited, June, 1989. IBM UKSC 210. includes bibliography In general, there is no way to tell how many pieces (connected components) a set-theoretic (CSG) solid model represents, except via conversion to a boundary model. Recent work on the elimination of redundant primitives has been linked with techniques for identifying connected components in quad-trees and oct-trees into a strategy to attack this problem. Some success has been achieved, and an experimental Prolog program, working in two dimensions, that finds connected components and determines the set-theoretic representation of each component, is reported, and further developments proposed.

summary	A major problem with volume modelling systems is that processing times may increase with model complexity in a worse than linear fashion. The authors have addressed this problem, for picture generation, by repeatedly dividing the space occupied by a model, and evaluating the sub-models created only when they meet a criterion of simplicity. Hidden surface elimination has been integrated with evaluation, in such a way that major portions of the model which are not visible are never evaluated. An example demonstrates a better than linear relationship between model complexity and computation time, and also shows the effect of picture complexity on the performance of the process

summary	We developed a synthetic environment design system which not only checks the design but can also create design in realtime. This is significant since there has yet been no existing tool that can accomplish such a task. Along with the development of the tool, we are currently refining the system by applying it to the China Qingdao Jiaonan City Environmental Design Project.

source	IEEE Computer. September, 1984. vol. 17: pp. 61-73 : diagrams. includes bibliography
summary	An effective tutor must deal with a fundamental problem of communication: to determine how messages are received and understood and to formulate appropriate answers. This means that a tutor, more than a speaker, must verify that both parties know what information has been covered, what is missing, and which communication might be erroneous. In this article the authors discuss how an understanding of a student can be constructed in an artificial intelligence program and how this understanding, coupled with a facility for language generation, can be used to build flexible machine tutor

doi	https://doi.org/10.52842/conf.caadria.1997.257
source	CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 257-266
summary	The role and importance of computer aided design for industrial design is growing. Computer modeling is increasingly in demand by clients because of the downstream benefits it can bring. The creation and manipulation of three dimensional form is central to an industrial designer during the design and development of new products. The paper addresses industrial design’s relationship with computer aided modeling, particularly three dimensional geometry. Design students and professionals have been observed using current computer aided design applications. Designers’ approaches and attitudes towards computer modeling have been identified. The future impact of computer aided modeling within industrial design activity and subsequent need for change, both in education and professional practice, are highlighted.

title	Material Studies for Thermal Responsive Composite Envelopes

summary	The material-based studies examine through computation and physical prototyping layered composites for thermal responsive building envelopes. Focus is placed on surveying and computing a large series of materials across four groups, for then to test these materials from factors of solar energy reception capacities, internal heating methods, heat isolation coatings and layer bonding. An oak-polyethylene structure is developed based on the first studies and further tested towards implementation as part of an adaptive envelope demonstrator, with these studies focused on fabrication and assembly methods. Results of the developed, tested and applied composite as part of an adaptive envelope shows that the environmental-material composite is strongly influenced by colour and direct solar radiation exposure. This in turn allow a material-fabrication approach to program a responsive system driven by exergy. Reinforcing the responsive reaction of the composite by internal heating does not advance the performance, as coatings are needed to maintain the heat inside the material, which adds weight and isolate the composite from the thermal environment that otherwise is intended to provide the energy for driving the responsive behaviour.

summary	The paper presents an architectural concept and design method that investigates the use of dynamic factors in evolutionary form finding processes. The architectural construct, phenotype, is based on a brick assembly and how this can be organized based upon material properties and environmental aspects selected from the factors used in the Fanger equations to determine perceived comfort. The work finds that the developed method can be applied as performance oriented driver, while at the same time allowing diversity and variation in the architectural design space.

title	Black-Box Optimisation Methods for Architectural Design

summary	Black-box optimization methods play an important role in automated design space exploration, but to-date have not been sys- tematically compared on problems from architectural design optimiza- tion. This paper presents a quantitative comparison of the three major types of black-box optimization: metaheuristics, direct search, and model-based methods. We compare the performance of one repre- sentative algorithm of each type (including a genetic algorithm) on four performance-based design problems of varying complexity and characteristics. Our results show that metaheuristics are greatly out- performed whenever evaluating tens of thousands of design candi- dates is not an option, and suggest direct search and model-based methods as viable and more efficient alternatives.

title	Surveying Fitness Landscapes with Performance Explorer - Supporting the Design of a Better Tomorrow with Interactive Visualizations
doi	https://doi.org/10.52842/conf.ecaade.2018.1.621
source	Kepczynska-Walczak, A, Bialkowski, S (eds.), Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 1, Lodz University of Technology, Lodz, Poland, 19-21 September 2018, pp. 621-630
summary	Increasing applications of parametric design and performance simulations by architectural designers present opportunities to design more resource- and energy-efficient buildings via simulation-based optimization. But Architectural Design Optimization (ADO) is less widespread that one might expect, due to, among other challenges, the problematic integration of optimization with architectural design. This problematic integration stems from a contrast between "wicked" or "co-evolving" architectural design problems and optimization problems. To mitigate the contrast between architectural and optimization problems, this paper presents Performance Explorer, an interactive, visual tool for performance-informed design space exploration (DSE). Performance-informed DSE emphasizes selection, refinement, and understanding over finding highest-performing design candidates. Performance Explorer allows interactive DSE via a visualization of a fitness landscape, with real-time feedback provided with a surrogate model. Performance Explorer is evaluated through a user test with thirty participants and emerges as more supportive and enjoyable to use than manual search and/or optimization.

summary	This paper presents Opossum, a new optimization plug-in for Grasshopper, a visual data-flow modelling software popular among architects. Opossum is the first publicly available, model-based optimization tool aimed at architectural design optimization and especially applicable to problems that involve time-intensive simulations of for example day-lighting and building energy. The paper details Opossum's design and implementation and compares its performance to four single-objective and one multi-objective solver. The test problem is time-intensive and simulation-based: optimizing a screened façade for daylight and glare. Opossum outperforms the other single-objective solvers and finds the most accurate approximation of the Pareto front.

title	A Manufacturing Hand
source	pp. 13- 23 : ill Pittsburgh, PA: Engineering Design Research Center, CMU, September, 1986. includes bibliography.
summary	In unmanned Flexible Manufacturing Cells, robots can be used for loading machines, inspection activities, and assembly operations. What kind of robotic end-effector should be built for such tasks? The human hand has evolved to be a general purpose manipulator that adapts to the richness of our daily lives but, in doing so, it is not particularly suited to manufacturing operations. Here, special tools, fixtures, and protective layers are heavily relied on. This paper describes the initial development of a hand specifically for manufacturing work. This has involved the manufacture of an instrumented wrist with an adjustable remote center of compliance, and the design of fingers for gripping. Object shapes have also been analyzed in order to provide for a stable static grip. Importantly, these studies of the physical aspects of prehension have been matched to tasks. The research has considered a range of industrial operations and specified the level of end-effector control needed. This work is leading to some design guides for robotic end-effectors which, it is hoped, will be of use to industrial designers

title	Computational Issues in Urban Design: Developing a Strategy for Solar Impact Assessment
source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 543-555
summary	A comprehensive method for identifying the impacts on solar access of large scale architectural projects still continues to be an important and controversial area in city planning and urban design. Previous research studies such as the Sun Wind and Pedestrian Comfort, a study of Toronto's Central Area, demonstrated approaches possible when dealing with solar issues related to urban design. Existing techniques for solar inventory, analysis and evaluation, while effective, are often dependent on single event analysis (shadow casting) or manual procedures that are time consuming and exceedingly complex especially when needed for day-to-day use by planners or architects involved in complex urban projects. The Centre for Landscape Research has undertaken as part of its research to develop a computational approach that would help city urban designers evaluate and represent the issues of solar access in an urban setting. This paper will outline a series of computational methods developed to utilize an existing municipal digital data base and to describe complex issues of solar access in terms of urban form and context. A technique will be described that quantitatively assesses the total solar potential of a site as compared to changes in solar access due to different urban design proposals. Two-, three- and four-dimensional representation techniques are developed to facilitate understanding of the analysis to users such as city officials, the public, developers, etc.

source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 53-57
summary	Computer-aided Architectural Design is understood in Poland as comprising all computer applications in an architectural design office. In Polish architectural practice (with a few exceptions) it is still under theoretical consideration and in an experimental phase. Therefore if we are talking about the future of CAAD in Poland we are thinking about a much more long-term future than for Western countries. However, if new economic and organizational changes initiated in Poland in the early 1980s continue, future problems and solutions in CAAD will, for us, become similar to those in Western countries.

summary	The Department of Architecture Warsaw University of Technology was the first in Poland to take part in the third edition of the international student workshop -Virtual Design Studio. This year’s subject is a competition organized by ACSA 2A Center for Cultural and Religious Studies". The design is located on Miyajima Island in the Inland Sea of Japan near Hiroshima. VDS workshops are a proposal to create a new approach to architectural designing - working in joint groups, where the participants are separated by long distances. This idea wouldn't possible without an important tool - the InterNet. The information is sent mainly by E-mail through News Servers made by groups in each country. The News Server works as electronic pinup board where every student can locate his work. The multimedia tool -HyperDoc- permits students to easily and quickly look at other students' work. VDS'95 participants are divided into international groups of 5-7 people, They use almost every method of computer presentation: photorendering, animation, scanned freehand drawings and photos. The basic tool is CAD. Students also use traditional methods of representation like models, sketches, drawings. The Virtual Design Studio is an important experience. It shows a new concept of designing: Computer Mediated Design. The necessary contact between architect and client can be realized by the computer network. The problem of distance is eliminated. Conclusions from VDS activity will permit the creation in the future of a special net of design studios, where all discussions will be accomplished by computer. All over the world the network of Infoways will bring people together.

title	Facilitating fire and smoke simulation using Building Information Modeling
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 383.
summary	CFAST is a two-zone model which simulates fire growth and smoke transport. Manually modeling a building using CFAST user interface is a time consuming and error-prone process. In addition, the limitations in CFAST structure impede data transfer between CFAST and BIM (Building Information Modeling). In this research, we identified major limitations of CFAST, proposed solutions to the limitations, and developed a system for data interchange between BIM and CFAST. This greatly facilitated fire and smoke simulation. We further developed a visualization module to visualize the simulation results to overcome the problems when using SmokeView, an application developed by NIST (National Institute of Standards and Technology). A pilot test is conducted using this system. The simulation process was done in just a few minutes. This is expected to help architects to design buildings safer from building fires, and help students in learning building safety and fire related building codes.

title	Assessing Spatial Accessibility to Public Facilities for Vulnerable People towards 15-Minute City in Hong Kong
doi	https://doi.org/10.52842/conf.caadria.2023.1.535
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 535–544
summary	Due to the COVID-19 pandemic, people started to rely more on their communities and attach great importance to the accessibility of public facilities at a hyperlocal level. The 15-Minute City concept, first put forth by Carlos Moreno in 2016, gradually gained popularity worldwide during the age of pandemics. This human-centric concept aims to build complete neighbourhoods that meet the daily needs of residents within 15 minutes by using non-motorized transport. However, few studies focus on vulnerable groups such as children and the elderly for the assessment of 15-Minute City. Therefore, this paper provides an assessment framework for spatial accessibility to public facilities for vulnerable people from the perspective of 15-Minute City. It is measured in three aspects: spatial distribution characteristics, service population ratio and number of facilities through the comparison between Sham Shui Po and Tin Shui Wai in Hong Kong. The result shows that the accessibility to public facilities needed in daily life for children in Sham Shui Po and Tin Shui Wai is relatively reasonable, while the accessibility for the elderly needs to be improved. The research can provide references for evaluating and optimizing spatial planning to promote health and well-being in Hong Kong and other cities.

summary	Efficient floor systems can reduce the carbon footprint of building industry by reducing material, thereby responding to the UN Sustainable Development Goals (SDGs). Tile vault, a kind of masonry shell structure in history, can provide inspiration for extrusion-based 3D concrete printing. In this research, an “Extrusion-to-Masoning” perspective is proposed to evaluate, analysis, and simulate 3DCP. The variable-width filaments of 3DCP can be interpreted as variable-width bricks. The staggering pattern between different layers is studied. Three concrete shells with different layer-staggering patterns are printed and quantitative structural testing experiments are carried out. Then a totally printed floor slab prototype is designed and fabricated at the basis of one of the shells.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 582-595.
summary	The urgency for an inclusive architectural design process in conceptualizing the built environment stems from the need to establish effective communication between under- represented groups and design professionals. However, various challenges hinder the development of an inclusive design process that accommodates diverse stakeholders. Individual designers or selective design teams are frequently limited by their own visions, causing them to potentially overlook alternative solutions. Moreover, stakeholders who lack professional training might struggle to articulate their expectations. The emergence of generative AI (artificial intelligence) technologies has significantly reduced the tech- nical barriers in design, and has empowered non-professionals to vividly express their ideas regarding forms and spaces. This has presented a valuable opportunity to better understand the perspectives of underrepresented groups through visual representations. Therefore, this research aims to explore the impact of image generation on the democ- ratization of the design process. Using chair design as a testing ground, we propose an evolutionary computing framework that simulates interactions among designers and participants empowered by emerging AI technologies. To investigate the potential impact of image generation, we have implemented a multiplayer design game to allow computing agents to compete in exploring 3D chair forms. Through this approach, we aim to gain insights into how image generation influences design decisions, whether it generates more diversified solutions, and what values could be introduced into the built environment.

summary	This paper proposes a physical toolkit and a flexible software framework to simplify the design and exploration of interactive systems for multiple users, devices, and applications in a smart environment. The toolkit, called Elastic-Room, was designed as an infrastructure for interaction design, in which each device is a component that works collaboratively in the smart environment. The supporting software framework includes a dynamically reconfigurable intermediary which simplify the mapping of each device and also use simple protocol to broadcast information to each device. Finally, we demonstrate the Elastic-Room architecture by providing some implemented examples, which are organized in a prototype space of ubiquitous computing full of interactive components.

title	Improvement of the horizontal directional drilling method by using an autonomous land vehicle with a radio direction finding system
source	Automation in Construction 11 (1) (2002) pp. 75-88
summary	This article discusses the improvement in the horizontal directional drilling method (HDD) by using an autonomous land vehicle (ALV) with a radio directional finding (RDF) system. The ALV with an RDF system carrying a receiver can locate a moving or static underground drill head and track it. Not limited to a pre-determined track or path, the ALV system utilizes its on board RDF system instantaneously to seek and to track a moving or static drill head. Compared to conventional systems, the system reduces the number of operators, minimizes labor costs, prevents accidents, and enhances the degree of automation.The design of the RDF system and how to locate a target are considered in this article. To overcome the difficulty in obtaining the precise dynamic model of the ALV with the RDF system, a "fuzzy logic controller" is designed to control such a system and make the system capable of tracking a target. Experimental results verify that such an RDF ALV system can track a moving or static target.
