title	Table-Driven Algorithms for Generating Space-Filling Curves
source	Computer Aided Design. January/ February, 1985. vol. 17: pp. 37-41 : ill. includes bibliography
summary	A simple general method for constructing space-filling curves is presented, based on the use of tables. It is shown how the use of Hilbert's curve can enhance the performance of Warnock's algorithm. A procedure is given which generates Hilbert curves or Sierpinski curves. A second procedure is given which generates Warnock's windows in Hilbert order

title	Man + Water + Fan = Freshman: Natural Process of Evaporative Cooling and the Digital Fabrication of the ASU Outdoor Dining Pavilion
doi	https://doi.org/10.52842/conf.acadia.2008.208
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 208-213
summary	To the east of Johnson City TX is the Lyndon B. Johnson’s family home. Part of the Johnson Estate2 is given over to a working farm circa 1870 that presents various aspects of domestic practice from the era. This includes a desert fridge which is a simple four-legged structure with a slightly battered profile that’s draped in calico. Its principle is simple; water from an upturned jar is drawn by osmosis down the sides of the calico where it evaporates in wind currents drawn though a “dog run” between two log cabins. Cooled air circulates within the structure and where cheese and milk are kept fresh during the summer. The desert fridge is a simple system that reaches a state of equilibrium through the natural process of evaporation. ¶ This system provides a working model for a prototype structure for an outdoor dining pavilion that was designed and constructed on the campus of Arizona State University. The desert fridge is the basis for a “biological process”3 of evaporative cooling that has been interpreted in terms a ritual of outdoor dining in arid climates. The pavilion is intended as a gathering point and a place of interaction for ASU freshmen. The long-term aim of this project is to provide a multiple of these pavilions across the campus that will be the locus of a sequence of dining events over a “dining season”4 during the fall and spring semester. ; This paper describes how the desert fridge principle has been interpreted in the program and construction of the dining pavilion. It explores a sequence of levels by which the structure, via digital production process, provides an educational narrative on sustainability. This communicative quality is portrayed by the building in direct biological terms, through tacit knowledge, perceived phenomena, lexical and mechanical systems. The paper also describes how these digital production process were used in the building’s design and fabrication. These range from an empirical prognosis of evaporative cooling effects, fluid dynamics, heat mapping and solar radiation analysis through to sheet steel laser cutting, folded plate construction and fully associative variable models of standard steel construction. The aim of the pavilion is to create an environment that presents the evaporative cooling message at a multiple of levels that will concentrate the visitor in holistic understanding of the processes imbued within the building.5

summary	This paper describes a fabrication-centric studio as one example of the combination of digital and analogue design practice. It suggests that this combination, when applied to the constraints of a finite project, overcomes “mutual exclusivity” in favor of mutual dependence. It posits this scenario as a pedagogical model for upper division undergraduate learning.

title	Simulation Models and Facility Planning
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	The paper is based on a now completed research project funded by SERC and carried out by the author and former colleagues from the University of Salford in a multi-disciplinary team comprising building maintenance experts and operational researchers. The project sought to develop a model to simulate manpower deployment in a building maintenance organisation using a single case study. Although the results of the project were limited in scope, being more concernedwith the development of the methodology to deal with such problems, the work did have useful outcomes including the development of a database which contained detailed information on the hourly deployment of labour on maintenance and facilities work over a 12 month period. The proposed paper will consider the implications of the output from both the database and the simulation model for the planning of facilities and the deployment of labour in developing and maintaining those facilities.

title	Computational Experiments with a Feature Based Stereo Algorithm
source	IEEE Trans. Pattern Anal. Machine Intell., Vol. PAMI-7, No. 1
summary	Computational models of the human stereo system' can provide insight into general information processing constraints that apply to any stereo system, either artificial or biological. In 1977, Marr and Poggio proposed one such computational model, that was characterized as matching certain feature points in difference-of-Gaussian filtered images, and using the information obtained by matching coarser resolution representations to restrict the search'space for matching finer resolution representations. An implementation of the algorithm and'its testing on a range of images was reported in 1980. Since then a number of psychophysical experiments have suggested possible refinements to the model and modifications to the algorithm. As well, recent computational experiments applying the algorithm to a variety of natural images, especially aerial photographs, have led to a number of modifications. In this article, we present a version of the Marr-Poggio-Gfimson algorithm that embodies these modifications and illustrate its performance on a series of natural images.

title	Automated Semantic SWOT Analysis for City Planning Targets: Data-driven Solar Energy Potential Evaluations for Building Plots in Singapore
doi	https://doi.org/10.52842/conf.caadria.2022.1.555
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 555-564
summary	Singapore‚s urban planning and management is cross-domain in nature and need to be assessed using multi-domain indicators ‚ such as SDGs. However, urban planning processes are often confronted with data interoperability issues. In this paper, we demonstrate how a Semantic Web Technology-based approach combined with a SWOT analysis framework can be used to develop an architecture for automated multi-domain evaluations of SDG-related planning targets. This paper describes an automated process of storing heterogeneous data in a semantic data store, deriving planning metrics and integrating a SWOT framework for the multi-domain evaluation of on-site solar energy potential across plots in Singapore. Our goal is to form the basis for a more comprehensive planning support tool that is based on a reciprocal relationship between innovations in SWT and a versatile SWOT framework. The presented approach has many potential applications beyond the presented energy potential evaluation.

title	Unlocking Urban Simulation Data with a Semantic City Planning System - Ontologically representing and integrating MATSim output data in a knowledge graph
doi	https://doi.org/10.52842/conf.ecaade.2022.2.257

summary	Simulation models generate an abundance of rich raw data that remains difficult to access for non-experts. However, such data could be unlocked and utilised with a Semantic City Planning System that improves data accessibility and transparency. This paper describes a process of ontologically representing mobility simulation output data using Semantic Web technologies and storing it in a dynamic geospatial knowledge graph. Our work presents two benefits: 1) formally representing simulation output data increases the accessibility and transparency of urban simulation models, and 2) access to under-utilised rich data unlocks novel cross-domain knowledge explorations and research possibilities. We demonstrate these benefits by means of cross-domain queries related to typical city planning questions.

summary	This article aims to assess the degree of maturity of Building Information Modeling (BIM) in an Architecture and Urbanism course, identifying points of improvement and benefits, directing actions for a potential BIM implementation. The evaluation methodology investigates about Policies, Processes and Technologies of the architectural graduation course. The collection of information was done through questionnaires applied to the teaching staff. As results, it shows that BIM maturity,s level of the Institution in this course is in the ‘Defined’ level, however there are heterogeneous performances in relation to the evaluated points. It is also noticed that this result is due to the actions of a minority of teachers, not reflecting the institutionalized maturity of the entire course. On the other hand, this result indicates that efforts towards BIM adoption will start from initiatives already underway, in an environment relatively prepared for a planned insertion.

title	Cognitive Ergonomy: A combination of many didactics resources for the Architectural Drawing teaching [Ergonomia Cognitiva: A combinação de diversos recursos didáticos no ensino do Desenho Arquitetônico]
source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 35-40
summary	This work aims to present the importance of several didactic resources combination in the Architectural Drawing teaching, following the Cognitive Ergonomics concepts. From these concepts, we revised and modified the discipline teaching methodology, altering the techniques and the used technological resources. The combination of graphic software (generic, specific, tutorial) and physical models, demonstrate that the information driven to the specific interests of students improved the results in relation to productivity and satisfaction in the accomplishment of the tasks (learning). A partial evaluation of the discipline showed an improvement in: attendance, students' understanding, interaction among them, interest and more elaborated final results.

title	To reform or not to reform? Analysis of the influence of the shape in the customization of apartment projects
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 677-685.
summary	The starting point for this research was carried out through an investigation that measured in what extent original projects proposed by the real estate market were customized, resulting in Reformed Projects. It is known that many factors can influence this customization process. This phase of the research is restricted to formal and constructive factors, aiming to analyze how these can influence the customization. The shape grammar, used as an analytical tool, showed that the shape of the original projects had little influence on the result of the reformed ones, indicating that factors of other nature may be more decisive in the customization process.

summary	This paper presents the research development for a base structural module for the Casa Nordeste project. Casa Nordeste is a compact housing experiment that will participate in the Solar Decathlon Latin America competition. It consists of a modular building that houses living, cooking, and sanitizing space. Developments presented are based on digital design and fabrication principles and processes, through algorithms that allow its customization. In this sense, discussions begin with a brief theoretical discussion about the concepts that underline the project: evolutionary housing; digital technologies that improve design and construction; open source construction and generative design systems. The paper finalizes by presenting and discussing developments of three different design aspects of the structural module: (a) geometry of the frames, (b) its modulation, and (c) fittings and joining mechanisms.

title	Generative housing: a shape grammar to design and to build social houses
source	SIGraDi 2018 [Proceedings of the 22nd Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Brazil, São Carlos 7 - 9 November 2018, pp. 331-337
summary	This paper shows the development of a system to generate customized small housing projects. The process of housing construction usually involves investment for the development of the project and for the management of the building process. In small housing, this investment is left aside for economic reasons. However, due to lack of it, the project may not be adequate and its construction can be even more costly. Aiming to contribute to this issue, this paper presents the creation of a generative design system, a shape grammar, that seeks to reinterpret the traditional design/construction process of housing.

summary	This paper explores the implications of complex geometry enabled by computational technology to architectural theory and practice. It reviews the different design paradigms engaged breaking the horizontality of the floor and ceiling or fusing them together. It argues that current advances in fluid dynamics simulations open a new frontier in the conception of the usable architectural surface, in which the architectural product is no longer a fixed object, but the interaction between a fluid, changing environment and built form. The paper presents a case study in which computational fluid dynamics are utilized to reconvert a disused breakwater into a ‘blue garden’. The morphology of the breakwater and its texture are calculated to produce the conditions amiable for supporting a varied marine ecosystem, and to shape the waves to generate aesthetically meaningful sensations. The essay discusses the technical and conceptual challenges of controlling the nonlinear behaviour of fluids. It then speculates on the theoretical ramifications of having the surface interact with exterior forces and the subject's imagination to produce an event enfolding in time.

title	Computer-Based Form Generation in Architectural Design - a Critical Review
source	International Journal of Architectural Computing vol. 7 - no. 4, 535-554
summary	The idea of using computers for form generation and evaluation in the architectural design process has been put forward already in the early days of computers. However, as opposed to computer aided drafting, the generation of form, its optimization and manufacturing has not been widely accepted and implemented by practitioners. The paper critically reviews the research and state of the practice experiments that has been done in this field and develops an argument regarding the possibilities and limitations of computer-based form generation in the architectural design process.

summary	This paper presents a case study of collaborative human-robot construction, in the form of a 10-day workshop in robotically assisted construction of curved timber surfaces. The construction process developed for the workshop shows that employing computational design in combination with industrial robots can result in a demand for various kinds of labor, with a range of skill levels: in addition to tasks requiring specialized computational design skills, the proposed construction process also leads to simplification of construction tasks, by eliminating the need to measure on-site.

summary	This paper introduces metrics to evaluate stair geometry and shows how these metrics can be used to develop versatile computational stair design tools for the design of smooth stairs. The proposed stair smoothness metrics are based on the angles between tread lines, the angles between the walk line and tread lines, and the dimensions of tread sides. Using these metrics in combination with evolutionary algorithms results in computational methods that are highly flexible: as opposed to common software tools that generate particular classes of stairs (such as helical stairs or u-shaped stairs), this approach could be used for any stair design. The proposed methods produce results that match or surpass the smoothness of manually designed stairs and enable the implementation of features that are not available in other design tools, such as obstacle avoidance. Applications of the proposed method are shown for both freestanding stairs and stairs with a predefined footprint.

source	Design and Representation [ACADIA ‘97 Conference Proceedings / ISBN 1-880250-06-3] Cincinatti, Ohio (USA) 3-5 October 1997, pp. 243-248
summary	A good piece of architecture contains many levels of interrelated complexity. Understanding these levels and their interrelationship is critical to the understanding of a building to both architects and non-architects alike. A building's form, function, structure, materials, and details all relate to and impact one another. By selectively dissecting and taking apart buildings through their representations, one can carefully examine and understand the interrelationship of these building components. With the recent introduction of computer graphics, much attention has been given to the representation of architecture. Floor plans and elevations have remained relatively unchanged, while digital animation and photorealistic renderings have become exciting new means of representation. A problem with the majority of this work and especially photorealistic rendering is that it represents the building as a image and concentrates on how a building looks as opposed to how it works. Often times this "look" is artificial, expressing the incapacity of programs (or their users) to represent the complexities of materials, lighting, and perspective. By using digital representation in a descriptive, less realistic way, one can explore the rich complexities and interrelationships of architecture. Instead of representing architecture as a finished product, it is possible to represent the ideas and concepts of the project.
