title	(Learning from Experience)? Promises, Problems and Side-effects of Case-Based Reasoning in Architectural Design
source	International Journal of Architectural Computing vol. 1 - no. 1
summary	Learning from experience is the essence of Case-Based Reasoning (CBR). Because architects are said to learn design by experience, CBR seemed to hold great promises for their field, which inspired, in the 1990s, the development of various Case-Based Design (CBD) tools. Learning from the experience of developing and using these tools is the objective of this paper. On the one hand, the original expectations seem far from being accomplished today. Reasons for this limited success can be found at three different levels: the cognitive model underlying CBR, the implementation of this model into concrete CBD tools, and the context in which these tools are to be used. On the other hand, CBR research seems to have caused some interesting side effects, such as an increased interest in creativity and copyright, and a re-discovery of the key role that cases play in architectural design.

title	3D Concrete Printing in a Circular Economy: What We Can Learn From a 3DCP Slab Designed for Dissassembly
doi	https://doi.org/10.52842/conf.caadria.2024.3.271
source	Nicole Gardner, Christiane M. Herr, Likai Wang, Hirano Toshiki, Sumbul Ahmad Khan (eds.), ACCELERATED DESIGN - Proceedings of the 29th CAADRIA Conference, Singapore, 20-26 April 2024, Volume 3, pp. 271–280
summary	This paper investigates how 3D Concrete Printing (3DCP), through the lens of the circular economy and design for disassembly (DfD), could help transition the construction industry to more environmentally sustainable building practices. Through presentation and analysis of a case study design of a 3DCP hybrid slab, we propose how DfD principles can influence the design and construction process of 3DCP architectural elements by looking beyond material optimization and efficiency, to also include circular considerations. The analysis of a case study design finds that it is possible to incorporate DfD principles into 3DCP elements, while still achieving a reduction in overall embodied carbon relative to conventional constructions. Initial experiments on printed connections highlight that further research is required to refine jointing strategies between printed and non-printed elements. This gap is also identified in the tools available for circularity analysis, where it is found that quantitative measures for material circularity needs to be linked to measures for element circularity and disassembly.

summary	As part of a nationally funded project, we have developed and used “games” as studentcentred teaching resources to enrich the capacity for design in beginning students in architecture, landscape architecture and urban design. Students are encouraged to learn inter-actively in a milieu characterised by self-directed play in a low-risk computermodelling environment. Recently thirteen upper year design students, six from Adelaide University (Adelaide, South Australia, Australia), five from Deakin University (Geelong, Victoria, Australia), and two from Victoria University, (Wellington, New Zealand) were commissioned over a ten-week period of the 2000-2001 Australian summer to construct a new series of games. This paper discusses the process behind constructing these games. This paper discusses six topical areas: – what is a game; – specific goals of the summer games; – the structure of a game; – the game-making process; – key findings from the production unit; and – future directions.

title	The knowledge based representation and manipulation of geometry
source	Carnegie Mellon University
summary	An approach to the integration of geometric information in knowledge based systems is described as an architecture for geometric reasoning. The general requirements for this integration arise from the need for rich geometry representations in engineering domains and the conflicting demands of current geometric modelling and knowledge based systems. Four concepts are used as a basis: (1) Classes of spatial sets, which act by inheritance as a means for incremental definition by specialization, (2) Features, which denote evaluated portions of a geometric model, (3) Abstractions, which provide partial representations of geometric objects, and (4) Constraints through which spatial relationships are expressed. These four concepts combine in a synergistic manner to define the complete architecture. A prototype implementation of the architecture, built using object oriented programming techniques and a boundary based solid modeller, has been achieved and demonstrated through examples in the domains of robot task planning and automotive parts design.

summary	Today, everything is entertainment: the free time, the leisure and the mediatic and hypermediatic consumption. The incursion in the era of the service and the information, has given foot to the configuration of cultural industries whose market is centered in symbolic consumption and the mediation carried out by the intercultural hybridation derived from the capitalist tendency to expand the market of intangible goods. This symbolic market has given to origin the birth of certain tendencies and generations that are transforming, in a radical way, the mass media.

title	Sanitary Sanity: Evaluating Privacy Preserving Machine Learning Methods for Post-occupancy Evaluation
doi	https://doi.org/10.52842/conf.caadria.2020.2.697
source	D. Holzer, W. Nakapan, A. Globa, I. Koh (eds.), RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th CAADRIA Conference - Volume 2, Chulalongkorn University, Bangkok, Thailand, 5-6 August 2020, pp. 697-706
summary	Traditional post-occupancy evaluation (POE) of building performance has typically privileged physical building attributes over human behavioural data. This is due to a lack of capability and is especially the case for private spaces such as Sanitary Facilities (SFs). A privacy-preserving sensor-based system using Machine Learning (ML) was previously developed, however it was limited to basic body position classification. Yet, SF usage behaviour can be significantly more complex. This research accordingly builds on the aforementioned work to expand behavioural classifications using a sensor-based ML system. Specifically, the case study uses a GridEYE thermal sensor array, which is trained on a cubicle location within a workplace SF. A variety of ML algorithms are then evaluated on their behaviour-classifying ability. A detailed analysis of behaviour-classification performance is then provided. A system with greater fidelity is thus demonstrated, albeit hampered by imprecise behaviour definitions. Regardless, this contributes to the capability of the broader field of research that is investigating Evidence Based Design (EBD) by extending the ability to examine human behaviour, especially in private spaces. This further contributes to the growing body of work surrounding SF provision.

source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 557- 571
summary	Mobile devices have become widely used in outdoors on-the-move applications. Our research aims at developing a system which allows users to visualize the virtual buildings, streets, historic sites, landscapes or cityscapes (in the past or future) which are rendered seamlessly with the current actual scene captured by the camera (called Augmented Reality), and interactively exploring the virtual scene in real-time while the user is moving. We use the camera PDA, the GPS receiver and the gyroscope to track the mobile device’s position and orientation for virtual scene rendering. This article documents the issues regarding accurate alignment, tracking, errors and limitations with mobile devices and presents our solutions generated so far for the research in progress.

title	VEGA : A Geometric Modelling System
source	11 p. : ill. December, 1983. DRC- 48-04-83. includes bibliography
summary	VEGA is an interactive geometric modelling system which has been developed at Carnegie-mellon University primarily for education in architecture and the arts. Its educational use is twofold: first as a medium for description and manipulation of form to aid in creative work and second as a base package of procedures that may be used by advanced architecture students in the creation of specialized modelling packages. VEGA is written in PASCAL. There are versions of VEGA currently running on VAX 11/780 computer under the UNIX and VMS operating systems. VEGA has been designed to run on a stand-alone personal computer. Currently VEGA is being converted to run on Sun Microsystems and PERQ machines. VEGA is used in the undergraduate curriculum of the School of Architecture at Carnegie-Mellon University. Its primary use to date has been as a means to introduce geometric modelling to architecture students who have minimal computer experience. VEGA may be viewed as a complete geometric modelling package or as a programming aid for development of special purpose geometric modelling programs. To date, one such specialized system, a robot arm design package, has been created as a student project. The development of the VEGA system is continuing. Current areas of interest include the development of more powerful geometric operations on polyhedra, parametric shapes and assemblies, instancing of sub- assemblies, user definition of primitive shapes and an interactive macro language for the manipulation of form

summary	During the current pandemic situation, in 2020/2021, there has been an increased need for easier remote access to cultural and heritage sites, especially on users’ smartphones and personal devices. The exhibition from the 40 years anniversary of the Cultural and Scientific Divulgation Center (CDCC) of the University of Sao Paulo (USP) was selected in order to accomplish the fundamental objectives of this study. The transition of its contents to digital media was enabled by three main technologies: 360° panoramic images, used broadly in the virtual tour; close-range photogrammetry for the creation of 3D models of objects, such as the bust of Dante Alighieri; and informative GIFs of the Transparent Woman of Dresden. As a result of the methodology proposed, this paper introduces a link with the virtual tour developed, presenting an important resource to spread a multidisciplinary knowledge about this meaningful built heritage of Sao Carlos (SP).

summary	Geometric reasoning, the integration of geometric representation and inference in advanced computer systems, is presented as an issue at the forefront of research in construction automation. The unique demands that construction automation poses on such reasoning are discussed. An architecture that provides a structure for geometric reasoning is presented and results from a prototype implementation are shown. A project to develop geometric reasoning in the construction domain of panelized building systems is introduced. Within this project, two exemplary applications, structural/architectural design and construction sequence planning, each supported by the same geometric reasoning facility, are being demonstrated

title	VEGA : A Geometric Modelling System
source	11 p. : ill. Engineering Design Research Center, CMU, April 1986. DRC-48-03-87. includes bibliography
summary	VEGA is a program which models rigid solid objects in three dimensions. Specifically, its domain is assemblies of planar faced polyhedra. VEGA supports a variety of operations to create, modify, query and delete these assemblies. VEGA is intended to serve two purposes: that of a new medium of representation for the design process; and of a programming package to support geometric applications in a wide variety of domains. Here the author addresses primarily the first of these purposes, that of a new medium for design. Designers of physical objects use an external medium, traditionally paper or physical models, not only to record their work, but to provide information which assists in the understanding of implications of design decisions. Designers proceed by performing operations, which reflect internal design decisions, on this external medium. The operations used in design are generally reflective of these physical media. For example, models built of clay tend to be formed by a subtractive processes, whereas models built of wood tend to be additive in nature. Designers who use drawings as their medium still tend to use operations which reflect operations on physical models. Computers provide the fascinating potential to provide a much wider variety of operations at a much greater speed than is available with the traditional means of representation. In addition, a computer based representation can provide quantitative information not easily accessible from traditional forms. This opens the potential for the inclusion of formal means of evaluation in the design process; something which is generally almost absent in traditional design teaching. A computer program which effectively and 'naturally' models physical objects and operations on them would be a valuable assistance to both the teaching and practice design. VEGA has been designed with these objectives in mind. VEGA represents physical objects with a scheme known as boundary representation and provides a wide variety of operations on these objects. VEGA also provides means to associate other, non-geometric, information with the objects it represents. VEGA is implemented under the ANDREW system. It communicates to ANDREW through a graphics package, also developed by the author's group. VEGA is intended to serve as a medium for future studio courses in the Architecture, Industrial Design and Arts education

summary	The concrete industry's significant CO2 emissions and material usage have driven a shift towards sustainable construction, with a renewed focus on using local materials like soil, now made viable for modern construction through advancements in robotic fabrication. A key challenge with local soil is enhancing its strength for construction. The Microbially Induced Calcium Carbonate Precipitation method (MICP), which harnesses bacteria to harden soil, has emerged as a solution. Typically, MICP relies on exogenous bacteria cultivated in controlled environments, a resource-intensive process which is often challenging to apply in natural soil conditions. This paper proposes MICP through biostimulation of locally sourced soil bacteria, simplifying the process and allowing for on-site applications. This study explores the potential of MICP by stimulation in construction, utilizing advanced robotic fabrication techniques. We aim to reduce the environmental footprint of traditional concrete methods and minimize waste while increasing efficiency and precision using local soil by employing robotic fabrication techniques. Our findings are based on strength, mechanical, and performance tests, as well as experiments in formative and additive manufacturing of domes, using a custom robotic 3D printing extruder in a lab setup. These experiments confirm the feasibility of using local soil for sustainable construction. The results encourage further research to scale up the manufacturing process and enhance the material's structural strength. This research bridges the gap between traditional local material usage and modern construction technologies, offering a sustainable pathway for the construction industry.

summary	The Ocean Pavilion, located in Seattle, Washington (Figure 1), represents a contempo- rary case study of computation’s impact on effective communication and delivery of built architecture, and how these tools are questioning the habits of traditional architectural practice. A byproduct of a decade of applied research, the Ocean Pavilion illustrates a wide range of methods in which computational investigations have expanded the ability and capacity of the designers to effectively engage with consultants, contractors, and tradespeople, when compared to industry standards.Through the lens of four distinct design elements, this paper highlights moments of innovation, where computational tools and interoperability streamlined delivery of complex forms, proposed unconventional construction techniques, and enabled self-performed fabrication. With the Coral Canyon, a highly complex aquatic habitat located within the Ocean Pavilion, it navigates structural demands, rockwork and exhibit criteria, and advanced means and methods, in delivering a highly calibrated parametric model that becomes the single source of truth. Lessons learned there informed documentation for the exterior wood rainscreen, where tradi- tional architectural drawings proved inadequate in accurately communicating design intent. A third element internalizes the comprehensive design process, with the architect team self-performing fabrication. Lastly, the art soffit imbues the traditional crafts of an Indigenous Artist with computational know-how of the design team. Although differing in execution, underlying motives of collaboration and digital dissemination of knowledge are consistent throughout, offering a compelling story of computation’s impact on the Ocean Pavilion.

source	Computer Aided Design, vol.10, n.3, may 1978, pp. 161-166
summary	The paper sets forth a theory to explain how dimensions and views combine to specify the shape of a mechanical component. It provides a method to determine whether a component is under, over, or exactly defined by a given dimensioning scheme. Measures for assessing the quality of a scheme are proposed. A solution is offered to a problem of tolerancing: given a toleranced dimensioning scheme, find the resulting tolerances between undimensioned parts of a component.

summary	The purpose of this paper is to describe a comprehensive approach to representing and machining complex surface shapes in an APT programming system. The APT (Automatically Programmed Tools) user language was extended to permit the definition of a hierarchy of curves and surfaces. Much of the logic has been implemented using matrix canonical forms which are closed under the full family of projective transformations, permitting family of parts storage and retrieval and part compensation. The area of numerical control machining was addressed, but the solutions for tool positioning were only partially successful due to the complexity of the algorithmic problem. This paper first outlines some of the mathematical methods adopted and then illustrates how these have been implemented with an APT part programming example
