title	The Decisions of Facility Adaption
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Obsolescence in buildings is driven today by functional, locational and financial factors rather than by physical deterioration alone. As a result, it is no longer reasonable to expect that new building stock will remain within its originally designed class of use throughout its effective life. It is also optimistic to assume that 'change of use' adaptions, once made, will not be subject to further changes in due course. In these circumstances, the conventional notion of designing for a particular 'building type' must be questioned. The paper will describe current research into the adaptability potential of buildings, particularly the development of decision protocols to evaluate options for the adaption of vacant building stock to different uses. Speculative suggestions will be advanced concerning the probable impact of the research and on urban planning and building design.

summary	Form, process and material tend to be considered as independent or separated entities in modern design theory. This research explores the integration of parametric design with a paste-based 3D printing process. This integration intends to enable creative and holistic design inspired by nature. For that purpose, the research simultaneously develops, in a feedback loop, parametric modelling with the development of a machine to produce the shape in past-like material. The research develops a customized paste extruder to integrate the design algorithms and the machining processes. The authors test the methodology in a DIY, hands-on, empiric design integrating digital manufacture and handcraft craft, developing a customized parametric clay component, baked and glazed at a 1:1 scale for a future pavilion.

summary	This communication informs about the development of a low-cost clay extrusion mechanism, adapted to a 3d printer, which will be used to support the study and practice of architecture in the context of a research laboratory. We believe that this research is a contribution to the 3D printing community and architectural academic environment. We understand that this project makes a valuable contribution to the academic environment by promoting the production of knowledge in the “do it yourself” way by allowing the acquisition of “know how” in a procedural way. There is an effort in making our extruder mechanism replicable by whoever is interested in understanding how the system works.

title	Boundaries, Interdependence, and Coordination in ConstructionNetwork Organizations
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Of the profileration of new business paradigms in recent years, one of the primary foci has been building closer relationships between firms in the value adding chain. Lean production, which encompasses J1T, supply-chain management, and TQM/continuous improvement, has provided an important paradigm for reorganization of business practices and is in the process of revolutioni-zing western mass production industries, particularly the automotive industry. While lean production is attractive, it is not appropriate for all industries or production requirements. Lean production works best within a relatively stable production volume and stable range of products. "Mass customization" has proven difficult for accomplished lean producers such as Toyota, and requires a different set of organizational disciplines than those used in lean production. For example, in the lean production paradigm, relationships with suppliers are long-standing and steady, while in a mass customization paradigm, relationships with and between long-term suppliers will vary over time, and new suppliers will enter and leave the organization in a transient fashion. The organization form appropriate to mass customization is the network organization (also known as the virtual corporation in the popular business press), of which construction project organization is an instance, At the project level, we examine construction organization in the context of network organization theory. In particular, we examine boundaries between firms to highlight problems of coordination in a multi-firm environment, and the interdependencies that arise due to coordination needs. We provide a conceptual framework to describe these aspects of construction network organization, and discuss ways that different construction firms are dealing with coordination and boundary problems by rethinking contractual relationships and building closer ties with other firms in the network.

title	Data-Flow Algorithms for Parallel Matrix Computations
source	Communications of the ACM August, 1985. vol. 28: pp. 840-853. includes bibliography.
summary	In this article the authors develop some algorithms and tools for solving matrix problems on parallel processing computers. Operations are synchronized through data-flow alone, which makes global synchronization unnecessary and enables the algorithms to be implemented on machines with very simple operating systems and communication protocols. As examples, an algorithm that forms the main modules for solving Liapounov matrix equations is presented. The authors compare this approach to wave front array processors and systolic arrays, and note its advantages in handling missized problems, in evaluating variations of algorithms or architectures, in moving algorithms from system to system, and in debugging parallel algorithms on sequential machines

title	Neural Network Simulation as a Computer- Aided design Tool For Predicting Wayfinding Performance
source	New York: John Wiley & Sons, 1992. pp. 347-366 : ill. includes bibliography
summary	Complex public facilities such as libraries, hospitals, and governmental buildings often present problems to users who must find their way through them. Research shows that difficulty in wayfinding has costs in terms of time, money, public safety, and stress that results from being lost. While a wide range of architectural research supports the notion that ease of wayfinding should be a criterion for good design, architects have no method for evaluating how well their building designs will support the wayfinding task. People store and retrieve information about the layout of the built environment in a knowledge representation known as the cognitive map. People depend on the information stored in the cognitive map to find their way through buildings. Although there are numerous simulations of the cognitive map, the mechanisms of these models are not constrained by what is known about the neurophysiology of the brain. Rather, these models incorporate search mechanisms that act on semantically encoded information about the environment. In this paper the author describes the evaluation and application of an artificial neural network simulation of the cognitive map as a means of predicting wayfinding behavior in buildings. This simulation is called NAPS-PC (Network Activity Processing Simulator--PC version). This physiologically plausible model represents knowledge about the layout of the environment through a network of inter-connected processing elements. The performance of NAPS-PC was evaluated against actual human wayfinding performance. The study found that the simulation generated behavior that matched the performance of human participants. After the validation, NAPS-PC was modified so that it could read environmental information directly from AutoCAD (a popular micro-computer-based CAD software package) drawing files, and perform 'wayfinding' tasks based on that environmental information. This prototype tool, called AutoNet, is conceptualized as a means of allowing designers to predict the wayfinding performance of users in a building before it is actually built

title	A New Linear Algorithm for Intersecting Convex Polygons
source	Computer Graphics and Image Processing. 1982. vol. 19: pp. 384-391 : ill. includes a short bibliography
summary	An algorithm is presented that computes the intersection of two convex polygons in linear time. The algorithm is fundamentally different from the only known linear algorithms for this problem, due to Shamos and to Hoey. These algorithms depend on a division of the plane into either angular sectors (Shamos) or parallel slabs (Hoey), and are mildly complex. The authors' algorithm searches for the intersection points of the polygons by advancing a single pointer around each polygon, and is very easy to program

title	VIRTUAL ENVIRONMENTS FOR THE EVALUATION OF HUMAN PERFORMANCE: Towards Virtual Occupancy Evaluation in Designed Environments (VOE)
doi	https://doi.org/10.52842/conf.caadria.2006.x.j9t
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 521-528
summary	Analyzing and evaluating designs for modifications to suit the requirements of human performance is typically performed only after the architectural spaces and structures have been built and used, a process that is known as retrofit or post-occupancy evaluation. For people with disabilities, there is a special need to overcome this problem by evaluating the suitability of their home environments before the construction phase. Our work introduces a new methodology in which virtual reality (VR) is used for virtual pre-occupancy environmental evaluation (VOE). Our study demonstrates the potential of the VOE concept by developing an interactive living environments model to evaluate human performance before the construction phase. This paper presents an interactive virtual environment, ‘HabiTest’, as well as the initial results of a usability evaluation of this interactive environment.

summary	People only move a limited number of times during their lifetime. Factors such as high financial costs, local social networks, emotional bounds, etc. make that people typically postpone this decision as long as possible, up to the point where the benefit of alternative housing outperforms all these factors. Then things generally have to go fast. This combination of time-pressure, high costs and lack in experience turn residential search and location choice into a complex decision process. This paper presents a model developed to grasp some of this complexity. Households are approached as autonomous decision-makers continuously evaluating whether to search for information, to visit houses for inspection, to start negotiating with the owner of a house for sale or to do nothing and stay in the current house. Households make these evaluations on the basis of beliefs regarding their environment and update these beliefs each time they collect new information on this environment.

title	Am I? Architecture of Ambient Intelligence
doi	https://doi.org/10.52842/conf.acadia.2007.158
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 158-163
summary	In its purest state, Ambient Intelligence is smart computing whose presence is not apparent to the human senses except in response and actions. The original intentions and origins of Ambient Intelligence began with the need for more efficient and unobtrusive management of our everyday activities. Synonymous with ubiquitous computing, Ambient Intelligence, or AmI, consists of: UbiComp: the integration of microchips and computers into everyday objects; UbiComm: the ability of these objects to communicate with each other and the user; and Intelligent User Interface which allows inhabitants of the environment to interact with the system with human gestures (Riva 2005). Put together, these components are basically personifi ed computers. The key factor in Ambient Intelligent communities is that the microscopic computers are aware of their surroundings and their purpose just as human beings are. With the ability to self-program and react to new software, they eliminate the need for humans to program them, decreasing maintenance and programming time. These concepts and technologies raise important questions. What happens when the system disappears? Are we ready as a society to see a certain degree of power taken away from us by anticipatory computers? This short paper will provide an overview of AmI and why it is important for architects to embrace, explore, and engage this emerging technology.

summary	If the design of environments and experiences has become a key concern for many contemporary designers and artists, then what is the medium that becomes most prevalent? Light. Although elusive (one might even say 'withdrawn') and transitory, light can be seen as both objective and subjective content that is being explored by contemporary artists, designers, and architects. , In addition, the very ephemeral quality of human experience means that light (although it is a condition which is made visible, objectified and transformed through its interactions with form and surface) is often, and strangely, disassociated from objective criteria. This paper uses two recently completed projects to outline an approach to overcoming tendency to separate the objective and subjective. It describes an approach which is positioned within contemporary theory and explored through processes, methods and outcomes. The work outlined explores how effects are theorized and instrumentalized through design processes not only as subjective or 'soft', effective, atmospheric conditions, but as affective drivers of objective or 'hard' processes.

title	Integrative Pedestrian Modelling Techniques based on Virtual Force Fields - Analysis, Generation and Evaluation in Public Open Spaces
doi	https://doi.org/10.52842/conf.ecaade.2014.1.153
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 153-163
summary	This paper demonstrates a preliminary research methodology towards an integrative digital design approach for the analysis, generation and evaluation of architectural proposals in public open spaces based on human movement behaviour performances. In order to achieve this, various computational mechanisms that involve the logic of pedestrian modelling are applied, aiming to be explored in different stages of design. The suggested models follow the idea of 'virtual force' fields, an approach initially introduced in previous work by author. Based on particle behaviour modelling, this approach examines the interaction and movement behaviour of individual entities within a system through virtual effects and specifically through attraction and repulsion forces, influencing pedestrians behaviour and hence their accelerated movement. Current paper argues that the idea of 'virtual force' fields can be used not only for pedestrian simulation but also for the analysis and generation of proposals, aiming on a holistic design development of public spaces.

title	Physical input-driven offline robotic simulation through a feedback loop process

summary	This ongoing research describes a feedback loop procedure where physical inputs are used as the medium for offline robotic simulation. The purpose is to investigate the ability of industrial robots that are currently used in manufacturing processes to work in a flexible and productive manner whilst providing a continuous feedback loop between physical inputs and fabrication artifacts. In order to achieve this, a methodology is developed that involves the use of data acquisition devices to enable the transference of information from the physical to the digital environment and then to use this data as real-time parameters to control the robot's behaviour during fabrication. The aim is to achieve active involvement of robots in the manufacturing process to address complex construction issues and to ensure accuracy, a reduction in manufacturing defects and flexibility in the materials used. This investigation is accompanied by relevant experiments to exemplify the potential of control mechanisms to be used in prototyping case studies.

source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 663-671
summary	In the research project presented in this paper we investigate the architectonic and constructive potential of additive digital fabrication in timber construction through robotic processes as well as the relation of functional requirements of an exterior wooden wall to design. Form finding through performance analysis is of great interest for architects. With advanced digital fabrication technologies at hand it is possible to produce articulate building elements. This can be exploited to analyze and transform performance criteria into architectural expression. We argue that functional requirements and formal characteristics are interdependent. To allow performance criteria drive the generative parameters of design, custom software tools need to be developed which impart physical aspects of building elements to digital design models.

summary	Architectural design education can benefit from incorporation of 4D CAD techniques into a BIM-enabled process for rapid design and assessment of alternatives. Experimental courses conducted at two universities provide evidence that graduate students possessing modest skills with BIM software can adopt 4D CAD methods and integrate them into their design process with minimal effort. The method enables student teams to gain insight into the construction issues of their designs and iteratively improve design alternatives.

This paper presents the results from a set of educational case studies for the incorporation of BIM-based daylighting simulations and analyses into the design studio. With a carefully devised studio setting and the participation of interdisciplinary consultants, the experimental case studies simulated an integrated design process based on rapid information exchange and collaborative decision making. The implemented method enables students to use BIM models and daylighting simulations as significant sources of design information for performance-based architectural design.

title	1:1 SIMULATION IN ARCHITECTURAL PRACTICE
source	Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 57-66
summary	Full-scale mock ups have a long and successful history within the architectural profession. There is consensus that future users as well as professionals are better able to make design decisions in full-scale and in real time. Full-scale analogue simulation must be implemented as part of a typical design process for the sake of our clients as well as the sake of the profession: the cost of doing anything less is enormous. Altonview believes it is possible to develop an economical, flexible and utilitarian architectural environmental system (AES) which can be used, with modifications, by all professionals. Additionally, the media needs to take an interest in the AES movement, which will change their focus from the building image to the user. American architectural schools need to increase their interest in AES as well. The AES movement can be closely linked with the zeitgeist that will define the next century as seen in further examples and references from the popular press.

summary	Architecture is a profession that requires collaboration among professionals from various fields. Despite the important nature of these interdisciplinary collaborations, architecture students rarely obtain the opportunity to learn about the work areas of other stakeholders and the practice of working together. In all sectors there is a growing need for professionals who possess in-depth knowledge in their own disciplines and also develop an understanding about other related disciplines. In a setting of a student project competition, this article examines how students from various AEC fields collaborate using BIM as a common data environment and emphasizes several considerations for implementing interdisciplinary collaborations in curriculums of architecture schools in students’ perspective.
