title Implications of the philosophy of Ch. S. Peirce for interdisciplinary design: developments in domain theory
source Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary Subject of this paper is the establishment of a connection between categorical pragmatism, developed by Charles Sanders Peirce (1839-1914) through phenomenological analysis, and Domain Theory, developed by Thijs Bax and Henk Trum since 1977. The first is a phenomenological branch of philosophy, the second a theory of interdisciplinary design. A connection seems possible because of similarity in form (three-partitions with an anarcho-hierarchical character), the not-absolute conception of functionality and the interdisciplinary and procedural (participation based action) character of both theories.

title Modulating Natural Ventilation to Enhance Resilience Through Modifying Nozzle Profiles - Exploring Rapid Prototyping Through 3D-Printing
source T. Fukuda, W. Huang, P. Janssen, K. Crolla, S. Alhadidi (eds.), Learning, Adapting and Prototyping - Proceedings of the 23rd CAADRIA Conference - Volume 2, Tsinghua University, Beijing, China, 17-19 May 2018, pp. 185-194
summary The study aimed to develop and test an environmentally friendly, easily deployable, and affordable solution for socio-economically challenged populations of the world. 3D-printing (additive manufacturing) was used as a rapid prototyping tool to develop and test a façade system that would modulate air velocity through modifying nozzle profiles to utilize natural cross ventilation techniques in order to improve human comfort in buildings. Constrained by seasonal weather and interior partitions which block the ability to cross ventilate, buildings can be equipped to perform at reduced energy loads and improved internal human comfort by using a façade system composed of retractable nozzles developed through this empirical research. This paper outlines the various stages of development and results obtained from physically testing different profiles of nozzle-forms that would populate the façade system. In addition to optimizing nozzle profiles, the team investigated the potential of collapsible tube systems to permit precise placement of natural ventilation directed at occupants of the built space.

title Development of a Building System
source Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary The universal principle of architecture can be defined as follows: “The architectural product is the synthesis of the different man-made physical environments that are formed by locating the series of building components in different ways”. Within this context; it is necessary to determine the principle of building assembly and the assembly of ‘material components’ in order to produce the building. The material components are the elements of sub systems (such as; structural, envelope, services, partitions, circulation, and finishing systems) which form the building system of an architectural product. Every building is an integrated product. Integration defines the relations of sub systems with the whole. Therefore, it is necessary to define the sub systems and their relations in realizing the architectural product. This paper presents the analysis principles of the sub-systems, relationship between the analyzed systems and components, integration principles and possibilities of them, and the future conditions.

title A World of Data: An Animated Construction Information System as a Virtual Hypergraphic Environment
source Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 267-274
summary This paper describes research on an animated construction information system organized as a hypergraphic virtual environment. The user enters this environment to interact with the information it contains. A matrix of cubes sits as the gateway to an array of data chambers that give this information its virtual form. A mouse click on one of these cubes leads to a three-dimensional interface that is a simulation of the object to be constructed. Reflective-transparent panels surround the simulation and display two-dimensional projections of its pieces. These panels capture projections of slices through the pieces of the object represented by the simulation. Below the zero plane are slices of floor framing, foundation, excavation, utilities, and soil conditions. Above are ceilings, framing, and roofing. To the sides are finishes, wall framing, fixtures, and elevations. This immersive virtual environment extends as an array of data chambers partitioned by the suspended reflective-transparent panels. Pathways around these partitions lead to secondary chambers that contain sub-simulations of the plumbing, electrical, and HVAC systems. Design-team members access these chambers to coordinate the document's development, review progress, and make changes to the information system. The result is a WORLD of data where graphic information defines both space and time. This breaks with the notion of a construction document as an object-of-exchange and suggests a new focus for the use of computers in the design and construction process.

title The Light Buffer: A Shadow-Testing Accelerator
source IEEE Computer Graphics and Applications. September, 1986. vol. 6: pp. 6-16 : col. ill. includes bibliography
summary In one area of computer graphics, realistic image synthesis, the ultimate goal is to produce a picture indistinguishable from a photograph of a real environment. A particularly powerful technique for simulating light reflection - an important element in creating this realism - is called ray tracing. This method produces images of excellent quality, but suffers from lengthy computation time that limits its practical use. This article presents a new method to reduce shadow testing time during ray tracing. The technique involves generating light buffers, each of which partitions the environment with respect to an individual light source. These partition descriptions are then used during shadow testing to quickly determine a small subset of objects that may have to be tested for intersection. The results of timing tests illustrate the beneficial performance of these techniques. The tests compare the standard ray-tracing algorithm to light buffers of varying resolution

title Automatic Floorplan Design Using PIAF
source August, 1988. 36 p. : ill. tables
summary This paper presents PIAF (a Package for Intelligent and Algorithmic Floorplanning), developed at Sydney University Electrical Engineering (SUEE) for use in custom integrated circuit design. Floorplanning plays a crucial role in the design of custom integrated circuits. When design is approached in a top-down fashion, the function to be implemented on silicon is first decomposed in a conceptual phase into a Functional Block Diagram (FBD). This FBD has a 'blocks and buses' structure where blocks represent sub- functions and buses represent the interconnections that carry data and other information between blocks. The decomposition of the function into sub-functions is hierarchical and aims at reducing the complexity of the design problem. When the FBD is known, the floorplanning process may be performed. When this task is performed manually, the designer searches for a relative placement of the blocks and for an area and shape for each block to minimize the overall chip layout area while at the same time meeting design constraints such as design tool limitations, interconnection characteristics and technological design rules. PIAF is a knowledge-based system (KBS) that has been developed at SUEE during the last four years. It relies on a strategy that partitions the floorplanning task in a way that allows efficient use of heuristics and specialized design knowledge in the generation and pruning of the solution space. This paper presents the operation of PIAF and discusses several implementation issues including; KBS structure, knowledge representation, knowledge acquisition, current context memory design, design quality factors and explanation facility. This paper uses a running example to present the operation of each PIAF's KBS-based solving phases

summary This paper chronicles an intensive student workshop on sensponsive architecture, from the educators’ point of view, underlying the pedagogical notes on this new design approach that employs digital design tools and electronic assemblies to creatively experiment with human-computer interaction. The workshop presented the theoretical, computational and fabricating frameworks for a human-centered approach to spaces with sensponsive partitions that respond timely with sense, displaying an adaptive behavior through time. The workshop theme was further specialized to direct the design outcome toward sensponsive environments for children that can help them perceive, experience and develop a meaningful understanding of the world around them through play.

title Perfect Distribution Phenomenon and the Origin of the Spacetime Harmony
source International Conference on Generative Art
summary Perfect Distribution Phenomenon (PDP), namely one- (t=1) and t-dimensional (t>1) Ideal Ring Relationships (t-D IRR)s are cyclic sequences of integers which form perfect partitions of a finite interval [1,s] of integers. The sums of connected sub-sequences of an IRR enumerate the set of integers [1,s] exactly R-times. Example: The 1-D IRR {1,3,2,7} containing four elements (Fig.1) allows an enumeration of all numbers 1=1, 2=2, 3=3, 4=1+3, 5=3+2, 6=1+3+2, 7=7, ... 13=1+3+2+7 exactly once (R=1).

title Integrating energy consciousness in the design process
source Automation in Construction 8 (4) (1999) pp. 463-472
summary The design process for an intelligent, energy conscious building which was built, along with the design tools that were applied, is presented. The building, situated in the hot–humid climate of Rehovot, Israel, houses the laboratories and offices of the Weizmann Institute's Environmental Science and Energy Research Department. Alternative bio-climatic design options were proposed and evaluated throughout the detailed design stage. A building energy performance index (BEPI) was established for each alternative. This index reflects the total amount of energy consumption for heating, cooling, ventilating and lighting used per square meter of floor area. Thermal modeling for the different design alternatives were carried out by means of an hourly dynamic simulation model. The model solves simultaneously the heat transfer equations through all exterior walls, taking into account the thermal mass of each external wall as well as internal partitions. The model was extended to include hourly calculations of daylighting and geometrical shading coefficient of the windows, as well as automated and `smart' control strategies.

source Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 347-350
summary The purpose of this study is to present an application of an RP machine in the substantiation of architectural design concepts, using color image mapping to enhance visual details. Related visualization leads to the exploration and comprehension of shapes. Exemplification can be seen in the verification for proofing or documentation of as-built models, such as paper architecture, process modeling, furniture, partitions, and construction details. The influences on architecture reveal issues related to pedagogical exploration, interdisciplinary exploration, reality management, and visual detail and structural detail.

summary The paper investigates the management of acoustic and privacy problems in open-plan spaces through the implementation of lightweight architectural partitions developed by origami tessellations. Integrating knowledge from parametric modelling, acoustics and design for user needs, a design tool for acoustically efficient, flexible, interior partition systems is developed. The paper elaborates on three components of the design tool: form generation, acoustic performance and spatial performance. The form generation component employs parametric models of origami tessellations to generate the partition system. The acoustic performance component employs acoustic simulation and prediction to regulate the containing volume as well as the system's surface materials. The spatial performance component evaluates form and material through qualitative criteria for privacy and flexibility according to user needs.

title Comparison of Partitioning Methods for Estimating the Layout of Green Spaces

summary The urban green space positively affects the quality of the environment and urban life. To estimate the layout of urban green spaces, especially to describe the real difference of regional properties, the influenced zone of each green space should be identified firstly. The influenced zone can be used to quantitatively analyse the difference of regional environmental quality. The identification of the influenced zones of green spaces actually is a problem of space partitioning. The study compared three methods mostly used in space partitioning. The regular grid is a most common partitioning method. It is easy to use, but cannot link the grid with green space separately. Voronoi algorithm is a constructive method which partitions the urban space based on each green. Another approach is the application of gravity models, which assumed analogies between human behaviour and Newtonian gravity laws. The gravity model could calculate the probabilities of residents to choose the green space and partition the urban space. In the comparison of these three methods, we conclude that the gravity model can take more characteristics of the green space as the calculating parameters. The gravity model is a better method to estimate the layout of urban green spaces.

title Mediators in the Architecture of Future Information Systems
source IEEE Computer 25, no. 3: 38-48
summary The installation of high-speed networks using optical fiber and high bandwidth messsage forwarding gateways is changing the physical capabilities of information systems. These capabilities must be complemented with corresponding software systems advances to obtain a real benefit. Without smart software we will gain access to more data, but not improve access to the type and quality of information needed for decision making. To develop the concepts needed for future information systems we model information processing as an interaction of data and knowledge. This model provides criteria for a high-level functional partitioning. These partitions are mapped into information processing modules. The modules are assigned to nodes of the distributed information systems. A central role is assigned to modules that mediate between the users' workstations and data resources. Mediators contain the administrative and technical knowledge to create information needed for decision-making.

title A Linear Time Algorithm for Triangulating a Point-Visible Polygon
source ACM Transactions on Graphics. January, 1985. Vol. 4: pp. 60-70 : ill. includes bibliography
summary The triangulation of a point-visible (star-shaped) polygon cannot be performed trivially if its kernel does not share a vertex with the polygon. The paper presents a triangulation algorithm that exploits point-and strong edge-visibility. It is through these two properties that the authors are able to triangulate in linear time. After classifying simple polygons by visibility, the authors show that strongly edge-visible polygons can be triangulated in linear time. A point-visible polygon is transformed into a strongly edge-visible polygon by the following steps: partitioning with a ray, partially triangulating both partitions, merging the two remaining polygons, and showing that the merged polygon is a strongly edge-visible polygon
