title Thinking Graphic and Design Collaborative. Developable geometries for folded architectural compositions
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. 702-707.
summary The design, manufacturing and assembly of SSFS (Same Slope - Folded Surface) Pavilion, is presented as a collaborative design experience recently developed between two Ibero-American universities (USevilla-UNL). In this experimental research, Graphic Thought feeds on the strategic use of developable geometries like to achieve outstanding manufacturing and installation of a temporary Folded composition. The practical exercise, results in a procedural model of open applications, nonlinear, for the generation of pavilions with different solutions adapted to each particular context.

title Implicit Fabrication, Fabrication Beyond Craft: The Potential of Turing Completeness in Construction"
source ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 383-390
summary This paper addresses the limited shared vocabulary of landscape architecture and architectural design, evident in the application of terms such as “spatial design” and “spatial planning.” In their current usage, such terms emphasize the visible, terrestrial, pedestrian-perspective level, often to the absolute exclusion of a spatial, i.e., volumetric comprehension of the environment. This deficit is acutely evident in the teaching of landscape architecture and architecture and discussion of these fields’ shared ground. The dominant document type for mapping such analysis and design is the plan, or three-dimensional representations of the same, restricted to an extrusion or height map. GIS techniques in spatial design tend to be weighted toward visual, surface-based data (slope analysis, exposure, viewshed, etc.). Within this domain, our goal is to transform aspects of the intangible—the characteristics of open space itself—into a form that is legible, quantifiable, and malleable.

title Archaeological Site Reconstruction With AutoDesk's 3D Studio
source CSA Newsletter Vol 7:3 Nov 1994
summary 3D Studio is an IBM-compatible computer modeling program that enables users to create three-dimensional renderings of a variety of objects. In its ability to import a wide variety of maps and other images, 3D Studio allows for the realistic rendering of models created within AutoCAD or other 3D CAD packages. Over the past year, the Homol'ovi research program has been utilizing this software to create near photo-realistic renderings of conjectural site models. My own interests in three-dimensional computer modeling developed out of work at the site of Homol'ovi IV, a 150-room pueblo site located near Winslow, Arizona. The site was situated upon a steep 30-meter bluff with a bedrock cap. Approximately 24 rooms were located on top of the bedrock cap, with another 125 rooms situated on the slope of the butte. During the 1989 field season five structures were excavated, while a separate crew worked clearing and mapping the tops of walls. Mapping was accomplished with a Topcon EDM/theodolite station, and a standard map was created from this process. (See Fig. 3.) While the map was sufficient to show the general layout of the site, I remained unsatisfied; a 2D plan view simply did not convey the vertical dimension of the pueblo. At this point the Homol'ovi Research Program purchased a copy of AutoCAD in order to begin exploring three-dimensional mapping and modeling.

title Development of a Wheelchair Virtual
source 3rd International Conference on Disability, VR and Associated Technologies, Sardinia, (Ed. P Sharkey) ICDVRAT2000, 1-8
summary In the UK the Disability Discrimination Act 1995 aims to end discrimination against disabled people. Importantly the Act gives the disabled community new employment and access rights. Central to these rights will be an obligation for employers and organisations to provide premises which do not disadvantage disabled people. Many disabled people rely on wheelchairs for mobility. However, many buildings do not provide conditions suited to wheelchair users. This project aims to provide instrumentation allowing wheelchair navigation within virtual buildings. The provision of such instrumentation assists architects in identifying the needs of wheelchair users at the design stage. Central to this project is the need to provide a platform which can accommodate a range of wheelchair types, that will map intended wheelchair motion into a virtual world and that has the capacity to provide feedback to the user reflecting changes in floor surface characteristics and slope. The project represents a collaborative effort between architects, bioengineers and user groups and will be comprised of stages related to platform design, construction, interfacing, testing and user evaluation.

title Study on Zoning of Urban Morphology based on GIS
source Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 317-326
summary The traditional studies of urban morphology mainly focus on material aspects such as urban construction, urban environment. The writers of the paper, however, point out that the nature behind material aspects should be load capacity of urban land-use, which can be reflected through some economic and technological indexes, such as floor area ratio(FAR), building density and building height, and generally they are relative. The paper forms a new morphology zoning method after having studied the relation of the above indexes based on the digital methods of GIS. This rout of thought may have some reference value for controlling the expanse of urban land-use, optimizing the allocation of resources and urban morphology and supervising the implementation of urban planning. In the paper, the author proposed the concept of “zhubei” to describe and evaluate urban morphology. We can further analyze “zhubei” regards urban planning analysis and management, for example, the slope analysis, aspect analysis, view analysis, area and volume analysis etc. Therefore, we can describe current urban morphology and evaluate its rationality by relevant conclusions just like describing vegetation.

title Virtual Environments for Special Needs. Changing the VR Paradigm
source Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 151-159
summary The normal application of Virtual Reality is to the simulation of environments, which are in some way special - remote, hazardous or purely imaginary. This paper describes research and development work which changes the paradigm by simulating perfectly ordinary buildings for special people. Some 15% of the population have some form of physical impairment - a proportion which is likely to rise in line with an ageing population. New legislation, such as the UK Disability Discrimination Act places additional responsibility on building owners to ensure adequate access for people with an impairment and this in turn will place additional responsibility on the architect. Current methods of auditing access for new building are primitive and require the auditor to interpret plans/sections of the proposed building against a checklist of requirements specific to the special need. This paper reports on progress in the use of an immersive VR facility to simulate access to buildings for two broad classes of user: i) those with a mobility impairment; ii) those with visual impairment. In the former case, a wheelchair motion platform has been designed which allows the wheelchair user to navigate the virtual building; a brake and motor connected to the rollers on which the wheelchair sits facilitate the effects of slope and surface resistance. In the latter case, the main categories and degrees of visual impairment can be simulated allowing architects to assess the contribution of form, colour and signage to safe access.

title Automation and optimal design method of a wheeled vehicle operating over sloped weak sandy terrain
source Automation in Construction 9 (3) (2000) pp. 277-297
summary In this paper, a mathematical model of wheeled vehicle tractive or braking performance was developed and verified by experimental data. Then, various center of gravity and height of application force movement effects were analysed by simulation analysis. For a given set of vehicle dimensions and terrain wheel system constants, the simulation calculated effective tractive or braking effort and rear wheel sinkage, slip ratio or skid of a special designed wheeled robotic vehicle running over sloped weak sandy terrain for straight forward motion. For a 5.88 kN weight vehicle, the optimal eccentricity of center of gravity, the optimal application height and the maximum slope angle of terrain could be determined for rear-wheel drive (RWD), front-wheel drive (FWD), four-wheel drive (4WD) or rear-wheel brake (RWB), front-wheel brake (FWB), and four-wheel brake (4WB) travel systems.

summary A method for inferring constraints that are desirable for a given (rough) drawing and then modifying the drawing to satisfy the constraints wherever possible, is described. The method has been implemented as part of an online graphics editor running under the UNIX operating system and it has undergone modifications in response to user input. Although the framework discussed is general, the current implementation is polygon-oriented. The relations examined are: approximate equality of the slope or length of sides, collinearity of sides, and vertical and horizontal alignment of points

title A Multi-dimensional Exploration of Urban Attributes by Data Mining
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 333-350.
summary The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970’s in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity’s database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; • Can help in the design process by providing site-specific insight through deeper understanding of urban data. • Can produce results that can assist architects and urban planners at design, policy and strategy levels. • Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.

title Magnitude Estimation of Conceptual Data Dimensions for Use in Sonification
source Rice University
summary Most data exploration tools are exclusively visual, failing to exploit the advantages of the human auditory system, and excluding students and researchers with visual disabilities. Sonification uses non-speech audio to create auditory graphs, which may address some limitations of visual graphs. However, almost no research has addressed how to create optimal sonifications.Three key research questions are: (1) What is the best sound parameter to use to represent a given data type? (2) Should an increase in the sound dimension (e.g., rising frequency) represent an increase or a decrease in the data dimension? (3) How much change in the sound dimension will represent a given change in the data dimension?Experiment 1 simply asked listeners which of two sounds represented something that was hotter, faster, etc. However, participants seemed not to make cognitive assessments of the sounds. I therefore proposed magnitude estimation (ME) as an alternative, less transparent, paradigm.Experiment 2 used ME with visual stimuli (lines and filled circles), replicating previous findings for perceptual judgments (length of lines, size of circles). However, judgments of conceptual data dimensions (i.e., the temperature, pressure, or velocity a given stimulus would represent) yielded slopes different from the perceptual judgments, indicating that the type of data being represented influences value estimation.Experiment 3 found similar results with auditory stimuli differing in frequency or tempo. Estimations of what temperature, pressure, velocity, size, or number of dollars a sound represented differed, indicating that both visual and auditory displays should be scaled according to the type of data being displayed.Experiment 4 presented auditory graphs and asked which of two data descriptions the sounds represented. Data sets based on the equations determined in Experiment 3 were preferred, providing validation of those slope values. Results also supported the use of the unanimity of mapping polarities as a measure of a mapping's effectiveness.Replication with different users and sounds is required to assess the reliability of the slopes. However, ME provides an excellent way to obtain a function relating conceptual data dimensions to display dimensions, which can be used to create more effective, appropriately scaled sonifications.

title Application of Neural Networks for Landslide Susceptibility Mapping in Turkey
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 14020-2408-8, p. 3-18
summary Landslides are a major natural hazard in many areas of the world, and globally they cause hundreds of billions of dollars of damage, and hundreds of thousands of deaths and injuries each year. Landslides are the second most common natural hazard in Turkey, and the Black Sea region of that country is particularly affected. Therefore, landslide susceptibility mapping is one of the important issues for urban and rural planning in Turkey. The reliability of these maps depends mostly on the amount and quality of available data used, as well as the selection of a robust methodology. Although statistical methods generally have been implemented and used for evaluating landslide susceptibility and risk in medium scale studies, they are distribution-based and cannot handle multi-source data that are commonly collected from nature. These drawbacks are responsible for the on-going investigations into slope instability. To overcome these weaknesses, the desired technique must be able to handle multi-type data and its superiority should increase as the dimensionality and/or non-linearity of the problem increases – which is when traditional regression often fails to produce accurate approximations. Although neural networks have some problems with the creation of architectures, processing time, and the negative “black box” syndrome, they still have an advantage over traditional methods in that they can deal with the problem comprehensively and are insensitive to uncertain data and measurement errors. Therefore, it is expected that the application of neural networks will bring new perspectives to the assessment of landslide susceptibility in Turkey. In this paper, the application of neural networks for landslide susceptibility mapping will be examined and their performance as a component of spatial decision support systems will be discussed.
