title Assessment of the Impact of Digital-Manual Media Types on the Basic Design Capabilities of Architects: A Proposed Framework and Directive Measures
source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 275-276
summary The research attempts to defi ne and classify the design capabilities of architects into a basic framework. This defi nition will be useful in understanding and determining the types and nature of impact introduced by digital and manual media used during architecturaldesign process. The research consists of three parts. The First part reviews the main stages, tasks and activities of the architectural design process. The second part builds the proposed framework of design capabilities relating them to the specifi c tasks and activities conductedby the architect along the design process. The third part proposes some useful measures as to how to make use of the proposed framework in assessing the impact of media on the design capabilities of architects.

title Convex- and Solid-Void Models for Analysis and Classification of Public Spaces
source Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 253–262
summary In this paper a semiautomated morphological classification of urban space is addressed systematically by sorting through the volumetric shapes of public spaces represented as 3-dimensional convex and solid voids. The motivation of this approach comes from a frequent criticism of space syntax methods for lacking information on how buildings and terrain morphology influence the perception and use of public spaces in general and streets in particular. To solve this problem information on how façades relate with streets and especially information about the facades’ height should be considered essential to produce a richer and more accurate morphological analysis of street canyons and other open spaces. Parametric modelling of convex voids broadens the hitherto known concept of two-dimensional convex spaces considering surrounding facades’ height and topography as important inputs for volumetric representation of urban space. The method explores the analytic potentials of ‘convex voids’ and ‘solid voids’ in describing characteristics of open public spaces such as containment, openness, enclosure, and perceived enclosure, and using these metrics to analyse and classify urban open spaces.

title Artificial networks for spatial analysis
source International Journal of Architectural Computing vol. 6 - no. 1, pp. 59-78
summary This paper tests digital representation techniques which can be used by artificial neural networks in a computer-aided design (CAD) environment to analyze and classify architectural spaces. We developed two techniques for encoding volumetric data: vertex representation and feature space representation, as input for artificial neural networks. We tested how two different kinds of artificial neural networks, perceptron networks and self-organizing maps, could recognize given shapes in these representational formats. We have found that a one-layer perceptron can be used to classify shapes even when presented with input vectors composed of real numbers. These spatial representation techniques provide a method for using ANNs for architectural purposes.

summary “Frequency analysis of wood textures” presents the application of Fourier analysis to translate images of wood textures to the frequency domain. With this encoding, a lot more details can be captured by the same amount of data points than with other descriptions in the spatial domain. A small set of overlapping waves with different frequencies, magnitudes and phase angles allows to characterize the main features of the wood’s grain texture and to quantify and classify different samples. The sample’s color information is thereby enhanced with an array of direction vectors, describing the local orientation distribution.

summary Today most of the information we produce is stored digitally. We are slowly forced to leave behind us thinking about information as something stored in physical containers as books, drawings etc. We make it possible to dynamically create logical containers of information on the fly. The paper focuses on how we in the future can aggregate, classify and generalize digitally stored information in order to make it more accessible and how we can define underlying knowledge container models to support knowledge discovery and collaboration. Examples are picked from ongoing research and the outcomes are generally valid and in particular for the structural engineering field.

title Architecture and Biological Analogies
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 599-606
summary The study described in this paper evolves within the larger context of a research aimed at inquiring into analogies between architecture and nature, and more specifically between architecture and biology. Biology is a recursive source of architectural inspiration due to the tight relationship between form and function, the natural balance of forces and the corresponding geometric solutions found in living beings. Roughly, one can classify historical analogies between architecture and biology into two main categories. The first tries to mimic biological forms and the second biological processes. The specific goal of the described study is to find how new technologies can redefine and support the process of constructing such analogies. It uses as a case study a tower project designed by the architect Manuel Gausa (ACTAR, Barcelona) called Tornado Tower because of its complex shape inspired in the frozen form of a tornado. Due to the geometric irregularities of the tower, Gausa’s team had difficulties in designing it, especially because solving the structural problems required constant redrawing. This paper describes the first part of the study which primary goal was to conceive a parametric program that encoded the overall shape of the Tornado Tower. The idea was to use the program to simplify the drawing process. This required a mathematical study of spirals and helices which are at the conceptual basis of the external structure and shape of the tower. However, the program encodes not only the shape of Gausa’s tower, but also the shapes of other buildings with conceptual similarities. Such class of shapes is very recurrent in nature with different scales and with different utilities. Therefore, one can argue that the program makes a mathematical connection between a given natural class of shapes and architecture. The second part of the study will be devoted to extending the program with a genetic algorithm with the goal of guiding the generation of solutions taking into account their structural fitness. This way, the analogy with genetic procedures will be emphasized by the study of the evolution of forms and its limits of feasibility. In summary, the bionic shape analogy is made by the generation of mimetic natural forms and a genetic process analogy starts with the parametric treatment of shape based on code manipulations. At the end the program will establish an analogy between architecture and biology both terms of form and process.

title Pedestrian Thermal Comfort in Relation to Street Zones with Different Orientations – A Pilot-Study of Rotterdam
source Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 219-228
summary This paper presents the impacts of different street orientations and street zones of a typical Dutch residential area on micro-scale human thermal comfort. The spatial and temporal variation of mean radiant temperature (T mrt ) of a typical summer day in Rotterdam, The Netherlands, is simulated by using an established long- and short-wave 3D radiation fluxes model (SOLWEIG). This model calculates human radiation load and expresses this as a T mrt . Hereby we simulate and analyse the T mrt variations for three zones of a street consisting of a centre area for cars and the adjacent pedestrian zones for pedestrians and bicycles. The streets are azimuth rotated. The simulation and analysis results show various T mrt patterns of the three zones in the different orientations at different periods during daytime. We show that the spatial distribution of T mrt at street level strongly depends on street orientation and street zone. This is crucial since optimizing street configuration will directly influence the human thermal comfort in relation to street orientation and street zone. Finally we present a time adjusted framework of thermal comfort and classify the various T mrt for each zone and orientation.

source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

summary This work covers the methodological approach that is used to gather information from the wisdom of crowd, to be utilized in a machine learning process for the automatic generation of minimal apartment units. The flexibility in the synthesis process enables the generation of apartment units that seem to be random and some are unsuitable for dwelling. Thus, the synthesis process is required to classify units based on their suitability. The classification is deduced from opinions of human participants on previously generated units. As the definition of "suitability" may be subjective, this work offers a crowdsourcing method in order to reach a large number of participants, that as a whole would allow to produce an objective classification. Gaming elements have been adopted to make the crowdsourcing process more intuitive and inviting for external participants.

summary There are many words written about the motion in architecture. (Giedion, Ferstegen, Jormakka, Lynn). They try to describe, classify, separate or represent it. This work presents motion as one of the leading factors of contemporary ways of expression in architecture. It will examine different examples of architectural motion, then make a hypothesis, that one of the possible reasons of expressing movement in architecture is the usage of new generation of modern CAD/3D-animation software, like 3DStudio Max, Lightwave, Maya, Catia, Rhino, or CINEMA 4D.

title HalO [Indoor Positioning Mobile Platform]: A Data-Driven, Indoor-Positioning System With Bluetooth Low Energy Technology To Datafy Indoor Circulation And Classify Social Gathering Patterns For Assisting Post Occupancy Evaluation
source ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 284-291
summary Post-Occupancy Evaluation (POE) as an integrated field between architecture and sociology has created practical guidelines for evaluating indoor human behavior within a built environment. This research builds on recent attempts to integrate datafication and machine learning into POE practices that may one day assist Building Information Modeling (BIM) and multi-agent modeling. This research is based on two premises: 1) that the proliferation of Bluetooth Low Energy (BLE) technology allows us to collect a building user’s data cost-effectively and 2) that the growing application of machine learning algorithms allows us to process, analyze and synthesize data efficiently. This study illustrates that the mobile platform HalO can serve as a generic tool for datafication and automation of data analysis of the movement of a building user. In this research, the iOS mobile application HalO, combined with BLE beacons enable building providers (architects, developers, engineers and facility managers etc.) to collect the user’s indoor location data. Triangulation was used to pinpoint the user’s indoor positions, and k-means clustering was applied to classify users into different gathering groups. Through four research procedures—Design Intention Analysis, Data Collection, Data Storage and Data Analysis—the visualized and classified data helps building providers to better evaluate building performance, optimize building operations and improve the accuracy of simulations.

title A Knowledge-Based Approach to Using Efficiency Estimation in Program Synthesis
source 1980? pp. 457-462. includes bibliography
summary This paper describes a system for using efficiency knowledge in program synthesis. The system, called LIBRA, uses a combination of knowledge-based rules and algebraic cost estimates to compare potential program implementations. Efficiency knowledge is used to control the selection of algorithm and data structure implementations and the application of optimizing transformations. Prototypes of programming constructs and of cost estimation techniques are used to simplify the efficiency analysis process and to assist in the acquisition of efficiency knowledge associated with new coding knowledge. LIBRA has been used to guide the selection of implementations for several programs that classify, retrieve information, sort, and generate prime numbers

summary This research established classification system which contains five principles and variables to classify the types of the virtual landscape in digital games. The principles of the classification are Story, Space Shape, Space and Action Dimension, User Complexity and Interaction Level. With this classification system, our research group found the most representative types of virtual landscape in the digital game market through 1996 to 2016. Although mathematically there can be 288 types of virtual landscape, only 68 types have been used in the game market in recent twenty years. Among the 68 types, we defined 3 types of virtual landscape as the most representative types based on the growth curve and a number of cases. Those three representative types of virtual landscapes are Generating / Face / 3D-3D / Single / Partial, Providing / Chain / 3D-3D / Single / Partial and Providing / Linear / 2D-2D / Single / Partial. With the result, the researchers will be able to establish the virtual landscape design framework for the future research.

summary The lack of understanding of the character essence of avatars brings about limitations in interaction with their expressions. With the state-of-the art CAD standard and virtual reality, our approach is to explore the different paradigm of virtual architecture focusing on social interaction through avatars’ gesture expression. The method to classify context-aware expression data model and to autonomously activate it in real-time along with users’ communication is investigated. A domain of virtual office has been chosen as our study model based on our previous research. To achieve our goals, an avatar expression agent is developed based on our previous context-aware architectural simulation platform so called ‘V-PlaceSims’. The output is delivered as a Web page with an ActiveX control embedded to simulate and to evaluate through the internet. As users communicate with one another using a text box, the avatar expression agent simultaneously detects the users’ emotion by parsing the input texts to perform related gestures automatically. The result reveals a new convenience way to communicate with the other users with an enhancement in automated expression.

source Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 535-544
summary This paper aims to apply the clustering analysis algorithm to analyze and classify the pattern of spatial topology of floor plans within a case library named “Open Case Study (OCS)”. Based on the results of classifications, this paper proposes a visual interface named “Topology Pattern Mining (TPM)” to present and rank searching results in response to user’s queries. The purpose of TPM is to extend the capacity of OCS for representing implicit knowledge of spatial topology. TPM can retrieve and classify design patterns of spatial topology, and thereby helps users to learn the design knowledge within relevant cases.

summary Urban design always requires the processing of large amounts of data from multi-disciplinary sources during the decision-making stages. However, unfamiliar multi-disciplinary data sets can only lead to confusion and uncertainty. This research proposes a data-driven approach for supporting the urban design process. A hybrid data mining method is used to cluster, classify and rank solution-instances according to geometrical properties and energy performance. An urban design case study is used to demonstrate the proposed method with respect to two performance issues: solar heat gains and natural ventilation. The result shows that the method addressing both familiar and unfamiliar data can effectively guide the designer during the design process.

title Heuristic Search and Tree Systems Inference for Structural Pattern Recognition
source Knowledge based systems. 1988. vol. 1: pp. 78-89
summary An experiment is reported that combines the use of a heuristic search and a tree systems inference technique to induce context-free relational grammars that generate patterns in the style embodied in a sample set. This is achieved by searching for concise structural representations of each pattern in a sample set and discovering regularities in their tree systems representation. The knowledge induced is represented as an accepting tree systems automation and generative grammar, and is used to classify extant patterns and generate novel ones. Examples are given to illustrate the methodology, and to lend support to the hypothesis that the style of a pattern can be partially characterized by a unique generative process

title Sistema interativo para análise das relações de afinidade entre o círculo e a elipse [Interactive system for analysis of the circle and ellipse affinity relations]
source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 258-260
summary This paper will try to establish a dialogue between the process of rational geometric construction and the intuitive process of discovering shapes. This will involve: a geometric principle that works as a geometric generation law and two interactive macros. The geometric principle is the affinity between circles and ellipses. The macros, developed in VisualLisp languagefor AutoCAD, allow the students to construct 3D abstract structures.
