summary	Although it is widely known that the walkability of urban street plays a vital role in promoting street quality and public health, there is still no consensus on how to measure it quantitatively and comprehensively. Recent emerging deep learning and sensor network has revealed the possibility to overcome the previous limit, thus bringing forward a research paradigm shift. Taking this advantage, this study explores a new approach for urban street walkability measurement. In the experimental study, we capture Street View Picture, traffic flow data, and environmental sensor data covering streets within Osaka University and conduct both physical and perceived walkability evaluation. The result indicates that the street walkability of the campus is significantly higher than that of municipal, and the streets close to large service facilities have better walkability, while others receive lower scores. The difference between physical and perceived walkability indicates the feasibility and limitation of the auto-calculation method.

title	The study of Urban Acoustics through Digital Processes: New approaches to developing a Methodology
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 1 - ISBN: 978-85-8039-135-0] Florianópolis, SC, Brasil 23-27 November 2015, pp. 378-383.
summary	This paper aims to discuss different possibilities and methodologies within the field of urban acoustics and the use of digital tools. As an attempt to integrate quantitative methods, such as sound mapping and noise control, with qualitative approaches, such as the soundscape studies, new strategies based on performance oriented design will be addressed. The notion of sonic effect as an important tool for integrating different perspectives will hence be discussed as a possible instrument for structuring generative design experiments. A theoretical framework and a possible design workflow are further drawn to possibly articulate future studies.

title	A Parametric Approach to the Design of Vaulted Tensegrity Networks
source	International Journal of Architectural Computing vol. 2 - no. 2
summary	Significant new research in tensegrity theory and technology encourages tensegrity’s implementation in architecture. A recently developed technology makes possible the rapid modular assembly of deployable tensegrity units, and the construction of alternate curved configurations by re-using the same modules. Although a form exploration method for tensegrity structures already exists, estimating the structure’s new geometry remains a challenge due to difficulties designers encounter in understanding and following the method’s geometric construction process. Besides, the method doesn’t address the geometry of vaulted configurations. This paper presents algorithms that link together the geometric parameters that determine the shape of tensegrity vaults by addressing different design-construction scenarios, and a software code that generates parametric models of tensegrity vaulted structures.The application of the algorithms to the morphological study of a tensegrity vaulted dome, which constituted the main feature of an entry to arecent international architectural competition, is also presented.

title	An Immersive Modular Museum-Archive Concept Model - An integration of shape grammars with virtual reality
doi	https://doi.org/10.52842/conf.ecaade.2021.2.323
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 323-332
summary	The paper presents a concept model of a modular exhibition that is designed to function as a museum in the physical environment and as an archive of architectural projects in the virtual. A design method based on shape grammars and inspired by the Bauhaus teaching, has been used to generate both the museum spaces and the archive which expands endlessly as the acquisition of architectural exhibits keeps increasing. Specifically, rules that control the geometric organization, tectonic expression and linear or radial expansion of a modular assembly of interlocking physical or virtual spaces, leading to various self-similar spatial patterns, have been developed. Several scenarios of the visitors' interaction with the exhibits and the museum's space with the use of VR and AR have been explored. In the actual museum scenario, physically present visitors can interact with the exhibits which are enriched with digital information. In the case of the archive, the Unity platform is used for the development of a virtual experience of the visitor who interacts with the expanding space and exhibits in a purely immersive manner.

title	Tensegrity Structures of Helical Shape: A Parametric Approach
doi	https://doi.org/10.52842/conf.ecaade.2009.053

summary	Tensegrity grids composed of tensegrity units that form double layer cable nets of single or double curvature can find applications in architecture as surface structures. In this paper a parametric process for the geometric configuration and representation of double layer tensegrity structures of helical shape is discussed. Departing from the geometric construction process, an algorithm that facilitates the parametric description of helical tensegrity structures has been developed. The algorithm reflects the interdependence of all parameters involved in the design of helical tensegrity structures and has been integrated into a software application that enables the automatic generation of virtual models of helical configurations in a graphic environment.

title	Spatial Diagnosis as a Means to Design Mediated Spaces
doi	https://doi.org/10.52842/conf.ecaade.2006.420
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 420-427
summary	This paper addresses the concept of spatial diagnosis as a methodology for architects to analyze and evaluate the quality of existing spaces periodically and improve them with the use of digital media. Initially the methodology researches the physical characteristics of the examined space, which are investigated both historically and empirically, as well as people’s mental imagery of it, which is examined through cognitive mapping techniques. The research findings are used as a mapping device for the application of the digital media ‘treatment.’ Selected intelligent systems form a digital, immaterial layer upon the existing spatial elements increasing the quality of space and consequently improving people’s experience in it. The goal of this project, which focuses solely on public spaces for the extent of this research, is twofold. On a design level, it proposes a way to increase the quality of space as well as its potential to communicate with people through a synergic, adaptive approach. On a research level, it seeks to bring together three diverse but not distant disciplines, those of architecture, cognitive psychology and information technology.

title	Gentrification Waves in the Inner-City of Milan - A multi agent / cellular automata model based on Smith's Rent Gap theory
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 187-201
summary	The aim of this paper is to investigate the gentrification process by applying an urban spatial model of gentrification, based on Smith's (1979; 1987; 1996) Rent Gap theory. The rich sociological literature on the topic mainly assumes gentrification to be a cultural phenomenon, namely the result of a demand pressure of the suburban middle and upper class, willing to return to the city (Ley, 1980; Lipton, 1977, May, 1996). Little attempt has been made to investigate and build a sound economic explanation on the causes of the process. The Rent Gap theory (RGT) of Neil Smith still represents an important contribution in this direction. At the heart of Smith's argument there is the assumption that gentrification takes place because capitals return to the inner city, creating opportunities for residential relocation and profit. This paper illustrates a dynamic model of Smith's theory through a multi-agent/ cellular automata system approach (Batty, 2005) developed on a Netlogo platform. A set of behavioural rules for each agent involved (homeowner, landlord, tenant and developer, and the passive 'dwelling' agent with their rent and level of decay) are formalised. The simulations show the surge of neighbouring degradation or renovation and population turn over, starting with different initial states of decay and estate rent values. Consistent with a Self Organized Criticality approach, the model shows that non linear interactions at local level may produce different configurations of the system at macro level. This paper represents a further development of a previous version of the model (Diappi, Bolchi, 2005). The model proposed here includes some more realistic factors inspired by the features of housing market dynamics in the city of Milan. It includes the shape of the potential rent according to city form and functions, the subdivision in areal submarkets according to the current rents, and their maintenance levels. The model has a more realistic visualisation of the city and its form, and is able to show the different dynamics of the emergent neighbourhoods in the last ten years in Milan.

title	The Application of Object-oriented Software Concepts in Architectural Pedagogy
doi	https://doi.org/10.52842/conf.ecaade.2000.027
source	Promise and Reality: State of the Art versus State of Practice in Computing for the Design and Planning Process [18th eCAADe Conference Proceedings / ISBN 0-9523687-6-5] Weimar (Germany) 22-24 June 2000, pp. 27-33
summary	Architecture, a complex discipline that involves many people and things and the relationships amongst them, requires a pedagogical approach by which the student, even in her first year, must be able to think "complexly" across many subjects. The object-oriented analysis and design software programming paradigm, which models complex "realities", or "models the way people understand and process reality", holds promising concepts for architectural education. It is not my intention to extract slavishly all possible concepts from object-orientation (OO) and accept them as a "recipe" for educating the architect. Indeed, one of the reasons I find OO so elegant is that it provides a strategy, a non-prescriptive framework, with which both teachers and students can explore their own architectural investigations. It also provides the possibility of a common language, offering a structure in which, for example, certain standards can be measured within departments, or with which we can negotiate compatibility across different national credit systems to facilitate and encourage cross-cultural (border) exchange.

title	PARADISE: An Intelligent CAD System architecture
source	The Int. Journal of Construction IT 1(3), pp.1-24
summary	This paper presents the architecture of an intelligent CAD system called PARADISE. The motivation is in addressing the lack in architectural computing that has to do with intelligent assistance of design at the early stages. A schema for representing and integrating design knowledge and graphical data called the Design Model (DM) is presented. Following which, work done in developing the CAD-based front end of PARADISE called the graphic subsystem (PGS) is described. The emphasis is at providing tools which facilitate the creation and manipulation of form and spaces at early design stages. We then describe the functionalities of our geometric reasoner (PGS) is described. The geometric reasoner is responsible for all reasoning between the syntax of design drawings and its related semantics. We highlight, in particular, the reasoning of implicit spaces.

source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 639-648
summary	The shape grammar meta-language creates layers of abstraction in the shape grammar formalism for the purpose of developing descriptions that can organize and sequence rule applications in a grammar, filter information in a drawing, and provide additional matching constraints based on the subshapes found. These concepts are incorporated into the formalism by expanding the rule application process into six phases; control, context, transformations, parameters, descriptors, and application. Seven meta-language descriptive conventions are developed from the six phases; rule-sets, directive, label-filters, focus, maxline, zones, and apply-mode. Examples of how the meta-language descriptions can be used to generate designs are provided.

title	SGML: a meta-language for shape grammars
source	PhD dissertation, Department of Architecture, Massachusetts Institute of Technology, Cambridge, Mass
summary	A shape grammar develops a drawing through a series of transformations by repeatedly applying if-then rules. Although the rules can be designed, in principle, to construct any type of drawing, the drawings they construct may not necessarily develop in the manner intended by the designer of the grammar. In this thesis, I introduce a shape grammar meta-language that adds power to grammars based on the shape grammar language. Using the shape grammar meta-language, the author of a grammar can: (1) explicitly determine the sequence in which a set of rules is applied; (2) restrict rule application through a filtering process; and (3) use context to guide the rule matching process, all of which provide a guided design experience for the user of the grammar. Three example grammars demonstrate the effectiveness of the meta-language. The first example is the Bilateral Grid grammar which demonstrates how the meta-language facilitates the development of grammars that offer users multiple design choices. The second grammar is the Hexagon Path grammar which demonstrates how the metalanguage is useful in contexts other than architectural design. The third and most ambitious example is the Durand grammar which embodies the floor plan design process described in Précis of the Lectures of Architecture, written by JNL Durand, an eighteenth century architectural educator. Durand's floor plan design process develops a plan through a series of transformations from grid to axis to parti to wall. The corresponding Durand grammar, which consists of 74 rules and 15 macros organized into eight stages, captures Durand's ideas and fills in gaps in Durand's description of his process. A key contribution of this thesis is the seven descriptors that constitute the meta-language. The descriptors are used in grammar rules: (1) to organize a set of rules for the user to choose from; (2) to group together a series of rules; (3) to filter information in a drawing; (4) to constrain where a rule can apply; and (5) to control how a rule is applied. The end result is a language that allows the author to create grammars that guide users by carefully controlling the design process in the manner intended by the author.

summary	John Portman's work attracts much interest, although little scholarship exists that directly engages his contribution in formal composition. Most of the discussion of Portman's architecture tends to focus on his commercial work and hotels, although a key to understanding his work is found in his personal domestic projects where he has had the freedom to explore his architectural ideas. This study focuses on his first residence, Entelechy I, to begin outlining his design principles formally. The ambition is to open up the whole question of his architectural contribution in the United States and at large.

title	Multi-Material Fabrication for Biodegradable Structures - Enabling the printing of porous mycelium composite structures
doi	https://doi.org/10.52842/conf.ecaade.2021.1.085
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 1, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 85-94
summary	Our awareness of the earth's depleting resources has directed focus towards biomaterials, which can be extracted sustainably and biodegraded after use. Current fabrication of biomaterial structures is still restricted in strength and geometry, limiting its use in construction. This paper presents a novel two-phase multi-material fabrication process to create mycelium composite structures of higher porosity and complexity with speculated improvements in strength. First, cellulose pulp inoculated with mycelium is extruded. Then, each layer is filled by a secondary supporting material. This material, in the form of a gravel- and sand-slurry, acts as an inhospitable medium steering mycelial growth, additionally improving aeration to produce stronger structures. After an intermediate growth period, the secondary material, reusable in a closed-loop production model, is removed to reveal the fully-grown mycelium structure. The paper reports on each of the three aspects: the fabrication process, material experimentation of primary and secondary substrates, as well as geometry of varying porosity and performance.

summary	This paper is a result of a research that uses the Space Syntax Theory for analysis of the city of Juiz de Fora, Brazil. After elaborating the axial map, based on data collection available by the City Hall, some analysis of the city were made using the syntactic measures: Integration HH, Mean Depth and Total Depth. The focus of the analysis was on the central area of the city, called "Central Triangle". As a result, the analyzes make it possible to identify that the initial urban center remains as the point of convergence of several urban areas of the city, consolidating itself as an area with great potential.

summary	This paper describes an implementation of the CityMetrics toolbox, in order to provide a dynamic assessment of metrics related to walkability, diversity and density in remote and low-income urban areas. The applied methodology was used in two remote neighborhoods of Juiz de Fora, which is a Brazilian city, in a case study. The objective was to identify and to evaluate a set of weaknesses in the addressed areas and to propose some improvements in the neighborhoods´ arrangements. The ultimate goal is to contribute to a better understanding of urban problems according to walkability, diversity and density, as well as to contribute to the discussion on the design and implementation of low-income real estate developments, facilitating the management of solutions in urban planning processes in this context.
