title Urbamedia - Development of an urban database of fragments of some Argentinian and Latin-American cities using digital technology
source LOCAL VALUES in a NETWORKED DESIGN WORLD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Stellingwerff, Martijn and Verbeke, Johan (Eds.), (2004) DUP Science - Delft University Press, ISBN 90-407-2507-1.
summary The proposal of "Urbamedia" is to undertake the development of 3D virtual and interactive models of historical areas of Latin-American cities. The selected zone is the "Mayo Avenue" including the "Mayo Square", an historical place of the city of Buenos Aires, Argentina; this project is financed by the National Agency of Scientific and Technological Development of Argentina and the University of Buenos Aires.We are presenting the first experimental model of the "Mayo Square" that has been developed at ABACUS, Department of Architecture & Building Aids Computer Unit, University of Strathclyde UK. combined with a system analysis of urban activities using the “Atlas.ti” CAQDAS software.This particular use of the “Atlas.ti” software is under experimental applications to this type of urban analysis procedures; allowed us the possibility to analysed a set of activities by means of graph theory as result of a series of interviews to the people working in the area. We are also looking to include historical areas of three cities: Mar del Plata, Rosario and Santa Fe (Argentina) and eventually other cities from Latin América as Rio de Janeiro and Habana.Due that ABACUS has a strong experience in city modelling plus the powerful software and hardware used there, we must develop a VRML customized menu to be adapted to our low cost PC equipment. The 3D model will be used mainly in urban design simulation procedures and the idea is to extend to other type of simulations of the environmental parameters.

title The DXI Experience. Ten Years of Design Visualization Developments in an Educational Laboratory Context
source Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 71-77
summary Design visualisation is an essential aspect of virtually every form of design enquiry. The effects of potential environmental interventions may be simulated in order to gain the types of insights, which cannot be acquired easily from two-dimensional notations. Three-dimensional representations may be generated for very different reasons. The most direct form of design imaging is traditionally for the benefit of the designer him/herself, in order to test whether the working concepts offer fitting solutions to the complex array of design conditions such as context, programme and feasibility. Alternately, images may be generated for the benefit of communication, in order to offer insights into the expected workings of a particular proposal (possibly including alternatives). This may lead to greater understanding and possibly to reaching consensus amongst different ‘actors’ involved in the design and realisation process. In many cases the results of such visualisation studies contribute to ‘bridging the gap’ between the professionals and other parties involved more indirectly in design decision-making or the appraisal of the proposals. Designers can use distinctly different methods when going about such imaging procedures. Their choices for particular techniques may depend on their familiarity or the availability of certain media devices. Being confronted with new modelling and/or visualisation instruments can stimulate the interest in fresh approaches. In this respect, the design education environment can play an important role in not only teaching ‘proven’ applications to future designers, but also in creating a platform for the active development of innovative approaches to the design visualisation practices: education as a ‘laboratory’ for new insights and potentially a ‘breeding ground’ for the extension of the designer’s instrumentation. This contribution documents the experiences gained in some ten years within an educational application, involving active use of design driven media applications. The emphasis lies on the evolvement of techniques for eye-level imaging, whereby use can be made of different types of models: physical scale models as well as digital, virtual models. Changing attitudes towards dynamic and serial vision are considered, whereby storyboard approaches on the level of integral presentation are considered. By analysing a selection of cases and their underlying approaches an indication is given of the changing attitudes and combinations of multimedia techniques, which offer opportunities to design visualisation and communication.

summary This proposal addresses the following topic of a doctoral thesis in progress: The Evolution and Development of Digitized Processes for the Research and Maintenance of Small Town Patrimonies, School and Architecture and Urban Design, University of Buenos Aires, co-directed by architects A. Montagu and R. Gutierrez. The research has been based on the town of Mercedes, Province of Buenos Aires, Argentina, symbols of Buenos Aires.s cultural heritage. At this stage, we are looking for alternative methods to support a project of patrimonial preservation that would help define future landscapes of small towns, and, at the same time, would have minimal or positive environmental impact. This analysis proposes reflexive studies of the paradigms affecting the environment and the feasibility of the project, with the intention of utilizing the concept of .ecoproject.. Therefore, the crucial assistance of specific digital systems, from which evolution is analyzed, supports and enhances the efficiency of the proposed goal. New and broad research opportunities are opening up in this field.

title 3D Digital Space and People: Extents and Limitations of Integrating Human Figures in Architectural Animation
source Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 44-49
summary It is people that make architecture alive. It is motion that captures our attention. Together they make our architectural environment believable. Besides portraying a friendly environment, digital people can portray the best reference for scale, time, location and character of an environment. Representing architecture along with human figures has always been an integral aspect of architectural representation in traditional media. As we moved from traditional representation to animated 3D digital modeling, representation of people lost its spirit. Perhaps the reason for this is that a great deal of time and energy needed to be dedicated to the development of human figures. In addition, defining movements and poses for each figure requires additional skills. The aim of this paper is to explore the options of simulating people in the context of environmental design as well as to provide simplified techniques for representations of people in 3D digital animation.

title Environment – Urban Interface within Urban Growth

summary This work presents the synthesis of a model of urban growth dedicated to accomplish simulations of urban spatial dynamics, based on integrated urban and environmental factors and promoting simultaneity among external and internal growth. The city and surrounding environment are captured and modeled in computational ambient, by application of the centrality / potential model (Krafta, 1994 and 1999), with support of graph theory, cellular automata, GIS and geocomputation. The model assumes the city as a field of opportunities for obtaining income, mediated by the space, which is composed of urban and environmental attributes, that work as attractors or as resistances for the urban growth. The space configuration and the distribution of those attributes generate tensions that differentiate qualitatively and quantitatively the space, through the centrality measure (built with the support of graphs techniques), coming to provoke growth in places with larger potential of development (built with the help of techniques of CA – cellular automata). Growths above environmental thresholds are considered problems, generated and overcome in the same process of production of the urban space. Iterations of that process offer a dynamic behaviour to the model, allowing to observe the growth process along the time. The model presents several possibilities: a) urban - natural environment integration; b) internal and external growth integration; c) variety in the scale; d) GIS integration and geocomputation; e) user interface; f) calibration; g) theoretical possibilities; and h) practical possibilities.

title Performance Based Planning for High Density Urban Habitation
source Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 515-522
summary In Hong Kong, about 22% of the total territory‘s area can be classified as built-up area and potential development area. Only 6% of this area is allocated to district and local open space for the 6.8 million populations, i.e. 2m2 per person. Sensible planning of the limited area to enhance the livability and environmental quality hence become a challenging issue for quality urban living of the mass population. However, considering the dynamic relationship of the different performance criteria in the hyper-dense urban environment, one needs to assess various environmental criteria to carry out a balanced planning. Meanwhile, effective tools to evaluate and manage the inter-relationship of these criteria, or indexes for integrated issues indication are not readily available that a reasonable planning is not always easy to achieve. In this paper, the „openness ratio“ concept is introduced for open space planning to provide an integrated index for early stage of planning and design. The new index is expected to provide a comprehensive rating system in considering the environmental performance of open area. It helps to highlight the potential problems in planning or site layout and support the integrated thinking of the four key components: visual sensitivity, urban wind, urban noise and solar heat gain. The concept has shown to be feasible on simple massing study which is applicable in the preliminary planning stage.

summary This project had as goal to investigate how an urban space can be represented, and how can we to present information that facilitated broad and interactive spatial analysis in an easy and friendly way. This target was reached trough the elaboration of a computer application that allowed urban information visualization about Salvador City. This tool let users to build thematic cartography, visualize interactive 3D models, images, etc. Project development already produced two different prototypes. First versions provide a great spatial analyze flexibility, but it interface founded in a workspace defined do not allow user to do all overlayer possible. In this case the tool was a kind of cartographic atlas. The actual version had as design presuppose, to give users more information, interactivity, power and flexibility, adopting new medias, new representation models, and presenting quantitative and qualitative information.

summary This research proposes to support the reading of physical ambiences by the development of a representational technique which compiles, in a numerical interface, two types of data: sensory and filmic. These data are recorded through the use of a portable array equipped with sensors (Potvin 1997, 2002, 2004) as well as the acquisition of Video information of the moving environment. The compilation of information is carried out through a multi-media approach, by means of a program converting the environmental data into dynamic diagrams, as well as the creation of an interactive interface allowing a possible diffusion on the Web. This technique, named APMAP/Video, makes it possible to read out simultaneously spatial and environmental diversity. It is demonstrated through surveys taken at various seasons and time of the day at the new Caisse de dépôt et de placement headquarters in Montreal which is also the corpus for a SSHRC (Social Sciences and Humanities Research Council) research grant on Environmental Adaptability in Architecture (Potvin et al. 2003-2007). This case study shows that the technique can prove of great relevance for POEs (Post Occupancy Evaluation) as well as for assistance in a new design project.

title View from the Road: Environmental Simulation for the Fractal City of Rhine Ruhr
source Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 43-47
summary Highway seems to be more an issue of traffic planning than of urban design. But the highway can be a very important factor for the modern city pattern. Highways shape the spatial form of the fractal city. The modern highway can define new cores outside and “interior edges” within the city. Seen as a planning tool, highways are the great neglected opportunity in city and regional design. The 1st Architecture Biennial, 1ab, taking place from May 2003 to July 2003 in Rotterdam, explores the creative potentials of modern highways worldwide. An international research team discovered the spatial functions of highways in modern agglomerations. This lecture will give an overview of the results of the worldwide analyses and the design projects that had been undertaken. Both authors are members of the German research team. The German team examined the A 42 running through the Ruhrgebiet, a former coal and steal area in western Germany. The Ruhr Area is converting from an industrially orientated region to an agglomeration of high technology and science. But the regional image remains the same due to the fact that the changes cannot be seen, neither physically, nor from the road. Here, the highway could be used as a catalyst supporting and structuring the spatial changes to make them more legible for the people of Rhine-Ruhr. The nature becomes the most important tool of highway design. Landscape forms a linkage between the different cities of the region. Together with the A 40 and other local highways the region becomes the most important (and largest) public space of the new Rhine-Ruhr. The highway seen as a work of urban art can be designed only from the perspective of the driving car.

title Improved Understanding of Urban Sprawl Using Neural Networks

summary It is widely accepted that the spatial pattern of settlements is a crucial factor affecting quality of life and environmental sustainability, but few recent studies have attempted to examine the phenomenon of sprawl by modelling the process rather than adopting a descriptive approach. The issue was partly addressed by models of land use and transportation which were mainly developed in the UK and US in the 1970s and 1980s, but the major advances were made in the area of modelling transportation, while very little was achieved in the area of spatial and temporal land use. Models of land use and transportation are well-established tools, based on explicit, exogenouslyformulated rules within a theoretical framework. The new approaches of artificial intelligence, and in particular, systems involving parallel processing, (Neural Networks, Cellular Automata and Multi-Agent Systems) defined by the expression “Neurocomputing”, allow problems to be approached in the reverse, bottom-up, direction by discovering rules, relationships and scenarios from a database. In this article we examine the hypothesis that territorial micro-transformations occur according to a local logic, i.e. according to use, accessibility, the presence of services and conditions of centrality, periphericity or isolation of each territorial “cell” relative to its surroundings. The prediction capabilities of different architectures of supervised Neural networks are implemented to the south Metropolitan area of Milan at two different temporal thresholds and discussed. Starting from data on land use in 1980 and 1994 and by subdividing the area into square cells on an orthogonal grid, the model produces a spatial and functional map of urbanisation in 2008. An implementation of the SOM (Self Organizing Map) processing to the Data Base allows the typologies of transformation to be identified, i.e. the classes of area which are transformed in the same way and which give rise to territorial morphologies; this is an interesting by-product of the approach.

source SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary This paper presents the development of graphics interface on GIS (Georeferenced Information System) applied to a location model. The model performs an hierarchical analysis to locate activities related to the Biodiesel production cycle, based on castor oil (Ricinus communis L.). The case study is placed in Brazilian Northeast region, and indicates properly selected counties for Biodiesel major stages: planting, crushing and oil processing. The GIS was implemented on Windows with Personal Geodatabase and Feature Class, applied to SAD 69 references, and involves a large set of administrative, economical, social, environmental and agricultural data. Both partial and final results were obtained with graphical and query methods for selecting and editing data. A fuzzy set program imports territorial offer data and exports location indicators to database. Thematic maps are used for hierarchical data organisation and to perform a Biodiesel stages zone classification, based on graphical analysis of generated data.

title A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title SPATIAL SIMULATION AND EVALUATION - NEW TOOLS IN ARCHITECTURAL AND URBAN DESIGN
source Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7, 144 p.
summary The 5th eaea Conference in Essen yielded four principal findings: • After having been limited to endoscopic picture and film renderings of analog scaled models, the european architectural endoscopy association (eaea) first bridged the gap to digital environmental simulations at this conference. It is not about a better or correct method, but a suitable method of representing the planned reality of a particular project using ways that make sense. The combination of digital and analog simulation media is a source of impetus to the user of both methods. The future belongs to the casespecific application and the numerous integration possibilities of the two different media. • In investigating the perception of pictures produced in both analog and digital form, it was ascertained that it was only after greater effort that the same level of pleasing qualities were achieved in the digital world, compared to pictures of analog scaled models. It seems that for many planning phases model-based pictures are superior to digital photos – with regards to economy, quality of representation and imaginative attributes. This last point seems to be especially important in the draft planning stages: the less sharp a picture is, the more remaining room for viewer interpretation there is. In particular, the high degree of precision characteristic of digital simulations no longer allows room for imagination in the individual viewer. • 3D environmental simulations will increasingly be incorporated with success in architecture and urban design courses at universities and colleges both here in Germany as well as abroad. The further spread of these techniques to other universities and colleges is desirable. Over and above application as a pedagogic tool, the use of these simulations by architects and city planners, private planning agencies and municipal planning administrators will also be in evidence in the future – for checking designs, for informing the involved parties, for establishing the decisions of government bodies, for marketing the project. • Also, the interactive use of endoscopic simulation facilities continually opens new fields of research – whether it be for registering subjective distance perception, whether it be for determining orientation possibilities in open spaces.

The paper then focuses as an experiment which set out to determine how the information delivered by the computer based appraisal of virtual prototypes is ordered and used by professionals in the evaluation of design alternatives. The information provided to the professionals is detailed and their self-assessment of their management and utilsation of the data is reported, together with their critique of the experience. Conclusions are drawn and future research directions proposed.

summary This paper describes the integration of machine intelligence into an immersive architectural sculpture that interacts dynamically with users and the environment. The system is conceived to function as an architectural envelope that might transfer air using a distributed array of components. The sculpture includes a large array of interconnected miniature structural and kinetic elements, each with local sensing, actuation, and machine intelligence. We demonstrate a model in which these autonomous, interconnected agents develop cooperative behaviour to maximize airflow. Agents have access to sensory data about their local environment and ‘learn’ to move air through the working of a genetic algorithm. Introducing distributed and responsive machine intelligence builds on work done on evolving embodied intelligence (Floreano et al. 2004) and architectural ‘geotextile’ sculptures by Philip Beesley and collaborators (Beesley et al. 1996-2006). The paper contributes to the general field of interactive art by demonstrating an application of machine intelligence as a design method. The objective is the development of coherent distributed kinetic building envelopes with environmental control functions. A cultural context is included, discussing dynamic paradigms in responsive architecture.

title Integrated Planning and Decision-making Processes with 3D-environmental Simulation – The Ruhrallee Tunnel Road
source Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 36-42
summary The Ruhrallee is a historical arterial road connecting the wealthy south of the city of Essen with the region south of the city. The old sycamore alley gives the low-density residential neighborhood its spatial qualities and its own identity. But the spatial and social potentials are not legible and livable due to the heavy traffic on the existing road cutting the neighborhood. The street cannot assume its spatial function. Therefore the City of Essen and the Federal Government want to build a tunnel road under the existing street, in order to improve the situation for the neighborhood. The Institute for Urban Design and Planning in cooperation with the Institute for Traffic Planning at the University of Duisburg-Essen carried through an evaluation of various scenarios in terms of traffic flow and visual intrusion of the planned tunnel road as well as the refurbished old street space. The main focus of the study is the integration of the tunnel entrance and the proposed road alignment into the existing urban fabric. The 3D-environmental simulation plays a key role in the analyses, the planning and design process, but also in the decision making process. The paper examines the results of the analyses and the various design schemes. It shows that analogue simulation is still an important tool for urban design and other related planning disciplines. But the paper also points out that 3D-environmental simulation can help to make urban design topics more comprehensible for other non planning disciplines.

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.

summary We developed a synthetic environment design system which not only checks the design but can also create design in realtime. This is significant since there has yet been no existing tool that can accomplish such a task. Along with the development of the tool, we are currently refining the system by applying it to the China Qingdao Jiaonan City Environmental Design Project.

title What people really want - User validation of "digital city" concepts
source SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary This Paper discusses the experience acquired from the user-compatible development of a digital city model as an aid to urban planning based on the endeavours of a large Austrian city. The method selected was a structured survey of the future users of the "Digital City". In the case in question, the addressee is initially an "internal" client, in other words the staff of the Urban Planning Department. Above all findings it seems vital to work more intensive on common terminology and concepts to facilitate the communication between all those involved in creating digital three-dimensional City Models.
