Customized Ceramics

Mass Customization of Ceramic Tableware
Eduardo Castro e Costa orientado por José Pinto Duarte, Joaquim Jorge, and Paulo Bártolo

The aim of this research is to allow potential customers to design ceramic tableware elements tailored to their needs and taste. The serial customization thus enables companies of the ceramic industry to offer unique products and services to their customers, increasing their competitiveness through innovation.

The implementation of mass customization implies the development of a design system, i.e., a coherent system of rules that can generate objects of a certain type in a particular style. For developing the system design we will study the design of objects, namely shape and decoration, under the light of computational paradigms such as parametric modelling or shape grammars.

The adopted serial customization model also includes an automated production system and a computer system, whose development will have a close linkage with the project design. In order to implement such automatic production system, digital fabrication technologies will be studied, such as 3D printing, and their potential application in the industrial context. Regarding the implementation of the computer system, particular attention is paid to the interaction with the user.

Research topics: shape grammars, parametric modelling, digital fabrication

Emergence and Composition

The multi-dimensional analysis and design of the public open space
João Ventura Lopes orientado por Alexandra C. Paio (adviser); José Nuno Beirão (co-adviser); Eliana Pinho (co-adviser)

Na sociedade contemporânea o acto projectual é ineludível e a complexidade do contexto urbano desafia os arquitectos a definirem abordagens transdisciplinares inovadoras. O saber e teoria das disciplinas da morfologia urbana e da análise espacial cognitiva-comportamental do espaço público, apesar de interceptarem o dos desenhos urbano, não se encontram integrados. O espaço público requer resiliência, adaptabilidade a comportamentos e padrões de uso cambiantes, e qualidades que possam ser aferidas antecipadamente. A praça e os espaços informais do vazio urbano não classificado, como elementos de excepção e articulação do tecido urbano, são o nosso objecto de estudo. A análise da emergência de singularidades em sistemas planeados e não-planeados, e a aferição de correlações entre parâmetros de qualidade urbana e da análise multidimensional de um corpus desses espaços, ilustrativo da sua variedade no território nacional, alimentará um Modelo de projecto capaz de sintetizar organicamente propostas de reconversão ou criação destas estruturas. Para isso recorreremos a métodos quantitativos e qualitativos de análise formal e espacial e a técnicas computacionais de data mining e de projecto urbano paramétrico e generativo.

Chair DNA

Contributions to the study of the form: development of a computational model applied to the chair
Sara Garcia orientado por Luís Romão

Product classes share the same basic abstract layout, despite its great diversity. This research expects to (de)code the variety of types embedded in the multipurpose chairs class. The contribution relies on the development of a generative design tool, to be used at the conceptual chair design stage. It is proposed a framework of five stages: (1) sample definition, considering chairs with a large diversity of types; (2) analysis of the syntax and semantics of the class through ontology classification; (3) development of a generic shape grammar, applied to product design; (4) implementation of a digital tool, that provides an interface to manipulate the chair components visualized in a 3D digital model; and (5) user evaluation of the program, in order to take conclusions on the usability and usefulness of the tool and to gain outcomes for further developments.

CityPlan

Towards development of a methodology and computational tool to support urban design
Nuno Montenegro orientado por José Pinto Duarte, Paulo Urbano

This thesis describes the development of a model for the formulation of urban programs that includes the creation of a methodology and an associated computational tool, named CityPlan. The content of the research focuses on the development of a planning paradigm supported by computational ontologies, in the context of the “Web Ontology Language” (OWL) technology. Basically CityPlan consists of a “Geographic Information System” based on ontologies (GIS-O).
The main purpose for CityPlan is to help stakeholders in the processes of urban development, to enable the creation of urban intervention programs, benefiting from the advantages of the aforementioned model and technology. With CityPlan, it is possible to semantically annotate an intervention site with knowledge about the land use and the population, and then locate, automatically, a set of collective public facilities according to their specific location rules.
Having identified the main requirements of the plan, it is possible to establish a basic set of appropriate recommendations, to support the creation of spatial planning strategies and consistent urban design alternatives.

Keywords: Urban planning, ontologies, GIS-O, Ontology Web Language, OWL 2.0.
