A presente dissertação teve como finalidade estudar os testemunhos arqueológicos respeitantes às práticas funerárias levadas a cabo no atual concelho de Cascais durante os séculos VI e VII. As necrópoles em estudo são sítios bem conhecidos pelos investigadores, uma vez que a descoberta de algumas é precoce, datando de finais do século XIX. Com este trabalho, pretendeu-se introduzir uma série de componentes que a investigação privilegia atualmente, sobretudo no que respeita às vivências nos espaços rurais entre o fim do Império Romano e o domínio muçulmano na Península Ibérica. A investigação desenvolvida baseou-se no estudo preliminar das coleções osteológicas de quatro das cinco necrópoles, bem como na prospeção e no levantamento arqueológicos. O inventário antropológico teve como objetivo apurar o número mínimo de indivíduos por necrópole e por sepultura e fazer uma caracterização básica do sexo e da idade dos inumados. A prospeção assentou na análise das fontes bibliográficas sobre os sítios. Os trabalhos de campo desenvolveram-se no sentido de apurar o estado de conservação dos vestígios, na eventual identificação de outros novos e no consequente levantamento gráfico e fotográfico dos mesmos. Foi igualmente examinado o espólio cerâmico e metálico recolhido aquando da escavação das necrópoles, de modo obter uma visão abrangente sobre os rituais funerários e a estabelecer cronologias mais precisas. Embora se trate de um estudo limitado devido à inexistência de um registo mais rigoroso dos vestígios, foi possível tirar algumas conclusões e constatar alguns padrões. Os resultados possibilitaram apontar um conjunto de condições que se repetem nos locais onde estes cemitérios se implantam, percebendo dinâmicas em relação a fatores de caráter natural e de carácter antrópico. Também se apurou que existiriam diferentes formas de organizar os espaços funerários e que estes seriam constituídos por sepulturas muito diversas do ponto de vista construtivo. Além disso, começa-se a desvelar as razões para a reutilização de sepulturas para vários enterramentos e a entender a forma como as comunidades rurais conduziam os rituais funerários, ainda muito enraizados numa antiga matriz pagã.

Since the last decade of the twentieth century, the healthcare industry is paying attention to the environmental impact of their buildings and therefore new regulations, policy goals and Buildings Sustainability Assessment (HBSA) methods are being developed and implemented. At the present, healthcare is one of the most regulated industries and it is also one of the largest consumers of energy per net floor area. To assess the sustainability of healthcare buildings it is necessary to establish a set of benchmarks related with their life-cycle performance. They are both essential to rate the sustainability of a project and to support designers and other stakeholders in the process of designing and operating a sustainable building, by allowing the comparison to be made between a project and the conventional and best market practices. This research is focused on the methodology to set the benchmarks for resources consumption, waste production, operation costs and potential environmental impacts related to the operational phase of healthcare buildings. It aims at contributing to the reduction of the subjectivity found in the definition of the benchmarks used in Building Sustainability Assessment (BSA) methods, and it is applied in the Portuguese context. These benchmarks will be used in the development of a Portuguese HBSA method.

Joints play a major role in the structural behaviour of old timber frames [1]. Current standards mainly focus on modern dowel-type joints and usually provide little guidance (with the exception of German and Swiss NAs) to designers regarding traditional joints. With few exceptions, see e.g. [2], [3], [4], most of the research undertaken today is mainly focused on the reinforcement of dowel-type connections. When considering old carpentry joints, it is neither realistic nor useful to try to describe the behaviour of each and every type of joint. The discussion here is not an extra attempt to classify or compare joint configurations [5], [6], [7]. Despite the existence of some classification rules which define different types of carpentry joints, their applicability becomes difficult. This is due to the differences in the way joints are fashioned depending, on the geographical location and their age. In view of this, it is mandatory to check the relevance of the calculations as a first step. This first step, to, is mandatory. A limited number of carpentry joints, along with some calculation rules and possible strengthening techniques are presented here.

This work intends to present a newly developed test setup for dynamic out-of-plane loading using underWater Blast Wave Generators (WBWG) as loading source. Underwater blasting operations have been, during the last decades, subject of research and development of maritime blasting operations (including torpedo studies), aquarium tests for the measurement of blasting energy of industrial explosives and confined underwater blast wave generators. WBWG allow a wide range for the produced blast impulse and surface area distribution. It also avoids the generation of high velocity fragments and reduces atmospheric sound wave. A first objective of this work is to study the behavior of masonry infill walls subjected to blast loading. Three different masonry walls are to be studied, namely unreinforced masonry infill walls and two different reinforcement solutions. These solutions have been studied previously for seismic action mitigation. Subsequently, the walls will be simulated using an explicit finite element code for validation and parametric studies. Finally, a tool to help designers to make informed decisions on the use of infills under blast loading will be presented.

[Extrat] Thermoplastic profiles are very attractive due to their inherent design freedom. However, the usual methodologies employed to design extrusion forming tools, based on experimental based trial–and–error procedures, are highly dependent on the designer’s experience and lead to high resources consumption. Despite of the relatively low cost of the raw materials employed on the production of this type of profiles, the resources involved in the die design process significantly increase their cost. These difficulties are even more evident when a complex geometry profile has to be produced and there is no previous experience with similar geometries. Therefore, novel design approaches are required, in order to reduce the required resources and guarantee a good performance for the produced profile. (...)

The morphological evolution of the city of Braga has been the subject of several studies focusing on different urban areas in different periods. Using the accumulated knowledge provided by the available archaeological, historical and iconographic data of Braga, from the Roman times to the nineteenth century, we intend to present a working methodology for 3D representation of urban areas and its evolution, using the CityEngine ESRI tool. Different types of graphic and cartographic data will be integrated in an archaeological information system for the characterization of urban buildings. Linking this information system to the rules of characterization of urban spaces through the CityEngine tool, we can create the 3D urban spaces and their changes. The building characterization rules include several parameters of architectural elements that can be dynamically changed according the latest information. This methodology will be applied to the best known areas within of the city allowing the creation of different and dynamic layouts. Considerations about the concepts, challenges and constraints of using the CityEngine tool for recording and representing urban evolution knowledge will be discussed.
