Sustainability and Automation in Smart Constructions
The real-estate valuation is still complex when it comes to the quantification of the areas and all the factors and coefficients involved in the tax asset value calculation. Automatic methods developed for this purpose have been using various possible approaches and tend to be quite complex for the calculation speed required in most cases. Building Information Modeling (BIM) has as its main advantage the possibility of a precise representation of the geometry of building elements, with integration of information and data in several dimensions. In this sense, this work intends to show the interests that exist in the creation and use of the BIM three-dimensional digital model, providing evidence of the value created for owners, designers, and investors through its use, creating better quality projects and more efficient construction processes, with economy of time and money. The present research work aims to develop the use of an automatic method for the real-estate value calculation, using BIM methodologies. Through BIM, the Architecture, Engineering, Construction, and Operation (AECO) sector can take major evolutions in process optimization, following other major industries. These concepts allow for great speed and efficiency in post-project phases with many advantages compared to current methods. In the scope of the work, an automatic method is developed to calculate the real-estate value in two case studies. The application of the automatic method gains even more importance due to the possibility of its implementation in any developed three-dimensional model. Finally, the results obtained are analyzed and the main conclusions stated.

An Innovative and reliable water leak detection service supported by data-intensive remote sensing processing
The WADI project (Water-tightness Airborne Detection Implementation),integrated within the H2020 initiative, is developing an airborne waterleak detection surveillance service, based on manned and unmanned aerialvehicles. This service aims to provide water utilities with adequate informationon leaks in large water distribution infrastructures outside urban areas. Given thehigh cost associated with water infrastructure networks repairs, a reliability layeris necessary to improve the trustworthiness of the WADI leak identificationprocedure, based on complementary technologies for leak detection. Herein, amethodology based on the combined use of Sentinel remote sensing data and awater leak pathways model is presented, based on data-intensive computing.The resulting water leak detection reliability service, provided to the usersthrough a web interface, targets prompt and cost-effective infrastructure repairswith the required degree of confidence on the detected leaks. The web platformallows for both data analysis and visualization of Sentinel images and relevantleak indicators at the sites selected by the user. The user can also provide aerialimagery inputs, to be processed together with Sentinel remote sensing data at thesatellite acquisition dates identified by the user. The platform provides informationabout the detected leaks location and time evolution, and will be linkedin the future with the outputs from water pathway models

Análise comparada de um agregado de escória de aciaria como material alternativo para lastro de vias férreas do tipo heavy haul por meio de ensaios triaxiais
Este artigo apresenta uma etapa de uma pesquisa mais abrangente que está em andamento na Universidade do Porto, no âmbito do grupo de pesquisa Construct-Geo, que visa avaliar os aspectos geomecânicos de materiais alternativos para uso como camada de lastro em vias férreas do tipo heavy haul. São apresentados resultados de ensaios triaxiais monotônicos e cíclicos conduzidos em corpos de prova de 150 mm de diâmetro por 300 mm de altura, em escala reduzida numa proporção de 1:2,5 em relação à granulometriade lastro padrão AREMA N. 24. Analisou-se um agregado de escória de aciaria, quimicamente e ambientalmente, inerte comparativamente a um agregado de granito, relativamente à resistência e à deformabilidade. Os ensaios cíclicos foram conduzidos em dois escalões de carga de 500.000 ciclos, sendo cada escalão compatível com o carregamento imposto por vias do tipo heavy haul com, respectivamente,32,5 toneladas/eixo e 40 toneladas/eixo. Os resultados mostraram que o lastro de escória de aciaria apresentou parâmetros de resistência superiores comparativamente ao lastro de granito e um melhor comportamento quanto à deformabilidade, expresso por maiores valores de módulo de resiliência, menoresíndices de quebra e degradação de partículas e uma maior tendência de estabilização das deformações plásticas, fenômeno conhecido como shakedown e que também foi investigado.

DEM modelling of the non-linear static and dynamic response of masonry structures
Discrete element models have become a major tool for masonry analysis, allowing a suitable representation of its discontinuous nature and marked nonlinear behaviour. The chapter reviews the fundamental assumptions of the main DEM formulations available. It focuses more specifically on the widely used UDEC and 3DEC codes, explaining their relation with the other approaches, and the most relevant issues arising in their application to masonry. Applications to the main types of structures are reviewed, considering both static and dynamic analyses. Recent research providing comparisons of the numerical models with experimental and field data is particularly covered. The discussion of the different examples is aimed at clarifying the key capabilities of DEM and demonstrating the most effective ways of using it in a variety of masonry analysis situations.

Digital in action in a neighbourhood in transformation: Notes from Mouraria in Lisbon
The chapter considers the link between urban transformations in the Mouraria neighbourhood in Lisbon and the digital environment.The guiding thread of reflection is based on the tension between the production of sociocultural symbolic local references, and their (dis)appropriation by a creative economy that, relying on digital as a resource, helps to reshape the sociocultural local world into marketing. It concludes that digital has, not only a tangible social dimension, but also a tangible dimension in the processes of urban transformation. As such, it is pertinent to create alternative ways in defence of the right to the city that economize the social and its imageries taking more advantage of the articulated combination between real-digital.

Opencoasts: an open-access app for sharing coastal prediction information for management and recreation
Coastal forecast systems provide coastal managers with accurate and timely hydrodynamic predictions, supporting multiple uses such as navigation, water monitoring, port operations and dredging activities. They are also useful to support recreational activities. Still, the widespread use of coastal forecasts is limited by the unavailability of open forecasts for consultation, the expertise needed to build operational forecast systems and the human and computational resources required to maintain them in operation every day. A new service for the generic deployment of forecast systems at user-specified locations was developed to address these limitations. Denoted OPENCoastS, this service builds circulation forecast systems for user-selected coastal areas and maintains them in operation using the European Open Science Cloud (EOSC) computational resources. OPENCoastS can be applied to any coastal region and has been in operation since 2018, forced by several regional and global forecasts of the atmospheric and ocean dynamics. It has attracted over 150 users from around 45 institutions across the globe. However, most users come from research institutions. The only requirement needed to use this service

Seismic and Structural Health Monitoring of Dams in Portugal
This chapter is focused on the Portuguese experience on the developmentand exploration of systems for continuously monitoring dam vibrations, usingaccelerometers. The pioneer system for seismic and structural health monitoring(SSHM) installed in Cabril dam (the highest Portuguese arch dam: 132 m high) isdescribed in detail. The design of this system was the result of a long-term LNECresearch program, still ongoing. These monitoring systems should include softwaredeveloped to automatically perform the analysis of collected data, including theautomatic comparison with numerical results from 3DFE models. In view of thegood results obtained with the system in operation in Cabril dam since 2008, similarsystems have been installed in other large dams in Portugal, particularly in recentlybuilt dams. Finally, Baixo Sabor dam is presented as an example of a new Portuguesedam with a complete SSHM system, in operation since 2015. Themain experimentalresults obtained for both dams are shown, namely the evolution of natural frequenciesover time, mode shapes and the measured seismic response to earthquake events.

Shaping favorable beliefs towards seismic protection through risk communication: A pilot-experience in two Lisbon schools (Portugal).
Communicating science within disaster risk reduction using methods that encourage two-way dialogue between scientists and laypersons is a challenging task. This paper aims at presenting a methodological strategy of communicating risk and non-structural seismic protection measures through participatory approach. Such methodological strategy is part of a pilot experience of risk communication in two schools in Lisbon (Portugal) under the EU project KnowRISK (Know your city, Reduce seISmic risK through non-structural elements). The efficacy of education for seismic safety is often inhibited by an incomplete understanding of the process by which individuals decide to protect themselves from harm (Becker JS, Paton D,Johnston DM, Ronan KR.

Towards a framework for understanding the synergies between public spaces, people and technologies
This chapter is concerned with how digital technologies are changing habits, expectations and motivations in the use of public open spaces. These digital developments are a societal challenge with reflections on social practices and, on planning and design approaches to public spaces. This might also challenge the future development of information and communication technologies (ICTs). The discussion in this Chapter is based on knowledge and experience exchanges carried out within the COST Action CyberParks. The leading issue of CyberParks is how to use ICTs to transform our cities into more human environments, rather than just more high-tech places, and to understand that smartness should be people friendly. Through the structure of the project, the importance of comprehensive and trans-disciplinary development is introduced and justified. A theoretical approach and frameworks from ethnographic and technological perspectives that help us to better understand (potential) interactions are being developed, and both are at the centre of this discussion.
