Franco-German leadership in the context of EU defence policy: From Brexit to th...
Ribeiro, I. M.; Rosa, J.; Xavier, A. I.Leadership is crucial for the success of a collective actor in reaching common goals. Its relevance is particularly visible in the EU, due to the difficulty in managing and converging a wide range of interests, especially in the intergovernmental field of defence. This article analyses Franco-German transactional leadership throughout the evolution of the EU’s security and defence policy, with a focus on the ef...
Trigaches Marbles (São Brissos, Beja, Portugal): petrographic and geochemical c...
Rosa, J.; Moreira, N.; Santos, J. F.; Ribeiro, S.The exploitation of carbonate crystalline rocks in the Ossa-Morena Zone (OMZ) dates back more than two thousand years. Several historical exploitation poles in OMZ were identified based on the identification of distinctive marble lithotypes in Roman consumption areas, and some of those historical exploitation places were, subsequently, identified in situ through geo-archaeological works (e.g. Almadén de la Plat...
Intelligent clinical decision support system for managing COPD patients
Pereira, J.; Antunes, N.; Rosa, J.; Ferreira, J.; Mogo, S.; Pereira, M.Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide. Health remote monitoring systems (HRMSs) play a crucial role in managing COPD patients by identifying anomalies in their biometric signs and alerting healthcare professionals. By analyzing the relationships between biometric signs and environmental factors, it is possible to develop artificial intelligence models that ar...
Wind power forecasting with machine learning: single and combined methods
Rosa, J.; Pestana, Rui; Leandro, Carlos; Brás-Geraldes, Carlos; Esteves, João; Carvalho, D.In Portugal, wind power represents one of the largest renewable sources of energy in the national energy mix. The investment in wind power started several decades ago and is still on the roadmap of political and industrial players. One example is that by 2030 it is estimated that wind power is going to represent up to 35% of renewable energy production in Portugal. With the growth of the installed wind capacity...
Grid-based vessel deviation from route identification with unsupervised learning
Antunes, N.; Pereira, J.; Rosa, J.; Ferreira, J.The application of anomaly-monitoring and surveillance systems is crucial for improving maritime situational awareness. These systems must work on the fly in order to provide the operator with information on potentially dangerous or illegal situations as they are occurring. We present a system for identifying vessels deviating from their normal course of travel, from unlabelled AIS data. Our approach attempts t...
Influence of oceanic and climate conditions on the early life history of Europe...
Pinto, M.; Monteiro, J. N.; Crespo, D.; Costa, F.; Rosa, J.; Primo, A. L.; Pardal, M. A.; Martinho, F.Understanding how marine fish early-life history is affected in the long-term by environmental and oceanographic factors is fundamental given its importance to population dynamics and connectivity. This work aimed at determining the influence of these processes on the interannual variability in hatch day and early-life growth patterns of European seabass, over a seven-year period (2011-2017) in the Atlantic Ibe...

Morphodynamic evolution of a sand extraction excavation offshore Vale do Lobo, ...
Gonçalves, D. S.; Pinheiro, L. M.; Silva, P. A.; Rosa, J.; Rebêlo, L.; Bertin, X.; Braz Teixeira, S.; Esteves, R.Offshore sand and gravel extraction for aggregates and beach nourishment is an important economic activity and has been a common practice in various countries worldwide for many years. The evolution of a sandpit, in particular its migration and rate of replenishment, depends strongly on the type of sediments involved, and on the physical and hydrodynamic characteristics of the surrounding area. In order to full...
Waves, wind and tidal forcing on a sandpit morphodynamics
Rosa, J.; Silva, P. A.; Bertin, X.; Fortunato, A. B.Due to the increasing demand of sand for construction and beach nourishment, offshore extraction is being considered as an alternative source. Long term morphological changes caused by such an extraction must be predicted because they can affect the sediments budget and potentially promote coastal erosion. Numerical models are powerful tools that can help in the evaluation of environmental impacts induced by th...
