CaseScope: An Enhanced Search Tool for European Court Cases
Correia, Alexandre; Evangelista, Pedro; Soares, Nádia; Rocha, Eugénio; Teixeira, CláudioNatural Language Processing (NLP) is a rapidly growing field of research, enabled by advances in computer power and deep learning models. As a subfield of Artificial Intelligence, NLP can help with tasks such as Named Entity Recognition and Sentiment Analyses by extracting meaningful connections between words from a text. New architectures for neural networks like transformers have been responsible for a great ...
Smart Thermostats for a Campus Microgrid: Demand Control and Improving Air Quality
Correia, Alexandre; Ferreira, Luís Miguel; Coimbra, Paulo; Moura, Pedro; de Almeida, AníbalAchieving nearly zero-energy buildings (nZEB) is one of the main objectives defined by the European Union for achieving carbon neutrality in buildings. nZEBs are heavily reliant on distributed renewable generation energy sources, which create new challenges associated with their inherent intermittency. To achieve nZEB levels, demand management plays an essential role to balance supply and demand. Since up to tw...
Climatology and nutrient fluxes in the Tagus estuary: A coupled model application
de Pablo, Hilda; Sobrinho, João; Nunes, Susana; Correia, Alexandre; Neves, Ramiro; Gaspar, MiguelRivers are responsible for the main transport of nutrients from land to estuaries and coastal areas. Understanding the fate of these anthropogenic inputs and their impacts on estuaries and adjacent marine ecosystems is essential for the protection of coastal waters. Here, the 3D MOHID hydrodynamic model coupled with a biogeochemical model was used to determine seasonal nutrient fluxes between areas of the Tagus...

The EChO science case
Tinetti, Giovanna; Drossart, Pierre; Eccleston, Paul; Hartogh, Paul; Isaak, Kate; Linder, Martin; Lovis, Christophe; Micela, Giusi; Ollivier, MarcThe discovery of almost two thousand exoplanets has revealed an unexpectedly diverse planet population. We see gas giants in few-day orbits, whole multi-planet systems within the orbit of Mercury, and new populations of planets with masses between that of the Earth and Neptune-all unknown in the Solar System. Observations to date have shown that our Solar System is certainly not representative of the general po...
Gliomas do Quiasma Óptico na Criança: Avaliação Retrospectiva
Carvalho, Alice; Heitor, Fátima; Brito, Manuel; Baptista, Rui; Costa, José Augusto; Correia, Alexandre; Pais, Rui PedroObjectivos: As opções terapêuticas na abordagem do Glioma do Quiasma Óptico são várias, mas nenhuma isenta de complicações. Avaliou-se a resposta a diferentes terapêuticas e sequelas, nas crianças com Glioma do Quiasma Óptico, diagnosticadas no Hospital Pediátrico de Coimbra Material e Métodos: Analisaram-se 11 casos diagnosticados de 1984 até 1999 com idade 8 anos. Estabeleceram-se 2 grupos (Grupos A e B), de ...
Modelling the Mechanical Behavior of Polymer-Based Nanocomposites
Correia, Alexandre; Valashani, S. Mohsen; Pires, Francisco; Simões, RicardoMolecular dynamics simulations were employed to analyze the mechanical properties of polymer-based nanocomposites with varying nanofiber network parameters. The study was focused on nanofiber aspect ratio, concentration and initial orientation. The reinforcing phase affects the behavior of the polymeric nanocomposite. Simulations have shown that the fiber concentration has a significant effect on the properties...

Frontal Mass: Diagnostic Challenges
Rubino, Gina; Correia, Alexandre; Rodrigues, FernandaCapnocytophaga spp. are part of the oral flora of humans and animals, being responsible for skin and soft tissues infections and invasive infections. Microbiological identification can be difficult due to its slow growth. We present a case of infection caused by this bacteria in the form of an extracerebral intracranial abscess, presenting as a frontal mass that posed some diagnostic challenges. A surgical drai...
Coupling mechanical and electrical behavior in the multi-scale simulation of po...
Simões, Ricardo; Correia, Alexandre; Silva, Jaime; Lanceros-Méndez, S.A numeric model has been proposed to investigate the mechanical and electrical properties of a polymeric/carbon nanotube (CNT) composite material subjected to a deformation force. The reinforcing phase affects the behavior of the polymeric matrix and depends on the nanofiber aspect ratio and preferential orientation. The simulations show that the mechanical behavior of a computer generated material (CGM) depend...
