Generic XR game-based approach for industrial training
Santos, Jose Eduardo; Nunes, Miguel; Pires, Marcelo; Rocha, Jose; Sousa, Nuno; Adao, Telmo; Magalhães, Luís Gonzaga Mendes; Jesus, CristianoOver the years several Virtual Reality- (VR) and Augmented Reality- (AR) based learning environments have been proposed. However, they are usually built for a specified scenario and possess a very limited set of configurations. Moreover, the proposed solutions are designed solely to VR- or AR-based learning environments and only a few propose solutions that use both learning environments for training. The prese...
Characterization of the Portuguese SSS into the Europe: A Contribution
Pereira, Maria Teresa Ribeiro; Rocha, Jose; Telhada, José; Carvalho, Maria SameiroNowadays, Short Sea Shipping (SSS) is an essential part in European multi-modal transport system, representing approximately thirty-seven per cent of intra-Community transactions in tonnes per kilometre (tkm). Since 2001, the European Shortsea Network (ESN) in partnership with the short-sea Promotion Centres (SPC) of each Member State of the European Union (EU) have managed to make significant progress in the p...
Symbolic Dynamics and Chaotic Synchronization in Coupled Duffing Oscillators
Caneco, Acilina; Grácio, Clara; Rocha, JoseIn this work we discuss the complete synchronization of two identical double-well Duffing oscillators unidirectionally coupled, from the point of view of symbolic dynamics. Working with Poincar´e cross-sections and the return maps associated, the synchronization of the two oscillators, in terms of the coupling strength, is characterized. We obtained analytically the threshold value of the coupling parameter for ...
Topological entropy in the synchronization of piecewise linear and monotone map...
Caneco, Acilina; Rocha, Jose; Grácio, ClaraIn this paper is presented a relationship between the synchronization and the topological entropy. We obtain the values for the coupling parameter, in terms of the topological entropy, to achieve synchronization of two unidirectional and bidirectional coupled piecewise linear maps. In addition, we prove a result that relates the synchronizability of two m-modal maps with the synchronizability of two conjugated ...
