Towards a hardware-in-the-loop quantum optical ground station simulator and tes...
Niehus, Manfred; Simão, José; Silva, João Castanheira da; Serrador, António; Carvalho, João M.; Gonçalves Cavaco Mendes, Mário JoséA single pass Bennett-Brassard 1984 protocol quantum key distribution downlink from a small quantum satellite in low earth orbit to an optical ground station is studied with the objective to develop the framework for a hardware-in-the-loop quantum optical ground station simulator and testbed.
Multimodal emotion evaluation: a physiological model for cost-effective emotion...
Pinto, Gisela; Carvalho, João M.; Barros, Filipa; Soares, Sandra C.; Pinho, Armando J.; Brás, SusanaEmotional responses are associated with distinct body alterations and are crucial to foster adaptive responses, well-being, and survival. Emotion identification may improve peoples' emotion regulation strategies and interaction with multiple life contexts. Several studies have investigated emotion classification systems, but most of them are based on the analysis of only one, a few, or isolated physiological si...
An information-theoretical method for emotion classification
Brás, Susana; Carvalho, João M.; Barros, Filipa; Figueiredo, Cláudia; Soares, Sandra C.; Pinho, Armando J.Identifying the emotion that someone is feeling will allow to improve the experience of the person interaction with environments, devices, and contents. Our body responds to events around us, by emotional responses, reflected in cognitive, behavioral and physiological dimensions. In the present work, we target the electrocardiogram (ECG) response as a mean to express emotions. Its processing is performed using ...
Extended-alphabet finite-context models
Carvalho, João M.; Brás, Susana; Pratas, Diogo; Ferreira, Jacqueline; Soares, Sandra C.; Pinho, Armando J.The Normalized Relative Compression (NRC) is a recent dissimilarity measure, related to the Kolmogorov Complexity. It has been successfully used in different applications, like DNA sequences, images or even ECG (electrocardiographic) signal. It uses a compressor that compresses a target string using exclusively the information contained in a reference string. One possible approach is to use finite-context model...
