Assessing the perceptual equivalence of a firefighting training exercise across...
Narciso, David Gonçalves; Rodrigues, Susana; Dias, Duarte; Cunha, João Paulo; Vasconcelos-Raposo, José; Melo, MiguelThe advantages of Virtual Reality (VR) over traditional training, together with the development of VR technology, have contributed to an increase in the body of literature on training professionals with VR. However, there is a gap in the literature concerning the comparison of training in a Virtual Environment (VE) with the same training in a Real Environment (RE), which would contribute to a better understandi...
The effect of hemicylindrical disruptors on the cell free layer thickness in an...
Dias, Duarte; Sampaio, Duarte; Silva, Goncalo; Semião, ViriatoBlood-side resistance to oxygen transport in extracorporeal membrane blood oxygenators (MBO) depends on fluid mechanics governing the laminar flow in very narrow channels, particularly the hemodynamics controlling the cell free layer (CFL) built-up at solid/blood interfaces. The CFL thickness constitutes a barrier to oxygen transport from the membrane towards the erythrocytes. Interposing hemicylindrical CFL di...
Exploring software defined networks for seamless handovers in vehicular networks
Silva, Miguel; Teixeira, Pedro; Anjos Gomes, Christian; Dias, Duarte; Luís, Miguel; Sargento, SusanaWith the growing interest in autonomous driving, constant connectivity for vehicles is becoming essential to enable the complete knowledge of the surrounding area, transmit and receive data that is crucial for the autonomous control. The vehicle mobility results in frequent service interruptions, and therefore, seamless handovers are required to mitigate this problem. Several IP-based solutions have been propos...

iHandU: A Novel Quantitative Wrist Rigidity Evaluation Device for Deep Brain St...
Múrias Lopes, Elodie; Vilas-Boas, Maria do Carmo; Dias, Duarte; Rosas, Maria José; Vaz, Rui; Silva Cunha, João PauloDeep brain stimulation (DBS) surgery is the gold standard therapeutic intervention in Parkinson's disease (PD) with motor complications, notwithstanding drug therapy. In the intraoperative evaluation of DBS's efficacy, neurologists impose a passive wrist flexion movement and qualitatively describe the perceived decrease in rigidity under different stimulation parameters and electrode positions. To tackle this s...
SnapKi—An Inertial Easy-to-Adapt Wearable Textile Device for Movement Quantific...
Oliveira, Ana; Dias, Duarte; Múrias Lopes, Elodie; Vilas-Boas, Maria do Carmo; Paulo Silva Cunha, JoãoThe development of wearable health systems has been the focus of many researchers who aim to find solutions in healthcare. Additionally, the large potential of textiles to integrate electronics, together with the comfort and usability they provide, has contributed to the development of smart garments in this area. In the field of neurological disorders with motor impairment, clinicians look for wearable devices...
Geocodificação de Documentos Textuais com Classificadores Hierárquicos Baseados...
Dias, Duarte; Anastácio, Ivo; Martins, BrunoA maioria dos documentos textuais, produzidos no contexto das mais diversas aplicações, encontra-se relacionado com algum tipo de contexto geográfico. Contudo, os métodos tradicionais para a prospecção de informação em colecções de documentos vêem os textos como conjuntos de termos, ignorando outros aspectos. Mais recentemente, a recuperação de informação com suporte ao contexto geográfico tem capturado a atenç...
O Norte de África como espaço geopolítico
Dias, DuarteTodas as partes do globo são susceptíveis de serem avaliadas geopoliticamente, e o Norte de África não é excepção. A definição deste conjunto geográfico sobre o qual não existe consenso é apenas o início das múltiplas perspectivas em análise. O Norte de África está a emergir ao longo dos últimos anos como um mercado promissor, mas mantendo uma situação política complexa. As economias nacionais e os sectores pri...
