Dankina, Darja; Carvalho, Victor; Silva, Bruno Camilo; Costa, Bruno; Balbino, Ausenda; Fialho, PedroThe Lusitanian Basin is located in the western part of Portugal (mainland), which was formed during the opening of North Atlantic Ocean in the beginning of Mesozoic Era. The geological cross section of this basin is reached approximately 5-6 km thickness and consists of Upper Triassic to Lower Cretaceous sedimentary deposits. The infill sequences of sedimentary rocks in this basin were formed under several phas...

Stress among portuguese medical students: the EuStress solution
Silva, Eliana; Aguiar, Joyce; Reis, L. P.; Oliveira e Sá, Jorge; Gonçalves, Joaquim; Carvalho, VictorThere has been an increasing attention to the study of stress. Particularly, college students often experience high levels of stress that are linked to several negative outcomes concerning academic functioning, physical, and mental health. In this paper, we introduce the EuStress Solution, that aims to create an Information System to monitor and assess, continuously and in real-time, the stress levels of the st...
Assessing daily activities using a PPG sensor embedded in a wristband-type acti...
Oliveira, Alexandra; Aguiar, Joyce; Silva, Eliana; Faria, Brígida Mónica; Gonçalves, Helena; Teófilo, Luís; Gonçalves, Joaquim; Carvalho, VictorDue to the technological evolution on wearable devices, biosignals, such as inter-cardiac beat interval (RR) time series, are being captured in a noncontrolled environment. These RR signals, derived from photoplethysmography (PPG), enable health status assessment in a more continuous, non-invasive, nonobstructive way, and fully integrated into the individual’s daily activity. However PPG is vulnerable to motion...
An approach to assess quality of life through biometric monitoring in cancer pa...
Silva, Eliana; Aguiar, Joyce; Oliveira, Alexandra; Faria, Brígida Mónica; Reis, Luís Paulo; Carvalho, Victor; Gonçalves, Joaquim; Oliveira e Sá, JorgeCancer is a serious disease that causes significant disability and suffering, so naturally Health Related Quality of Life (HRQoL) is a major concern of patients, families and clinicians. This paper intends to relate biometric indices, in terms of HRV metrics, with self-perceived HRQoL from patients with lymphoma. Patients (N = 12) answered FACT questionnaire and used a smartband that collected biometrical data ...
Information system for monitoring and assessing stress among medical students
Silva, Eliana; Aguiar, Joyce; Reis, Luís Paulo; Oliveira e Sá, Jorge; Gonçalves, Joaquim; Carvalho, VictorThe severe or prolonged exposure to stress-inducing factors in occupational and academic settings is a growing concern. The literature describes several potentially stressful moments experienced by medical students throughout the course, affecting cognitive functioning and learning. In this paper, we introduce the EUSTRESS Solution, that aims to create an Information System to monitor and assess, continuously a...
