- Air and Underwater Survey of water enclosed spaces for VAMOS! ProjectPublication . Almeida, J.; Ferreira, A.; Matias, B.; Dias, A.; Martins, A.; Silva, F; Oliveira, J.; Sousa, P.; Moreira, M.; Miranda, T.; Almeida, C.; Silva, E.This paper addresses a three-dimensional (3D) reconstruction of a flooded open pit mine with an autonomous surface vehicle (ASV) and unmanned aerial vehicle (UAV). The ROAZ USV and the Otus UAV were used to provide the underwater bathymetric map and aerial 3D reconstruction based from image data. This work was performed wihtin the context of the European researcj project VAMOS with the objective of developing robotic tools for efficient underwater mining
- ISEP/INESC TEC Aerial Robotics Team for Search and Rescue Operations at the EuRathlon Challenge 2015Publication . Sousa, P.; Ferreira, A.; Moreira, M.; Santos, T.; Martins, A.; Dias, A.; Almeida, J.; Silva, E.This paper presents the autononomous aerial vehicle OTUS and its application to search and rescue scenarios, namely the participation on the EuRathlon 2015 competition. The OTUS robot was developed at INESC TEC/ ISEP for research in cooperative aerial robotics and applications in complex and dynamic environments. The system was validated in this challenging scenario and was able to win the Grand Challenge scenario in
- Longitudinal clustering of tuberculosis incidence and predictors for the time profiles: the impact of HIVPublication . Sousa, P.; Oliveira, Alexandra; Gomes, M.; Gaio, A. R.; Duarte, R.BACKGROUND: Portugal remains the country with the highest tuberculosis (TB) incidence in Western Europe. OBJECTIVES: To identify longitudinal trends in TB incidence in Portugal from 2002 to 2012 and investigate the longitudinal effect of sociodemographic and health-related predictors among the resident population on the TB incidence rate. METHODS: We used data from the National Tuberculosis Surveillance System and other national institutions. K-means longitudinal clustering algorithm was performed on TB incidence time profiles from districts of Portugal. RESULTS: Three longitudinal profiles for the TB incidence rate of Portugal were identified. In all of them, TB incidence decreased over time. Among all studied sociodemographic and health-related predictors, human immunodeficiency virus (HIV) notification rate and unemployment were shown to have (positive) significant effects on TB incidence. In particular, the greatest effects were found for the HIV notification rate. CONCLUSIONS: Our study supports the view that combined TB-HIV strategies and the improvement of social determinants can contribute to decreases in TB incidence.
