Precision landing for low-maintenance remote operations with UAVs
Moreira, Miguel; Azevedo, Fábio; Ferreira, André; Pedro, Dário; Matos-Carvalho, João; Ramos, Álvaro; Loureiro, Rui; Campos, LuísThis work proposes a fully integrated ecosystem composed of three main components with a complex goal: to implement an autonomous system with a UAV requiring little to no maintenance and capable of flying autonomously. For this goal, was developed an autonomous UAV, an online platform capable of its management and a landing platform to enclose and charge the UAV after flights. Furthermore, a precision landing a...

Peak oxygen uptake differentiates competitive from recreational male surfboard ...
Almeida, Nuno; Reis, Joana; Beckert, João; Moreira, Miguel; Alves, FranciscoThe purpose of this study was to verify if competitive performance status was associated to different levels of specific aerobic fitness in Portuguese surfboard riders. Six recreational surfers (age: 32.3±3.1 years; body mass: 73.2±7.8kg; height: 1.75±0.05m) and six competitive international level surfers (age: 25±8.4years; body mass: 68.5±3.8kg; height: 1.74±0.05m) performed a maximal continuous incremental pa...
Developing a Planning and Management System for Protected Areas on Small Island...
Calado, Helena; Horta de Sousa Vergílio, Marta; Fonseca, Catarina; Gil, Artur; Moniz, Fabiana; Silva, Susana Ferreira; Moreira, MiguelUID/SOC/04647/2013; Small Islands face particular challenges in their sustainable development, and therefore require specific tailored approaches for planning and management. Unsurprisingly, protected areas have a special role in the conservation of biodiversity and natural resources crucial to the sustainability of such territories. How should the management and planning system of protected areas in small isla...
