Practical Recommendations from Clinical Experts for Optimizing Screening, Diagn...
Mairos, João; Monteiro, Nina; Clode, Nuno; Maricoto, Tiago; Catarino, Rúben; Dias, BrunoIron deficiency is a clinical condition characterized by the depletion of iron stores, potentially affecting up to 95% of pregnant women in Portugal. If not identified and treated early, this condition can progress from fatigue, tiredness and reduced work productivity to anemia, increasing the risk of maternal-fetal complications. Therefore, early detection of iron deficiency during pregnancy is crucial for pro...

On the hexapod Robot's gait optimization: A dynamic perspective on the limbs ac...
Coelho, Joana Sofia Falcato Pereira Lima; Marques, Filipe; Dias, Bruno; Lopes, Gil; Flores, Paulo[Excerpt] It is known that in hexapod robots, the feet’s trajectory is the key feature for generating efficient gait. The kinematic parameters of the feet’s motion, such as the bodies’ velocity when reaching the trajectory’s posterior extreme position, can significantly affect the interaction between the foot and the ground, and consequently, the limb’s actuation. In the literature, common strategies to improve...
Era da (des)informação: conhecimentos e crenças sobre saúde sexual e reprodutiv...
Dias, Bruno; Nuno, JoanaIntrodução: A educação sexual deve assumir uma perspetiva holística, já que desta forma será possível que a camada jovem da população tenha uma vivência gratificante da sua sexualidade. Assim, é de interesse perceber o estado da educação sexual em Portugal. Objetivo: Avaliar os conhecimentos e crenças de adolescentes sobre sexualidade e educação sexual. Métodos: Foi desenvolvido um estudo observacional e analít...
Development and implementation of a new approach for posture control of a hexap...
Coelho, Joana Sofia Falcato Pereira Lima; Dias, Bruno; Lopes, Gil; Ribeiro, A. Fernando; Flores, PauloThe adaptability of hexapods for various locomotion tasks, especially in rescue and exploration missions, drives their application. Unlike controlled environments, these robots need to navigate ever-changing terrains, where ground irregularities impact foothold positions and origin shifts in contact forces. This dynamic interaction leads to varying hexapod postures, affecting overall system stability. This stud...
Dynamic control of a hexapod robot using compliant contact force models
Canedo, João; Coelho, Joana; Marques, Filipe; Dias, Bruno; Lopes, Gil; Ribeiro, A. Fernando; Flores, Paulo[Excerpt] The design of autonomous hexapod robots for rescue or exploratory missions aims to achieve high-performing and efficient locomotion, which must be able to adapt to complex environments with variable terrain topology. In this sense, the contact forces developed during the interaction between the robot’s feet and the ground can cause undesirable trajectory deviations and increase the torso instability d...
Business Intelligence como driver da Análise de Indicadores Académicos
Dias, Bruno; Gonçalves, Célia Talma; Moreira Silva, ManuelO presente artigo aborda o Business Intelligence sob a perspetiva da sua utilidade enquanto driver para a análise de indicadores académicos. Sendo este um conceito de relevo no campo da análise de dados e do apoio ao processo de tomada de decisão, pretende-se demonstrar os benefícios da implementação de um sistema de Business Intelligence numa instituição académica. De forma a atingir esse objetivo principal, é...
Enhancing VRUs safety with V2P communications: an experiment with hidden pedest...
Gonçalves, Fábio Raul Costa; Ribeiro, Bruno Daniel Mestre Viana; Simões, João Henrique Vivas Santos; Gama, Óscar Sílvio Marques AlmeidaVehicular Ad hoc Networks (VANETs) are the network that enables communications between road entities, such as vehicles, Road Side Units (RSUs), or Vulnerable Road Users (VRUs). The work presented in this paper aims to provide a methodology to prevent accidents that happen to VRUs' entities, more precisely, to pedestrians. The goal of this safety application use-case is to detect and warn the involved parties of...
Reactive locomotion of a hexapod for navigation across irregular ground
Coelho, Joana; Dias, Bruno; Lopes, Gil; Ribeiro, A. Fernando; Flores, PauloIn controlled environments, the hexapod limbs actuation can be controlled as a closed system. However, the increase of the terrain complexity implies an adaptation of their trajectory based on the robot interactions with the environment. Thus, the implementation of terrain data to the legs actuation potentially improves the hexapod quasi-static stability in these scenarios. This paper presents an adaptive contr...
Agnostic middleware for VANETs: specification, implementation and testing
Gonçalves, Fábio Raul Costa; Ribeiro, Bruno Daniel Mestre Viana; Gama, Óscar Sílvio Marques Almeida; Nicolau, Maria João; Dias, Bruno; Costa, AntónioVehicular Ad hoc Networks (VANETs) are the basic support for Intelligent Transportation Systems (ITS), providing a framework for its multiple entities to communicate. The communications and services provided to the road entities are generally implemented by means of an On-Board Unit (OBU) and Road Side Unit (RSU), sharing a rather similar hardware and software architectures. These devices need to support multip...
