The impact of 5G technology on the internet of things and society
Dias, T.; Branco, P. D.; Reis, J. P.The Internet of Things (IoT) and fifth-generation mobile networks (5G) represent two of the most transformative technologies of the 21st century. When integrated, they offer a synergistic foundation for advanced applications in numerous fields, from healthcare to transportation, agriculture, industry, and smart urban infrastructure. IoT enables devices to sense, transmit, and act on data autonomously, while 5G ...
Dimensional optimization of carbon-epoxy bars for reinforcement of wood beams
Reis, J. P.; de Moura, M. F. S. F.; Silva, F. G. A.; Dourado, N.In this work, experimental and numerical studies of wood beams reinforced with an embedded bar of carbon- fibre reinforced polymer were performed. The beams were submitted to three-point bending loading considering three different heights of embedded systems. The experimental load-displacement curves were used to validate a numerical model based on three-dimensional finite element analysis including cohesive zone ...

PAPULO-NODULES LOCATED TO BOTH LOWER EXTREMITIES
Ramos, Leonor; Canelas, M. M.; Vieira, Ricardo; Reis, J. P.; Tellechea, Óscar; Figueiredo, AméricoPerforating diseases are characterized by transepidermal elimination of degenerated material, including collagen or elastic fibers. Acquired perforating dermatosis affects patients with diabetes mellitus or renal disease, especially under dialysis. An 86-year-old diabetic patient presents with very pruritic erythematous-violaceus papules and papulo-nodules, with a central crust. Lesions were evoluting for 2 mon...
Review report on fault detection in sensor networks
Reis, J. P.; Oliveira Costa, C.As redes de sensores têm um largo espectro de aplicações, algumas das quais dizem respeito a estruturas críticas, como é o caso das redes de monitorização estrutural em engenharia civil. Contudo, os sensores, devido à sua natureza e às condições ambientais em que operam, estão sujeitos a falhas que, em ultima instância, podem comprometer a qualidade da informação indispensável para um controlo de segurança efet...
An innovations approach to fault detection in sensor networks - A case study
Reis, J. P.; Almeida Garrett, J.; Oliveira Costa, C.Sensor Networks are widespread across a large spectrum of applications. Some are even deployed in critical infrastructures, as the case of Structure Health Monitoring networks. However the sensors, due to its nature and to the harsh environmental conditions that they withstand, are subject to faults that may compromise the information quality that is indispensable for an effective safety control. In this report...

CABRILAQUIS - Manual do utilizador
Reis, J. P.; Oliveira Costa, C.Apresenta-se o Manual do Utilizador do programa CabrilAquis, parte integrante do sistema de monitorização do comportamento dinâmico da Barragem do Cabril. Este programa controla uma rede de dispositivos e.Pacs (Programmable Automation Controller) que mantém sincronizados, recuperando automaticamente de situações anómalas. Procede ainda à leitura contínua dos conteúdo dos buffers circulares dos equipamentos que ...
