An optical wireless communication system for physiological data transmission in...
Domingues, Ana R.; Pereira, Diogo; Silva, Manuel Fernando Ribeiro; Pimenta, Sara Filomena Ribeiro; Correia, J. H.In biomedical research, telemetry is used to take automated physiological measurements wirelessly from animals, as it reduces their stress and allows recordings for large data collection over long periods. The ability to transmit high-throughput data from an in-body device (e.g., implantable systems, endoscopic capsules) to external devices can also be achieved by radiofrequency (RF), a standard wireless commun...
Design de interação para a web3: plataforma de música como caso de estudo
Pereira, DiogoA adoção das tecnologias associadas à denominada web3 em diversos setores do mercado originaram oportunidades que, por sua vez, levantam novos desafios e barreiras ao seu uso e benefício por parte da população em geral. Entre esses desafios destaca-se o carácter ainda relativamente pouco conhecido do funcionamento de conceitos relacionados com a blockchain tais como smart contracts e NFTs, que se encontram na b...
Exploring the potential of pineapple waste parts in agar film production: chara...
Varghese, Nivin; Costa, Carlota; Marques, Bruno; Pereira, Diogo; Sousa, Clara; Melo, Adma; Ramos, Inês; Silva, Cristina L. M.; Brandão, TeresaAim: Agar films have gained attention as biodegradable packaging materials due to their sustainability and versatility. This study explores the potential use of pineapple waste parts (rind, core, and crown) as a renewable source for agar film production. The aim is to investigate the characteristics and performance of agar films incorporating powdered pineapple subproducts for enhanced packaging applications. M...

Varghese, Nivin; Costa, Carlota; Marques, Bruno; Pereira, Diogo; Sousa, Clara; Melo, Adma; Ramos, Inês; Silva, Cristina L. M.; Brandão, Teresa R. S.Introduction: The excessive use of non-biodegradable plastics in food packaging significantly contributes to environmental pollution and resource depletion. The use of food processing by-products in developing bioplastics and organic films represents a promising strategy for reducing waste and creating value-added products. Pineapple waste, for instance, is rich in fibers and bioactive compounds, making it an i...
Multi-robot coordination for a heterogeneous fleet of robots
Pereira, Diogo; Matos, Diogo; Rebelo, Paulo; Ribeiro, Fillipe; Costa, Pedro; Lima, JoséThere is an increasing need for autonomous mobile robots (AMRs) in industrial environments. The capability of autonomous movement and transportation of items in industrial environments provides a significant increase in productivity and efficiency. This need, coupled with the possibility of controlling groups of heterogeneous robots, simultaneously addresses a wide range of tasks with different characteristics ...

Injection molding of high-precision optical lenses: A review
Peixoto, Carina; Valentim, Pablo T.; Sousa, Patrícia C.; Dias, Diana; Araújo, Cátia; Pereira, Diogo; Machado, Catarina F.; Pontes, A. J.; Santos, HélioInjection molding (IM) is the most efficient mass production technology for manufacturing polymers in complex and detailed geometries with high precision. Although, with the demanding requirements for the optical components, the manufacturing process continues to be a challenge. The majority of optical components require high optical quality with low residual stress, high replication degree, and precisely contr...

O objetivo deste trabalho foi identificar os principais medos e mitos relacionados com a anestesia e cirurgia na nossa população. Material e métodos: Auditoria prospetiva, em que foram...
Biochar-TiO2 magnetic nanocomposites for photocatalytic solar-driven removal of...
Silva, Carla Patrícia; Pereira, Diogo; Calisto, Vânia; Martins, Manuel A.; Otero, Marta; Esteves, Valdemar I.; Lima, Diana L. D.Contamination of surrounding waters with antibiotics by aquaculture effluents can be problematic due to the possible increase of bacterial resistance, making it crucial the efficient treatment of those effluents before their release into the environment. In this work, the application of waste-based magnetic biochar/titanium dioxide (BC/TiO2) composite materials on the photodegradation of two antibiotics widely ...
