Radio Coverage Assessment and Indoor Communication Enhancement in Hospitals: A ...
da Silva, Óscar; Teixeira, Emanuel; Corceiro, Ana; Reis, António; Velez, Fernando J.The adoption of wireless medical technologies in hospital environments is often limited by cellular coverage issues, especially in indoor areas with complex structures. This study presents a detailed radio spectrum measurement campaign conducted at the Cova da Beira University Hospital Center (CHUCB), using the NARDA SRM-3006 and R&S®TSME6 equipment. The signal strength and quality of 5G NR, LTE, UMTS, and NB-I...

Silva, Óscar; Teixeira, Emanuel; Corceiro, Ana; Reis, António; Velez, Fernando JoséNos últimos anos, as comunicações moveis celulares e sem fios têm evoluído de forma significativa, possibilitando o surgimento de várias tecnologias que transformaram a forma como nos comunicamos. No contexto da saúde, as Redes Sem Fios de Área Corporal (WBAN) possibilitam a monitorização remota de pacientes, recolhendo e transmitindo dados vitais através de dispositivos localizados ao redor ou dentro do corpo ...
Leveraging Machine Learning for Weed Management and Crop Enhancement: Vineyard ...
Corceiro, Ana; Pereira, Nuno José Matos; Alibabaei, Khadijeh; Gaspar, Pedro DinisThe global population’s rapid growth necessitates a 70% increase in agricultural production, posing challenges exacerbated by weed infestation and herbicide drawbacks. To address this, machine learning (ML) models, particularly convolutional neural networks (CNNs), are employed in precision agriculture (PA) for weed detection. This study focuses on testing CNN architectures for image classification tasks using ...
Methods for Detecting and Classifying Weeds, Diseases and Fruits Using AI to Im...
Corceiro, Ana; Alibabaei, Khadijeh; Assunção, Eduardo Timóteo; Gaspar, Pedro Dinis; Pereira, Nuno José MatosThe rapid growth of the world’s population has put significant pressure on agriculture to meet the increasing demand for food. In this context, agriculture faces multiple challenges, one of which is weed management. While herbicides have traditionally been used to control weed growth, their excessive and random use can lead to environmental pollution and herbicide resistance. To address these challenges, in the...
