Pleural Solitary Tumors – Long-Term Prognosis Related To Surgery And Clinicopat...
Almeida, Vânia; Veloso, Luis; Cunha, Sara; Carvalho, LinaIntroduction: Pleural solitary fibrous tumors (SFTs) are indolent mesenchymal neoplasias, generally with good prognosis, for which complete surgical resection is the gold standard. However, local recurrences and distant metastases are reported at variable rates. Risk-assessing criteria and models determining recurrence and metastatic risk have been proposed, and can impact on patient follow-up strategies. Metho...
Biodiversidade em habitats naturais e seminaturais da baixa do rio Seia
Veloso, Luis; Silva, Alexandre; Nunes, Leónia; Costa, Cristina A.A baixa do rio Seia alberga uma grande diversidade florística que se organiza em diversos habitats naturais e seminaturais. É possível encontrar, nesta área, locais com presença de vegetação potencial, ainda que esta baixa tenha sido alvo de intensa intervenção humana, bem como espécies relevantes em termos de conservação. O principal objetivo deste trabalho foi contribuir para a preservação dos habitats e espé...
Towards Sustainable Digital Twins for Vertical Farming
Monteiro, José; Barata, João; Veloso, Marco; Veloso, Luis; Nunes, JoãoLink https://ieeexplore.ieee.org/abstract/document/8847169; We present a model to implement digital twins in sustainable agriculture. Our two-year research project follows the design science research paradigm, aiming at the joint creation of physical and digital layers of IoT-enabled structures for vertical farming. The proposed model deploys IoT to (1) improve productivity, (2) allow self-configuration to envi...
QoS mapping and adaptation in next generation networks
Cerqueira, Eduardo Coelho; Sousa, T.; Venâncio Neto, Augusto José; Veloso, Luis; Curado, Marília; Monteiro, EdmundoThe end-to-end Quality of Service (QoS) control is one of the key factors to the success of next generation networks. Therefore, this paper presents a sessionaware QoS mapping and adaptation mechanism that maps the session QoS requirements into the most suitable network service class across heterogeneous mobile networks as well as it adapts the session to the current network conditions. The proposed scheme allo...
Q3M: QoS architecture for multi-user mobile multimedia sessions in 4G systems
Cerqueira, Eduardo Coelho; Veloso, Luis; Venâncio Neto, Augusto José; Curado, Marília; Mendes, Paulo; Monteiro, EdmundoFourth generation systems (4G) will provide multimedia group communication sessions to multiple mobile users with distinct requirements. This way, it is expected the control of the quality level, connectivity and ubiquitous access for multi-user multimedia sessions across heterogeneous and mobile networks with seamless capability. This paper analyses the requirements of a control architecture to provide Quality...
Control of multi-user services in mobile heterogeneous environments
Cerqueira, Eduardo Coelho; Venâncio Neto, Augusto José; Veloso, Luis; Monteiro, EdmundoNowadays the Internet provides a wide variety of multi-user communication services over heterogeneous environments, where services are destined for large audiences, independently of the location of users and of the moment when those services are requested. Having this in mind, this paper proposes a QoS Architecture for Multimedia Mobile Multi-user (Q3M) support, to allow mobile operators to control the dissemin...
A unifying architecture for publish-subscribe services in the next generation I...
Cerqueira, Eduardo Coelho; Veloso, Luis; Venâncio Neto, Augusto José; Curado, Marília; Monteiro, Edmundo; Mendes, PauloNext generation IP networks are envisioned to be heterogeneous, to provide a wide variety of services, and to support mobility of users with distinct requirements. Moreover, mobile communications are expected to expand from telephony to publish-subscribe services, such as real-time multimedia. With this goal, the University of Coimbra is working with DoCoMo Euro-Labs on a unifying control architecture for multi...
Mobility management for multi-user sessions in next generation wireless systems
Cerqueira, Eduardo; Veloso, Luis; Neto, Augusto; Curado, Marília; Monteiro, Edmundo; Mendes, PauloMobility management and ubiquitous access for real-time multi-user sessions with Quality of Service (QoS) support are major requirements to the success of next generation wireless systems. In this context, Multi-User Session Control (MUSC) is proposed to allow fixed and mobile users to access multi-user sessions ubiquitously, while providing QoS mapping, QoS adaptation and connectivity control in heterogeneous ...
QoS Support for Multi-user Sessions in IP-based Next Generation Networks
Cerqueira, Eduardo; Veloso, Luis; Neto, Augusto; Curado, Marília; Monteiro, Edmundo; Mendes, PauloAbstract A combined control of multimedia quality level, mobility and allocation of network resources is essential for the success of next generation mobile networks. In this context, this article presents the Multi-user Session Control (MUSC) solution to control the quality level of multimedia sessions shared by multiple-users, providing Quality of Service (QoS) mapping and QoS adaptation for those sessions ov...
