Recurrence, Microevolution, and Spatiotemporal Dynamics of Legionella pneumophi...

We investigated molecular evolution and spatiotemporal dynamics of atypical Legionella pneumophila serogroup 1 sequence type 1905 and determined its long-term persistence and linkage to human disease in dispersed locations, far beyond the large 2014 outbreak epicenter in Portugal. Our finding highlights the need for public health interventions to prevent further disease spread.

Guinea-Bissau: avoiding the reputation of being a failed state

This paper poses and answers the following research question: How may Guinea-Bissau overcome its permanent governance instability and avoid becoming a “failed state”? This question is particularly important, not only in the context of circumventing being exposed to the economic interests of external actors, but also, to understand the state domestic weaknesses. Guinea-Bissau is a partially archipelagic small st...

Intrusion Detection for Scalable and Elastic Microservice Applications

Efeito imediato da técnica de rotação cervical grau II na sensação de posição a...

A mobilização articular passiva em indivíduos com dor cervical possui eficácia reconhecida no alívio da dor e no aumento da amplitude articular, mas há poucos estudos sobre a sua influência na capacidade propriocetiva. Estudar o efeito imediato da técnica de rotação cervical grau II na sensação de posição articular, em jovens adultos com e sem dor cervical unilateral de origem não específica. Estudo quase exper...

O valor da informação: em busca de uma unidade de medida

A teorização sobre o valor da informação conheceu ao longo das últimas décadas diferentes abordagens e conceptualizações. No prisma da gestão da informação a reflexão é ainda incipiente e, em Portugal, quase inexistente. Atento a esta realidade, o Grupo de Trabalho de Gestão de Documentos (GT-GDA) da BAD, desde 2021, desenvolver a linha de trabalho “Valor da Informação” com o objetivo de discutir as várias corr...

Ontology based robot reasoning in the elderly care domain - the EUROAGE projects

This paper describes the actions developed and currently in development within the EUROAGE projects related to the ontology-based robot reasoning in the elderly care domain. Recent ontology-based standards were developed (IEEE 1872-2015; IEEE 1872.2-2021; IEEE 7007-2021), and others are currently in development (IEEE P1872.1; IEEE P1872.3) to improve robot performance while executing tasks. This is a very hot t...

Ontological framework to improve motion planning of manipulative agents through...

This paper describes the actions taken in developing a framework that aims to improve the motion planning of a manipulative robotic agent through reasoning based on semantic knowledge. The Semantic Web Rule Language (SWRL) was employed to draw new insights from the existing information about the robotic system and its environment. Recent ontology-based standards have been developed (IEEE 1872-2015; IEEE 1872.2-...

A novel control architecture based on behavior trees for an omni-directional mo...

Robotic systems are increasingly present in dynamic environments. This paper proposes a hierarchical control structure wherein a behavior tree (BT) is used to improve the flexibility and adaptability of an omni-directional mobile robot for point stabilization. Flexibility and adaptability are crucial at each level of the sense–plan–act loop to implement robust and effective robotic solutions in dynamic environm...

Standardizing an ontology for ethically aligned robotic and autonomous systems

Domain-specific ontologies support system design and can establish a framework for fulfilling user-level, safety, or ethical requirements. The IEEE 7007-2021 Ontological Standard for ethically driven robotics and automation systems is the first industry standard to introduce a structure of ontologies concerning robot ethics and related fields, such as data privacy, transparency, responsibility, and accountabili...

Defending the defender: adversarial learning based defending strategy for learn...

Cyber-Physical Systems (CPS) are prone to many security exploitations due to a greater attack surface being introduced by their cyber component by the nature of their remote accessibility or non-isolated capability. Security exploitations, on the other hand, rise in complexities, aiming for more powerful attacks and evasion from detections. The real-world applicability of CPS thus poses a question mark due to s...
