    A reabilitação de edifícios, no contexto europeu, continuará a crescer nos próximos anos, até se consolidar como um sector de grande importância no conjunto da construção. Para acompanhar esta realidade, é importante desenvolver uma nova metodologia de inspecção exigencial de modo a que todos os intervenientes no processo de reabilitação de edifícios, disponham de um instrumento de trabalho que permita rapidamente obter informações correctas e adequadas sobre o edifício objecto de intervenção. info:eu-repo/semantics/publishedVersion

    The deployment of fifth-generation wireless communications (5G) networks brought a significant difference in the data rate and throughput to the wireless systems. It ensures ultra-low latency and high reliability. In particular, Network Slicing (NS), one of the enablers for the 5G phase-II and beyond, has opened enormous opportunities for the Communications Service Provider (CSPs). NS allows CSPs to create independent virtual networks in the same physical network to guarantee high service levels. This paper provides an overview of the advances in NS from the perspective of the business opportunities and associated standardization activities. Standardization is critical in research as it intends to maintain interoperability among multi-vendor scenarios in telcos. We emphasize highlighting the technical facets of slicing within the business implementation and industry standardization process. Additionally, we address the application of Artificial Intelligence (AI) and Machine Learning (ML) to NS-enabled future networks deployments. A set of use cases and the underlying specific requirements challenges are discussed as well. Finally, future research directions are addressed in detail. info:eu-repo/semantics/acceptedVersion

    Em muitas sociedades pré-industriais a transformação de matéria-prima em tecido é tarefa de mulheres. Habilidade e destreza nestas actividades conferem prestígio a uma mulher, tanto perante outras mulheres como na sociedade em geral. Nesta comunicação cita-se e descreve-se algumas técnicas que são utilizadas em sociedades asiáticas, na fiação, na tecelagem e na tinturaria. Nos países do Sueste Asiático, tecer e o tecido estão estreitamente ligados a forças sobrenaturais. Reconhece-se a actuação de forças espirituais que ajudam no processo de tecelagem. Este processo tem conotações simbólicas e é, por vezes, metáfora de actividades tipicamente masculinas. O produto - o tecido - tem em diversos casos um valor ritual. In many non-industrial societies, the transformation of raw material into cloth is woman’s work. Ability and skill in these activities give a woman prestige, in front of other women as well as in society in general. In this paper some of the techniques of spinning, weaving and dyeing, used in Asian societies, will be mentioned and described. In countries of Southeast Asia, weaving and cloth are closely connected to supernatural forces. The action of spiritual forces that help in the weaving process is well known. This process has symbolic connotations and at times is a metaphor of typically masculine activities. The product - the cloth - has in many cases a ritual value. info:eu-repo/semantics/publishedVersion

    Carrier Aggregation (CA) allows the network and User Equipment (UE) to aggregate carrier frequencies in licensed, unlicensed, or Shared Access (SA) bands of the same or different spectrum bands to boost the achieved data rates. This work aims to provide a detailed study on CA techniques for 5G New Radio (5G NR) networks while elaborating on CA deployment scenarios, CA-enabled 5G networks, and radio resource management and scheduling techniques. We analyze cross-carrier scheduling schemes in CA-enabled 5G networks for Downlink (DL) resource allocation. The requirements, challenges, and opportunities in allocating Resource Blocks (RBs) and Component Carriers (CCs) are addressed. The study and analysis of various multi-band scheduling techniques are made while maintaining that high throughput and reduced power usage must be achieved at the UE. Finally, we present CA as the critical enabler to advanced systems while discussing how it meets the demands and holds the potential to support beyond 5G networks, followed by discussing open issues in resource allocation and scheduling techniques. This work was supported by FCT/MCTES through national funds and, when applicable, cofounded EU funds under the project UIDB/50008/2020, ORCIP (22141-01/SAICT/2016), COST CA 20120 INTERACT, SNF Scientific Exchange - AISpectrum (project 205842) and TeamUp5G.

    With the increasing use of social networks, particularly Facebook, a large amount of data is made available. Such extensive and intensive disclosure of public and private matter aspects of individuals’ lives leads to theoretical and conceptual challenges. To answer some of these challenges, it is intended in this article, through the use of a qualitative methodology, to analyse the perceptions that Facebook users have of the surveillance they are subjected to, as well as the identification of prevention strategies that can be adopted. The interaction of these analysis dimensions has enabled the creation of a user typology that it is important, given the very recent nature of the object of this study, to confront and develop through new research. info:eu-repo/semantics/publishedVersion
