Context-Aware Policy Analysis for Distributed Usage Control
(MDPI, 2022-09-27)
To boost data spaces and benefit from the great opportunities that they present, data sovereignty must be provided by Distributed Usage Control (DUC). Assuming that DUC will be managed by implementing and enforcing policies, ...
Twin-core fiber sensor integrated in laser cavity
(Nature, 2022)
In this work, we report on a twin-core fiber sensor system that provides improved spectral efficiency, allows for multiplexing and gives low level of crosstalk. Pieces of the referred strongly coupled multicore fiber are ...
Analysis of NOMA-Based Retransmission Schemes for Factory Automation Applications
(IEEE-Institute of Electrical and Electronics Engineers, 2021-02-12)
New use cases and applications in factory automation scenarios impose demanding requirements for traditional industrial communications. In particular, latency and reliability are considered as some of the most representative ...
Geometric optics analysis of inverted graded index fibers
(IOP, 2022)
We derive a general solution based on geometric optics that describes the light propagation properties in multimode optical fibers with inverted refractive index profiles. Using this general solution, we classify rays ...
Continuous Quantitative Risk Management in Smart Grids Using Attack Defense Trees
(MDPI, 2020-08-07)
Although the risk assessment discipline has been studied from long ago as a means to support security investment decision-making, no holistic approach exists to continuously and quantitatively analyze cyber risks in scenarios ...
POF-Based Solar Concentrators Incorporating Dyes and Europium Chelates
(MDPI, 2021-05-19)
In this paper, useful models that enable time-efficient computational analyses of the performance of luminescent solar concentrators (LSCs) are developed and thoroughly described. These LSCs are based on polymer optical ...
Effects of Fabrication Methods on the Performance of Luminescent Solar Concentrators Based on Doped Polymer Optical Fibers
(MDPI, 2021-01-28)
In this work, we detail two types of fabrication processes of four polymer optical fibers doped with lumogen dyes. The fiber preforms have been manufactured with two different methods: extrusion and casting. We have compared ...
Towards the Prediction of Rearrest during Out-of-Hospital Cardiac Arrest
(MDPI, 2020-07-09)
A secondary arrest is frequent in patients that recover spontaneous circulation after an out-of-hospital cardiac arrest (OHCA). Rearrest events are associated to worse patient outcomes, but little is known on the heart ...
A prescription of methodological guidelines for comparing bio-inspired optimization algorithms
(Elsevier, 2021-12)
[EN]Bio-inspired optimization (including Evolutionary Computation and Swarm Intelligence) is a growing research topic with many competitive bio-inspired algorithms being proposed every year. In such an active area, preparing ...
Upgrading the Power Grid Functionalities with Broadband Power Line Communications: Basis, Applications, Current Trends and Challenges
(MDPI, 2022)
This article reviews the basis and the main aspects of the recent evolution of Broadband Power Line Communications (BB-PLC or, more commonly, BPL) technologies. The article starts describing the organizations and alliances ...
