A method for the controllable fabrication of optical fiber-based localized surface plasmon resonance sensors
(Nature, 2022)
[EN] Optical fiber-based Localized Surface Plasmon Resonance (OF-LSPR) biosensors have emerged as an ultra-sensitive miniaturized tool for a great variety of applications. Their fabrication by the chemical immobilization ...
Multi-parameter optical gauge based on mode coupling effect in asymmetric index multi-core fibres
(Elsevier, 2022-07)
An optical gauge based on coupled multi-core fiber is proposed and experimentally demonstrated. By using direct laser writing to selectively break the fiber index profile symmetry, asymmetric mode coupling between cores ...
Swin transformer for fast MRI
(Elsevier, 2022-07)
Magnetic resonance imaging (MRI) is an important non-invasive clinical tool that can produce high -resolution and reproducible images. However, a long scanning time is required for high-quality MR images, which leads to ...
Contribuciones de inteligencia artificial aplicada en sistemas industriales
(2022-05-26)
La dinámica de la sociedad moderna empuja al sector industrial hacia una creciente necesidad de sistemas cada vez más complejos y autónomos, destinada a liberar a los seres humanos de tareas mecánicas, repetitivas y poco ...
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, ...
Contribution to the uptake of Cloud Computing solutions: Design of a cloud services intermediator to foster an ecosystem of trusted, interoperable and legal compliant cloud services. Application to multi-cloud aware software
(2022-10-05)
El objetivo del trabajo de investigación presentado en esta tesis es facilitar a los desarrolladores y operadores de aplicaciones desplegadas en múltiples Nubes el descubrimiento y la gestión de los diferentes servicios ...
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 ...
