Effect of electron number densities on the radio signal propagation in an inductively coupled plasma facility
(2023-11)
Article
Open AccessSpacecraft entering a planetary atmosphere are surrounded by a plasma layer containing high levels of ionization, due to the extreme temperatures in the shock layer. The high electron number densities cause attenuation of ... -
Prediction models using artificial intelligence and longitudinal data from electronic health records: a systematic methodological review
(2023-09-02)
Article
Open AccessObjective: To describe and appraise the use of artificial intelligence (AI) techniques that can cope with longitudinal data from electronic health records (EHRs) to predict health-related outcomes. Methods: This ... -
Satellite edge computing for real-time and very-high resolution Earth observation
(2023-07-18)
Article
Open AccessIn high-resolution Earth observation imagery, Low Earth Orbit (LEO) satellites capture and transmit images to ground to create an updated map of an area of interest. Such maps provide valuable information for meteorology ... -
Lens based switched beam antenna for a 5G smart repeater
(2023)
Article
Open AccessA 16 switched beam lens based antenna with a coverage area of ±30° in the horizontal plane and from 0 to -20° in the vertical plane has been built and tested. The intended use of the antenna is as part of a smart repeater ... -
Dielectric resonator to measure surface resistance of accelerator components at room temperature and 77 K
(American Physical Society (APS), 2023-08)
Article
Open AccessWe measured the surface resistance of titanium, amorphous carbon, and nonevaporable getter (NEG) coatings on copper samples, representative of surface treatments of beam-facing components in the High-Luminosity Large Hadron ... -
Gradient-based metrics for the evaluation of image defogging
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-09-09)
Article
Open AccessFog, haze, or smoke are standard atmospheric phenomena that dramatically compromise the overall visibility of any scene, critically affecting features such as the illumination, contrast, and contour detection of objects. ... -
Optimizing access demand for mMTC traffic using neural networks
(Institute of Electrical and Electronics Engineers (IEEE), 2023-07-12)
Article
Open AccessMachine-type communications show unique spatial and temporal correlation properties that often lead to bursty access demand profiles. With the expected large-scale deployment of the Internet of Things (IoT), next-generation ... -
Quantum-inspired protocol for measuring the degree of similarity between spatial shapes
(2022-11)
Article
Open AccessWe put forward and demonstrate experimentally a quantum-inspired protocol that allows us to quantify the degree of similarity between two spatial shapes embedded in two optical beams without the need to measure the amplitude ... -
A tutorial on the characterisation and modelling of low layer functional splits for flexible radio access networks in 5G and beyond
(Institute of Electrical and Electronics Engineers (IEEE), 2023-07-19)
Article
Open AccessThe centralization of baseband (BB) functions in a radio access network (RAN) towards data processing centres is receiving increasing interest as it enables the exploitation of resource pooling and statistical multiplexing ... -
Multiqubit time-varying quantum channels for NISQ-era superconducting quantum processors
(American Physical Society, 2023-07)
Article
Open AccessTime-varying quantum channels (TVQCs) have been proposed as a model to include fluctuations of the relaxation (T1) and dephasing times (T2). In previous works, realizations of multiqubit TVQCs have been assumed to be equal ... -
Contribution of frailty to multimorbidity patterns and trajectories: Longitudinal dynamic cohort study of aging people
(2023-06-27)
Article
Open AccessBackground: Multimorbidity and frailty are characteristics of aging that need individualized evaluation, and there is a 2-way causal relationship between them. Thus, considering frailty in analyses of multimorbidity is ... -
Quantifying bypass traffic in partially meshed transparent optical networks
(Springer Nature, 2023-06-28)
Article
Open AccessThis work investigates the transparent bypassing capacity requirements of elastic backbone optical networks to determine the all-optical cross-connection capacity needed at network nodes. Topological parameters have been ...
