Sensitivity-optimized strongly coupled multicore fiber-based thermometer
(Elsevier, 2022-01)
[EN] In this paper, we report on a multicore fiber-based (MCF) temperature sensor that operates in a wide thermal range and that is robustly packaged to withstand harsh environments. To develop the sensor, the fundamentals ...
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 ...
On the Analysis of Speech and Disfluencies for Automatic Detection of Mild Cognitive Impairment
(Springer, 2020-10)
Alzheimer's disease is characterized by a progressive and irreversible cognitive deterioration. In a previous stage, the so-called Mild Cognitive Impairment or cognitive loss appears. Nevertheless, this previous stage does ...
Optimized CFD modelling and validation of radiation section of an industrial top-fired steam methane reforming furnace
(Elsevier, 2021-12)
[EN]The present study proposes an optimized computational fluid dynamics (CFD) modelling framework to provide a complete and accurate representation of combustion and heat transfer phenomena in the radiation section of an ...
Fine-tune of lignin properties by its fractionation with a sequential organic solvent extraction
(Elsevier, 2022-01)
[EN] In this work, different lignins were obtained from two different extraction methods (kraft and organosolv) but from the same raw material (Eucalyptus globulus sp.). They were subsequently fractionated to determine the ...
Bayesian network-based over-sampling method (BOSME) with application to indirect cost-sensitive learning
(Nature, 2022-05)
Traditional supervised learning algorithms do not satisfactorily solve the classification problem on imbalanced data sets, since they tend to assign the majority class, to the detriment of the minority class classification. ...
Do jumps and cojumps matter for electricity price forecasting? Evidence from the German-Austrian day-ahead market
(Elsevier, 2022-11)
This paper analyzes the potential for including jumps and cojumps in electricity price forecasting models. The study is carried out on the German-Austrian day-ahead electricity market with a multivariate framework in which ...
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 ...
Life Cycle Assessment of various biorefinery approaches for the valorisation of almond shells
(Elsevier, 2021-10)
In the near future, sustainable and efficient biorefineries would be essential for the production of commodity chemicals and high-added value compounds. Therefore, in this work, six scenarios differing on the delignification ...
