Accurate long-term air temperature prediction with Machine Learning models and data reduction techniques
(Elsevier, 2023-03)
In this paper, three customised Artificial Intelligence (AI) frameworks, considering Deep Learning, Machine Learning (ML) algorithms and data reduction techniques, are proposed for a problem of long-term summer air temperature ...
Special Issue on Applications of Speech and Language Technologies in Healthcare
(MDPI, 2023-06-05)
In recent years, the exploration and uptake of digital health technologies have advanced rapidly with a real potential impact to revolutionise healthcare delivery and associated industries [...]
Statistical relationship between RMS and QP spectra of voltage measurements in the 9–150 kHz range
(Elsevier, 2023-05)
The main objective of this work is to obtain an empirical relationship between the root-mean-square and the quasi-peak spectra of voltage recordings in the electrical grid, based on a statistical analysis of a set of ...
Fabrication and characterization of active polymer optical fibers with a ring-doped structure
(Elsevier, 2023-01)
This paper employs the solution-doping technique for the fabrication of polymer optical fibers (POFs) doped with two perylene derivatives, Lumogen Yellow 083 and Lumogen Red 305, in different combinations. With the ...
Frame-Based Phone Classification Using EMG Signals
(MDPI, 2023-06-30)
This paper evaluates the impact of inter-speaker and inter-session variability on the development of a silent speech interface (SSI) based on electromyographic (EMG) signals from the facial muscles. The final goal of the ...
NoisenseDB: An Urban Sound Event Database to Develop Neural Classification Systems for Noise-Monitoring Applications
(MDPI, 2023-08-17)
The use of continuous monitoring systems to control aspects such as noise pollution has grown in recent years. The commercial monitoring systems used to date only provide information on noise levels but do not identify the ...
On the suitability of the CISPR 16 method for measuring conducted emissions in the 2–150kHz range in low voltage grids
(Elsevier, 2023-03)
The IEC 61000–2–2 standard defines the compatibility levels to evaluate the conducted disturbances in the low voltage grid for the 2-150 kHz range. For frequencies 9–150 kHz, they are defined in terms of quasi peak values ...
Deep learning for understanding multilabel imbalanced Chest X-ray datasets
(Elsevier, 2023-07)
Over the last few years, convolutional neural networks (CNNs) have dominated the field of computer vision thanks to their ability to extract features and their outstanding performance in classification problems, for example ...
Trustworthy Users: Using IOTA and IPFS for Attribute Validation in CP-ABE and dCP-ABE Schemes
(MDPI, 2023-03-10)
Attribute spoofing is a major security threat in information exchange solutions based on Ciphertext-Policy Attribute-Based-Encryption (CP-ABE) and distributed CP-ABE (dCP-ABE), which can compromise privacy and security. ...
Modeling a Linux Packet-Capturing System with a Queueing System with Vacations
(MDPI, 2023-03-30)
Monitoring the evolution of the state of networks is an important issue to ensure that many applications provide the required quality of service. The first step in network-monitoring systems consists of capturing packets; ...
