A Machine Learning approach for the validation and optimization of permittivity mixing rules for binary liquids
(Universidad de Extremadura; Union Radio-Scientifique Internationale (Cáceres, España), 2023-12-31)This paper presents the application of Support Vector Regressor models trained with glycerin-water mixture signals from a Dielectric Resonator sensor. Each signal is labeled with a concentration considered. The performance ... -
A machine learning method applied to the evaluation of the condition in a fleet of similar vehicles
(European Safety and Reliability Association; International Association for Probabilistic Safety Asse (Venecia, Italia), 2020-11-01)This paper presents a procedure for anomaly detection of temperatures in different key components of the power train in a fleet of similar vehicles. The anomaly detection is based on the characterization of the typical ... -
A medium-term operation model for a natural gas system
(Sin editorial (Zagreb, Croacia), 2011-05-25)During last decades, consumption of natural gas has been continuously increasing worldwide. Hence, infrastructure has been developed to transport the natural gas from the well to the final consumer. Natural gas chain value ... -
A method for estimating stress of a failure mode in a component due to abnormal behaviour observed in a wind turbine
(Det Norske Veritas, Norway and Centre for Industrial Asset Management (CIAM), University of Stavange (Stavanger, Noruega), 2011-05-30)Sometimes an industrial component can be affected during its life by several external and internal conditions that can induce failure modes, or at least, contribute to the presence of one or more symptoms ... -
