A novel formulation for radial fretting wear: Application to false brinelling in thrust bearings
(Elsevier Ltd., 2021)
Radial fretting is defined as the damage caused by the relative motion of a ball under a variable normal load. The conducted experimental tests proved the existence of this damage even in contacting bodies with similar ...
Deep learning models for predictive maintenance: a survey, comparison, challenges and prospects
(Springer Science+Business Media, LLC, 2022)
Given the growing amount of industrial data in the 4th industrial revolution, deep learning solutions have become popular for predictive maintenance (PdM) tasks, which involve monitoring assets to anticipate their requirements ...
Demystifying Non-Isolated DC–DC Topologies on Partial Power Processing Architectures
(MDPI, 2022)
This paper discusses the possibility of achieving partial power processing with non-isolated DC–DC topologies. To this end, partial power converter architectures are seen as an interesting solution for reducing the power ...
Analytical Model to Calculate Radial Forces in Permanent-Magnet Synchronous Machines
(MDPI, 2021)
There are three principal sources of noise and vibration in electrical machines: electromagnetic sources, mechanical sources, and aerodynamic sources. Nowadays, one of the major advantages of permanent-magnet synchronous ...
Substitutive Press-Bolster and Press-Ram Models for the Virtual Estimation of Stamping-Tool Cambering
(MDPI, 2021)
Today’s stamping simulations are realized by ignoring the elastic deformation of the press and tooling system through the assumption of a rigid behavior and a perfect press stroke. However, in reality, the press and tool ...
Employee Perceptions About Participation in Decision-Making in the COVID Era and Its Impact on the Psychological Outcomes: A Case Study of a Cooperative in MONDRAGON (Basque Country, Spain)
(Frontiers, 2022)
This research aims to study possible effects or impacts of COVID-19 in the context of a democratic organizational system analyzing how COVID-19 has influenced employees’ perception of their participation in decision-making ...
Giza eta gizarte-zientziak eta irakasleen Prestakuntzarako unibertsitate-masterra: paradigma epistemologikoa
(2021)
Humanitate eta Gizarte Zientzien arloko Irakasleak Prestatzeko Masterra egiten ari di-ren ikasleek gizarteaz eta gizarteak irakaskuntzari buruz duen ikuspegiaz gogoeta egin behar luketela iri-tzita, eta, ...
Wind Turbine Oriented Solutions to Improve Power Quality and Harmonic Compliance of AC Offshore Wind Power Plants
(IEEE, 2021)
The operation of offshore wind power plants with respect to power quality and grid code compliance must be verified for different conditions in the design phase using harmonic analysis methods. This paper addresses this ...
Getting fair institutional conditions for district heating consumers: Insights from Denmark and Sweden
(Elsevier Ltd., 2021)
District heating is expected to play an important role in the EU for the implementation of a low carbon energy system with high shares of renewables. Empirical examples from several countries show that district heating ...
A new equivalent circuit model parametrization methodology based on current pulse tests for different battery technologies
(MDPI, 2021)
With growing global commitment to renewable energy generation, the role of energy storage systems has become a central issue in traction power applications, such as electric vehicles, trains, and elevators. To achieve the ...
