Article
Open AccessArtificial intelligence has bounced into industrial applications contributing several advantages to the field and have led to the possibility to open new ways to solve many actual problems. In this paper, a data-driven ... -
Fuzzy logic controller parameter optimization using metaheuristic Cuckoo search algorithm for a magnetic levitation system
(Multidisciplinary Digital Publishing Institute, 2019-06-16)
Article
Open AccessThe main benefits of fuzzy logic control (FLC) allow a qualitative knowledge of the desired system’s behavior to be included as IF-THEN linguistic rules for the control of dynamical systems where either an analytic model ... -
LISA Pathfinder platform stability and drag-free performance
(American Physical Society (APS), 2019-04-15)
Article
Open AccessThe science operations of the LISA Pathfinder mission have demonstrated the feasibility of sub-femto-g free fall of macroscopic test masses necessary to build a gravitational wave observatory in space such as LISA. While ... -
Driver drowsiness detection based on respiratory signal analysis
(Institute of Electrical and Electronics Engineers (IEEE), 2019-06-24)
Article
Open AccessDrowsy driving is a prevalent and serious public health issue that deserves attention. Recent studies estimate around 20% of car crashes have been caused by drowsy drivers. Nowadays, one of the main goals in the development ... -
Performance analysis of acoustic emission hit detection methods using time features
(Institute of Electrical and Electronics Engineers (IEEE), 2019-05-27)
Article
Open AccessAcoustic emission (AE) analysis is a powerful potential characterisation method forfracture mechanism analysis during metallic specimen testing. Nevertheless, identifying and extracting each event when analysing ... -
Analysis and mitigation of stray capacitance effects in resistive high-voltage dividers
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-06-14)
Article
Open AccessThis work analyzes the effects of the parasitic or stray distributed capacitance to ground in high-voltage environments and assesses the effectiveness of different corrective actions to minimize such effects. To this ... -
Parameter-independent battery control based on series and parallel impedance emulation
(Institute of Electrical and Electronics Engineers (IEEE), 2019-05-29)
Article
Open AccessAppropriate voltage control is essential in order to extend the useful life of a battery. However, when universal chargers are used, the design of this control becomes more complicated, given the fact that the battery ... -
Forbush decreases and <2 day GCR flux non-recurrent variations studied with LISA pathfinder
(Institute of Physics (IOP), 2019-04-01)
Article
Open AccessNon-recurrent short-term variations of the galactic cosmic-ray (GCR) flux above 70 MeV n-1 were observed between 2016 February 18 and 2017 July 3 on board the European Space Agency LISA Pathfinder (LPF) mission orbiting ... -
Wearable high-performance meander ring dipole antenna for electronic-textile applications
(2019-06-17)
Article
Restricted access - publisher's policyA novel wearable dipole antenna at 325¿MHz resonance frequency is presented in this article. A felt fabric with permittivity 1.2 and thickness 0.7¿mm is used as a substrate. The proposed design is validated by comparison ... -

(2019-08-20)
Article
Restricted access - publisher's policyThe market penetration of Plug-in Electric Vehicles (PEVs) is escalating due to their energy saving and environmental benefits. In order to address PEVs impact on the electric networks, the aggregators need to accurately ... -
Antennas based on low-cost thermoplastic polymer substrates for communication in the industrial, scientific and medical radio band
(2019-05-10)
Article
Open AccessThis work addresses the design guidelines, manufacturing process and experimental test of several antennas based on low cost and low loss thermoplastic polymer substrates. The proposed antennas are based on patch topologies ... -
Action potential propagation: ion current or intramembrane electric field?
(2018-01-22)
Article
Open AccessThe established action potential propagation mechanisms do not satisfactorily explain propagation on myelinated axons given the current knowledge of biological channels and membranes. The flow across ion channels presents ...
