Improvement of insulation effectiveness of natural rubber by adding hydroxyl-functionalized barium titanate nanoparticles
(2017-10-11)
Article
Open AccessNatural rubber (NR) products are being applied in many protective tools for life-line applications, including insulating boots, blankets, sleeves, insulating gloves, or flexible coverings. Due to the inherent risk of such ... -
Multivariable methods applied to FTIR: a powerful technique to highlight architectural changes in poly(lactic acid)
(Elsevier, 2018-02-01)
Article
Restricted access - publisher's policyThe structural modifications of a commercially available poly(lactid acid) grade were induced through reactive extrusion using a multi-epoxide reactive agent in a pilot plant. The statistical nature of the chemical reactions ... -
Chromatic monitoring of gear mechanical degradation based on acoustic emission
(Institute of Electrical and Electronics Engineers (IEEE), 2017-11-01)
Article
Open AccessThis paper presents a methodology for the feature estimation of a new fault indicator focused on detecting gear mechanical degradation under different operating conditions. Preprocessing of acoustic emission signal is ... -
Detection of eccentricity faults in five-phase ferrite-PM assisted synchronous reluctance machines
(Multidisciplinary Digital Publishing Institute, 2017-05-31)
Article
Open AccessAir gap eccentricity faults in five-phase ferrite-assisted synchronous reluctance motors (fPMa-SynRMs) tend to distort the magnetic flux in the air gap, which in turn affects the spectral content of both the stator currents ... -
Design and optimization for vehicle driving cycle of rare-earth-free SynRM based on coupled lumped thermal and magnetic networks
(2017-08-11)
Article
Restricted access - publisher's policyThis work presents a range optimization of a SynRM (synchronous reluctance motor) and a PMaSynRM (permanent-magnet-assisted synchronous reluctance motor) according to a standard driving cycle, and the solutions obtained ... -
Multimodal forecasting methodology applied to industrial process monitoring
(2017-09-20)
Article
Open AccessIEEE Industrial process modelling represents a key factor to allow the future generation of industrial manufacturing plants. In this regard, accurate models of critical signals need to be designed in order to forecast ... -
Dielectric response of vulcanized natural rubber containing BaTiO3 filler: the role of particle functionalization
(2017-12)
Article
Restricted access - publisher's policyNatural rubber (NR) nanocomposites have been prepared with hydroxylated barium titanate filler (BaTiO3-OH), employing emulsion polymerization followed by vulcanization process. The addition of barium titanate, a compound ... -
A 3D-FEM-based model to predict the electrical constriction resistance of compressed contacts
(2017-09-11)
Article
Restricted access - publisher's policyThis work proposes a method to estimate the electrical constriction resistance of two mating metallic rough surfaces based on the finite element method (FEM). The FEM-based method generates a random array of three-dimensional ... -
Influence of ZnO and TiO2 particle sizes in the mechanical and dielectric properties of vulcanized rubber
(2017-07-01)
Article
Open AccessThe novelty of the present study relies on the straightforward sonication of ZnO and TiO2 and incorporation to a complex formulation of latex, with other several organic-inorganic additives that influences the cross-linking ... -
