A robust islanding detection method with zero-non-detection zone for distribution systems with DG
(2021-12-01)
Article
Open AccessThis paper proposes a strategy for detecting unintentional islanding operations (IOs) in distribution networks (DNs) with distributed generation (DG), which eliminating the non-detection zone (NDZ). This hybrid method ... -
Understanding imprint formation, plastic instabilities and hardness evolutions in FCC, BCC and HCP metal surfaces
(2021-09)
Article
Open AccessNanoindentation experiments in metal surfaces are characterized by the onset of plastic instabilities along with the development of permanent nanoimprints and dense defect networks. This investigation concerns massive ... -
Statistics of dislocation avalanches in FCC and BCC metals: dislocation mechanisms and mean swept distances across microsample sizes and temperatures
(Nature, 2020-12-01)
Article
Open AccessPlastic deformation in crystalline materials consists of an ensemble of collective dislocation glide processes, which lead to strain burst emissions in micro-scale samples. To unravel the combined role of crystalline ... -

Article
Restricted access - publisher's policyThe Electrical Engineering department of the University FNB/UPC -Barcelona Tech. conducted a large set of real tests on a hybrid propulsion platform with compressed natural gas (CNG) fuel at the facilities of Marina Barcelona ... -
Finite element analysis of narrow dental implants
(2020-07-08)
Article
Open AccessNarrow-diameter implants (NDIs) traditionally have been associated to higher rates of failure in comparison with regular-diameter implants (RDIs) and wide-diameter implants (WDIs), since they generate a more unfavorable ... -
Grasp: design and preliminary testing of an open-source, 3D printable bionic hand
(2020-02-03)
Article
Open AccessWe present the design and performance evaluation of a 3D printable bionic hand developed to be manufactured, assembled and programmed in the simplest way by the user. This prosthetic device can be controlled by surface ... -
Assessment of unintentional islanding operations in distribution networks with large induction motors
(2020-01-10)
Article
Open AccessThis paper is aimed at assessing the impact of unintentional islanding operations (IOs) in the presence of large induction motors (IMs) within distribution networks (DNs). When a fault occurs,followingthecircuitbreaker(C ... -
A novel voltage sag approach during unintentional islanding scenarios: A survey from real recorded events
(2019-07)
Article
Open AccessIn this paper, a new voltage sag approach is analytically modelled and validated using both simulation and field measurements. The main aspect of this approach is to propose a new voltage sag feature which appears during ... -
Power quality disturbances assessment during unintentional islanding scenarios. A contribution to voltage sag studies
(2019-08-20)
Article
Open AccessThis paper presents a novel voltage sag topology that occurs during an unintentional islanding operation (IO) within a distribution network (DN) due to large induction motors (IMs). When a fault occurs, following the circuit ... -
Synthetic open cell foams versus a healthy human vertebra: Anisotropy, fluid flow and µ-CT structural studies
(Elsevier, 2020-03-11)
Article
Open AccessCommercial synthetic open-cell foams are an alternative to human cadaveric bone to simulate in vitro different scenarios of bone infiltration properties. Unfortunately, these artificial foams do not reproduce the anisotropic ... -
Analysis of bone cement distribution around fenestrated pedicle screws in low bone quality lumbosacral vertebrae
