Effects of manufacturing tolerances of permanent magnets in fractional slot permanent magnet synchronous machines
(IET, 2019)The fractional slot permanent magnet synchronous machines are well-known for their low torque ripple. However, in mass-production machines, not all the permanent magnets are identical due to the manufacturing tolerances ... -
Hardware-in-the-loop performance analysis of a railway traction system under sensor faults
(IET, 2019)Fault mode and effects analysis (FMEA) has been used during decades for analysing the effects of faults in different applications. Initially, FMEA based on risk priority numbers provided information about the effects in ... -
Surface integrity of additive manufacturing parts: a comparison between optical topography measuring techniques
(Elsevier B.V., 2020)Additive Manufacturing (AM) presents significant industry-specific advantages allowing the creation of complex geometries and internal features that cannot be produced using conventional manufacturing processes. However, ... -
Neuro-Sliding Control for Underwater ROV’s Subject to Unknown Disturbances
(MDPI, 2019)Proposed in this paper is a model-free and chattering-free second order sliding mode control(2nd-SMC) in combination with a backpropagation neural network (BP-NN) control scheme for underwater vehicles to deal with external ... -
Modelling of an Additive 3D-Printing Process Based on Design of Experiments Methodology
(Technical University of Kosice, Slovakia, 2020)Purpose: The implementation of additive manufacturing (AM) or 3D-printer manufacturing for technical prototyping, preproduction series and short production series can bring benefits in terms of reducing cost and time to ... -
On the Role of a ZDDP in the Tribological Performance of Femtosecond Laser-Induced Periodic Surface Structures on Titanium Alloy against Different Counterbody Materials
(MDPI, 2019)Laser-induced periodic surface structures (LIPSS, ripples) with ~500–700 nm period were produced on titanium alloy (Ti6Al4V) surfaces upon scan processing in air by a Ti:sapphire femtosecond laser. The tribological ... -
Modelling and Resolution of Dynamic Reliability Problems by the Coupling of Simulink and the Stochastic Hybrid Fault Tree Object Oriented (SHyFTOO) Library
(MDPI, 2019)Dependability assessment is one of the most important activities for the analysis of complex systems. Classical analysis techniques of safety, risk, and dependability, like Fault Tree Analysis or Reliability Block Diagrams, ... -
Design of a Solid-State Circuit Breaker for a DC Grid-Based Vessel Power System
(MDPI, 2019)Electric propulsion and integrated hybrid power systems can improve the energy efficiency and fuel consumption of different kinds of vessels. If the vessel power system is based on DC grid distribution, some benefits ... -
Partial state-of-charge mitigation in standalone photovoltaic hybrid storage systems
(MPDI, 2019)Energy Storage in photovoltaic installations has increased in popularity in recent years due to the improvement in solar panel technology and energy storage systems. In several places where the grid is not available, in ... -
Recycling in Babel: The Impact of Foreign Languages in Rule Learning
(MDPI, 2020-05-27)Environmental decisions and prosocial behaviors have been shown to be emotionally mediated, and language is at the core of emotions. The language context can alter the way decisions are made, and using a foreign language ... -
MODDALS Methodology for Designing Layered Ontology Structures
(IOS Press, 2020)Global ontologies include common vocabularies to provide interoperability among different applications. These ontologies require a balance of reusability-usability to minimise the ontology reuse effort in different ... -
Monitoring of a Hammer Forging Testing Machine for High-Speed Material Characterization
(Elsevier Ltd., 2020)Dynamic testing of materials is necessary to model high-speed forming processes (i.e. hammer forging, blanking) and crash/impact behavior of structures, among others. The most common machines to perform medium to high-speed ... -
The influence of the kinematic hardening on the FEM simulation of Tension Levelling Process
(Elsevier Ltd., 2020)Tension levelling is used in the steel industry to remove shape defects present in cold rolled strip. This technology is increasingly being employed by steel makers to level AHSS steels, because conventional roll levelers ... -
DABGEO: a Reusable and Usable Global Energy Ontology for the Energy Domain
(Elsevier B.V.Ontology usability, 2020)The heterogeneity of energy ontologies hinders the interoperability between ontology-based energymanagement applications to perform a large-scale energy management. Thus, there is the need fora global ontology that provides ... -
