Active Power Optimization of a Turning Process by Cutting Conditions Selection: A Q-Learning Approach
(IEEE, 2022)
In the context of Industry 4.0, the optimization of manufacturing processes is a challenge. Although in recent years many of the efforts have been in this direction, there is still improvement opportunities in these ...
On the Cost-Effectiveness of Composite Metamorphic Relations for Testing Deep Learning Systems
(IEEE, 2022)
Deep Learning (DL) components are increasing their presence in mission and safety-critical systems, such as autonomous vehicles. The verification process of such systems needs to be rigorous, for which automated solutions ...
Towards Standardized Manufacturing as a Service through Asset Administration Shell and International Data Spaces Connectors
(IEEE, 2022)
This paper presents an industrial scenario that simulates a Manufacturing as a Service system for the execution of remote production orders built upon the implementation of emerging Asset Administration Shell (AAS) ...
Influence of manufacturing tolerances and eccentricities on the unbalanced magnetic pull in permanent magnet synchronous motors
(IEEE, 2020)
Eccentricity is an inevitable fault in electric motors and hence its diagnosis is an important topic. Thus, the influence of static and dynamic eccentricities on the harmonics of the frequency spectra of the unbalanced ...
Influence of Manufacturing Tolerances and Eccentricities on the Electromotive Force in Permanent Magnet Synchronous Motors
(IEEE, 2022)
Eccentricity is a common error in electric motors, so its diagnosis is an important issue. Therefore, the effect of static and dynamic eccentricities on the harmonics of the frequency spectra of the voltage of a phase is ...
Dynamic Wireless Power Transfer DWPT Time Domain model: xyz position and speed coupling effect
(IEEE, 2022)
The paper presents a DWPT system time domain model which considers speed and position (x, y, z) coupling effects. The speed effect compared to static WPT, presents an active behavior that should be considered during the ...
Benefits of switching from Si to SiC modules with further converter optimization
(IEEE, 2022)
SiC semiconductors have better characteristics than Si, improving power electronics converters performances. A prototype that can switch semiconductor technology without changing any other part of the system is built and ...
Evolutionary generation of metamorphic relations for cyber-physical systems
(ACM, 2022)
A problem when testing Cyber-Physical Systems (CPS) is the difficulty of determining whether a particular system output or behaviour is correct or not. Metamorphic testing alleviates such a problem by reasoning on the ...
A Dynamic Frequency-and-Voltage Power Flow Simulation Tool for Hybrid AC/DC Power Systems based on Simulink
(IEEE, 2022)
A more renewable energy generation model entails the replacement of synchronous generator-based power plants by converter-interfaced renewable sources, resulting in more susceptible power systems in terms of frequency and ...
Identification and Prioritisation of Professional Transitions in Manufacturing Operations in the New Context of Industry 4.0
(Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2023)
This paper examines the results from the identification and prioritisation phase of professional transitions towards the requalification of digital job operators. It was developed as part of the ‘Learning Solutions for ...
