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 ...
Analytical, FEM and Experimental Study of the Influence of the Airgap Size in Different Types of Ferrite Cores
(IEEE, 2022)
This work reviews and compares different airgap reluctance calculation approaches with experimental results, focusing on the Schwarz-Christoffel transformation. The modelling of the airgap reluctance in two dimensions is ...
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 ...
Exploring the applicability of circular design criteria for electric vehicle batteries
(Elsevier, 2022)
Battery electric vehicles (BEVs) represent a promising solution to mitigate carbon emissions by road transportation. However, life cycle assessment (LCA) studies on BEVs have demonstrated that batteries are responsible for ...
Node-RED Workflow Manager for Edge Service Orchestration
(IEEE, 2022)
Microservice Architectures have increasingly become popular in Industry 4.0 as they allow heterogeneous systems to interact, reduce the complexity in the management of individual components, and support distributed ...
Towards the Isolation of Failure-Inducing Inputs in Cyber-Physical Systems: is Delta Debugging Enough?
(IEEE, 2022)
Cyber-Physical Systems (CPSs) combine digital cyber technologies with parallel physical processes. On the one hand, verification methods of such systems mostly rely on (system level) simulation-based testing. This technique ...
Impact performance of out of die UV cured pultruded profiles for vessel structures
(École Polytechnique Fédérale de Lausanne, 2022)
Out of die ultraviolet (UV) cured pultrusion is an automated process for manufacturing bent profiles that can replace the labour-intensive processes currently employed for manufacturing stiffeners for vessels structures. ...
Multi-Objective Metamorphic Test Case Selection: an Industrial Case Study (Practical Experience Report)
(IEEE, 2022)
Metamorphic testing is a technique that has shown great potential to alleviate the test oracle problem by exploiting the relations among the inputs and outputs of different executions of a system. However, this approach ...
