Reusability and Flexibility in Parametric Surface-based Models: A Review of Modelling Strategies
(Taylor and Francis Ltd., 2021)
CAD systems are indispensable tools in the product design and development process. Through the creation of parametric 3D models,they increase productivity, enable the design of highly complex parts, improve ...
Retinal thickness predicts the risk of cognitive decline in Parkinson's disease
(Wiley, 2021)
Objective: To analyze longitudinal changes of retinal thickness and their predictive value as biomarkers of disease progression in idiopathic Parkinson’s disease (iPD).
Methods: Patients with Lewy body diseases (LBDs) ...
A coupled 3D wear and fatigue numerical procedure: Application to fretting problems in ultra-high strength steel wires
(Elsevier Ltd., 2021)
This work presents a coupled 3D wear and fatigue numerical procedure for fretting problems in ultra-high strength steel wires that combines Archard’s wear equation with the Smith–Watson–Topper parameter to predict crack ...
An analytical approach to calculate stress concentration factors of machined surfaces
(Elsevier Ltd., 2021)
Machining operations affect the properties of the final surface layer, and these can impact on its functional per- formance, particularly on fatigue behaviour. Among the properties of the machined surface, surface topography ...
Power Balancing in Cascaded H-Bridge and Modular Multilevel Converters Under Unbalanced Operation: A Review
(IEEE, 2021)
Multilevel Voltage-Source Converters (VSC) based on modular structures are envisioned as a prominent alternative for grid and industry applications. Foremost among these are the Cascaded H-Bridge (CHB) and the Modular ...
Calendar Ageing Model for Li-Ion Batteries Using Transfer Learning Methods
(MDPI, 2021)
Getting accurate lifetime predictions for a particular cell chemistry remains a challenging process, largely dependent on time and cost-intensive experimental battery testing. This paper proposes a transfer learning (TL) ...
Novel High Accuracy Resolver Topology for Space Applications
(MDPI, 2021)
In recent years, the space industry has experienced a significant change mainly due to the incursion of private companies, which has shaken up the sector. This new situation allows for a reduction regarding the reliability ...
Application Dependent End-of-Life Threshold Definition Methodology for Batteries in Electric Vehicles
(MDPI, 2021)
The end-of-life event of the battery system of an electric vehicle is defined by a fixed end-oflife threshold value. However, this kind of end-of-life threshold does not capture the application and battery characteristics ...
Optimum Slot and Pole Design for Vibration Reduction in Permanent Magnet Synchronous Motors
(MDPI, 2021)
Permanent Magnet Synchronous Motors (PMSMs) are increasingly being used and are required to satisfy noise and vibration specifications. Thus, it is necessary to develop design guidelines for electric motors that consider ...
Dual Inertia-Emulation Control for Interlinking Converters in Grid-Tying Applications
(IEEE, 2021)
Electric grids are undergoing several changes, mostly driven by the replacement of classical highly-inertial generators by converter-interfaced generation and storage systems. This entails the reduction of inherent inertia ...
