Current References Limitation Method Considering Voltage and Current Maximums for STATCOMs Providing Simultaneously Reactive Power and Current Harmonics
(IEEE, 2022)
This article focuses the analysis on a static synchronous compensator (STATCOM) that operates simultaneously providing reactive power and several current harmonics of different frequencies (active power filter or active ...
Effect of surface integrity generated by machining on isothermal low cycle fatigue performance of Inconel 718
(Elsevier Ltd., 2022)
Critical aero-engine components such as turbine discs must withstand severe cyclic stresses, which can eventually lead to low cycle fatigue (LCF) failures. These components are made of difficult-to-cut alloys and machining ...
A data-driven long-term metocean data forecasting approach for the design of marine renewable energy systems
(Elsevier, 2022)
The potential of Marine Renewable Energy (MRE) systems is usually evaluated based on recent metocean data and assuming the stationarity of the MRE resource. Yet, different studies in the literature have shown long-term ...
Numerical analysis of AISI 321 alloy material parameters on rubber pad diaphragm forming
(IOP Publishing, 2022)
Rubber pad diaphragm forming is a technology that uses a rigid die in conjunction with a flexible polyurethane tool and fluid pressure action in order to shape metal sheets. In this process, the action of the fluid forms ...
Time-Frequency Analysis of Experimental Measurements for the Determination of EMI Noise Generators in Power Converters
(MDPI, 2022)
In the context of recent decades in which there has been great development in power electronics systems with increasingly better operating characteristics, the study of the factors that affect the behaviour of these systems ...
Surface integrity evaluation within dry grinding process on automotive gears
(Elsevier B.V., 2022)
Gears are essential components in automotive transmissions and their performance directly depends on the flanks surface integrity. To date the gears whole production chain do not use lubricants, except the final step of ...
Fibre-Wood Laminate Biocomposites: Seawater Immersion Effects on Flexural and Low Energy Impact Properties
(MDPI, 2022)
The present paper explores a new concept of a hybrid eco-composite by substituting the natural fibre plies with thin wood veneers. The new composite, named Fibre–Wood Laminate (FWL), is inspired by fibre–metal laminate ...
Experimental assessment of scale-effects on the aerodynamic characterization of a transitionally-operating airfoil working under clean flow conditionsExperimental assessment of scale-effects on the aerodynamic characterisation of a transitionally-operating airfoil working under clean flow conditions
(Elsevier, 2022)
Wind tunnel tests are carried out upon a NACA0021 airfoil subjected to transitional Reynolds numbers. Transitionally-operating airfoils show a high sensitivity to external conditions and pose relevant measurement issues ...
Synthetic Subject Generation with Coupled Coherent Time Series Data †
(MDPI, 2022)
A large amount of health and well-being data is collected daily, but little of it reaches its research potential because personal data privacy needs to be protected as an individual’s right, as reflected in the data ...
Effect of Tool Geometry and LCO2 Cooling on Cutting Forces and Delamination when Drilling CFRP Composites Using PCD Tools
(Elsevier, 2022)
Lightweight materials like Carbon Fiber Reinforced Polymers (CFRPs) present certain challenges, mainly regarding the resultant surface integrity of the holes. Different techniques such as optimized tool geometries, machining ...
