Friction Modelling for Tube Hydroforming Processes : A Numerical and Experimental Study with Different Viscosity Lubricants
(MDPI, 2022)
The final quality of sheet and tube metal–formed components strongly depends on the tribology and friction conditions between the tools and the material to be formed. Furthermore, it has been recently demonstrated that ...
Lessons, narratives, and research directions for a sustainable circular economy
(Wiley, 2022)
The current enthusiasm for the circular economy (CE) offers a unique opportunity to advance the impact of research on sustainability transitions. Diverse interpretations of CE by scholars, however, produce partly opposing ...
Spatial characterization of the effect of age and sex on macular layer thicknesses and foveal pit morphology
(PLoS, 2022)
Characterizing the effect of age and sex on macular retinal layer thicknesses and foveal pit morphology is crucial to differentiating between natural and disease-related changes. We applied advanced image analysis techniques ...
Improving surface integrity when drilling CFRPs and Ti-6Al-4V using sustainable lubricated liquid carbon dioxide
(Elsevier, 2022)
In the quest for decreasing fuel consumption and resulting gas emissions in the aeronautic sector, lightweight materials such as Carbon Fiber Reinforced Polymers (CFRPs) and Ti-6Al-4V alloys are being used. These materials, ...
Design Space Analysis of the Dual-Active-Bridge Converter for More Electric Aircraft
(MDPI, 2022)
In the literature, different DC/DC power electronic converters (PECs) have been found to interconnect high-voltage DC and low-voltage DC grids in the electric power distribution networks of aircraft. In this scenario, the ...
Development and validation of a tool for the integration of the circular economy in industrial companies
(Elsevier, 2022)
Circular Economy (CE) implementation is considered an instrumental strategy to help reaching the world's resource, energy, and climate mitigation targets, including the Sustainable Development Goals (SDGs) 2030. However, ...
Context-awareness for the design of Smart-product service systems: Literature review
(Elsevier, 2022)
Smart-Product Service Systems (S-PSS) emerge as a novel strategy to integrate smart products with advanced digital capabilities and their related e-services to satisfy user’s needs in highly context-dependent environments. ...
Heart-brain synchronization breakdown in Parkinson’s disease
(Springer Nature, 2022)
Heart rate variability (HRV) abnormalities are potential early biomarkers in Parkinson’s disease (PD) but their relationship with central autonomic network (CAN) activity is not fully understood. We analyzed the synchronization ...
Hybrid Transformer Prognostics Framework for Enhanced Probabilistic Predictions in Renewable Energy Applications
(IEEE, 2022)
The intermittent nature of renewable energy sources (RESs) hamper their integration to the grid. The stochastic and rapid-changing operation of RES technologies impact on power equipment reliability. Transformers are key ...
A post-processing technique for removing ‘irregular frequencies’ and other issues in the results from BEM solvers
(European Wave and Tidal Energy Conference, 2022)
Within the wave energy community, hydrodynamic coefficients obtained from boundary element methods (BEMs) are commonly used to predict the behaviour of wave energy converters (WECs) in response to incident waves. A number ...
