Static and Dynamic Voltage Balancing for an IGCT-Based Resonant DC Transformer
Drazen Dujic, Renan Pillon Barcelos, Nikolina Djekanovic
This paper focuses on the operational characteristics of a medium voltage resonant DC transformer based on a split capacitor IGCT 3L-NPC leg. The study delves into both the dynamic and static balancing aspects of the 3L-NPC when operating in a two-level, 5 ...
2024Orbital-Resolved DFT plus U for Molecules and Solids
Nicola Marzari, Iurii Timrov, Eric Macke
We present an orbital-resolved extension of the Hubbard U correction to density-functional theory (DFT). Compared to the conventional shell-averaged approach, the prediction of energetic, electronic and structural properties is strongly improved, particula ...
Amer Chemical Soc2024Power performance of a model floating wind turbine subjected to cyclic pitch motion: A wind tunnel study
Fernando Porté Agel, Guiyue Duan, Daniele Gattari
Offshore floating wind turbines (OFWTs) are becoming increasingly popular due to their ability to exploit deep-sea wind resources. However, since wind turbines are installed on floaters instead of solid foundations, the dynamic response of an OFWT due to ...
2024Modelling of energetic particle drive and damping effects on TAEs in AUG experiment with ECCD
Alexander Karpushov, Giovanni Tardini
The impact of electron cyclotron current drive (ECCD)-driven current on toroidicity-induced Alfven eigenmodes (TAEs) in experiments on the AUG tokamak is investigated numerically. The dynamical evolution of the plasma profiles and equilibria are modelled w ...
Bristol2024Strain-based analysis on the influence of local undercut geometry on fatigue crack initiation life
Alain Nussbaumer, Heikki Tapani Remes, Abinab Niraula
The local undercut defects at the weld toe provide a potential initiation site for fatigue cracks and significantly impact the structure's fatigue strength. The influence of continuous undercut depth on fatigue performance is widely studied, but the resear ...
2024Gene expression of Pocillopora damicornis coral larvae in response to acidification and ocean warming
Objectives The endosymbiosis with Symbiodiniaceae is key to the ecological success of reef-building corals. However, climate change is threatening to destabilize this symbiosis on a global scale. Most studies looking into the response of corals to heat str ...
London2024Fast refacing of MR images with a generative neural network lowers re-identification risk and preserves volumetric consistency
Jean-Philippe Thiran, Tobias Kober, Bénédicte Marie Maréchal, Jonas Richiardi
With the rise of open data, identifiability of individuals based on 3D renderings obtained from routine structural magnetic resonance imaging (MRI) scans of the head has become a growing privacy concern. To protect subject privacy, several algorithms have ...
Wiley2024Method for wind harvesting and wind rejection in flying drones
Dario Floreano, Charalampos Vourtsis, Victor Casas Rochel, Nathan Samuel Müller, William John Stewart
The present invention concerns a method of manoeuvring a vertical take-off and landing, unmanned aerial drone (100) comprising at least an aerodynamic surface (101), wherein, during a flight of the drone, the aerodynamic surface generates lift and/or drag ...
2024A moored profiling platform to study turbulent mixing in density currents in a large lake
David Andrew Barry, Ulrich Lemmin, François Mettra, Rafael Sebastian Reiss, Valentin Kindschi, Benjamin Daniel Graf
During calm cooling periods, differential cooling can induce winter cascading which is an important process for littoral-pelagic exchange and deep water renewal in large, deep lakes (Fer et al., 2001; Peeters et al., 2003). Generated in the shallow near-sh ...
2023Synthesis Report on the Environmental Impacts of Polar Research and Logistics in the Polar Regions
Polar sciences are crucial to understand the effects of climate change. 6 out of 9 eco-tipping points identified by the IPCC are situated in the polar regions. Potential rising sea levels, altered weather patterns and changes in sea-currents are all connec ...
