Artificial Neural Networks (ANNs) are being applied as a faster alternative to Computational Fluid Dynamics (CFD) for wind turbine engineering wake models. Unfortunately, ANNs can fail to generalize if the data is insufficient. Physics-Informed Neural Networks (PINNs) can improve convergence while lowering the required data amounts. This paper inve...

Real-time phase mapping (ExTRa™) is useful in determining the strategy of catheter ablation for non-paroxysmal atrial fibrillation (AF). This study aimed to investigate the features of drivers of AF associated with its termination during ablation. Thirty-six patients who underwent catheter ablation for non-paroxysmal AF using online real-time phase...
This study presents a sizing methodology in the frame of the multidisciplinary design of interior permanent magnet synchronous machines. The proposed approach targets at obtaining an initial electromagnetic design of the machine, including diameters, axial length, rotor barrier shape, stator slot geometry as well as the winding layout. The analytic...
This work presents an actuator disk-like body force method designed for propeller modeling, which is based on a full coupling between computational fluid dynamics (CFD) and blade element theory (BET). An analysis is conducted on the model to identify best practices for source term distribution. It is found that the source term volume shape has no i...
This paper presents the activities performed in the GARTEUR Action Group HC/AG-26 to study the acoustic and aerodynamic characteristics of small rotor configurations, including the influence of the rotor-rotor interactions. This paper will focus on comparisons between numerical activities and wind tunnel results on a small rotor provided by DLR. Th...
The rising interest in urban air mobility has brought new challenges in terms of noise pollution. Developing dedicated methods to accurately predict the noise generated by such aircraft configurations is thus a cornerstone to be able to meet the noise emission requirements in an urban environment. This work presents three numerical approaches, with...

Treatment of atrial fibrillation (AF) remains challenging despite significant progress in understanding its underlying mechanisms. The first detailed, quantitative theory of functional re-entry, the 'leading circle' model, was developed more than 40 years ago. Subsequently, in decades of study, an alternative paradigm based on spiral waves has long...
REDO-FIRM evaluated safety and effectiveness of conventional vs. focal impulse and rotor modulation (FIRM)-guided ablation of recurrent persistent or paroxysmal atrial fibrillation (AF) after an initial AF ablation procedure. This prospective, multicentre, randomized study included patients with a single prior AF ablation, but with recurrent AF and...
Multi-three-phase motor drives are experiencing a significant development among the multiphase solutions since they are configured as multiple three-phase units operating in parallel. Although the literature reports several torque controllers able to deal with multi-three-phase motors, most of them obtain high performance of torque regulation as lo...
