An optimal preconditioned FFT-accelerated finite element solver for homogenization
Till Junge, Ali Falsafi, Martin Ladecký
We generalize and provide a linear algebra-based perspective on a finite element (FE) ho-mogenization scheme, pioneered by Schneider et al. (2017)[1] and Leuschner and Fritzen (2018)[2]. The efficiency of the scheme is based on a preconditioned, well-scale ...
ELSEVIER SCIENCE INC2023Quantification of successful encapsulation into microfluidic compartments
The invention provides a method for quantifying the number of target entities that were successfully encapsulated into a microfluidic compartment such as a microfluidic droplet. The invention is predicated upon a continuous quantifiable detectable signal c ...
2022Laser photo-detachment combined with Langmuir probe in magnetized electronegative plasma: how the probe size affects the plasma dynamic?
Laser photo-detachment combined with a Langmuir probe (LP) is used to diagnose negative ion properties in electronegative plasmas. The technique relies on the combined use of a laser pulse and an LP. The laser pulse converts negative ions into electron-ato ...
IOP Publishing Ltd2021Dynamic Modeling and Control of a Coupled Reforming/Combustor System for the Production of H2 via Hydrocarbon-Based Fuels
The present work aims to provide insights into the dynamic operation of a coupled reformer/combustion unit that can utilize a variety of saturated hydrocarbons (HCs) with 1–4 C atoms towards H2 production (along with CO2). Within this concept, a preselecte ...
2020Controlling oscillations in high-order Discontinuous Galerkin schemes using artificial viscosity tuned by neural networks
Jan Sickmann Hesthaven, Niccolo' Discacciati, Deep Ray
High-order numerical solvers for conservation laws suffer from Gibbs phenomenon close to discontinuities, leading to spurious oscillations and a detrimental effect on the solution accuracy. A possible strategy to reduce it comprises adding a suitable amoun ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2020Sampling and Reconstruction of Bandlimited Signals with Multi-Channel Time Encoding
Martin Vetterli, Adam James Scholefield, Karen Adam
Sampling is classically performed by recording the amplitude of the input at given time instants; however, sampling and reconstructing a signal using multiple devices in parallel becomes a more difficult problem to solve when the devices have an unknown sh ...
2020Proton-transfer-induced 3D/2D hybrid perovskites suppress ion migration and reduce luminance overshoot
Mohammad Khaja Nazeeruddin, Emad Oveisi, Hobeom Kim
Perovskite light-emitting diodes (PeLEDs) based on three-dimensional (3D) polycrystalline perovskites suffer from ion migration, which causes overshoot of luminance over time during operation and reduces its operational lifetime. Here, we demonstrate 3D/2D ...
2020Metabolic and hemodynamic changes in the activated human brain and cerebellar organisation measured by MRS/MRl at 7 Tesla
Although less often investigated than the positive blood-oxygen-level-dependent (BOLD) signal, a negative BOLD signal has also been observed under certain conditions, which could have a neuronal origin. To further investigate the negative BOLD signal from ...
EPFL2020Nonlinear piezoelectric vibration energy harvester with frequency-tuned impacting resonators for improving broadband performance at low frequencies
Nico de Rooij, Danick Briand, Andres Felipe Vasquez Quintero, Robert Andrew Lockhart
The paper reports on a nonlinear frequency up-converting vibration energy harvester with enhanced broadband performance below 50 Hz, which is attained by leveraging vibro-impact interaction between two high-frequency piezoelectric generators and two low-fr ...
