A reduced-order, rotation-based model for thin hard-magnetic plates
Pedro Miguel Nunes Pereira de Almeida Reis, Dong Yan, Bastien Freddy Gustave Aymon
We develop a reduced-order model for thin plates made of hard magnetorheological elastomers (hard-MREs), which are composed of hard-magnetic particles embedded in a polymeric matrix. First, we propose a new magnetic potential, as an alternative to an exist ...
PERGAMON-ELSEVIER SCIENCE LTD2023Automated test setup to quantify the lifetime of dielectric elastomer actuators under a wide range of operating conditions
Herbert Shea, Fabio Beco Albuquerque, Djen Timo Kühnel, Valentin Colin Py
We present an automated test setup for the systematic performance and lifetime evaluation of dielectric elastomer actuators (DEAs). This setup, called the MAPLE setup, performs accelerated aging tests and allows quantifying how material choice, fabrication ...
IOP PUBLISHING LTD2021A formula for the admittance of laterally excited bulk wave resonators (XBARs)
Luis Guillermo Villanueva Torrijo, Soumya Yandrapalli, Victor Plessky
The recently invented laterally excited bulk wave resonators (XBARs) demonstrate outstanding parameters suitable for the design of low loss filters for the fifth generation of mobile phones. The operation of XBARs can be interpreted as an excitation of ant ...
WILEY2021The Polarity Reversal of Lightning‐Generated Sky Wave
Marcos Rubinstein, Mohammad Azadifar, Wenhao Hou
The polarity reversal of the lightning‐generated first sky wave as a function of the observation distance is studied using a novel approach combining the finite‐difference time domain (FDTD) method and the superposition principle of electromagnetic waves. ...
2020Two Possible Scenarios for the Formation of Category 1 Bipolar Lightning Flashes
Marcos Rubinstein, Mohammad Azadifar, Davide Pavanello, Qi Li
We present and discuss the current and electric field waveforms associated with two upward bipolar lightning flashes that occurred at the Säntis Tower. According to the traditional classification of bipolar flashes, both observed flashes could be classifie ...
2019Magnetic Stability of Single Lanthanide Atoms on Graphene
This thesis presents a study of the magnetism of surface supported atoms performed principally with XMCD spectroscopy and multiplet calculations.
The objective of the research was twofold: first, to study the underlying interactions and conditions governi ...
EPFL2018Spin dynamics of coupled spin ladders near quantum criticality in Ba2CuTeO6
We report inelastic neutron scattering measurements of the magnetic excitations in Ba2CuTeO6, proposed by ab initio calculations to magnetically realize weakly coupled antiferromagnetic two-leg spin-1/2 ladders. Isolated ladders are expected to have a sing ...
2018Cold pulse and rotation reversals with turbulence spreading and residual stress
Transport modeling based on inclusion of turbulence spreading and residual stresses shows internal rotation reversals and polarity reversal of cold pulses, with a clear indication of nonlocal transport effects due to fast spreading in the turbulence intens ...
American Institute of Physics2016The sediment-contact test using the ostracod Heterocypris incongruens: Effect of fine sediments and determination of toxicity thresholds
The toxicity test using freshwater ostracods of the species Heterocypris incongruens is a sub-chronic static test that exposes individuals to whole sediments over a period of 6 d, the endpoints being mortality and growth. We tested the hypothesis that endp ...
Pergamon-Elsevier Science Ltd2016Cyclic Hypervalent Iodine Reagents and Pd-Catalysis
Developing new strategies and methods to explore new dimensions of the chemical space represents an important goal for organic chemists. One particular synthetic approach that emerged in the last decades is Umpolung: the normal polarity of chemical functio ...
