Transformer Resonance: Reasons, Modeling Approaches, Solutions
IEEE Access, 2023 Due to the extension of the power grid with many complex and compact pieces of power equipment, transformers will be more exposed to fast transient, resulting from various resonance conditions.

A Survey for Fast Transients in the Fornax Cluster of Galaxies [PDF]
The Astrophysical Journal, 2008 The luminosity gap between novae (M_R < -10) and supernovae (M_R > -14) is well known since the pioneering research of Zwicky and Hubble. Nearby galaxy clusters and concentrations offer an excellent opportunity to search for explosions brighter than classical novae and fainter than supernovae. Here, we present the results of a B-band survey of 23

On the nature of fast blue optical transients
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT Short rise times of fast blue optical transients (FBOTs) require very light ejected envelopes, $M_{\rm ej} \le 10^{-1} \, \mathrm{M}_\odot$, much smaller than of a typical supernova. The detection by Chandra of X-ray emission in AT2020mrf of LX ∼ 1042 erg s−1 after 328 d implies total, overall dominant, X-ray energetics at the ...

Fast evaluation of transient acoustic fields [PDF]
The Journal of the Acoustical Society of America, 2016 The efficient computation of transient fields radiated by non-harmonic source distributions is a problem relevant in numerous areas of acoustics. This paper presents an efficient easily implemented method for the generation of time-dependent spherical harmonic expansions for arbitrary sources, which can be used to compute the transient radiated field ...
