On the integrated continuum radio spectrum of supernova remnant W44 (G34.7-0.4): New insights from Planck [PDF]
Serbian Astronomical Journal, 2015 In this paper, the integrated continuum radio spectrum of supernova remnant (SNR) W44 was analyzed up to 70 GHz, testing the different emission models that can be responsible for its particular shape.

Slug Velocity Measurement and Flow Regime Recognition Using Acoustic Emission Technology [PDF]
, 2013 Slug velocity measurement and flow regime recognition using acoustic emission technology are presented. Two non-intrusive and three intrusive methods were employed to detect the slug regime and measure its velocity using AE sensors. For the non-intrusive

Известия высших учебных заведений: Проблемы энергетикиUnplanned overhead power line outages are typically associated with flashover of line insulation due to contamination and moisture. Powerful partial discharges on the insulation surface (SPD) can serve as a precursor to flashover. They can be detected by

Tailoring emission spectra by using microcavities
Results in Physics, 2019 We present a theoretical model to describe emission spectrum of an emitter in a micro-cavity. Our model proposes that the spectrum in a metal micro-cavity depends on the product of the emission spectrum in free space and the local density of states (LDOS)

Quasiclassical approach to synergic synchrotron–Cherenkov radiation in polarized vacuum
New Journal of Physics, 2020 Photon emission by an ultrarelativistic charged particle in extremely strong magnetic field is analyzed, with vacuum polarization and photon recoil taken into account. Vacuum polarization is treated phenomenologically via refractive index.
