Transients in the load node at power loss: group run-out of induction motors [PDF]

E3S Web of Conferences, 2019
The simulation of transient processes in the complex load node with powerful induction motors at the moment of power loss is carried out. For the modeling the method of synthetic schemes (Dommel’s algorithm) was used.

A Software for RFI Analysis of Radio Environment around Radio Telescope

Universe, 2023
Radio astronomy uses radio telescopes to detect very faint emissions from celestial objects. However, human-made radio frequency interference (RFI) is currently a common problem faced by most terrestrial radio telescopes, and it is getting worse with the

The Murchison Widefield Array [PDF]

, 2010
It is shown that the excellent Murchison Radio-astronomy Observatory site allows the Murchison Widefield Array to employ a simple RFI blanking scheme and still calibrate visibilities and form images in the FM radio band.
