Development of a continuous broad-energy-spectrum electron source [PDF]
, 1985 The development of a practical prototype, large-area, continuous-spectrum, multienergy electron source to simulate the lower energy (approx = 1 to 30 keV) portion of the geosynchronous orbit electron environment was investigated.

Robust Identification Method for Transmission Line Parameters That Considers PMU Phase Angle Error
IEEE Access, 2020 Accurate transmission line parameters are the basis of power system calculations. The measured phasor measurement unit (PMU) phase angle data at both ends of a line may contain large errors caused by synchronization problems, which can seriously affect ...

Leptonic origin of the 100 MeV gamma-ray emission from the Galactic Centre
, 2015 The Galactic centre is a bright gamma-ray source with the GeV-TeV band spectrum composed of two distinct components in the 1-10 GeV and 1-10 TeV energy ranges. The nature of these two components is not clearly understood.

Fermionic Tachyons as a Source of Dark Energy
, 2019 A model for the universe on the basis of a self interacting fermionic tachyon field is investigated here. It is shown that, devising a self interaction potential of a proper form, the fermionic tachyon field is capable of producing an accelerating ...
