Fault Location of the Renewable Energy Sources Connected Distribution Networks Based on Time Differences of the Modal Traveling Waves

open access: yesIEEE Access, 2023
The topology of the distribution network and direction of the power flow will change when distributed generators (DGs) are connected to it, making it difficult to locate faults using conventional techniques like the impedance approach.

Some effects of galaxy structure and dynamics on the Fundamental Plane – II. A Virgo–Fornax distance modulus [PDF]

open access: yes, 1997
The influence of broken structural homology, and the implied broken dynamical homology, is examined for the Fundamental Plane (FP). Requiring a symmetrical treatment of the FP variables, a bisector method of linear regression was applied, in 3-dimensions,

(In)stability of de Sitter vacuum in light of distance conjecture and emergence proposal

open access: yesJournal of High Energy Physics, 2023
The distance conjecture claims that as the modulus traverses along the trans-Planckian geodesic distance, the effective field theory becomes invalid by a descent of a tower of states from UV.
