A Study on the Transient of Secondary Arc Current of UHV Transmission Lines
IEEE Access, 2018 Secondary arcs are a type of alternating-current electric arc burning in open space, the arcing times of which are closely related to the transient of their currents.

Improved RNA pseudoknots prediction and classification using a new topological invariant [PDF]
, 2016 We propose a new topological characterization of RNA secondary structures with pseudoknots based on two topological invariants. Starting from the classic arc-representation of RNA secondary structures, we consider a model that couples both I) the ...

Analysis of The Hipparcos Measurements of HD10697 - A Mass Determination of a Brown-Dwarf Secondary [PDF]
, 2000 HD10697 is a nearby main-sequence star around which a planet candidate has recently been discovered by means of radial-velocity measurements (Vogt et al. 1999, submitted to ApJ).

Determination of Auto Reclose Scheme by Assessing Multi Parameters
IEEE AccessThis article proposes a method for determining the optimal reclose scheme in power systems. The proposed approach involves analyzing multiple parameters such as the voltage and phase angle difference between buses, critical clearing time (CCT) of the ...

IET Generation, Transmission & Distribution, 2023 Even though shunt compensation of transmission lines (TLs) is a common practice to limit the overvoltages stemming from the Ferranti effect, it may cause transient and steady‐state resonant overvoltages when one phase is left open due to the single‐pole ...

Theory of Parabolic Arcs in Interstellar Scintillation Spectra
, 2004 Our theory relates the secondary spectrum, the 2D power spectrum of the radio dynamic spectrum, to the scattered pulsar image in a thin scattering screen geometry.
