Insulated overhead conductor (IOC) faults cannot be detected by the ordinary protection devices due to existence of insulation layer. The failure insulated conductors is regularly accompanied partial discharge (PD); thus, IOC are often judged PDs conductors. In this paper, an intelligent PD detection model based on bidirectional long short-term memory with attention mechanism (AM-Bi-LSTM) propo...

The energy landscape of the fast-ion conductor Bi 4 V 2 O 11 is studied using density functional theory. There are a large number minima, dominated by low-lying thermally accessible configurations in which there equal numbers oxygen vacancies each vanadium–oxygen layer, range vanadium coordinations and variation Bi–O V–O distances. By dividing local minima into sets configurations, we then exam...

Bi-2212/Ag superconducting wires are being considered as key conductor candidates for the development of high-field magnets. This work focuses on design and testing various joint structures multifilamentary Bi-2212 using powder-in-tube techniques. The joints made between unreacted subsequently heat treated with wires. microstructure transport properties different architectures including step jo...

this paper presents a new method called vespiary regular hexagonal (vrh) model to calculate parasitic capacitance between conductor wire filaments of one turn of a coil and between conductor wires filament and liner and also total capacitance of n-turns having single-layers, multi-conductor wire filaments of the helix magneto cumulative generator (mcg) coil. the presented method is an analytica...

We make a global vacuum neutrino oscillation analysis of solar neutrino data, including the seasonal and energy dependence of the recent Super–Kamiokande 708day results. The best fit parameters for νe oscillations to an active neutrino are δm = 4.42 × 10 eV, sin 2θ = 0.93. The allowed mixing angle region is consistent with bi–maximal mixing of three neutrinos. Oscillations to a sterile neutrino...

The observed L/E flatness of the electron-like event ratio in the Super-Kamiokande atmospheric neutrino data strongly favors a quasi bi-maximal mixing matrix. This situation is here exploited to understand the numerical results of Yasuda on the high energy cosmic neutrino flux. In agreement with the Yasuda result, we analytically show how the quasi bi-maximal neutrino mixing makes the high ener...

This paper describes development and initial results for a small prototype superconducting undulator with a period less than 1 cm, referred to here as a “supermini” undulator. The development of superconducting mini-undulators started in the early 1990s with work at BNL and KIT (Germany). In 1998, KIT demonstrated the first photon production with a super-mini of 3.8 mm period length [1]. This s...
