Longitudinal Loads From Broken Conductors and Broken Insulators and Their Effect on Transmission Lines

IEEE Transactions on Power Apparatus and Systems, 1980
A review of a study of the longitudinal loads on a suspension tower and the dynamic response of aans- transmission line following a broken conductor or dropped insulator is presented. Included are the results of full-scale tests conducted on an existing electric transmission line.

Steady longitudinal motion of an insulating cylinder in a conducting fluid

Mathematical Proceedings of the Cambridge Philosophical Society, 1968
AbstractA mathematical analogue between a special class of problems in steady magnetohydrodynamics and appropriate problems in the theory of the scattering of sound pulses is established and exploited. Rigorous asymptotic expansions for large Hartmann numberMare obtained for the exact solution of the prototype problem, the circular cylinder. Asymptotic

The insulated cylindrical antenna in a cold plasma with a longitudinal magnetic field

IEEE Transactions on Antennas and Propagation, 1968
The tangential electric field excited on the conducting surface of a transmitting antenna is calculated by modifying a variational impedance formulation. For an antenna in a magnetoionic medium, the boundary condition requiring that the tangential electric field vanish on the surface is satisfied to approximately the same degree as for dielectric ...

Investigation of the magnetic properties of insulating thin films using the longitudinal spin Seebeck effect

Journal of Applied Physics, 2014
The longitudinal spin Seebeck effect is used as a detector for the magnetic properties and switching characteristics of magnetic thin insulating films. We use a 300 nm and a 20 nm thick Yttrium Iron Garnet (YIG, Y3Fe5O12) film prepared by pulsed laser deposition and afterwards coated by platinum for the detection of the thermally excited magnons by the

Longitudinal susceptibility and the question of zero magnons in low-temperature magnetic insulators

Physical Review B, 1974
The longitudinal susceptibility of the low-temperature Heisenberg ferromagnet is treated in random-phase approximation (RPA) in order to discuss whether a zero magnon (spin-density mode in the collisionless regime) can exist. In the unrenormalized RPA, this mode is found at large wave vectors in systems which have an exchange anisotropy which enhances ...

Two-dimensional semimetal-insulator transition in HgTe-based quantum wells induced by a longitudinal magnetic field

JETP Letters, 2012
A metal-insulator transition in a two-dimensional semimetal based on HgTe quantum wells is discovered. The transition is induced by a magnetic field applied parallel to the plane of the quantum well. The threshold behavior of the activation energy as a function of the magnetic-field strength and an abrupt reduction of the Hall resistance at the onset ...

Stable Single-Longitudinal-Mode Fiber Ring Laser Using Topological Insulator-Based Saturable Absorber

Journal of Lightwave Technology, 2014
A single-longitudinal-mode (SLM) fiber ring laser based on topological insulator (TI) Bi2Te3 saturable absorber (SA) had been experimentally demonstrated. The TI: Bi2Te3 nanosheets, which were fabricated through the bottom-up approach, were coated onto the microfiber as an efficient saturable absorber device to ensure the SLM operation.

Flash-over voltage prediction of silicone rubber insulators under longitudinal and fan-shaped non-uniform pollution conditions

Computers & Electrical Engineering, 2019
Abstract This paper proposes an Artificial Neural Network (ANN) model for AC flash-over voltage prediction of Silicone Rubber (SiR) insulators based on the experimental tests. In flash-over tests, the flash-over voltages of four different types of SiR insulators are measured under the uniform, longitudinal non-uniform, fan-shaped non-uniform and ...

[Longitudinal study of radiologic anomalies in subjects working in asbestos-insulated buildings].

Revue d'epidemiologie et de sante publique, 1996
The respiratory effects of environmental pollution by asbestos was examined in a cohort of subjects working inside university buildings partly insulated with asbestos containing materials (University of Jussieu in Paris). The present study concerned 727 subjects having undergone two standard radiographic examinations (postero-anterior and oblique chest
