The nonlinear evolution of unstable C-type shocks in weakly ionized plasmas is studied by means of time-dependent magnetohydrodynamical simulations. This study is limited to shocks in magnetically dominated plasmas (in which the Alfvén speed in the neutrals greatly exceeds the sound speed), and microphysical processes such as ionization and recombination are not followed. Both two-dimensional s...

The paper outlines a method for inclusion of the impact of eddy-currents in the model for dynamic prediction of current waveform and force of a switched reluctance machine. The method is based on the equivalent electric circuit model which accounts for the impacts of magnetic saturation and eddy currents in the magnetic core. A linear tubular switched reluctance machine, which includes solid st...

Nowadays study of input voltage quality on induction motors behavior has become a controversial subject due to the wide application of these motors in the industry. The impact of grid voltage fluctuations on the performance of induction motors can be included in this area. The majority of papers devoted to the influence of voltage fluctuations on the induction motors are focusing only on the so...

We present magnetic flux measurements in seven rapidly rotating M dwarfs. Our sample stars have X-ray and H-alpha emission indicative of saturated emission, i.e., emission at a high level independent of rotation rate. Our measurements are made using near-infrared FeH molecular spectra observed with HIRES at Keck. Because of their large convective overturn times, the rotation velocity of M stars...

Magnetic field effects (MFEs) due to the∆g mechanism on the hydrogen abstraction reaction of 4-methoxybenzophenone with thiophenol in 2-methyl-1-propanol were studied at 293K by a laser flash photolysis technique under ultrahigh magnetic fields of up to 28T. The yield of the escape ketyl radical decreased with increasing magnetic field from 0 to 10T. The decrease, however, was almost saturated ...

The saturation of the magnetic resonance of paramagnetic impurities in metallic hosts is investigated. The earlier work of N. Bloembergen is extended to metallic films of finite thickness. The absorption line shape and its derivative with respect to the static applied field are calculated. Comparison is made with the corresponding results for an insulating host, and suggestions are given as to ...

The paper presents the tridimensional analysis of electromagnetic field of an claw poles alternator, in whose construction has been used non-magnetic material, such aluminum, that form the rings in the rotor’s structure. This structure aims to establish lower levels of saturation in the claw-pole of Lundell alternator. Reducing the level of saturation in the rotor, lead to reduction of the loss...

We have determined the physical mechanism responsible for the plasma instabilities, which was first found by Ramani and Laval (1978), associated with anisotropic velocity distributions induced by the temperature gradient in which there are growing low frequency transverse magnetic waves, even in the absence of background magnetic fields. We have shown that the physical mechanism responsible for...
