In this paper, a Switched Reluctance Motor (SRM) drive system is proposed to make trade-off between torque profile and vibration amplitude. the system, power factor correction fast demagnetization are achieved using single-phase Vienna rectifier as front-end converter for SRMs with nominal voltage equal half DC-link voltage. The three-level provides doubled negative in demagnetization, resultin...

Redshift obeys adiabatic invariance. From this fact it follows that not only the individual photons are dimmed by a factor of z + 1 (if z is the redshift in percent), but the photon flux is reduced by the same factor once more. Hence the luminosity of any source is in the presence of redshift dimmed by a factor of (z+1). This model-independent result possibly "explains away" the excess dimming ...

A major challenge facing adiabatic quantum computing is that algorithm design and error correction can be difficult for adiabatic quantum computing. Recent work has considered addressing this challenge by using coherently controlled adiabatic evolutions in the place of classically controlled evolution. An important question remains: what is the relative power of controlled adiabatic evolution t...

Hysteresis loops of Nd-Fe-B magnets with different surface roughness are measured in order to investigate the surface effect on nucleation for magnetization reversal. The roughness affects both coercivity and the demagnetization process. This behavior is considered to be caused by the 90° domain wall pinning of the line scratches.

70% of the patients affected by PSP are not correctly diagnosed in the first 2 to 3 years of the disease. I personally have followed three patients who at CT presented the features of PSP while none of them showed clinical signs definitively suggestive of the disease. This suggests that the CT findings could be present before the complete clinical manifestation of the syndrome, at least in a nu...

Note describes two experiments made to explore basic properties of permanent magnet (PM) material and to obtain “first hand” experience. In the first experiment, magnetic moments of NdFeB permanent magnets (PM) were fine tuned. The magnetic moment spread among 17 PM magnets was reduced by a factor of 5 from 2.8% to 0.5%. The note describes setup used for magnetization and presents result. The s...
