Characteristics of Low-Latitude Coronal Holes near the Maximum of Solar cycle 24 [PDF]

, 2017
We investigate the statistics of 288 low-latitude coronal holes extracted from SDO/AIA-193 filtergrams over the time range 2011/01/01 to 2013/12/31. We analyse the distribution of characteristic coronal hole properties, such as the areas, mean AIA-193 ...

Experimental Study of Heat Flux Distribution of Arc Driven by AC Magnetic Field

Advances in Materials Science and Engineering, 2011
The authors earlier developed a model to predict the heat flux distribution in an arc driven by an AC magnetic field. That theoretical model implied that the heat flux distribution depended on waveforms of the imposed AC magnetic field.

Magnetic Fluxes

, 2023
AbstractWe have already seen that the spectra of quantum graphs are independent of the particular form of the magnetic potential (5.8)—only integrals of the magnetic potential along the edges play a role. One may say that adding magnetic potential is equivalent to a special change of vertex conditions.

Design and optimization of a mechanical variable-leakage-flux interior permanent magnet machine with auxiliary rotatable magnetic poles

CES Transactions on Electrical Machines and Systems, 2021
A novel mechanical variable-leakage-flux interior permanent magnet machine (MVLF-IPMM) is proposed for electric vehicles (EVs) in this paper, which employs a mechanical flux-regulating device and auxiliary rotatable magnetic poles.
