Welding is the process of coalescence two metals/alloys for creating a seamless joint, quintessential fabrication utilised in almost every manufacturing sector. There range welding processes that are used according to their features and requirement fabricator. The tungsten inert gas (TIG) an extensively owing its inherent characteristics like high weld quality, surface cleanliness, autogenous m...

 Abstract: Local flux may be distorted in many regions of core, although total flux is usually sinusoidal. When attempting to predict the loss distribution in materials operating under localized distorted flux conditions, which occur in machines and transformer cores, it is essential that proper account of the waveform be taken. Moreover for development of new magnetic materials and generation ...

this paper describes the work done between iust and two iranian steelworks to evaluate and review the performance of mould fluxes in current use for continuous casting. calculations have been performed to compare actual values of powder consumption, viscosity and break temperature of the fluxes in current use with required values derived from published empirical rules for casting conditions. it...

The flux jump instability of Bean’s critical state in the flux-creep regime of type-II superconductors is considered. We find the flux-jump field B j which determines stability criterion of the superconducting state. The dependence of B j on the external magnetic-field ramp rate Ḃe is calculated. We demonstrate that under the conditions typical for most of the magnetization experiments the slop...

on the tissue being considered. In the present case of the mossy fiber–granule cell glomerulus, spillover augments excitability by activating receptors at neighboring synapses and, therefore, increases the reliability of transmission. In addition, because adjacent granule cells presumably all sense spillover, it might help to synchronize the activity of multiple granule cells. In other tissues,...

in conventional direct torque control (dtc), the stator flux is usually kept constant by controlling the x-axis component of the stator voltage in the stator flux reference frame. the torque is then controlled by the y-axis component of stator voltage. in this scenario, the stator current does not exceed its permissible value. however, in the so-called optimal efficiency mode, the induction mot...

Magnetohydrodynamics simulation of active region NOAA 11515 is performed to examine the initiation M5.6 flaring event that starts around 10:43 UT on 2012 July 2. The conducted using an extrapolated non-force-free magnetic field generated from photospheric vector magnetogram as initial field. shows presence a three-dimensional (3D) null with corresponding dome overlying filament and low-lying fl...
