Numerical Modeling of Multiphase, Turbulent Galactic Disks with Star Formation Feedback

, 2012
Star formation is self-regulated by its feedback that drives turbulence and heats the gas. In equilibrium, the star formation rate (SFR) should be directly related to the total (thermal plus turbulent) midplane pressure and hence the total weight of the ...

Symmetrical/Asymmetrical Winding Reconfiguration in Multiphase Machines

IEEE Access, 2020
This paper investigates multiphase drives in which winding configuration (symmetrical or asymmetrical) can be easily obtained by only rearranging voltage source inverter (VSI) power supply cables at the machine's terminal box.

Doppler radar with multiphase modulation of transmitted and reflected signal [PDF]

, 1989
A microwave radar signal is generated and split by a circulator. A phase shifter introduces a series of phase shifts into a first part of the split signal which is then transmitted by antenna.
