Developing Digital Control System Centrifugal Pumping Unit Digital Control Systems

Currently, the leading Russian oil companies engaged in the development of automatic control systems (ACS) oil equipment, to improve its efficiency. As an example of an object needed to optimize its work, a centrifugal pumping unit (CPU) can be specified. Frequency actuators provide an opportunity to run CPU in any algorithm, and many industrial controllers, are part of the automatic control sy...

Counter-rotating bars within bars

The dynamical stability and evolution of disc galaxies with different disc thickness as well as various fraction and concentration of stellar counter-rotation is investigated with self-consistent numerical simulations. In particular, systems of nested, counter-rotating, stable bars are presented. As for the direct case, the nuclear secondary bar rotates faster than the primary bar. Contrary to ...

Counter Rotating Currents Cryogenic Surface Coils

Introduction. Noise in MRI systems, in general, is created by conductive losses in the coil and in the body. When the coil loss is the governing source of noise (Rcoil>Rbody), it has long been recognized that cooling the coil reduces this noise contribution and therefore can significantly increase the SNR [1]. Such an SNR increase has been demonstrated by many groups with two-fold and higher SN...

Rapid AGN accretion from counter–rotating discs

Accretion in the nuclei of active galaxies may occur chaotically. This can produce accretion discs which are counter–rotating or strongly misaligned with respect to the spin of the central supermassive black hole (SMBH), or the axis of a close SMBH binary. Accordingly we consider the cancellation of angular momentum in accretion discs with a significant change of plane (tilt) between inner and ...
