Noise of counter-rotation propellers
9th Aeroacoustics Conference, 1984Theory is presented for noise generation of counter-rotat ion (CR) propellers with special emphasis given to the effects of acoustic and aerodynamic interference between the two rotors. New radiation formulas are given for noise caused by unsteady loading.

Visualisation of counter-rotating ring currents in kekulene
Chemical Communications, 2001Current-density maps for kekulene 1 computed using an ab initio all-electron distributed-origin method show global diamagnetic and paramagnetic circulations around outer and inner perimeters (‘rim’ and ‘hub’), subsuming six local benzenoid diamagnetic π circulations, in qualitative agreement with the Huckel–London π model, but in ...

Aircraft Engineering and Aerospace Technology, 1972
A ROTATING PLASTIC DISC, such as a Frisbee, indicates high lift coefficients. To examine this phenomenon, experimental research was conducted, using a specially‐constructed rotating water tank. Test results demonstrated both lift increase and drag decrease for rotating discs compared to values for nonrotating discs.

The counter-rotating terms in the superradiance
Il Nuovo Cimento D, 1986It is pointed out that the counter-rotating terms play an important role in the superradiance of the first kind, in which the atomic system is initially in an uncorrelated state with maximal dipole moment. If the counter-rotating terms are added to the master equation for the Dicke model derived by Agarwal and Bonifacioet al., the numerical solutions ...

Load balancing in counter-rotated SONET rings
Proceedings of the 1999 International Conference on Parallel Processing, 2003Load-balanced routing in SONET rings has attracted much attention recently. Most prior works model the SONET rings as undirected rings and the traffic as undirected chords. While this model fits well to the traditional telephony applications, it is inefficient for the explosive Internet traffic and multimedia data communications, which exhibit ...

Kantowski Sachs universes with counter-rotating dust
Classical and Quantum Gravity, 2002In 1939, Einstein solved the field equations of general relativity to describe a cluster of particles moving in circular orbits about the center of the system. These Einstein clusters have been studied extensively. In a series of recent papers (see Zbl 0999.83072, Zbl 1001.83032, and Zbl 1005.83043), the author presented a solution of Einstein's ...
