Tidal perturbations of the rotation of the moon: the creep tide approach
(American Astronomical SocietyParaty, 2013)
In this communication we report results from the application to the study of the rotation of the Moon of the creeping tide theory just proposed (Ferraz-Mello, Cel. Mech. Dyn. Astron., submitted. ArXiv astro-ph 1204.3957). ...

Abstract (2,250 Maximum Characters): In this communication we report results from the application to the study of the rotation of the Moon of the creeping tide theory just proposed (Ferraz-Mello, Cel. Mech. Dyn. Astron., ...
Control of rotating cylinders as suppressors of vortex-induced vibration of a bluff body
(SOBENARio de Janeiro, 2014-11-10)
The flow past a plain circular cylinder can be controlled by eight small cylinders rotating about the diameter. They rotate such that the tip speed varies from 0 to 1.5 times the free-stream velocity. A numerical approach ...

A nonlinear and non-ideal wind generator supporting structure
(2006-10-09)
We present a simple mathematical model of a wind turbine supporting tower. Here, the wind excitation is considered to be a non-ideal power source. In such a consideration, there is interaction between the energy supply and ...
A New Approach for Real Time Fault Diagnosis in Induction Motors Based on Vibration Measurement
(IEEE, 2010-01-01)
Condition monitoring is used to increase machinery availability and machinery performance, reducing consequential damage, increasing machine life, reducing spare parts inventories, and reducing breakdown maintenance. An ...
