Noise Reduction in a Reputation Index [PDF]
Assuming that a time series incorporates “signal” and “noise” components, we propose a method to estimate the extent of the “noise” component by considering the smoothing properties of the state-space of the time series. A mild degree of smoothing in the

Adaptive Noise Reduction System [PDF]
Noise is an all-present environment pollutant, considered to be one of the greatest contemporary pollutants. World-wide, co-ordinated actions are conducted in order to develop systems which minimise the noise influence onto society.In this article we ...

Hole making characteristics of novel domestic T800 carbon fiber reinforced composite
In view of the defects of the new domestic T800 carbon fiber reinforced plastic (CFRP), such as lamellar tearing and fiber loss, which would be easily caused by large drilling force and torque during cutting, an experimental platform including a vertical

Torsional vibration analysis of shaft with multi inertias
An analytical method is proposed to investigate the torsional vibration of the uniform circular shaft with multiple concentrated inertias. The governing equation is established based on the Hamiltonian principle and verified by the dynamical method.
