A method based on the concepts of stochastic averaging and equivalent linearization is presented for determining the response of a lightly damped nonlinear single-degree-of-freedom oscillator to a ...

Researchers at the University of Tsukuba employ a modified mathematical technique to make complicated nonlinear equations more tractable, which can lead to more accurate control systems for mechanical ...

The problem of nonlinear filtering is studied asymptotically as the noise tends to zero. Detectability conditions ensuring that the filtering error tends to zero are ...

In aircraft and aerospace structures, nonlinear structural phenomena can be observed under certain loading and boundary conditions. Traditional structural and aeroelastic analyses techniques have been ...

It appears that no particular approximate [nonlinear] filter is consistently better than any other, though . . . any nonlinear filter is better than a strictly linear one. 1 The Kalman filter is a ...
