This article is devoted to the adaptive asymptotic tracking for a class of uncertain nonlinear systems. The presence of unknown time-varying parameters and uncertain disturbances makes the systems in question essentially different from those in the ...

Circuits Systems and Signal Processing, 1996
We examine a generalized matched-filter problem in which the interference is a nonstationary process generated by passing white noise through a general linear time-varying filter. First a matched filter is constructed by transforming the problem into an equivalent formulation involving stationary interference and a time-varying propagation channel ...

Numerical Methods for Partial Differential Equations, 2018
Artificial compression methods create nonphysical acoustic waves. Time filters, often used in geophysical fluid dynamics, are shown in this paper to selectively damp these acoustics.

The time filter for the non-stationary coupled Stokes/Darcy model
, 2019In this paper, we consider the effect of adding a simple time filter to the Backward Euler scheme for the non-stationary coupled Stokes/Darcy model.

Rolling bearings are the key components of rotating machinery. Thus, the prediction of remaining useful life (RUL) is vital in condition-based maintenance (CBM). This paper proposes a new method for RUL prediction of bearings based on time-varying Kalman

A filter is a two port that shapes the spectrum of the input signal in order to obtain an output signal with the desired frequency content. Thus, a filter has passbands where the frequency components are transmitted to the output and stop bands where they are rejected.

A method is described for measuring low-level time-truncated signals by using narrow-bandwidth synchronous time-notch filters. These filter systems, intended for use with ordinary narrowband receivers or field intensity meters, provide a means of isolating time-truncated signals of interest from adjacent interfering signals.

Temporal filtering with time lenses
Applied Optics, 1992We propose to use optics for ultrafast serial processing by employing the well known analogy between optical spatial diffraction and temporal dispersion. The essence of this analogy can be stated briefly like this: The temporal frequency corresponds to the spatial frequency in the lateral direction, and the time t corresponds to the lateral coordinate ...
