Almost periodic functions are a fascinating area of study in mathematics, particularly in the context of differential equations. These functions exhibit a form of regularity that is not strictly ...

GACS processes have multivariate statistical functions that are almost-periodic function of time. The (generalized) Fourier series of these functions have both coefficients and frequencies, named ...

Abstract: The filter response of nonuniform, almost-periodic structures, such as corrugated optical waveguides ... For small reflectivities, the filter response is a Fourier transform of the taper ...
