Abstract In frequency analysis an often appearing problem is the reconstruction of a signal from given samples. Since samples are usually noised, pure interpolating approaches not recommended and appropriate approximation methods more suitable as they can be interpreted kind denoising. Two widely used. One uses reflection coefficients finite sequence Szegő polynomials other one zeros so called ...

Highly accurate potential energy functions for the HeI and HeBr molecules have been calculated using an ab initio treatment that included basis set extrapolation to the complete basis set, as well as spin-orbit coupling in the ground 2sigma+ and first 2pi excited doublet states. The rovibronic bound state energies and resonance lifetimes were also evaluated by a Prony analysis of the autocorrel...

Preliminary notes Dynamic disturbances in the electric power system exert influence on the operation of generators and cause several other disturbances, such as a power swing, resulting in the activation of protections, the stalling of generators and their disconnection from the grid. The application of synchronized measurements in the field of power swing has mainly been focused on a transmiss...
