This paper presents an efficient method of quasi-periodic noise detection and filtering. Taking into account that periodic noise leaves peaks in the amplitude spectrum, the proposed approach focuses on their detection and elimination. The detection is performed semiautomatically using a local median whereupon the localized peaks are eliminated by a modified Gaussian notch filter. The proposed a...

Instrument function is a measure of the intensity distribution in the output plane of a spectroscopic system assuming the input to be an ideal sharp isolated spectral line [1]. It is very essential to know, apart from the resolution limit of the spectrometer also the complete instrument function for the measurement of the exact line profile of spectral sources. The resolution properties of a sp...

The nucleon spectral function in infinite nuclear matter is calculated in a quantum transport theoretical approach. Exploiting the known relation between collision rates and correlation functions the spectral function is derived self-consistently. By re-inserting the spectral functions into the collision integrals the description of hard processes from the high-momentum components of wave funct...

The effective complex conductivity σeff of a two-component material can be conveniently expressed as an integral transformation of a spectral function. The spectral function depends only on the geometry of the material, and can be used to calculate σeff for any particular choice of component conductivities. This is a very useful feature if the component conductivities can be varied (by changing...
