In this paper, generalizations of the Stokes parameters and alternative characterizations of three-dimensional (3D) time-varying electromagnetic fields is introduced. One of these characteristics is the normal of the polarization plane, which, in many cases of interest, is parallel (or antiparallel) to the direction of propagation. Others are the two spectral density Stokes parameters which des...

The spectral parameters (energy levels, wavelengths, transition probabilities, line strengths and oscillator strengths) of resonance lines for Ba VIII, La IX Ce X have been performed using the multiconfiguration Dirac-Hartree-Fock method, contributions quantum electrodynamics Breit interactions correction are taken into considered. calculated results energy levels wavelengths in good agreement ...

Landmarks in speech signal are regions with abrupt spectral variations. Automated detection of these regions is important for several applications in speech processing. Performance of landmark detection using parameters extracted from predefined spectral bands generally gets limited by speaker related spectral variability. This paper presents a landmark detection technique which adapts to the a...
