... Progress in the development of the 1996 release of the IDL Wavelet Workbench (WWB) is shown. The WWB is now improved in several ways, among them are: (1) a smarter GUI which easily directs the user to the possibilities of the WWB, (2) the inclusion of more wavelets, (3) the enhancement of the input and output modules to provide a better interface to the input and output data and (4) the addition of more analysis methods based on the wavelet transform. ... More analysis routines are now available. ...

... Several attempts to discover the FICN signal in VLBI nutation series made during last years failed. ... We investigated several VLBI CPO series by means of spectral and wavelet analysis. It has been shown that there are several periodic signals with close amplitude around the expected FICN period without any prevailing one that can be reliably associated with the FICN. ...

... In the presence of only uniform magnetic field B , the motion of a charged particle can be described with gyration about the guiding center and motion along the field line. ... In the precence of both magnetic and electric fields, the equation of motion for charged particle (mass m, charge q) is m d v /dt = q ( E + v x B ). ... Because v is independent of the mass and sign of the charge, it is the same for negatively and positively charged particles, and does not create electric current. ...

... Microlocal Analysis is a theory of Pseudo-Differential Operators and Fourier Integral Operators (PDOs and FIOs). ... Microlocal analysis comes in few flavors. ... We will consider semi-classical PDOs and FIOs: one can always get from there to standard PDOs and FIOs but semi-classical theory has more applications. Less formal description of (semi-classical) microlocal analysis is ``a semi-classical limit of quantum mechanics'' or ``high-frequency limit of electrodynamics'' (etc). ...
