... The concepts of Fourier frequency and wavelet duration are obviously related. ... Among many sensible definitions, we chose to require that the peak of the wavelet mean spectrum should be matched with the singularity of the Fourier transform of the cosine wave. Then, it can be shown that the frequency of the cosine is related to the wavelet duration by the relation . ... The ambiguous definition of the duration of an event is common to the sizing of any object of irregular shape. ...

The results will be vital for reclassifying GSC objects. ... Many objects are measured on more than one plate, and thus have multiple catalog entries. ... Among the shortcomings of the GSC are: biased magnitudes and incorrect classifications for certain objects, presence of artifact objects. ...

In the early 1980s, our understanding of binary star evolution љ based on the pioneer work by Paczynski (1971)[ 150 ], Tutukov and Yungelson (1973)[ 195 ], van den Heuvel and Heise (1972)[ 201 ], allowed us to construct a general evolutionary scenario љ which successfully explained the genesis of well-studied normal stars and offered potential explanation for new X-ray sources discovered in space experiments. ...
