The ability to efficiently and sparsely represent seismic data is becoming an increasingly important problem in geophysics. Over the last 30 years many transforms such as wavelets, curvelets, contourlets, surfacelets, shearlets, and many other types ofx- lets have been developed. Such transform were leveraged to resolve this issue. In this work we compare the properties of four of these commonly used transforms, namely the shift-invariant wavelets, complex wavelets, curvelets and surfacelets. We also explore the performance of these transforms for the problem of recovering seismic wavefields...

This text is an advancement of the theory of vibration protection of mechanical systems with lumped and distributed parameters. The book offers various concepts and methods of solving vibration protection problems, discusses the advantages and disadvantages of different methods, and the fields of their effective applications.
Fundamental approaches of vibration protection, which are considered in this book, are the passive, parametric and optimal active vibration protection. The passive vibration protection is based on vibration isolation, vibration damping and dynamic absorbers....
