The improvement in accuracy and efficiency of wave-equation migration techniques is an ongoing topic of research. The main problem is the correct imaging of steeply dipping reflectors in media with strong lateral velocity variations. We propose an im

In einer groseren Brutkolonie des Eleonorenfalken der Agais siedeln sich die Mannchen relativ nahe am Geburtsrevier an (mittlere Ansiedlungsentfernung 192 ± 153 m); die Weibchen zeigen eine etwas grosere Dispersion (Ansiedlungsentfernung 738 ± 1104

Films of WBx have been deposited on silicon and GaAs substrates from a compound target using an r.f. magnetron sputtering system to investigate the structural properties. A substrate bias has been applied to vary the deposition and film properties. E

A co-sputtering process is characterized which allows the deposition of WSi0.4 layers for Schottky gates of GaAs self-aligned MESFETs. The process parameters were optimized to yield films with low stress, good adhesion and a high interface stability

In regions of complex geology, the corresponding seismic time sections show diffraction events, distorted positions of reflectors, smeared lateral discontinuities and uncertain amplitudes of seismic reflections with the consequence that the interpret

Full 3-D prestack depth migration (one-pass migration) is in principle an effective way to image complex 3-D structures with significant lateral vetocity variations.
