  coherent processing
The experimental data collected in the course of automated ultrasonic testing (AUT) using Avgur series with coherent processing of data (Avgur 4.2 and Avgur 5 systems) and the results of the assessment of nondestructive testing data are used.
      
By multiple-bursts coherent processing, the HRR profile synthesis, target velocity compensation and clutter compression can be accomplished simultaneously.
      
The setup presented is suited for the controlled coherent processing of atomic and photonic quantum information.
      
Another option being investigated is coherent processing of the multi-path data for greatly enhanced resolution.
      
Figure 11 and Figure 12, shows the overhead, latency and scalability of the algorithm for coherent processing.

  coherent process
Formation of photorhodopsin within 200 fsec was observed by a transient absorption (pump-probe) experiment, which also revealed that the photoisomerization in rhodopsin is a vibrationally coherent process.
      
Insufficiency of a semiclassical description of this coherent process in excited media with the use of the unique tensor index of refraction is shown to follow from quantum electrodynamics.
      
Good agreement between model predictions and the data was found for the coherent process.
      
Atomic absorption can be a coherent process, which depends on the relative amplitude, phase and intersection angle of coherent beams.
      
An organiza tional unit deploys one or more processes that have a coherent process context and operates within a coherent set of business ob jectives.

The coherent processing of 3-D seismic data in Xinchang,Dongtai and Hexingchang areas was achieved by using 3-D coherent technique. The result analysis says that the discontinuity of fault of formation characteristic may be shown very clearly by the low coherence anomaly of coherent 3-D seismic data volumes while continuity of formation characteristic is exhibited very obviously by high coherence anomaly of coherent 3-D data volumes. As a result,coherent technique of 3-D seismic data volume has become one of...
