When the dynamics of a spatially distributed excitable or oscillatory medium is complex, synchronization defect lines may exist which lead to a variety of pattern formation processes. If a medium with period-n local dynamics supports spiral waves, such synchronization defect lines are necessary to reconcile the fact that n rotations of a spiral wave are needed to restore the entire concentration field to its initial value. We show how such synchronization defect lines may be classified and how they can lead to line-defect turbulent states through non-equilibrium phase transitions. © 2000 American Institute of Physics.

    To compensate the time synchronisation error, the direct-path signal is used in some bistatic synthetic aperture radar (BiSAR) systems. It turns out that an additional error is added in the translational-variant BiSAR echo data when the direct-path signal is directly used to compensate the time...
