A New Phase Sequence Exchanging Control Method for Reducing Impulse Current and Voltage
Phase sequence exchanging technology (PSET) is a recently developed emergency control technology for out-of-step power systems. The PSET system does not satisfy the condition of synchronization however, and will produce impulse current and impact torque.

IMPULSE WAVES GENERATED BY LANDSLIDES
A study programme has been initiated to investigate the impulse waves generated by landslides originating entirely above the water surface It may be seen that the characteristics of this wave depend mainly on the slide volume and the Froude number of the slide upon impact with the water The resulting wave goes through a transition period For the ...

Generalized impulse response analysis: General or Extreme? [PDF]
This note discusses a pitfall of using the generalized impulse response function (GIRF) in vector autoregressive (VAR) models (Pesaran and Shin, 1998). The GIRF is general because it is invariant to the ordering of the variables in the VAR. The GIRF, in fact, is extreme because it yields a set of response functions that are based on extreme identifying
