solutions [phi] satisfy the advance-delay equation
The stator utilizes two 3rd-order bending modes in the section plane as working modes to form a travelling wave
. The thread contact pair between the rotor and stator then transforms the rotation of the rotor into helical motion (linear and synchronous rotation).
The first observation in  is that travelling wave
solutions of the general class (2) with power nonlinearities exist for two different regimes.
If there is a nonincreasing travelling wave
W(c; [theta], x - ct) with W(c; [theta], [infinity]) = 0 and W(c; [theta], -[infinity]) = [beta], then c [greater than or equal to] [c.sup.*].
More specifically, in this paper we are looking for travelling wave

It has been shown that chemotaxis does not influence the existence of travelling wave
solutions (see, e.g., ).
Zitterbart said that he was really surprised to learn that a travelling wave
can be triggered by any penguin in a huddle rather than penguins on the outside trying to push in.
The time stamps are fixed at the travelling wave
SWAs may operate in standing or travelling wave
mode and the slots used are called resonant or non-resonant slots, respectively.
18 May 2012 a[euro]" Swiss-based EMC test solutions provider Teseq Holding AG said it was in the process of acquiring Instruments for Industry (IFI), a US company engaged in the production of RF microwave, solid state and travelling wave
tube (TWT) amplifiers.
