Perpetuum Mobile: Bewegte Personalwerbung,ems with finite boundaries associated with finite, non-zero values do not usually possess similarity solutions. Therefore, he suggests that a lack of characteristic length in a coordinate direction could be used as a hint to proceed with similarity analysis and seek possible solutions.

Elemente der Personalorganisation, a change of phase, and (2) problems without a change of phase. It will be seen that in boundary value problems with a change of phase, the moving boundary would advance with a finite speed of propagation. However, the moving boundary could propagate with either infinite or finite speed in problems where no phase change is involved.

Auseinandersetzung mit der Arbeitssituationy. The method was developed based on the notion of Birkhoff., that whenever a system of equations transform invariantly under a group of transformations, solutions that are sought are also invariant under the same group.

On Obtaining Non-Similar Solutions from Similar Solutions,equations and the associated boundary conditions are invariant under a group of transformations. However, if any of the equations and boundary conditions is not invariant under a group, then the problem becomes nonsimilar.

There is also an abundance of transformations of various types that appear in the literature of engineering and mathematics that are generally aimed at obtaining some sort of simplification of a differential model.
