Perhaps you should try some spelling variations:
information propagation » information presentation, information organization
propagation help » propagation delay, propagation awp, propagation de
help dimension » new dimension, high dimension, de dimension
array sharing » arrays bearing, array imaging, way sharing
array string » array strong, arrays strings, array forming
array fermi » array forming, array format

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: information propagation help dimension ((((array string) OR (array fermi))) OR (array sharing))~.
• Adding a wildcard symbol may retrieve word variants: information propagation help dimension ((((array string) or (array fermi))) or (array sharing))*.
