Talvez debería tentar con algunhas variantes ortográficas:
information ground » information grounds, information group, information grid
surface diffusion » state diffusion
ground surface » road surface, rough surface, ground source
array sharing » array string, arrays bearing, array imaging
array forming » array format, array fermi, array formats
array arcing » array probing, array using, array along

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 ground surface diffusion ((((array arcing) OR (array sharing))) OR (array forming))~.
• Adding a wildcard symbol may retrieve word variants: information ground surface diffusion ((((array arcing) or (array sharing))) or (array forming))*.
