Perhaps you should try some spelling variations:
information function » information fusion, information section, information nation
surface diffusion » state diffusion
function surface » functional surface, functions surfaces, friction surface
array sharing » arrays bearing, array imaging, way sharing
array string » array strong, arrays strings, array forming
array using » arrays using

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 function surface diffusion ((array using) OR (((array sharing) OR (array string))))~.
• Adding a wildcard symbol may retrieve word variants: information function surface diffusion ((array using) or (((array sharing) or (array string))))*.
