Perhaps you should try some spelling variations:
communication functions » communicative functions, communication foundations, communication foundation
based dispersion » wave dispersion, gas dispersion, based discussion
functions based » function based
arrays probing » array probing, rays probing, arrays producing
array string » array strong, arrays strings, array sharing
arrays a » arrays _

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication functions based dispersion ((((array string) or (arrays probing))) or (arrays a))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication functions based dispersion ((((array string) OR (arrays probing))) OR (arrays a)).
• Adding a wildcard symbol may retrieve word variants: communication functions based dispersion ((((array string) or (arrays probing))) or (arrays a))*.
