Perhaps you should try some spelling variations:
communication time » communication tower, communication tool, communication optimal
time dimension » five dimension, three dimension, five dimensions
array forming » array format, array arcing, array formats
array strong » array string, array sharing, norway strong
array fermi » array format

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

• Performing a fuzzy search may retrieve terms with similar spellings: communication communication time dimension ((array strong) or (((array forming) OR (array fermi))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: communication communication time dimension ((array strong) OR (((array forming) OR (array fermi)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication communication time dimension ((array strong) or (((array forming) OR (array fermi))))".
• Adding a wildcard symbol may retrieve word variants: communication communication time dimension ((array strong) or (((array forming) OR (array fermi))))*.
