Perhaps you should try some spelling variations:
communication applications » communication education, education applications
applications basic » applications based, applications business
basic dimension » basic dimensions, based dimension, based dimensions
array ang » array along, array range, array nano
arrays a » arrays _

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: communication applications basic dimension ((array ang) OR (((arrays ang) OR (arrays a))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "communication applications basic dimension ((array ang) or (((arrays ang) OR (arrays a))))~".
• Adding a wildcard symbol may retrieve word variants: communication applications basic dimension ((array ang) or (((arrays ang) OR (arrays a))))*.
