Perhaps you should try some spelling variations:
communication applications » communication education, education applications
applications first » applications fast, applications from
first dimension » first division, fifth dimension, first impression
array probing » arrays probing, assay probing, array profiling
array using » arrays using
array ang » arrays ang, array along, array range

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 first dimension ((array ang) OR (((array using) OR (array probing))))~.
• Adding a wildcard symbol may retrieve word variants: communication applications first dimension ((array ang) or (((array using) or (array probing))))*.
