Perhaps you should try some spelling variations:
communication applications » communication education, education applications
from dimension » flow dimension, first dimension, forms dimension
array imaging » arrays imaging, airway imaging, ray imaging
array arcing » array forming, array probing, array sharing
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 from dimension ((((array ang) OR (array imaging))) OR (array arcing))~.
• Adding a wildcard symbol may retrieve word variants: communication applications from dimension ((((array ang) or (array imaging))) or (array arcing))*.
