Perhaps you should try some spelling variations:
communication control » communication concepts, communication culture, communication channel
mixed precision » based precision, dies precision, model precision
fixed precision » based precision, dies precision, finite precision
data solving » data resolving, data evolving, data moving
data mapping » data mining, a mapping

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 control ((mixed precision) OR (fixed precision)) ((data solving) OR (data mapping))~.
• Adding a wildcard symbol may retrieve word variants: communication control ((mixed precision) or (fixed precision)) ((data solving) or (data mapping))*.
