Perhaps you should try some spelling variations:
communication implementation » communication implementations, communications implementation, communication implementing
computation implementation » computational implementation, population implementation, formulation implementation
dimensional images » dimensional image, dimensional imaging, dimensional climate
any dimensional » many dimensional, one dimensional, n dimensional
images sparse » images space, images part, images scale

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((communication implementation) or (computation implementation)) any dimensional images sparse~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((communication implementation) OR (computation implementation)) any dimensional images sparse.
• Adding a wildcard symbol may retrieve word variants: ((communication implementation) or (computation implementation)) any dimensional images sparse*.
