Perhaps you should try some spelling variations:
structure functions » structure function
data dimensions » data dimension, data dimensional, dark dimensions
functions data » functional data
array linear » array nonlinear, array library, delay linear
ray driven » brand driven
pixels » pixel

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

• Performing a fuzzy search may retrieve terms with similar spellings: structure functions data dimensions ((((array linear) or (ray driven))) or (array pixels))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: structure functions data dimensions ((((array linear) OR (ray driven))) OR (array pixels)).
• Adding a wildcard symbol may retrieve word variants: structure functions data dimensions ((((array linear) or (ray driven))) or (array pixels))*.
