Perhaps you should try some spelling variations:
functions conditional » functions functional, functional conditioning, functions computational
conditional spatial » conditions spatial, conventional spatial, traditional spatial
spatial dimensions » social dimensions, social dimension, political dimensions
array devicen » array devices, airway devices, array design
array device » airway devices, array design, array drive
array pixel » array pixels

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: functions conditional spatial dimensions ((((array devicen) OR (array device))) OR (array pixel))~.
• Adding a wildcard symbol may retrieve word variants: functions conditional spatial dimensions ((((array devicen) or (array device))) or (array pixel))*.
