Perhaps you should try some spelling variations:
"Computer-timed designs" » "Computer-timed design", "Computer-aided designs", "Computer-time design"
"computer-aimed design" » "computer-timed design", "computer-mixed design", "computer-fixed design"
"computer-aided design" » "computer-added design"

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: (("computer-aided design") OR ((("computer-aimed design") OR ("Computer-timed designs")))).
• Removing quotes may allow a broader search: (( computer-aided design ) or ((( computer-aimed design ) or ( Computer-timed designs )))).
• Adding a wildcard symbol may retrieve word variants: (("computer-aided design") or ((("computer-aimed design") or ("Computer-timed designs"))))*.
