Perhaps you should try some spelling variations:
"based analytical measurement" » "based analysis measurement", "based clinical measurement", "based analysis measurements"
"acid optical measurement" » "acid optical measurements", "acid physical measurements", "acid inertial measurement", "aged optical measurement", "grid optical measurement", "based optical measurement"
"rapid optical measurement" » "rapid optical measurements", "rapid physical measurements", "rapid inertial measurement"
"rapid medical measurement" » "rapid medical measurements", "rapid media measurement", "rapid biomedical measurement", "rapid chemical measurement"

Try widening your search to All Fields.

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: (("based analytical measurement") OR ((("acid optical measurement") OR ((("rapid optical measurement") OR ("rapid medical measurement")))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"based analytical measurement\") or (((\"acid optical measurement\") or (((\"rapid optical measurement\") OR (\"rapid medical measurement\"))))))".
• Removing quotes may allow a broader search: (( based analytical measurement ) or ((( acid optical measurement ) or ((( rapid optical measurement ) OR ( rapid medical measurement )))))).
• Adding a wildcard symbol may retrieve word variants: (("based analytical measurement") or ((("acid optical measurement") or ((("rapid optical measurement") OR ("rapid medical measurement"))))))*.
