Perhaps you should try some spelling variations:
"d analytical measurement" » "d analysis measurement", "d clinical measurement", "d analysis measurements", "8 analytical measurement", "9 analytical measurement", "2.2 analytical measurement"
"acid optical measurement" » "acid optical measurements", "acid physical measurements", "rapid optical measurement", "aged optical measurement", "grid optical measurement"
"d inertial measurement" » "3d inertial measurement", "_ inertial measurement", "3 inertial 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: (((("d analytical measurement") OR ("d inertial measurement"))) OR ("acid optical measurement")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"d analytical measurement\") OR (\"d inertial measurement\"))) or (\"acid optical measurement\"))".
• Removing quotes may allow a broader search: (((( d analytical measurement ) OR ( d inertial measurement ))) or ( acid optical measurement )).
• Adding a wildcard symbol may retrieve word variants: (((("d analytical measurement") OR ("d inertial measurement"))) or ("acid optical measurement"))*.
