Perhaps you should try some spelling variations:
estimation detection » estimation detecting, respiration detection, activation detection
detection methods » detection method, extraction methods, collection methods
methods tables » methods tools, methods problems, methods examples
array string » array strong, arrays strings, array sharing
array using » arrays using

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "estimation detection methods tables ((((array string) OR (array format))) OR (array using))~".
• Adding a wildcard symbol may retrieve word variants: estimation detection methods tables ((((array string) OR (array format))) OR (array using))*.
