Talvez debería tentar con algunhas variantes ortográficas:
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 arcing » array forming, array probing, array sharing

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: estimation detection methods tables ((((array string) OR (array format))) OR (array arcing))~.
• Adding a wildcard symbol may retrieve word variants: estimation detection methods tables ((((array string) or (array format))) or (array arcing))*.
