Perhaps you should try some spelling variations:
"life patient features analysis" » "life patient feature analysis", "life patient measures analysis", "life patients features analysis", "life salient features analysis", "life latent features analysis", "life patterns features analysis", "life pain features analysis"
"pipe segment content analysis" » "pipe segment sentiment analysis", "pipe segment component analysis", "pipe segment element analysis", "pipe cement content analysis", "pipe pigment content analysis", "pipe segment concept analysis", "pipe segments content analysis", "line segment content analysis", "five segment content analysis"

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: (("life patient features analysis") OR ("pipe segment content analysis"))*.
• Removing quotes may allow a broader search: (( life patient features analysis ) or ( pipe segment content analysis ))*.
