Perhaps you should try some spelling variations:
"size segment structure analysis" » "size segment structural analysis", "size segmental structure analysis", "size sediment structure analysis", "size pigment structure analysis", "five segment structure analysis", "pipe segment structure analysis"
"line segment across analysis" » "line segment cross analysis", "line segment access analysis", "line segment across analytic", "line segments cross analysis", "line segment ros analysis", "line segments across 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: (("size segment structure analysis") OR ("line segment across analysis"))*.
• Removing quotes may allow a broader search: (( size segment structure analysis ) or ( line segment across analysis ))*.
