Perhaps you should try some spelling variations:
"modified adaptive convolution algorithms" » "modified adaptive evolution algorithm", "modified adaptive solution algorithm", "modified adaptive construction algorithms", "modified adaptive ventilation algorithms", "modified passive convolution algorithms"
"modified invasive ventilation algorithm" » "modified invasive estimation algorithm", "modified invasive estimation algorithms", "modified invasive evolution algorithm", "modified adaptive ventilation algorithm", "modified passive ventilation algorithm"

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: (("modified adaptive convolution algorithms") OR ("modified invasive ventilation algorithm"))~.
• Removing quotes may allow a broader search: (( modified adaptive convolution algorithms ) or ( modified invasive ventilation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive convolution algorithms") or ("modified invasive ventilation algorithm"))*.
