Perhaps you should try some spelling variations:
"modified invasive ventilation algorithms" » "modified invasive estimation algorithm", "modified invasive convolution algorithms", "modified adaptive ventilation algorithms", "modified passive ventilation algorithms"
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified motion estimation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified notion estimation algorithms") or ("modified invasive ventilation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified notion estimation algorithms") OR ("modified invasive ventilation algorithms")).
• Removing quotes may allow a broader search: (( modified notion estimation algorithms ) or ( modified invasive ventilation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified notion estimation algorithms") or ("modified invasive ventilation algorithms"))*.
