Perhaps you should try some spelling variations:
"modified passive ventilation algorithms" » "modified passive estimation algorithms", "modified passive estimation algorithm", "modified passive convolution algorithms", "modified invasive ventilation algorithms"
"modified adaptive ventilation algorithms" » "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified adaptive convolution algorithms", "modified adaptive quantization algorithms", "modified invasive ventilation 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 passive ventilation algorithms") or ("modified adaptive ventilation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified passive ventilation algorithms") OR ("modified adaptive ventilation algorithms")).
• Removing quotes may allow a broader search: (( modified passive ventilation algorithms ) or ( modified adaptive ventilation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified passive ventilation algorithms") or ("modified adaptive ventilation algorithms"))*.
