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

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

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