Perhaps you should try some spelling variations:
"modified adaptive estimation algorithmss" » "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified adaptive optimization algorithms", "modified adaptive ventilation algorithmss", "modified quantile estimation algorithmss", "modified adaptive quantization algorithmss", "modified passive estimation algorithmss"
"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 invasive ventilation algorithm") OR ("modified adaptive estimation algorithmss"))~.
• Removing quotes may allow a broader search: (( modified invasive ventilation algorithm ) or ( modified adaptive estimation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified invasive ventilation algorithm") or ("modified adaptive estimation algorithmss"))*.
