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