Perhaps you should try some spelling variations:
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"
"modified qoe estimation algorithms" » "modified qoe estimation algorithm", "modified qoe optimization algorithms", "modified qoe optimisation algorithm", "modified pose estimation algorithms", "modified _ estimation algorithms", "modified cover estimations algorithms", "modified male estimation algorithms", "modified bi1 estimation algorithms"

Try widening your search to All Fields.

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 quantization algorithm") or ("modified qoe estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive quantization algorithm") OR ("modified qoe estimation algorithms")).
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithm ) or ( modified qoe estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive quantization algorithm") or ("modified qoe estimation algorithms"))*.
