Perhaps you should try some spelling variations:
"modified passive quantization algorithm" » "modified passive estimation algorithm", "modified adaptive quantization algorithm"
"modified charging estimation algorithms" » "modified charging estimation algorithm", "modified charging optimization algorithms", "modified charging optimisation algorithm", "modified charging station algorithms", "modified caging estimation algorithms", "modified carbon estimation 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 quantization algorithm") OR ("modified charging estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified passive quantization algorithm\") OR (\"modified charging estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified passive quantization algorithm ) OR ( modified charging estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified passive quantization algorithm") OR ("modified charging estimation algorithms"))*.
