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