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