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.

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