Perhaps you should try some spelling variations:
"modified adamfdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified adamfdaptive 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"

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