Perhaps you should try some spelling variations:
"modified adamdamdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified adamdamdaptive estimation algorithm"
"modified orcad convolution algorithms" » "modified orcad evolution algorithm", "modified orcad solution algorithm", "modified orca 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 adamdamdaptive quantization algorithm") OR ("modified orcad convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified adamdamdaptive quantization algorithm ) or ( modified orcad convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adamdamdaptive quantization algorithm") or ("modified orcad convolution algorithms"))*.
