Perhaps you should try some spelling variations:
modulation parameters » population parameters (Expand search), coagulation parameters (Expand search), formulation parameters (Expand search)
based programming » and programming (Expand search), based program (Expand search), cone programming (Expand search)
their modulation » the modulation (Expand search), their education (Expand search), their correlation (Expand search)
parameters based » parameters and (Expand search), parameters after (Expand search), parameters by (Expand search)
using rotating » in rotating (Expand search)
rotating in » rotating ring (Expand search), rotating twin (Expand search), rotating spin (Expand search)
in python » _ python (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( their modulation parameters based programming ) OR ( using rotating in python programming ))~.
