Perhaps you should try some spelling variations:
computations using » populations using (Expand search), computations in (Expand search), communications using (Expand search)
by computations » by computational (Expand search), of computations (Expand search), by computacional (Expand search)
coating pitons » coating pathogens (Expand search)
using coating » using coatings (Expand search), using rotating (Expand search), using cutting (Expand search)
peg program » pg program (Expand search), bag program (Expand search), dog program (Expand search)
using peg » using pet (Expand search), using pcr (Expand search), using p (Expand search)

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

• Removing quotes may allow a broader search: (( by computations using peg program ) OR ( using coating pitons python programming ))*.
