Perhaps you should try some spelling variations:
"advanced computation of loading program" » "advanced computations of loading program" (Expand search), "advanced computational of loading program" (Expand search), "advance computational of loading program" (Expand search), "advanced computation of reading program" (Expand search), "advanced computation of breading program" (Expand search), "advanced computation of reading programs" (Expand search)
"using computation _ precoder program" » "using computational _ precoder program" (Expand search), "using imputation _ precoder program" (Expand search), "using compilation _ precoder program" (Expand search), "using computation _ proder program" (Expand search), "using computation _ recovery program" (Expand search), "using computation _ precoce programa" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("advanced computation of loading program") OR ("using computation _ precoder program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"advanced computation of loading program\") OR (\"using computation _ precoder program\"))".
• Removing quotes may allow a broader search: (( advanced computation of loading program ) OR ( using computation _ precoder program )).
• Adding a wildcard symbol may retrieve word variants: (("advanced computation of loading program") OR ("using computation _ precoder program"))*.
