Perhaps you should try some spelling variations:
"covariance function and feeding program" » "covariance functions and feeding program" (Expand search), "ovarian function and feeding program" (Expand search)
"advanced modulation coding decoding program" » "advanced calculation coding decoding program" (Expand search), "advanced oxidation coding decoding program" (Expand search), "advanced population coding decoding program" (Expand search), "advanced modulation welding decoding program" (Expand search), "advanced modulation during decoding program" (Expand search), "advanced modulation coding welcoming program" (Expand search), "advanced modulation coding deworming program" (Expand search), "advanced modulation coding reading program" (Expand search), "advanced modulation encoding decoding program" (Expand search), "advanced modulation reading decoding program" (Expand search), "advanced modulation joint decoding program" (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"covariance function and feeding program\") OR (\"advanced modulation coding decoding program\"))~".
• Removing quotes may allow a broader search: (( covariance function and feeding program ) OR ( advanced modulation coding decoding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("covariance function and feeding program") OR ("advanced modulation coding decoding program"))*.
