Perhaps you should try some spelling variations:
innovation implementation » formulation implementation
implementation progress » implementation process, implementation program, implementation problems
concepts critiques » concepts critical
progress creating » process creating, problems creating, program creating
concepts circuits » converter circuits, concepts chris, controls circuits

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: innovation implementation progress creating ((concepts circuits) OR (concepts critiques))~.
• Adding a wildcard symbol may retrieve word variants: innovation implementation progress creating ((concepts circuits) or (concepts critiques))*.
