Perhaps you should try some spelling variations:
transform power » transform primer, transform your, transform our
haar transform » can transform, data transform, make transform
transform fair » transform pairs, transform haar, transform family
power 6 » power _, power a
de case » de cause, ode case, pde case
fair a » fair ai, fair _, fair 4

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: (( guias _ haar transform power 6 ) OR ( guias ((de cas) OR (de case)) transform fair a ))~.
• Adding a wildcard symbol may retrieve word variants: (( guias _ haar transform power 6 ) or ( guias ((de cas) or (de case)) transform fair a ))*.
