Perhaps you should try some spelling variations:
transforms signal » transform signal
borel transforms » fourier transforms, other transforms, l transforms
large transfer » large transfers, barge transfer, wage transfer
cnn borel » cnn model, rn borel
page cnn » page c
signal 4 » signal _, signal 3, signal 6
guias do » guia do, guias de, guia de
do large » so large, done large, how large

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: (( page cnn borel transforms signal 4 ) OR ( guias do large transfer _ case ))~.
• Adding a wildcard symbol may retrieve word variants: (( page cnn borel transforms signal 4 ) or ( guias do large transfer _ case ))*.
