Perhaps you should try some spelling variations:
transform set » transform test, transform fft, transform std
mass transfer » cash transfer, basin transfer, mass transport
two wavelet » two wavelength, from wavelet
transfer a » transfer _, transfer 3, transfer 4
areas two » areas co
guias de » guia de, guide de, aguas de
de mass » de masse, de mais, de masa
set a » set _, get a

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: (( areas two wavelet transform set a ) OR ( guias de mass transfer a la ))~.
• Adding a wildcard symbol may retrieve word variants: (( areas two wavelet transform set a ) or ( guias de mass transfer a la ))*.
