Perhaps you should try some spelling variations:
mass transport » gas transport, mass transit, bus transport
transform test » transform teams, transform tvdft, transform fft
transport a » transport _, transport data
co wavelet » _ wavelet, 4 wavelet, a wavelet
areas co » areas coal, areas act, areas can
guias de » guia de, guide de, aguas de
de mass » de masse, de mais, de masa
a ao » a a, a co, a o

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 co wavelet transform test _ ) OR ( guias de mass transport a ao ))~.
• Adding a wildcard symbol may retrieve word variants: (( areas co wavelet transform test _ ) or ( guias de mass transport a ao ))*.
