Perhaps you should try some spelling variations:
layered transform » lamperti transform, wavelet transform, leaders transform
transform tvdft » transform fft, transform test
mais transfer » mass transfer, gas transfer, mit transfer
two layered » two layer
areas two » areas co
guias des » guias de, guia de, bias des
des mais » de mais, des fais, des pais
3 ao » 3 a, 3 co, 3 ai
3 do » _ do, 3 d, 1 do

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 layered transform tvdft a ) OR ( guias des mais transfer ((3 ao) OR (3 do)) ))~.
• Adding a wildcard symbol may retrieve word variants: (( areas two layered transform tvdft a ) or ( guias des mais transfer ((3 ao) or (3 do)) ))*.
