Perhaps you should try some spelling variations:
transform tvdft » transform test
transform fft » transform cote, transform test, transform _
transfer 4 » transfer _, transfer 3, transfer a
areas can » areas case, areas cash, areas coal
can ideas » las ideas, own ideas, un ideas
guias de » guia de, guide de, aguas de
heat » head

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 can ideas ((transform fft) OR (transform tvdft)) 4.5 ) OR ( guias de heat transfer 4 a ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas can ideas ((transform fft) OR (transform tvdft)) 4.5 ) or ( guias de heat transfer 4 a ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas can ideas ((transform fft) OR (transform tvdft)) 4.5 ) or ( guias de heat transfer 4 a ))*.
