transform cities » transforming cities, transform cote, transform coding
transform crisis » transfer crisis, transport crisis, transform pairs
haar transform » can transform, data transform, make transform
cities la » cities a, cities can, cities dar
aguas do » aguas de, aguas del
crisis a » crisis _
