Two-layered speaker classification using dynamic bayesian networks.

The specification discloses an apparatus and method for molding glass fiber reinforced polyester resin articles. A bladder-covered male mold is in turn covered with resin and reinforcement and a female mold with a surface forming film located therein or with a smooth surface is then closed over the male mold. With the bladder held against the male mold by vacuum, air is evacuated from between the bladder and the female mold. The vacuum between the bladder and the male mold is then released whereby the bladder is forced against the resin to thereby force it against the film which is located within the female mold or against the mold surface. This insures a molded article with a bubble free surface. Where a film is used, this insures a tight air free bond between the resin and the film.
