  • Publication number: 20190205334
    Abstract: A generative adversarial networks-based or GAN-based method for learning cross-domain relations is disclosed. A provided architecture includes two coupled GANs: a first GAN learning a translation of images from domain A to domain B, and a second GAN learning a translation of images from domain B to domain A. A loop formed by the first GAN and the second GAN causes sample images to be reconstructed into an original domain after being translated into a target domain. Therefore, loss functions representing reconstruction losses of the images may be used to train generative models.

  • Publication number: 20180277872
    Abstract: Disclosed are a process for separating an electrode for membrane-electrode assemblies of fuel cells from the decal transfer film and an apparatus for separating the electrode. In particular, during the electrode separating process, only an electrode is separated from the decal transfer film on which the electrode is coated, without any damage, by a freezing method for freezing the specimen on the deionized water surface, and thus, wasting the expensive MEA is prevented. Thus, mechanical properties of the pristine electrode can be rapidly quantified in advance, and therefore, long term durability evaluation period during developing MEA having excellent durability is substantially reduced.
