摘要： An information processing system is provided. The information processing system includes first and second information processors. The first information processor obtains a first moving image including a face and detecting an eye from two or more first images among the first moving image. The first information processor detects a pupil from the eye detected from the first image, calculating its size, and performing learning using a change over time in the size of the pupil. The second information processor obtains a second moving image including a face and detecting an eye from two or more second images among the second moving image. The second information processor detects a pupil from the eye detected from the second image, calculating its size, and performing inference on the change over time in the size of the pupil on the basis of the result of the learning performed by the first information processor.

摘要： To increase the conductivity and electric capacity of an electrode which includes active material particles and the like and is used in a battery, a graphene net including 1 to 100 graphene sheets is used instead of a conventionally used conduction auxiliary agent and binder. The graphene net which has a two-dimensional expansion and a three-dimensional structure is more likely to touch active material particles or another conduction auxiliary agent, thereby increasing the conductivity and the bonding strength between active material particles. This graphene net is obtained by mixing graphene oxide and active material particles and then heating the mixture in a vacuum or a reducing atmosphere.

摘要： To form graphene to a practically even thickness on an object having an uneven surface or a complex surface, in particular, an object having a surface with a three-dimensional structure due to complex unevenness, or an object having a curved surface. The object and an electrode are immersed in a graphene oxide solution, and voltage is applied between the object and the electrode. At this time, the object serves as an anode. Graphene oxide is attracted to the anode because of being negatively charged, and deposited on the surface of the object to have a practically even thickness A portion where graphene oxide is deposited is unlikely coated with another graphene oxide. Thus, deposited graphene oxide is reduced to graphene, whereby graphene can be formed to have a practically even thickness on an object having surface with complex unevenness.
