Abstract: An apparatus for predicting performance of a wheel in a vehicle: includes a learning device that generates a latent space for a plurality of two-dimensional (2D) wheel images based on a convolutional autoencoder (CAE), extracts a predetermined number of the plurality of 2D wheel images from the latent space, and learns a dataset having the plurality of 2D wheel images and performance values corresponding to the plurality of 2D wheel images; and a controller that predicts performance for the plurality of 2D wheel images based on a performance prediction model obtained by the learning device.

Abstract: A paper coating composition, methods for making the same, and a coated paper. The paper coating composition comprises a solvent, an ethylene-(meth)acrylic acid copolymer, a basic compound, and a polycarbodiimide-based curing agent, wherein the polycarbodiimide-based curing agent has a carbodiimide group equivalent of about 150 to about 350. The coating of the coated paper likewise comprises an ethylene-(meth)acrylic acid copolymer crosslinked by N-acylurea groups.

Abstract: A flow tube connection module and a water purifier including the same are provided. The flow tube connection module includes a housing having a coupling space in which a first flow tube and a second flow tube are connected to each other; a tube connecting member provided in the coupling space and connecting the first flow tube and the second flow tube to each other; an enlarged coupling portion provided in the housing; a coupling body coupled to the enlarged coupling portion to connect a plurality of the housings; and a separation prevention cover or a connection release member assisting the first flow tube in being connected to or separated from the tube connecting member.

Abstract: Disclosed is a method for production of hydrogen energy utilizing silicon wastewater. The method includes treating the silicon wastewater through UF membrane filtration to separate UF treated water and a concentrated silicon waste solution therefrom, admixing the separated silicon waste solution with an alkaline material, reacting the concentrated silicon waste solution with the alkaline material in the mixture to produce hydrogen gas and alkaline water, using an acidic material to neutralize the alkaline water, thereby forming a supernatant and a precipitate.

Abstract: Disclosed are a hydrogen energy production system utilizing silicon wastewater and a method for production of hydrogen energy using the same. More particularly, the disclosed system includes: a UF treatment bath wherein the silicon wastewater is treated through UF film filtration to separate UF treated water and a concentrated silicon waste solution therefrom; a line mixer connected to the UF treatment bath in order to admix the separated silicon waste solution with an alkaline material fed from the outside; and a hydrogen production bath connected to the line mixer, wherein the concentrated silicon waste solution in the mixture reacts with the alkaline material, in order to produce hydrogen gas. Additionally, a hydrogen energy production method using the foregoing system is also disclosed.
