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: An embodiment device includes an input module including a motor configured to generate a rotational force, an output module configured to receive power from the input module to be rotatable, and a connection module having a first side coupled to the input module and a second side, opposite the first side, coupled to the output module, wherein the connection module is configured to transmit the power from the input module to the output module.

Abstract: Disclosed is a focused ultrasound operation apparatus that includes: an operation hand piece that includes a handle unit that is used as a handle for a user; a cartridge that includes an ultrasound treatment unit, which generates a focused ultrasound, and has the shape of a circular cylinder or bar, the cartridge being attached to, and detached from, the operation hand piece; a window provided on the cartridge to pass the focused ultrasound generated by the ultrasound treatment unit; and a driver that drives the ultrasound treatment unit to move the ultrasound treatment unit forward and backward.

Abstract: The present disclosure relates a focused ultrasound operation apparatus suitable for providing a controllable rotation angle. The focused ultrasound operation apparatus includes: a handpiece provided for manipulation by an operator; a cartridge of a body-insertion type which is detachably coupled to the handpiece and includes an ultrasound emitting portion. In particular, the handpiece includes: a rotation module portion provided for the operator to rotate the cartridge coupled to the handpiece; a case arranged outside the rotation module portion; and a cartridge rotation angle adjustor to adjust a rotation angle of the cartridge with respect to a rotation motion around a center axis in a body-insertion direction of the cartridge, interacting with a rotation of the rotation module portion.
