Abstract: Disclosed is a beamforming method using a deep neural network. The deep neural network may include an input layer, L hidden layers, and an output layer, and the beamforming method may include: obtaining channel information h between a base station and K terminals and a transmit power limit value P of the base station, and inputting h and P into the input layer; and performing beamforming on signals to be transmitted to the K terminals using beamforming vectors derived using the output layer and at least one activation function, wherein the base station transmits the signals to the K terminals using M transmit antennas. Here, the output layer may be configured in a direct beamforming learning (DBL) scheme, a feature learning (FL) scheme, or a simplified feature learning (SFL) scheme.

Abstract: This application relates to a method of analyzing dynamic characteristics of a carbon composite material. This application also relates to a method of calculating sensitivity indices for structural stiffness and a viscous damping coefficient of a carbon composite material and a method of analyzing dynamic characteristics of a carbon composite material by using the same. Respective sensitivity indices for structural stiffness and a viscous damping coefficient according to a direction (angle) of carbon fiber for a carbon composite material are calculated. A change in the dynamic characteristics of the carbon composite material is evaluated through a proportional relationship between the sensitivity indices, thereby conducting a more accurate and efficient analysis.

Abstract: A method of manufacturing a composite material for thermal shields, and a composite material manufactured by the method are proposed. The method may include preparing a mixed powder including (i) a metal powder including a powder of aluminum or aluminum alloy and (ii) a polymer or ceramic powder. The method may also include sintering the mixed powder through pressureless sintering or spark plasma sintering to produce a composite material. According to the present disclosure, a powder of polymer, ceramic, and/or metal which have a relatively low level of thermal conductivity can be compounded with a metal material including aluminum through a sintering process of powder metallurgy, such as pressureless sintering or spark plasma sintering. Thus, a heterogeneous composite material with a low-level thermal conductivity (10 W/mk or less) can be obtained, and the composite material can be used as a material for various thermal shields.
