Abstract: Provided is an impedance spectroscopy analytical method for concrete using machine learning. The method comprises identifying electrical flow through moisture and a conductive ion present in concrete using a node that measures electricity based on electrochemical impedance spectroscopy (EIS); generating a theoretical equivalent circuit model comprising a conductive path reflecting the electrical flow: normalizing an equivalent circuit reflecting a concrete microstructure based on an impedance experiment using the theoretical equivalent circuit model; and generating a predictive model for estimating a water and cement ratio from a parameter value of the equivalent circuit through machine learning. Accordingly, the accuracy and reliability of estimating the microstructure and mixing ratio of the cement-based material can be increased.

Abstract: Provided is a dynamic security policy enforcement system for a container system. The dynamic security policy enforcement system comprises a policy management unit for generating and managing a security policy for a container based on a structured format including a set of rules of a predetermined condition; a policy enforcement unit for checking the set of rules when the container requests a system call, changing the security policy of the structured format into a code in a preset format, and transferring the policy changed into the code to a kernel space; and a policy operation decision unit for enforcing the policy received from the policy enforcement unit in the kernel space based on a policy enforcement program that hooks the system call and generating a return value for performing a predetermined operation. Due to this, a policy can be applied to containers in all states including an initialization state and a running state at any time, and there is no need to restart the system or container to apply the policy.

Abstract: Provided are a patch GAN-based depth completion method and apparatus in an autonomous vehicle. The patch-GAN-based depth completion apparatus according to the present invention comprises a processor; and a memory connected to the processor, wherein the memory stores program instructions executable by the processor for performing operations in a generating unit of a generative adversarial neural network comprising a first branch and a second branch based on an encoder-decoder comprising receiving an RGB image and a sparse image through a camera and LiDAR, generating a dense first depth map by processing color information of the RGB image through the first branch, generating a dense second depth map by up-sampling the sparse image through the second branch, generating a dense final depth map by fusing the first depth map and the second depth map, and determining, by a discriminating unit of the generative adversarial neural network, whether the final depth map is fake or real by dividing the final depth map and depth measurement data into a plurality of patches.
