Abstract: Disclosed herein are a neural network model deployment method and apparatus for providing a deep learning service. The neural network model deployment method may include providing a specification wizard to a user, searching for and training a neural network based on a user requirement specification that is input through the specification wizard, generating a neural network template code based on the user requirement specification and the trained neural network, converting the trained neural network into a deployment neural network that is usable in a target device based on the user requirement specification, and deploying the deployment neural network to the target device.

Abstract: A self-healing alloy contains 5 to 11% by weight of molybdenum (Mo), iron (Fe) as a remainder, and unavoidable impurities. A method for manufacturing the self-healing alloy includes heat treating the alloy or preparing an alloy raw material powder and sintering, homogenizing, and cooling the alloy raw material powder.

Abstract: A wireless local area network power saving method and an access point are provided. The access point implements a sleep mode regardless of whether the access point connects to a station. Furthermore, the access point sets different access point wake-up time period depending on the situation whether the access point connects to the base station or not such that power saving effect is enhanced.
