Abstract: A device and method with batch normalization are provided. An accelerator includes: core modules, each core module including a respective plurality of cores configured to perform a first convolution operation using feature map data and a weight; local reduction operation modules adjacent to the respective core modules, each including a respective plurality of local reduction operators configured to perform a first local operation that obtains first local statistical values of the corresponding core module; a global reduction operation module configured to perform a first global operation that generates first global statistical values of the core module based on the first local statistical values of the core modules; and a normalization operation module configured to perform a first normalization operation on the feature map data based on the first global statistical values.

Abstract: A device including processors configured to execute instructions and memories storing the instructions, which when executed by the processors configure the processors to perform an operation for training a transformer model having a plurality of encoders and a plurality of decoders by configuring the processors to identify the batches of training data into a plurality of micro-batches, select layer pairs for the plurality of micro-batches, assemble a processing order of the layer pairs, determining resource information to be allocated to the layer pairs, and allocate resources to the layer pairs based on the determined resource information to be allocated to the layer pairs, dependent con the processing order of the layer pairs.

Abstract: Disclosed is a method and apparatus for adjusting heating value of natural gas, wherein components having high heating value are separated from natural gas consisting of various hydrocarbon components to reduce heating value of natural gas supplied to the markets. The method includes heating liquefied natural gas (LNG), separating the LNG heated and partially gasified into a gaseous component having low heating value and a liquid component having high heating value.

Abstract: Disclosed is an electric wax chisel. A main body having a shape of hollow cylinder includes a tank provided inside the hollow cylinder. The tank contains wax. A chisel tip having a hole is installed at one end of the main body. A heating member is disposed in the outer face of the tank. A control box is electrically connected with the main body by an electric wire. The main body comprises a first chamber and a second chamber. The first chamber has an exit hole at one end, in which the chisel tip is mounted, and an inlet hole at the other end. The second chamber has a discharging hole correspond to the inlet hole, and a tank to contain a wax. A terminal for supplying an electric power is disposed in the second chamber. A cap for sealing the second chamber is provided. The cap has a space depressed inwardly along the tube axis. Therefore, the electric wax chisel is improved so as to use easily and conveniently.
