Abstract: A computer-implemented model is trained or otherwise configured for real-time production control. The model incorporates a plurality of classes of residence time control and optimizes produce performance by managing an associated machine's behavior according to real-time system states. The model can formulate a Markov decision process and feature-extraction method and feature-based approximation architecture to reduce state space of the model. Simulation is employed in training to estimate parameters of feature-based approximate architecture to obtain a lookahead function of the Markov decision process.

Abstract: A deformation-driven solid-phase extrusion device and a one-step alloy bar preparation method by using the same are provided. The device includes a stir tool, an extrusion container and an ejector rod. The stir tool has an integral structure composed of an upper mounting part and a lower working part and having a hollow channel. The lower working part is disposed in a groove of the extrusion container, and the ejector rod is disposed in the hollow channel of the stir tool. The method includes adding alloy powder to the extrusion container, enabling the stir tool to exert a pressure and revolve at a high speed to cause large plastic deformation of the powder and generate heat by friction and deform among powder and the friction working surface of the working part, sintering the alloy powder and extruding the same through the hollow channel of the stir tool.

Abstract: A method and apparatus for reducing interference and a mobile terminal using the method and apparatus. The method includes: selecting a display mode of a pixel, for a frequency falling into a receiving band range of radio communication, according to a corresponding relation between the pixel to be displayed and a strength value of interference induced in the frequency. The present invention may not only further reduce interference brought by the MIPI high-speed data transmission to radio communication receiver, but also have effect on those bands lower than 1 GHZ, lower the requirements on hardware and hence lower hardware cost, and occupy no design space.
