  • Publication number: 20230286558
    Abstract: The invention relates to an operation diagram-based method for automatically changing a route to turn back in case of interruption. The method obtains an alternative turn-back point according to the position of a fault point and the information of a line turn-back station, calculates a corresponding turn-back plan of the alternative turn-back point according to an operation diagram of the current day, and finally automatically changes an online train route according to the new turn-back plan, so as to realize automatic turn-back of a train after route adjustment in case of interruption. Compared with the prior art, the method has the advantage of being able to keep the compatibility with an existing operation diagram while quickly changing a route in case of partial line interruption, so as to facilitate quick recovery of planned operation after a fault is removed.

  • Publication number: 20230206396
    Abstract: According to implementations of the subject matter described herein, a solution is proposed for super-resolution image reconstructing. According to the solution, an input image with first resolution is obtained. An invertible neural network is trained using the input image, wherein the invertible neural network is configured to generate an intermediate image with second resolution and first high-frequency information based on the input image, the second resolution being lower than the first resolution. Subsequently, an output image with third resolution is generated based on the input image and second high-frequency information by using an inverse network of the trained invertible neural network, the second high-frequency information conforming to a predetermined distribution, and the third resolution being higher than the first resolution. The solution can effectively process a low-resolution image obtained by an unknown downsampling method, thereby obtaining a high-quality and high-resolution image.

  • Patent number: 10096691
    Abstract: A method for forming a metal silicide. The method comprises: providing a substrate having a fin, a gate formed on the fin, and spacers formed on opposite sides of the gate; depositing a Ti metal layer; siliconizing the Ti metal layer; and removing unreacted Ti metal layer. As the Ti atoms have relatively stable characteristics, diffusion happens mostly to Si atoms while the Ti atoms rarely diffuse during the thermal annealing. As a result, current leakage can be prevented in a depletion region and thus leakage current of the substrate can be reduced.
