  • Publication number: 20230384769
    Abstract: The present application discloses an establishing method for establishing a dyeing model, a dyeing method, a device, and a storage medium which are applied to the dyeing technology field. The establishing method includes: obtaining historical data of dyeing a workpiece, the historical data includes historical dyeing time of the workpiece and historical color value of the workpiece after dyeing; and obtaining the dyeing model by training an initial model based on the historical data. The dyeing model is established using the historical data, and can establish a relationship between the dyeing time and the color value of the workpiece after dyeing. Based on the dyeing model, the dyeing time required for the workpiece can be determined according to a color value of the workpiece after dyeing. A precise dyeing process can be realized by determining the dyeing time using the dyeing model instead of determining the dyeing time manually.

  • Publication number: 20220251692
    Abstract: An alloy cast strip preparation method includes a melting process and a casting cooling process. The melting process includes controlling a power of an induction melting furnace to perform a cyclic heat treatment to completely melt an alloy raw material before a surface temperature of a melt obtained by melting the alloy raw material is raised to 1300° C., and, after the alloy raw material is melted, adjusting the power of the induction melting furnace to stabilize the surface temperature of the melt at a temperature in a range from 1400° C. to 1500° C. The casting cooling process includes performing casting cooling on the melt arranged on a surface of a rotary cooling roll to obtain an alloy cast strip while controlling a surface linear velocity of the rotary cooling roll to be from 1.5 m/s to 2.25 m/s.

  • Patent number: 10025198
    Abstract: The present invention generally relates to simulating a lithographic process, and more particularly to methods for smart selection and smart weighting when selecting parameters and/or kernels used in aerial image computation. According to one aspect, advantages in simulation throughput and/or accuracy can be achieved by selecting TCC kernels more intelligently, allowing highly accurate aerial images to be simulated using a relatively fewer number of TCC kernels than in the state of the art. In other words, the present invention allows for aerial images to be simulated with the same or better accuracy using much less simulation throughput than required in the prior art, all else being equal.

  • Patent number: 9591678
    Abstract: The present invention relates to a call processing method and an access network element in a mobile communications system. In a signaling exchange process for setting up a call leg, a call leg identifier that identifies a logical resource allocated by an access network element to the call leg is carried, thereby reducing signaling exchange caused by setup or release of a service link between access network elements in the prior art, saving signaling overhead in a call process, and enhancing call access capabilities of a mobile communications system effectively. In addition, after the service link between the access network elements is set up, service packets can be forwarded between the access network elements in a self-addressing manner.

  • Publication number: 20090193436
    Abstract: An alarm display system of a cluster storage system and a method thereof are described. A reasonable single abnormal event processing manner is adopted to classify the alarm priority through abnormal events detected by different nodes sharing a common device in the cluster storage system, and analyze load of each node. That is, nodes with lower loads are analyzed to obtain all the abnormal events of the common device and the node most affected by the abnormal events in the cluster storage system. Afterward, the analysis result is transmitted to each node, and each node then informs a subscriber with an alarm prompt, so as to reasonably and correctly alarm the subscriber with abnormal events of the common device and impacts thereof on the nodes.
