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.

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.

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.
