Abstract: The application provides a task scheduling simulation system, comprising a data preprocessing subsystem and a task scheduling subsystem. The data preprocessing subsystem filters the input cloud computing log information for abnormal data and extracts the running time of each task. The task scheduling subsystem enqueues or dequeues tasks from the batch task and real-time task running queues of each node, and keeps the tasks currently running in the cluster consistent with the actual production environment, and updates the number of CPU cores and the used and available memory capacity of each node according to resource requirement of each task. The mixed scheduling simulation of batch tasks and online tasks can be realized, and the resource simulation of the heterogeneous CPU core number and memory capacity of the cluster nodes can be simulated.

Abstract: Disclosed are a texture synthesis method and a device using the same. The texture synthesis method adopts a source labeled diagram and a target labeled diagram in combination to guide the texture synthesis process, so that the texture synthesis is in a controlled state, thus effectively improving the accuracy and efficiency of the computer in processing complex texture information such as textures composed of multiple materials or textures involving non-uniform gradients. Meanwhile, determination of the accuracy of the texture features of the labeled diagram is introduced to the process of producing the labeled diagram, and the labeled diagram with low accuracy is re-abstracted and -segmented so that the classification of the texture features would be more accurate. This interactive iterative method improves the accuracy of the labeled diagram generation process. The device using this method also provides the same technical effects.

Abstract: A three-degree-of-freedom parallel mechanism with curved sliding pairs includes a fixed platform, a moving platform, and three curved branches disposed between the fixed platform and the moving platform. Each of the curved branches includes a first curved link and a second curved link that share a common arc center. One end of the first curved link is connected to fixed platform by a rotational pair. One end of the second curved link is disposed in a cavity at another end of the first curved link. The second curved link is operative to perform a reciprocating motion along a tangent of an arc of the first curved link. Another end of the second curved link is connected to the moving platform by a ball joint. The axes of the three rotational pairs of the three curved branches coincide with each other and are perpendicular to the fixed platform. In the three-degree-of-freedom parallel mechanism with curved sliding pairs, the moving platform of the parallel mechanism is rotatable around the X-axis, Y-axis, and Z-axis of a three-dimensional coordinate system taking the arc center of the three curved branches as the origin, where the rotation of the moving platform about the Z axis is decoupled from the rotation in the other two orientations.
