    摘要: A method and apparatus are provided for dynamically controlling a high speed wireless communication system capable of transmitting a message via a communication channel, to minimize the transmission power necessary for a single job and thereby increase system capacity. The communication channel is characterized by performance characteristics curves and physical channel characteristics curves. Channel conditions are sampled to model the performance characteristic curvers. Upon determining a minimum throughput to meet a Quality of Service requirement for user application, a first set of data pairs that correspond to the minimum throughput are determined from the performance characteristics curves. That first set of data pairs is in mapped to the physical channel characteristic curver and the data pair corresponding to minimum transmission power is then selected.

    摘要: In a collaborative video processing method and system, a high resolution video input is optionally downscaled to a low resolution video using a down-sampling filter, followed by an end-to-end video coding system to encode the low resolution video for streaming over the Internet. The original high resolution is obtained at the client end by upscaling the low resolution video using a deep learning based high resolution scaling model, which can be trained in a pre-defined progressive order with low resolution videos having different compression parameters and downscaling factors.

    摘要: It is a numerical method for solving an inverse problem about the shape design of aerodynamic body in inviscid subsonic flows. This method transfers the original Euler equations into the stream-function plane, where it solves the Riemann problem across the streamline presenting the solid-wall and obtains the geometry of the solid-wall concurrently.

    摘要: The present invention relates a numerical method to simulate the incompressible wing-tip vortex flows. This method is called Vorticity-Refinement, which refines the added vorticity as two different forms of force multiplied by two different factors to counteract the numerical diffusions in the numerical solutions by utilizing the high-order spatial discretization and improving the stability and convergence of the governing equations for incompressible flows.

    摘要: A Karman vortex street generator including a shell (1), permanent magnets (3, 6), a vortex generating body (4), and a metal winding (5). Both ends of the shell (1) are respectively provided with an inlet end (2) and an outlet end (7). The permanent magnets (3, 6) are respectively located on two corresponding surfaces inside the shell (1), and the N pole of the permanent magnet on one surface corresponds to the S pole of the permanent magnet on the other surface so as to form a magnet field in the shell (1). The vortex generating body (4) is provided in the vertical center position near the inlet end (2) in the shell (1) so as to generate a Karman vortex when a fluid flows. The metal winding (5) located in the magnet field is able to regularly cut magnetic lines of force under the action of the Karman vortex and makes magnetic flux passing through the metal winding (5) change so as to generate an induction current.
