    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: An electronic label system is provided which includes a data source having information to be displayed by an electronic label. An optical source such as an LED array broadcasts optical signals modulated with the data source data to plural electronic labels. Each electronic label has an optical receiver which receives the modulated optical signals and also receives unmodulated optical signals to supply power to an energy storage device. A mode switch switches the optical receiver between a signal reception mode and an energy storage device power-supplying mode. One or more bistable displays display the data received from the modulated optical signals. Through the use of bistable displays, the power consumption of the electronic label is greatly reduced while use of a single receiving element for receiving both the signal light and power storage light reduces the number of components needed to assemble the electronic label, thus reducing cost.
