The invention discloses a large-scale video matrix exchange board and video processing board connecting structure which comprises a video matrix switching board, a video input-output processing board and a video channel connecting board. A first video channel connector is mounted at the upper end of one edge of the video channel connecting board and connected with the video matrix switching board, and two second video channel connectors are mounted in the middle of the other edge of the video channel connecting board and connected with the video input-output processing board. The connecting structure can realize a matrix function while having reasonable heat channels for heat radiation, input-output board cards are compatible with board cards for small-scale matrix cabinets, and the connecting structure does not need to be designed solely, thereby being reasonable in structure.

The invention provides a spliced screen system and an implementation method thereof. An inner-loop signal processing chip for converting a specified local audio / video signal received by a local video signal interface into a DP signal is arranged in each splicing unit. On one hand, the DP signal output by the inner-loop signal processing chip is converted into an LVDS signal, and on the other hand, the DP signal is output to a core processing chip of a next splicing unit which is connected with a DP output interface through the DP output interface, so that an internal matrix function of a spliced screen and an echo function of playing back a whole spliced screen display image onto a monitor of a remote control end in real time are realized. Additional separate configuration of a matrix module and a signal distributor module for the spliced screen is not required; convenience is brought to remote control of the spliced screen; the installation cost is lowered; and the defects of frame loss and delay of transmitted signals are overcome.

The present invention relates to a method for determining hydrocarbon production for a reservoir. The method comprisesdetermining a projector matrix based on a Jacobian matrix function of the gridded model, then splitting the Jacobian matrix into subsets of consecutive lines.For each subset of consecutive lines, creating a respective square matrix based on said subset.A determining eigenvectors and respective eigenvalues associated with the respective square matrix and then determining relevant eigenvectors having respective eigenvalues below a predetermined threshold.The projector is determined as a concatenation of the extended eigenvectors ordered according to multiple criteria: the respective order value of the subset; and the respective eigenvalue of the relevant eigenvector.

The invention comprises MCU, FPCA, keyboard, liquid crystal screen, memory, PC interface and eight communication node interfaces. The MCU makes system control, and converses the key assignment into matrix function to generate control signal, error -selecting signal and speed-selected signal. FGGA is used to implement the main function of simulator, and to make synchronous or asynchronous series connection with the eight channel node interface. The matrix control signal from MCU controls the data current direction to form a switch matrix, and to normalize the variable channel character into multi error code rates. The error-selected signal is used to control error code selection, load composition, and to output error flow analog characteristic. The communication speed selected signal is used to control and generate clock signal of communication speed and sequence control signal.
