Method for identifying file type and apparatus for identifying file type
A method for identifying a file type and an apparatus for identifying a file type, so as to solve a problem in the prior art that a file type cannot be effectively identified when a sender tampers with a file being transmitted. The method includes: acquiring, from a transmitted data packet, a file header of a file to be identified, and determining whether a magic number can be obtained from the file header; if the magic number can be obtained, searching for the file type that corresponds to the magic number; determining whether data of the file to be identified complies with a data structure feature of the file type; if yes, determining that a file type of the file to be identified is the file type that corresponds to the magic number; and if not, determining that a file type of the file is an abnormal type..

Method for controlling gait of robot
A method includes: forming an imaginary wall at a position spaced apart and outward from feet of the robot when the robot is in a double-leg-support state; kinetically calculating a variation in a distance between a body of the robot and the imaginary wall and a variation in a speed of the body of the robot relative to the imaginary wall using an angle of a joint and lengths of links of the robot; applying the variation in the distance and the variation in the speed to an imaginary spring-damper model formed between the body of the robot and the imaginary wall, and calculating an imaginary reaction force required by the body of the robot; and converting the calculated reaction force into a drive torque required by the body of the robot using a jacobian transposed matrix.. .
