Nettetsource point in terms of influence function of a physical problem. The RBF (15) reflects to some extent physical background of nonlinear terms. In other words, the present scheme is an intrinsically nonlinear numerical discretization technique. The broad definition of the kernel RBF involves the use of nonsingular high-order NettetIn estimation theory, the extended Kalman filter ( EKF) is the nonlinear version of the Kalman filter which linearizes about an estimate of the current mean and covariance. In the case of well defined transition models, the EKF has been considered [1] the de facto standard in the theory of nonlinear state estimation, navigation systems and GPS.
NettetQuestion Find all the critical points of the non-linear system dx dt = x y x 2 + xy dy dt = x 2 y and identify their types. The sketch a possible phase-portrait for the system. Solution To find the critical points we need to find all solutions to the simulatanous equations x y x2 + xy = 0 x2 y = 0 In general there is no guaranteed method for doing this, so be creative! http://www.diva-portal.org/smash/get/diva2:21266/FULLTEXT01.pdf
