Abstract: The effective method for Bayesian unconditional Cramer-Rao bound on condition that the unknown state-vector of a dynamical system is constant has proposed. The recurrence formula for calculating the Fisher information matrix is deduced. Our formula doesn’t follow from the well-known recurrence relations for the general case, where the state-vector varies, and has some advantages compared to them. The effectiveness of the proposed recursive method has been illustrated by applying to Вearing-only tracking.

Abstract: In order to solve optimal placement of bridge sensors based on the modal information, a multi-objective integer programming expected value model is established and the number of modal is considered as a stochastic variable in this paper, and here Fisher and MAC matrix are combined as the objective functions . Since DNA Genetic algorithm has the merits of plentiful coding, and decoding, conveying complex knowledge flexibly, these merits and the technique of stochastic simulation are also combined, which for estimating stochastic integer programming expected value models problem. And finally the feasibility of the algorithm is showed by XuGe Bridge as an example.
