From perspective of magnetite iron core inductive sensor, iron grade’s quick detecting method for magnetite is given. Sensing mechanism of the sensor is analyzed. Magnetic field model is built, and numerical analytic expressions are given among magnetic induction intensity, inductance value and induced electromotive force of the iron core inductive sensor. By using the finite element energy method, numerical model of inductance of cylindrical solenoid iron core winding is solved. Boundary conditions are set according to geometric characteristics of the winding, and adopting ANSYS finite element analysis software, simulation models for windings of the iron grade sensor are built;influence regulations of changing of self-inductance coefficients of the winding on output inductance value of the sensor are gotten, furthermore, optimal combination of self-inductance coefficients of structure of the magnetite core inductance sensor is determined. The research lays foundation for ultimate realization of real-time monitoring of iron grade for the magnetite. © 2015 Taylor & Francis Group, London.

In the resource allocation process of multi-user OFDM system, in order to realize the purpose of maximizing the total transmission rate under constant power, a new subcarrier allocation algorithm has been proposed in this paper, which is to introduce cultural evolution method into the original artificial fish swarm algorithm. Because the population space in cultural algorithm framework has the advantage of guiding search process, the new algorithm can effectively overcome the defect of falling into local extreme which generally exists in the fish swarm algorithm in the resource allocation. At the same time, the proposed new algorithm also can make it easy to quantify the optimized goals and variable values. Simulation results show that the proposed artificial fish swarm algorithm with cultural evolution (CE-AFS) has been greatly improved the global search ability and convergence speed compared with the AFS algorithm and Shen algorithm. © 2015 SERSC.
