To maintain the durability of data collection and improve charging efficiency for a mobile wireless charging vehicle (WCV) in Wireless Rechargeable Sensor Networks (WRSNs), a grid-based joint routing and energy replenish scheme (GRER) is proposed in this paper, aiming to achieve energy balance and maximize recharging benefit. Based on WCV charging service, network is firstly divided into several virtual grids with the help of minimum coverage area idea and a simple concurrent multi-hop chain-based routing protocol is proposed for forming data transmission links. Then, WCV visits and charges nodes using an angle expansion-based breadth-first strategy (AEBF) within the limited battery capacity. Simulation results demonstrate that GRER outperforms FCFS, NJNP, LADP and RCSS schemes in regards to network lifetime, energy balance and charging efficiency.

In this paper, we present a nonmonotone smoothing Newton algorithm for solving the circular cone programming(CCP) problem in which a linear function is minimized or maximized over the intersection of an affine space with the circular cone. Based on the relationship between the circular cone and the second-order cone(SOC), we reformulate the CCP problem as the second-order cone problem(SOCP). By extending the nonmonotone line search for unconstrained optimization to the CCP, a nonmonotone smoothing Newton method is proposed for solving the CCP. Under suitable assumptions, the proposed algorithm is shown to be globally and locally quadratically convergent. Some preliminary numerical results indicate the effectiveness of the proposed algorithm for solving the CCP.

Based on the method of averaging, in this paper we investigate the continuation of harmonic motions for a weakly forced autoparametric vibrating system which models the dynamics of a forced pendulum positioned on a vertically excited mass. The result shows that when the very weakly force is imposed on the pendulum, a state of dynamic balance (a harmonic motion) is preserving.

In this paper, we present an improved method based on Zippel's algorithm for multivariate polynomial interpolation, and a testing point technique is proposed to verify the recovered polynomial. Compared with Zippel's algorithm, the new method not only returns an exact target polynomial but takes less computation time as well. The experiments show the effectiveness of the improved method.
