Wireless sensor networks are characterized by multihop network. Some nodes in network are required to forward a disproportionately high amount of traffic and die early, leaving the unmonitored areas in network and leading to the problem of energy hole. This paper investigates a variety of strategies to avoid the energy hole, such as communication power control, data aggregation, nonuniform energy distribution, mobile node auxiliary and clustering. The analysis and comparison of different strategies are given and the advantages and disadvantage of them are discussed in this paper.
In this paper, a heuristic algorithm which embedded in the Lagrangian relaxation algorithm is proposed to obtain the near optimal solution to minimize the total weighted complete time in the Hybrid flow shop problem (...

controller switching algorithms used for Unfalsified Adaptive control are investigated. The concept of interfalsification, a generalization of the existing ε-hysteresis algorithm, is defined; the concept of self-falsification is introduced; and the two concepts are compared. New controller switching algorithms are designed based on the idea of self-falsification. These algorithms relax the assumption that the cost function be monotonically nondecreasing in time, and are thus more flexible than the existing inter-falsification algorithm. Simulations illustrate that the self-falsification algorithms can be used with non-monotone cost functions.
Finding the ground states of Sherrington-Kirkpatrick (SK) spin glass, the mean-filed spin glass model with strongly connected variables, is well known as a typical NP-hard problem. This paper presents a modified extre...

The paper considers the problem of tracking control of a class of nonlinear systems with unknown periodic time-varying parameters via dynamic output feedback. Both matched disturbances and unmatched disturbances are considered. A new method for asymptotic rejection of multiple general periodic disturbances is presented. The method can guarantee that all signals in the closed loop system are bounded and the tracking error approaches zero.
