The rapid development of radio frequency identification (RFID) technology creates the challenge of optimal deployment of an RFID network. The RFID network planning (RNP) problem involves many constraints and objectives and has been proven to be NP-hard. The use of evolutionary computation (EC) and swarm intelligence (SI) for solving RNP has gained(More)
The performance of differential evolution (DE) largely depends on its mutation strategy and control parameters. In this paper, we propose an adaptive DE (ADE) algorithm with a new mutation strategy DE/lbest/1 and a two-level adaptive parameter control scheme. The DE/lbest/1 strategy is a variant of the greedy DE/best/1 strategy. However, the population is(More)

The optimal selection of parameters for time-delay embedding is crucial to the analysis and the forecasting of chaotic time series. Although various parameter selection techniques have been developed for conventional uniform embedding methods, the study of parameter selection for nonuniform embedding is progressed at a slow pace. In nonuniform embedding,(More)
Fault diagnosis has played an important role in the identification of fault mechanisms and the subsequent successful isolation of faults in electronic circuits. In this paper, we propose a novel procedure for fault diagnosis in analog circuits. We first generate a set of fault patterns from fault simulation, and our main task is to develop a practical(More)
Many theoretical studies prove the SAW gyroscopic effect and presume that the rotation sensitivity character is of interest for the development of rotation sensors, but these studies are insufficient experimental proofs. The effect of Coriolis force on SAW is analyzed and testified by experiments in this paper. The Christoffel's equation including Coriolis(More)
The signal of the wireless sensor network in Grounding grid, owing to energy loss, network congestion, path constraints and other factors, is easy to delay even partially losing. In order to ensure that the signal can be transmitted effectively in grounding grids for the substation, this paper presents a method based on traffic model of back-off balanced(More)
An approach to analog fault diagnosis for circuits with tolerance is presented based on data fusion. The proposed strategy consists of preliminary diagnosis and decision fusion. Preliminary diagnosis is performed separately by using one kind of fault signatures from multiform circuit responses. The preliminary diagnosis results are aggregated using an(More)
