Triple-layer piezoelectric composite cantilevers possess good electromechanical conversion behavior with characteristics suitable for diverse applications, especially at low frequency. Thus, the use of such cantilevers has been extensively attempted in fabricating piezoelectric devices. This study reports on the accurate determination methods for the equivalent circuit parameters derived from the...
In this study we analyze mutual fund flow-performance relation by using a novel sample of Chinese mutual funds and focus on the impact of stock market conditions. we find that the flow-performance relation varies significantly with market conditions and the positive relation is more pronounced during bull markets. The asymmetric flow-performance relation under different market conditions is consistent...
This paper proposes a collaborative load forecasting method based on maximum entropy principle. Taking the expectation and second order central moment of forecasting results into account and using the maximum entropy principle, the load forecasting method receives the probability distribution function of the forecasted values and obtains the final high, middle and low forecasting scheme based on the...
The longitudinal motion equations were built by mathematical model of target drone movement. The longitudinal linearized equation was got by the lineairzation of longitudinal motion equations. The modality character was analysed by the solution. According to remolding motion, the effection on dynamic stability by flight speed, height and centroid position variation was researched and corresponding...
Unified Modeling Language (UML) provided effective means for aspect-oriented modeling, among which UML state machine was designed to model for the dynamic behavior of the system. UML state machine, however, failed to explicitly support the modeling of a crosscutting feature. The paper, based on UML extension methods, firstly set up state class in supported aspect from level of state machine meta-model,...
This paper introduces synergetic theory and proposes multi-path load forecasting automatically coordinated approach based on the maximum entropy principle. Taking the expectation and second order central moment of forecasted results into account and using the maximum entropy principle,this synergetic load forecasting method receives the probability distribution function of the forecasted values and...
Many types of shape descriptors have been proposed for 2D shape analysis, but most of them consist of component features that are not adapted to specific problems. This has two drawbacks. First, computation is wasted on the irrelevant components; second, the accuracy is impaired. This paper proposes an effective method that generates compact descriptors adapted to specific problems in hand, where...
