MAC layer design is critical for energy efficiency in wireless sensor networks. We present an approach to reduce the time spending on data moving. In our approach, a MAC layer needs to stripe off the network layer header and store a data frame received until receiving the next hop address from the network layer where a route look-up is executed. The amount(More)
A non-coherent detection algorithm was proposed for orthogonal space-time coded multi-level continuous phase modulation (OST-MCPM) transmission systems of two transmit antennas, using a non-coherent maximum likelihood (ML) approach with different lengths of watch window. The noncoherent detection algorithm is suitable for any number of receive antennas and(More)
In this paper, the output feedback control problem for a genetic hypersonic vehicle is considered under the restriction that only the vehicle’s velocity and altitude are measurable. High gain observers (HGO) are utilized to provide estimation signals for unmeasurable derivatives of the vehicle’s velocity and altitude. Neural network based feedforward(More)
In this paper, a method is proposed to compute all the strict minimal siphons (SMS) in an SPR based on resource circuits. The concepts of A-resource subsets, B-resource subsets, and elementary B-resource subsets are proposed, which play an important role in finding SMS. Moreover, it is proved in this paper that not all the resource circuits can generate SMS(More)
Using a sample of 1,163 adolescents from four middle schools in China, this study explores the intervening process of how adolescent maltreatment is related to delinquency within the framework of general strain theory (GST) by comparing two models. The first model is Agnew's integrated model of GST, which examines the mediating effects of social control,(More)
In this article, an algorithm is proposed to design liveness-enforcing supervisors for systems of simple sequential processes with resources (S<sup>3</sup>PR) based on complementary places. Firstly, a mixed integer programming (MIP) based deadlock detection method is used to find unmarked strict minimal siphons from an infinite-capacity net. Next, the(More)
In this paper, the output feedback control problem for a genetic hypersonic vehicle is considered under the restriction that only the vehicle's velocity and altitude are measurable. High gain observers (HGO) are utilized to provide estimation signals for unmeasurable derivatives of the vehicle's velocity and altitude. A comprehensive stability analysis of(More)
With the improvement of quality of software, software reliability becomes more and more important. Until now, there have been many software reliability models, but the few is suitable for all software projects. Moreover, in the application, it is hard to apply them effectively, because of the operational and other factors, this paper full analyzes the(More)
