In this paper, without assuming symmetry, we proved linearly coupled complex networks could achieve cluster synchronization under pinning control. Sufficient conditions guaranteeing cluster synchronization for any initial values are derived by using feedback schemes. Moreover, we propose an adaptive feedback algorithms to adjust the coupling strength. Several numerical examples are given to illustrate...
In this paper, the exponentially synchronization is investigated for stochastic complex networks with both switching topology and time-varying delays via pinning control. The model of complex network is quite general since many factors such as noise perturbations, switching topology and internal and outer time-varying delays are considered. By employing the Lyapunov-Krasovskii functional, the It¡§o...
With 112 listed companies from A-share market in Chinese securities markets as research sample, authors selected 56 newly ST companies among 2007 and 2008 as distressed enterprises group, and other 56 non-ST companies as comparison group. 13 financial indicators of these companies at three year before being ST were screened out, and the factor analysis and logistic regression were conducted. It found...
In this paper we report a 850nm oxide VCSEL operating at 20 Gbit/s (PRBS31) with a 5 dB Extinction Ratio, based on a volume manufacturing platform with MOCVD grown GaAs/AlGaAs epi-material. We present detailed time and frequency domain VCSEL characterization results, and a finite element simulation showing good agreement with experimental data.
In this paper we report 850nm oxide VCSEL operating at up to 25 Gb/s (PRBS31) with 5dB ER, based on a high volume manufacturing platform with MOCVD grown GaAs/AlGaAs epi-material. We will also discuss VCSEL characterization results relevant for optical transceiver applications beyond 10Gb/s.
In this paper, we present implementation of an infinite impulse response (IIR) adaptive filter with particle swarm optimization (PSO) on field programmable gate array (FPGA). Particle swarm optimization performs a structured randomized search of an unknown parameter space by manipulating a population of parameter estimates to converge on a suitable solution. And this technique is independent of the...
This paper proposes an innovative prioritized restoration algorithm which enables carefully scheduled preemption (RAPPE). Firstly, it makes dedicate differentiation among network resources based on their roles in holding up services (working or backup) as well as the service levels they are carrying; secondly, it enables both higher level service preempting resources of lower and lower level service...
