    Modeling and simulation is recognized as a useful way to evaluate the effectiveness of command and control (C2) systems whereas the modeling of C2 systems is rather difficult. In order to model C2 systems, an entity relationship based method is raised. All levels and all kinds of command posts are abstracted into C2 entity model which is composed of capability model and behavior model. At the same... View full abstract»

    The initial stage of a compressible liquid jet impact onto an elastic plate is considered in the paper. A numerical model is built and the wave governing equation is approximated by a doubly asymptotic method. Theoretical solution at the impact instant is deduced through considering compressibility or not. Doubly approximation method is compared with the analytic solution by Korobkin and theoretic...

    Although the Empirical Mode Decomposition (EMD)-based decomposition and ensemble framework for time series forecasting has been widely used, the end effect of EMD has not been addressed adequately. This study proposed to incorporate Mirror Method (MM), capable of dealing with the problem of end effect, into a hybrid modeling framework with Ensemble Empirical Mode Decomposition (EEMD) and Support V...

    In this paper, four new forecasting models - univariate LS-SVM model and three hybrid models of ARIMA and LS-SVM models are introduced for wind power output forecasting. Historical data of 78 wind farms are used to compare and evaluate the performance of the best models. Empirical analysis indicates that the proposed univariate LS-SVM model and hybrid models can not significantly outperform linear... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (508 KB) | HTML iconHTML

    This study examines 356 tertiary education students' entrepreneurial career intentions (ECI) and its influencing factors. The results show that students' labor Market information (LMI) has a significant direct effect on ECI, and employability self-efficacy (ESE) has a significant effect on ECI through LMI. The influence pattern and empirical data of ESE and LMI on ECI has a good fit. View full abstract»

    This paper investigates the matrix nearness problem associated with the matrix equation AXB+XYD=E over reflexive (anti-reflexive) matrices. The problem is a 3-step optimization problem. Firstly, the matrices X and Y were defined as reflexive (anti-reflexive) matrices. Then the Frobenius norm of AXB+CYD-E was minimized. Lastly, the nearest matrices to the given matrices X* and Y* among the solution... View full abstract»

    In order to solve ill-conditioned problem more efficiently, a new method called Adaptive Regularization Method based on Normal Operator(ARMNO) is proposed. By analyzing weakness of the existing adaptive regularization method, we gave a new regularization strategy for ARMNO. Property shows that ARMNO has stronger regularity than Tikhonov regularization method. For illustration, a measured GPS examp... View full abstract»

    De novo peptide sequencing is an important method for peptide sequencing and protein identification. It can be transformed into a special case of paths avoiding forbidden pairs problem (PAFP). General PAFP is NP-complete. The definition of PAFP is the following: Given a directed acyclic graph G = (V, E), two distinguished vertices source s, sink t ∈ V , a set of forbidden pairs F ⊂ V...

    We conduct statistical inference on data collected from extreme-value distribution under a progressive Type-II censoring scheme in this paper. By converting the extreme-value model into a Wei bull model, the computation of the maximum likelihood estimator (MLE) for model parameters can be greatly simplified. The bias, variance and covariance of the MLEs under various censoring schemes are investig... View full abstract»
