Computational Sciences and Optimization are two important disciplines in modern sciences with many applications ranging from applied sciences, engineering, management, finance, and economics, to arts, humanities, and social sciences. Currently some new challenges arise in the modeling of complex systems, sophisticated algorithms, advanced scientific and engineering computing and associated problem-solving...
In this paper, a set of generalized strictly diagonally dominant matrix are discussed. We give some sufficient conditions for generalized strictly diagonally dominant matrices based on the theorem of ¦Á-diagonally dominant matrix. Finally, two numerical examples for the effectiveness of the proposed theorem are presented.
In this paper, we have proposed a constructive methodology for temporal data learning supported by results and prescriptions related to the embedding theorem, and using the singular spectrum analysis both in order to reduce the effects of the possible discontinuity of the signal and to implement an efficient ensemble method. In this paper we present new results concerning the application of this approach...
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...
In order to further improve the attitude control accuracy of the spacecraft and analysis the star identification algorithm, an effective simulation method of star atlas is proposed. This approach utilizes the same field of view in different latitude to calculate the exact position of observed stars in the charge-coupled device (CCD) image plane. Based on the magnitude, right ascension and declination...
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 theoretical...
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 Vector...
In this paper, four new forecasting models ¨C 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...
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.
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 solutions...
In this paper, we investigate the existence of positive definite solutions for the matrix equation X+A*X-1A=I. A new inversion free variant of the basic fixed point iteration method for obtaining the maximal positive definite solution is established. Moreover, some necessary conditions and sufficient conditions for the existence of positive definite solutions of the matrix equation are obtained. In...
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 example...
