In this paper, an adaptive sliding mode control method is introduced to ensure robust synchronization of two different fractional-order chaotic systems with fully unknown parameters and external disturbances. For this purpose, a fractional integral sliding surface is defined and an adaptive sliding mode controller is designed. In this method, no knowledge of the bounds of parameters and perturbation is required in advance and the parameters are updated through an adaptive control process. The proposed scheme is global and theoretically rigorous. Two examples are given to illustrate effectiveness of the scheme, in which the synchronizations between fractional-order chaotic Chen system and fractional-order chaotic Rössler system, between fractional-order hyperchaotic Lorenz system and fractional-order hyperchaotic Chen system, respectively, are successfully achieved. Corresponding numerical simulations are also given to verify the analytical results. © 2012 Springer Science+Business Media Dordrecht.

This letter investigates the stabilization of three-dimensional fractional-order chaotic systems, and proposes a single state adaptive-feedback controller for fractional-order chaos control based on Lyapunov stability theory, fractional order differential inequality, and adaptive control theory. The present controller which only contains a single state variable is simple both in design and implementation. Simulation results for several fractional-order chaotic systems are provided to illustrate the effectiveness of the proposed scheme. © 2011 Springer Science+Business Media B.V.

Chaotic systems in practice are always influenced by some uncertainties and external disturbances. This paper investigates the problem of practical synchronization of fractional-order chaotic systems. Based on Lyapunov stability theory and a fractional-order differential inequality, a modified adaptive control scheme and adaptive laws of parameters are developed to robustly synchronize coupled fractional-order chaotic systems with unknown parameters and uncertain perturbations. This synchronization approach is simple, global and theoretically rigorous. Simulation results for two fractional-order chaotic systems are provided to illustrate the effectiveness of the proposed scheme. © Springer Science+Business Media B.V. 2011.

With the popularization of internet, cyber language is used more and more frequently. The network language has formed a unique system of computer language library. So studying of computer language has great significance to the development of the network language. Language library capacity can't be unlimited expansion. To enhance the computer language network function we must use correlation algorithm to simplify the computer language. In this paper, an improved method based on the network language new is proposed. We apply the neural network speech recognition model with multi hierarchy recognition technology to computer language, and put forward TEI model of computer network language identification. We use the VB program to call on the MATLAB software, successfully simplify the complex recognition process of the network language. At the same time, computer network language also has certain reference value for English language learning. It can help learners to avoid the negative effects of network language on the English language. © (2014) Trans Tech Publications, Switzerland.

Green evaluation index system of industrial building is to describe the evaluation content and scope of green industrial building, and reflect the green industrial building direction and the set of important measurable parameters. This paper introduces in the compiling process of Green Industrial Building Evaluation Standard, through the group experts analytic hierarchy process (AHP), the unreasonableness of index weights allocation in the result can be reduced. At the same time, this article discusses the rationality of the weight allocation result, through comparison and analysis on the evaluation index system of green industrial building, the British BREEAM industrial building and domestic green building. © 2014 IEEE.

A novel method for texture image classification was proposed by using dual-tree complex wavelets transform and support vector machines. The dual-tree complex wavelets transform was used to decompose texture image with four levels, feature vector was first used for training and later on for testing the support vector machine classifier. The experimental setup consists of twenty texture images from the Brodatz image database, results of experimental indicate that the presented method provide superior texture classification accuracy over other methods under the condition of limited training samples, and show the validity and the best generalization ability. © 2014 IEEE.

Mutual information (MI) is always used as the indicator of nonlinear correlation between the variables. The computation of MI can be finished only the continuous-value variables are discretized. In this paper, one new strategy of computing the MI between variables is proposed. The probability density estimation (PDE) is used to determine the density functions in our method. An approximate technology is applied to replace the computation of integral. Finally, MI based on PDE can be obtained. Through the artificially experimental simulations, the performance and rationality of our new method are demonstrated. The experimental results show that our method is feasible, effective and efficient. © 2011 IEEE.

Security of landscape engineering includes ecological security and personal safety. In this paper, two aspects of qualitative risk will be assessed in landscape engineering. In terms of ecological security, it has some major risks which includes department of community stability, soil quality which cannot meet the requirements of plant growth and plant pest disasters. In the process of construction, risks include fall from high-altitude, mechanical injury, electric shock and improper use of pesticides. In response to these security, we raise landscape engineering safety to measure and increase the diversity of plant communities, which emphasis on application of native plant species improve community stability. Plant quarantine, soil testing and other methods are employed to control plant pests and soil quality. Safety training and education and standardize operations are used to ensure the personal safety. © 2015 IEEE.
