This paper proposes a novel confusion and diffusion method for image encryption. One innovation is to confuse the pixels by transforming the nucleotide into its base pair for random times, the other is to generate the new keys according to the plain image and the common keys, which can make the initial conditions of the chaotic maps change automatically in every encryption process. For any size of the original grayscale image, after being permuted the rows and columns respectively by the arrays generated by piecewise linear chaotic map (PWLCM), each pixel of the original image is encoded into four nucleotides by the deoxyribonucleic acid (DNA) coding, then each nucleotide is transformed into its base pair for random time(s) using the complementary rule, the times is generated by Chebyshev maps. Experiment results and security analysis show that the scheme can not only achieve good encryption result, but also the key space is large enough to resist against common attacks. © 2012 Elsevier B.V.

Micro Grid has been considered as a challenge among power utilities as well as communities in many countries around the world. Many studies have been done to date on Micro Grid technology and operations, but fewer studies such as economic and environmental impact assessment still needs to challenge. This paper intends to assess economic and environmental impacts of Micro Grid which forming by renewable energy micro-wind power plant (MWPP), micro-hydro power plant (MHPP) and solar power plant (SPP) and planned to install in a rural area. Yardstick of economic merit such as Net Present Value (NPV), Benefit-Cost Ratio (BCR) and Payback Period (PBP) are mainly presented in this study with environmental impact assessment. Source

Based on the analysis and introduction of blind source separation, it analyzes the signal sorting of the maximum kurtosis natural logarithm, compares the signal model forms of the narrowband blind beam forming and instantaneous hybrid model of blind source separation and those of the broadband blind beam forming and convolutive hybrid model of blind source separation, and obtains the conclusion that the broadband blind beamforming and convolutive hybrid model of blind source separation can adopt the same signal model. It finally proposes a model for the broadband smart antenna of blind adaptive beamforming device. © 2011 IEEE. Source

This paper proposes a color image encryption scheme based on Choquet fuzzy integral (CFI) and hyper chaotic system. The major core of the encryption algorithm is a pseudo-random number generator based on the CFI. Before encrypting the color image, the piecewise linear chaotic map (PWLCM) is used to generate the 128-bit secret keys, and the Lorenz system is iterated for limited times to generate the initial parameters of the CFI. The outputs of the CFI are used to confuse and diffuse the three components of the pixel, respectively. Experiment results and security analysis show that the scheme not only can achieve good encryption result and large key space, but also can resist against common attacks, so the scheme is reliable to be adopted for network security and secure communications. © 2012 Elsevier GmbH.

In this paper, we consider a class of nonautonomoua N-species Lotka-Volterra competitive systems with impulsive effects. Some new criteria on the permanence and global attractivity are established by developing the methods given in [Z. Teng and Z. Li, Permanence and asymptotic behavior of the N-species nonautonomous Lotka-Volterra competitive systems, Comput. Math. Appl. 39 (2000) 107-116; S. Ahmad and I.M. Stamovab, Asymptotic stability of an N-dimensional impulsive competitive system, Nonlinear Anal. RWA 8 (2007) 654-663]. © 2009 Elsevier Ltd. All rights reserved. Source
