This paper studies boundedness of solutions of bidimensional switched affine linear systems. Every subsystem of the systems has a single stable/ unstable focus/ center and all the equilibria pairwise differ. By using the multiple polar coordinate systems method, this paper proposes a condition of boundedness of solutions of such switched systems under periodic/ quasi-periodic switching paths. The condition is also shown a sufficient condition of global asymptotic region stability of such switched systems with respect to a region containing all multiple equilibria. A global asymptotic region-stabilizing control, a periodic/ quasi-periodic switching path, and a corresponding algorithm are all designed for such switched control systems. An illustrative example demonstrates the effectiveness and practicality of our new results. © 2017 Chinese Automatic Control Society and John Wiley & Sons Australia, Ltd.

High-order rogue wave solutions of the Benjamin–Ono equation and the nonlocal nonlinear Schrödinger equation are derived by employing the bilinear method, which are expressed by simple polynomials. Typical dynamics of these high-order rogue waves are studied by analytical and graphical ways. For the Benjamin–Ono equation, there are two types of rogue waves, namely, bright rogue waves and dark rogue waves. In particular, the fundamental rogue wave pattern is different from the usual fundamental rogue wave patterns in other soliton equations. For the nonlocal nonlinear Schrödinger equation, the exact explicit rogue wave solutions up to the second order are presented. Typical rogue wave patterns such as Peregrine-type, triple and fundamental rogue waves are put forward. These high-order rogue wave patterns have not been shown before in the nonlocal Schrödinger equation. © 2017 World Scientific Publishing Company

In fed-batch fermentation of glycerol bio-dissimilation to 1,3-propanediol (1,3-PD) by Klebsiella pneumoniae, glycerol and alkali are fed into the reactor to provide nutrient and maintain a suitable environment for cells growth. Taking the feeding process as a time-continuous process, we present a nonlinear multistage dynamical system to formulate the fed-batch fermentation. In view of the big errors between experimental data and computational values, a parameter identification model is established. Finally, an improved Nelder-Mead simplex search method is developed to seek the unknown parameters in the model. Numerical simulations show that the multistage dynamical system can describe the fed-batch process better, compared with the previous results. © 2010 IMACS.

Heap sort algorithm is studied thoroughly, a new incomplete heap sort algorithm is designed, and then a novel image median filtering algorithm based on incomplete heap sort algorithm is proposed to improve the filtering speed. The new algorithm considers in detail the characteristic of image median filtering (In median filtering algorithm, the sorting operation of all pixel values is not necessary, getting the median value is the real purpose) and heap sort algorithm, and can give the median value by sorting only part of the pixels value in the neighborhood, thus it can reduce many data move operations, and then greatly improve the efficiency of image median filtering. Algorithm analysis and a lot of experiment results all show that, the new algorithm greatly improves the efficiency of image median filtering, and can keep the edge, outline, texture and much other information to a great extent.

In order to detect coal-gangue interface on fully mechanized mining face, time frequency analysis is applied to the vibration signals of top coal and gangue. This paper introduces short time Fourier transform, wavelet transform and Wigner-Ville distribution to analyze vibration signals under coal mining caving. From the spectrogram, scalogram and smoothed-pseudo Winger-Ville distribution, we can find the short time shock characteristic when coal-gangue caving, which indicates that there are gangues shock to steel plate. Experimental results show that the three time frequency analysis approaches can be used as coal-gangue interface detection well.

The atmospheric turbulence is an important factor which affects the laser atmosphere communication. Particularly, the probability distribution of the light intensity fluctuation is the focus of the research when the laser transfers in the strong turbulence or long distance transmission. And the multi-beam transmission is one of the most important ways to settle the impact on the atmospheric turbulence. This paper takes the negative exponential distribution, I-K distribution as the basis to establish the distribution model of the light intensity under the weak and strong turbulence. Moreover, it uses the test result of related document s for verification. The result shows that the simulation result agrees with the test result relatively; the distribution curve is corresponded; and the degree of fitting is relatively high. With the increase of the beams, the function value for the light intensity distribution is increased; and with the increase of the receiving aperture, the function value for the light intensity distribution is increased.

The connective eccentricity index of a graph G is defined as ξce(G) = ∑ /v ε V (G) d(ν)/ ε(v), where ε(v) and d(ν) denote the eccentricity and the degree of the vertex ν, respectively. In this paper we derive upper or lower bounds for the connective eccentricity index in terms of some graph invariants such as the radius, independence number, vertex connectivity, minimum degree, maximum degree etc. Moreover, we investigate the maximal and the minimal values of connective eccentricity index among all n-vertex graphs with fixed number of pendent vertices and characterize the extremal graphs. In addition, we study the cactus on n vertices with k cycles having the maximal connective eccentricity index.

This paper, by adopting the carbon emission calculating method for all kinds of energy proposed by IPCC in 2006, calculates the amount of carbon emissions of Shandong province. It turns out that carbon emissions in Shandong increased 2.63 times, carbon emission intensity increased 2.45 times and the carbon emission intensity and the energy intensity by GDP is obvious higher than the average level of China from 1997 to 2008.Taking into account the characteristics of carbon emissions in Shandong Province, the paper tries to propose the corresponding strategies to develop low-carbon economy. © 2011 Published by Elsevier Ltd.

Low carbon economy is the inevitable result of the capitalist production model, and is economic development model which mankind is forced to adopt. The measures to reduce carbon emissions mainly include laws and regulations, carbon taxes or carbon trading, subsidies or tax cuts on clean production, technological innovation and demand reduction. These measures have respective advantages and disadvantages. The paper believes that technological innovation and demand reduction are long-term solution of these measures. © 2011 Published by Elsevier Ltd.
