An improved (G'/G)-expansion method is proposed to seek more general travelling wave solutions of nonlinear evolution equations. We choose the Zakharov-Kuznetsov-BBM (Benjamin-Bona-Mahony) equation and the (2+1)-dimensional dispersive long wave equations to illustrate the validity and advantages of the proposed method. As a result, many exact travelling wave solutions are obtained, which include soliton, hyperbolic function, trigonometric function and rational, solutions. © 2010 Taylor & Francis.

The phosphoric acid groups has been successfully grafted on the surface of mesoporous molecular sieve SBA-15 to form a solid acid catalyst P-SBA-15 by post-synthesis method. The samples were characterized by means of XRD, FT-IR, SEM, TEM, 31P MAS NMR, NH3-TPD, N2 adsorption/desorption and the esterification reaction. The XRD and N2 adsorption/desorption results indicate that P-SBA-15 catalyst keeps the 2D hexagonal mesoporous structure and opens channels with the lower surface area of 554.35 m2/g compared with that of SBA-15. The SEM and TEM results show that the figuration of P-SBA-15 behaves "rod-like" and phosphoric acid groups is scattered differently on the surface of P-SBA-15. The FT-IR and 31P MAS NMR results display that phosphorus species graft onto the surface of SBA-15, which provide the Brønsted acid sites on the surface of P-SBA-15. The acidity of the generated Brønsted acid sites on P-SBA-15 significantly is verified by NH3-TPD. The esterification reaction results shows that catalytic activity of P-SBA-15 is enhanced significantly compared with that of SBA-15, and its stability is good. © Springer Science+Business Media, LLC 2011.

Double-perovskite Sr2-xSmxMgMoO6-δ (SSMM, 0 ≤ x ≤ 0.8) is investigated as a possible anode material for solid-oxide fuel cells on La0.9Sr0.1Ga 0.8Mg0.2O3-δ (LSGM) electrolytes. Single-phase SSMM samples with 0 ≤ x ≤ 0.4 are prepared. At x ≥ 0.6, a small amount of SrMoO4 and Sm2O3 impurities are observed. The Mg/Mo ordering in SSMM decreases with increasing Sm content. Substitution of Sm for Sr significantly improves the electrical conductivity of SSMM. At x = 0.6, the sample yields the highest conductivity, with values reaching 16 S cm-1 in H2 at 800 °C. The maximum power densities of single cells achieved with x = 0.0, 0.2, 0.4, 0.6, and 0.8 anodes on a 300 μm-thick LSGM electrolyte are 693, 770, 860, 907, and 672 mW cm -2, respectively, in H2 at 850 °C. The SSMM sample with x = 0.4 is considered as the best anode candidate because of the impurity formation seen in x ≥ 0.6 samples. The x = 0.4 sample not only has a thermal-expansion coefficient closer to that of the LSGM electrolyte but also exhibits good electrochemical performance and stability in commercial city gas containing H2S, where the maximum power density achieved is 726 mW cm-2 at 850 °C. © 2011 Elsevier B.V.

As an analytical method, the effective-field theory (EFT) is used to study an Ising spin system in a transverse magnetic field under a time oscillating longitudinal field. The effective-field equations of motion of the average magnetization are given for the square lattice (Z = 4). In the longitudinal field amplitude h0 / Z J-transverse field Γ / Z J plane, the phase boundary separating the dynamic ordered and the disordered phase also has been drawn, and there is no dynamical tricritical point on the dynamic phase transition boundary. The dependence of the critical temperature on the transverse field is calculated and phase diagrams are presented. We also make the compare results of EFT with that given by using the mean field theory (MFT). © 2010 Elsevier B.V. All rights reserved.

This paper describes the application of a linear iterative design of nonlinear predictive functional control for chamber pressure of industrial coke furnace. The control target is to maintain the chamber pressure of a coke furnace within a set range while rejecting the effect of disturbances (mainly the coke removing process and the switch of coke towers).The proposed control is easy to implement, as it selects a simple structure and a linear iterative approach instead of nonlinear control schemes to improve control performance in such a way that results compared with traditional PID controllers are improved. Application of industrial plant demonstrates the efficiency of the method. © 2010 Elsevier Ltd. All rights reserved.

This paper is concerned with the problem of norm-bounded uncertain perturbed discrete systems(NUPDS) with both state and input delays.Based on constructing a quadratic Lyapunov function, a delay-dependent criteria, which is expressed in terms of linear matrix inequalities(LMIs), has been proposed to guarantee the asymptotic stability of the system.Compared with existed open literature, this paper suggests a novel controller design method, which deals with more aspects including time-varying parameter uncertainties, perturbation, state and input time-delays.In addition, we also consider the condition of operating region is outer approximated by extended ellipsoids, which can be ultilized for dealing with the perburbed term of the system. The solution of the LMIs can be obtained easily by using existed efficient convex optimization techniques. In the end, a numerical example is given to illustrate the effectiveness of the proposed theoretical result. © (2012) Trans Tech Publications, Switzerland.

The mean-field theory (MFT) is used to study the dynamical response of the mixed spin-1 and spin-3/2 Ising model with Fe4N structure in the presence of a sinusoidal oscillating magnetic field. The Glauber dynamic is used to describe the time evolution of the system and the mean-field dynamic equations are given. Dynamic phase transition diagrams are presented in the T/|J| - h0/|J| plane. The dependence of the phase diagram on single-ion anisotropy strengths is also studied by the MFT. Besides second-order phase transition, lines of first-order phase transition, the dynamic tricritical point and the critical end point are found. In particular, the system exhibits first-order-order phase transitions, which cannot be found in previous studies in the mixed spin-1 and spin-3/2 Ising model using the MFT. © 2014 Elsevier B.V.

Abstract The effective-field theory with correlations based on Glauber-type stochastic dynamic is used to study the dynamic compensation behavior of the mixed spin-1 and spin-3/2 ferrimagnetic Ising model. The system is a layered honeycomb structure in which two kinds of spins (spin-1 and spin-3/2) occupy sites alternately. This is related to the experimental works of a molecular-based magnetic multilayer film, AMIIFeII(C2O4)3(A = N(n-CnH2n+1)4,MII=Mn,Fe). The system is in the presence of a sinusoidal oscillating magnetic field and the Glauber dynamic is used to describe the time evolution of the system. The effects of the interlayer coupling and a crystal-field constant of the spin-1 sublattice on the compensation temperature are investigated. Dynamic phase diagrams, including the compensation points are presented. Besides second-order phase transition, lines of first-order phase transition, the dynamic tricritical point, the dynamic zero-temperature critical point and the multicritical point are found. The dynamic tricritical point, the dynamic compensation point and the non-magnetic phase predicted by the mean-field theory are confirmed by the effective-field theory. © 2015 Elsevier B.V.

The river remote monitoring system in China is manual data collection, the disperse monitoring stations and the lag data transmission. The statistic showed that 90% reach through the city was polluted and 70% lake was eutrophied .So in this paper the Wireless Sensor Network (WSN) in the Monitoring of Fushun Reach Water Quality was studied, which involve the confirmation of polluted sources, Network System construction, the implementation of data transfer system. First Fushun city, as a typical industrial city, is crossed by Hunhe River. A new remote river quality monitoring system based on the wireless sensor network (WSN) design was introduced herein for its low power consumption, long lasting operation time, lower cost, self-communication and ease of implementation in large area. Then the detailed solution concerning system structure, network node, data acquisition process and its remote sensing abilities were discusses. Moreover when the pollution emergencies occur, the environmental department could detect on-time and dispose quickly. But now the some front-end analytical instruments are still in the early stage. At Fushun the current automated water quality sensors can not cover all the important water quality parameters. Manual sampling and laboratory analysis are necessary supplement to the WSN system in order to gather all the necessary data. © 2010 IEEE.

The effective-field theory (EFT) is used to study the dynamical response of the kinetic spin-1 BlumeCapel model in the presence of a sinusoidal oscillating magnetic field. The effective-field dynamic equations are given for the honeycomb lattice (Z=3). The dynamic order parameter, the dynamic quadruple moment, the hysteresis loop area and the dynamic correlation are calculated. We have found that the behavior of the system strongly depends on the crystal interaction D. The dynamic phase boundaries separating the paramagnetic phase and the ferromagnetic phase are obtained. There is the region of the phase space where both a paramagnetic phase and a ferromagnetic phase coexist. The dynamic transition from one region to the other can be of first or second order depending on the frequency of the magnetic field. There is no dynamic tricritical point on the dynamic phase transition line. The results are also compared with those obtained from the mean-field theory (MFT). © 2011 Elsevier B.V.
