Solving nonlinear equations is an important problem in engineering eld. Therefore, the study of ecient algorithm is of great signicance. Teaching-LearningBased Optimization (TLBO) has the advantages of simple algorithm, less parameters, strong global convergence ability and insensitivity to initial point, but it is weak at local optimization and slow later convergence. On the other hand, Newton method has the advantage of local deep search and fast convergence rate, but it is sensitive to the initial point. Therefore, considering advantages and disadvantages of two methods above, this paper proposes a hybrid algorithm (TNHA) based on the TLBO and Newton method for solving nonlinear equations. The hybrid algorithm both combines all these merits of the TLBO and Newton method but does not have the defects. Finally, numerical examples verify the eciency of the TNHA. © 2016 ICIC International.

To improve the global search ability under the condition of ensuring convergence speed, it is still a major challenge for most meta-heuristic optimization algorithms. The Moth-Flame Optimization（MFO） algorithm is an innovative nature-inspired algorithm. To improve the precision of the solution and to quicken the convergence speed and to increase the stability of MFO,an ameliorated Moth-flame optimization algorithm（A-MFO） that combines the crisscross optimization algorithm with MFO is proposed to solve this problems that are mentioned above. The performance of proposed A-MFO is demonstrated on six benchmark mathematical function optimization problems regarding superior accuracy and lower computational time achieved compared to other well-known nature-inspired algorithms.

This paper reports a novel electrochemical method for the detection of insulin in ultra-pure water. A screen printed electrode (SPE) modified by Nickel hydroxide was used as the working electrode, one with good activity of electro-catalytic oxidation-reduction for insulin. The SPE was modified by Nickel hydroxide using the electrodeposition method. The results showed that Nickel hydroxide was homogeneously electrodeposited on the surface of the working electrode. A coin-size electrolytic tank was fabricated with PDMS, which only requires 0.3ml of sample for the detection. The concentration of insulin was analyzed using the methods of Cyclic voltammetry (CV), Electrochemical impedance spectroscopy (EIS) and Chronoamperometry (i-t). The Nickel hydroxide used for detecting insulin showed good analytical characteristics, such as a high sensitivity of 14.797μA·μM -1 , a good linear detection range of 100nM-5μM, and a low detection limit of 93nM. This nickel hydroxide modified SPE electrode has a much smaller size and is easier to fabricate than traditional electrodes, making it a much more promising candidate for an insulin sensor.

Rail fasteners, a key component of a railway track, are used to connect the rail and the sub-rail foundation together with the required degree of elasticity. Severely loose or failed fasteners may lead to serious safety hazards for rail transportation. However, current strategies for determining fastener looseness are mainly implemented manually, which is labor-intensive, inefficient and less-than-objective. In this paper, we propose a system that uses a MEMS acceleration meter and a wireless data transmission technique to detect railway fasteners. Vibration was generated by hitting the rail with a hammer. Then the acceleration data was transmitted to the cloud by the Global System for Mobile Communications (GSM) technique. The fastener looseness was analyzed using power spectrum entropy and frequency domain analysis. Results from the field experiments show that our method can identify the fastener's loosening state accurately and automatically. This wireless, low-cost fastener inspection system is expected to provide an effective approach to improving the efficiency of regular railway maintenance..

Real sense image generation algorithm is an important part of computer graphics, in which realistic terrain generation has become a difficulty and hot spot in recent years. Virtual three-dimensional terrain modeling uses computer graphics technology to implement. In this paper, based on fractal Brownian motion theory, the classical Diamond-Square algorithm was advanced to form virtual three-dimensional terrain modeling. Terrain Splicing and Stitch Border techniques and terrain texture mapping, light mapping technique were used to deal with the terrain light and texture and stitch the border. The algorithm parameters were also analyzed in this paper and the influence effects of the various parameters on the virtual terrain features was got. With the combining use of Visual C++ 2005 and OpenGL, terrain generation and rendering are achieved. This approach has reached the expected results and a realistic three-dimensional graphics effect was obtained.

Fuzzy dynamic output-feedback control problem is investigated for a class of fuzzy bilinear systems with Markovian jumping parameters. The transition probability matrix is assumed to be partly unknown. Based on Takagi-Sugeno (T-S) fuzzy bilinear model, a nonlinear dynamic output-feedback controller is first constructed, and in terms of linear matrix inequalities techniques, the sufficient conditions on the stochastic stability of the closed-loop fuzzy bilinear jump system are presented and proved. Finally, a numerical example is provided to illustrate the effectiveness of the proposed method. ©, 2015 ICIC Express Letters *** Rights Reserved.

In this paper, the technology of ZigBee based on wireless sensor network was adopted to carry out the real-time oxyhemoglobin saturation monitoring. C8051F340 was used to control UZ2400 as MCU(Micro control Unit). Electricity was consumed less than 2mA when it worked and electricity was consumed less than 1μA when it slept. This system can prolong the life time of battery effectively. And the system avoided tedious A/D conversion which the traditional sensor needs and its measure precision is good.

ICIC Express Letters 2015年第9期9卷 2467-2473页

作者： Shi, Shengli Li, Jianxiong Fang, Yiming Key Laboratory of Industrial Computer Control Engineering of Hebei Province Yanshan University No. 438 Hebei Avenue Qinhuangdao China College of Science Yanshan University No. 438 Hebei Avenue Qinhuangdao China

The position tracking control scheme is investigated in this paper for electrohydraulic servo system with parameter uncertainties, external disturbances and actuator saturation. Disturbance observer is employed to estimate the compound disturbance, and robust backstepping control law based on the disturbance observer is designed to ensure the system output tracks the reference signal. A second-order integral filter is proposed to avoid the repetitive differentiation of the virtual control. The robustness of the controller is guaranteed by robust items, and the tracking performance can be achieved by the proposed method. Simulation results are presented to verify that the control strategy can realize good position tracking. © ICIC International 2015.

作者： Chengyu Yao Zhen Dang Dongning Chen Shijun Lv Key Laboratory of Industrial Computer Control Engineering of Hebei Yanshan University Qinhuangdao China Key Laboratory of Heavy Machinery Fluid Power Transmission and Control of Hebei Province Yanshan University Qinhuangdao China

In order to overcome the characteristics of uncertainty and incomplete information of fault attribute in searching for fault, a new fault search method based on the fault tree and grey fuzzy multi-attribute decision-making is proposed in this paper. Firstly, utilizing fault tree analysis (FTA) method to determine the initial fault alternative, fault probability and search cost of the fault alternative are considered as fault attributes simultaneously, the attribute value of fault alternative is described as grey fuzzy numbers, calculating the attribute weight by the information entropy method. Then, the grey relational grade between the fault alternative and the ideal alternative is calculated base on grey relational analysis method, and relative closeness of fault alternative is achieved. Finally, according to the relative closeness determine the search order of all fault alternatives. An engineering example of the hydraulic suspension system of a certain type truck is adopted to demonstrate the feasibility and accuracy of the proposed method.
