In this paper, the analysis problem of adaptive exponential synchronization in pth moment is considered for stochastic complex networks with time varying multi-delayed coupling. By using the Lyapunov-Krasovskii functional, stochastic analysis theory, several sufficient conditions to ensure the mode adaptive exponential synchronization in pth moment for stochastic delayed complex networks are derived. To illustrate the effectiveness of the synchronization conditions derived in this paper, a numerical example is finally provided. © 2013 Springer Science+Business Media Dordrecht.

This research is mainly designed and implemented the RFID middleware based on embedded Linux system. This middleware uses compositive control framework for design and development, by doing this, it makes middleware function modules can be dynamically loaded, installed and uninstalled by plug-in application form, witch will improve the flexibility and stability of the use of the RFID middleware. In the complex event processing, the paper introduced Esper engine to promoted the ability to filter, analyze, aggregate and some other complex event processing to dulling with the tagged data. This paper realized the main function module design by strictly compliance with the ALE protocol witch is made by the EPC Global Organization. The RFID middleware in this article establish the interactive interface with the external application. This middleware application can be deployed on the embedded Linux system, and it has obtained the expected effect and function after the test of this middleware application. © (2014) Trans Tech Publications, Switzerland.

As the idea of “develop next generation”s national infrastructure with broadband fusion security and promote application of the Internet of things” was clearly proposed in the 12th five-year plan of China, the Internet of things has attained an increasingly swift and violent development, and it has been extensively applied to business. However, there are problems to appear in the customer information security of websites with the development of the Internet business. This gives a reflection to “the customer information security situation of e-commerce sites based on the Internet of things is not very good at present, and should be improved”. Therefore, concrete measures are necessarily taken in the development process of the business based on the Internet of things, so that a continuous improvement is attained. © 2015 Taylor & Francis Group, London.

As a new method to understand mathematics, visualization offers a new way of understanding mathematical principles and phenomena via image thinking and geometric explanation. It aims to deepen the understanding of the nature of concepts or phenomena and enhance the cognitive ability of learners. This paper collates and summarizes the application of this visual method in the understanding of mathematics. It also makes a literature review of the existing research, especially with a visual demonstration of Euler's formula, introduces the application of this method in solving relevant mathematical problems, and points out the differences and similarities between the visualization method and the numerical-graphic combination method, as well as matters needing attention for its application. © Owned by the authors, published by EDP Sciences, 2015.

In this paper, the author considers a difference scheme of Laudau-Lifshitz equation (LL for short) and modulus of un jujn which are constantly remaining equal to 1. Using this iteration format error which is ordered to t/2h2 t2h2, the author comes to a conclusion based on several initial simulations. According to some conditions, the author gives the numerical solution, the examples of exact solution and the error comparisons of the solutions. © Owned by the authors, published by EDP Sciences, 2015.

An integrated platform based on extensible mark-up language (XML) is presented as a solution to resolving the problem concerning the integrating and interacting of heterogeneous data under a network environment. Non-barrier interaction of distributed heterogeneous data can be achieved without changing the existing way or storage type of datum sources. The structure model of the integrated platform was built up. Analysis was made on the concrete application of interface technology, network transmission technology, business process engine, and other XML technology that the model concerns. Key technology was studied to materialize the model. Problems concerning the generation, translation, and mapping of XML files were solved. The way of defining XML modes on the basis of unified modeling language modeling was put forward. © 2014 WIT Press.

With the increasingly complex of computer software system, traditional software engineering methods for major software development will inevitably produce a lot of mistakes and catastrophic consequences for key industry users. Experiment with software engineering methods cannot guarantee the behavior at infinity reliability and security of the state space. All this requires formal analysis and verification to the complex system. In protocol verification based on automatic machines, the automaton is used to represent the behavior of the system, the time automaton is a formal method can be well applied to the network protocol verification. © (2014) Trans Tech Publications, Switzerland.

Finite-time chaos control of Lorenz chaotic system applying the passive control method is investigated in this paper. Based on the finite-time stability theory and the passive control technique, the passive controller are proposed to realize finite-time chaos control of Lorenz chaotic system. The controller is robust to noise. Both theoretical and numerical simulations show the effectiveness of the proposed method. © (2013) Trans Tech Publications, Switzerland.

In this work, a novel method was developed for the determination of trace rare earth elements in biological and environmental samples by inductively coupled plasma mass spectrometry (ICP-MS) after on-line preconcentration/separation with a titanium dioxide nanotube packed microcolumn. The adsorption behaviors of the analytes on titanium dioxide nanotubes were studied systematically. The effects of the experimental parameters, including pH, sample solution flow rate and volume, eluent concentration and volume and interfering ions, on the recoveries of the analytes were examined in detail. Under the optimum conditions, the detection limits of this method ranged from 0.19pgmL-1 (Lu) to 1.2pgmL-1 (La) with an enrichment factor of 100, and the relative standard deviations (RSDs) for the determination of REEs were less than 5.0% (n=9, c=1.0ngmL-1). The linear range of calibration curve spanned three orders of magnitude. This method was validated using a certified reference material of tea leaves, and successfully applied for the determination of trace light (La and Ce), medium (Eu and Gd) and heavy (Lu and Yb) rare earth elements in real samples with recoveries of 95.5-103%. •Titanium dioxide nanotubes (TDNTs) were used as an adsorbent for preconcentration/separation of trace rare earth element.•TDNTs provide very attractive features such as large surface area, high chemical stability, non-toxicity and low cost.•This method has the advantages of high adsorption capacity, low detection limit, good precision, sensitivity and accuracy. © 2013 Elsevier B.V.

First of all, we investigate adaptive matrix projective synchronization of the chaotic system. Finally, this method is applied to secure communication through improved chaotic masking. The information signal is mixed with the chaotic signal before being transmitted, and is recovered without distortion through the synchronized receiver. Simulation results show that the scheme has a good performance. © (2014) Trans Tech Publications, Switzerland.
