2013 International Conference on Communication technology (ICCT 2013)

作者： Mengzhou Gao Dongqin Feng Jian Chu Institute of Cyber-Systems and Control State Key Laboratory of Industrial Control Technology Zhejiang University

Time synchronization protocols are widely used in industrial control systems. As the development of network technology, various types of attacks have occurred. Among them, delay attacks are less studied. In this paper, we described an effective way for delay attacks which were achieved by a Man-In-The-Middle attack of asymmetric delays. To find inherent relationships between attackers and defenders, we proposed a two-person noncooperative game theoretic model. Based on Expected Utility Maximization, the mixed-strategy Nash equilibrium(NE) was resolved. The expression of probability distribution under NE indicates potential relationships between mixed-strategy probability distributions, attack costs, defence costs, and provides evidence for security and risk management professionals.

We have developed a rapid, simple and label-free colorimetric method for the identification of target DNA It is based on loop-mediated isothermal amplification（LAMP）. Plain gold nanoparticles（AuNPs） are used to indicate the occurrence of LAME The amplified product is mixed with AuNPs in an optimized ratio, at which the deoxyribonucleotides（dNTPs） bind to the AuNPs via ligand-metal interactions and thus enhance AuNPs stability. If a target DNA is amplified, the dramatic reduction of the dNTPs leads to the aggregation of AuNPs and a color change from red to blue. The success of the method strongly depends on the ionic strength of the solution and the initial concentration of dNTPs. Unlike other methods for the identification of isothermal products, this method is simple and can be readily applied on site where instrumentation is inadequate or even lacking.

The aims of this work were: to select informative variables for modeling near-infrared spectra to soil nitrogen (N) and organic carbon (OC) and to provide interpretation for the selected variables. The dataset that consisted of 225 soil samples was spilt into calibration set, validation set and prediction set by Knennard-Stone algorithm. Spectra in calibration set were conducted for variable selection by the method of Monte Carlo uninformative variable elimination (MC-UVE) and successive projections algorithm (SPA). Partial least squares regression (PLSR) and multiple linear regression (MLR) were used to construct calibration models for each property based on the selected variables. The proposed method MC-UVE-PLSR achieved the optimal performance for soil N and OC comparing with full-spectrum PLSR and SPA-MLR. The coefficients of determination (R2), residual prediction deviation (RPD) were respectively 0.86, 0.87, and 2.8, 2.7 for N and OC. The results indicate that MC-UVE is an effective tool for spectral variable selection, and is able to promote model prediction accuracy and efficiency. Analysis of the feature variables show that some of the selected variables of soil N and OC are directly related to their functional groups, while some influence the results by measuring the correlation constituents of N and OC. It is also suggested to adopt its own spectral response for the prediction of soil N instead of calculation by the autocorrelation of soil OC.

This paper presents a L 2 -L ∞ filtering scheme for nonlinear discrete-time Markovian jumping neural networks with time delay under missing output measurements. By constructing appropriate Lyapunov-Krasovskii functional and utilizing some linear matrix inequality techniques, the mean square stability of the stochastic estimation error systems is guaranteed and a sufficient condition is established to ensure the given L 2 -L ∞ filtering performance. What's more, we provide the design approach of the filter when the delayed states in output measurements are involved or output measurements of the systems can be fully obtained. The gain matrix of the filter can be derived from the solution of a set of linear matrix inequalities. Finally, the simulation proves the availability of the proposed approach.

Application servers (AS) of virtualized platform may suffer from software aging problem. In this paper, we first formulate the system model including three virtual machines. Two of them act as the main servers, and the third machine acts as the backup node. The motivation of our formulated model is that the relationship between the service provider and the service maintainer is collaborative as well as having different goals between them, the service provider as a leader wants to maximize his system availability, while the service maintainer wants to minimize his maintenance cost. Thus, the problem of maximizing availability and minimizing cost between the service provider and service maintainer is Stackelberg game based. Next, we assume that the AS degradation is caused by resource consumption due to memory leaks for the AS on the active VMs, and we present the system degradation states based on Markov renewal processes. We give the analytical definitions of threshold levels for R alert at each VM, which are used to determine the optimal rejuvenation schedules. In addition, we obtain the steady-state availability expressions for the system and the mean maintenance cost. Finally, we give the Stackelberg strategy with the open-loop information and the solutions for the game theory by a numerical illustration.
