Published: May 2014

A fuzzy control algorithm of selective roll cooling was developed dependent on a qualitative knowledge possessed by skilled operators. The residual flatness deviation as well as the time and spatial variation in the deviation of flatness were chosen as linguistic sets in the fuzzy control algorithm. Limitation and membership function as well as reasoning rule of the fuzzy sets were determined in accordance with the practical process. Besides, linguistic variables were classed by taking into account the condition of practical rolling process. The fuzzy control algorithm utilizes the Mamdani reasoning method and MAX-MIN composition method to actualize fuzzy reasoning and uses weighted mean method to actualize evaluation of fuzzy output. The applications show that the fuzzy control algorithm of selective roll cooling is capable in flatness control and is significant to obtain better flatness.

Modeling of TWIP Steel Tensile Behavior with Crystal Plasticity Finite Element Method
Authors: Wang Yuan Yuan , Sun Xin , Wang Yan Dong , Hu Xiao Hua , Zbib Hussein M.
Published: May 2014

We developed a plane-strain crystal plasticity finite element (CPFE) numerical model to predict the tensile behavior of twinning-induced plasticity (TWIP) steel with both slip and mechanical twinning as the main deformation modes. Our CPFE model may not only predict well the tensile stress versus strain (S-S) curve but also capture the variation in the volume fraction of twins with a reasonable accuracy. The nucleation of mechanical twin is obviously controlled by the stress concentration. At the same time, the growth of twin may either lead to a stress relaxation in the matrix or cause a local stress concentration around twin, which depends on the deformation condition.

Authors: Liao Zhen Yu , Li Jing , Shen Chong
Published: May 2014

This Marine mobile ad-hoc network (MMANET) is a dynamic wireless network, and the random mobility of ship nodes and limited radio transmission range are the main challenges in the design of the robust routing algorithm. Dynamic Source Routing (DSR) and Ad hoc On-Demand Vector Routing (AODV) are typical on-demand protocols, but if there are some nodes moving with random fast velocity and limited transmission range in communication network, the network will be under an unstable link state and this situation may lead to large delay and packet loss. In this paper, a new scheme named Dynamic Link Self-healing mechanism on the basis of Mobility Quantization AODV (DLMQ-AODV) is proposed to solve the problem. Mobility quantization of node is resulting from relative velocity and distance, through computation of weighting, dimensionless etc. We take advantage of mobility quantization to establish dynamic link self-healing mechanism in order to improve the routing performance. The simulation results show that DLMQ-AODV has a better performance in comparison to DSR and AODV.

Authors: Xu Su Qin , Xu Yi Tao , Jiang Han , Gao Xiang , Luo Kang
Published: May 2014

Cognitive radio (CR) is a promising technology which has the potential to utilize the scarce spectrum resources with high flexibility and efficiency. It’s well accepted that cooperative spectrum sensing (CSS) with numbers of cognitive users (CUs) located in a wide geographical area can achieve much better sensing performance. However, some CRs may misbehave and provide false sensing information in order to deteriorate the system’s performance. This misbehavior is known as spectrum sensing data falsification (SSDF) attack. In this paper, we propose a secure spectrum sensing scheme using peer-assessment to detect malicious CUs and filter their spectrum sensing results out of the final decision making process. The robustness and efficiency of the proposed scheme are verified through extensive computer simulations in presence of SSDF attacks.

Cloud computing has offered a brand-new perspective to scalable, distributed computing, which allows significant reduction in IT costs and increase in capabilities. At the same time, however, due to the openness of accessible information relying on trust between cloud providers and customers, the problem of data security has been amplified under the cloud model. This paper investigates the security problem and some of the key challenges of implementing security solutions.
Research on Information Hiding Method Based on Word Text
Authors: Wang Xiao Feng , Li Hai Jian
Published: May 2014

This paper proposes an information hiding method based on word text, according to the theory of the human eye cones for the color sensitivity; the human eye is least sensitive to blue. I change the lowest two bits of G component in the carrier text character RGB color value, change the lowest two bits of R component in the carrier text character RGB color value, and change the lowest four bits of B component in the carrier text character RGB color value, So that each carrier text character can hide 8 bits binary information. RGB color value of character underline can hide 24 bits information; the combination of these two methods can hide 32 bits binary information. After testing, the results show that the algorithm hiding rate is high, the algorithm is stable and easy to implement, has a certain application value.

A New Data Stream Clustering Approach about Intrusion Detection
Authors: Li Zhuo Qun
Published: May 2014

Intrusion detection is one of the most important techniques for protecting network security. In addition, intrusion detection model can be used to recognize real-time pattern, which has important practical significance for real-time intrusion detection. However, due to the sheer speed and scale of the data, data points must often be analyzed in real time. The one-pass-through requirement and the lack of efficient clustering algorithms to identify intrusion patterns limit the power and scalability of this approach. A data stream clustering algorithm is proposed for real-time network intrusion detection. By introducing the new hashing mechanism, the method can quickly find the clustering patterns in the data stream. The method significantly reduces the false alarm rate of intrusion detection, and improves the performance of intrusion detection system.

Published: May 2014

Of all the active learning research, the study on the active learning algorithm for SVM is much less. In this paper, based on K-Nearest Neighbors (KNN), we propose a new SVM active learning algorithm. The algorithm first collects the potential informative samples to form a potential informative sample set, and then in this sample set, based on KNN it evaluates the sparseness for each sample. The sample that locates at a sparser region is taken as an informative one, and is selected for training. Experimental results show that the proposed algorithm can greatly improve the classification performance, and can efficiently accelerate the convergence of the classifier.

Authors: Wang Feng , Zhang Kun Fan , Meng Fan Kun , Zhao Yong Jun
Published: May 2014

The basic principle of the NAS-RIF algorithm is described and this algorithm has a simple structure, but it tends to amplify the noise and produce excessive smoothing in the iterative process. This paper takes some measures and focuses on overcoming these shortcomings. Firstly we use an adaptive denoising method based on total variation to reduce noise in turbulence-degraded images. Then, a regularized term is added into the cost function to preserve the edges effectively and a new form of the cost function is also improved to guarantee the convergence of the algorithm. Comparing with the traditional NAS-RIF algorithm, the proposed algorithm has a positive improvement in restraining the noise enlargement, preserving the detail features and the image restoration effect is obviously better.

Authors: Wang Qiao , Li Jin Liang , Fu Ai Ping , Li Hong Liang
Published: May 2014

Emulsifier-free emulsion polymerization is a technique derived from conventional emulsion polymerization in which polymerization is carried out in the absence of emulsifiers. This technique is useful for the preparation of polymer colloids with narrow particle size distributions and well defined surface properties. Emulsifier-free emulsion polymerization eliminates the disadvantages of conventional emulsion polymerizations stemming from the use of emulsifiers, e.g. impurities in products caused by residual emulsifier and poor water-resistance of films induced by polymer latex.
