Authors: Wan Li , Zhou Qing Hua
Published: February 2011

Although ultimate boundedness of several classes of neural networks with constant delays was studied by some researchers, the inherent randomness associated with signal transmission was not taken account into these networks. At present, few authors study ultimate boundedness of stochastic neural networks and no related papers are reported. In this paper, by using Lyapunov functional and linear matrix inequality, some sufficient conditions ensuring the ultimate boundedness of stochastic neural networks with time-varying delays are established. Our criteria are easily tested by Matlab LMI Toolbox. One example is given to demonstrate our criteria.

Authors: Li Fang , Zhong Ying Chun , Qi Jian
Published: February 2011

An intelligent algorithm is proposed to extract the fascicular groups regional image from the nerve slice image. First, some pixels in the original image are selected arbitarily and their gray level comatrix with different neighbourhood scale are calculated in order to establish the texture feature matrix. Second, the rough k-means is employed to cluster all the arbitarily selected pixels. The arbitarily selected pixels which are located in fascicular groups area would be classified in the same cluster. Then, the convex hull of those pixels located in fascicular groups is calculated in order to extract the regional image. The experiments show that the new proposal not only can be quick and accurate to extract the fascicular groups regional image but is independent on modifying the parameter while processing other nerve slice images, which reflects the new algorithm has good adaptability.

Authors: Deng Zhi An , Xu Yu Bin , Wu Di
Published: February 2011

Indoor positioning system in wireless local area network (WLAN) has been a subject of intensive research due to its cost effectiveness and reasonable positioning accuracy. A new WLAN indoor positioning algorithm based on support vector regression (SVR) and space partitioning is proposed. The whole positioning environment is partitioned into several subspaces by combining k-means clustering method and binary support vector classifiers (SVC). Then the mapping function between received signal strength (RSS) and the physical space is established by SVR machine for each subspace. Subspace with much smaller physical range means more compact input feature space and leads to the enhancement of generalization capability for each SVR machine. The proposed algorithm and other well-known positioning algorithms are carried and compared in a real WLAN environment. Experimental results show that the proposed algorithm achieves 14.6 percent (0.31m) improvement than the single SVR algorithm in the sense of mean positioning error.

Authors: Gu Qiao Lun , Gao Tie Gang
Published: February 2011

In this paper, we focus on the price decisions of the wholesale price, the retail price and the collecting price for the closed-loop supply chain with and without competition. We obtain the optimal decisions based on two models: Model I without competition and Model II with competition. By the analysis of a numerical example, we find that the competition between the manufacturers in model II will affect their prices decisions and their profits; in model II, the two manufacturers would like to halve the market while the retailer hope to increase the difference of their market shares, and the two manufacturers would not like to increase the substitute ratio of their products while the retailer can benefit from that. So, from the manufacturers’ point of view, they should avoid the competition risk by choosing the independent retailers.

Scalable Video Coding Bit Stream Extraction Based on Equivalent MSE Method
Authors: Qian Da Xing , Wang Hong Yu , Niu Fang Lin
Published: February 2011

The bit stream extraction plays an important role in Scalable Video Coding (SVC) [1]. However, one downside of current video coding methods is to ignore the video contents which is in fact an important factor for video coding efficiency. Therefore, an equivalent MSE method is proposed in this paper to extract substreams in the temporal and spatial enhancement layers. When the Motion Vectors (MVs) are large in one video, a larger frame rate is necessary to maintain the continuity of the object movement which makes no jump in the visual sense. In this sense, substreams extraction in temporal enhancement layer has to be satisfied. On the other hand, if there are some larger high-frequency components in a single frame of the video, that is to say, there are some higher spatial details in the video stream. As a result, it should try to meet the extraction requirement in spatial enhancement layer. This method has the advantage of considering the contents of the video, which can effectively improve the coding performance and quality. The experimental results have demonstrated the improved quality of reconstructed video for the equivalent MSE method when extracting bit stream arbitrarily at the same bandwidth.

The Effect of Low Extracellular Potassium on Cardiac Arrhythmia Vulnerability: A Computer Simulation Study
Authors: Cao Li Ping , Jin Yin Bin , Zang Hong , Yang Lin
Published: February 2011

Unidirectional conduction block of cardiac excitation wave is one of the necessary conditions leading to initiation of reentrant arrhythmia. Temporal vulnerable window (VWtime) is an important measure for arrhythmia vulnerability. In this study, we examine theoretically how low extracellular K concentration ([K]o) control the VWtime by a single premature extrasystole. A numerical modified LR91 one dimensional heterogeneous ventricular model is used to quantitatively investigate the relation of low [K]o with conduction velocity (CV), VWtime, and electrical dynamic factor CV restitution. Morever, we characterize the distribution of Na channel conductance (gNa) and gating factors of premature beat applied at different time of the VWtime with different [K]o. The results show that lowering [K]o enlarge the VWtime magnitude gradually. The CV of S1 beat slows down with the [K]o in a reverse-[K]o dependent manner. Low [K]o promote the recovery of maximum Na conductance (GNa) from inactivation. However, decreasing [K]o can increase heterogeneity of gNa along the cable, and modulate CV restitution curve, which induce larger transmural dispersion of refratoriness for the premature beat and enlarge the VWtime.

Characters on license plate, which is obscured by water or mist, is hard to be recognized through classical license plate recognition technology. In order to get higher recognition rate of blurred character in practical license plate recognition system, an approach to separate characters from a blurred image of vehicle license plate is proposed in this paper. At first, the upper, lower, left and right boundaries of blurred character are assumed to be foreground sample; the broken boundary of character is considered as background sample. At the position of background white scribbles are drawn; in contrast, midpoints of the lines along foreground are painted with black scribbles. Then a scribble image is generated automatically. Furthermore, closed form solution to natural image matting is adopted to obtain the background that is uncovered license plate according to the scribble image. The experiments show that the new algorithm is applicable and helpful to get higher recognition rate of blurred license plate.

Research on Stress Testing for Physical GAP
Authors: Liang Zhi Hong , Lin Qin Liang
Published: February 2011

The physical gap is a kind of security protection products that can guarantee information security by disconnecting the connections between the intranet and the extranet. It’s commonly deployed between the secret-related network and the Internet to protect information security. Because of the market demand, a lot of gaps are produced, but without strict quality control. However, the importance of the physical gap’s quality and stability continue to grow with the intensification of competition in the marketplace. In addition physical gaps may exhibit failures or degrade only under certain stress conditions in most cases. So it’s necessary to conduct test especially stress test for the physical gap. In fact, the most effective way to qualify a physical gap and to assure whether a physical gap meets its stability and quality goals is through stress testing. In this paper, we discuss why and how to qualify a physical gap through stress testing. We also presented a stress testing case designed for the physical gap to show how to conduct stress testing and analyze the testing result. To the best of our knowledge, there is a lack of research about conducting stress test for physical gap to date.

Thermal analysis of aircraft hydraulic systems is an important subject for system’s design. Heat generation and dissipation of aircraft hydraulic systems had been discussed in this article. Heat exchange was calculated based on heat transfer theory. A formula of temperature variation was derived based on the assumption that oil flow in the hydraulic system was one-dimension unsteady flow. Take the hydraulic system of a certain commercial aircraft for example, a model was established to simulate the temperature change of aircraft hydraulic systems based on AMESim. The simulation results are in consistent with test data.
Fault Diagnosis Analysis of Gear Based on Fuzzy Fault Tree
Authors: Yao Zheng , Wang Zhao Hua
Published: February 2011

The complexity of modern equipment is higher than before, thus it cannot meet the need of speedy fault diagnosis to use single diagnosis pattern. According to these troubles, a fault tree was introduced to analyze fault information of gear. Fault tree analysis is a logical and diagrammatic method to evaluate the probability of an accident resulting from sequences and combinations of faults and failure events. In conventional fault tree analysis, probabilities and consequences are treated as exact values. In many engineering applications, however, it is difficult to evaluate the probabilities and consequences from past experiences, so a fuzzy set defined in probability is proposed. The principle of fuzzy diagnosis is taken as basics and symptom sets and faults sets are extracted through fault tree analysis. Experiments show this method is effective for fault diagnosis of gear.

An Effective Adaptive Autocorrelation-Based Neighboring Matching Location-Aware Computing in WLANs
Authors: Xu Yu Bin , Zhou Mu , Ma Lin
Published: February 2011

The recent advances of ubiquitous wireless infrastructures and requirements for high speed context-aware computing have created the opportunities to supply the high efficient location based service (LBS) in indoor wireless local area network (WLAN) environment. Because of the serious multi-path effect, unpredictable co-channel interference and inherent equipment noise, the measured signal strengths vary a lot in the real-world indoor environment. And this strength variation will also result in the performance deterioration of radio map-based neighboring matching algorithm. In response to this compelling problem, we propose the adoption of adaptive autocorrelation-based signal preprocessing method as a specific solution by effectively eliminating the singular strength from the original fingerprint set. Finally, the feasibility and effectiveness of autocorrelation-based preprocessing are also verified by decreasing about 33.4% and 32.9% of errors in k nearest neighbor (KNN) and weighted KNN (WKNN).

The purpose of this research is to solve stress calculation problem of the composite pipe of multihole steel pipe and polyethylene of raised temperature (PE-RT). The formulas, used to calculate the burst pressure of the composite pipe, were established separately based on three kinds of different strength theories, and also the formula, used to calculate axial stress was developed based on the deviator strain energy theory. The calculation results were compared with the measured values. It shows that the calculation results of formula based on the deviator strain energy theory are very close to the measured values. This conclusion has important meaning to the heating directly buried installation of the composite pipe.
A Formal Game-Theoretic Model for Rational Exchange Protocol
Authors: Tao Xiu Ting , Gu Yong Gen , Li Guo Qiang
Published: February 2011

A rational exchange protocol is a useful protocol in which two (or more) strange parties exchange their items successfully in a way that every rational party has enough reasons to follow the protocol faithfully rather than deviate from it. This means neither parties of the protocol can gain an advantage by deviating from the protocol, but he may bring a disadvantage to the other party even if who is correctly behaving party. We introduce game theory as a formal framework in this paper. We give a formal definition for the rational exchange related to the concept of the subgame perfect equilibrium of an extensive game. We use our model to analyze the Syverson protocol by the game tree and show the relationship with Buttyan's Model.
