Worm detection system must detect worms efficiently and effectively. Current detection methods are mainly based on the property of low successful connections rate of worms. However, they may neglect worms if worms insert successful connections deliberately. Because the size in packets or bytes of normal TCP connections is heavy-tailed, we present a detection method by combining detection criteria of failed connections and heavy-tailed distribution of connection size for a given local host. It is more difficult for worms to evade. The method can decrease false negative and positive rates. The experiments show that our method can detect scanning worms with high efficiency and effectiveness.

As an extension of WWW, Web-based collaborative virtual environment is a next generation interface, for collaborators geographically dispersed to work together. Virtual reality modeling language, a kind of description language for 3D worlds, is appropriate for constructing, distributing, and rendering a shared 3D world of CVE system over WWW. However, the current VRML technology does not support multi-user directly and all VRML contents per se are collaboration-unaware. To supply the gap between VRML world and CVE system, Java technology is integrated with VRML through an interface called external authoring interface (EAI) provided by VRML language. This paper analyses the requirements and design considerations of generic CVE system; then it presents generic system architecture for CVE systems. Based on these design considerations and requirements, this paper proposes a new Java-based framework for web-based CVE which adopts VRML language to construct, distribute and render a shared 3D world over the Internet, and integrates Java with VRML through EAI to manage and control the virtual world to support multi-user collaboration.

It is effective to avoid falling into local optimums at the original stage of the computation that the knowledge of multi-optimum distribution state is introduced into general programming of the particle swarm movement in particle swarm optimization algorithm. But if the proportion factor of multi-optimum programming can not be dynamic adjusted in the optimization process, the performance of the algorithm is limited. In this paper, fuzzy logic was introduced into the process of multi-optimum dynamic programming, and a kind of particle swarm algorithm based on fuzzy logic and multi-optimum programming was put forward and simulated. Simulation results show that, the general convergence character of the algorithm derived in this paper has better performance than traditional PSO, fuzzy adaptive PSO and static multi-optimum programming PSO algorithm proposed by authors previously.

This paper proposes a new architecture of self-learning fuzzy-neural-network (SLFNN) for water injection control in a turbo-charged automobile. The major advantage of SLFNN is that no off-line training is needed for initialization. The SLFNN will initialize itself with a random set of initial weighting factors (normally zeros) and a specifically designed on-line optimal training algorithm is invoked immediately after the engine of the automobile is turn on. The on-line optimal training can guarantee that the weighting factors will be directed toward a maximum-error-reduced direction. Although this SLFNN can also be used as a controller for fuel injection, we adopt the SLFNN as the water injection controller to reduce the knocking effects of a turbo-charged engine and therefore the emission is cleaner with less petrol consumption. Real implementation has been performed in a Saab NG 900 (1994 -1998) automobile with excellent results.
提出了一种用于涡轮增压汽车注水控制的自学习模糊神经网络(SLFNN)结构。SLFNN的主要优点是初始化不需要离线训练。SLFNN将使用一组随机的初始加权因子(通常为零)初始化自身，并且在汽车发动机启动后立即调用专门设计的在线最优训练算法。在线最优训练可以保证权重因子向误差减小最大的方向运动。虽然该SLFNN也可以用作燃油喷射控制器，但我们采用SLFNN作为注水控制器来减少涡轮增压发动机的爆震效应，因此排放更清洁，汽油消耗更少。在Saab NG 900(1994 -1998)汽车上进行了实际实施，取得了良好的效果。

This paper proposes analysis of wavelet correlation between tyre sounds and tread patterns. In the paper, wavelet analysis provides the visualization of tyre sounds in time-frequency domain and allows the tyre sounds to be analyzed in synchronization with tread patterns. We focus on the influence of variable lateral grooves' pitches on the pipe resonance of a tyre sound. Based on the model that the amplitude of the resonant component is modulated by lateral grooves, the correlation between the pipe resonance and the pitch fluctuation is analyzed using wavelet transform. Consequently, the tread's area on the circumference, which contacts the ground, is specified for each time point on the tyre sound data.

Based on elementary siphons of Petri nets and the mixed integer programming approach, an improved deadlock prevention policy is developed for S/sup 3/PR. Siphons in such a plant Petri net model are divided into elementary and dependent ones. Our policy consists of two stages: siphon control and control-induced siphon control. At first stage, a monitor (control place) is added for each elementary siphon such that it is invariant-controlled. Due to the addition of monitors to plant model, control-induced siphons are possibly generated in the augmented S/sup 3/PR, which is an RCN-merged net. The second stage sees that monitors are added to make always marked control-induced siphons in the resultant RCN-merged net without generating new control-induced siphons. Compared with our previous work, the deadlock prevention policy developed in this paper can lead to a structurally simple liveness-enforcing Petri net supervisor by adding only a small number of monitors and arcs. An FMS example is utilized to illustrate the proposed methods.

Dynamic O-D flows between entry and exit are important input data of freeway management systems, and are difficult to get. This paper reviewed the evolution process of dynamic O-D flows estimation, put forward integrated and simplified calculation methods of dynamic route travel time, and set up a model of dynamic O-D flows estimation for freeway corridors. The paper also designed a genetic algorithm to solve the problem, discussed six key issues of the algorithm, and provided an effective method to obtain the dynamic O-D flows between entry and exit of freeway corridors. Data experiments and practical application show that the model and algorithm are efficient and accurate, and can be applied in on-line systems.

In wireless networks, due to temporary link outages or fading-induced bit errors, the packet loss cannot mean the congestion occurring in the network. Therefore, explicitly notifying the congestion can be an important measurement to solve congestion. ECN is one of the explicitly notifying mechanisms advocated by the Internet engineering task force (IETF). In this paper, we modify ECN mechanism so that it can provide more information for end hosts to share the bandwidth. We call the new mechanism as ECN2 that allows end hosts to more efficiently utilize resources, and ECN2 feedback information as triple feedback since it can give three different states of the link. To meet ECN2, we propose an enhanced AIMD mechanism, which can keep more stable, more robust and more prompt data transmission. We analyze the stabilization of the new enhanced AIMD mechanism by using differential equations.
