Authors: Ma Ru Hui , Liu Yuan
Published: January 2010

Neural network (NN) employed to settle network anomaly has become prevalent. However, traditional training algorithm for NN is not optimum, that is, often suboptimum, and encountering complicated network anomaly, an adaptive yet efficient NN or hybrid NN model should be better considered. Therefore, this paper proposes a novel network anomaly detection method employing wavelet fuzzy neural network (WFNN) to use modified Quantum-Behaved Particle Swarm Optimization (QPSO). In this paper, wavelet transform is applied to extract fault characteristics from the anomaly state. Fuzzy theory and neural network are employed to fuzzify the extracted information. Wavelet is then integrated with fuzzy neural network to form the wavelet fuzzy neural network (WFNN). The Quantum-Behaved Particle Swarm Optimization, which outperforms other optimization algorithm considerably on its simple architecture and fast convergence, has previously applied to solve optimum problem. However, the QPSO also has its own shortcomings. So, there exists a modified QPSO which is used to train WFNN in this paper. Experimental result on KDD99 intrusion detection datasets shows that this WFNN using the novel training algorithm has high detection rate while maintaining a low false positive rate.

Published: January 2010

Job-shop is the problem of allocating the tasks to machine tools with a time table satisfying a set of objectives. Currently researches on Job-shop generally take the independent production processing as the study case. It is still difficult to schedule the production processing with complex correlated features. Taking the shop with m machine tools and n waiting correlated tasks as the study case, this research proposes an evolutionary algorithm-based and correlated constraint-driven optimization method to overcome the above difficulty. First, the tasks are classed as the correlated tasks and independent tasks according to the correlated features and the priority levels, which construct the foundation of modeling for complex correlated constraints. And then, the objective function is built taking the lower production cost and higher equipment capacity factor as optimization objectives. Finally, the optimization model is developed and solved with the specialized evolution algorithm. The simulation with the Matlab demonstrates the feasibility of the novel methodology.

Authors: An Xue Li , Jiang Dong Xiang , Zhao Ming Hao , Liu Chao
Published: January 2010

A model for the coupled lateral and torsional vibrations of a vertical unbalanced rotor is developed. The equation of motion is obtained using Lagrangian dynamics without considering the external actuating forces and torque. The equation showed coupling and nonlinear interaction between the rotor lateral and torsional vibrations. Most of the earlier work on coupled vibrations has been done for the horizontal rotor model. The coupled vibrations for a vertical rotor have not been reported in the past. An attempt is made to reveal dynamic characteristics of vertical rotor. The results of the simulation showed the coupled between torsional and lateral vibrations is induced by mass eccentricity. Coupled vibrations have appeared in the start period of the vibration. After a transient vibration process, the vibrations are not coupling. The lateral vibration becomes equal amplitude with shafting speed. And the torsional vibration keeps on attenuating until it stops. When the vibration is coupled, the coupling effect on which torsional vibration to lateral vibration is evident. But there’s no coupling effect on the lateral to the torsional. It is also shown that for some operational parameters, the controlling action may excite large lateral vibrations due to coupling with the torsional motion.

Equivalent Time Sampling is a popular sampling method which usually used in oscilloscope technology. When input signals have the similar features as the jump signal, whose information focus in a very short period of time, the Equivalent Time Sampling’s disadvantage will become more obvious. This paper proposed a new sampling method named Vertical Sampling based on testing time via ADC. High-speed voltage comparator, ADC, and mathematical model between phase and time are used in this method. The whole system obtains unknown input signal’s tendency information and the time difference information to accomplish the sampling process.

But the signcryption sender can cheat in the protocol with forged information for lack of supervision by public verification. Then we presented an improved signcryption scheme with public verifiability, in the scheme signcryption message is generated with private key of message sender and other public parameters, any trustable third party can verify the signcryption without disclosing private key or secret parameters. Besides, the attack on the signcryption and secret parameters via public verification data is computationally infeasible. The scheme reinforces the security and reliability of signcryption and effectively improves its efficiency for engineering application.

Published: January 2010

This study deals with how to retrieve images using a rearranged chain-code based column vector. The chain-code expresses objects or boundaries of areas in straight chains with fixed direction and length, and encodes the final boundary, which is sensitive to rotated images. This study, therefore, works with chain-codes of eight directions in images and uses differences between values of chain-codes to obtain newly-rearranged chain-codes for image retrieval.

As any linear antennas can be considered to be comprised of a large number of dipole antenna, therefore the study of dipole antenna characteristics has a very important significance to the application of the general linear antennas. In this paper, Firstly, the radiation field of the dipole antenna is analyzed, and then the radiation field mathematic model of a specific structural antenna is established. The antenna is composed of two orthogonal half-wavelength dipoles, and the current phase of one dipole is advanced the other by 90°. According to the polarization theory of electromagnetic wave, the polarization of this antenna is discussed. The antenna pattern mathematical formula is deduced in horizontal and perpendicular plane, and the antenna pattern is given in graphics. Finally, a new method is introduced that the directivity of horizontal polarization component can be enhanced by increasing the number of antenna elements in the vertical plane, the simulation result show that this method not only enhance the energy of horizontal direction, but also restrain the radiation of other direction.

Published: January 2010

The increasing use of wireless communications in mobile devices starts a new level of resource management. Users with mobile devices accessing wireless hot spots are a commonplace, and, thus, their management is becoming more important. Therefore, efficient utilization of radio resource becomes a key point in the design of broadband systems. From the view of the development of radio resource management, current technologies have quite good performance and high efficiency when the category of service is single. However, when multiple services take place simultaneously, the system has to emphasize on some certain kinds of services and degrade the performance of others. Moreover, the wireless network is not able to detect collision and monitor the channel status as is the wire line network, which makes it more difficult to design the management scheme. This paper introduces and analyzes current main technologies of radio resource management, discusses the key technical points on designing the scheme, and then offers a new proposal of uplink radio resource allocation scheme in broadband systems. Based on the detailed illustration of the algorithm, a simulation system is established to verify it, which is adapted to the typical situation of broadband wireless communication systems. The theory analysis and the simulation results show that the new method successfully resolves the uplink bandwidth allocation problem for the simultaneous multiple services, satisfies the different requirements of delay and bandwidth of different services, and also reduces the protocol wasting and transmission delay.
