This paper introduces new methods for sensor fusion in homogenous sensor networks in the presence of the communication time delay. It allows the sensor nodes to solve consensus problems despite the network induced delay. It is shown that such approaches guarantee tracking of each consensus filter output to the original value of the measured signal in both regular and non-regular network graph topology. In the non-regular case, there is a sufficient condition to prove the convergence. In the networks with communication time delay, consensus problem is solved by considering time delay as a constant as well as using the idea of the variable sampling period in order for time delay compensation. In the second case, each sensor sampling period is variable and it is taken as maximum predicted time delay of the all channels in the network at each sampling period. In this way, an MLP neural network is used for time delay prediction and a majority consensus filter is introduced for approximating maximum predicted time delay in the network. Simulation results are provided that demonstrate the effectiveness of these methods for distributed sensor fusion and solving consensus problem in the presence of the time delay.

An improved probabilistic data association is proposed to overcome both the drawback of complication in joint probabilistic data association and the unneutrality of multi-targets processing by probabilistic data association. It incorporates the radar Doppler measurement information and modifies weighting of state estimation of measurements in the common region, and then makes the final estimation more exact and improves further performance. The theoretical analysis and Monte-Carlo simulation results show that the algorithm has small computation cost and a better real-time tracking performance.

The purpose of inspection robot for power transmission lines is to check running state and find damages of extra-high voltage (EHV) power transmission lines equipment. The key of the control design is how to design a robot for obstacles navigation. This paper presents the robot configuration, and describes obstacle-navigation control principle. If the horizontal pose of the body is kept through the gripping mechanism, the gripping force will become bigger, and result in the damage of OGWs. So a centroid adjustment method, which enables the centroid of inspection robot to adjust is proposed in this paper. And then paper presents expert system with hybrid architecture and analyzes decision-making of obstacle-navigation in layered planning mode. On-line experiment results show that the control strategy can guide the inspection robot to patrol along the transmission lines and cross obstacles efficiently.

As the traditional ICP algorithm is liable to get local minimization problem, a chaotic BP neural network is presented in the ICP algorithm. In the algorithm, a searching area of real position was plotted centering on the indication of refer navigation system, then terrain altitude data was extracted from refer terrain map. These terrain data, along with corresponding position coordinates, were defined as several patterns and used to train BP network. The network can recognizes certain pattern class with measured water-depth data to determine vehicle's location. However, there are drawbacks of local minimization problem and slow rapidity of convergence in BP network, so improved ways were put forward. The improvement includes replacing common motivating function with chaotic motivating function for and determination of neural network's weights using chaotic search. The experimental results reveal that results of terrain matching can be improved, and matching failure caused by local convergence is overcome to a certain extent.

With the aim to improve the KDD process model and achieve the double bases(database and knowledge base) cooperating mechanism, the paper proposed one RBFCM based maintenance coordinator algorithm, which used RBFCM, a soft computing methodology, representing knowledge and inference in order to maintain in time knowledge base harmonizing with the database. On the one hand, maintenance coordinator algorithm need to keep the knowledge base up with database when three conditions happens, on the other hand, it can automatically solve self contradictions problems existing in knowledge base. Knowledge discovery systems equipped with the maintenance coordinator can evidently enhance the rehabilitation, self cognition and efficiency.

This paper presents two designs on small robotic fish with IPMC actuator. We chose PIC microcontrollers as the control chip for two designs. In the first robotic fish an infrared remote control device is used. We use microcontroller to control DAC and make an OCL circuit as the amplifier circuit. The whole circuit can generate sine wave and square wave. On the basis of the first robotic fish research achievements, the second fish is simplified in the design of control circuit. We use ZigBee remote control module as the communication system. This fish is able to perform the collection of water temperature and display function.

This paper is concerned with H∞ information fusion filtering for discrete-time systems with time-delay sensors based on re-organization of innovation. The key technique applied for deriving the filter is the ro-organized innovation analysis approach in Krein space. The H∞ filter is given in terms of solutions of Riccati matrix differential equations. It is the first time to present the result of H∞ information fusion for linear discrete-time systems with delayed sensors. In the fusion center, It only requires computing scalar weights, so the calculation burden can be reduced. while this method does not requires that the parameters of the system and the statistics of the noises are assumed to be known exactly. Thus the proposed approach is much more computational attractive.

Guided ultrasonic wave is a new non-destructive pipe inspection method for rapid, long distance inspection. It can be used to inspect pipes, especially those buried underground or difficult to access using other conventional NDT methods. In this paper, the excitation frequency of two most commonly used ultrasonic guided waves, longitudinal wave and torsional wave were researched, and the lower and upper frequency limit were discussed in detail. Furthermore, factor that may affect the selection of experimental frequency was studied and optimum frequency of guided wave for a carbon steel experimental pipe was selected.

In recent years, business environment has been perceived to be more turbulent. Manufacturing flexibility (MF) is widely considered as ability aimed at dealing with environment changes; meanwhile, rapid product innovation (RPI) has high priority to get competitive advantage in this kind of environment. They are both related to many important manufacturing decisions. This paper concentrates on analyzing MF, RPI and their relationship to help manufacture managers to make better decisions, so that manufacturing company can create and maintain competitive advantage in turbulent business environment.
