This paper is aimed to explore the equivalent circuit models of piezoelectric ceramics with the consideration of energy dissipation. Based on the electrical impedance, the equivalent circuit models of piezoelectric ceramics are investigated under unloaded and loaded conditions. The characteristics and physical meanings of the circuit models are discussed by considering the frequency range of interest. The circuit models and discussions in this paper can provide a good understanding on the electrical behaviors of the piezoelectric ceramics when designing and analyzing the piezo-based systems.

A novel orientation tracking algorithm is introduced. The algorithm can provide 3DOF orientation information of an object in a hemisphere space. It is based on two-dimensional information about the gravity field and the earth magnetic field. Comparing with the traditional algorithm, it reduced the needed information from three dimensions to two dimensions in operation. It is faster and simpler. The algorithm is validated with a system. The results indicate the algorithm can track the orientation of the object well.

In the medical field and in biotechnology, a new type of micropump that can supply micro liquid flow has urgently been demanded. It is our purpose to develop a type of micropump that has the characteristics of flexibility, driven by a low voltage, good response and safety in body. In this paper, we propose a new prototype model of a micropump using SMA (shape memory alloy) coil actuator as the servo actuator. This paper describes the new structure and the motion mechanism of a micropump using SMA actuator and discusses the possibility of the micropump. This micropump consists of two diffusers (inlet) as one-way valve, a pump chamber made of elastic tube, and a casing. The overall size of this micropump prototype is 16mm in diameter and 74mm in length. Characteristic of the micropump is measured. The experimental results indicate that the micropump has the satisfactory responses, and the proposed micropump is able to make a micro flow and is suitable for the use in medical applications and in biotechnology.

This paper presents the genetic-neural network for sinter's burning through point since BTP control is the most important, which is tightly coupled with sinter ore quality. In offline, advanced genetic algorithm (GA) is used to optimize the original connection weights and thresholds, and during online, hybrid neural network (HNN) inherited from the principle of backpropagation is used to train the map parameters and improve the system precision in each sampling period. The results obtained from the actual process demonstrate that the performance and capability of the proposed system are superior.

Flocculating river water and adding CLO/sub 2/ into the inlet and outlet of the cooling water system can effectively raise water quality, lower turbidity, eliminate alga microorganisms in the cooling water and reach the standard of the cooling water for power plants. In the paper, the effects of flocculation and algae removal in the cooling water treatment are studied. In order to get to the optimum treatment effect, the paper puts forward a computer Web monitoring system based on PLC and discusses the system organization, the software and hardware structure and the Web communication model. The realization of the computer monitoring system increases the efficiency and effect of the cooling water treatment.

In this paper, a kind of fuzzy neural network based on hybrid genetic algorithms is proposed. Hybrid genetic algorithm is presented to train the fuzzy neural network. The hybrid genetic algorithm improved normal genetic algorithm. The BP algorithm is added to genetic algorithm. In particularly, the global convergent characteristic of the genetic algorithm is used to find the possible universal optimum, and the great feature of the BP algorithm, that is, error descend in the direction of grads, is used to fast search about the optimum. Thus, the fast learning capability and an accurate approximation ability are obtained. The fuzzy neural network is used to the control problem of truck backer-upper. The simulation results show that it achieves better control effect.
