Cavitation is a common harmful phenomenon in hydraulic transmission systems. It not only damages flow continuity and reduces medium physical performance, but also induces vibration and noise. At the same time, the efficiency of a system is reduced due to cavitation, especially dynamic performance are deteriorated. Applying commercial CFD software FLUENT, the cavitation issuing from the orifice was numerically investigated, reducing the harm. The effect of liquid parameters (such as surface tension, gas content, and the temperature) on the oscillation of bubble is studied numerically. The modified Rayleigh-Plesset equations are presented to describe the oscillation of bubble in different liquids. Employing the finite difference calculus, the behavior of a cavitation bubble in liquids with different physics parameters are obtained. Meanwhile, the numerical results are compared with experiment results. It is observed that the viscous force decreases the growth and collapse of a bubble, making it expand or collapse less violently. And the surface-tension forces stave bubble growth progress and speed up bubble collapse process. On the other hand, both the maximum bubble radius and bubble lifetime increase with increasing temperature. These results can provide theory basis for understanding cavitation bubble dynamics in the hydraulic systems. © (2014) Trans Tech Publications, Switzerland.

This paper deals with the problem of fault estimat ion for satellite attitude control system with typical component configuration. In order to understand sensor and actuator faults propagation in the attitude control system, we have built the overall system model firstly, which includes the attitude dynamics model, sensor measurement model, attitude determination model, controller model and the moment distribution model. The faults are then considered as unknown inputs and are estimated using a classical proportional-integral observer, more over constant or time -varying fault can be estimated. The proposed observer is derived as a solution of off-line Linear Matrix Inequality (LMI ) conditions. Additionally, simulation results are presented to illustrate the efficiency of the proposed method. © IFAC.

In this work, we have studied the optimal spectrum sensing interval, which is the time between two consecutive spectrum sensing activities, such that the delay of the cognitive transmission is minimized. The throughput maximization of the cognitive radio is always a common goal of the researchers, which is keenly related to the delay of the cognitive transmission. Whereas the delay is mostly decided by the spectrum sensing interval for a given primary user (PU) channel. Therefore, we have studied the setting of the spectrum sensing interval to minimize the transmission delay of the secondary user (SU). Especially, the retransmission is considered, which deteriorates the delay of the cognitive transmission;however, neglected by the most studies. Finally, we provide both the optimal setting of the spectrum sensing interval and the numerical values. © (2013) Trans Tech Publications, Switzerland.

In this paper, we propose the amplitude modulation (AM) bandwidth and the frequency modulation (FM) bandwidth for far-field point target model and near-field multi-point target model, and analyze the statistical differences of their distributions. The result shows that there exists a significance difference between the distribution of AM (resp. FM) bandwidth under the model of ideal far-field point-target and near-field multi-point target. The two bandwidths, namely AM bandwidth and FM bandwidth, have been used as an input to support vector machine (SVM) for classifying far-field deceptive jamming signal and the near-field body target signal. The simulation results show the effectiveness of the proposed method for classification.

This paper proposes a novel method utilizing chirp signals to substitute the traditional ultra-wideband (UWB) pulse waveform. With the application of the effective iterative method and the development of spectrum detection technology, the Conjugate Gradient (CG) algorithm and Cognitive Radio (CR) technology are employed to realize the adaptive filter and narrow-band interference (NBI) suppression. Utilizing the characteristics of the CG algorithm and its corresponding adaptive filter, we realize the NBI suppression and obtain the low cost and more practical UWB pulse design for a kind of optional proposes. Simulation results show that the CG adaptive filter can suppress the NBI effectively and outperforms the conventional method significantly.
