Flight control system plays an important role in the process of missile designing. The quality of flight control system will affect the missile's performance significantly. In this article, we design a flight control system using variable structure control theory. Firstly, we establish a mathematical model of the missile and the basic content of variable structure control theory is introduced. Next...
Disasters, such as earthquake, tsunami, tornado, and malicious attack, may cause large-area, geographically correlated and/or cascading failures in telecom networks, leading to massive connection disruptions and instability of network state. In this paper, we study survivability strategies to alleviate the effect of disasters to telecom networks, e.g., Wavelength-Division-Multiplexing (WDM) optical...
A vehicle detection algorithm based on three-frame differencing and background subtraction is presented in this paper. Firstly, improved GMM is for background subtraction, then the moving object region is gained using background subtraction, and then the background subtraction is combined with three-frame differencing to detect the motion information. the simulation results show that the proposed...
Characteristic impedances of regenerator and heat exchanger in thermoacoustic engine are analyzed by network model. The effects of regenerator geometry on characteristic impedance of regenerator are studied. The characteristic impedances of regenerator and heat exchanger which have same structure are calculated, the result indicated that the absolute value of the characteristic impedance of regenerator...
This article describes the network analysis of design and calculation for thermoacoustic engine. Thermoacoustic network model was built for a new traveling wave thermoacoustic engine with external excitation by analyzing of active and passive thermoacoustic network model for a variety of the thermoacoustic components. So it laid the foundation for design and theoretical arithmetic of thermoacoustic...
