High speed and accurate extraction of light spot center coordinate is very important for an optical detection system. A center-extracted method based on FPGA by combining the Kalman filter with the Hessian matrix is proposed for the implementation of real-time light spot processing. The proposed method reduces the searching area and the number of Gaussian convolutions greatly, and improves the speed...
As reverse logistics is developing rapidly in China, it is very difficult for enterprises to deal with the stochastic vehicle routing problem with simultaneous delivery and pick-up. In order to solve this problem, a mixed integer programming model for this problem is constructed in this paper. Then, an Ant Colony System algorithm combining with route simulation method and local search is proposed...
In truss structure with fuzzy parameters of the random seismic analysis, the expression for the fuzzy numbers is through the decomposition theorem of fuzzy sets or extension principle to fuzzy-valued functions transplanted up, and this analysis's method causes the very major difficulty for the fuzzy number research work. This method of using information entropy makes the fuzzy structure into a random...
Traditional approach for product family forming is based cell manufacturing system and design/product structure oriented. In this paper, an innovative methodology for product family forming is presented to effectively cope with customized demand. The methodology is designed under product-family specific production line (PFPL) environment and the criteria for product family forming are based on manufacturing...
This paper presents a model for analyzing the impact of private information on behaviors of supply chain members under the manufacturer-Stackelberg setting. The model consider a distribution system in which a manufacturer supplies a single product to a retailer, who faces a current-stock-level-dependent demand. This paper focuses on two aspects. First, under common information, we briefly discuss...
A balanced frequency doubler has been demonstrated in 0.25-μm SOI SiGe BiCMOS technology operating from 22GHz to 29GHz with high fundamental frequency suppression and high conversion gain. A LC resonator circuit is designed to improve the suppression and conversion gain. The measured fundamental frequency suppression of greater than 45dBc is achieved at an input power of -9dBm in the 22-29GHz. Moreover,...
The present paper presents the support vector machine (SVM) based semi-active control algorithm with a view to general dampers for multistory structures under earthquakes. Firstly, the LQR controller for the numerical model of a multistory structure formulated using the dynamic dense method is obtained by use of the classic LQR control theory. Then, a SVM model is designed and trained to emulate the...
In this paper, by using the various types of Lyapunov functionals and the property of Lyapunov matrix equation as well as the property of Riccati matrix equation, criteria are established for decentralized stabilization of multidelay stochastic large scale systems using local state feedback. The stability of the closed-loop stochastic large scale systems is independent of delay and robust for the...
