This paper studied the basic principle and realization method of Curvelet transform on the basis of analysis Ridgelet transform. Wavelet transform is more applicable in processing point singular signal, however, it is obviously insufficient in the analysis of the image edge feature of the curve of two-dimensional image or a straight, while the Curvelet transform has more directional and has better...
PID controller can not perform well in liquid level control system because liquid system has characteristics of time-delay and inertia. Based on the characteristics of two-tank liquid control system, an ADRC is designed by using control technique of active disturbance rejection. In order to study the control performance of ADRC, the comparative analysis with PID controller is to be carried out in...
Microcomputer relay protection hardware system reliability design is directly related to power system safe and stable operation. Aiming at the mistake switch and misinformation resulted from electromagnetism interference of microcomputer relay protection system based on the fourth age's high performance microprocessor, the paper presented improving design concept of anti-electromagnetic interference...
With the construction of harmonious society, health improvement and the rapid development of information technology, People put forward higher requirements for the hospital. Hospital information system as an online services system requires continuous operation. Server system is the key to support hospital operations. System paralyzed accident caused by Server system failure is also not uncommon. Aiming...
Aiming at many monitoring systems focusing on real-time monitoring and so being difficult to more directly and conveniently understand the software performance issues by the historical data analysis and remote monitoring, this paper presents a server performance monitoring system program based on B/S mode. The program is divided into two main functional modules: the monitoring of current use of resources...
As the expansion of the standard Support Vector Machine, compared with the traditional standard Support Vector Machine, the Least Squares Support Vector Machine loses the sparseness of standard Support Vector Machine, which would affect the efficiency of the second study. Aimed at the above puzzle, the article proposed an improved Least Squares Support Vector Machine incremental learning method, using...
The temperature control system of electric heater is a complex system. It has several characters such as nonlinear, parameter time variation, lots of control variables, controlled variables delay, etc. There exists interference caused by many uncertain factors. The traditional fuzzy controller can hardly ensure that the system controlling effect kept in ideal state all the time. Aimed at existent...
The paper discussed a new image segmentation algorithm that based on fuzzy mathematical morphology, aiming at the noise and exiguity catchment basin of image that result in over-segmentation phenomenon when adopt traditional watershed algorithm to segment an image. The method adopted firstly opening-closing algorithm based on fuzzy mathematical morphology to smooth the image and then to compute its...
Aimed at the information isolated island resulted from traditional data process technology, it was difficult to integrate various heterogeneous systems and applications, the paper proposed a sort of intelligent monitoring system based on embedded Web. The paper took the monitoring system of forecourt devices in gas stations for oil products retail network as an example to explore the realization of...
Web intelligence has been widely used in industrial automation system, this paper presented a sort of integrated control scheme based on embedded Web intelligence that aimed at the existent problems such as distributing of gas stations being wide in China, communication protocol of dispenser being disunion, being difficult to realize integrated control and so on. The intelligent computer MOXA7420/7410...
