A displacement sensing system with the prototype of magnetic-grating-like hydraulic cylinder is developed. It consists of a signal acquisition module, a signal conditioning module, a signal processing module, a signal isolation module and an electrical stimulator module. The system realizes signal processing with the application of tangent segmentation principle. Tests of this devised system have...
Due to the approximate design method itself, and the impedance matching material parameters, and requirements of dielectric materials to be kept intact, etc, the scattering effect is produced when the elastic wave spreads in the design of material with the transformation method. The result of design focuser homogeneous elastic wave approximation as the research object, fractional Fourier transform...
Fault diagnosis provides reliable and fast information of working elements under working condition, and an SVM-based sensor failure recognition module of solenoid valve neutral function identification will allow users to effectively determine the fault mode. The setup of sensor fault recognition system is proposed, which designs a methodology consisting of three parts, namely the hardware layer, middleware...
The movement to e-government, at its heart, is changing the way people and businesses interact with government. E-Government offers a huge potential in seeking innovative way to reach the ideal of government of people, by people and for people. This paper will introduce what is e-government, the goals, benefits and the risks of e-government.
In the proposed method, a pavement image is converted to a grey-scale image which is decomposed by using contourlet transform. Then directionality and anisotropy are used to enhance the singular characteristic of the image by expanding all scale detail coefficients to the same size and combining the coefficients. The approach avoids unreasonable evaluation result of classical unified crack index pavement...
The rise of 'e-government', both as a recognized field of practice and an identifiable and legitimate field of study, has occurred extraordinarily rapidly throughout the world. The term 'e-government' has come to capture and de-limit into what might be termed the agenda for government in the age of the Internet. This article questions the value of the orthodox interpretation, the paradigm that has...
Aim at the drawback of original chrome-plated system and the demand of modified control system, while retaining the original manual control mode, in this paper, SIMENS configuration software WinCC and S7-300 series PLC as well as the original system's automatic equipment are proposed to compose the DCS system, having realized the automation of the entire electroplated production process, and at the...
In this paper, a novel control scheme of the application of PWM method in the rectifier power source control is proposed. The proposed method is to control the rise, or fall in current and some switch signals, which are affected by the varying load. Although the PWM is used broadly, the method how to determine the PWM pulse width in the rectifier galvanization production line is seldom to be concerned...
