The extended equal area criterion (EEAC) is one of the most important methods to identification the stability of Multi-generator Power System, and the key of this method is to correctly identify the critical unit. However, critical units of the existing recognition methods exist some problems, such as...

As the standard object-oriented modeling language, UML describes object-oriented systems from all angles and is object-centric. It is unified with the most popular object-oriented programming languages and can generate code frameworks through class diagrams. There is a corresponding relationship from...

By building remote sensing for monitoring and evaluating water ecological security virtual geographical environment, in general it shows the system framework, integration and coordination models and visualization. It aims to explore for water ecological security and remote monitoring to assess the feasibility...

The external clock synchronization method is difficult to implement, susceptible to interference and insecure for the marine fault recording device, so a synchronous method based on Lagrange once interpolation algorithm is proposed. MATLAB simulation and prototype test show that the synchronization accuracy...

In order to solve the problems of time-varying, nonlinear and large inertia in the pneumatic control system of the intelligent valve positioner, the PID neural network control strategy is used to control the valve opening. Based on the analysis of the principle of the neural network controller, the network...

Groundwater overdraft in Xi'an City is the main cause of the subsidence since 1959. In recent years, ground fissure has been one of the most serious geological hazards in Xi'an, China. This paper aims to research the application of high-precision 3D terrestrial laser scanning techniques (TLS) in land...

In this paper, the new method is proposed for filtering of airborne LiDAR data based on improved Triangulated Irregular Network(TIN) algorithm and the details of filter principle is described. Firstly, LiDAR point cloud data is organized and designed by regular grid and TIN, the seed points from point...

This thesis analyzes the embarrassing situation of uneven development of China's sports TV media in the omni media era, and puts forward the idea that the complementary with new media should be strengthen and local TV media should further cooperate, sports authorities should take effort to improve the...
