When the field mill is located in complex terrain, such as depression and mountain, the measuring error caused by terrain is always difficult to correct, which will lead the deficiency of observation data about comparability and consistency. Aiming at this problem, this paper conducts a simulation with Maxwell 3D software, thereby discusses the distribution of ground atmospheric electric field on...
The comprehensive archives information digital management system is developed to adapt to the actual archival work in public security service institutions. This article expounds the system from the perspectives of its functions, developing tools, main characteristics and structural designs.
Increasing complexity of software engineering and expansion of scope of application makes software credibility be greatly questioned. How to complete high-quality software production more efficiently is a new software development issue. Data mining has been applied widely in knowledge discovery; data mining technology being used in software development process can not only enhances the accuracy and...
Weigh-in-Motion (WIM) devices are specifically designed to capture and record gross axle load of moving vehicles. Compared with the traditional sensor, cement-based piezoelectric sensor has good compatibility with the concrete. Therefore it's suitable to detect the concrete deformation, damage and distribution of internal stress using cement-based piezoelectric sensor. A novel vehicle WIM system based...
According to the principle of magnetic field oriented vector control, an excitation vector controller of doubly-fed induction generator based on TMS320F2812 of TI Company is designed. With the analysis of the discipline of active power and reactive power decoupling control, the vector control technology to achieve active power and reactive power decoupling control is used, and the variable speed constant...
Traditional security approaches are not sufficient to deal with the protection and survivability of highly distributed information systems operating in unbounded networks. In view of the deficiencies of the essential servicespsila self-recovering when the survivable system is not available, an efficient self-adjusting reconfiguration framework on system survivability is presented based on the service-level...
