The magnetic anomaly created by ferromagnetic ships may endanger their invisibility. Nowadays, a new technique called closed-loop degaussing system can reduce the magnetic anomaly especially permanent one in real-time. To achieve it, a model able to predict off-board magnetic field from onboard measurements is required. Many researchers settle the problem by some numerical models. In this paper, we...
Pressure sensing technology is used to pressure environment monitoring in agriculture, a basic pressure sensing system is designed. The pressure signal acquisited by pressure sensor in agricultural environment is converted into sensor amplified output voltage, and then changed into pressure digital signal by A/D converter. Finally the agricultural pressure data manipulated and analyzed by SCM program...
The contradiction between industrialization and the environmental protection as well as the energy saving has become the main restriction to the economic development of many countries in the world. In order to achieve the goal of sustainable development, it is a crucial strategy to greatly promote the actions about energy saving and emission reduction in coal-fired power plants. This paper just focuses...
