The fault rate of offshore wind turbines is so high that it is necessary to build a reliable condition monitoring system to improve the maintenance efficiency. To adapt to the harsh operating environment of offshore wind turbine, the condition monitoring system should have good self-healing ability. In this paper, the condition monitoring system of offshore wind turbine is built based on wireless...
The winter in 2009 to the spring in 2010 is hundred years encounter drought period of Yunnan Province. MODIS remote sensing data was used in 2010 and 2012 to compare the four methods which one is suitable in Yunnan Province. Then monitoring drought situation in Yunnan Province by four methods: Vegetation Condition Index (VCI), The Temperature Vegetation Index (TVDI), Cloud Parameters Method, and the...
In order to improve the accuracy and speed of on-line tool wear monitoring system, an evolutionary neural network using variable string genetic algorithm (VGA) was developed to construct the relations between tool wear and signal features extracted from cutting forces, vibrations, and acoustic emission by different signal processing methods. The system could automatically evolve the appropriate architecture...
Terra/MODIS has spectral and spatial resolution advantage over NOAA/AVHRR. To probe into using MODIS near-infrared spectrum further, winter wheat yield estimation was taken as example in Hebei Province, China. Firstly, according to winter wheat biological characteristic, three MODIS near-infrared spectrum data were retrieved in heading stage, which central wavelength is 860 nm, 1240 nm and 1640 nm...
