A detecting way based on Android platform was proposed in order to detect greenhouse tomato disease degree in real time. This way employed the camera in mobile phone to acquire tomato disease leaf image in the greenhouse. Firstly, the detection system was built by the Eclipse based on the Android development environment. The iterative threshold segmentation algorithm was used to separate the tomato...
In practical chemical plants, melt index (MI) can only be measured by off-line analysis which cost 2–4 hours. So it is important to develop online analyzers using process data especially when the mechanism is complex. A novel data based soft-sensing method is proposed for MI estimating in propylene polymerization process. This approach is constructed under just-in-time modeling scheme, in which historical...
On the basis of traditional data envelopment analysis model, by introducing the ideal decision making unit, the improved data envelopment analysis model is established to determine a set of common weights; then according to them , efficiency index of each black start plan is calculated to rank the black start plans. Finally, it is verified that this method is effective and advantageous through the...
To achieve the product green design, from the view point of disassembly after the product retirement, the article studies disassembly sequence of products and indexes related to disassembly process respectively and makes a comprehensive evaluation. And on the basis, it puts forward reasonable and feasible measures. Finally it combines examples to verify the methods.
