Sugarcane is one of the most important economic crops in south China. It's of practical value to quickly assess the leaf area index (LAI) of sugarcane and evaluate its growing state. Field-based or in situ measurements are very labor intensive and time consuming, while satellite images are relatively coarse and unsuitable for real-time crop monitoring, not to mention the cloud-prone climate in south...
The dynamic laser antimissile problem is focused on with the very fast simulated annealing (VFSA) algorithm. The attacking ordering optimization plays an important role in the real-time application. This problem is much harder than the traveling salesman problem. There are many barriers for finding the global optimal solution, especially when the number of the targets is greater than six. The very...
In order to evaluate the safety suitability of site for city lifeline, evaluation model is constructed on the basis of artificial neural network (ANN). According to double parallel feed-forward neural network model, which is a basic model of Back Propagation (BP) network, evaluation model and calculating method are analyzed. The model is applied to site stability and suitability evaluation of underground...
Based on the substance of university science research capability (USRC) and the highly self-organized, self-adapted and self-learned characteristics of back propagation (BP) neural network, the paper conducts a research on evaluation of USRC, in which an evaluation index system of USRC is constructed and a 15-7-1-typed BP neural network with three layers is presented to evaluate USRC, which provides...
