In-situ stress is the basis for designing mine roadway supports. Firstly, based on GA-BP algorithm, establish a numerical analysis model, apply orthogonal tests, to relationships between in-situ and lateral pressure coefficient, different rock parameters. Then, optimization model built by setting sum of squares difference measured calculated stresses as targets. Finally, using solve stress. Res...

A hybrid algorithm of the BP-ANN/GA (Back Propagation Artificial Neural Network and Genetic Algorithm) is developed to optimize the initial weights and make fast convergence of the BP-ANN. This algorithm is applied to data fusion of Landsat ETM+ and ERS-2 SAR for classification of the urban terrain surfaces. An example of the Shanghai Pudong area using both the Landsat ETM+ and ERS-2 SAR image ...

Abstract In order to reduce the interference of ambient light on near-infrared blood oxygen sensors (used measure saturation human tissue or circulating during Extracorporeal membrane oxygenation treatment) and improve measurement accuracy a sensor, compensation method is proposed. This does not need an sensor additional circuit. The intensity calculated by changing value emitted LED in combini...

Bioretention systems are an important measure in sandy city construction to remove pollutants. This study collected all the operating data samples of bioretention ponds currently operation China and used Mantel test Redundancy Analysis (RDA) optimize main factors that affect changes pollutant-removal efficiency. Genetic Algorithms (GA) were Back Propagation (BP) neural network model, a predicti...

Short term load forecasting is very essential to the operation of electricity companies. It enhances the energy-efficient and reliable operation of power system. Artificial neural networks have long been proven as a very accurate non-linear mapper. ANN based STLF models generally use Back propagation algorithm which does not converge optimally & requires much longer time for training, which mak...
