Acupuncture is effective to treat various diseases. However, the underlying regulation mechanisms of acupuncture remain unclear. In this paper, repeated-pulse magnetic stimulation was used to stimulate the left Hegu (LI4) point of healthy people. EEG signals were recorded before and during magnetic stimulation. Based on the theory of complex network analysis, functional networks under multi thresholds...
Handwritten character recognition is a kind of technology that recognizes the handwritten symbols automatically. Aim at the complexity and limitations of the traditional handwritten character recognition method, a NGA-BP model for character recognition which combines the niche genetic algorithm and neural network is built. This method makes great use of the searching ability of ecological niche genetic...
In view of the current situation of the less embedded Linux image acquisition application based on V4L2(Video for Linux Two), embedded image acquisition system based on V4L2 is designed. S3C6410 is adopted as hardware development platform and Linux as software platform. After loading the driver of CMOS camera OV9650 and other relative drivers, image acquisition applications on the basis of V4L2 is...
By combining two groups of three-phase power lines, a modeling that can induce power frequency electromagnetic fields has been presented. Charge simulation method and Biot-Savart law have respectively been adopted to compute the three-dimensional electric and magnetic fields in exposed environment of the modeling. Simulations indicate that the intensity of electric field can reach up to 5kil-volt...
