The registration of EEG electrodes with a head model is the initial step for advanced EEG data analysis such as inverse problem solution and various high-resolution mapping. This paper presents a real-time system for registering the point set of EEG electrodes to head model reconstructed from an anatomic MRI. In this system, a friendly interface is designed for user to select the desired reference...
Three-dimensional medical image reconstruction for both transmission and emission tomography has traditionally decomposed the problem into a set of two-dimensional reconstructions on parallel transverse sections. An approach for reconstructing tomographic images based on the idea of continuous dynamical methods is presented. The method consists of a continuous-time image reconstruction (CIR) system...
System of coal mine emergency plans (EP) is effective means to prevent coal mine accidents and disasters accidents, and also is one important segment to establish perfect coal mine safety production system. According to emergency management situation of coal enterprises, the meta framework model of emergency plans are established for emergency plans organization and navigation. On this basis, the...
Based on the theory of system engineering, coal mine production safety has been analyzed. From workers, production process, coal production and economy, coal mine production safety evaluation indexes have been confirmed, and then the BP neural network model of coal mine production safety evaluation has been built. After training and testing the model, the model can accurately evaluate the coal mine...
According to international standards of hot-melt pipe welding and requirement that the amplitude fluctuation of output tunable voltage should be less than plusmn 0.5 V, a high performance hot-melt pipe welding control system was developed. Single chip microcomputer 89C51RD2 was the control core of the system. It analyzed the working principles of hot-melt welding system that by using interruption...
