COMMUNICATION BY ELECTRICAL STIMULATION OF THE SKIN. J. ABSOLUTE IDENTIFICATION OF STIMULUS INTENSITY LEVEL fo determine the number of possible absolute identification» of t intensity levels in order to evaluate the usefulness of intensity e in an electrical cutaneous communication system. Intensity levels presented wore equally spaced in term« of apparent magnitude of sensation within the rang...

This paper analyses the factors affecting heating consumption of a substation. The input parameters neural network prediction model are analysed and selected. average absolute error, percentage mean square error used to evaluate effect model. results show that when maximum outdoor temperature, temperature difference between primary supply return domestic hot water, load in previous three days, ...

Because of the defects of a posteriori and experience-depended traditional method, a prediction model of the length of garment marking based on dynamic fuzzy neural network (DFNN) combined with Quantum-behaved Particle Swarm Optimization (QPSO) was proposed. The salient characteristics of the method are: 1) hierarchical on-line selforganizing learning is used; 2) neurons can be recruited or del...

Recently most of integrated circuit chips are made from monolithic IC, which can be manufactured at low cost. In monolithic IC, absolute error which is proportion of the difference of actual value to the designed value of each element is large (several tens of percentages), but the maximum difference of the absolute error of devices on a chip, is small (a few percentages). So it is suitable to ...

PURPOSE To design a simple and reproducible method with minimum uncertainty for evaluating the stereotactic accuracy of Computed Tomography imaging and Magnetic Reso-nance Imaging and to compare the results. METHODS 3D phantom has been designed with 1 mm diameter targets in eight sectors for stereotactic MR imaging and CT imaging. The phantom was connected to Leksell stereotactic frame and th...
