We estimate the decay rate of the Ψ(2S) to J/Ψ(1S) + 2 π and J/Ψ(1S) + σ + 2 π. This is based on the mixed hybrid theory that was developed for the Ψ(2S) and was used to estimate the ratio Ψ ( 2 S ) → J / Ψ ( 1 S ) + σ ${\Psi }(2S)\rightarrow J/{\Psi }(1S) + \sigma $ to Ψ ( 2 S ) → J / Ψ ( 1 S ) + 2 π ${\Psi }(2S) \rightarrow J/{\Psi }(1S) + 2 \pi $ in 2011. A main motivation of...
Aiming at great positioning error and “invagination” of boundary region by the method of weighted centroid algorithm, it is proposed in this paper that the algorithm named estimate based on virtual-derived points (EVD) would be applicable. By the method of analogous projection of unknown node, we can obtain the virtual-derived point in monitoring area, then we can treated the practical value of virtual-derived...
Shearer height adjusting is a key technology for coalmine unmanned working face. On the basis of establishing Shearer working face mathematical models, this paper determined related parameters influencing the Shearer height adjusting, then analyzed traditional Shearer memory cutting strategy and pointed out its shortcomings. Aiming at changing technical limitations of Shearer height adjusting currently,...
The approximation accuracy of RBF network constructed by the incremental learning algorithm to the target was not high. For function approximation or other requirements of high accuracy, such accuracy of RBF network model can not meet the requirements. We have improved this network model focused on three aspects to improve the bottleneck, and have an experiment and comparatively analyze these improvements...
