The correlation among wind velocity, light intensity and load is not considered in generation capacity configuration in microgrid. This paper proposes a combined sampling method which can consider the correlation based on Copula theory. It analyzes the law of data, then chooses the best Copula function of every segment to sample and combines all sampling result together. A mathematical model of capacity...
A simplified simulation approach has been introduced for gated field emitters. F-N equation fitted with experimental field emission characteristic is used to calculate the characteristics of a double-gated field emitters. By assuming the cathode is a flat thin film, the anode current and gate current are simulated. The validity of the simulation is evaluated by experimental results.
A modified on-surface discretized boundary equation (OS-DBE) method is proposed for solving scattering problems of conducting cylinders with electrically large concave parts. It utilizes the original OS-DBE to determine the surface current density on the convex part point by point, while obtains the current distribution for the concave area by the OS-DBE in only one operation. Numerical results are...
The application of the method of moments usually requires a minimum degree of differentiability for basis and testing functions. Through the solution of the electric field integral equation (EFIE) for scattering by a perfect conducting cylinder illuminated by a TE wave, however, it is shown that such a restriction can be loosed. Theoretically, pulse basis functions and point matching are usually considered...
Tracking historical levels as well as estimating future levels of patent applications is an ongoing activity of considerable significance. The patent applications filings (PAF) are complex to conduct due to its nonlinearity of influenced factors. Support vector machines (SVM) have been successfully employed to solve nonlinear regression and time series problems. Grey theory is a truly multidisciplinary...
