In view of the problem that traditional electric power prosperity index lacks support mixed frequency and multi-dimension data, a new consistency measure method is constructed, which uses time difference correlation analysis principal component consider linkage economy at same time. Take Hunan province for example, we set pool kinds sectional electricity consumption other relatives use to captu...

Let $G$ be a $t$-uniform hypergraph, and let $c(G)$ denote the cyclic index of adjacency tensor $G$. $m,s,t$ positive integers such that $t \ge 2$, $s 2$ $m=st$. The generalized power $G^{m,s}$ is obtained from by blowing up each vertex into an $s$-set preserving relation. It was conjectured $c(G^{m,s})=s \cdot c(G)$. In this paper we show conjecture false giving counterexample, give some suffi...

A switching mode power supply (SMPS) is a hopeful candidate for the 1MW CW klystron power supply of KOMAC (KOrea Multi-purpose Accelerator Complex). The merits of the SMPS are low stored energy, small size, high rating efficiency and possible cost saving whereas the demerits are EMI problem and system complexities. The proposed power is 2MW and it is considered that the modules, each of which h...

Voltage collapse and blackout can occur in an electric power system when load powers vary so that the system loses stability in a saddle node bifurcation. We propose new iterative and direct methods to compute load powers a t which bifurcation occurs and which are locally closest to the current operating load powers. The distance in load power parameter space to this locally closest bifurcation...

We characterize the alpha power and chirped types of refractive index profile planar slab waveguide in terms of TE/TM mode study, waveguide dispersion study, mode profile properties, power confinement factor and universal b-V graph. Our own developed finite element method has been efficiently applied to analyze the symmetric planar slab waveguide having a complicated refractive index profile. T...
