In this article,using generalized weighted mean and difference matrix of order m,we introduce the paranormed sequence space l(u,v,p;Δ(m)),which consist of
This talk is concerned with the oscillatory behavior of difference equations correspondingto the second-order nonlinear differential equation x″+ f(x)=t2 =0,wh
Nonlinear dynamical systems are sometimes under the influence of random fluctuations.It is desirable to examine possible bifurcations for stochastic dynamic
Long memory is important in financial modeling.A stationary sequence admitslong memory if its auto-covariance sequence is absolutely summable.If the second mome
Instead of issuing single warrant directly,some firms issue either multiple of call warrants or packages of call warrant and put warrant as a means of debt fina
The understanding of gene-environment interaction is a crucial issue in plant breeding.For this objective,mechanistic models of plant growth can help disentangl
Stationarity is the property that the statistical properties,which can be the jointprobability distribution or moments,of a process (or a system) are time invar
超级电容器是一种新兴的储能元件,因其具有高比能量、良好的可逆性和长循环寿命,近年来国内外对超级电容器的应用研究非常活跃。利用超级电容器和电池组成混合动力系统,能够很好的满足电动汽车高功率密度输出场合的需要。从比功率的角度,超级电容器可以同二次电池并联使用,从而弥补蓄电池比功率性能低的缺陷;在比能量方面,二次电池又可以弥补超级电容器比能量低的不足。超级电容器最为瞩目的应用前景是将其应用于电动汽车,可
