✦ Synopsis

In this study, an undamped Du$ng's oscillator equation with time-dependent parameters has been considered. The time-varying part is expanded in a series of ultraspherical polynomials in the spirit of Sinha and Chou and only the constant part is retained. The non-linearity parameter is assumed to be small so that the number of iterations required is only two. The results compare well with those obtained by the Runge}Kutta fourth order method.

Linear lossy two-conductor transmission line can be modelled as dynamic two ports in the time domain, via the describing input and transfer impulse responses. This convolution technique is very e!ective when dealing with networks composed of transmission lines with frequency-dependent parameters and

## Abstract Climatology is one of the areas that rely on collecting huge quantities of data. The longer a time period is observed, the better; the more parameters are included, the better. But the human mind cannot easily extract useful information from the abundance of data; thus, many valuable fa
