The first term is the DExp which varies with time through temperature history experienced experimentally.
In case of ramping temperature, the mean value of DExp changes its location with time in a similar manner to the isothermal temperature case, with logarithmic term replaced by a LambertW function [24, 25].
DExp = exp ([[integral].sup.t.sub.0] [k.sub.0][e.sup.E/RT] dt) (6)
Among procedures based on least squares fitting are nonlinear curve fitting method (NLCF) [19] applied to Pulse function parameters and Marquardt least squares method [35] applied to DEXP [36], Heidler's function [37-39], Pulse function [39], and NPAEFs [26].
DEXP function parameters are obtained in [36] by Marquart least squares method in order to approximate current waveshape of typical negative first stroke from [1].
Heidler's, Pulse, and DEXP functions were optimized by using Marquart least squares method in order to represent this set of measured data.

The adverse effects of increased Dexp in a developing country such as Pakistan are likely to exacerbate the existed poverty since almost all the military hardwares are imported.
The adverse effects of Dexp have not deterred countries from stockpiling military arsenals.
On the other hand, the large size of Dexp in presence of high budget deficits, declining development expenditure and increasing debt services on account of exploding public debt got the attention of researcher on the subject.
