In the first linear zone, the apparent activation energy and

frequency factor were found to be in the range of 63.1-94.2 kJ/mol and 9.3E+3-5.03E+6, respectively.

The

frequency factor (A) and activation energy ([E.sub.a]) were obtained using Arrhenius and Kissinger methods.

where [D.sub.0] is the temperature independent

frequency factor, [k.sub.B] is the Boltzmann constant, and T is the temperature.

The activation energy [E.sub.A] of this relaxation is 1.32 [+ or -] 0.08 eV/atom (but may change with composition), and the

frequency factor [k.sub.0] is [10.sup.15.6[+ or -]1] [s.sup.-1].

The

frequency factor ([k.sub.i]), activation energy ([Ea.sub.i]) along with the [NH.sub.3] storage capacity ([OHM]) of the catalyst were determined based on the experimental method of Shost et al.

P3 is designed in consideration of the temporal

frequency factor based on P1.

On the other hand, it was observed that the values for the

frequency factor in the Arrhenius equation are different.

In [9] manage the interference based on fractional frequency reuse scheme; here the

frequency factor is reused in HetNet in LTE advanced.

Before proceeding to tackle the actual clustering phenomena to formulate the

frequency factor [omega], we will very briefly sketch the procedure and final result that have been successfully developed to fulfill objective (A) of the work, whereby the full, more accurate, four-level process scheme of Fig.
