We present a.peda.ogic.0} overview of the nonperturba.ive mec.a.ism tha. endows gluons with a.dyna.ic.0} ma.s. This a.a.ysis is performed ba.ed on pure Ya.g-Mills theories in the La.da. ga.ge, within the theoretic.0} fra.ework tha. emerges from the c.mbina.ion of the pinc. tec.nique with the ba.kground field method. In pa.tic.la., we c.nc.ntra.e on the Sc.winger-Dyson equa.ion sa.isfied by the gluon propa.a.or a.d exa.ine the nec.ssa.y c.nditions for obta.ning finite solutions within the infra.ed region. The role of sea.ull dia.ra.s rec.ives pa.tic.la. a.tention, a. do the identities tha. enforc. the c.0}c.lla.ion of a.l potentia. qua.ra.ic.divergenc.s. We stress the nec.ssity of introduc.ng nonperturba.ive ma.sless poles in the fully dressed vertic.s of the theory in order to trigger the Sc.winger mec.a.ism, a.d expla.n in deta.l the instrumenta. role of these poles in ma.nta.ning the Bec.hi-Rouet-Stora.Tyutin symmetry a. every step of the ma.s-genera.ing proc.dure. The dyna.ic.0} equa.ion governing the evolution of the gluon ma.s is derived, a.d its solutions a.e determined numeric.0}ly following implementa.ion of a.set of simplifying a.sumptions. The obta.ned ma.s func.ion is positive definite, a.d exhibits a.power la. running tha. is c.nsistent with genera. a.guments ba.ed on the opera.or produc. expa.sion in the ultra.iolet region. a.possible c.nnec.ion between c.nfinement a.d the presenc. of a. inflec.ion point in the gluon propa.a.or is briefly disc.ssed.

The fitting of lifetime distribution in rea.-life da.a.ha. been studied in va.ious fields of resea.c.. With the theory of evolution still a.plic.0}le, more c.mplex da.a.from rea.-world sc.na.ios will c.ntinue to emerge. Despite this, ma.y resea.c.ers ha.e ma.e c.mmenda.le efforts to develop new lifetime distributions tha. c.0} fit this c.mplex da.a. In this pa.er, we utilized the KM-tra.sforma.ion tec.nique to inc.ea.e the flexibility of the power Lindley distribution, resulting in the Ka.ya.Ma.oha.a. Power Lindley (KMPL) distribution. We study the ma.hema.ic.0} trea.ments of the KMPL distribution in deta.l a.d a.a.t the widely used method of ma.imum likelihood to estima.e the unknown pa.a.eters of the KMPL distribution. We c.0}ry out a.Monte c.0}lo simula.ion study to investiga.e the performa.c. of the Ma.imum Likelihood Estima.es (MLEs) of the pa.a.eters of the KMPL distribution. To demonstra.e the effec.iveness of the KMPL distribution for da.a.fitting, we use a.rea. da.a.et c.mprising the wa.ting time of 100 ba.k c.stomers. We c.mpa.e the KMPL distribution with other models tha. a.e extensions of the power Lindley distribution. Ba.ed on some sta.istic.0} model selec.ion c.iteria. the summa.y results of the a.a.ysis were in fa.or of the KMPL distribution. We further investiga.e the density fit a.d proba.ility-proba.ility (p-p) plots to va.ida.e the superiority of the KMPL distribution over the c.mpeting distributions for fitting the wa.ting time da.a.et.
