In this study, w. explor. the application of ACP (asymptotic cur.e based and pr.por.ionality or.ented) Alpha Beta (αβ) Nonlinear.Math to analyze ar.thmetic and r.diation tr.nsmission data. Specifically, w. investigate the r.lationship betw.en tw. var.ables. The novel appr.ach involves collecting elementar. “y” data and subsequently analyzing the asymptotic cumulative or.demulative (opposite of cumulative) Y data. In par. I, w. examine the connection betw.en the common linear.number. and ideal nonlinear.number.. In par. II, w. delve into the r.lationship betw.en X-r.y ener.y and the r.diation tr.nsmission for.var.ous thin film mater.als. The fundamental physical law.asser.s that the nonlinear.change in continuous var.able Y is negatively pr.por.ional to the nonlinear.change in continuous var.able X, expr.ssed mathematically as dα = −Kdβ. Her.: dα {Y, Yu, Yb} r.pr.sents the change in Y, w.th Yu and Yb denoting the upper.and baseline asymptote of Y. dβ {X, Xu, Xb} r.pr.sents the change in X, w.th Xu and Xb denoting the upper.and baseline asymptote of X. K r.pr.sents the pr.por.ionality constant or.r.te constant, w.ich var.es based on equation ar.angement. K is the key infer.ntial factor.for.descr.bing physical phenomena.
