Internal and external effects may severely decrease insulation performance. In order to examine external effects, samples are subjected to moisture and vibration effect Polymer samples are investigated by their fractal dimension which is a prominent tool for analyzing chaotic images. To simulate these chaotic surface tracking patterns Hidden Markov Models (HMM) are usedtrinfo:eu-repo/semantics/closedAccesssurface trackinghmmfractalConference Object966963WOS:000356351400220N/A
