Application of Eigenvalues and Eigenvectors in Correlating Density and Fire Properties of Some Selected Woods in South-East Nigeria

Abstract

Data sourced from literature for wood density (WD) and fire properties for fifteen Nigerian woods were analysed. The fire properties are ignition time (IT), flame propagation rate (FPR), flame duration (FD), afterglow time (AGT), ash formation (AF) and limiting oxygen index (LOI). The aim was to correlate density and fire properties of wood using eigenvalues and eigenvectors. The analysis tool adopted was the statisticalanalysis system (SAS) where principal component and regression analyses were performed. Based on the presented data and analyses, WD was found to relate well with FPR, AGT and LOI with an adjusted R-Square = 83% while the other three parameters: IT, FD and AF constitute random noise.
