Reliability Analysis of the Methyl Methacrylate Hardened Hybrid Poplar Wood

چکیده
An evaluated method based on Data envelopmentanalysis (DEA) to a second order conic robustcounterpart was developed and used to protect theperturbation of the output within an uncertaintyenvironment. This robust DEA was then evaluatedby studying the effect of the wood hardeningtreatment on the hybrid poplar clones. Thenumerical results indicated that the performance ofthe methyl methacrylate (MMA) hardened hybridpoplar woods varied among clones. The reliabilityalso suggested that the optimization of hardeningtreatment could be done by selecting hybrid poplarclone types and the amount of impregnatedchemicals in the future experiments.

Fire-retarding properties of wollastonite nanofibers in poplar wood (Populus nigra) were studied here. Some physical properties such as water absorption, volumetric swelling and anti-swelling efficiency (ASE) were also measured. Specimens were prepared according to the ISO 11925 specifications for the fire-retarding properties and according to the ASTM D4446 -2002 specifications for th...
