20.500.12556/RUL-32122 Analysis of strength grading of sawn timber based on numerical simulation The main problem in machine strength grading of wood lies in the grade determining parameters and machine grading parameters, which are all stochastic, and the correlation between them is of critical importance. Therefore it is difficult to reliably determine the grade of a particular piece. In order to understand the effectiveness and accuracy of machine grading a large number of experiments should be performed in which the non-destructive machine grading parameters as well as destructive grade determining parameters should be determined. So far we have had access to only a limited number of such experiments. The basic idea of this paper is to use experimental data only for the determination of statistical parameters - mean vector and variance - covariance matrix - and afterwards use these statistical parameters in numerical simulation of machine grading. This numerical procedure gave some valuable data on the average values and the variability of grading results which now make it easier to decide what sample size should be used in determining machine settings. timber grading numerical simulations optimization razvrščanje lesa numerične simulacije optimizacija true false false Springer Verlag Angleški jezik Angleški jezik Neznano 2015-07-10 10:12:10 2015-07-10 10:12:10 2022-11-21 15:07:43 0000-00-00 00:00:00 2004 0 0 Str. 493-505 Št. 7 Vol. 38 2004 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 624 0043-7719 10.1007/s00226-004-0254-4 2637921 9151749 Turkgrading_n.pdf Turkgrading_n.pdf 1 00A64132448C1572F39989C2AE769F1D 8139de720a7b3521212c05665d98c3f03ba798a956854f4aac77dc930ce74f27 0fc66d2c-a1ae-11eb-a523-00155dcfd717 20.500.12556/rul/419d081b-c941-4986-a568-e9ec3a9130cd https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=85632 Fakulteta za gradbeništvo in geodezijo 0 0 0
