Accurate estimation of log MOE from non-destructive standing tree measurements

چکیده
A novel non-destructive method has been developed to predict modulus of elasticity (MOE) logs using measurements taken from cores extracted discs. The trees were felled and cut into allow validation our method; however, similar results would be obtained if the standing trees. shows that a single core breast height is sufficient MOE logs, allowing early grading sorting for optimal use processing. Early estimation log allows efficient which can improve financial return reduce wastage wood. This work aims accurately on was predicted ultrasound conducted small segments two different approaches: segment average integral average. Sixty-eight locally F1 F2 hybrid pines (slash pine × Caribbean hybrids, Pinus elliottii var. P. caribaea hondurensis (PEE PCH cross)) validate results. Beam Identification by Non-destructive Grading (BING) used measure reference dynamic (BING-MOE) each log, this compared with estimated MOE.

Acoustic-Based Non-Destructive Estimation of Wood Quality Attributes within Standing Red Pine Trees
The relationship between acoustic velocity (vd) and the dynamic modulus of elasticity (me), wood density (wd), microfibril angle, tracheid wall thickness (wt,), radial and tangential diameters, fibre coarseness (co) and specific surface area (sa), within standing red pine (Pinus resinosa Ait.) trees, was investigated. The data acquisition phase involved 3 basic steps: (1) random selection of 54...
متن کاملLeaf area estimation by a simple and non-destructive method
In this study, the relation between leaf area and its dimensions was estimated using a non-destructive method. This method is based on this fact that the leaf shape does not change during the growing season. In this method, leaf area during the growing season is estimated based on the dimensions of the smallest leaf in the initial stage of plant growth or at any growth stage by measuring the le...
متن کاملNon - Destructive Measurements for Robust Technologies
Non Destructive Evaluation (NDE) has become an inseparable part of modern society. Be it the field of engineering, technology, or healthcare, NDE is being used right from cradle to tomb to optimize processes, manage quality, predict the life and limit liability avoiding accidents. While NDE science and technology was qualitative during the first half of 20 century, the liberalisation of economi...
متن کاملAccurate estimation of third-order moments from turbulence measurements
Politano and Pouquet’s law, a generalization of Kolmogorov’s four-fifths law to incompressible MHD, makes it possible to measure the energy cascade rate in incompressible MHD turbulence by means of third-order moments. In hydrodynamics, accurate measurement of thirdorder moments requires large amounts of data because the probability distributions of velocity-differences are nearly symmetric and...
