A method for determining knotty core sizes of standing Pinus patula trees based on tree ring sampling

open access: yesDendrochronologia, 2016
Abstract The objectives of this study were to develop and assess a method of using tree ring measurements in standing pruned Pinus patula trees for modelling the knotty core of the pruned section of a tree and to assess variability in knotty core diameters in the tree stem. A total of 170 trees from 17 compartments on a wide variety of growth sites

Effects of pruning on knotty core taper and form of Pinus radiata and Pinus pinaster

European Journal of Wood and Wood Products, 2016
Pruning is a key silvicultural intervention in order to obtain high quality wood products since it influences the size of the knotty core and the proportion of clear-wood. However, little is known about knotty core size and its distribution through the pruned stem in timber conifers. This paper describes methodologies to predict knotty core profile and

The Knotty Question of the Jet of PKS B1421-490

open access: yesAstrophysical Journal, 2005
We report the discovery of unusually strong optical and X-ray emission associated with a knot in the radio jet of PKS B1421-490. The knot is the brightest feature observed beyond the radio band, with knot/core flux ratios ∼300 and 3.7 at optical and X ...

Identificación del cilindro nudoso en imágenes Tc de trozas de Pinus radiata: Estudio comparativo

open access: yesMaderas: Ciencia Y Tecnologia, 2012
The aim of this study was to compare the accuracy of both the maximum likelihood classifier (ML) algorithm and another one based on an artificial neural networks classifier (ANN) algorithm for knotty core identification in CT images of pruned radiata ...
