A computer vision-based lumber production planning system (CVLPPS) is described. Computer axial tomography (CT or CAT) images of hardwood logs are analyzed for identi®cation and classi®cation of internal log defects. Individual CT image slices are analyzed for detection of 2D defects which are correlated across CT image slices in order to establish 3D support and identify true 3D defects. CVLPP...

Exposure to inhalable wood dust and compliance with the British Control of Substances Hazardous to Health (COSHH) Regulations 1999 were assessed at a representative cross-section of the British woodworking industry. Median exposures ranged from 1.5 to 2.8 mg/m(3) across the selected industry groups, the lowest being in sawmilling and planing of wood. Overall, 27% of values exceeded the maximum ...

This study demonstrates that a decrease of the water-mass density below 1000m has led to pattern see-saw shift in Gulf Stream position between 74° and 50° W longitude during 1993-2017, with New England Seamounts as pivot point. The moved northward upstream region shifted southward downstream. Our EOF analyses satellite altimeter data demonstrate second mode (EOF2) represents changes strength th...

esearchers in the Department of Industrial and Manufacturing Systems Engineering at the University of Missouri-Columbia, in collaboration with the Southern Research Station of the USDA Forest Service, recently developed a hardwood log sawing simulator for use by the hardwood sawmill industry. LogCast (Log Computer Aided Sawyer Trainer) was designed to be used as a training tool for sawyers in p...

Artificial Intelligence (AI) techniques are used for solving the intractable engineering problems. In this study, it is aimed to study the application of artificial bee colony algorithm for predicting the performance of circular diamond saw in sawing of hard rocks. For this purpose, varieties of fourteen types of hard rocks were cut in laboratory using a cutting rig at 5 mm depth of cut, 40 cm/...
