Evaluation of Yield Improvements in Machine vs. Visual Strength Grading for Softwood Species

نویسندگان

چکیده

The current national standard for strength grading in Spain is based on a visual classification, which, softwood species with small cross-sections (with thickness equa tol or less than 70 mm), establishes two different grades (ME-1 and ME-2). These are assigned to the classes C24 C18, respectively, maritime radiata pines, C27 C18 Scots pine, according European EN-1912:2012. production of engineered wood products, such as glulam cross-laminated timber increasing worldwide. machine using non-destructive testing provides industry more reliable, fast, consistent method grading. With this background mind, study presents yield comparison vs. those three pine from Spain. settings were obtained EN 14081-2:2019, providing several possible grade combinations. Results allow new possibilities improve structural studied timber, thus material optimization.

Combined Visual and Machine Strength Grading

The aim of this study was to show the possibility of the classification of structural timber (European spruce) into strength class C35 according to EN 338 by using combined visual and machine strength grading techniques. Three different visual machine strength grading combinations are devised for allocating sawn timber into strength class C35. They are composed on the one hand of the visual gra...

Training Visual Imagery: Improvements of Metacognition, but not Imagery Strength

Visual imagery has been closely linked to brain mechanisms involved in perception. Can visual imagery, like visual perception, improve by means of training? Previous research has demonstrated that people can reliably evaluate the vividness of single episodes of imagination - might the metacognition of imagery also improve over the course of training? We had participants imagine colored Gabor pa...
