Fig. 3From: Nondestructive evaluation of oviposition behavior of the bamboo powderpost beetle, Dinoderus minutus, using X-ray computed tomography and acoustic emissionOutline of the measurement system for attenuation of elastic waves when the length (l) of the bamboo specimen was 40 mm. Elastic waves were input at seven points (×). The same procedure was repeated three times after the bamboo specimen was shortened by 10 mm each time (l = 30, 20, 10 mm)Back to article page
