Eggshell crack detection by acoustic impulse response and support vector machine
Eggshell crack detection acoustic impulse response frequency feature support vector machine
2009/3/4
This paper investigates the effect of support vector machine (SVM) for the classification of intact and cracked eggs. The four frequency features of the sound impulse resonance of an egg excited wit...
Crack tortuosity in swelling clay soils
swelling soil crack network crack connectedness planar tortuosity spatial tortuosity
2008/11/26
A relationship between the planar and spatial tortuosities of a statistically isotropic crack network in a clay soil is derived from the fact that connected cracks outline peds and are their boundarie...
Crack width, cross-section area, and volume in swelling clay soils
geometry swelling soils shrinkage cracks
2008/11/26
A model is presented for prediction of crack network geometry in clay soils. The starting point is the similarity between a crack network in rocks and that in soils, and, hence, principles of multiple...
Effect of various fertilization levels on the crack resistance of horse beans
horse bean seeds mechanical damage fertilizer dose moisture content
2008/11/19
Static compression tests were carried out on horse bean seeds within the scope of tests on micro tensile tester, Model Zwick 1425. The maximum value of force [N] causing bean crack and sample deformat...
Evaluation for soil of crack net connectedness and critical stress-intensity factor
soil mechanics clods cracking strength scale effect
2008/11/19
Based on data reflecting size effect of soil clod strength, and on theoretical computation of clod strength, an approach was suggested for evaluation of crack net connectedness and critical stress-in...
