In this paper, a model of torque dependence of critical current in a Bi2223/Ag composite concentric cylinder is analyzed. Based on the hypothesis of planar section and elastic linear strengthening constitutive theory, the relation between torque and shear strain is firstly obtained. Then a linear weakening relation between critical current density and shear(More)
A through study of the postural stability of 40 subjects has been conducted with a stabilometer and the computer system. The subjects stand on the testing platform for 10 seconds and meanwhile the sum of frequency spectrum is being analyzed. The most men subjects maintain a little sway well within timits during the trials. The testing conditions include(More)
