The inflation of this cuff at certain pressures produces signals that will be detected by a high-resolution pressure tensor, and this sends these signals to the computer.
where [sigma], p are the energy density and isotropic pressure, respectively, and P denotes the anisotropic pressure tensor of the fluid, [mu] is the unit timelike vector field, called flow vector field of the fluid associated with the 1-form y given by g(X, [mu]) = [gamma](X) for all X.
with [mu] as the unit timelike flow vector field of the fluid and P as the anisotropic pressure tensor, where the 1-form [alpha], associated with the torsion tensor [tau], corresponding to the semi-symmetric metric connection [?
Thus, the stress and pressure tensors for the offered system of shells and a sphere inside are obtained.
The given approach allows to receive analytically the values of pressure on the limits and inside the spheres, and also stress and pressure tensors.
