Center of Mass Estimation of Simple Shaped Magnetic Bodies Using Eigenvectors of Computed Magnetic Gradient Tensor
Computed Magnetic Gradient Tensor (CMGT) includes the first derivatives of three components of magnetic field of a body. At the eigenvector analysis of Gravity Gradient Tensors (GGT) for a line of poles and point pole, the eigenvectors of the largest eigenvalues (first eigenvectors) point precisely toward the Center of Mass (COM) of a body. However, due to the nature of the magnetic field, it i...
متن کاملEffects of flake size on mode-locking behavior for flake-graphene saturable absorber mirrors
After advent of graphene as a saturable absorber many experiments have been conducted to produce short pulse duration pulses. Here, we have measured the properties of flake-graphene saturable absorber mirrors of various flake sizes dependent on fabrication technique. These mirrors enabled us to obtain a large mode-locking bandwidth of 16nm in an erbium-doped fiber laser. Mirrors with large flak...
متن کاملCalcium apatite crystals in synovial fluid rice bodies.
BACKGROUND Rice bodies can occur in the joints in many rheumatic conditions, but they are most common in rheumatoid arthritis. They are generally believed to occur rarely in patients with osteoarthritis, but one study reported rice bodies with apatite crystals. OBJECTIVE To report on a series of joint fluids with rice bodies containing apatite clumps and examine their clinical pictures. MET...
متن کاملSonographic demonstration of hyperechoic fibrin coating of rice bodies in trochanteric bursitis: the "fried rice" pattern.
ntra-articular rice body formation is generally related to synovial inflammatory conditions such as tuberculous, pyogenic, rheumatoid, or seronegative inflammatory diseases.1,2 Occasionally, it does not have any underlying disorder.3,4 Various mechanisms of pathogenesis of rice bodies have been proposed, including sloughing from the microinfarcted synovium, de novo formation in the synovial flu...
متن کاملFlake Electrical Conductivity of Few-Layer Graphene
The Kubo formula for the electrical conductivity of per stratum of few-layer graphene, up to five, is analytically calculated in both simple and Bernal structures within the tight-binding Hamiltonian model and Green's function technique, compared with the single-layer one. The results show that, by increasing the layers of the graphene as well as the interlayer hopping of the nonhybridized p z ...
