WebJul 18, 2024 · Fiber Bragg grating (FBG) sensors, a type of optical fiber sensor, have been recognized as ideal choices for aviation structure strain measurement [].FBG sensors have many advantages such as their small size, high sensitivity, multiplexing capability and immunity to electromagnetic interference [12,13,14].FBG is made by inscribing grating in … WebA modified Bragg-Williams statistical model with nearest-neighbor magnetic exchange and chemical interactions and an additional Zeeman energy term has been used to predict an increase in the critical ordering temperature T order of Fe-Co alloys in the presence of a large magnetic field T order 20 K near equiatomic composition for H=100 T .
WebA three-sublattice Bragg-Williams model of a triangular lattice gas with repulsive nearest-neighbor interactions is presented. It is intended to represent intercalated Li{sup +} in Li{sub x}TiS{sub 2} . An order-disorder phase diagram and thermodynamic functions are computed. In particular the incremental capacity is calculated and compared ... WebThe Gorsky, Bragg and Williams model. In order to evaluate the functions g (5) and E s), we need to know the distribution of the atoms on the lattice for the given value of s. Two …
