This paper has presented a particle swarm optimization (PSO) based approach to handle a multi-objective integrated process planning and scheduling problem. The aim is to find a set of high-quality trade-off solutions. This is a combinatorial optimization problem with substantially large solution space, suggesting that it is highly difficult to find the best solutions with the exact search method....
The refractive index sensor for use of a stress MLPG in a side-hole singlemode fiber is proposed. The principle of operation is based on using of a long-period grating that is made by pressing a plate with periodic grooves against a short length of side-hole fiber. The resonance wavelengths are shifted as the two side-holes of the fiber core were filled with the different the refractive index liquids...
A new type fiber bending sensor based on a tilted fiber Bragg grating (TFBG) interacting with a multimode fiber (MMF) is presented. The sensing head is formed by insertion a small section of MMF between single-mode fiber (SMF) and the TFBG. The reflective power in the cladding modes is decreased with the increase of curvature.
