A planar optical waveguide was formed in RbTiOPO4 crystal by 6.0-MeV oxygenion implantation vwith the dose of 2 × 1015 ions/cm2 at room temperature. Annealing
The behaviour of an excitable system under Gaussian white noise and exteal periodic forcing is systematically studied. In a large range of noise intensity, the
The brightness of a particular harmonic order is optimized for the chirp and initial phase of the laser pulse by genetic algorithm.The influences of the chirp a
A quasi-analytical model, i.e. the fractal model, for the transverse thermal dispersion conductivity in porous media is presented based on the fractal character
