In a model of radioactive decay of radon in the sample (222Rn). The model assumes that the probability of the decay of radon and its half-life depends on the fractal properties of the geological environment. The dependencies of the decay parameters of the fractal dimension of the medium.
The technique and algorithms for identifying structural components of non-sinusoidal voltage and current signals in the ship power system. The skeleton diagram and useful model of active compensator conducted emissions on the basis of wavelet transform.
A variant of the production of nanopowders of silica from natural hydrothermal solutions. Derived silica sols with the contents of SiO2 to 600 g/l³(43,0 wt. %) And the radius of the particles 29-135 nm.
