Measure for Approximation of Fourier Optics

The technique of Fourier holography is considered from the point of view of the construction of an algebraic model. It is shown that the technique yields a construction of a semigroup of fuzzy subsets with convolution as addition and correlation as subtraction. It is proved that in an approximation to linearity of the Fourier transformation, the Sugeno -measure, which takes fuzzy values, is an appropriate tool for Fourier optics.

The effect of current density and thickness of the active mass upon the corrosion rate of the spines of lead-acid battery plates

The effect of current density and the thickness of the active mass upon the corrosion of the spines of tubular lead-acid batteries has been determined by measuring the corrosion rate by the weight loss method. The presence of antimony in the alloy decreases the overvoltage of the corrosion reaction. Study of electrodes of different active mass layer thickness shows that with increase in thickness the corrosion rate decreases. If the thickness is above 3 mm, the corrosion rate remains constant, and is affected only by the nature of the alloy. The density of the active mass does not affect the corrosion behaviour of the electrodes. The experimental results confirm the validity of the oxygen corrosion model.
