Possibilities of parameterization of the zero-order Brown model for indoor air forecasting based on the current measure of air state gain recurrence are considered. The key to the zero-order parametric Brown forecasting model is the selection of the

The main danger of a fire at an oil storage tank farm lies in its cascade spreading to neighboring tanks. This happens due to heating metal structures to the temperature of self-ignition of vapors of petroleum products. That is why cooling tanks is a
