Міждисциплінарний підхід до оцінювання еколого-соціальної безпеки водних об'єктів – джерел господарсько-питного водопостачання

In the article approach is offered for the estimation of water objects – sources of economic-drinkable water-supply, formed on theoretical bases of safety of man and environment. The complex of factors is presented, approaches and positions on the basis of which this estimation must produced in the conditions of increase of the anthropogenic loading

Stochastic ionization through noble tori: Renormalization results

We find that chaos in the stochastic ionization problem develops through the break-up of a sequence of noble tori. In addition to being very accurate, our method of choice, the renormalization map, is ideally suited for analyzing properties at criticality. Our computations of chaos thresholds agree closely with the widely used empirical Chirikov criterion
