    Environmental Protection in the Hard Balance between Fundamental Rights and Economic Reasons The paper aims at investigating the role of environmental protection to settle the conflict between Economics and the multilevel system of human rights protection (the EU’s supranational level, the ECHR and the Italian law). The analysis shows a progressive shift towards a balancing operation wherein the parameters of proportionality and reasonableness are crucial, as they need to be applied by the Legislator in the formulation of the rules and then by the Judge in the interpretation of these latter to set the equilibrium point among all the interests considered. Finally, the case of the biggest European steel plant (Ilva, Taranto) is examined, which fully expresses the underlying tension between the needs of a healthy environment and Economics

    A time-adaptive POD method for optimal control problems

    No full text
    In this paper we present a time adaptive technique for the solution of optimal control problems where the dynamic is given by an evolutive semi linear PDE. The method is based on a model reduction using a POD approximation coupled with a Hamilton-Jacobi equation characterizing the value function of the corresponding control problem for the reduced system. The choice of the POD basis is updated according to the evaluation of a numerical indicator in order to guarantee a global accurate solution. This is obtained via a sub-division of the time horizon into sub-intervals where the residual is below a given threshold. Some numerical tests illustrate the main features of this approach. © IFAC
