In this paper, piecewise linear switched systems affected by both parameter variations and exterior disturbances are considered. The problem of synthesis of switching laws, which assure that the system state is ultimately bounded within a given compact set containing the origin with an assigned rate of convergence, is investigated. Given an uncertain switched linear system, we present a systema...

As David and Brierley (1968) pointed out, each political society in the world has its own law. In fact, it frequently happens that several laws coexist within the same state. Moreover, law is not static; it is in a state of flux, of evolution. The development of the law is shaped by logic, history, custom and utility, as well as the accepted standards of right conduct (Cardozo, 1921). It is the...

Societies build their interpretation and representation on the different phenomena in social, historical political processes, so also culture contains a set of beliefs, ideas, myths, norms, which give it identity, values, ends. Consequently, from democratic culture, citizen is encouraged to move public space, determined by actions, practices. As result these relationships, participation mechani...

It has been known for some time that for a large class of nonlinear field theories in Minkowski space with two-dimensional target space the complex eikonal equation defines integrable submodels with infinitely many conservation laws. These conservation laws are related to the area-preserving diffeomorphisms on target space. Here we demonstrate that for all these theories there exists, in fact, ...
