The sensitivity of the random field Ising model to small random perturbations of the quenched disorder is studied via exact ground states obtained with a maximum-flow algorithm. In one and two space dimensions we find a mild form of chaos, meaning that the overlap of the old, unperturbed ground state and the new one is smaller than 1, but extensive. In three dimensions the rearrangements are ma...

We demonstrate that macromolecules in miscible polymer blends may behave as good, Theta, and poor polymeric solvents for each other. We construct a conceptual phase diagram, delineating the range of validity of the random-phase approximation, outside of which polymers contract or expand beyond their unperturbed dimensions, contrary to common assumptions. Remarkably, the correlation length for p...

This paper develops a new method of integral sliding mode control redesign for a class of perturbed nonlinear dissipative switched systems by modifying the dissipativity-based control law that was designed for the unperturbed systems. The nominal model is considered affine with matched and unmatched perturbations. The redesigned control law includes an integral sliding-based control signal such...

Schelling’s model of segregation, first described in 1969 [17], has become one of the best known models of self-organising behaviour. While Schelling’s explicit concern was to understand the mechanisms underlying racial segregation in large cities from a game theoretic perspective, the model should be seen as one of a family, arising in fields as diverse as statistical mechanics, neural network...

flexibility is one of the most important indicators of a supply chain .a flexible supply chain in the face of market changes and customer needs, must be responsive to the changes and needs, to be able to attract customers in the a competitive marketplace. being aware of the flexibility of a supply chain helps managers to solve problems and overcome deficiencies and increase the competitive adva...

rfid technology has great potential to improve the benefits of supply chain management. auto- manufacturing is a competitive industry that every player of it needs great operation efficiency to gain competitive advantage to survive. rfid systems are good enhancements to supply chain processes, therefore it's obvious that every industry has to pay great attention to this it solution, and in this...
