Learning is the nature for human being. For example, a school-student learns a subject by doing exercise and home-work. Then, a school-teacher grades the school-student’s works. From this student and teacher interaction, the ability of the student mastering the subject is a feedback that the previous teaching method is successful or failure. As a result, the teacher will change the teaching met...

We derive the low-temperature properties of spin-S quantum Heisenberg magnets from the Gibbs free energy G(M ) for fixed order parameter M. Assuming that the low-lying elementary excitations of the system are renormalized spin waves, we show that a straightforward 1/S expansion of G(M ) yields qualitatively correct results for the low-temperature thermodynamics, even in the absence of long-rang...

Fault detection and isolation is an area of engineering dealing with designing on-line protocols for systems that allow one to identify the existence faults, pinpoint their exact location, overcome them. We consider case multi-agent systems, where faults correspond disappearance links in underlying graph, simulating a communication failure between corresponding agents. study which agents contro...

In order to increase the number of situations in which an intelligent vehicle can operate without human intervention, lateral control is required accurately guide it a reference trajectory regardless shape road or longitudinal speed. Some studies address this problem by tuning controller for low and high speeds including output adaptation law. paper, strategy framed Model-Free Control paradigm ...
