The present paper investigates identification of indexed families L of recursively enumerable languages from good examples. We distinguish class preserving learning from good examples (the good examples have to be generated with respect to a hypothesis space having the same range as L) and class comprising learning from good examples (the good examples have to be selected with respect to a hypo...

this paper considers the problem of stable limit cycles generating in a class of uncertain nonlinear systems which leads to stable oscillations in the system’s output.this is a wanted behavior in many practical engineering problems. for this purpose, first the equation of the desirable limit cycle is achieved according to shape, amplitude and frequency of the required output oscillations. then,...
