Let G be a transitive group.We mainly prove that the group(G,a)is primitive for a given special permutation a and the semigroup(G,a)is synchronizing for a given special transformationα.
Wind energy systems (WESs) based on doubly-fed induction generators (DFIGs) have enormous potential for meeting the future demands related to clean energy. Due to the low inertia and intermittency of power injection, ...
