A contranormal subgroup is a subgroup whose normal closure in the group is the whole group. Hence a subgroup H of a group G is said to be totally contranormal if HK = K for each subgroup K of G. The purpose of this article is to study the influence of contranormal (totally contra...

This paper proposes a variable gain controller for a linear system with structured uncertainties. The proposed variable gain controller is based on LQ optimal control for the nominal system and consists of the optimal feedback gain and a time-varying adjustable parameter which is...

Okike’s Merged Irregular Transposition Cipher is a new technique for enciphering information along the superhighway. In this method, a message to be transmitted along the superhighway is first split into parts and each part is encrypted separately before transmission occurs. The...
