By employing the theoretical method based on tight-binding, we study electronic band structure of single-wall carbon nanotube (CNT) superlattices, which the system is the made of the junction between the zigzag and armchair carbon nanotubes. Exactly at the place of connection, it is appeared the pentagon–heptagon pairs as topological defect in carbon hexagonal network. The calculations are base...

In this research, a new technique is developed for reducing the order of high-order continuous interval systems. The model denominator derived using Anderson corollary and Routh table. Numerator by matching formulated Markov parameters (MPs) time moments (TMs). Distinctive features proposed approach are: (i) New simpler expressions MPs TMs; (ii) Retaining not only TMs but also while deriving mo...
