A fast model-order reduction algorithm is proposed for microelectromechanical devices. By breaking the system
matrices obtained from FEM methods down into smaller ones, the proposed algorithm will reduce computational
cost and memory requirements required by the inversion operation of the system matrix. As an example,
experimental studies are presented for a linear-drive multiple-mode resonator demonstrating that predicted
results are in very good agreement with results from previous publications.
Quantum-dot Cellular Automata (QCA) is a nanotechnology which has
potential applications in future computers. In this paper, a
method for reducing the number of majority gates (a QCA logic
primitive) is developed to facilitate the conversion of SOP
expressions of three-variable Boolean functions into QCA majority
logic. Thirteen standard functions are proposed to represent all
three-variable Boolean functions and the simplified majority
expressions corresponding to these standard functions are
presented. By applying this method, a one-bit QCA adder, with only
three majority gates and two inverters, is constructed. We will
show that the proposed method is very efficient and fast in
deriving the simplified majority expressions in QCA design.
