Chaos control of a nonlinear oscillator with shape memory alloy using an optimal linear control: Part I: Ideal energy source
(Nonlinear Dynamics, 2009-01-01) [Artigo]
In this paper, an optimal linear control is applied to control a chaotic oscillator with shape memory alloy (SMA). Asymptotic stability of the closed-loop nonlinear system is guaranteed by means of a Lyapunov function, ...
Structural phase transition study of FePt alloys using ab initio calculation
(Materials Science and Engineering A: Structural Materials Properties Microstructure and Processing, 2009-09-25) [Artigo]
The FePt alloy undergoes the cubic to tetragonal lattice transformation in the ferromagnetic state. We calculated the electronic structure for both cubic and tetragonal structures using the FPLAPW method with APW + lo. ...
