A generalized rule for large piezoelectric response in perovskite oxide ceramics and its application for design of lead-free compositions
(American Institute of Physics, 2009-06-01)
We present a general rule for the perovskite oxide ceramics: "A large piezoelectric constant in ABO(3) perovskite ceramics can be obtained by tuning the weight ratio of A and B sites, WA/WB or WB/WA, to 3. Piezoelectric ...
Large piezoresistivity phenomenon in SiCN-(La,Sr)MnO3 composites
(AIP Publishing, 2009-02-01)
We present the results on SiCN-(La,Sr)MnO3 (LSMO) composites correlating the observed large piezoresistance behavior with the microstructural features and defect chemistry. Scanning electron microscopy characterization ...
Inexact Kleinman-Newton method for Riccati equations
(Siam Publications, 2009-03)
In this paper we consider the numerical solution of the algebraic Riccati equation using Newton's method. We propose an inexact variant which allows one control the number of the inner iterates used in an iterative solver ...
Mesh independence of Kleinman-Newton iterations for Riccati equations in Hilbert space
(Siam Publications, 2008)
In this paper we consider the convergence of the infinite dimensional version of the Kleinman-Newton algorithm for solving the algebraic Riccati operator equation associated with the linear quadratic regulator problem in ...
