Lanthanum (La) doped Ceria (CeO2) has attracted considerable interest as a candidate material for thermal barrier coating (TBC) because of its low thermal conductivity and potential capability to be operated above 1250°C. In this study, La2Ce2O7 powder was synthesized through the ball mill method. The crystal structure of La3+ su...

We present a reduced basis method for parametrized linear elliptic partial differential equations (PDEs) in least-squares finite element framework. A rigorous and reliable error estimate is developed, shown to bound the with respect exact solution of PDE, contrast estimates that measure finite-dimensional (high-fidelity) approximation. It first-order formulation key ingredient. The demonstrated...

In this paper, we introduce a new reduced basis methodology for accelerating the computation of large parameterized systems high-fidelity integral equations. Core to our is use coarse-proxy models (i.e., lower resolution variants underlying equations) identify important samples in parameter space from which high quality then constructed. Unlike more traditional POD or greedy methods constructio...

Purpose The maximum entropy snapshot sampling (MESS) method aims to reduce the computational cost required for obtaining reduced basis purpose of model reduction. Hence, it can significantly original system dimension whilst maintaining an adequate level accuracy. this paper is show how these beneficial results are obtained. Design/methodology/approach so-called MESS used reducing two nonlinear ...
