Comparison Between LSCF-CGO and GSC-CGO Composite Cathodes on a CGO Electrolyte for IT-SOFC

Reconstruction of interfaces using CGO solutions for the Maxwell equations

We deal with the problem of reconstructing interfaces using complex geometrical optics solutions for the Maxwell system. The contributions are twofold. First, we justify the enclosure method for the impenetrable obstacle case avoiding any assumption on the directions of the phases of the CGO's (or the curvature of obstacle's surface). In addition, we need only a Lipschitz regularity of this sur...

PSO-CGO: A Particle Swarm Algorithm for Cluster Geometry Optimization

In this paper the authors present PSO-CGO, a novel particle swarm algorithm for cluster geometry optimization. The proposed approach combines a steady-state strategy to update solutions with a structural distance measure that helps to maintain population diversity. Also, it adopts a novel rule to update particles, which applies velocity only to a subset of the variables and is therefore able to...

CGO: G: Decoupling Symbolic from Numeric in Sparse Matrix Computations

Sympiler is a domain-speci c code generator that optimizes sparse matrix computations by decoupling the symbolic analysis phase from the numerical manipulation stage in sparse codes. The computation patterns in sparse numerical methods are guided by the input sparsity structure and the sparse algorithm itself. In many real-world simulations, the sparsity pattern changes little or not at all. Sy...

Microstructures of CGO and YSZ Thin Films by Pulsed Laser Deposition

Yttrium-stabilized zirconia (YSZ) and cerium gadolinium oxide (CGO) are well-known oxygen conductors for electrochemical applications such as gas sensors, gas separation membranes, and fuel cells. There is much interest to obtain these materials in the form of dense thin films in order to reduce ohmic resistance of devices and consequently allow for lower operating temperatures. In order to be ...
