Abstract A separable covariance model can describe the among-row and among-column correlations of a random matrix permits likelihood-based inference with very small sample size. However, if assumption separability is not met, data analysis may misrepresent important dependence patterns in data. As compromise between unstructured estimation, we decompose into component complementary ‘core’ matri...

Following earlier work of Huggins and Nix [Ionics 6, 57 (2000)], several recent theoretical studies have used the shrinking core model to predict intraparticle Li concentration profiles and associated stress fields. A goal of such efforts is to understand and predict particle fracture, which is sometimes observed in degraded electrodes. In this paper we present experimental data on LiCoO2 and g...

Thermo-responsive hydrogels are a promising material for creating controllable actuators use in micro-scale devices, since they expand and contract significantly (absorbing or expelling fluid) response to relatively small temperature changes. Understanding such systems can be difficult because of the spatially- temporally-varying properties gel, complex relationships between fluid dynamics, ela...

This paper considers the problem of passing from a nonlinear simple-structure model to a low-order approximation by preserving simplicity. The approximation problem is often best posed as an `2 optimization problem. This optimization problem is the core of our order reduction method so-called system matrices optimization. The simplification is formulated as special secondary conditions which ca...
