Abstract: When statistical analyses consider multiple data sources, Markov melding provides a method for combining the source-specific Bayesian models. Markov melding joins together submodels that have a common quantity. One challenge is that the prior for… read more here.

DOI: 10.1016/j.cma.2018.02.024
Abstract: Abstract We propose a new numerically stable sequential implicit method for coupled flow and finite-strain multiplicative elastoplastic geomechanics. We find from stability analysis that the sequential method that solves the flow problem first by fixing… read more here.

DOI: 10.1109/access.2022.3168160
Abstract: We propose finite-difference time-domain (FDTD) modeling suitable for healthy skin, basal cell carcinoma, dysplastic pigmentary nevus, and non-dysplastic pigmentary nevus in the frequency range of 0.25 THz to 1.05 THz. Toward this purpose, we utilize… read more here.

DOI: 10.1109/lcsys.2020.2999864
Abstract: The potential for numerical instabilities of Dynamic Mode Decomposition (DMD), which assumes the completeness of the eigenspace is discussed for cases where the underlying system is defective or nearly defective. A numerically stable approach based… read more here.
