recommendations! Published in 2020 at "International Journal for Numerical Methods in Fluids"

DOI: 10.1002/fld.4788

Abstract: The heat equation is solved by using a finite volume discretization in a domain that consists of a two‐dimensional central node and several one‐dimensional outgoing branches. Several interface connection options to match the submodels set… read more here.

DOI: 10.1007/s10589-017-9924-7

Abstract: Decomposition methods for optimal spanning trees on graphs are explored in this work. The attention is focused on optimization problems where the objective function depends only on the degrees of the nodes of the tree.… read more here.

DOI: 10.1007/s10589-019-00104-x

Abstract: We consider well-known decomposition techniques for multistage stochastic programming and a new scheme based on normal solutions for stabilizing iterates during the solution process. The given algorithms combine ideas from finite perturbation of convex programs… read more here.

DOI: 10.1007/s10589-019-00157-y

Abstract: We develop new variants of Benders decomposition methods for variational inequality problems. The construction is done by applying the general class of Dantzig–Wolfe decomposition of Luna et al. (Math Program 143(1–2):177–209, 2014) to an appropriately… read more here.

DOI: 10.1364/ao.414144

Abstract: The Jones pupil is a full description of imaging properties of projection lenses in optical lithography. The decomposition of the Jones pupil into components with clear physical meanings was studied previously; however, the decomposition method… read more here.

DOI: 10.3389/fnins.2021.749811

Abstract: While promising for high-capacity machine learning accelerators, memristor devices have non-idealities that prevent software-equivalent accuracies when used for online training. This work uses a combination of Mini-Batch Gradient Descent (MBGD) to average gradients, stochastic rounding… read more here.
