Alternating directions implicit integration in a general linear method framework
(Elsevier, 2021-05-15)Alternating Directions Implicit (ADI) integration is an operator splitting approach to solve parabolic and elliptic partial differential equations in multiple dimensions based on solving sequentially a set of related ... -
Linearly implicit GARK schemes
(Elsevier, 2021-03-01)Systems driven by multiple physical processes are central to many areas of science and engineering. Time discretization of multiphysics systems is challenging, since different processes have different levels of stiffness ... -
A multi-attribute supply chain network resilience assessment framework based on SNA-inspired indicators
(Springer, 2021-07-22)This study proposes a supply chain resilience assessment framework at the network (i.e. structural) level based on quantifying supply chain networks’ structural factors and their relationships to different resilience ... -
Multirate implicit Euler schemes for a class of differential-algebraic equations of index-1
(Elsevier, 2021-05-15)Systems of differential equations which consist of subsystems with widely different dynamical behaviour can be integrated by multirate time integration schemes to increase the efficiency. These schemes allow the usage of ... -
Multirate linearly-implicit GARK schemes
(Springer, 2021-12-28)Many complex applications require the solution of initial-value problems where some components change fast, while others vary slowly. Multirate schemes apply different step sizes to resolve different components of the ... -
Neural network based pore flow field prediction in porous media using super resolution
(2021)Previous works have demonstrated using the geometry of the microstructure of porous media to predict the ow velocity fields therein based on neural networks. However, such schemes are purely based on geometric information ... -
Partitioned exponential methods for coupled multiphysics systems
(Elsevier, 2021-03-01)Multiphysics problems involving two or more coupled physical phenomena are ubiquitous in science and engineering. This work develops a new partitioned exponential approach for the time integration of multiphysics problems. ... -
Regret in the Newsvendor Model with Demand and Yield Randomness
(Wiley, 2021-07-28)We study the fundamental stochastic newsvendor model that considers both demand and yield randomness. It is usually difficult in practice to describe precisely the joint demand and yield distribution, although partial ... -
Scenario-based cuts for structured two-stage stochastic and distributionally robust p-order conic mixed integer programs
(Springer, 2021-01-22)In this paper, we derive (partial) convex hull for deterministic multi-constraint polyhedral conic mixed integer sets with multiple integer variables using conic mixed integer rounding (CMIR) cut-generation procedure of ... -
Self-Supervised Graph Learning With Hyperbolic Embedding for Temporal Health Event Prediction
(IEEE, 2021-09-20)Electronic health records (EHRs) have been heavily used in modern healthcare systems for recording patients' admission information to health facilities. Many data-driven approaches employ temporal features in EHR for ... -
Subspace adaptivity in Rosenbrock-Krylov methods for the time integration of initial value problems
(Elsevier, 2021-03-15)The Rosenbrock–Krylov family of time integration schemes is an extension of Rosenbrock-W methods that employs a specific Krylov based approximation of the linear system solutions arising within each stage of the integrator. ... -
A Theoretical and Empirical Investigation of Feedback in Ideation Contests
(Wiley, 2019-11-11)Ideation contests are commonly used across public and private sectors to generate new ideas for solving problems, creating designs, and improving products or processes. In such a contest, a firm or an organization (the ...
