Water Resources Research, Volume 62, Issue 1, January 2026.Abstract Understanding how snowmelt is partitioned into different hydrologic flowpaths/storages—and how this partitioning varies over time—is essential for predicting water availability and quality under climate variability. In this study, we examine the time‐variance of snowmelt partitioning patterns (SPP) in response to interannual variations in ...

International Journal of Energy Research, Volume 2026, Issue 1, 2026.The utilization of clean hydrogen energy in eco‐friendly mobility systems has gained increasing attention in the pursuit of carbon neutrality. As demand for hydrogen mobility rapidly grows, it becomes essential to expand and distribute hydrogen charging stations, thereby increasing the need for an efficient hydrogen compression process.

Optimal control of probability density functions of stochastic processes
Mathematical Modelling and Analysis, 2010 A Fokker‐Planck framework for the formulation of an optimal control strategy of stochastic processes is presented. Within this strategy, the control objectives are defined based on the probability density functions of the stochastic processes.

On segmentation model for vector valued images and fast iterative solvers
Advances in Difference Equations, 2018 In this paper, we propose a new convex variational model for segmentation of vector valued images. The data term of the proposed model is based on the coefficient of variation, which works well in vector valued images having intensity inhomogeneity.

Multilevel acceleration of scattering-source iterations with application to electron transport
Nuclear Engineering and Technology, 2017 Acceleration/preconditioning strategies available in the SCEPTRE radiation transport code are described. A flexible transport synthetic acceleration (TSA) algorithm that uses a low-order discrete-ordinates (SN) or spherical-harmonics (PN) solve to ...

The Mixed Finite Element Multigrid Preconditioned MINRES Method for Stokes Equations
Journal of Applied Fluid Mechanics, 2016 The study considers the saddle point problem arising from the mixed finite element discretization of the steady state Stokes equations. The saddle point problem is an indefinite system of linear equations, a feature that degrades the performance of any
