The maximum flow in dynamic networks [PDF]
Computer Science Journal of Moldova, 2005 The dynamic maximum flow problem that generalizes the static maximum flow problem is formulated and studied. We consider the problem on a network with capacities depending on time, fixed transit times on the arcs, and a given time horizon.

Large-scale physical modelling study of a flexible barrier under the impact of granular flows [PDF]
Natural Hazards and Earth System Sciences, 2018 Flexible barriers are being increasingly applied to mitigate the danger of debris flows. However, how barriers can be better designed to withstand the impact loads of debris flows is still an open question in natural hazard engineering. Here we report

Game-Theoretic Approach for Solving Multiobjective Flow Problems on Networks [PDF]
Computer Science Journal of Moldova, 2005 The game-theoretic formulation of the multiobjective multicommodity flow problem is considered. The dynamic version of this problem is studied and an algorithm for its solving, based on the concept of multiobjective games, is proposed.

Dynamics of flowing 2D skyrmions [PDF]
Journal of Physics: Condensed Matter, 2021 Abstract We investigate, numerically, the effects of externally imposed material flows on the structure and temporal evolution of liquid crystal (LC) skyrmions. The dynamics of a 2D system of skyrmions is modeled using the Ericksen–Leslie theory, which is based on two coupled equations, one for material flow and the other for the ...

Overview of Different Flow Diverters and Flow Dynamics
Neurosurgery, 2019 Abstract Over the past decade, flow diverter technology for endocranial aneurysms has seen rapid evolution, with the development of new devices quickly outpacing the clinical evidence base. However, flow diversion has not yet been directly compared to surgical aneurysm clipping or other endovascular procedures.

Shear-induced diffusion and dynamic heterogeneities in dense granular flows
Frontiers in Physics, 2022 We study two-dimensional dense granular flows by molecular dynamics simulations. We quantify shear-induced diffusion of granular particles by the transverse component of particle displacements.

Protecting environmental flows through enhanced water licensing and water markets [PDF]
Hydrology and Earth System Sciences, 2015 To enable economically efficient future adaptation to water scarcity some countries are revising water management institutions such as water rights or licensing systems to more effectively protect ecosystems and their services.

Two problems concerning dynamic flows in node and arc capacitated networks [PDF]
Computer Science Journal of Moldova, 1997 This paper presents two problems concerning dynamic flow in node and arc capacitated networks: (1) maximal dynamic flow; (2) feasible dynamic flows.
