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.

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.

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.

Experimental analysis for the dynamic initiation mechanism of debris flows
, 2016 Debris flow is one of the major secondary mountain hazards following the earthquake. This study explores the dynamic initiation mechanism of debris flows based on the strength reduction of soils through static and dynamic triaxial tests.

Foundations of Engineering Mathematics Applied for Fluid Flows
Axioms, 2021 Based on a brief historical excursion, a list of principles is formulated which substantiates the choice of axioms and methods for studying nature. The axiomatics of fluid flows are based on conservation laws in the frames of engineering mathematics and ...

Dynamic migration flow modeling
Security Dialogues /Безбедносни дијалози, 2017 The paper presents a SD model that analyses migrant/refugee flow, taking into account the following parameters: political decisions of the countries on migrant routes (political intervention), socio-economic factors, the porosity of state borders, criminal activities, public opinion, health, climate, and environmental conditions, etc.
