A Time-Discontinuous Galerkin Finite Element Method for the Solution of Impact Problem of Gas-Saturated Coal

open access: yesShock and Vibration, 2020
Based on the general Biot theory of saturated porous media, a modified time-discontinuous Galerkin finite element method (MDGFEM) is presented to simulate the structural dynamics and wave propagation problems of gas-saturated coal subjected to impact ...

Nonlocal Hydrodynamic Model with Viscosive Damping and Generalized Drude–Lorentz Term

open access: yesPhotonics, 2023
The response of plasmonic metal particles to an electromagnetic wave produces significant features at the nanoscale level. Different properties of the internal composition of a metal, such as its ionic background and the free electron gas, begin to ...

Graphyne-3: a highly efficient candidate for separation of small gas molecules from gaseous mixtures

open access: yesScientific Reports, 2021
Two-dimensional nanosheets, such as the general family of graphenes have attracted considerable attention over the past decade, due to their excellent thermal, mechanical, and electrical properties.

Representing Complex Evolving Spatial Networks: Geographic Network Automata

open access: yesISPRS International Journal of Geo-Information, 2020
Many real-world spatial systems can be conceptualized as networks. In these conceptualizations, nodes and links represent system components and their interactions, respectively. Traditional network analysis applies graph theory measures to static network

Where do winds come from? A new theory on how water vapor condensation influences atmospheric pressure and dynamics [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
Phase transitions of atmospheric water play a ubiquitous role in the Earth's climate system, but their direct impact on atmospheric dynamics has escaped wide attention. Here we examine and advance a theory as to how condensation influences atmospheric

Modeling kinetic partitioning of secondary organic aerosol and size distribution dynamics: representing effects of volatility, phase state, and particle-phase reaction [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
This paper describes and evaluates a new framework for modeling kinetic gas-particle partitioning of secondary organic aerosol (SOA) that takes into account diffusion and chemical reaction within the particle phase.

Feedforward Nonlinear Control Using Neural Gas Network

open access: yesComplexity, 2017
Nonlinear systems control is a main issue in control theory. Many developed applications suffer from a mathematical foundation not as general as the theory of linear systems.

A geometric viewpoint on generalized hydrodynamics

open access: yesNuclear Physics B, 2018
Generalized hydrodynamics (GHD) is a large-scale theory for the dynamics of many-body integrable systems. It consists of an infinite set of conservation laws for quasi-particles traveling with effective (“dressed”) velocities that depend on the local ...

The Fluid Ionosphere

open access: yesAtmosphere
In this review paper, the equations of motion describing the fluid dynamics of the ionosphere are constructed step by step, so that any master or post-graduate student may get familiar with the general theory of the “traditional” approach to Ionospheric ...
