Enhancing the Iterative Smoothed Particle Hydrodynamics Method

Applied Sciences, 2021
Motivated by recent research on the iterative approach proposed for the smoothed particle hydrodynamics (ISPH) method, some ideas to improve the process are introduced.

Particle Production in Cosmology and Imaginary Time Method [PDF]

, 2001
After brief personal recollections of the author's long-time friendship with Misha Marinov the problem of particle production by classical time- varying scalar field is discussed.

Discrete element modeling of non-spherical particles using a spherical shape

REM: International Engineering Journal, 2020
Real non-spherical particles can be modeled using the Discrete Element Method (DEM) with sphere clusters, superquadrics, or polyhedral particles. However, in applications involving a considerable number of particles, the analysis can become impracticable.

A modified particle method for semilinear hyperbolic systems with oscillatory solutions [PDF]

, 2004
We introduce a modified particle method for semi-linear hyperbolic systems with highly oscillatory solutions. The main feature of this modified particle method is that we do not require different families of characteristics to meet at one point.

Discovery and quantification of plastic particle pollution in human blood.

Environment International, 2022
Plastic particles are ubiquitous pollutants in the living environment and food chain but no study to date has reported on the internal exposure of plastic particles in human blood.

Point-particle method to compute diffusion-limited cellular uptake [PDF]

, 2017
We present an efficient point-particle approach to simulate reaction-diffusion processes of spherical absorbing particles in the diffusion-limited regime, as simple models of cellular uptake.

Particle Methods as Message Passing [PDF]

2006 IEEE International Symposium on Information Theory, 2006
It is shown how particle methods can be viewed as message passing on factor graphs. In this setting, particle methods can readily be combined with other message-passing techniques such as the sum-product and max-product algorithm, expectation maximization, iterative conditional modes, steepest descent, Kalman filters, etc.

A new method for calculating particle coal matrix scale and its application

Meitan kexue jishu
There are abundant complex pores in the coal matrix, which provide a large amount of storage space and migration channels for methane. Diffusion is involved in the gas migration from the pore to the fracture.

Review of Particle-Based Computational Methods and Their Application in the Computational Modelling of Welding, Casting and Additive Manufacturing

Metals, 2023
A variety of particle-based methods have been developed for the purpose of computationally modelling processes that involve, for example, complex topological changes of interfaces, significant plastic deformation of materials, fluid flow in conjunction ...
