Self Consistent and Renormalized particle-particle RPA in a Schematic Model [PDF]

open access: yes, 1998
The dynamical effects of ground state correlations for excitation energies and transition strengths near the superfluid phase transition are studied in the soluble two level pairing model, in the context of the particle-particle self consistent Random ...

Modeling of dielectrophoretic particle motion: Point particle versus finite‐sized particle

open access: yesELECTROPHORESIS, 2017
Dielectrophoresis (DEP) is a very popular technique for microfluidic bio‐particle manipulation. For the design of a DEP‐based microfluidic device, simulation of the particle trajectory within the microchannel network is crucial. There are basically two approaches: (i) point‐particle approach and (ii) finite‐sized particle approach.

Ecohydrological particle model based on representative domains [PDF]

open access: yesHydrology and Earth System Sciences, 2018
Non-uniform infiltration and subsurface flow in structured soils is observed in most natural settings. It arises from imperfect lateral mixing of fast advective flow in structures and diffusive flow in the soil matrix and remains one of the most ...

Eulerian Walkers as a model of Self-Organised Criticality [PDF]

open access: yes, 1996
We propose a new model of self-organized criticality. A particle is dropped at random on a lattice and moves along directions specified by arrows at each site. As it moves, it changes the direction of the arrows according to fixed rules. On closed graphs

Performance Comparison of Different Particle Size Distribution Models in the Prediction of Soil Particle Size Characteristics

open access: yesLand, 2022
Particle size distribution (PSD) is a rich source of information about soil properties, including soil gradation and soil particle size characteristics. This paper compared the PSD prediction ability of three types of mathematical model. We selected nine
