Optimisation of the simulation particle number in a Lagrangian ice microphysical model
Lagrangian ice particle physics EULAG - LCM code simulation of ice particles the micro physics statistical convergence
2014/12/18
This paper presents various techniques to speed up the Lagrangian ice microphysics code EULAG-LCM. The amount of CPU time (and also memory and storage data) depends heavily on the number of simulation...
A Relationship between the Comoving Particle Number and the Effective Cosmological Constant
Comoving Particle Number the Effective Cosmological Constant General Physics
2012/5/28
In order to discuss and obtain the remaining inflaton potential, we introduced an idea called "effective static friction" in our last paper to balance the "force", $\frac{dV}{d\phi}|_{\phi=\phi(t_{res...
Identity Method for Particle Number Fluctuations and Correlations

2011/2/25
Atmospheric particle number size distributions (size range 0.003–10 μm) were measured between March 2008 and August 2009 at Shangdianzi (SDZ), a rural research station in the North China Plain. These ...
Inter-community variability in total particle number concentrations in the eastern Los Angeles air basin
particle number the eastern Los Angeles air basin
2010/12/20
Ultrafine Particles (UFP) can display sharp gradients in their number concentrations in urban environment due to their transient nature and rapid atmospheric processing. The ability of using air pollu...
