Fractional derivative in time variable is introduced into the Fokker-Planck equation of a population growth model. It’s solution, the KNO scaling function, is transformed into the generating function for the multiplicity distribution. Formulas of the factorial moment and the Hj moment are derived from the generating function, which reduces to that of the negative binomial distribution (NBD), if...
molecular dynamics simulation has been performed to analyze the effect of the presence of gold nanoparticle on dynamics of kob-anderson binary lennard-jones (blj) mixture upon supercooling within the framework of the mode coupling theory of the dynamic glass transition. the presence of gold nanoparticle has a direct effect on the liquid structure and causes the peaks of the radial distribution ...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
the phytoplankton structure and dynamics were analysed in relation to abiotic variables inpaso de las piedras reservoir, argentina. phytoplankton driving forces were explored using a functionalapproach. a total of 15 functional groups were identified among which d, p, h1, f, j and c were the mostimportant. a canonical variate analysis indicated that the categorization of the species in function...
We present numerical solutions of the equations of motion of the driven spring-block model with stick-slip dynamics. The system consists of an array of N masses which describes the statistical and dynamic properties of dissipative systems. In this study, we are interested in very low and very high velocity regimes. We show that there is a clear shift in the distribution of slip-force when we ...
In this research, the effects of foulings on the outer surface of a marine vessel have been studied using the Computational Fluid Dynamics (CFD) methods. To this end, a proper turbulence model was considered and validated for the simulations. The simulation results for different fouling grades indicated that existing of a thin layer of slime could make 4.58 % increase in drag force; however, fo...
Molecular dynamic simulation is a powerful method that monitors all variations in the atomic level in explicit solvent. By this method we can calculate many chemical and biochemical properties of large scale biological systems. In this work all-atom molecular dynamics simulation of polyalanine (PA) was investigated in the presence of 0.224, 0.448, 0.673, 0.897 and 1.122 M of guanidinium chlorid...
