in this paper, the effect of the brownian term in natural convection of cuo-water nanofluid inside a partially filled porous cavity, with internal heat generation has been studied. it is assumed that the viscosity and thermal conductivity of nanofluid consists of a static part and a brownian part of which is a function of temperature and the volume fraction of nanofluid. because of internal hea...

DLS measures Brownian motion and relates this to the size of the particles. Brownian motion is the random movement of particles due to the bombardment by the solvent molecules that surround them. The larger the particle or molecule, the slower the Brownian motion will be. Smaller particles are "kicked" further by the solvent molecules and move more rapidly. An accurately known temperature is ne...

We use the Brownian dynamics with hydrodynamic interactions simulation in order to describe the movement of an elastically coupled dimer Brownian motor in a ratchet potential. The only external forces considered in our system were the load, the random thermal noise and an unbiased thermal fluctuation. We observe differences in the dynamic behaviour if hydrodynamic interactions are considered as...

The topological constraints on Brownian walks are a long standing subject of interest in mathematics and polymer physics. A particularly fruitful example is the study of the winding angle θ, the continuous angle swept by the movement around a set of points (curves) in two (three) dimensions . In a plane, the probability distribution at large time or length l for the winding angle of a Brownian ...

Brownian motion refers to the mathematical models that are used to describe the random movement of particles immersed in a fluid. This random movement was discovered by botanist Robert Brown, in 1827, while studying pollen grains in water under the microscope. One of the first to describe Brownian motion was Thorvald N. Thiele, in 1880, in a paper on the method of least squares. In 1900, Louis ...

Fractional Brownian motion has been suggested as a model for the movement of log share prices which would allow long-range dependence between returns on different days. While this is true, it also allows arbitrage opportunities, which we demonstrate both indirectly and by constructing such an arbitrage. Nonetheless, it is possible by looking at a process similar to the fractional Brownian motio...
