In a previous paper [E. Altshuler, Phys. Rev. Lett. 91, 014501 (2003)], the mechanism of "revolving rivers" for sandpile formation is reported: As a steady stream of dry sand is poured onto a horizontal surface, a pile forms which has a river of sand on one side flowing from the apex of the pile to the edge of the base. For small piles the river is steady, or continuous. For larger piles, it be...

Using experimental data obtained from in vitro bioaugmentation studies of a sand filter community of 13 bacterial species, we develop an individual-based model representing the in silico counterpart of this synthetic microbial community. We assess the inter-species interactions, first by identifying strain identity effects in the data then by synthesizing these effects into a competition struct...

The decomposition of deposited CsI and iodine oxides (IOx) aerosols on sand bed a metallic filter has been pursued under irradiation at 120 °C. On the sand, it was found that are decomposed by temperature effect into an inorganic specie assumed to be molecular iodine. might due surface effects grains as usually stable this temperature. IOx expected well retained (DF > 100) long height is high e...

in this paper, we present an application of the stochastic calculusto the problem of modeling electrical networks. the filtering problem have animportant role in the theory of stochastic differential equations(sdes). in thisarticle, we present an application of the continuous kalman-bucy filter for a rlcircuit. the deterministic model of the circuit is replaced by a stochastic model byadding a ...

in this research, the effect of friction between the liquid metal and the sand mould wall and the effect of passage of liquid through a vertical bend and through a ceramic filter on the fluid flow and the melt velocity has been studied by measuring the velocity of the melt and direct observation of the liquid flow through the different parts of a naturally-pressurized running system. the fricti...

A low voltage square root domain filter based on the MOSFET square law is proposed. Through the verification of HSPICE simulation, the extendibility and the reliability of the design procedure are proven. A design technique for current-mode square-root domain band-pass filter simulation in a 0.18 μm CMOS process. The basic building block consists of current-mode current mirrors, square-root cir...
