Three dimensional (3D) hydrodynamical models of the evolution of marginally gravitationally unstable protoplanetary disks have shown that such disks are likely to form selfgravitating clumps that could become gas giant protoplanets, even when detailed thermodynamics is included [1]. Vertical convective motions appear to be crucial for providing a means of cooling the disk midplane sufficiently ...

OBJECTIVE Computational fluid dynamics (CFD) simulations of intracranial aneurysm hemodynamics usually adopt the simplification of the Newtonian blood rheology model. A study was undertaken to examine whether such a model affects the predicted hemodynamics in realistic intracranial aneurysm geometries. METHODS Pulsatile CFD simulations were carried out using the Newtonian viscosity model and ...

We have analyzed a nonsingular model with a variable cosmological term following the Carvalho et al. ansatz. The model was shown to approximate to the model of Freese et al. in one direction and to the Özer-Taha in the other. We have then included the effect of viscosity in this cosmology, as this effect has not been considered before. The analysis showed that this viscous effect could be impor...

Mixing rubber in an internal mixer is a complex nonlinear process in which viscosity of the rubber is one of the key quantities concerning end product quality. Since viscosity can’t be measured online, soft sensor methods for modelling viscosity are investigated to establish an online control of viscosity. This paper presents a black-box approach to modelling viscosity using an adaptive neuro-f...
