Various recovery and stress-splitting schemes are investigated numerically for an Oldroyd-B model within the general framework of a time stepping fractional-staged finite element formulation, that of a Taylor-Galerkin/pressurecorrection method with consistent streamline upwinding. Smooth and non-smooth planar flows are cited and both creeping and inertial conditions are considered. Problems add...

The geotropic conduct of young rats has been discussed in a previous paper (Crozier and Pincus, 1926-27) with special reference to the angle of orientation upon an inclined plane. It was found that the angle of orientation (0) is directly proportional to the logarithm of the gravitational component (g sin ~) in the creeping plane. This is explicable as the result of the distribution of the pull...

Fluid-sheared granular transport sculpts landscapes and undermines infrastructure, yet predicting the onset of sediment transport remains notoriously unreliable. For almost a century, this onset has been treated as a discontinuous transition at which hydrodynamic forces overcome gravity-loaded grain-grain friction. Using a custom laminar-shear flume to image slow granular dynamics deep into the...

A mathematical study on creeping flow of non-Newtonian fluids (power law model) through a nonuniform peristaltic channel, in which amplitude is varying across axial displacement, is presented, with slip effects included. The governing equations are simplified by employing the long wavelength and low Reynolds number approximations. The expressions for axial velocity, stream function, pressure gr...

Creeping dislocations in an elastic half-space are commonly used to model interseismic deformation at subduction zones, and might also apply to major intracontinental thrust faults such as the Main Himalayan Thrust. Here, we compare such models with a more realistic 2-D finite element model that accounts for the mechanical layering of the continental lithosphere and surface processes, and that ...

In this paper methodology to exploit creeping wave for body area network BAN communication reliability are described. Creeping wave propagation effects are visualized & analyzed. During this work Dipole, IA antennas various antennas were redesigned using existing designs and their propagation characteristics were verified for optimum performance when used on BANs. These antennas were then appli...

1 Correction to the Airy Approximation In Ref..1] and especially in Franz and Galle 2] one can nd correction terms to order O((ka) ?5=3) to the standard Airy approximation of the zeros l of the Hankel function H (1) (ka) in the complex-plane 1 : l = ka + e ii=3 (ka)

Quasi-2D experiments of a submerged sediment layer creeping downward were performed, varying the channel tilt and porous flow under respective thresholds for yielding. Logarithmic decay rates deformation are observed, with rate increasing both control parameters. A new dimensionless parameter, $P^*$, accounting mean gravity force effects on particle motion, allows collapse all results single cu...
