A modest in-plane magnetic field Bk is sufficient to destroy the fractional quantized Hall states at 1⁄4 5=2 and 7=2 and replace them with anisotropic compressible phases. Remarkably, we find that at larger Bk these anisotropic phases can themselves be replaced by isotropic compressible phases reminiscent of the composite fermion fluid at 1⁄4 1=2. We present strong evidence that this transition...

The stress distributions of filament in bent yarn have never been seen experimentally.So the stress distributions in the cross section and the longitudinal direction of bent undrawn Tetron filaments are studied photoelastically in this paper.As the results,it is known that when the curvature is small,the compressible stress is equal to the tensile stress and when it is large, the compressible o...

Due to their noise-like features, SAR images are difficult to acquire with compressed sensing techniques. However, some parts of the images, typically associated to man-made structures, are compressible and we investigate two techniques exploiting that information to allow a compressive acquisition of the whole image. These techniques result in a significant enhancement of the image quality com...

A major computational code called CERV was developed to determine complex equilibrium compositions of a nonideal mixture of numerous imperfect gases and compressible liquid and solid species with phase transitions for closed-vessel applications. This code minimizes Gibbs energy using reaction variables, in contrast to other major codes like BRL-Blake, BRCBagheera and NASA-CEA that use compositi...

Gravity waves arise in gravitationally stratified compressible flows at low Mach and Froude numbers, and these waves impose a sharp restriction on the time step. This paper presents a filtering strategy for the fully compressible equations based on normal-mode analysis that is used throughout the simulation to compute the fast dynamics and is able to damp only chosen modes. This method is based...

The purpose of this paper is to present asymptotically stable open boundary conditions for the numerical approximation of the compressible Navier-Stokes equations in three spatial dimensions. The treatment uses the conservation form of the Navier-Stokes equations and utilizes linearization and localization at the boundaries based on these variables. The proposed boundary conditions are applied ...

The generalization of a class of low-dissipative high order filter finite difference methods for long time wave propagation of shock/turbulence/combustion compressible viscous gas dynamic flows to compressible MHD equations for structured curvilinear grids has been achieved. The new scheme is shown to provide a natural and efficient way for the minimization of the divergence of the magnetic fie...

Micellar solutions of polystyrene-block-polybutadiene and polystyrene-block-polyisoprene in propane are found to exhibit significantly lower cloud pressures than the corresponding hypothetical nonmicellar solutions. Such a cloud-pressure reduction indicates the extent to which micelle formation enhances the apparent diblock solubility in near-critical and hence compressible propane. Concentrati...

For every total recursive time bound t, a constant fraction of all compressible (low Kolmogorov complexity) strings is t-bounded incompressible (high time-bounded Kolmogorov complexity); there are uncountably many infinite sequences of which every initial segment of length n is compressible to log n yet t-bounded incompressible below 1 4n − log n; and there are a countably infinite number of re...

The entropy solutions of the compressible Euler equations satisfy a minimum principle for the specific entropy [10]. First order schemes such as Godunov-type and Lax-Friedrichs schemes and the second order kinetic schemes [6] also satisfy a discrete minimum entropy principle. In this paper, we show an extension of the positivity-preserving high order schemes for the compressible Euler equations...
