In the present work, the Roe, the Steger and Warming, the Van Leer, the Chakravarthy and Osher, the Harten, the Frink, Parikh and Pirzadeh, the Liou and Steffen Jr. and the Radespiel and Kroll schemes are implemented, on a finite volume context and using an upwind structured spatial discretization, to solve the Euler equations in the three-dimensional space. The Roe, the Harten, the Chakravarth...

A scheme for the twedimensional Euler equations that uses flow parameters to determine the direction for upwind-differencing is described. This approach reduces the grid-dependence of conventional schemes. Upwinding at the local flow angle and the local pressure-gradient angle is tested. The upwindbiased fluxes are calculated with Roe's approximate Riemann solver. A centered flux is used for th...

3-rectangulations are spatial representatives of assemblies of boxes into a box. Algorithms to generate various classes of 3-rectangulations are developed. The method is extended to specify the generation of higher-dimensional <2-rectangulations, d > 4. 3-rectangulations I consider the following combinatorial problem: how many arrangements of boxes into a box are there subject to the proviso th...

Rules of Engagement (ROE) are driven by a mix of legal, military, and political factors. These dimensions can interact and overlap in subtle ways and must be carefully crafted to be easy to apply in combat situations without jeopardizing mission outcome and the warfighter’s right to self-defense. Although trial and error may have sufficed in the past, the growing complexity of conflicts and the...

In the present work, the Roe, the Steger and Warming, the Van Leer, the Harten, the Frink, Parikh and Pirzadeh, the Liou and Steffen Jr. and the Radespiel and Kroll schemes are implemented, on a finite volume context and using an upwind and unstructured spatial discretization, to solve the Euler equations in the three-dimensional space. The Roe, the Harten, and the Frink, Parikh and Pirzadeh sc...

This article explores the legal status of abortion in the States if the Supreme Court overrules Roe v. Wade, 410 U.S. 113 (1973), and Doe v. Bolton, 410 U.S. 179 (1973), as modified by Planned Parenthood v. Casey, 505 U.S. 833 (1992). Although an overruling decision eventually could have a significant effect on the legal status of abortion, the immediate impact of such a decision would be far m...

Residual distributions (RD) schemes are a class of of high-resolution finite volume methods for unstructured grids. A key feature of these schemes is that they make use of genuinely multidimensional (approximate) Riemann solvers as opposed to the piecemeal 1D Riemann solvers usually employed by finite volume methods. In 1D, LeVeque and Pelanti [J. Comp. Phys. 172, 572 (2001)] showed that many o...

We investigated contemporary and historical influences on the pattern of genetic diversity of European roe deer (Capreolus capreolus). The study was conducted in northeastern Poland, a zone where vast areas of primeval forests are conserved and where the European roe deer was never driven to extinction. A total of 319 unique samples collected in three sampling areas were genotyped at 16 microsa...

ties. In this paper we investigate the behavior of shock-capturing shocks. Here slowly moving means that the ratio of the methods for slowly moving shocks. It is known that for slowly movshock speed to the maximum wave speed in the domain ing shocks even a first-order scheme, such as the Godunov or Roe is much smaller than one. Several references have reported type methods, will generate downst...
