We introduce continuous tools to study the low Mach number behavior of the Godunov scheme applied to the linear wave equation with porosity on cartesian meshes. More precisely, we extend the Hodge decomposition to a weighted L space in the continuous case and we study the properties of the modified equation associated to this Godunov scheme. This allows to partly explain the inaccuracy of the G...

This paper is devoted to the low Mach number limit of weak solutions to the compressible Navier-Stokes equations for isentropic uids in the whole space R d (d = 2 or 3). This problem was investigated by P.L. Lions and N. Masmoudi 19]. We present here a diierent approach based upon Strichartz' estimates for the linear wave equation like in 21] in the inviscid case, which improves the convergence...

This article presents the development of an inclinometer device based on a Mach-Zehnder interferometer considering effects caused by temperature variations. It was demonstrated operation LPG-taper system for angle measurements. The practical results satisfactorily show reliable inclination measures, even with cross sensibility effect variable temperature.

Associations of Machiavellianism (Mach) with self-report and performance emotional intelligence (EI) and with personality were examined. The possible existence of an emotional manipulation capability, not covered within current EI measures, was also examined by constructing an emotional manipulation scale. Mach was found to be negatively correlated with self-report and performance EI, and also ...

in this study, aerodynamic characteristics of a circular cylinder in an axial flow have been investigated numerically and experimentally. the model has been considered as a cylinder with truncated nose and fineness ratio of 3 (length to diameter ratio of 3). the investigation involves a series of wind tunnel measurements, flow visualization, and numerical simulation. we used different mach numb...

The main purpose of this paper is to give a survey of recent development on a classification of soliton solutions of the KP equation. The paper is self-contained, and we give a complete proof for the theorems needed for the classification. The classification is based on the Schubert decomposition of the real Grassmann manifold, Gr(N, M), the set of N -dimensional subspaces in RM . Each soliton ...

[1] We study how heterogeneous rupture propagation affects the coherence of shear and Rayleigh Mach wavefronts radiated by supershear earthquakes. We address this question using numerical simulations of ruptures on a planar, vertical strike‐slip fault embedded in a three‐dimensional, homogeneous, linear elastic half‐space. Ruptures propagate spontaneously in accordance with a linear slip‐weaken...

Mach is a multiprocessor operating system kernel and environment under development at Carnegie Mellon University. Mach provides a new foundation for UNIX development that spans networks of uniprocessors and multiprocessors. This paper describes Mach and the motivations that led to its design. Also described are some of the details of its implementation and current status.

The Mach I O system represents a radical departure from its predecessor Mach which relied on the BSD Unix model of device management The I O interface in Mach sup ports device drivers that are largely device independent implemented at user level and location independent Our approach to device management signi cantly reduces the size of the kernel s machine dependent code enables us to reduce th...
