Study on Mach Reflection and Mach Configuration

Shock reflection is a fundamental phenomenon in studying compressible flow. Since Ernst Mach first studied the reflection phenomena of shock waves in 1878 [6] great amount of research works on such phenomena, mainly experiments and computations, was proceeded. In gas dynamics when a shock wave meets an obstacle in its propagation process the shock reflection occurs generally. There are various ...

Low Mach

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...

Assuring Distributed Trusted Mach

The Distributed Trusted Mach (DTMach) program is developing a design for a high-assurance, secure, distributed system based on Mach. To achieve this goal, it is rst necessary to identify the general threats against which DTMach must protect. The next step is to identify control mechanisms that are suucient to protect against each of the threats. The DTMach design makes extensive use of type enf...

Mach–Zehnder–Fano interferometer

We introduce a concept of the Mach–Zehnder–Fano interferometer by inserting a cavity exhibiting Fano resonance into a conventional interferometer. By employing the scattering-matrix approach, we demonstrate that the transmission becomes sensitive to a position of the cavity such that an asymmetric structure exhibits a series of narrow resonances with almost perfect reflection. We discuss how to...
