Moderne Systeme sehen meist alt aus - Neue Perspektiven für Legacy-Anwendungen

An einem konkreten Beispiel der Anbindung eines über Jahrzehnte hinweg gewachsenen Zulieferer-Systemes an ein modernes E-Commerce System (Online Shop), soll das Integrationsmuster der dateibasierten Integration unter Verwendung des IBM WebSphere Message Broker vorgestellt werden. Dabei wird ein besonderer Augenmerk auf die Konstruktion einer einfachen nachrichtenbasierten Integrationslösung für...

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...
