For aeroacoustics problems, the nonlinear Euler equations are often written in primitive variables in which the pressure is treated as a solution variable. In this paper, absorbing boundary conditions based on the Perfectly Matched Layer (PML) technique are presented for nonlinear Euler equations in

Recently, perfectly matched layer (PML) as an absorbing boundary condition has found widespread applications. The idea was first introduced by Berenger for electromagnetic waves computations. In this paper, it is shown that the PML equations for the linearized Euler equations support unstable soluti
In this paper, which is a continuation of previous work (Part VI), two series of dipepticles, one with leucine and the other with isoleucine as the N-terminal residue, have been examined by both ion-exchange and thin-layer chromatography. The possibility of identifying these compounds in biological
