    Aeroacoustic Prediction of Jet and Slat Noise

    The flow field and the acoustic field of various jet flows and a high-lift configuration consisting of a deployed slat and a main wing are numerically analyzed. The flow data, which are computed via large-eddy...

    On Poljak's improved subgradient method

    Poljak has suggested an improved subgradient method and provided a lower bound on the improvement of the Euclidean distance to an optimal solution. In this paper, we provide a stronger lower bound and show tha...
