    Can A Less Boring ECB Remain Accountable?

    Through Bruegel's role on the Monetary Experts Panel for the European Parliament's Committee on Economic and Monetary Affairs, Bruegel scholars contributed to the Committee's Monetary Dialogue with the European Central Bank meeting on 28 September. In this briefing paper for the Panel, Director Jean Pisani-Ferry and Resident Fellow Jakob von Weizsäcker point out that, in the wake of the financial crisis, the ECB will take on much more responsibility for macro-prudential supervision of the financial system. With this added responsibility, however, comes serious questions about the mechanisms in place to ensure the ECB's accountability. Previously focused almost solely on price stability, the ECB will now likely be asked to increase its discretionary decision-making, especially in dealing with financial regulation. The accompanying accountability questions, the authors say, need to be addressed proactively.

    Laboratory studies of the interaction of ions with condensed gases: Planetary applications

    Get PDF
    The work described is concerned with laboratory studies of the processes that produce the ejection of molecules from the surfaces of condensed gas solids, the change in the chemistry of the surface materials, and the relationship of these results to processes occurring in the solar system. Included is a discussion of the experimental techniques employed in making these laboratory measurements

    Analytical stability models for turning and boring operations

    In this paper an analytical model for stability limit predictions in turning and boring operations is proposed. The multi-dimensional model includes the 3D geometry of the processes. In addition a model for the chip thickness at the insert nose radius is also proposed to observe the effect of the insert nose radius on the chatter stability limit. Chatter experiments are conducted for both turning and boring in order to compare with analytical results and good agreement is observed

    Vertical boring mill capacity is increased
