    Energetics and phase diagrams of Fe-Cr and Co-Cr systems from first principles by Vreštzál J., Houserová J., Šob M.

    Published 2002-01-01
    “…The structural energy differences, calculated by FLAPW (Full potential augmented plane wave) method, enable us to utilize a more complete physical information about total energy of intermetallic phases and to propose a new model for their thermodynamic description. Our approach is based on the two-sublattice model, similarly as for solid solution phases, but the structural energy differences for end-members in the metastable or unstable structures are obtained by means of first-principles electronic structure calculations. …”

    Correcting Fast-Mode Pressure Errors in Storm-Scale Ensemble Kalman Filter Analyses by Corey K. Potvin, Louis J. Wicker

    Published 2013-01-01
    “…When the EnKF is used to research storm-scale dynamics, the resulting spurious pressure oscillations are large enough to impact investigation of processes driven by nonhydrostatic pressure gradient forces. Fortunately, thermodynamic retrieval techniques traditionally applied to dual-Doppler wind analyses can be adapted to diagnose the balanced portion of an EnKF pressure analysis, thereby eliminating the fast-mode pressure oscillations. …”
