    • Energy and mass of 3D and 2D polarons in the overall range of the electron-phonon coupling strength 

      Ercelebi, A.; Senger, R. T. (Institute of Physics Publishing Ltd., 1994)
      The ground-state characterization of the polaron problem is retrieved within the framework of a variational scheme proposed previously by Devreese et al for the bound polaron. The formulation is based on the standard ...

    • Parameter identification for partially observed diffusions 

      Dabbous, T.E.; Ahmed, N.U. (Kluwer Academic Publishers-Plenum Publishers, 1992)
      In this paper, we consider the identification problem of drift and dispersion parameters for a class of partially observed systems governed by Ito equations. Using the pathwise description of the Zakai equation, we formulate ...

    • Scheduling to minimize the coefficient of variation 

      De, P.; Ghosh, J. B.; Wells, C. E. (Elsevier, 1996)
      In this paper, we address the problem of uninterruptedly scheduling a set of independent jobs that are ready at time zero with the objective of minimizing the coefficient of variation (CV) of their completion times. We ...
