      Detuning detection in induction motors 

      Rodríguez-Cortés, H.; Hadjicostis, Christoforos N.; Stankovic, A. M. (2004)
      In this article we present a model-based scheme to detect detuned indirect field oriented controllers in current fed induction motors. The detection scheme is based on differential geometric techniques. Numerical simulations ...

      Exciton in an Aharonov-Bohm ring: An exactly soluble interacting mesoscopic system 

      Moulopoulos, Konstantinos; Constantinou, Martha G. (2006)
      A Green's function procedure leads to an exact determination of the energy spectrum and the associated eigenstates of a system of two oppositely charged particles interacting through a contact potential and moving in a ...

      Linear dynamic polarizability and the absorption spectrum of an exciton in a quantum ring in a magnetic field 

      Ghazaryan, A. V.; Djotyan, Anahit P.; Moulopoulos, Konstantinos; Kirakosyan, Albert A. (2011)
      The problem of an electron-hole system interacting through a contact potential and moving in a one-dimensional quantum ring threaded by an Aharonov-Bohm flux is considered, with respect to the system's energetics as well ...
