  • The introduction of renewable wave energy to the existing power grid

    Creator:
    Ruthruff, William Arthur
    Abstract:
    Wind energy is a cornerstone to the world of renewables. It is widely used in many parts of the world as a clean and effective form of power generation. However, wind power has a number of drawbacks, which limits its use in many regions. Solar power has been used not...

  • Finite element based rotor design optimization for the brushless doubly-fed machine

    Creator:
    Salim, Mohamed Ali, 1968-
    Abstract:
    Brushless Doubly-Fed Machines have potential benefits in variable speed generation and adjustable speed drive applications by combining a robust machine structure with a reduced power converter rating. While recent work has demonstrated feasibility, steady-state performance has not been optimized. The nature of doubly-fed operation causes rotor currents of varying, relatively...

  • Active power filter for the cancellation of harmonic line current distortion

    Creator:
    Merk, Marcel
    Abstract:
    With the increased attention on high efficiency and energy savings, power electronic energy conversion equipment is increasingly incorporated in all levels of the power system. The drawback of such equipment is the generation of nonsinusoidal currents in the power distribution network due to the nonlinear operation. Harmonic currents may distort...

  • Novel power conditioning circuits for piezoelectric micro power generators

    Creator:
    Han, Jifeng
    Abstract:
    Advanced low power devices promote the development of micro power generators (MPGs) to replace the batteries to power them. Due to the trend in decreasing integrated circuit (IC) supply voltages, power supply designers are facing more and more serious challenges. The objective of this research is to design a power...

  • Advanced propulsion systems for linear motion with high performance requirements

    Creator:
    Zhou, Xiaolin
    Abstract:
    Traditionally linear actuator applications are addressed by the use of hydraulic systems. The high maintenance cost and poor reliability will always be the most critical problem in the real applications. Benefited from both the high mechanical advantage of the roll screw and the simple structure of the switched reluctance motor,...

  • The experience of sibling relationships in the voices of children : systemic interviews of dyads following the trauma of sibling incest and its recovery

    Creator:
    Fontana, Lynn A.
    Abstract:
    This qualitative study investigated the sibling relationship as it was described through the voices of the children. Ten sibling dyads (brother-sister or brother-brother) involved in family treatment following the discovery of sibling incest were interviewed. Participants in this study were participants in an outpatient clinic in the Northwest during the...
