Predictive velocity control in a hilly terrain over a long look-ahead horizon

Computationally Efficient Long Horizon Model Predictive Direct Current ‎Control of DFIG Wind Turbines ‎

Model predictive control (MPC) based methods are gaining more and more attention in power converters and electrical drives. Nevertheless, high computational burden of MPC is an obstacle for its application, especially when the prediction horizon increases extends. At the same time, increasing the prediction horizon leads to a superior response. In this paper, a long horizon MPC is proposed to c...

Route Choice in Hilly Terrain

The orienteering route choice problem involves finding the fastest route between two given points, with running speed determined by various properties of the terrain. In this study we consider only the effect of climbing or descent on running speed. If a runner’s pace p (the reciprocal of running speed) varies linearly with gradient m, the straight-line route is always fastest. This may be a re...

Numerical Prediction of the Wind Flow over Real Hilly Terrain

In the present paper, a numerical prediction of the wind flow in a neutrally-stratified atmosphere over real hilly terrain is presented. For the solutions of the NavierStokes equations which are the governing equations of a microscale atmospheric flow, a numerical model based on the finite-volume formulation in a boundary-fitted coordinate system and the SIMPLEC pressure-correction algorithm is...

A look back and a look ahead.

The author reviews a series of predictions made more than two decades ago regarding nursing and nursing administration. These concerned the work of nursing, the workers involved in nursing, the environment surrounding practice, and the nurse's role. While many of the forecasts were right on target, others fell short of the mark; both are discussed in light of the challenges facing nurse adminis...
