Measured wind data is one of the key input data for wind farm planning and design. There are always some missing and invalid data in wind measurement, which poses the main challenges for wind energy resources assessment. In this paper, the rules of integrity check and reasonableness check are...

Accurate modelling is crucial in designing an optimum system. Wind speed distribution of selected site, hub height and power output curve of chosen wind turbine, are the main factors which influence the performance of wind turbines, and therefore, these must be properly accounted for during...

An approach to constructing a Pareto front approximation to computationally expensive multiobjective optimization problems is developed. The approximation is constructed as a sub-complex of a Delaunay triangulation of a finite set of Pareto optimal outcomes to the problem. The approach is based...

A discrete method of accuracy O(hm) is constructed to solve the integral equation eigenvalue problem λϕ(x)=∫−11K(x,y)ϕ(y)dy, where K(x, y)=log|x−y| or K(x, y)=|x−y|−α, 0α1, ϕ(x) being the eigenfunction associated with the eigenvalue λ. The method is based first on improving the...

We use a discrete spline quasi-interpolant (abbr. dQI) defined on a bounded interval for the numerical solution of linear Fredholm integral equations of the second kind with a smooth kernel by collocation and a modified Kulkarni's method together with its Sloan's iterated version. We study the...

Under the Maastricht Treaty and the Stability and Growth Pact (SGP) European Union (EU) Member States commit themselves to avoid excessive deficits over 3% of GDP and to pursue the medium-term objective of budgetary positions close to balance or in surplus. The SGP provides also regulation for...
