We present the results from an on-going project financed by the Danish PSO-fund where a number of subjects relevant for further automation and improvement of short term wind power forecasts methods are studied. The technological basis of the project is adaptive forecast methods as the methods forming the basis of WPPT (Wind Power Prediction Tool) – a well proven system for wind power forecastin...

Many kinds of computer vision problems can be formalized as statistical estimation problems with nuisance parameters. In the past, such problems have been solved without making any distinction between the nuisance parameters and structural ones. However, a theory of statistics suggests that eliminating the nuisance parameters by assuming a probability distribution on them improves estimation ac...

This special issue of The European Journal of Control is dedicated to some of the results of the European Community Esprit LTR Project VHS Veri cation of Hybrid Systems It consists of papers dealing with various aspects of one of the case studies treated in the project the Experimental Batch Plant at the university of Dortmund Before presenting the papers themselves it is worthwhile to say some...

The least squares method has been applied to estimate parameters in an aerodynamic model of a simulated aircraft, using data that can be expected to available from sensors on an Unmanned Aerial Vehicle. A combination of two non-linear state observers have been implemented to estimate wind data such as angle of attack, sideslip and dynamic pressure. Simulations have confirmed that the observers ...

This paper proposes a design of a speed control of three phase induction motor fed from wind turbine using genetic algorithm. The wind turbine acts as a prime-mover for doubly fed induction generator. To make the system stable, proper monitoring is required or sometimes an auxiliary system can also be a good option, which can support the primary system during undesirable conditions. The three p...

This study examines manufacturer' perceptions of task and emotional conflict in domestic channels of distribution. Both are expected to depend on three antecedents (centralization, esprit de corps, and communication barriers) and to affect performance relative to competitors and manufacturer's satisfaction directly and indirectly through strategy quality. The results support a positive link bet...
