The aim of the thesis is to develop a model, based on well known physical and empirical formulas, to simulate the heat load on a rink of artificially frozen ice. A comparison of the results from this model and the results from other methods to determine heat load of the rink is made. The model calculates the heat load from convection, long wave radiation from the air temperature and from the sky t
This paper proposes methods for automatic tuning of slmple regulators. The methods are robust and they require little apriori knowledge about the process. The paper presents the Ideas behind the methods and analysis. Apart from being useful In themselves, the methods will also give a solution to the longstanding problem of safe Initialization of more sophisticated adaptive controllers.
At the first Nordic meeting for linguists with a research interest in reading and writing, held in Løgumkloster, Denmark, in 1987, we reported on a longitudinal study we had just started. The aim of the study was to find out which kind of linguistic disabilities are the most damaging for the development of reading and writing (Magnusson & Nauclér 1990 a, b). When reading is looked upon as a li
The flow and acoustic fields around a wind turbine are computed using a hybrid method. The flow computations reveal the presence of large-scale structures which are convected downstream without significant decay. The strong interaction between the tip vortices and the wind turbine tower is highlighted. The acoustic computations show that the resulting acoustic near-field is dominated by the bla
