The present paper is a study of one impersonator and one of his voice imitations in order to find out how he changes his own voice and speech behaviour in order to get close to the target voice. Preliminary results from the auditory and the acoustic analysis, focusing on speech style and intonation pattern, will be presented.
A new reactor type has been designed by Alfa Laval AB,the open plate reactor (OPR). It combines good mixing with high heat transfer capacity. With the new open plate reactor, highly exothermic reactions can be produced using more concentrated reactants. In the paper, the reactor type is presented and a model from first principles is derived. The paper concerns the control properties of the platere
Stationary solar energy concentrators are a promising option for decreasing the price of photovoltaic electricity. This thesis studies stationary concentrators in PV/Thermal applications. The studied systems are parabolic troughs intended for building integration. The first chapters briefly explain the optics of solar energy concentrators. The theoretical maximum concentration ratios of two and th
