    Abstract : It is important to know the heat generated due to nuclear decay in the final repository for spent nuclear fuel. In Sweden, the heating powers generated in spent nuclear fuels are currently measured in the calorimeter System 251 at the Clab facility, Oskarshamn. READ MORE

  3. 2. Sensor Array Optimization for Multiple Harmonic Sound Source Separation and DOA

    University essay from Lunds universitet/Teknisk akustik

    Author : Elisabet Suárez Lopéz; [2013]
    Keywords : Technology and Engineering;

    Abstract : INTRODUCTION In the last years a lot of researches about source separation have been realized, like extraction of a signal of interest (vocal recognition application), identification of which source gives which sound (motor engine applications) or noise source characterization (environmental application). Most of these techniques for sound source estimation use the signal-subspace approach, where the number of emitting sources is determined by the multiplicity of the lowest eigenvalue of the correlation matrix.
