  3. 2. Extraction of Loudspeaker- and room impulse responses under overlapping conditions

    University essay from Uppsala universitet/Signaler och system

    Author : Felix Gustafsson; [2022]
    Keywords : Signal processing; Optimization; Acoustics; Dereverberation; Sparse deconvolution; Multipath propagation;

    Abstract : A loudspeaker is often considered to be a Linear Time Invariant (LTI) system, which can be completely categorized by its impulse response. What sets loudspeakers apart from other LTI-systems is the acoustical aspect including echoes, which makes it a lot harder to take accurate noise free measurements compared to other LTI-systems such as a simple RC circuit.

    Abstract : This project has been carried out on the behalf of Ihus in collaboration with Stuns Energi. The goal was to find and model a solution based on the process of pyrolysis that can deliver enough heat to Almunge fire station while storing maximum amount of CO2 in the form of biochar. READ MORE

  5. 4. VIBRATION ANALYSIS OF THE FLUE GAS FAN IN MÄLARENERGI’S UNIT 6 : Troubleshooting using CFD simulations in ANSYS to locate the origin of the vibration spikes and suggest solutions for a more optimized performance

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Felix Brogren; Peter Gustafsson; [2018]
    Keywords : Troubleshoot; CFD simulation; spectrum analysis; flow-induced vibration; vibrations in machinery; Felsökning; CFD-simulering; spektrum analys; flödesinducerad vibration; vibrationer i maskiner;

    Abstract : The purpose of this study is to investigate the flue gas fan in Mälarenergi’s Unit 6 and try to find what is causing the vibrations increase. The Fast Fourier transform (FFT) method was used for this degree project. A comparison was made with previous studies using FFT in order to pinpoint the source of the problem with vibrations.
