  1. 1. Active Noise Control with Virtual Reference Signals in an FXLMS Algorithm

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Johan Nygren; [2018]
    Keywords : road noise; active noise control; FXLMS; virtual reference signals; vagbuller; aktiv bullerbekampning; FXLMS; virtuella referenssignaler;

    Abstract : Noise pollution from road traffic is one of the greatest environmental issues in modern day, and the social cost for road traffic noise was estimated to over 16 billion SEK per year in Sweden in2014. Passive or active control methods can be used to reduce the noise. READ MORE

  3. 2. Controlling the Laminar-to-Turbulent Transition in a Fluid Flow

    University essay from KTH/Mekanik

    Author : Sundin Johan; [2015]
    Keywords : ;

    Abstract : Det finns många vardagliga anordningar där en fluid interagerar med en yta. Reduktion av ytfriktion mellan fluiden och ytan kan förbättra verkningsgraden för många av dessa anordningar. Ett typiskt exempel på denna interaktion är flödet över en platt yta. READ MORE

  4. 3. Performance Evaluation of Different Active Noise Control (ANC) Algorithms for Attenuating Noise in a Duct

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Muhammad Moazzam; Muhammad Shoaib Rabbani; [2014]
    Keywords : Active Noise Control; Adaptive Algorithms; L-LMS; N-LMS; FuLMS; RLS; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Abstract : Adaptive filter algorithms are extensively use in active control applications and the availability of low cost powerful digital signal processor (DSP) platforms has opened the way for new applications and further research opportunities in e.g. the active control area. READ MORE

  5. 4. Aktiv reglering av rörelse i ryggmärg

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Martin Bräutigam; Mikael Gustafsson; [2006]
    Keywords : reglering;

    Abstract : Researchers in neurophysiology in Lund have undertaken measurements of the spinal cord in rats where the movement of the spinal cord due to blood flow and breathing has proved to be a major obstacle in their research. Except from manufacturing electrodes specialized for the task, an idea has been to reduce the effect of the motion by moving a table on which the object is placed, in a compensating manner.

  6. 5. Implementation of Adaptive Filter Structures on a Fixed Point Signal Processor for Acoustical Noise Reduction

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Krishna Chaitanya Chunduri; Chalapathi Gutti; [2005]
    Keywords : Noise reducation; Adaptive filter structures; Fixed point procesor;

    Abstract : The problem of controlling the noise level in the environment has been the focus of a tremendous amount of research over the years. Active Noise Cancellation (ANC) is one such approach that has been proposed for reduction of steady state noise. READ MORE
