  3. 2. 3D-printing of undisturbed soil imaged by X-ray

    University essay from SLU/Dept. of Soil and Environment

    Author : Matthias Bacher; [2013]
    Keywords : soil; macropores; 3D-printing; X-ray;

    Abstract : An artificial soil pore network can help to analyse preferential macropore flow which is important for pollutant leaching and degradation in the environment. Reproducing soil macro pores in an artificial, durable material offers the opportunity of repeating experiments in contrast to real soil pore networks. READ MORE

  4. 3. Adaptive Sub band GSC Beam forming using Linear Microphone-Array for Noise Reduction/Speech Enhancement.

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Mamun Ahmed; [2012]
    Keywords : Generalized Side lobe Canceller GSC ; Blocking matrix; Microphone array; Sub band; SNR. ;

    Abstract : This project presents the description, design and the implementation of a 4-channel microphone array that is an adaptive sub-band generalized side lobe canceller (GSC) beam former uses for video conferencing, hands-free telephony etc, in a noisy environment for speech enhancement as well as noise suppression. The side lobe canceller evaluated with both Least Mean Square (LMS) and Normalized Least Mean Square (NLMS) adaptation. READ MORE

  5. 4. Acoustic Beamforming for Hearing Aids Using Multi Microphone Array by Designing Graphical User Interface

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : S S V SUMANTH KOTTA; BULLI KOTESWARARAO KOMMINENI; [2011]
    Keywords : Acoustic Beamforming; Array signal processing; Beam steering; Direction of arrival estimation; Distortion measurement; Interference cancellation; Microphone arrays; Noise cancellation; Speech enhancement.;

    Abstract : Hearing impaired persons lose their ability to distinguish speech signal in ambient noise. Human hearing system is sensitive to interfering noise. Interfering noise decreases the quality and intelligibility of the speech signal which in turn makes speech communication default. READ MORE
