  2. 1. Applied Methods for Blind Speech Enhancement

    Author : Benny Sällberg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Acoustic disturbances influence human speech communication by interfering with the communication process. In the worst case, it is impossible to communicate at all due to these disturbances. Methods that reduce the influence of the disturbances while preserving speech intelligibility are often desired.

  4. 2. Heat-transfer Enhancement for Slurries from Biogas Plants− Properties, processes, and thermal systems

    Author : Jingjing Chen; Xiaoyan Ji; Bona Lu; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat-transfer enhancement; slurry; rheological properties; computational fluid dynamics; twisted tubes; biogas production; Energiteknik; Energy Engineering;

    Abstract :  Biomethane production from renewable residues with anaerobic digestion gains increasing attention as a crucial alternative to petroleum fuels. It has been vigorously developed, but the large amounts of subsidy from the government indicate that the process efficiency needs to be further improved. READ MORE

  5. 3. Enhancement, Extraction, and Visualization of 3D Volume Data

    Author : Qingfen Lin; . Lucas J van Vliet; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Three-dimensional (3D) volume data has become increasingly common with the emergence and wide availability of modern 3D image acquisition techniques. The demand for computerized analysis and visualization techniques is constantly growing to utilize the abundant information embedded in these data.This thesis consists of three parts. READ MORE

  6. 4. Electromyogram Signal Enhancement and Upper-Limb Myoelectric Pattern Recognition

    Author : Sara Abbaspour; Maria Lindén; Christian Antfolk; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

    Abstract : Losing a limb causes difficulties in our daily life. To regain the ability to live an independent life, artificial limbs have been developed. Hand prostheses belong to a group of artificial limbs that can be controlled by the user through the activity of the remnant muscles above the amputation. READ MORE

  7. 5. Signal Separation - II

    Author : Ulf Lindgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local convergence; mutual information; chi square test; signal enhancement; parameter identifiability; source separation; signal separation; algorithms;

    Abstract : Signal separation is a signal processing technique which enables the separation of superimposed signals. There are several practical situations were signal separation can be used, for example in noise reduction for cellular phones subject to background noise. READ MORE
