  1. 1. New Variants of Nonnegative Matrix Factorization with Application to Speech Coding and Speech Enhancement

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Pedro Jafeth Villasana Tinajero; [2019]
    Nyckelord :;

    Sammanfattning : In this thesis, new variants of nonnegative matrix factorization (NMF) based ona convolutional data model, -divergence and sparsication are developed andanalyzed. These NMF variants are collectively referred to as -CNMF. Commonsparsication techniques such as L1-norm minimization and elastic net arediscussed and a new regularizer is proposed. LÄS MER

  2. 2. Beamforming and Blind Signal Separation for Far-field Voice Capture using a Microphone Array

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Luke Postema; Johan Davidsson; [2019]
    Nyckelord :Beamforming; Microphone array; Minimum variance distortionless response; delay-and-sum; direction of arrival; blind signal separation; Technology and Engineering;

    Sammanfattning : With the evolving technology of mobile electronics and other forms of communication methods, an increasing demand of speech intelligibility is introduced. In a conference room for example, multiple microphones are placed directly in front of the speaker in order to pick up clean speech. However, several challenges still exist. LÄS MER

  3. 3. Study of tomato fiber fragmentation in the high-pressure homogenizer

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Maytham Al-Ameri; [2019]
    Nyckelord :food engineering; livsmedelsteknik; Technology and Engineering;

    Sammanfattning : Homogenization is commonly used in many food processes in which products pass through a narrow gap causing break down of large particles into smaller one thereby reducing creaming and sedimentation of the products. This study aims to investigate fragmentation of tomato fibers and test which breaking mechanisms are dominating in a high-pressure homogenizer. LÄS MER

  4. 4. Källsortering i Halmstad: En studie om vad som kan få fler invånare att sortera sitt avfall

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap; Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Cecilia Claesson; Emmy Isbring; [2019]
    Nyckelord :avfallshantering; avfallsplan; Halmstad; hushållsavfall; källsortering; matavfall; optisk sortering;

    Sammanfattning : In the residual waste bags in the municipality of Halmstad, only 28% of the waste was sorted correctly according to the pick analysis from spring 2018. In the municipality's new waste plan from 2019, one of the objectives is that this number should be 75% in 2025. LÄS MER

  5. 5. En annorlunda salongsbildning : Den borgerliga kvinnans bildning utifrån Magasin för konst, nyheter och moder (1818-1844).

    Kandidat-uppsats, Uppsala universitet/Institutionen för idé- och lärdomshistoria

    Författare :Emma Forsberg; [2018]
    Nyckelord :Separate Spheres; Womens studies; education; 19th century; The cult of true womanhood; Gender.;

    Sammanfattning : The history of women education has been structured by two powerful narratives. The first of these is the tale of the separation of the spheres and the second is the application of the cult of true womanhood to understand women place in the early 19th century. LÄS MER
