  1. 11. Blind equalization using third-order moments

    Författare :Patrik Pääjärvi; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : The use of third-order moments in blind linear equalization has been studied with emphasis on their performance in on-line methods of low complexity. Blind equalization has widespread use in areas such as digital communications, acoustics, geophysical exploration, image processing and general measurement problems. LÄS MER

  3. 12. Applied Methods for Blind Speech Enhancement

    Författare :Benny Sällberg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : 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. 13. Retinal function in deaf-blind syndromes

    Författare :Eva Malm; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; general anesthesia.; molecular genetics; hearing impairment; full-field electroretinography; Retinal degeneration;

    Sammanfattning : A variety of disorders can cause retinal degeneration and hearing impairment, and it is of great value to have an early diagnosis since there is a large variation in phenotype and prognosis both within and between the different disorders. The general aim of this thesis was to characterize the retinal function, to describe the phenotype, and – where appropriate – to relate the phenotype to genotype in patients with combined visual and hearing impairment.

  5. 14. Adaptive blind deconvolution using third-order moments : exploiting asymmetry

    Författare :Patrik Pääjärvi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : This thesis focuses on the use of third-order statistics in adaptive blind deconvolution of asymmetric impulsive signals. Traditional methods are typically based on fourthorder moments, which can discriminate signals with heavy-tailed probability functions (i.e. `spiky' signals) from corresponding filtered versions.

  7. 15. Kierkegaard och sociologins blinda fläck

    Författare :Lambros Roumbanis; Lars Udehn; Thora Margareta Bertilsson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; the single individual; freedom; authenticity; anxiety; choice; faith; ethics; subjective truth; Kierkegaard; situation; everyday life; responsibility; meaning; social interaction; sociological theory; objectivity; history; Sartre; the pratico-inert field; seriality; objectified matter; Sociology; Sociologi; Sociology; sociologi;

    Sammanfattning : The overall aim of this dissertation is to discuss the scope as well as the limits of sociological theory. This project is undertaken with the help of Søren Kierkegaard and his unique interpretation of human existence. LÄS MER
