   Sammanfattning : Today the immunosuppressive treatment is kept to a level were the incidence of acute rejection is below 20% within the first year after transplantation. As a consequence, a group of transplanted patients is over-immunosuppressed and at risk for infections. LÄS MER

3. 2. Articulatory-Acoustic Relationships in Swedish Vowel Sounds

   Författare :Christine Ericsdotter; Olle Engstrand; Björn Lindblom; Peter Ladefoged; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Swedish vowels; articulatory modelling; MRI; Phonetics; Fonetik;

   Sammanfattning : The goal of this work was to evaluate the performance of a classical method for predicting vocal tract cross-sectional areas from cross-distances, to be implemented in speaker-specific articulatory modelling. The data forming the basis of the evaluation were magnetic resonance images from the vocal tract combined with simultaneous audio and video recordings. LÄS MER

4. 3. Effects of peripheral auditory adaptation on the discrimination of speech sounds

   Författare :Francisco Lacerda; Hartmut Traunmüller; Olle Engstrand; Björn Lindblom; Louis Pols; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Adaptation; discrimination; categorical perception; Phonetics; Fonetik; Phonetics; fonetik;

   Sammanfattning : This study investigates perceptual effects of discharge rate adaptation in the auditory-nerve fibers. Discrimination tests showed that brief synthetic stimuli with stationary formants and periodic source were better discriminated when they had an abrupt as opposed to a gradual onset (non-adapted vs adapted condition).

5. 4. En perceptuell och akustisk studie av svenskans koronaler i ett dialektperspektiv

   Författare :Peder Livijn; Anders Eriksson; Olle Engstrand; Frank Kügler; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Swedish; Dialect; Typology; Perceptual discrimination; Acoustical measurements; Phonetics; Fonetik; Phonetics; fonetik;

   Sammanfattning : The purpose of this dissertation is to contribute to a typology of the Swedish language as it was spoken in the entire Swedish speaking area around the year 2000. Specifically, the plan is to base this typology solely on different pronunciations of the four coronal consonants /t, d, n/ and /l/. LÄS MER
