  4. 3. Lexical and Acoustic Modelling of Swedish Prosody

    Författare :Johan Frid; Fonetik; []
    Nyckelord :HUMANIORA; HUMANITIES; phonology; Phonetics; stress; dialects; Swedish; word accents; letter-to-sound; text-to-speech; modelling; intonation; prosody; speech technology; Fonetik; fonologi; Scandinavian languages and literature; Nordiska språk språk och litteratur ;

    Sammanfattning : Prosody and intonation are very important ingredients of human speech. In speech technology, text-to-speech (TTS) and automatic speech recognition (ASR) systems must incorporate prosodic models in order to reach acceptable performances. LÄS MER

  5. 4. On millimeter and submillimeter wave focal plane arrays implemented with MEMS waveguide switches

    Författare :Henrik Frid; Joachim Oberhammer; Vessen Vassilev; Mikro- och nanosystemteknik KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Extended Hemispherical Lens; Beam Steering; Focal Plane Array FPA ; Ray-Tracing; RF MEMS; waveguide switch; micromachined waveguide; submillimeter-wave; rectangular waveguide; terahertz; lenses; antenna theory; silicon; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : This thesis presents research towards enabling micromachined millimeter and submillimeter wave focal plane arrays (FPAs). The FPAs operate under the following principle: a switch network consisting of microelectromechanical (MEMS) switches, integrated with micromachined waveguides, is used to feed an array of antenna elements, located in the focal plane of a high-gain quasi-optical system.

  7. 5. Children with Down syndrome - : an epidemiological study with special focus on congenital heart defects

    Författare :Christina Frid; Jens Schollin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Down syndrome; congenital malformations; mortality; morbidity; neonatal data; congenital heart defect; atrioventricular septal defect; operation; gender; Pediatrik; Paediatric medicine; Pediatrisk medicin; pediatrik; Pediatrics;

    Sammanfattning : To assess the impact of congenital malformations in Down syndrome (DS) on morbidity, mortality and outcome at birth, information on all children with DS born in the northern part of Sweden in 1973-80 (n=211) and 1995-98 (n=88) was collected. Most common were congenital heart defects (CHD), dominated by atrioventricular septal defects (AVSD). LÄS MER
