  1. 1. Long-Term Simulation of Coastal Evolution

    Författare :Hoan Le Xuan; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tidal inlet; inlet shoal; sediment transport; spit growth; shoreline change; spit model; inlet model; mathematical model; numerical model; shoreline model;

    Sammanfattning : There is a strong relationship between regional sediment transport and the local processes at tidal inlets and around coastal structures. Many coastal projects require quantitative understanding of these processes and the interactions between them. LÄS MER

  3. 2. Transmission loss of vehicle seals

    Författare :Qi Li; Leping Feng; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle seals; reverberation room test; contact analysis; simple model; mass law; FEM analysis; distorted circular duct model; Acoustics; Akustik;

    Sammanfattning : Sound transmission loss of vehicle seals was studied in this thesis. Reverberation room test and semi-anechoic chamber test were respectively studied. LÄS MER

  4. 3. Towards community-based injury prevention : the Motala model

    Författare :Kent Lindqvist; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : In the Swedish County of Östergötland a comprehensive health policyprogramme including accidents was decided by the health authorities in 1988. An accident prevention programme (the "Motala Accident Prevention Study") had already started with an epidemiological analysis of accidents in the community. LÄS MER

  5. 4. Functioning and disability in adults with hearing loss : the preparatory studies in the ICF Core sets for hearing loss project

    Författare :Sarah Granberg; Berth Danermark; Kerstin Möller; Claes Möller; Jerome Bickenbach; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hearing loss; adults; ICF; classification; functioning; disability; linking; Handikappvetenskap; Disability Science;

    Sammanfattning : Hearing loss (HL) is a health condition that affects more than 360 million people worldwide. The findings from previous research point at the adverse relationship between adults with hearing loss and important aspects of everyday life such as social relations, communication and work-related tasks.

  7. 5. A lumped element transformer model including core losses and winding impedances

    Författare :David Ribbenfjärd; Göran Engdahl; Arvid Broddefalk; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power transformer; hysteresis; dynamic hysteresis; eddy currents; excess eddy currents; leakage flux; winding model; core model; magnetic measurements; magnetic materials; Electrical engineering; Elektroteknik;

    Sammanfattning : In order to design a power transformer it is important to understand its internal electromagnetic behaviour. That can be obtained by measurements on physical transformers, analytical expressions and computer simulations. LÄS MER
