  2. 16. Musculoskeletal disorders in Swedish military aircrew : screening and clinical examination of the cervico-thoracic region

    Author : Matthias Tegern; Ulrika Aasa; Björn Äng; Karin Harms-Ringdahl; Mari Lundberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Musculoskeletal disorders; Pain; Swedish Armed Forces; aircrew; pilots; physiotherapy; reliability; sjukgymnastik; Physiotherapy;

    Abstract : Musculoskeletal disorders (MSD) are a common and growing occupational problem in military aircrew. Intervention studies attempting to reduce such issues have only showed limited preventive effects. Furthermore, in-depth knowledge of the clinical presentation of aircrew members with painful episodes is lacking. READ MORE

  4. 17. Modelling and Implementation of a vision system for embedded systems

    Author : Per Andersson; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Today more and more functionality is included in embedded systems, resulting in an increased system complexity. existing design methodologies and design tools are not adequate to deal with this increase in complexity. To overcome these limitations application specific design solutions are more common. READ MORE

  5. 18. Remote Measurements of Ship Emissions

    Author : Niklas Berg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; airborne; Ship emissions; sulphur dioxide; nitrogen dioxide; DOAS; in situ measurements; carbon dioxide;

    Abstract : The combustion of sulphur-containing fossil fuels gives rise to emissions of sulphurdioxide. Nitrogen oxides are also emitted when fuels are burned. The InternationalMaritime Organization (IMO) has ratified regulations regarding Sulphur Fuel Content(SFC) and NOx emissions from the shipping sector. READ MORE

  6. 19. Modelling and design approaches of magnetostrictive actuators

    Author : Mattias Oscarsson; Göran Engdahl; Tord Cedell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetostriction; Terfenol; Coil optimisation; Leakage flux; Modelling tools; Eddy currents; Magnetostriktion; Electrical engineering; Elektroteknik;

    Abstract : A magnetostrictive material elongates when it is subjected to a magnetic field. This effect can then be used to design powerful actuators. READ MORE

  7. 20. Algorithms and Library Software for Periodic and Parallel Eigenvalue Reordering and Sylvester-Type Matrix Equations with Condition Estimation

    Author : Robert Granat; Bo Kågström; Isak Jonsson; Volker Mehrmann; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; periodic eigenvalue problems; product eigenvalue problems; periodic Schur form; periodic eigenvalue reordering; periodic eigenspaces; parallel algorithms; Sylvester-type matrix equations; parallel eigenvalue reordering; condition estimation; Computer science; Datavetenskap;

    Abstract : This Thesis contains contributions in two different but closely related subfields of Scientific and Parallel Computing which arise in the context of various eigenvalue problems: periodic and parallel eigenvalue reordering and parallel algorithms for Sylvestertype matrix equations with applications in condition estimation.Many real world phenomena behave periodically, e.
