1. 11. Muscle composition, reach, physical activity and botulinum toxin treatment in children with cerebral palsy

   Författare :Stefan Gantelius; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Cerebral palsy (CP), the most common cause of movement disorders and physical disability in children all over the world, is caused by an injury to the developing brain. Although this injury is not progressive, the manifestations of the disorder change as the child ages. LÄS MER

3. 12. Physical Activity among Adolescents in a Swedish Multicultural Area : An Empowerment-Based Health Promotion School Intervention

   Författare :Andreas Fröberg; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Accelerometer; Adolescents; Empowerment; Health promotion; Intervention; Participatory; Physical activity; School; Shared decision making; Socioeconomic;

   Sammanfattning : The overarching aim of the present thesis was two-fold. The first aim was to describe and critically reflect upon the experiences of developing and implementing an empowerment-based school intervention, focusing on food and physical activity, involving adolescents from a Swedish multicultural area characterized by low socioeconomic status.

4. 13. Non-contact surface wave measurements on pavements

   Författare :Henrik Bjurström; Nils Rydén; Björn Birgisson; Jinying Zhu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; seismic testing; asphalt concrete; dynamic modulus; non-contact measurements; rolling measurements; surface waves; Lamb waves; MEMS microphones; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : In this thesis, nondestructive surface wave measurements are presented for characterization of dynamic modulus and layer thickness on different pavements and cement concrete slabs. Air-coupled microphones enable rapid data acquisition without physical contact with the pavement surface. LÄS MER

5. 14. Real-time signal processing in MEMS sensor-based motion analysis systems

   Författare :Jiaying Du; Maria Lindén; Helena Grip; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

   Sammanfattning : This PhD thesis focuses on real-time signal processing for hardware-limited micro-electro-mechanical system (MEMS) sensor-based human motion analysis systems. The aim of the thesis is to improve the signal quality of MEMS gyroscopes and accelerometers by minimizing the effects of signal errors, considering the hardware limitations and the users' perception.
