1. 6. Why so different? - Aspects of voice characteristics in operatic and musical theatre singing : Aspects of voice characteristics in operatic and musical theatre singing

   Författare :Eva Björkner; Anders Askenfelt; Ronald C. Scherer; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; operatic singing; musical theatre singing; voice source; subglottal pressure; flow glottogram; inverse filtering; formant frequencies; amplitude quotient AQ ; Music; Musikvetenskap;

   Sammanfattning : This thesis addresses aspects of voice characteristics in operatic and musical theatre singing. The common aim of the studies was to identify respiratory, phonatory and resonatory characteristics accounting for salient voice timbre differences between singing styles. LÄS MER

3. 7. Generation Reliability for Isolated Power Systems with Solar, Wind and Hydro Generation

   Författare :Jimmy Ehnberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Generation reliability; Isolated power systems; Wind power; Solar power; Renewable energy; Stochastic modelling;

   Sammanfattning : This licentiate thesis deals with reliability issues for small isolated power systems. The focus is on power systems in remote areas based entirely on renewable energy sources. The sources investigated in this thesis are mainly solar and wind power; stochastic models for these energy sources are presented. LÄS MER

4. 8. Magnetic orientation in migratory birds

   Författare :Rachel Muheim; Funktionell zoologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal ecology; Djurekologi; cue-conflict; clock-shift; cue calibration; geomagnetic field; high Arctic latitudes; Emlen funnel; magnetic compass; magnetoreception; navigation; migration; bird; orientation;

   Sammanfattning : My thesis focuses on magnetic orientation in migratory birds, i.e. how they can perceive information from the Earth’s magnetic field and use it for orientation. LÄS MER

5. 9. The character of magnetic records of deformed soft sediments with emphasis on liquefaction structures

   Författare :Guangyu Sun; Nils Axel Mörner; Don Tarling; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetism; sediments; deformation; Earth sciences; Geovetenskap;

   Sammanfattning : In this thesis the characteristics of magnetic records in deformed soft sediments during postglacial time in Sweden are studied. Magnetic records refer in this study to magnetic remanence (NRM and ChRM) and susceptibility, including its anisotropy (AMS). LÄS MER

7. 10. Quantification of skeletal, muscular and kinematics parameters in scoliosis : methodological and clinical studies

   Författare :Khaled Mohamed Diab; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Idiopathic scoliosis; new methods; scoliotic angle; vertebral body volume; intercostal muscle; ultrasonography; ground reaction force; centre of mass; centre of pressure; motor control;

   Sammanfattning : This dissertation presents new methods derived for precise evaluation of a number of anatomical and functional variables of the complex thoracospinal deformity in scoliosis. By consensus the scoliotic angle at the frontal plane is measured on radiographs using the Cobb method. LÄS MER
