1. Rotordynamic Analysis with Special Reference to Composite Rotors and Internal Damping
Sammanfattning : The present doctoral thesis is concerned with three different rotordynarnic applications; composite rotors, internal damping and microslip in a turbine generator. When a composite shaft has an imperfection, such as differences in the filament winding angle, the eigenfrequencies of the non-rotating shaft depend only on the material stiffness. LÄS MER
2. Quality of life in patients with malignant blood disorders : a clinical and methodological study
Sammanfattning : The overall aim of this thesis was to evaluate and, improve measurements of, health-related quality of life (HRQL) in patients with malignant blood disorders. Patients undergoing autologous stem cell transplantation (SCT), long-term (>5 years) survivors of Hodgkin's lymphoma (HL) and a randomly selected control group were studied. LÄS MER
3. SAM-tal om bedömning och matematikkunnighet : En studie av lärares tankestilar
Sammanfattning : Inom ramen för svensk grundskola har enskilda lärare varit betrodda med en högre grad av autonomi än lärare i många andra europeiska länder. Exempelvis har lärare givits ett stort ansvar att bedöma och betygssätta elevers kunskaper. LÄS MER

5. Cylindrical Waveguide Slot Antenna Analysis
Sammanfattning : Waveguide slot antennas with longitudinal and transverse slots are analyzed using a rigorous method. The antennas are divided into regions, which are analyzed separately and matched by a moment method procedure. At the apertures between the regions, the electric fields are expanded in trigonometric basis functions. LÄS MER
