6. The exchange of sensible and latent heat over the sea
Sammanfattning : Analysis of the neutral exchange coefficients for latent and sensible heat, CEN and CHN, based on measurements from the Östergarnsholms site in the Baltic Sea has been made. The data set used for the CHN study was based on the very accurate MIUU-instrument. LÄS MER
7. Systematic Design of Linear Feedback Amplifiers
Sammanfattning : This work adds a quantitative description of distortion to the structured design method of negative-feedback amplifiers. It constitutes a power-series representation of the feedback amplifier, which may include dynamic (memory) effects, where the design parameters appear explicitly. LÄS MER
8. Liquid Crystals in Guided Wave Optics
Sammanfattning : Liquid crystals are unique optical materials due to their large effective electrooptic and opto-optic coefficients. Currently, liquid crystals are primarily used in flat-panel dis-plays, but there is also an increasing number of nondisplay applications requiring new types of devices employing materials with unique optical properties.

9. Magnetic resonance imaging with ultrashort echo time as a substitute for X-ray computed tomography
Sammanfattning : Radiotherapy dose calculations have evolved from simple factor based methods performed with pen and paper, into computationally intensive simulations based on Monte Carlo theory and energy deposition kernel convolution.Similarly, in the field of positron emission tomography (PET), attenuation correction, which was originally omitted entirely, is now a crucial component of any PET reconstruction algorithm.

10. Diet in epidemiology : assessment, validity and association with upper respiratory tract infection
Sammanfattning : This thesis covers the evaluation of two new interactive web- and meal-based food frequency questionnaires (FFQ). In addition, it investigates the potential association between dietary intake as well as physical activity and the susceptibility to upper respiratory tract infection (URTI). LÄS MER
