1. Towards Asymptotic Vector Quantization
Sammanfattning : We study topics in source coding, and vector quantization (VQ) in particular. We approach VQ from two directions: a theoretical starting point based on high rate quantization theory, and a practical based on a database desription of the signal source. LÄS MER
2. Improving accuracy of in situ gamma-ray spectrometry
Sammanfattning : Gamma-ray spectrometry measurements performed on site, or “in situ”, is a widely used and powerful method that can be employed both to identify and quantify ground deposited radionuclides. The purpose of this thesis is to improve the calibration of high purity germanium (HPGe) detectors for in situ measurements, and calculate the combined uncertainty and potential systematic effects.

3. In situ remediation of contaminated sediments using thin-layer capping : effectiveness in contaminant retention and ecological implications
Sammanfattning : Hydrophobic organic contaminants (HOCs) often reside in sediment sorbed to particles, most tightly to particles with high content of organic carbon. If persistent, such pollutants can accumulate in the sediment for many years and constitute a contamination risk for sediment-living organisms and organisms at higher trophic levels, including humans.

4. Metabolic Control, Morbidity and Mortality in Type 1 Diabetes with Onset in Childhood/Adolescence
Sammanfattning : Aim: The overall aim of this thesis was to study mortality in individuals with onset of type 1 diabetes (T1D) in childhood and adolescence in Sweden, related to clinical characteristics such as metabolic control in childhood/adolescence and comorbidity. Methods: All studies in this thesis were register-based observational studies using a nationwide and population-based quality register, the paediatric part of the Swe-dish National Diabetes Register (NDR), for identification and collection of clinical data of individuals with T1D diagnosed before 18 years of age.

5. Kritikens ordning : Svenska bokrecensioner 1906, 1956, 2006
Sammanfattning : The topic of this thesis is book reviewing in Sweden with a focus on three years: 1906, 1956 and 2006. By describing and analysing the critical reception of literature in these periods, the thesis aims to increase the knowledge and understanding of literary critical discourse and the function and power of the literary review in the past and today.
