1. DNA Analysis of PCR-Inhibitory Forensic Samples
Sammanfattning : DNA evidence, linking perpetrators to crime scenes, is central to many legal proceedings. However, crime scene samples often contain extraneous substances that may interfere with the PCR-based forensic analysis, resulting in partial or negative DNA profiles. Extensive DNA purification may remove inhibitors, but involves the risk of DNA loss. LÄS MER
2. Aspects of common principal components
Sammanfattning : The focus of this thesis is the common principal component (CPC) model, the generalization of principal components to several populations. Common principal components refer to a group of multidimensional datasets such that their inner products share the same eigenvectors and are therefore simultaneously diagonalized by a common decorrelator matrix.

3. Very low bitrate facial video coding : based on principal component analysis
Sammanfattning : This thesis introduces a coding scheme for very low bitrate video coding through the aid of principal component analysis. Principal information of the facial mimic for a person can be extracted and stored in an Eigenspace. Entire video frames of this persons face can then be compressed with the Eigenspace to only a few projection coefficients. LÄS MER
4. Valuing environmental benefits using the contingent valuation method : an econometric analysis
Sammanfattning : The purpose of this study is to investigate methods for assessing the value people place on preserving our natural environments and resources. It focuses on the contingent valuation method, which is a method for directly asking people about their preferences. LÄS MER
5. A Composable and Extensible Environment for Equation-based Modeling and Simulation of Variable Structured Systems in Modelica
Sammanfattning : Modeling and Simulation are usually used to solve real-world problems safely and efficiently by constructing digital models of Cyber-Physical Systems. The models can be simulated and analyzed with respect to requirements, and decisions about their design can be based on this analysis. LÄS MER
