21. Recognition and Evaluation by Video Synthesis Methods and Symmetry Features
Sammanfattning : Biometrics is being increasingly utilized for person authentication. It requires little or no efforts from the user as compared to traditional non-biometric systems where the user has to memorize PIN codes and passwords or carry pass cards and keys that can be easily forgotten or lost.

22. Capillary electrophoresis and multivariate calibration in the analysis of natural waters
Sammanfattning : The aim of this work was to explore the applicability of capillary zone electrophoresis (CZE) and multivariate partial least squares (PLS) regression in the analysis of organic compounds and inorganic ions in natural waters. A new CZE application was developed to analyze low molecular weight (LMW) organic acids. LÄS MER
23. An Approach on Material Model Calibration for Modelling of Sheet Metal Deformation and Failure
Sammanfattning : Sheet metals are often used in automotive and aerospace applications for safety-relevant components. Weight reduction is one possibility to reduce fuel consumption or increase the payload capacity and therewith reduce the carbondioxide emission of these trans-portation vehicles. LÄS MER
24. Planar-Goubau-line components for terahertz applications
Sammanfattning : Terahertz-wave technology has a broad range of applications, including radio astronomy, telecommunications, security, medical applications, pharmaceutical quality control, and biological sensing. However, the sources, detectors, and components are less efficient at this frequency band due to parasitic effects and increased total losses, which hinder the performance of terahertz systems.

25. Hyperspectral imaging for in-situ applications : Methods to improve the classification of materials using hyperspectral imaging
Sammanfattning : This thesis addresses several research questions related to in-situ hyperspectral imaging systems, proposes measurement methods for more accurate imaging, and examines the impact of the methods on material classification.First, the thesis investigates the possibility of successfully calibrating a hyperspectral imaging system using a low-cost PTFE reference.
