2. Multi-element analysis of environmental samples using LA-ICP-MS : method developments with emphasis on calibration strategies
Sammanfattning : Analytical applications based on the use of laser ablation-inductively coupled plasma-sector field mass spectrometry (LA-ICP-SFMS) have shown great potential for both quantitative and qualitative determination of elements in a variety of materials, although the weak point is finding a suitable calibration approach. The major focus of this work has, therefore, been internal standardisation and calibration. LÄS MER
3. Characterization and Correction of Analog-to-Digital Converters
Sammanfattning : Denna avhandling behandlar analog-digitalomvandling. I synnerhet behandlas postkorrektion av analog-digitalomvandlare (A/D-omvandlare). A/D-omvandlare är i praktiken behäftade med vissa fel som i sin tur ger upphov till distorsion i omvandlarens utsignal. LÄS MER
4. Subspace Selection Techniques for Classification Problems
Sammanfattning : The main topic of this thesis is linear subspaces for regression - how to find the subspaces and how to evaluate them. The motivation to do regression in a subspace is numerical as well as computational - numerical in the sense that the subspace can filter out the relevant components or features of the problem, computationally in the sense that this filtering can be done quickly and then can nonlinear predictionby artificial neural networks, for instance, be conducted in lower dimensionality.

5. Development of Preprocessing Methods for Multivariate Sensor Data
Sammanfattning : In this work various aspects of data preprocessing are discussed. Preprocessing of data from multivariate sensor data systems is often necessary to extract relevant information or remove disturbances. Depending on the sensor type different preprocessing techniques have to be used. A number of important problems face the user e. LÄS MER
