16. Multivariate spectroscopic methods for the analysis of solutions
Sammanfattning : In this thesis some multivariate spectroscopic methods for the analysis of solutions are proposed. Spectroscopy and multivariate data analysis form a powerful combination for obtaining both quantitative and qualitative information and it is shown how spectroscopic techniques in combination with chemometric data evaluation can be used to obtain rapid, simple and efficient analytical methods.

17. Multivariate Measurements and Chemical Imaging of Organic Compounds
Sammanfattning : Chemical imaging is an emerging analytical technique, based on the interplay between, most often, spectroscopic measurements and advanced evaluation methodology. With this we can study the distribution of chemical compounds in different compartments, such as individual cells and pharmaceutical tablets. LÄS MER
18. Multivariate Aspects of Phylogenetic Comparative Methods
Sammanfattning : his thesis concerns multivariate phylogenetic comparative methods. We investigate two aspects of them. The first is the bias caused by measurement error in regression studies of comparative data. We calculate the formula for the bias and show how to correct for it. LÄS MER
19. Efficient Information Visualization of Multivariate and Time-Varying Data
Sammanfattning : Data can be found everywhere, for example in the form of price, size, weight and colour of all products sold by a company, or as time series of daily observations of temperature, precipitation, wind and visibility from thousands of stations. Due to their size and complexity it is intrinsically hard to form a global overview and understanding of them. LÄS MER
20. Dissolving pulp : Multivariate Characterisation and Analysis of Reactivity and Spectroscopic Properties
Sammanfattning : Various chemical properties can be used to characterise dissolving pulp. The quality of the pulp must be carefully controlled to ensure that it meets the requirements for its intended use and the further processes to be applied. LÄS MER
