1. 6. Applied problems and computational methods in radiative transfer

   Författare :Magnus Neuman; Per Edström; Daniel Åberg; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Light scattering in turbid media is essential for such diverse applications as paperand print, computer rendering, optical tomography, astrophysics and remote sensing.This thesis investigates angular variations of light reflected from plane-parallelturbid media using both mathematical models and reflectance measurements, dealswith several applications and proposes novel computational methods for solving thegoverning equations.

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chemometrics; pulse-coupled neural networks; peak alignment; class separability; molecular dynamics; Monte Carlo; expanded ensembles; free energy; Analytical chemistry; Analytisk kemi;

   Sammanfattning : This thesis is based on five papers addressing variance reduction in different ways. The papers have in common that they all present new numerical methods. LÄS MER

4. 8. Translating Popular Education : Civil Society Cooperation between Sweden and Estonia

   Författare :Pelle Åberg; Anders Uhlin; Ulrika Mörth; Karl Magnus Johansson; Mikko Lagerspetz; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Translation; diffusion; socialization; popular education; civil society; Sweden; Estonia; transnational cooperation; democracy promotion; ABF; AHL; Political science; Statsvetenskap; Political Science; statsvetenskap;

   Sammanfattning : By their very nature, attempts by civil society organizations to promote democracy abroad involve cooperation and contact across the borders of nation states. The dissemination of the ideas and practices of the promoters is often essential; in the case of Swedish democracy promotion, popular education or folkbildning has been important. LÄS MER

5. 9. Solving the correspondence problem in analytical chemistry : Automated methods for alignment and quantification of multiple signals

   Författare :Erik Alm; Magnus Åberg; Beata Walczak; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

   Sammanfattning : When applying statistical data analysis techniques to analytical chemical data, all variables must have correspondence over the samples dimension in order for the analysis to generate meaningful results. Peak shifts in NMR and chromatography destroys that correspondence and creates data matrices that have to be aligned before analysis. LÄS MER

7. 10. Chemometrics : Unravelling information from complex data generated by modern instruments

   Författare :Pedro F. M. de Sousa; Magnus Åberg; Johan Trygg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemometrics; Chromatography; Mass spectrometry; DIA; PCA; PLS; Experimental Design; DNA; adductomics; Analytical Chemistry; analytisk kemi;

   Sammanfattning : Chemometrics is a discipline dedicated to solving problems arising from complicated analytical systems, combining statistics, mathematics, and computational programming languages.This thesis is based on the work developed in four scientific projects published as papers in scientific journals.
