  2. 1. Nonionic surfactants : A multivariate study

    Author : Lise-Lott Uppgård; Michael Sjöström; Svante Wold; Jiri Damborsky; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AEO; APG; aquatic toxicity; cellulose reactivity; Fock; MLR; multivariate data analysis; nonionic surfactant; PCA; physicochemical properties; PLS; QSAR; surface activity; viscose; Chemistry; Kemi;

    Abstract : In this thesis technical nonionic surfactants are studied using multivariate techniques. The surfactants studied were alkyl ethoxylates (AEOs) and alkyl polyglucosides (APGs). The aquatic toxicity of the surfactants towards two organisms, a shrimp and a rotifer, was examined. The specified effect was lethality, LC50, as indicated by immobilisation. READ MORE

  4. 2. Spectroscopic data and multivariate analysis : tools to study genetic perturbations in poplar trees

    Author : Susanne Wiklund; Ulf Edlund; Olav Kvalheim; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; Metabolomics; Degree of methylation; S-plot; SUS-plot; Metabonomics; Poplar; MLR; PLS; OPLS; PCA; Pectin; Wood; Organic chemistry; Organisk kemi;

    Abstract : In our society in the 21st century one of the greatest challenges is to provide raw materials to the industry in a sustainable way. This requires increased use of renewable raw materials such as wood. Wood is widely used in pulp, paper and textile industries and ongoing research efforts aim to extend the use of wood in e.g. READ MORE

  5. 3. Learning Multidimensional Signal Processing

    Author : Magnus Borga; Hans Knutsson; Josef Kittler; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The subject of this dissertation is to show how learning can be used for multidimensional signal processing, in particular computer vision. Learning is a wide concept, but it can generally be defined as a system’s change of behaviour in order to improve its performance in some sense. READ MORE

  6. 4. Production and characterisation of pine wood powders from a multi-blade shaft mill

    Author : Atanu Kumar Das; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Wood is an important raw material for the manufacture of consumer products and in achieving societal goals for greater sustainability. Wood powders are feedstock for many biorefining and conversion techniques, including chemical, enzymatic and thermochemical processes and for composite manufacture, 3D printing and wood pellet production.

  7. 5. Fire behaviour of selected polymeric materials : Numerical modelling and validation using microscale and bench scale test methods

    Author : Abhishek Bhargava; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DAEM; pyrolysis modelling; Polymer flammability; mass loss rate; Heat release rate HRR ;

    Abstract : The ability to predict fire behaviour of materials is of key interest to building materials industry. Themain reason for it is expensive fire testing and certification costs borne by the manufacturers to bring a finished product to market. READ MORE
