  2. 6. Analysis of Degradation Products from Wood and Methods for Detoxification of Lignocellulose Hydrolysates

    Author : Per Persson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; galactoglucomannan; mass spectrometry; liquid chromatography; sugar degradation; detoxification; fermentation inhibitors; lignocellulose hydrolysates; Ethanol production; softwood; Analytical chemistry; Analytisk kemi; countercurrent supercritical fluid extraction;

    Abstract : In order to produce fuel ethanol from lignocellulose, it is necessary to hydrolyse the sugar-containing constituents hemicellulose and cellulose. During acid hydrolysis, a number of compounds are formed or liberated in addition to the fermentable monomeric sugars. READ MORE

  4. 7. Annealing Based Optimization Methods for Signal Processing Applications

    Author : Per Persson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combinatorial optimization; annealing; digital filter design; adaptive filtering;

    Abstract : In this thesis, a class of combinatorial optimization methods rooted in statistical mechanics and their use in signal processing applications will be discussed. The thesis consists of two separate parts. READ MORE

  5. 8. Parallel Numerical Procedures for the Solution of Contact-Impact Problems

    Author : Per Persson; Karl Schweizerhof; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Finite element (FE) simulations of complex problems tend to yield very large models if detailed knowledge of the problem is required. As the model becomes larger, the time needed for solving the problem increases. The solution time is even longer if contact is present in the model. READ MORE

  6. 9. Strategies for cellulose fiber modification

    Author : Per Persson; KTH; []
    Keywords : Candida antarctica lipase B; cationic catalysis; cellulose-binding module; dendrimer; enzymatic polymerization; fiber modification; silica-cast replica; sol-gel mineralization; organocatalysis; xyloglucan endotransglycosylase;

    Abstract : This thesis describes strategies for and examples ofcellulose fiber modification.The ability of an engineered biocatalyst, acellulose-binding module fused to theCandida antarcticalipase B, to catalyze ring-openingpolymerization of e-caprolactone in close proximity tocellulose fiber surfaces was explored.

  7. 10. Toward a grounded theory for support of command and control in military coalitions

    Author : Per-Arne Persson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Command and control in military operations constitute a complex web of interrelated cognitive activities and information processes. Today, the practice of command and control is affected by simultaneous social and technological changes. READ MORE
