  2. 21. On the Solubility of Wood Hemicelluloses in Water and its Influence on the Adsorption at Cellulose/Water Interfaces

    Author : Saina Kishani; Lars Wågberg; Bernard Cathala; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood; Hemicellulose; Solubility; Adsorption; Interaction; Cellulose; Size distribution;

    Abstract : Hemicelluloses are a group of natural polysaccharides and one of the main components of wood. The availability and biodegradability of these polymers have created a great interest in developing new bio-based materials or composites from these materials for different end-use purposes.

  4. 22. Regulation of aortic wall mechanics and stress : An experimental study in man

    Author : Håkan Åstrand; Toste Länne; Matts Karlsson; Martin Björck; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aorta; wall stress; remodeling; IMT; gender; diabetes mellitus; aging; collagen; elastin; Vascular surgery; Kärlkirurgi;

    Abstract : The abdominal aorta (AA) in man is a vulnerable artery prone to atherosclerosis as well as aneurysmatic dilation. The underlying aortic composition, mechanical properties as well as the mechanisms responsible for age-related changes and vascular disease are however largely unknown. READ MORE

  5. 23. High-order accurate calculations and bounds on effective properties of composites

    Author : Henrik Christiansson; KTH; []
    Keywords : ;

    Abstract : A classical problem in material science has been the studyof electrostatic and elastostatic properties of compositematerials. The complexity of the microstructure of randomcomposite media makes an exact calculation of the effectiveproperties very difficult. READ MORE

  6. 24. Theoretical Investigation of the Effect of Interface Dielectric Properties on Electric Double Layer Interactions

    Author : Erik Wernersson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Results for a simple model of interacting electric double layers are presented for the geometry of two parallel planar walls. The wall and solution media are described as dielectric continua, characterized by their frequency dependent dielectric functions. READ MORE

  7. 25. Variational Tensor-Based Models for Image Diffusion in Non-Linear Domains

    Author : Freddie Åström; Michael Felsberg; George Baravdish; Reiner Lenz; Christoph Schnörr; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; image diffusion; variational formulation; denoising; tensor; non-linear;

    Abstract : This dissertation addresses the problem of adaptive image filtering.Although the topic has a long history in the image processing community, researchers continuously present novel methods to obtain ever better image restoration results. READ MORE
