  4. 2. Estimation of wood fibre length distributions from censored mixture data

    Author : Ingrid Svensson; Sara Sjöstedt - de Luna; Lennart Bondesson; Aila Särkkä; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; censoring; fibre length distribution; identifiability; increment core; length bias; mixture; stochastic EM algorithm; Mathematical statistics; Matematisk statistik;

    Abstract : The motivating forestry background for this thesis is the need for fast, non-destructive, and cost-efficient methods to estimate fibre length distributions in standing trees in order to evaluate the effect of silvicultural methods and breeding programs on fibre length. The usage of increment cores is a commonly used non-destructive sampling method in forestry. READ MORE

  5. 3. Pancreas Transplantation: Development of Successful Preclinical Models

    Abstract : Pancreas transplantation is today a technically successful procedure and provides an alternative to insulin injections for the treatment of Type I diabetes mellitus. This thesis was undertaken while pancreas transplantation was developing and while several fundamental questions were being asked about both endocrine and exocrine drainage of the transplanted pancreas as well as how best to diagnose and prevent rejection.

  6. 4. Residual Stress in Additive Manufacturing : Control using orientation and scan strategies

    Author : Prabhat Pant; Ru Peng; Johan Moverare; Kjell Simonsson; Thomas Niendorf; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Residual stress; Neutron diffraction; FEM; Scan strategies; Build orientations;

    Abstract : Components with complex features that are designed with their function as a core aspect often are not viable to be manufactured with traditional methods. This has been a bottleneck in the past, leading to heavier parts with various sub-assemblies and a significant waste of material. READ MORE
