  2. 16. SiC based field effect sensors and sensor systems for combustion control applications

    Author : Mike Andersson; Anita Lloyd Spetz; Udo Weimar; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SiC; Field Effect Sensors; Combustion Control; Other physics; Övrig fysik;

    Abstract : Increasing oil prices and concerns about global warming have reinforced the interest in biofuels for domestic and district heating, most commonly through combustion of solid biomass like wood logs, hog fuel and pellets. Combustion at non-optimal conditions can, however, lead to substantial emissions of noxious compounds like unburned hydrocarbons, carbon monoxide, and nitrogen oxides as well as the generation of soot.

  4. 17. Bioenergy from Swedish forests : A Study of extraction methods, quality and effects for forest owners

    Author : Daniel Nilsson; Johan Bergh; Peter Lerman; Gudmund Vollbrecht; Nasko Terziew; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; logging residues; forest fuels; moisture content; needles; nutrients; moisture content measurements; Norway spruce; dry-stacking; fresh-stacking; Forestry and Wood Technology; Skog och träteknik;

    Abstract : The forest constitutes a very important element of renewable natural resources and makes a significant contribution to the Swedish bioeconomy. Biofuels are Sweden’s largest source of energy; of all the energy we use, 32% comes from biofuels, and of this approximately 85% comes from the forest and the forestry sector. READ MORE

  5. 18. Calibration of constitutive models with error control

    Author : Håkan Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this thesis a framework for the calibration ofconstitutive models is presented. The framework involves theformulation of an optimization problem which is solved usingstrategies based on, essentially, Newton's method. READ MORE

  6. 19. Soil moisture conditions control nutrient accumulation, carbon storage and tree growth in boreal forest landscapes

    Author : Johannes Larson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Forest and soil properties change across landscapes due to the complex interactions between various environmental factors. In many landscapes, topography exerts a major influence on the variation in soil moisture conditions, which in turn largely affects soil properties and processes. READ MORE

  7. 20. An X-ray LogScanner : a tool for control of the sawmill process

    Author : Stig Grundberg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Abstract : Wood is a biological material with great variability. Every piece of wood is a unique individual. The great challenge in the wood products manufacturing process has always been to select pieces of wood with properties that fulfil the product requirements. READ MORE
