  1. 1. Exploring the Treatment of Energy Demand in Energy Systems Engineering Modeling

    Författare :Ingrid Nyström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pulp and paper; Swedish energy system; forest industry scenarios; MARKAL-MACRO; forest industry; soft-linking; industrial energy demand; energy systems engineering modeling; demand decoupling; energy-economy;

    Sammanfattning : The treatment of energy demand in analyses based on energy systems engineering models is explored in this thesis. Two aspects of modeling developments in systems engineering analyses are treated: linking energy systems engineering and economic models and concepts, and incorporating more detailed subsector analyses in energy systems engineering studies.

  3. 2. Development of economic forest tree breeding objectives

    Författare :Mats Berlin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The overall objective of this thesis was to suggest a framework for developing forest tree breeding objectives with particular emphasis on boreal conditions and, as components of this framework, to define breeding objectives and calculate economic weights based on two case studies of Scots pine in northern Sweden. The framework was designed to take into account boreal conditions, with long rotations, heterogeneous raw materials and a diverse production system. LÄS MER

  4. 3. Biomass Potential for Heat, Electricity and Vehicle Fuel in Sweden

    Författare :Peter Hagström; Bengt Hillring; Per Olov Nilsson; Leif Gustafsson; Paul Mitchell; Skogsmästarskolan Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; bioenergy potential; biomass potential; cost analysis; emergy; energy analysis; energy scenarios; systems analysis; thermochemical conversion; SRA - Energy; SRA - Energi;

    Sammanfattning : The main objective of this thesis was to determine how far a biomass quantity, equal to the potential produced within the Swedish borders, could cover the present energy needs inSwedenwith respect to economic and ecological circumstances. Three scenarios were studied where the available biomass was converted to heat, electricity and vehicle fuel. LÄS MER

  5. 4. Terrain machine learning

    Författare :Viktor Wiberg; Martin Servin; Tomas Nordfjell; Eddie Wadbro; Todor Stoyanov; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multibody dynamics simulation; rough terrain vehicle; autonomous vehicles; robotics control; discrete element method; sim-to-real; reinforcement learning; fysik; Physics;

    Sammanfattning : The use of heavy vehicles in rough terrain is vital in the industry but has negative implications for the climate and ecosystem. In addition, the demand for improved efficiency underscores the need to enhance these vehicles' navigation capabilities. LÄS MER

  7. 5. Optimization approaches to tactical planning problems in the forest industry

    Författare :Helene Gunnarsson; Ola Eriksson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : By using decision support tools based on operations research (OR) and optimization in the supply chain in the forest industry, the planning process can be improved and higher profitability can be obtained. The focus of this thesis is on modelling two real-life problems. LÄS MER
