  1. 1. Optimal thinning : a theoretical investigation on individual-tree level

    Författare :Peter Fransson; Åke Brännström; Ola Lindroos; Oskar Franklin; Per Lundberg; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; Forest management; Simulation; Optimization; Spatially explicit model; Individual-based model;

    Sammanfattning : Paper I: In paper I, we asked how a tree should optimally allocate its resources to maximize its fitness. We let a subject tree grow in an environment shaded by nearby competing trees. The competitors were assumed to have reached maturity and had stopped growing, thus creating a static light environment for the subject tree to grow in. LÄS MER

  2. 2. Hydrokinetic Resource Assessment : Measurements and Models

    Författare :Emilia Lalander; Mats Leijon; Mitsuhiro Kawase; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The conversion of kinetic energy in water currents into electricity has gained great attention the past years. The conversion systems are stand-alone units that typically consist of a turbine, driven by the water stream, with a generator connected to it. LÄS MER

  3. 3. Optimal Control of Partial Differential Equations in Optimal Design

    Författare :Jesper Carlsson; Anders Szepessy; Peter Hansbo; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Optimal design; Numerical analysis; Numerisk analys;

    Sammanfattning : This thesis concerns the approximation of optimally controlled partial differential equations for inverse problems in optimal design. Important examples of such problems are optimal material design and parameter reconstruction. In optimal material design the goal is to construct a material that meets some optimality criterion, e.g. LÄS MER

  4. 4. Optimal Control of Electrified Powertrains

    Författare :Martin Sivertsson; Lars Eriksson; Giorgio Rizzoni; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal Control; Diesel-Electric; Hybrid Electric Vehicles;

    Sammanfattning : Vehicle powertrain electrification, i.e. combining the internal combustion engine (ICE) with an electric motor (EM), is a potential way of meeting the increased demands for efficient and low emission transportation, at a price of increased powertrain complexity since more degrees of freedom (DoF) have been introduced.

  5. 5. Electromagnetic Modeling and Sensitivity-Based Optimization of Medical Devices

    Författare :Oskar Talcoth; Chalmers University of Technology; []
    Nyckelord :helical conductors; optimal measurements; thin-wire approximation; inverse problems; Convex optimization; pacemakers; design of experiments; MR safety; multi-scale; magnetic resonance imaging; magnetic tracking; optimal sensor placement;

    Sammanfattning : Electromagnetics is a fundamental part of biomedical engineering and modern healthcare due to the electromagnetic nature of several important processes in the human body and the interactions of electromagnetic fields with the human body. As a consequence, electromagnetics is exploited for diagnostic and therapeutic purposes by a multitude of medical devices. LÄS MER
