  1. 6. Operando X-Ray Imaging of Battery Electrodes

    Författare :Antoine Klein; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; lithium-ion batteries; XTM; sodium-ion batteries; lithium-sulfur batteries; SAXS.; X-ray imaging;

    Sammanfattning : Batteries are now part of our daily life as they enable easy usage of portable devices and are now essential for us to travel, communicate, work, read, or listen to music. The diversity of battery applications continuously increases and new demands of for instance capacity, charge time and sustainability have emerged. LÄS MER

  3. 7. In the wake of a bird - Quantifying aerodynamic performance of avian flight

    Författare :Marco Klein Heerenbrink; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; animal flight; flight performance; gliding; powered flight; wing morphology; aerodynamics; biomechanics; birds; jackdaw; Corvus monedula; wind tunnel; PIV;

    Sammanfattning : Flight is an expensive form of locomotion, but also offers the ability to travel great distances at relatively low cost. Birds have developed various adaptations for optimizing flight performance. The main aim of this thesis is to identify how morphological variables in birds affect aerodynamic drag and flight performance. LÄS MER

  4. 8. A specific heat ratio model and compression ratio estimation

    Författare :Marcus Klein; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Cylinder pressure modeling and heat release analysis are today important and standard tools for engineers and researchers, when developing and tuning new engines. An accurate specific heat ratio model is important for an accurate heat release analysis, since the specific heat ratio couples the systems energy to other thermodynamic quantities. LÄS MER

  5. 9. Single-Zone Cylinder Pressure Modeling and Estimation for Heat Release Analysis of SI Engines

    Författare :Markus Klein; Lars Eriksson; Lars Nielsen; Per Tunstål; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heat release; parameter estimation; prior knowledge; regularization; specific heat ratio; compression ratio; Systems engineering; Systemteknik;

    Sammanfattning : Cylinder pressure modeling and heat release analysis are today important and standard tools for engineers and researchers, when developing and tuning new engines. Being able to accurately model and extract information from the cylinder pressure is important for the interpretation and validity of the result. LÄS MER
