  3. 2. Accuracy and Convergence Studies of the Numerical Solution of Compressible Flow Problems

    Författare :Erik Sterner; Per Lötstedt; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computational fluid dynamics; Navier-Stokes equations; convergence acceleration; preconditioning; semi-implicit; multiblock; multigrid; finite volume method; Numerical Analysis; Numerisk analys;

    Sammanfattning : The numerical solution of compressible flow problems governed by the Navier-Stokes equations is considered. A finite volume method is used for the discretization in space. Different techniques to accelerate the convergence to a steady state are suggested, and the accuracy of the spatial difference operator is analyzed. LÄS MER

  4. 3. Climate Change: Models, Metrics and Meaning Making

    Författare :Erik Sterner; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate Science Literacy; Emission Metrics; Knowledge-Behavior Gap; Short-lived Climate Forcers; SF Failure; Integral Theory; Carbon Cycle; Sea Level Rise; Common Pool Resources; Resource Extraction;

    Sammanfattning : This thesis, combining research in climate science and educational science, investigates different aspects of climate knowledge. It consists of five papers and covers three major topics: emission metrics, public understanding of atmospheric CO2 accumulation, and spatial modelling of natural resource use. LÄS MER

  5. 4. Comparing Climate Forcers on a Common Scale

    Författare :Erik Sterner; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spatial-temporal Optimization; Carbon Cycle; Greenhouse Gases; Short-lived Climate Forcers; Upwelling-Diffusion; Metric; Energy Balance; Sea Level Rise; Non-cooperative Nash Equilibrium; Resource Extraction;

    Sammanfattning : The climate is changing at a rapid pace. Through the United Nations Framework Convention on Climate Change (UNFCCC), the world has agreed to hold the on-going temperature increase below 2 °C. Climate change is caused by emissions of different atmospheric species (climate forcers). LÄS MER

  7. 5. Engineering enzymes towards biotherapeutic applications using ancestral sequence reconstruction

    Författare :Natalie Hendrikse; Per-Olof Syrén; Johan Rockberg; Erik Nordling; Reinhard Sterner; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; enzyme engineering; enzyme evolution; ancestral sequence reconstruction; therapeutic enzymes; terpene cyclases; ammonia-lyases; sulfatases; lysosomal enzymes; Kemi; Chemistry;

    Sammanfattning : Enzymes are versatile biocatalysts that fulfill essential functions in all forms of life and, therefore, play an important role in health and disease. One specific application of enzymes in life science is their use as biopharmaceuticals, which typically benefits from high catalytic activity and stability. LÄS MER
