  1. 1. On the determination of diffusion coefficients in bone

    Författare :Abdallah Shokry; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kalman filter; Mathematical model; Spatially dependent diffusion; Diffusion in bone; Diffusion coefficient; Conductivity; Elastic modulus; Porous materials;

    Sammanfattning : Diffusion in bone is needed for bone remodeling and bone healing. Understanding the phenomenon is often important for comprehension bone diseases. Mathematical modeling of the diffusion processes is a required prerequisite in the study of this important physical process in living bone tissue. LÄS MER

  4. 3. Comparing Climate Forcers on a Common Scale

    Författare :Erik Sterner; Chalmers University of Technology; []
    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

  5. 4. Multiscale Stochastic Simulation of Reaction-Transport Processes : Applications in Molecular Systems Biology

    Författare :Andreas Hellander; Per Lötstedt; Sverker Holmgren; Samuel Isaacson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; stochastic simulation; chemical master equation; reaction-diffusion master equation; unstructured mesh; active transport; hybrid methods; URDME; Scientific Computing; Beräkningsvetenskap;

    Sammanfattning : Quantitative descriptions of reaction kinetics formulated at the stochastic mesoscopic level are frequently used to study various aspects of regulation and control in models of cellular control systems. For this type of systems, numerical simulation offers a variety of challenges caused by the high dimensionality of the problem and the multiscale properties often displayed by the biochemical model.
