  1. 1. PDEModelica – A High-Level Language for Modeling with Partial Differential Equations

    University dissertation from Institutionen för datavetenskap

    Author : Levon Saldamli; Peter Fritzson; Bernhard Bachmann; Francesco di Casella; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mathematical modeling; PDEModelica; Modelica; object-oriented modeling; equation-based modeling; declarative modeling; high-level modeling languages; mathematical modeling languages; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Abstract : This thesis describes work on a new high-level mathematical modeling language and framework called PDEModelica for modeling with partial differential equations. It is an extension to the current Modelica modeling language for object-oriented, equation-based modeling based on differential and algebraic equations. READ MORE

  2. 2. Automation of Computational Mathematical Modeling

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Anders Logg; Göteborgs universitet.; Gothenburg University.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computational mathematical modeling; automation; adaptivity; multi-adaptivity; individual time steps; dual problem; a priori; a posteriori; model reduction; individual time steps; a posteriori; automation; model reduction; dual problem; adaptivity; a priori; multi-adaptivity;

    Abstract : This thesis concerns the Automation of Computational Mathematical Modeling (CMM), involving the key steps of automation of (i) discretization, (ii) discrete solution, (iii) error control, (iv) modeling, and (v) optimization. The automation of (i)--(ii) is realized through multi-adaptive Galerkin methods on general discretizations of space-time with time steps variable in space. READ MORE

  3. 3. Distributed Photovoltaics, Household Electricity Use and Electric Vehicle Charging Mathematical Modeling and Case Studies

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Joakim Munkhammar; Joakim Widén; Ewa Wäckelgård; Jesper Rydén; Peter Lund; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed Photovoltaics; Household Electricity Use; Electric Vehicle Charging; Markov Chain Modeling; Probability Distribution Modeling; Data Analysis; Self-Consumption; Grid Interaction.; Engineering Science; Teknisk fysik;

    Abstract : Technological improvements along with falling prices on photovoltaic (PV) panels and electric vehicles (EVs) suggest that they might become more common in the future. The introduction of distributed PV power production and EV charging has a considerable impact on the power system, in particular at the end-user in the electricity grid. READ MORE

  4. 4. A pseudoparabolic reaction-diffusion-mechanics system Modeling, analysis and simulation

    University dissertation from Karlstad : Karlstads universitet

    Author : Arthur Vromans; Adrian Muntean; Martin Lind; Mohammad Asadzadeh; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; reaction-diffusion-mechanics model; parameter delimitation; parabolic-pseudoparabolic equations; weak solvability; Rothe method; periodic homogenization; Matematik; Mathematics;

    Abstract : In this thesis, parabolic-pseudoparabolic equations are derived coupling chemical reactions, diffusion, flow and mechanics in a heterogeneous medium using the framework of mixture theory. The weak solvability in 1-D of the obtained models is studied. READ MORE

  5. 5. Mathematical Modeling of Biofilms: Theory, Numerics and Applications

    University dissertation from Centre for Mathematical Sciences, Lund University

    Author : Erik Alpkvist; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mathematical modeling; Mathematics; conservation laws; biofilm; Matematik;

    Abstract : A biofilm is a complex and diverse aggregation of microorganisms at surface comprised of among different things a protective adhesive matrix of extracellular polymeric substance. Biofilm research represents a broad range of sciences joining efforts within an interdisciplinary field of research. READ MORE
