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

    Author : Levon Saldamli; Peter Fritzson; Bernhard Bachmann; Francesco di Casella; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; mathematical modeling; PDEModelica; Modelica; object-oriented modeling; equation-based modeling; declarative modeling; high-level modeling languages; mathematical modeling languages; Computer science; 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. On the use of traffic flows for improved transportation systems : Mathematical modeling and applications

    Author : Henrik Fredriksson; Mattias Dahl; Johan Holmgren; Benny Lövström; Joakim Ekström; Blekinge Tekniska Högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mathematical modeling; Transportation systems; Link flows; Mathematics and applications; Matematik med tillämpningar;

    Abstract : This thesis concerns the mathematical modeling of transportation systems for improved decision support and analysis of transportation-related problems. The main purpose of this thesis is to develop and evaluate models and methods that exploit link flows. READ MORE

  3. 3. Automation of Computational Mathematical Modeling

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

    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

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

    Author : Joakim Munkhammar; Joakim Widén; Ewa Wäckelgård; Jesper Rydén; Peter Lund; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  5. 5. From Penicillin Binding Proteins to Community Interventions : Mathematical and Statistical Models Related to Antibiotic Resistance

    Author : Patricia Geli Rolfhamre; Åke Svensson; Mikael Andersson; Dan I. Andersson; Karl Ekdahl; Bruce R. Levin; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; antibiotic resistance; mathematical modeling; pharmacokinetics; pharmacodynamics; penicillin binding protein; postantibiotic effect; reversibility; selection; community intervention; Mathematical statistics; Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Abstract : Antibiotic resistance has become a major public health concern and mathematical models are important analytical tools for the understanding, evaluation and prediction of the resistance problem and related control strategies.The risk of emerging antibiotic resistance and selection has rarely been a concern in the design of antibiotic drug dosing regimens.
