  1. 6. Automated Computational Modeling

    Författare :Johan Jansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; multi-adaptivity; Galerkin; ODE; PDE; plasticity; elasticity; FEM; automated;

    Sammanfattning : This thesis is part of the FEniCS project of Automation of Computational Mathematical Modeling (ACMM) as the modern manifestation of the basic principle of science:formulating mathematical equations (modeling) and solving equations (computation). The vision of FEniCS is to set a new standard towards the goals of generality, efficiency, and simplicity, concerning mathematical methodology, implementation, and application. LÄS MER

  3. 7. Modeling financial volatility : A functional approach with applications to Swedish limit order book data

    Författare :Suad Elezovic; Xavier de Luna; Gunnar Rosenqvist; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Financial data; functional time series; multivariate generalized least squares; seemingly unrelated autoregression; Statistics; computer and systems science; Statistik; data- och systemvetenskap; ekonometri; Econometrics;

    Sammanfattning : This thesis is designed to offer an approach to modeling volatility in the Swedish limit order market. Realized quadratic variation is used as an estimator of the integrated variance, which is a measure of the variability of a stochastic process in continuous time. LÄS MER

  4. 8. Modeling, Control and Optimization of a Plate Reactor

    Författare :Staffan Haugwitz; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mid-ranging control; transition control; start-up; exothermic reaction; chemical reactor; modeling; process control; optimization; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : A new chemical reactor, the Alfa Laval Plate Reactor, is being developed by Alfa Laval, a Swedish world-leading heat exchanger company. The plate reactor combines the high-heat-transfer capabilities of plate heat exchangers with the efficient mixing and reaction control typical of microreactors. LÄS MER

  5. 9. Modeling and Control for Improved Predictability of Cloud Applications

    Författare :Tommi Berner; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; Applied control; Cloud computing; Queuing theory;

    Sammanfattning : Cloud computing has emerged as a key technology in the latest decade and continues to be applied to manage the computing needs of new domains. As a result, the requirements on predictable behavior in the cloud increase, thus the hosted applications need to be recognized as both fault-tolerant and responsive even under difficult conditions.

  7. 10. Meta-Languages and Semantics for Equation-Based Modeling and Simulation

    Författare :David Broman; Peter Fritzson; Jeremy Siek; Thomas Schön; Björn Lisper; Walid Taha; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Meta-language; semantics; EOO; Modelica; equations; modeling; simulation; MKL; Computer science; Datalogi;

    Sammanfattning : Performing computational experiments on mathematical models instead of building and testing physical prototypes can drastically reduce the develop cost for complex systems such as automobiles, aircraft, and powerplants. In the past three decades, a new category of equation-based modeling languages has appeared that is based on acausal and object-oriented modeling principles, enabling good reuse of models. LÄS MER
