  2. 21. Improving Modeling with UML by Stereotype-based Language Customization

    Author : Miroslaw Staron; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; UML; Software Engineering; Modeling; Software Development; MDA; Model Driven Development; Unified Modeling Language;

    Abstract : Graphical modeling is becoming an increasingly important part of software engineering as it provides means of increasing productivity by raising the level of abstraction in software devel-opment. One of the most widely adopted modeling notations is the Unified Modeling Language (UML) which has gained popularity due to its generality and broad applicability. READ MORE

  4. 22. Applied Modeling of Moisture Phenomena in Concrete

    Author : Marcin Stelmarczyk; Andrzej Cwirzen; Hans Hedlund; Klaas van Breugel; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; Modeling degree of hydration; Modeling chemically bounded water; Modeling moisture sorption; Modeling moisture transport; Hysteresis; Byggmaterial; Building Materials;

    Abstract : This thesis contains new and improved calculation models, based on applied research merging numerical modeling and material research, in the areas of hydration and chemical binding of water, sorption of moisture and transport of moisture in concrete. The proposed model for hydration and chemical binding of water is based on general kinetics modeling and calculates degree of hydration directly, without using of equivalent time of maturity.

  5. 23. Modeling and Control of Bilinear Systems : Application to the Activated Sludge Process

    Author : Mats Ekman; Bengt Carlsson; Claes Breitholtz; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bilinear systems; modeling; optimal control; parameter estimation; errors-in-variables; activated sludge process; Automatic control; Reglerteknik;

    Abstract : This thesis concerns modeling and control of bilinear systems (BLS). BLS are linear but not jointly linear in state and control. In the first part of the thesis, a background to BLS and their applications to modeling and control is given. READ MORE

  6. 24. Modeling of Hindered Diffusion in Gels

    Author : Jan Gutenwik; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; effective diffusion coefficient; pore size distribution; obstruction; immobilization; modeling; adsorption kinetics; hindered diffusion; simulation program; proteins; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : Hindered diffusion occurs in the most different processes, as has been described in this thesis. It is very important to have an understanding of the influence of hindered diffusion on the mass transfer rate, especially when competing rate processes are acting simultaneously. READ MORE

  7. 25. Modeling and Calibration of Preparative Chromatography

    Author : Niklas Borg; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chromatography; Modeling; Simulation; Calibration; Model based analysis;

    Abstract : In my thesis, I have modeled adsorption chromatography and simulated, calibrated, and analyzed models of adsorption chromatography. While my main focus has been modeling and calibration of the models by estimating the parameters, the models used have been partly new. READ MORE
