  2. 21. Worth weighting for : studies on benchmark dose analysis in relation to animal ethics in toxicity testing

    Author : Joakim Ringblom; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : A purpose of chemical health risk assessment is to characterize the nature and size of the health risk associated with exposure to chemicals, including identification of a dose below which toxic effects are not expected or negligible. This is usually based on analysis of dose-response data from toxicity studies on animals. READ MORE

  4. 22. The Full Multigrid Method Applied to Turbulent Flow in Ventilated Enclosures Using Structured and Unstructured Grids

    Author : Peter Emvin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; adaptivity; finite volume; local mesh refinement; finite element; k-omega large Eddy simulation; ventilated enclosure; k-epsilon; multigrid;

    Abstract : Computational fluid dynamics require large computer resources and it is thus of paramount interest to have as efficient an algorithm as possible. This means that both an accurate discretization and a fast solver are required. In this work, we have used the full multigrid concept, which is a general and optimal solver. READ MORE

  5. 23. Performance Assessment of Wastewater Treatment Plants : Multi-Objective Analysis Using Plant-Wide Models

    Author : MAGNUS ARNELL; Ulf Jeppsson; Bengt Carlsson; Hans Bertil Wittgren; Diego Rosso; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; benchmarking; BSM; samrötning; energieffektivitet; växthusgasutsläpp; livscykelanalys; matematisk modellering; avloppsvattenrening; benchmarking; BSM; codigestion; energy efficiency; greenhouse gases; life cycle assessment; mathematical modelling; wastewater treatment; benchmarking;

    Abstract : As the knowledge about anthropogenic impacts of climate change has grown, the awareness of the contributions from treatment of wastewater has widened the scope for wastewater treatment plants (WWTPs). Not only shall ever stricter effluent constraints be met, but also energy efficiency be increased, greenhouse gases mitigated and resources recovered. READ MORE

  6. 24. Modelling Weather Dynamics for Weather Derivatives Pricing

    Author : Emanuel Evarest Sinkwembe; Martin Singull; Xiangfeng Yang; Fredrik Berntsson; Erik Lindström; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis focuses on developing an appropriate stochastic model for temperature dynamics as a means of pricing weather derivative contracts based on temperature. There are various methods for pricing weather derivatives ranging from simple one like historical burn analysis, which does not involve modeling the underlying weather variable to complex ones that require Monte Carlo simulations to achieve explicit weather derivatives contract prices, particularly the daily average temperature (DAT) dynamics models.

  7. 25. Least Squares Methods for System Identification of Structured Models

    Author : Miguel Galrinho; Håkan Hjalmarsson; Lennart Ljung; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The purpose of system identification is to build mathematical models for dynamical systems from experimental data. With the current increase in complexity of engineering systems, an important challenge is to develop accurate and computationally efficient algorithms. READ MORE
