  2. 1. Efficient Solvers for Space-Time Discontinuous Galerkin Spectral Element Methods

    Author : Lea Miko Versbach; Numerisk analys; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Discontinuous Galerkin Method; Spectral Element Method; Finite Volume Method; Implicit Schemes; Preconditioner; Multigrid Method; Space-Time; Lobatto IIIC Method; Local Fourier Analysis;

    Abstract : In this thesis we study efficient solvers for space-time discontinuous Galerkin spectral element methods (DG-SEM). These discretizations result in fully implicit schemes of variable order in both spatial and temporal directions. READ MORE

  5. 3. Development and Applications of Detailed Kinetic Models for the Soot Particle Size Distribution Function

    Author : Karl Netzell; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; flamelet model; Physics; particle distribution; soot; moment method; sectional method; particle size distribution function;

    Abstract : Two different mathematical methods of implementing a detailed kinetic soot model have been employed in this work. The theoretical description of the soot modeling employed in this work is divided into three parts. Initially a detailed kinetic soot model is described from a chemistry and physics perspective.

  6. 4. PID control of TITO systems

    Author : Pontus Nordfeldt; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decoupling; PID Control; Linear Systems; Process Control; Multi-variable Control;

    Abstract : This thesis treats controller design and tuning for systems with two input signals and two output signals in the process industry. Two design methods that can be combined to form a core in an algorithm for automatic design and tuning for the considered systems are presented. READ MORE

  7. 5. Towards empirically grounded guidance for resource efficiency: Applying, developing and synthesising environmental assessments

    Author : Daniel Böckin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Circular Business Models; guidelines; business models; synthesis; Life Cycle Assessment; decoupling; resource efficiency; 3D-printing; Circular Economy; waste hierarchy;

    Abstract : Numerous solutions have been proposed to mitigate environmental damage, including resource efficiency and the vision of circular economy. Suggested solutions are often formulated as guidelines and heuristics like in the EU waste hierarchy, so-called R-hierarchies for resource efficiency and various guidelines for circular business models.
