  2. 16. Short Term Operation of District Heating Systems: An Application of Mathematical Programming

    Author : Hans Eriksson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This work treats the introduction of rigorous optimisation methods as a decision aid in the short term operation of district heating systems. The conditions for operation of district heating systems are investigated. Arguments for the necessity of a systems model that is capable of handling the discrete nature of the problem are presented.

  4. 17. Electronic Transport in Materials

    Author : Velimir Meded; Susanne Mirbt; Ingrid Mertig; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Electronic Structure; Ab initio; Condensed Matter Theory; Hydrogen; Boltzmann Transport Equation; Magnetism; Alloys; Fysik; Physics; Fysik;

    Abstract : Transport properties within the Boltzmann transport equation for metallic multi-layer structures as well as bulk materials, were the prime topic of this work. Ab initio total energy calculations for Hydrogen loaded metallic multi-layers were performed in order to shed some light onto problem of H depleted layers at the interfaces that have been experimentally observed.

  5. 18. Experimental and Numerical Investigations of Ultra-Cold Atoms

    Author : Magnus Rehn; Anders Kastberg; Claude Dion; Matti Kaivola; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ultracold atoms; optical lattices; Bose-Einstein condensation; quantum phase transitions; Physics; Fysik;

    Abstract : I have been one of the main responsible for building a new laboratory for Bose-Einstein condensation with 87Rb. In particular, the experimental setup has been designed for performing experiments with Bose-Einstein condensates load into optical lattices of variable geometries. All parts essential for Bose-Einstein condensation are in place. READ MORE

  6. 19. Laser-based diagnostics for investigating soot formation in combustion processes

    Author : MANU Mannazhi; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soot formation; Laser diagnostics; Combustion; Laser-induced Incandescence; Fysicumarkivet A2022:Mannazhi;

    Abstract : In this work, laser-based diagnostic techniques were developed and applied to investigate soot formation in small-scale laboratory burners as well as in practical combustion devices. Quantitative 2D laser-induced incandescence (LII) measurements often use a cylindrical lens to shape the beam and illuminate the planar region of interest. READ MORE

  7. 20. Computer Modeling of HCCI Combustion

    Author : Roy Ogink; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; detailed-chemistry; surrogate fuel; homogeneous charge compression ignition; internal combustion engines; modeling; HCCI; gasoline; auto-ignition; combustion;

    Abstract : During the last decade an alternative to conventional internal combustion engines, i.e. spark-ignited and Diesel engines, has been under investigation by an ever-increasing number of research groups. READ MORE
