  2. 1. Enumeration on words, complexes and polytopes

    Author : Ragnar Freij; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Simplicial complex; discrete Morse theory; Hansen polytope; $3^d$-conjecture; split graph; derangement; pattern containment; pattern packing; composition.; composition.;

    Abstract : This thesis presents four papers, studying enumerative problems on combinatorial structures. The first paper studies Forman's discrete Morse theory in the case where a group acts on the underlying complex. READ MORE

  4. 2. Topics in algorithmic, enumerative and geometric combinatorics

    Author : Ragnar Freij; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Discrete Morse theory; simplicial G-complex; centrally symmetric polytope; split graph; derangement; pattern packing; composition; finite poset; optimal stopping; secretary problem.; finite poset;

    Abstract : This thesis presents five papers, studying enumerative and extremal problems on combinatorial structures. The first paper studies Forman's discrete Morse theory in the case where a group acts on the underlying complex. READ MORE

  5. 3. Innate Confinement Effects in PCL Oligomers as a  Route to Confined Space Crystallisation

    Author : Nima Sanandaji; Ulf W. Gedde; Mikael Hedenqvist; Lars Kloo; Ulrica Edlund; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Crystallisation; Polycaprolactone; PCL; Confined state crystallisation; Metastable Phases; Chemistry; Kemi;

    Abstract : In this work, an in-depth analysis of crystalline characteristics has been performed for a unique set of strictly monodisperse poly-ε-caprolactone (PCL) oligomers. The molecules have different sets of end groups with various degrees of bulkiness and hydrogen bonding potential, affecting their aptitude to pack in ordered crystal structures. READ MORE

  6. 4. Adsorption and Ordering of Surface Active Molecules and Particles at Solid Interfaces and in the Bulk

    Author : Maja S. Hellsing; Adrian R. Rennie; Jöns Hilborn; Julia Higgins; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Factors that influence the process of adsorption and order of dilute and concentrated systems of molecules and particles are explored in this thesis.  The results are based largely on neutron scattering techniques. READ MORE

  7. 5. Modeling Flow and Solute Transport in Packed Beds : Applications in On-site Wastewater Treatment Systems

    Author : Amir Jourak; Krishna M. Pillai; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : The use of separate phosphorus (P) filter units containing replaceable filter materials with a high P binding capacity have been suggested as an appropriate passive method to treat the P from pre-treated domestic wastewater in on-site facilities. A large number of materials have been identified and suggested as being potentially suitable for such filters. READ MORE
