  1. 1. A tale of trees and leaves : subtrees and local convergence

    Författare :Wang Ruoyu; Stephan Wagner; Haslegrave John; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tree; subtree; mean subtree order; Benjamini Schramm convergence; local convergence; Mathematics; Matematik;

    Sammanfattning : Given a tree T, a subtree in T is a subgraph that is a tree itself. The set of subtrees in a tree is related to many important graph parameters, one of which is the mean subtree order. LÄS MER

  2. 2. Photometry of Resolved Stellar Populations in Local Group Galaxies

    Författare :Daniel Faria; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomi; Astronomy; Local Group; Galaxy: halo; Galaxies: dwarf; Galaxy: stellar content; Galaxies: photometry; Techniques: photometric; Stars: fundamental parameters;

    Sammanfattning : This thesis presents results from two projects using photometric observations to investigate stellar populations in Local Group galaxies. In the first project, Strömgren photometry is used to study stellar populations in dwarf spheroidal galaxies. LÄS MER

  3. 3. Methods for material parameter estimation : global and local approach

    Författare :Göran Lindkvist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The rapid development of computing technology has made powerful tools, such as finite element codes, available for more and more companies. The use of simulation tools, predictive engineering, is a prerequisite today in product development. LÄS MER

  4. 4. Local structure and composition : in additively manufactured bulk metallic glasses and composites

    Författare :Inga Katharina Goetz; Jochen M. Schneider; Björgvin Hjörvarsson; Ulf Jansson; Maria Teresa Pérez Prado; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; additive manufacturing; bulk metallic glasses; nanoscale clustering; convective flow; laser nitriding; laser powder bed fusion; metallic glass - ceramic composites; oxygen impurities; mechanical properties; magnetic properties; viscosity; Fysik; Physics;

    Sammanfattning : Additive manufacturing enables the production of complex multi-material geometries and bulk metallic glass parts beyond their critical casting thickness. The local modification of structure, composition, and properties is explored in this thesis with the aim to design novel composite materials and functional gradients. LÄS MER

  5. 5. Lokal Agenda 21 för hållbar utveckling : en studie av miljöfrågan i tillväxtsamhället

    Författare :Björn Forsberg; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sustainable development; economic growth; Local Agenda 21; economism; ecological modernisation; social ecology; dialectic; ecological compromises;

    Sammanfattning : The aim of this thesis is to analyse sustainable development as a political challenge at the local level of governance. It explores how local organisation for sustainable development (LA21, a short form of local Agenda 21) is influenced by economic conditions in contemporary society, as well as the specific conditions in the local context.
