  2. 1. On Some Properties of Interior Methods for Optimization

    Author : Göran Sporre; KTH; []
    Keywords : Interior method; primal-dual interior method; linear programming; quadratic programming; nonlinear programming; semidefinite programming; weighted least-squares problems; central path;

    Abstract : This thesis consists of four independent papers concerningdifferent aspects of interior methods for optimization. Threeof the papers focus on theoretical aspects while the fourth oneconcerns some computational experiments. READ MORE

  4. 2. Continuity and Change : Essays on path-dependence in economic geography and good food

    Author : Pepijn Olders; Dominic Power; Henrik Mattsson; Anders Malmberg; Andrés Rodríguez-Pose; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; path dependence; continuity; change; expert opinion; economic geography; restaurants; low-emission vehicles; PDO PGI labels;

    Abstract : How can it be, that in our rapidly changing world certain things remain recognisably the same for such a long time? This dissertation is concerned with the economic geography of path-dependence and seeks to explain selected everyday examples of continuity and change. How can French restaurants and chefs be successful for decades despite changes in taste? Why are cars powered by fossil fuels still around while there are many novel and cleaner alternatives? What explains the re-invention of local food products in spite of the influx of many new products from around the world? These are the question this dissertation tries to explain as spatial expressions of ‘path-dependence’. READ MORE

  5. 3. Neural correlates of diverse navigational strategies

    Author : Marcel Sayre; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; central complex; connectome; path integration; bees; ants; neuroethology; neuroscience;

    Abstract : Insects have evolved diverse and remarkable strategies for navigating in various ecologies all over the world. In particular, central place foragers, such as bees and ants, have become renowned for their fascinating navigational capabilities. At the heart of insect navigation lies a brain area known as the central complex (CX). READ MORE

  6. 4. Topology off the beaten path : From critical to non-Hermitian systems

    Author : Carlos Ortega-Taberner; Maria Hermanns; Joost Slingerland; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Topological phases; Critical systems; Non-Hermitian systems; Theoretical Physics; teoretisk fysik;

    Abstract : A central topic in condensed matter research during the last decades has been the study and classification of topological phases of matter. Topological insulators in particular, a subset of symmetry protected topological phases, have been investigated for over a decade. READ MORE

  7. 5. Technology Dynamics in Multi-Technology Industries : Selection and Variety Creation through the Lens of Path Dependency and Path Generation

    Author : Ksenia Onufrey; Anna Bergek; Hans Andersson; Magnus Holmén; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : This thesis studies technological development in multi-technology industries, or industries characterized by co-existence of several technological alternatives that are used in the same or largely overlapping applications and markets. Although a lot of industries can be considered as multi-technological, they are understudied in the current research. READ MORE
