  2. 1. Tools for Designing Mobile Interaction with the Physical Environment in Outdoor Lessons

    Author : Johan Eliasson; Teresa Cerratto Pargman; Robert Ramberg; Ola Knutsson; Lyn Pemberton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human-Computer Interaction; Design Tools; Concept-Driven Design; Mobile Learning; Design-Based Research DBR ; Outdoor Lessons; Field Trips; Design Theory; Design Process; Distraction; Man-Machine-Interaction MMI ; människa-maskin-interaktion MMI ;

    Abstract : Mobile technologies are increasingly being used to support students in outdoor learning activities. For instance, in a growing number of research projects, smartphones and positioning technologies are being used to support students in exploring the natural environment. READ MORE

  4. 2. Localic Categories of Models and Categorical Aspects of Intuitionistic Ramified Type Theory

    Author : Johan Lindberg; Erik Palmgren; Peter LeFanu Lumsdaine; Henrik Forssell; Benno van den Berg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Topos theory; predicative topos theory; ramified type theory; type theory; localic groupoids; Mathematics; matematik;

    Abstract : This thesis contains three papers, all in the general area of categorical logic, together with an introductory part with some minor results and proofs of known results which does not appear to be (easily) available in the literature.In Papers I and II we investigate the formal system Intuitionistic Ramified Type Theory (IRTT), introduced by Erik Palmgren, as an approach to predicative topos theory.

  5. 3. The architecture of the aging brain : functional reorganization, structural changes, and the role of dopamine receptors

    Author : Robin Pedersen; Alireza Salami; Anna Rieckmann; Anders Wåhlin; Lars Nyberg; Roser Sala-Llonch; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain architecture; functional connectivity; dopamine; aging; cognition; memory; functional magnetic resonance imaging; positron emission tomography; graph theory; Laplacian eigenmapping; gradient;

    Abstract : Aging is associated with reorganization of functional brain architecture, potentially leading tocognitive decline in older age. However, the mechanisms responsible for alterations in functionalbrain architecture remain poorly understood. READ MORE

  6. 4. Computational Insights into Atomic Scale Wear Processes in Cemented Carbides

    Author : Emil Edin; Rajeev Ahuja; Andreas Blomqvist; Jonas Östby; Wei Luo; Hannes Jónsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; WC; Cemented Carbides; Diffusion; Wear; Interfaces; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : As Ti-alloys become more and more utilized the need for efficient and robust manufacturing of Ti-alloy components increase in importance. Ti-alloys are more difficult to machine than e.g. steel, mainly due to their poor thermal conductivity leading to rapid tool wear. READ MORE

  7. 5. On the possibility of limited weighing of lives

    Author : Daniel Ramöller; Gustaf Arrhenius; Krister Bykvist; Hilary Greaves; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Aggregation; Axiology; Deontic Morality; Distribution; Ethics; Impartiality; Morality; Social Choice; Trade-offs; Values; Welfare; praktisk filosofi; Practical Philosophy;

    Abstract : This thesis discusses the possibility of limited moral trade-offs between different people’s welfare. In chapter 2, I introduce the two central limited trade-off conditions. First, according to minimal infinite superiority, significantly benefiting one person matters more than slightly benefiting each of any number of better-off people. READ MORE
