  1. 1. Constraining double neutron star binary evolution from the spatial distribution of short gamma-ray bursts

    University essay from Lunds universitet/Astronomi

    Author : Oscar Andersson; [2019]
    Keywords : Physics and Astronomy;

    Abstract : Short gamma-ray bursts are often observed at large spatial offsets from their host galaxies. Neutron star mergers in double neutron star binaries have also recently been confirmed as a progenitor of short gamma-ray bursts (Abbott et al. 2017). READ MORE

  2. 2. Galaxy evolution in extreme environments

    University essay from Lunds universitet/Astronomi

    Author : Samhitha Vadlamani; [2019]
    Keywords : Galaxy evolution; interactions; starburst; Compact galaxy groups; Stephan s Quintet; Physics and Astronomy;

    Abstract : Interactions play a crucial role in determining how galaxies evolve in terms of their morphologies and star formation histories, since the majority of the known galaxies in the nearby Universe are found to exist in groups. Compact groups of galaxies are of particular interest as they contain a small number of galaxies in dense configurations and host repeated interactions between them, enabling us to capture signatures of these interactions (e.

    University essay from Umeå universitet/Institutionen för psykologi; Umeå universitet/Institutionen för psykologi

    Author : Sofia Larsson; Pauline Mattsson; [2019]
    Keywords : Indoor navigation; spatial ability; vertical motion; visual aid; Inomhusnavigering; spatial förmåga; vertikal rörelse; visuellt hjälpmedel;

    Abstract : Vertikala strukturer i byggnader har blivit väldigt vanligt och mer komplexa, därmed ökar vikten av wayfinding. Syftet med denna studie var att undersöka om en tredimensionell modell av en spiraltrappa ökar spatiala orienteringen när man rör sig vertikalt via den motsvarande existerande trappan. READ MORE

  4. 4. Development of a Concealed Power and Signal Transfer System for Sliding Doors

    University essay from Lunds universitet/Produktutveckling

    Author : Max Koskinen; Jakob Alvelid; [2019]
    Keywords : Product development; Sliding doors; Power transfer; Signal transfer; Spiral cable; Rapid prototyping; Technology and Engineering;

    Abstract : This master’s thesis report describes the product development process of a durable and concealed product for transferring power and signals to the moving door leafs of sliding doors. The thesis has been conducted in collaboration with Assa Abloy Entrance Systems, with the goal of enabling the use of accessories such as privacy e-glass, screens integrated in the glass, electric locks and sensors mounted on the door leafs for their sliding doors.
