  1. 1. Color and wing size: identifying targets of sexual selection in Drosophila melanogaster

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Ellen Pääjärvi Våg; [2024]
    Nyckelord :Sexual selection; wing interference patterns; Drosophila melanogaster; visual signaling; sexuell selektion; vingmönster; bananfluga; visuell signalering;

    Sammanfattning : This study explores the relationship between wing size, coloration, and reproductivesuccess in Drosophila melanogaster, fruit flies. Sexual selection, a key aspect ofevolutionary biology, often involves visual signaling as a means of displaying geneticinformation. LÄS MER

  3. 2. Improving the public’s ability to find publicly placed bleeding control kits : The effect of signage and bleeding control kit placement

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Norrblom Petter; [2023]
    Nyckelord :bleeding control; signage; bleeding control kit placement; virtual reality; Stop the Bleed;

    Sammanfattning : Trauma is a leading cause of death, and in potentially preventable trauma deaths insufficient bleeding control has often been noted. For bleeding-related injuries, providing aid quickly is crucial since people may die from haemorrhage within minutes. LÄS MER

  4. 3. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Anton Rolseth; [2023]
    Nyckelord :Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

    Sammanfattning : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. LÄS MER

  5. 4. Biodiversity Monitoring Using Machine Learning for Animal Detection and Tracking

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Qian Zhou; [2023]
    Nyckelord :Small Target Detection; Target Tracking; YOLOv5; DeepSORT; Attention Mechanism; Loss Function; Feature Extraction and Fusion Network; Detektering Av små sål; sålspårning; YOLOv5; DeepSORT; uppmärksamhetsmekanism; förlustfunktion; fusionsnätverk;

    Sammanfattning : As an important indicator of biodiversity and ecological environment in a region, the number and distribution of animals has been given more and more attention by agencies such as nature reserves, wetland parks, and animal protection supervision departments. To protect biodiversity, we need to be able to detect and track the movement of animals to understand which animals are visiting the space. LÄS MER

  7. 5. Evaluation of the challenges and opportunities of Vehicle-to-Grid technology and the potential revenue streams for BEV fleet owners and aggregators

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Lukas Strandberg; Madeleine Sandberg; [2023]
    Nyckelord :Vehicle-to-Grid; Grid flexibility; Capacity markets; Barriers; Fordon-till-nätteknologi; Elnätsflexibilitet; Kapacitetsmarknader; Barriärer;

    Sammanfattning : The increasing amount of renewable energy being connected to the power grid, and the intermittent nature of these resources, calls for increased grid flexibility to ensure operational safety and stability. An effective solution to address this need could be through wider implementation of various energy storage technologies. LÄS MER
