  1. 1. Measuring copper abundances in the Galactic Bulge

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Nikolei Höglinger; [2024]
    Keywords : Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

    Abstract : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

  3. 2. Exploring the Depth-Performance Trade-Off : Applying Torch Pruning to YOLOv8 Models for Semantic Segmentation Tasks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Xinchen Wang; [2024]
    Keywords : Deep Learning; Semantic segmentation; Network optimization; Network pruning; Torch Pruning; YOLOv8; Network Depth; Djup lärning; Semantisk segmentering; Nätverksoptimering; Nätverksbeskärning; Fackelbeskärning; YOLOv8; Nätverksdjup;

    Abstract : In order to comprehend the environments from different aspects, a large variety of computer vision methods are developed to detect objects, classify objects or even segment them semantically. Semantic segmentation is growing in significance due to its broad applications in fields such as robotics, environmental understanding for virtual or augmented reality, and autonomous driving.

  4. 3. Carbon Capture from Biomass Boiler Flue Gas Emissions using Microalgae : A Case Study

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Graham Kirn; [2023]
    Keywords : ;

    Abstract : Capture and storage of carbon dioxide (CO2) is expected to play an important role in climate change mitigation efforts intended to limit global warming to 1.5 °C. Bioenergy with carbon capture and storage (BECCS), in which carbon is captured during energy generation from sustainably sourced biomass fuels, is of particular interest in Sweden. READ MORE

  5. 4. Computational investigation of the feasibility touse solid neon moderation for GBAR

    University essay from Stockholms universitet/Fysikum

    Author : Lars Gehrmann; [2023]
    Keywords : ;

    Abstract : The main goal of the GBAR (Graviational Behaviour of Antihydrogen at Rest) experiment is to investigatethe gravitational effect on antimatter by measuring the classical free fall of an antihydrogen atom. The requiredpositrons are created by pair production inside a tungsten target and are moderated using a tungsten mesh. READ MORE

  6. 5. Att få politiken på kroken : en etnografisk studie över hur åländska fiskare uppfattar och agerar i sitt yrke

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Anni Holmström; [2023]
    Keywords : småskaligt fiske; Åland; habitus; redovisningskultur; alienation; den gemensamma fiskeripolitiken; säl; förädling;

    Abstract : Fisket har enligt tradition varit viktigt på Åland men är ett yrke som alltmer håller på att försvinna. Ökade utmaningar i form av begränsningar och regelverk, samt miljömässiga faktorer stramar åt fiskarnas olika möjligheter att bedriva deras näring. READ MORE
