1. 1. Carabidocoenoses and Fragments of Forests : exploring the Carabid Landscape

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Simon Heinrich Arns; [2023]
   Keywords : biodiversity; Carabidae; carabid diversity; entomology; Fragmentation; Fragstats; habitat fragmentation; habitat Heterogeneity; landscape; landscape ecology; landscape Heterogeneity; pitfall trap; quantifying fragmentation;

   Abstract : Epigeic ground beetles (Coleoptera: Carabidae) were sampled between 2021-06-28 and 2021-07-09 using pitfall traps in the Swedish counties Värmland and Gävleborg. The structural properties of the landscapes surrounding these points were estimated from the Swedish Environmental Protection Agency’s national land cover databases and the Swedish Forest Agency’s data for all formally protected and high conservation value forests using patch-based configurational metrics.

3. 2. Analysis of free-riding behaviour using instrumented bicycles

   University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

   Author : Jonathan Johansson; [2023]
   Keywords : Data collection; instrumented bicycle; free-riding; conventional bicycle; electric bicycle; naturalistic data;

   Abstract : The use of bicycle as a transportation mode has increased in popularity during the last four decades. The reasons that could explain why the use of bicycles have increased in popularity are many. READ MORE

4. 3. Characterisation of Ionic Liquid doped Polybenzimidazole Membranes for Application in High-Temperature Proton Exchange Membrane Fuel Cells

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Adam Jacobsson Trönndal; [2023]
   Keywords : Fuel cells; Phosphoric acid; Polybenzimidazole; PA-PBI; Ionic liquid; IL; High temperature proton exchange membrane fuel cell; HT-PEMFC; Electrochemical impedance spectroscopy; EIS; IL-PBI; Chemical engineering; Technology and Engineering;

   Abstract : In this study four membranes were tested and evaluated against each other for use in high-temperature proton exchange membrane fuel cell (HT-PEMFC) applications. A phosphoric acid (PA) doped polybenzimidazole (PBI) membrane, was used as a reference as the current state-of-the-art. READ MORE

5. 4. Machine Learning-based MIMO Indoor Positioning

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Qiyi Chen; [2023]
   Keywords : Technology and Engineering;

   Abstract : The most widely used positioning system is Global Navigation Satellite System (GNSS), which uses traditional positioning techniques and cannot achieve satisfactory positioning performance in indoor scenarios due to Non-Line-of-Sight (NLoS) transmission. Fingerprinting is a non-traditional positioning technique that is robust to NLoS transmission in indoor scenarios. READ MORE

6. 5. Estimating stellar limb darkening using exoplanet transits

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

   Author : Sora Ishida; [2023]
   Keywords : Limb-darkening; CHEOPS; Transit; Exoplanet; PYCHEOPS; Physics and Astronomy;

   Abstract : The brightness of the stars is not uniform over the surface as it varies depending on the wavelength and the atmosphere that the light propagates. Limb darkening is an optical effect caused by a decrease in brightness of the star towards the edge. READ MORE
