  1. 1. Optical Communication using Nanowires and Molecular Memory Systems

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

    Author : Thomas Kjellberg Jensen; [2024]
    Keywords : neuromorphic computing; nanowire; molecular dye; DASA photoswitch; OBIC; Physics and Astronomy;

    Abstract : Neuromorphic computational networks, inspired by biological neural networks, provide a possible way of lowering computational energy cost, while at the same time allowing for much more sophisticated devices capable of real-time inferences and learning. Since simulating artificial neural networks on conventional computers is particularly inefficient, the development of neuromorphic devices is strongly motivated as the reliance on AI-models increases.

  3. 2. Bivänliga växter i urban miljö : en granskning av växtutbudet från landskapsarkitektprogrammet

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

    Author : Emma Asker Kling; Katarina Enskog Gripenvik; [2023]
    Keywords : Bin; humlor; vildbin; pollinatörer; pollinering; urban miljö; växtkännedom; ekosystemtjänst;

    Abstract : Pollinatörerna är hotade globalt och i det svenska landskapet, och behöver hjälp för att överleva (Naturvårdsverket u.å.b). Den främsta orsaken till den negativa utvecklingen är förlusten och fragmenteringen av pollinatörernas livsmiljöer (Naturvårdsverket u. READ MORE

  4. 3. Förhållanden för pollination i rödklöver; konstant eller tidsbunden variation? : undersökning av tidpunktens inflytande över variation i pollinering och frösättning hos Trifolium pratense L.

    University essay from SLU/Dept. of Plant Protection Biology

    Author : Helena Carlsson; [2023]
    Keywords : Rödklöver; Trifolium pratense; pollination; frösättning; Bombus;

    Abstract : Frösättning i klöver (Trifolium pratense L.) är i majoritet av moderna kommersiellt odlade sorter högt varierande och ger en opålitlig och osäker produktion. READ MORE

  5. 4. Pollinator communities on a landscape complexity gradient in southern Sweden

    University essay from SLU/Dept. of Ecology

    Author : Hanna Olsson; [2023]
    Keywords : pollinator; bumblebee; rough pasture; semi-natural pasture; unimproved grazing; landscape complexity;

    Abstract : Investigating how pollinator populations are affected by land use changes is crucial for predicting their persistence in the landscape and thereby the persistence of the significant service they provide to crop production. Pollinator populations are subjected to multiple threats, particularly overall intensification of cropping systems and landscape simplification. READ MORE

  6. 5. Competition between managed honeybees and wild bumblebees - Quantifying dietary overlap in semi-natural grasslands

    University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Emma Rosberg; [2023]
    Keywords : Earth and Environmental Sciences;

    Abstract : The decline of bees, such as bumblebees, over the last decades raises concerns as they are key pollinators in both agricultural and natural ecosystems. One proposed cause for the decline of wild bees is competition for food resources with managed honeybees. READ MORE
