  1. 1. Hårfällor för järv : en studie i alternativa inventeringsmetoder

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Tove Hydén; [2023]
    Nyckelord :järv; inventering; stora rovdjur; DNA; DNA-inventering; hårfälla;

    Sammanfattning : Järv är ett mytomspunnet djur som vi vet relativt lite om i jämförelse med andra stora rovdjur. Järven tillhör mårddjuren och har en cirkumpolär utbredning i Europa, Asien och Nordamerika. i Skandinavien förekommer den främst kring fjällkedjan men utbredningsområdet ökar. LÄS MER

  3. 2. Monitoring of heat exchanges in thesnowpack of Foxfonna glacier, Spitzbergen,Svalbard.

    Kandidat-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :Thibault Desjonquères; [2022]
    Nyckelord :Glaciers; Glaciology; Svalbard; Geophysics; Superimposed Ice; Foxfonna; Geology.; Physics and Astronomy;

    Sammanfattning : The processes of meltwater storage in firn and the impact of refreezing on firn-coveredglaciers have been investigated on the Greenland ice-sheet. On Svalbard, climate changepromotes the disappearance of firn on glaciers. LÄS MER

  4. 3. Off-road Driving with Deteriorated Road Conditions for Autonomous Driving Systems

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Eric Ekström; [2022]
    Nyckelord :autonomous driving systems; computer graphics; synthetic training data; driving;

    Sammanfattning : Recent studies on robustness of machine learning systems shows that today’s autonomous vehicles struggle with very basic visual disturbances such as rain or snow. There is also a lack of training data that includes off road scenes or scenes with different forms of deformation to the road surface. LÄS MER

  5. 4. Fragmentation in graupel snow collisions

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Martanda Gautam; [2022]
    Nyckelord :Ecosystem Analysis; Clouds; Snow; Graupel; SIP; Fragmentation; CKE; Rime Fraction; Earth and Environmental Sciences;

    Sammanfattning : Aircraft observations of precipitating clouds with cloud top temperatures higher than -38°C have revealed that Secondary Ice Production (SIP) is responsible for presence of majority of ice particles. One such SIP mechanism is fragmentation via collisions between ice particles. LÄS MER

  7. 5. Building with pollution

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Zornitsa Hristova Kovacheva; [2021]
    Nyckelord :Arts and Architecture;

    Sammanfattning : Black carbon is an ever-growing global problem and one of the most important environmental issues of this generation. Black carbon, also known as soot, is a highly polluting substance and it is the second-largest polluter after carbon dioxide. LÄS MER
