  1. 11. Evaluation of water stress mapping methods in vineyards using airborne thermal imaging

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alon Zuta; [2020]
    Keywords : Geography; Geographical information systems; GIS; Remote sensing; Cover crop; Thermal imaging; Spatial variability; vineyards; interpolation; water stress index; CWSI; Ig; stem water potential; UAV; Rheingau; Interpolation.; Agriculture and Food Sciences; Biology and Life Sciences; Technology and Engineering; Earth and Environmental Sciences;

    Abstract : With low cost and high efficiency, use of airborne infrared thermography imaging from an unmanned aerial vehicle (UAV) has become a widely used technique to measure plant water stress. With that, the use of UAV mounted thermal camera as a precision agriculture technique to map crop water stress is not trivial and its success is depended on variety of factors which are still needed to be studied and understood.

  2. 12. Field damage investigation and evaluation of numerical model using the collected data at Kemi Mine

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Heidi Rikberg; [2019]
    Keywords : Rock mechanics; field damage investigation; damage mapping; evaluation; numerical model; mining;

    Abstract : This Master´s Thesis studies the applicability of existing numerical model to predict the conditions in the drifts at the mine. Damage mapping, covering the existing production levels, has been carried out to study the condition of the surface support, i.e. READ MORE

  3. 13. People’s perception of seagrass ecosystems - a Step Zero analysis in establishing marine protection of seagrass around Gotland, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sofie Elggren; [2019]
    Keywords : Sustainable development; seagrass; ecosystem services; participation; natural resource management; Step Zero analysis;

    Abstract : The marine environment is under stress. This study will address seagrass around the island of Gotland, Sweden. Seagrass is a marine flowering plant which grows on the seabed and provide a multitude of important ecosystem services such as nutrient cycling, carbon sequestration, erosion mitigation and serve as habitats for primary fisheries.

  4. 14. Modelling the influence of porosity on fatigue strength of sintered steels

    University essay from Uppsala universitet/Strukturkemi

    Author : Emily Hall; [2019]
    Keywords : Fatigue; Powder metallurgy; PM; sintered steels; fracture mechanics; porosity; metal powders; fatigue strength; fatigue limit; utmattning; pulvermetallurgi; metallpulver; utmattningsgräns; brottmekanik; porositet; sintring;

    Abstract : The pores in pressed and sintered components constitute weak points in the material since the stress concentration is larger than the nominal stress there. Therefore, fatigue cracks initiate at the pores. Specifically, it can be assumed that the fatigue cracks initiate at the largest pore in the stressed volume. READ MORE

  5. 15. Urban grönstruktur och hälsa : en systematisk litteraturstudie av kvalitetsaspektens betydelse och relevans

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

    Author : Agnes Kyrö; Julia Åstrand; [2019]
    Keywords : urban grönstruktur; urban hälsa; kvalitet; mental hälsa; fysisk hälsa;

    Abstract : Det finns i dagsläget många studier som visar på en koppling mellan urban grönstruktur och positiva hälsoeffekter men trots att forskningen gällande dessa hälsoeffekter ökar, behandlar de flesta studierna fortfarande urbana grönområden som en homogen massa. Det finns alltså fortfarande en kunskapslucka gällande huruvida någon speciell egenskap och/eller kvalitetsaspekt av grönstruktur genererar bättre eller sämre effekter sett till hälsa. READ MORE
