  1. 1. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Franz Wikner; [2024]
    Nyckelord :Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

    Sammanfattning : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.

  3. 2. SOLAR WIND HEATING OBSERVED BY SOLAR ORBITER

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Karan Pal; [2023]
    Nyckelord :;

    Sammanfattning : In this project, we investigate the plasma heating associated with coherent structures, such as current sheets and vortices, in different solar wind conditions: slow solar wind, stream interaction regions, and heliospheric current sheets, observed by the Solar Or- biter mission. To unravel this mystery, we first use the Partial Variance of Increment method [1] to locate these coherent structures. LÄS MER

  4. 3. Reprocessing weather data from Smart Stake weather stations on the Greenland ice sheet

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Leon Lovén; [2023]
    Nyckelord :ice sheet; data processing; weather station; Greenland; GEUS; Smart Stake; istäcke; databehandling; väderstation; Grönland; GEUS;

    Sammanfattning : To identify a climate trend, a lot of data is required for the conclusion to be accurate. A trend can require 30 years worth of measurements in order to say anything with certainty about how the climate is changing. It is therefore important to utilize every source of data in climate research. LÄS MER

  5. 4. Plant community responses to 15 years of nitrogen and phosphorus fertilization along an elevational gradient in the subarctic tundra

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Gaya Ten Kate; [2023]
    Nyckelord :arctic tundra; climate change; fertilization; nitrogen; phosphorus; plant community composition; species richness; Simpson’s diversity; Shannon-Wiener diversity; elevational gradient;

    Sammanfattning : Climate change in the Arctic has profound effects on tundra vegetation, directly through increasing temperatures and indirectly through changes in plant community composition and nutrient cycling. Fertilization experiments are widely used to study the effects of increased nutrient availability on arctic tundra vegetation. LÄS MER

  7. 5. Assessing the Impacts of Climate Change and Water Scarcity on Agricultural Practices in Kenya -Implications for Adaptation Strategies

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

    Författare :Sanjina Rahi Oishee; [2023]
    Nyckelord :Climate Change; Agriculture; Temperature; Precipitation; Water Scarcity; Agro-Climatic Zone; Earth and Environmental Sciences;

    Sammanfattning : Like other African countries, Kenya’ economy and food security is heavily dependent on agriculture. Climate change has led to variability in temperature and precipitation, and extreme weather events such as droughts and floods, all of which can significantly impact crop productivity and food security in the long-term.
