  1. 6. Using a GIS to enable an economic, land use and energy output comparison between small wind powered turbines and large-scale wind farms: the case of Oslo, Norway.

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Colin Potter; [2023]
    Keywords : Geography; GIS; Wind power; Renewable energy sources; urban wind energy; urban areas; planning; vertical axis wind turbines; comparative studies; urban integrated energy systems; Oslo; Roan; Earth and Environmental Sciences;

    Abstract : Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale wind turbines on top of buildings within a 2km radius study zone in central Oslo.

  3. 7. Reconstructing Mid-Late Holocene Arctic Climate Using Loess Deposits From Kangerlussuaq, Greenland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : William Mörtsjö Zung; [2023]
    Keywords : ;

    Abstract : The current geological epoch, the Holocene, began 11,700 years ago. During this time, a thermal maximum in temperature was reached somewhere during the early-middle stage at 8-5 kyrs ago which was followed by a period of neoglacial cooling, culminating in the little ice age (LIA).

  4. 8. Experimental Testing of Solar Photovoltaic/Thermal Collectors for Low Temperature Heat Pump Integration

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jaakko Eskola; [2023]
    Keywords : Solar photovoltaic thermal; PVT; heat pump; thermal performance; ISO 9806:2017; Solhybrid; PVT; värmepump; termisk prestanda; ISO 9806:2017;

    Abstract : A hybrid photovoltaic/thermal (PVT) collector enables simultaneous electricity and heat production from a single solar module. Integrating PVT collectors with a ground source heat pump (GSHP) improves the seasonal performance of the heating system and prevents from temperature degradation of the ground. READ MORE

  5. 9. Effects of stratospheric wildfire smoke on ozone depleting substances and ozone levels in the northern midlatitudes

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

    Author : Christopher Grüner; [2023]
    Keywords : Physics and Astronomy;

    Abstract : The goal of this project was to examine whether there are correlations between recent wildfires in the northern hemisphere and stratospheric ozone anomalies in the midlatitudes following the creation of ozone depleting substances. To achieve this goal, data from the Aura satellite's Microwave Limb Sounder instrument was used and processed with self-written Python scripts. READ MORE

  6. 10. TEMPERATURE MODELLING OF GEAR MESH

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Ahsan Kadevalappil Ajilan; [2023]
    Keywords : Helical gear; Power loss; MATLAB; ANSYS; Spiralväxel; Strömförlust; MATLAB; ANSYS;

    Abstract : Temperature control is an essential aspect of gear design. Continuous research is going on to improve the efficiency of gear systems. Power losses or energy losses in these systems typically manifest themselves as increased temperatures and thus reducing the lifetime and overall performance of the system. READ MORE
