  1. 1. Establishing High-Temperature Models for Leakage Current in Gated Lateral Bipolar Junction Transistors

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Jimmy Atterstig; [2024]
    Keywords : Electronics; leakage current; brokaw bandgap; semiconductor physics; gauss-newton;

    Abstract : Power-efficient circuits are a vital step in moving towards a greener future. Battery life can get substantially improved by decreasing the amount of power a circuit needs. Lower power also leads to less excess heat generated. READ MORE

  3. 2. Solar Photovoltaic Fire Risks : FE-analysis of fire exposed solar photovoltaic systems and comparison of current legislation and recommendations from different countries

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Elin Bergroth; Greta Torstensson; [2023]
    Keywords : Solar Photovoltaic; National Guidelines; Fire Department; FE-analysis; TASEF; Solceller; Nationella Riktlinjer; Räddningstjänst; FE-analys; TASEF;

    Abstract : The global use of energy increases every day and to meet the growing demand, energy sources are constantly being developed to become more efficient and reliable. During the last decade, the global solar photovoltaics (PV) capacity has increased every year and in 2017, solar PV was the global leading power source of renewable energy. READ MORE

  4. 3. Sustainable water treatment in the manufacturing industry : Investigation of the water treatment system at VCE, Hallsberg

    University essay from Linköpings universitet/Energisystem

    Author : Johan Hagströmer; Forsberg Emma; [2023]
    Keywords : ;

    Abstract : Transitioning to circular flows is essential to economize the planet’s resources. One of the most important resources on earth is water as it is vital for all living things. However, water purification methods have proven to be very energy intensive, and increasing the circular water flows is therefore challenging. READ MORE

  5. 4. HEAT CONSUMPTION OPTIMIZATION IN 4TH GENERATION DISTRICT HEATING : Study on utilizing low temperature heat sources and heat stored in a house by varying indoor temperature

    University essay from Mälardalens universitet/Framtidens energi

    Author : Simon Karlsson; Farman Farman; [2023]
    Keywords : 4th Generation District Heating; Heat Pumps; Thermal Energy Storage; Optimization; Low Temperature Heat Sources; Thermal Inertia;

    Abstract : 4th generation district heating (4GDH) and varying the indoor temperature to store heat are both important concepts that can make it easier to implement more renewable energy and reduce costs of heating. This study looks at these concepts from a customer perspective using one building and looking at how energy can be stored and the performance of 4GDH. READ MORE

  6. 5. Heat recovery from vacuum brazing furnaces

    University essay from Lunds universitet/Avdelningen för Installations- och klimatiseringslära

    Author : Oliver Robertsson; Rasmus Wikman; [2023]
    Keywords : Waste heat; Vacuum furnace; Heat recovery; HVAC; Technology and Engineering;

    Abstract : By partly replacing the use of primary energy sources with waste heat recovery, climate and environmental goals for the future will be closer at hand. This thesis investigates the waste heat potential of Alfa Laval's vacuum brazing furnaces in Ronneby and alternative ways of integrating the furnace's waste heat into the building's HVAC system.
