1. Dynamic simulation of Swedish residential building renovations and its impact on the district heating network
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : As urbanization continues to rise, cities now account for two-thirds of the world's total energy consumption. The built environment alone contributes to 40% of total energy consumption and a third of total greenhouse gas emissions. With an additional 2. LÄS MER
2. Åldring av högtranslucent zirkoniumdioxid (3Y-TZP) i munmiljö jämfört med artificiella åldringsmetoder. En pilotstudie. : Aging of high translucent zirconium dioxide (3Y-TZP) in the oral environment compared to artificial aging methods. A pilot study.
Kandidat-uppsats, Malmö universitet/Odontologiska fakulteten (OD)Sammanfattning : Sammanfattning Syfte Syftet med pilotstudien var att utvärdera hur kristallfaserna i högtranslucent zirkoniumdioxid (3Y-TZP) påverkas av åldring i munmiljö (in-vivo-metod) och in-vitro-metoder för artificiellt åldrande: vattenförvaring, termocykling och autoklavering. Material och metod Totalt framställdes 16 provkroppar av högtranslucent zirkoniumdioxid (3Y-TZP) med slutmått på 1 mm i tjocklek och 5 mm i diameter. LÄS MER
3. Comparing the Effects of Flexibility Options on Conventional and Low-temperature District Heating Networks : Studying the potential of the next generation of district energy systems
Master-uppsats, KTH/EnergiteknikSammanfattning : District heating (DH) systems have been commonplace in Europe for over a century. These systems have undergone an evolution since their conceiving, and today we are at the precipice of the next major transition from the third-generation district heating system (3GDH) to the fourth generation (4GDH).

4. Heat dissipation due to microvibrations in low temperature experiments
Master-uppsats, KTH/FysikSammanfattning : Ultra-sensitive photodetectors on-board space missions need very low temperatures to keep a good resolution. Cryo-coolers, such as pulse-tubes, help maintaining these conditions within a cryostat. In return however, they generate micro-vibrations. LÄS MER
5. Review and Design Adaptations of a SrCl2-NH3 bench-scale Thermochemical Heat Storage system
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Thermochemical heat storage (TCS) is a thermal energy storage (TES) technology used to store thermal energy for later use. TCS can provide heating or cooling services from intermittently available thermal energy, often low grade waste heat. LÄS MER
