    • Simulation of manure resource recovery plant 

      Hussain, Shahid (Master thesis, 2015-09-18)
      The Bio Win software was used to simulate manure feeding to a separator, anaerobic digester (AD) and activated sludge (AS) nitrification reactor system. The General Bio Win model called integrated AS/AD model was capable ...
    • Simulation of oil production and CO₂ 

      Furuvik, Nora Cecilie Ivarsdatter (Master thesis, 2016)
      Deep geologic injection of supercritical carbon dioxide (CO₂) for enhanced oil recovery (EOR), plays an important role in the sequestration of CO₂ to minimize the impact of CO₂-emissions due to global warming. CO₂-EOR ...
    • Simulering av CO2-fjerning med aminer 

      Moholt, Bjørn (Master thesis, 2010-08-26)
      Gasskraftverk produserer store mengder CO2, og det er ønskelig å unngå utslipp av CO2 til atmosfæren. Skagerak Energi AS har planer om et gasskraftverk med CO2-fjerning i Grenlandsområdet. Det er utført simuleringer ...
    • Software Testing, Data Security and GDPR 

      Agbamoro, Michael (Master thesis, 2019)
      Software and data security are an important part of a modern-day business strategy of any organization as it forms the basis for guaranteed security of information, data, and assets of any organization. This project is ...
