  1. 21. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

    University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

    Author : Shivang Parmar; [2023]
    Keywords : Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

    Abstract : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. READ MORE

  3. 22. Major Component Replacement on Floating Wind Turbines

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

    Author : Kilian Galle; [2023]
    Keywords : ;

    Abstract : Among the challenges that floating offshore wind (FOW) energy faces today, operation and maintenanc ecosts, and especially major component replacements (MCR), are an important cost reduction lever. MCRs are defined as any failure on a wind turbine requiring the change of an entire main component of the turbine, such as a gearbox, generator, blade, nacelle, etc. READ MORE

    Keywords : regulation; nuclear energy; energy economics; industrial organization; synthetic control;

    Abstract : Concerns over energy security and climate change are pushing countries to reconsider their stances on nuclear energy and plan new buildouts. The success of nuclear energy has historically varied greatly, depending to a great extent on the legal and regulatory environment. READ MORE

  5. 24. Stochastic Frank-Wolfe Algorithm : Uniform Sampling Without Replacement

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Olof Håkman; [2023]
    Keywords : Stochastic Frank-Wolfe; Stochastic optimization; Sampling without replacement;

    Abstract : The Frank-Wolfe (FW) optimization algorithm, due to its projection free property, has gained popularity in recent years with typical application within the field of machine learning. In the stochastic setting, it is still relatively understudied in comparison to the more expensive projected method of Stochastic Gradient Descent (SGD). READ MORE

  6. 25. Recombinant expression and purification of sugar beet Phytoglobins in Escherichia Coli BL21 (DE3) including metabolic engineering of the heme biosynthesis

    University essay from Lunds universitet/Tillämpad biokemi; Lunds universitet/Beräkningskemi

    Abstract : The protein hemoglobin (Hb) is vital for us humans to ensure enough oxygen replacement in the body. Hb-resembling proteins also exist in plants, these are called phytoglobins (Pgbs). Pgbs are very interesting since they can play a considerable role in the development of blood substitutes and iron supplements for human use. READ MORE
