  1. 6. Aerodynamic Optimization of Low Observable Engine Intake Duct

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Laszlo Vimlati; [2022]
    Nyckelord :NSGA-II; CFD; Air Intake; S-Duct; Optimization; Pressure Recovery; Distortion.; NSGA-II; CFD; Intagskanal; Optimering; Tryckåtervinst; Flödesdistorsion.;

    Sammanfattning : An aerodynamic shape optimization procedure was performed on a low observable engineintake duct. The intake duct was fixed in its throat and aerodynamic interface plane (AIP)sections, while leaving up to 7 design parameters free to deformation in the centroid curveand mid section profile.

  3. 7. Lifecycle Analysis of Forged Products

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mohit Digamber Sakore; [2022]
    Nyckelord :Lifecycle Assessment; LCA; Environmental Product Declaration; EPD; Forged products; Front Axle Beam; Crankshaft; Steering Arm.; Lifecycle Assessment; LCA; Environmental Product Declaration; EPD; Smidda produkter; Framaxelbalk; Vevaxel; Styrarm.;

    Sammanfattning : Sustainability is a major focus for the industry considering the awareness among the public and legislators due to climate change. Automotive manufacturers use many steel products for assembly of vehicles and, many of these products; particularly the heavy and critical components like Front Axle beams and Crankshafts are manufactured using forging process.

  4. 8. Amino Acid Analysis : Establishment of a GC-FID method for Amino Acid Analysis in Legumes

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Ludvig Karlsson; [2022]
    Nyckelord :Amino Acids; GC-FID; Hydrolysis; Legumes; Aminosyror; GC-FID; Hydrolys; Baljväxter;

    Sammanfattning : Demands for plant-based diets sufficient in all required amino acids are increasing due to health and environmental advantages. As legumes offer a complementing source of quality protein to the already heavily consumed cereals, methods for determining amino acid compositions in legumes are needed. LÄS MER

  5. 9. Klimatförbättrad betong : En undersökning kring tillgång och efterfrågan, samt om målet med klimatneutralitet 2045.

    Uppsats för yrkesexamina på avancerad nivå, Mittuniversitetet/Institutionen för ekoteknik- och hållbart byggande

    Författare :Karin Lundqvist; Jeanette Lindkvist; [2022]
    Nyckelord :Hållbart byggande; klimatförbättrad betong; samverkan; betong; Cementa; cement; cementkris; klimatneutral; byggnadsteknik.;

    Sammanfattning : Concrete is a material with attributes that are difficult to replace. However, concrete and cement industries are responsible for as much as 5-8 % of the global emissions. Today, there are solutions to reduce emissions associated with the production of concrete and cement. LÄS MER

  7. 10. Approximating Quasistationary Distributions Using Deep Learning

    Master-uppsats, KTH/Matematisk statistik

    Författare :Björn Wehlin; [2022]
    Nyckelord :Applied Mathematics; Deep Learning; Probability Theory; Stochastic Processes; Ito Diffusions; Quasistationary Distributions; Tillämpad matematik; djupinlärning; sannolikhetsteori; stokastiska processer; Ito-diffusioner; kvasistationära fördelningar;

    Sammanfattning : We study a class of It\={o} diffusion processes on domains with smooth boundary, at which the process is killed. Such a process, when conditioned on non-extinction, gives rise to a stationary state known as a \emph{quasistationary distribution} (QSD). LÄS MER
