  1. 36. Fine-Tuning Parameters in CT

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Anton Adelöw; Tomas Nordström; [2023]
    Nyckelord :;

    Sammanfattning : Computed tomography (CT) is a medical imaging technique that usesX-rays to obtain a reconstruction of an object. The term acquisition ge-ometry refers to the arrangement of imaging sensors and the X-ray sourceas well as the procedure used for data collection. LÄS MER

  3. 37. Gromov-Witten invariants via localization techniques

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Noah Dizep; [2023]
    Nyckelord :Gromov-Witten invariants; enumerative geometry; string theory;

    Sammanfattning : Gromov-Witten invariants play a crucial role in symplectic- and enumerative Geometry as well as topological String Theory. Essentially, theseinvariants are a count of (pseudo)holomorphic curves of a given genus,going through n-marked points on a symplectic manifold. LÄS MER

  4. 38. Efficient FE Modeling of Large Casted Parts

    Master-uppsats, KTH/Maskinkonstruktion

    Författare :Lalitha Swetha Amirapu; Haswanth Yalamanchili; [2023]
    Nyckelord :FE modeling; Large casted parts; Meshing techniques; Mid-surface modeling; FE-modellering; Stora gjutna delar; Meshing-tekniker; Mid-Surface modellering;

    Sammanfattning : The design and analysis of large casted parts present significant challenges due to their complex geometry. Finite Element (FE) modeling is a vital tool for understanding the performance of casted components. However, the computational requirements associated with these parts often lead to excessive processing times and resource utilization. LÄS MER

  5. 39. Automation of a rotating bed reactor for PFAS remediation

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Axel Martin; [2023]
    Nyckelord :Programming; automation; experimentation; optimization;

    Sammanfattning : Properties such as being water and oil repellent and being heat resistant make per- and polyflouroalkyl substances (PFAS) useful in a wide range of products. Since they do not break down in the environment, PFAS pollution makes it way back into drinking water and seafood. LÄS MER

  7. 40. The effect of nozzle geometry on bubble formation : Physical modeling by air in a water tank

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

    Författare :Mhd Osman Bernieh; [2023]
    Nyckelord :Nozzle geometry; bubble formation; water tank model; bubble flow; Munstycksgeometri; bubbelbildning; vattentankmodell; bubbelflöde;

    Sammanfattning : The bubble flow is used for different application in steel production and refining processes. It plays in indispensable role in the ladle refining process such as for homogenization and inclusion removal. Hence, it is important to understand the effect of the nozzle outlet geometry on the bubble formation. LÄS MER
