  1. 1. Jet fragmentation in shaped charges

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Joakim Ericson; [2022]
    Nyckelord :Shaped charges; numerical simulation; jet fragmentation; Riktad sprängverkan; numerisk simulering; strål-fragmentering;

    Sammanfattning : This master thesis treats the numerical simulation of shaped charge jets and its fragmentation process. Shaped charges is a method to concentrate the effect of an explosive charge and penetrate deeply into a target due to a the formation of a jet with great penetration capabilities. LÄS MER

  3. 2. Quantification of I-131 Activity from Gamma Camera Images of Thyroid Cancer Patients

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Frida Westerbergh; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : BACKGROUND: Radioiodine (131I) has been used in thyroid cancer treatments for many years, and has demonstrated good results with regards to disease management. Radioiodine therapy is however partially empirical, as not very much is known concerning radiation dosimetry. LÄS MER

  4. 3. Study and Analysis of Asymmetrical Charging as A New Electrical Vehicle (EV) Smart Charging Method

    Master-uppsats, KTH/Energiteknik

    Författare :Rosyadi Sahilaushafnur; [2019]
    Nyckelord :;

    Sammanfattning : Currently, the proliferation of electrified vehicles (EV) has increased rapidly. Considering EV users’ point of view, the duration of charging, and the place to charge their car are essential factors. Increase of EV penetration gives also impact on the electrical network such as overloading, and power quality issues. LÄS MER

  5. 4. What If We Tilt the AOD? : Developing a numerical and physical model of a downscaled AOD converter to investigate flow behaviour when applying an inclination.

    Master-uppsats, KTH/Materialvetenskap

    Författare :Serg Chanouian; [2019]
    Nyckelord :AOD; inclination angle; penetration depth; mixing time;

    Sammanfattning : In a scrap based stainless steel plant the dominant process for carbon reduction is the Argon oxygen decarburisation process (AOD). The process goes through three steps: decarburisation, reduction and desulphurisation where the main challenge is to oxidise carbon to CO without oxidising the expensive chromium. LÄS MER

  7. 5. Assessment of using liquidity index for the approximation of undrained shear strength of clay tills in Scania

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Dagnija Andreasson; [2019]
    Nyckelord :clay till; undrained shear strength; liquidity index; CPT; Earth and Environmental Sciences;

    Sammanfattning : Undrained shear strength is a crucial parameter of the clay-rich sediments commonly used in the design process of geotechnical structures and is determined by several tests. As a considerable part of these tests are cost- and time consuming, it is of interest to investigate the potential relationship with shear strength (cu) with alternative, easily measurable parameters, such as liquidity index (IL).
