  1. 21. Stability Analysis of Hydrodynamic Performance Indicator Based on Historic Data Sets

    Master-uppsats, Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Författare :Canan Özel Kennedy; [2022]
    Nyckelord :Stability analysis; Anderson-Darling test; Shapiro-Wilk test; curve fitting; Q-Q plot; British Standard BS ISO 19030;

    Sammanfattning : This paper presents a stability analysis of the sensor data which is collected by QTAGG from alarge ocean going ship and using the stability results, introduces some information about howthe measurements that come from the sensors can be improved and how reliable they are. In thetheoretical part, some background information is given mainly based on British Standard(BS)ISO 19030 which was published in November, 2016. LÄS MER

  3. 22. 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

  4. 23. Numerical simulations of pore pressure on concrete buttress dams

    Master-uppsats, KTH/Betongbyggnad

    Författare :Mohammed Abdi; Dimitirios Ntzimanis; [2022]
    Nyckelord :Porepressureanalysis; upliftpressure; buttressdams; drainage; groutcur- tain; rockfractures; damsafety; RIDAS.;

    Sammanfattning : Uplift pressure is one of the most dominant forces on a dam structure. Difference in head water and tail water creates a hydraulic gradient resulting an upward oriented pressure called uplift pressure, which reduces the dam safety against sliding. LÄS MER

  5. 24. Comparative Analysis of Biological Networks by Control Theoretic Methods

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Lea Keller; [2022]
    Nyckelord :;

    Sammanfattning : This project deals with two Goodwin models of circadian rythms and three reduced models in understanding the Belousov-Zhabotinski models of chemical reaction. They are examined and compared by applying dynamical systems theory and control theoretical tools. More precisely, stability analysis of equilibria and the Hopf bifurcations. LÄS MER

  7. 25. Internal stability of geosynthetic reinforced soil walls : Calculations procedures for practical design

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Emil Davidsson; [2022]
    Nyckelord :Geosynthetics; GRS-walls; internal stability;

    Sammanfattning : Reinforced soil constructions have a long history, and various types of the soil reinforcement havebeen in use since the medieval period. Geosynthetic reinforced soil walls (GRS-walls) while beingcommon throughout the world, in not included in the current Eurocode for geotechnical design, SSEN1997-1. LÄS MER
