  1. 1. Interaction for flexural column buckling : Analytical procedures compared with FE-simulations

    University essay from KTH/Bro- och stålbyggnad

    Author : Noah Norberg; [2023]
    Keywords : ;

    Abstract : This master's thesis presents a study on the stability of steel structures under flexural bucklingconstraints. The study focuses on the interaction and behaviour of flexural buckling formulas in SSEN-1993-1-1 and Swedish BSK and the performance of actual structural members subjected to suchconstraints.

  3. 2. Modeling of a ball contact with a coated plate

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

    Author : Mohammadreza Saeedi; [2023]
    Keywords : Pin on disc tribometer; coating; contact mechanics; finite element method; tribology; Pin on disc tribometer; beläggning; kontaktmekanik; finita elementmetod; tribologi;

    Abstract : During tightening of a screw, the variation in friction will affect the force acting on the joint, especially when tightening using torque as a control parameter. So, it is crucial to have a proper understanding of the contact mechanism and friction in the screw head to joint and thread interfaces. READ MORE

  4. 3. Designing a New SPS Injection System With Numerical Optimisation

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Elias Waagaard; [2022]
    Keywords : Hierarchical optimisation; injection system; kicker magnet; septa; genetic algorithms;

    Abstract : The Super Proton Synchrotron (SPS) injection system plays a fundamental role to preserve the quality of injected high-brightness beams for the LHC physics program and to maintain the maximum storable intensity. The present set-up is the result of years of upgrades and patches of a system that was not conceived for such intensities and beam qualities. READ MORE

  5. 4. Internal stability of geosynthetic reinforced soil walls : Calculations procedures for practical design

    University essay from KTH/Jord- och bergmekanik

    Author : Emil Davidsson; [2022]
    Keywords : Geosynthetics; GRS-walls; internal stability;

    Abstract : 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. READ MORE

  6. 5. Confounder Parsing for Text Matching

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Jannes Reichl; Johan Rönkkö; [2021-07-06]
    Keywords : Text matching; confounder parsing; causal inference; covariate balance; International Monetary Fund; policy evaluation;

    Abstract : In observational studies for policy evaluation, matching is used in service of causal inference to simulate randomization and thus reduce selection bias that might occur when treatment assignment differs systematically. This is done by balancing the distribution of confounding covariates measured before treatments. READ MORE
