  1. 26. Optimizing multigrid smoothers using GLT theory

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematikcentrum

    Author : Denhanh Huynh; [2020]
    Keywords : multigrid; smoothers; GLT; Mathematics and Statistics;

    Abstract : Multigrid algorithms are algorithms used to find numerical solutions to differential equations using a hierarchy of grids of different coarseness. This exploits the fact that short-wavelength components of the solutions converges at a faster rate than the long-wavelength components when using some basic iterative methods, such as the Jacobi method or the Gauss-Seidel method.

  3. 27. Methods to Predict Hull Resistance in the Process of Designing Electric Boats

    University essay from KTH/Marina system

    Author : Felicia Ahlstrand; Elin Lindbergh; [2020]
    Keywords : ;

    Abstract : Combustion engines in boats cause several environmental problems, such as greenhouse gas emissions and acidication of oceans. Most of these problems can be reduced by replacing the combustion engines with electric boats. READ MORE

  4. 28. Component-Based Transfer Path Analysis and Hybrid Substructuring at high frequencies : A treatise on error modelling in Transfer Path Analysis

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : Harikrishnan Venugopal; [2020]
    Keywords : Dynamic Substructuring; Error modelling; Transfer Path Analysis; Uncertainty Propagation; Dynamisk substrukturering; Feluppskattning; Överföringsanalys; Osäkerhetspropagering;

    Abstract : The field of modal testing and analysis is currently facing a surge of interest in error modelling. Several errors which occur during testing campaigns are modelled analytically or numerically and propagated to various system coupling and interface reduction routines effectively. READ MORE

  5. 29. Modelling of Automotive Suspension Damper

    University essay from KTH/Fordonsdynamik

    Author : Saurabh Vyas; Venkata Dinesh Raju Jonnalagadda; [2020]
    Keywords : Damper Model; hysteresis; least squares fitting; Stribeck friction model; Parameterization; FV curve; Damper test rig; Error matrix; Error plots; Multibody Simulation; MBS.; stötdämparmodell; hysteres; minsta kvadratpassning; Stribeck-friktionsmodell; Parametrisering; FV-kurva; stötdämpartestrigg; Felmatris; Feldiagram; Flerkroppssimulering; MBS;

    Abstract : A hydraulic damper plays an important role in tuning the handling and comfort characteristicsof a vehicle. Tuning and selecting a damper based on subjective evaluation, by considering theopinions of various users, would be an inefficient method since the comfort requirements of usersvary a lot. READ MORE

  6. 30. An error assessment of matrix multiplications on posit matrices

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : August Danell Håkansson; Mirja Johnsson; [2020]
    Keywords : Posit; softPosit Library; Moore’s Law; Posit; softPosit; Moores Lag;

    Abstract : The posit is a floating-point number format as proposed by John Gustafson to improve upon the accuracy of the IEEE-754 format, which is the standard today. The goal of this paper was to look specifically at matrix multiplication and examine how the posit format compared to the IEEE-754. READ MORE
