  1. 1. Navigation with variable point of reference for 3DOF differential drive mobile robot

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Adlerteg Casper; Sen Adem; [2021]
    Nyckelord :differential drive robot;

    Sammanfattning : In this thesis, a kinematic model for controlling an Omni-directional 3 DOF DDR with an external navigation point is presented. Two different dynamic models for investigating the resulting torque on the three active motors on the robot are also developed and validated. LÄS MER

  3. 2. Evaluating the Practicality of Using a Kronecker-Factored Approximate Curvature Matrix in Newton's Method for Optimization in Neural Networks

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

    Författare :Magnus Tornstad; [2020]
    Nyckelord :;

    Sammanfattning : For a long time, second-order optimization methods have been regarded as computationally inefficient and intractable for solving the optimization problem associated with deep learning. However, proposed in recent research is an adaptation of Newton's method for optimization in which the Hessian is approximated by a Kronecker-factored approximate curvature matrix, known as KFAC.

  4. 3. Beräkningsmetoder för Molekylsimuleringar

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

    Författare :Viktor Sandström; [2019]
    Nyckelord :;

    Sammanfattning : Denna avhandling handlar om beräkningsmetoder för att utföra molekylsimuleringar på ett system av enkla partiklar. Genom att använda Lennard-Jones parpotential kan den attraktiva-repulsiva kraften som verkar på atomer och molekyler modelleras. LÄS MER

  5. 4. Suturing in Surgical Simulations

    Master-uppsats, KTH/Numerisk analys, NA

    Författare :Kiran Beersing-Vasquez; [2019]
    Nyckelord :Surgical suturing; spline model; Lagrange constraints; multibody dynamics; differential algebraic equations; Kirurgisk suturering; spline-modell; Lagrange-begränsningar; multikroppsdynamik; differentiella algebraiska ekvationer;

    Sammanfattning : The goal of this project is to develop virtual surgical simulation software in order to simulate the suturing and knot tying processes associated with surgical thread. State equations are formulated using Lagrangian mechanics, which is useful for the conservation of energy. LÄS MER

  7. 5. Non-linear Curve Fitting

    Magister-uppsats, Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Författare :Farhad Morad; [2019]
    Nyckelord :Curve Fitting; Power-exponential function; Gauss-Newton algorithm; Levenberg-Marquardt algorithm; Linear and non-linear curve fitting; Kurvanpassning; Potens-exponential funktion; Gauss-Newton-algoritm; Levenberg-Marquardt-algoritm; Linjär och ickelinjär kurvanpassning;

    Sammanfattning : The work done in this thesis is to examine various methods for curve fitting. Linear least squares and non-linear least squares will be described and compared, and the Newton method, Gauss--Newton method and Levenberg--Marquardt method will be applied to example problems. ..
