  1. 1. Braids and configuration spaces

    University essay from Uppsala universitet/Geometri och fysik

    Author : Andersson Rasmus; [2023]
    Keywords : braids; braid groups; configuration space; algebraic topology; group theory; fundamental group; covering spaces;

    Abstract : A configuration space is a space whose points represent the possible states of a given physical system. As such they appear naturally both in theoretical physics and technical applications. READ MORE

  3. 2. Theories with higher-order time derivatives and the Ostrogradsky ghost

    University essay from Stockholms universitet/Fysikum

    Author : Eleonora Svanberg; [2022]
    Keywords : Ostrogradsky ghost; higher-order time derivatives theories; Lagrangian mechanics; mathematical physics; Hamiltonian formalism;

    Abstract : Newton's second law, Schrödinger's equation and Maxwell's equations are all theories composed of at most second-time derivatives. Indeed, it is not often we need to take the time derivative of the acceleration. READ MORE

  4. 3. The Ratio of Reality : A study of the gyromagnetic ratio in theories ranging from classical mechanics to string theory

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Daniel Nilsson; [2021]
    Keywords : Quantum field theory ; String theory ; Dirac equation ; Dirac theory ; Dirac; gyromagnetic; ratio; g-factor; Kvantfältsteori; strängteori; Dirac; g-factor; gyrmagnetisk kvot ;

    Abstract : In this project a theoretical study of the so called gyromagnetic ratio was done by investigating classical mechanics, Dirac theory and string theory. The gyromagnetic ratio is a constant term appearing in the coupling between angular momentum and magnetic moment for a particle. READ MORE

  5. 4. Dynamics of a complex mechanical pendulum : and its dependence on energy

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Niclas Löfvenmark; [2021]
    Keywords : ;

    Abstract : In this thesis we analyze the motion of the double pendulum in which the first rod has a distributed mass and the second is a light rod with a linked spring attached to a point mass. The dynamics of the system is modelled in Maple using the Sophia package and Lagrangian mechanics. Trajectories, phase portraits, conservation of energy etc. READ MORE

  6. 5. Object Tracking Achieved by Implementing Predictive Methods with Static Object Detectors Trained on the Single Shot Detector Inception V2 Network

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Richard Dan William Barkman; [2019]
    Keywords : Supervised Machine Learning; Hyperparameter Optimisation; Convolutional Neural Networks; Lagrangian Mechanics; Predictive Methods;

    Abstract : In this work, the possibility of realising object tracking by implementing predictive methods with static object detectors is explored. The static object detectors are obtained as models trained on a machine learning algorithm, or in other words, a deep neural network. READ MORE
