  1. 21. Application of new particle-based solutions to the Simultaneous Localization and Mapping (SLAM) problem

    Master-uppsats, KTH/Matematisk statistik

    Författare :Xavier Svensson Depraetere; [2017]
    Nyckelord :;

    Sammanfattning :     In this thesis, we explore novel solutions to the Simultaneous Localization and Mapping (SLAM) problem based on particle filtering and smoothing methods. In essence, the SLAM problem constitutes of two interdependent tasks: map building and tracking. Three solution methods utilizing different smoothing techniques are explored. LÄS MER

    Författare :Måns Tillman; [2017]
    Nyckelord :;

    Sammanfattning : Over the last decades, financial markets have undergone dramatic changes. With the advent of the arbitrage pricing theory, along with new technology, markets have become more efficient. LÄS MER

  4. 23. Training Artificial Neural Networks with Genetic Algorithms for Stock Forecasting : A comparative study between genetic algorithms and the backpropagation of errors algorithms for predicting stock prices

    Kandidat-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Tim Olsson; Konrad Magnusson; [2016]
    Nyckelord :;

    Sammanfattning : Accurate prediction of future stock market prices is of great importance to traders. The process can be automated using articial neural networks. However, the conventional backward propagation of errors algorithm commonly used for training the networks suffers from the local minima problem. LÄS MER

  5. 24. Motion Planning and Stabilization for a Reversing Truck and Trailer System

    Master-uppsats, Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Oskar Ljungqvist; [2015]
    Nyckelord :Truck and trailer; general 2-trailer; modeling; gain scheduling; LQ; Pure pursuit; motion planning; RRT; CL-RRT;

    Sammanfattning : This thesis work contains a stabilization and a motion planning strategy for a truck and trailer system. A dynamical model for a general 2-trailer with two rigid free joints and a kingpin hitching has been derived based on previous work. LÄS MER

  7. 25. An Algorithm for Structural Topology Optimization of Multibody Systems

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Toheed Ghandriz; [2014]
    Nyckelord :Dymola; Abaqus; TOSCA; nonlinear Differential Algebraic Equation; finite element method; flexible body; SIMP; dynamic body; Topology Optimization of Multibody Systems; flying element; Technology and Engineering;

    Sammanfattning : Topology Optimization (TO) of static structures with fixed loading is a very interesting topic in structural mechanics that has found many applications in industrial design tasks. The extension of the theory to dynamic loading for designing a Multibody System (MBS) with bodies which are lighter and stronger can be of high interest. LÄS MER
