  1. 1. Effects of Dynamic Modeling on the Path Planning of Simulated Autonomous Vehicles

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

    Författare :Elin Kidell Löwstedt; [2022]
    Nyckelord :;

    Sammanfattning : The purpose of the thesis was to evaluate the robustness of the Hybrid A* algorithm in regards to the levels of dynamic vehicle modeling, vehicle parameters and driving velocity. The original scope of the thesis project was to alter vehicle and tire models but this was discovered to be out of the time limits of the thesis project. LÄS MER

  3. 2. Path planning for autonomous vehicles using clothoid based smoothing of A* generated paths and optimal control

    Master-uppsats, KTH/Numerisk analys, NA

    Författare :Marcus Lundberg; [2017]
    Nyckelord :;

    Sammanfattning : Autonomous vehicles is a rapidly expanding field and the need for robust and efficient path planners is high. We approach the global path- planning problem for an autonomous load carrier for quarry environments, developed at Volvo Construction Equipment, using two methods: a two- step path planning and path smoothing approach, and a method based on an optimal control formulation of the path planning problem.

  4. 3. Planning semi-autonomous drone photo missions in Google Earth

    Kandidat-uppsats, Mittuniversitetet/Avdelningen för data- och systemvetenskap

    Författare :Per Johan Fredrik Nilsson; [2017]
    Nyckelord :Google Earth; Robotics; Pathfinding; A*; Theta*; Path smoothing; Traveling Salesman Problem; Branch-and-Bound; Swift; C ;

    Sammanfattning : This report covers an investigation of the methods and algorithms required to plan and perform semi-autonomous photo missions on Apple iPad devices using data exported from Google Earth. Flight time was to be minimized, taking wind velocity and aircraft performance into account. LÄS MER

  5. 4. Optimal Path Smoothing using Clothoids for Autonomous Vehicles in the Quarry Environment

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Anda Zhang; [2017]
    Nyckelord :;

    Sammanfattning : Autonomous vehicles are a rapidly growing field and will play an important role in future society. The introduction of autonomous machines in the quarry environment increases safety in the hazardous working conditions and reduces the risk of accidents caused by human error. LÄS MER

  7. 5. Firm Financing and Accounting Discretion: A study of income smoothing in Sweden

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Författare :Emil Ericson; Erik Rasmusson; [2014]
    Nyckelord :Income Smoothing; Earnings Smoothing; Accounting Discretion; Trade Credit; Insider Ownership;

    Sammanfattning : Income smoothing is the reduction of inter-temporal variation in earnings. A smooth earnings path has been documented as an important consideration for managers. This study investigates the relationship between a firm's sources of financing and the use of accounting discretion for income smoothing. LÄS MER
