  1. 6. Learning-Based Motion Planning and Control of a UGV With Unknown and Changing Dynamics

    University essay from Linköpings universitet/Reglerteknik

    Author : Åke Johansson; Joel Wikner; [2021]
    Keywords : machine learning; model predictive control; motion planning; Bayesian linear regression; motion primitives; input sampling; hybrid A*;

    Abstract : Research about unmanned ground vehicles (UGVs) has received an increased amount of attention in recent years, partly due to the many applications of UGVs in areas where it is inconvenient or impossible to have human operators, such as in mines or urban search and rescue. Two closely linked problems that arise when developing such vehicles are motion planning and control of the UGV. READ MORE

  3. 7. Active fund management or passive index cruising?

    Keywords : CIGS; ZnO; ZnMgO; solar cells; thin film; zinc oxide; window layer; ALD; PVD;

    Abstract : Two identified setbacks for CIGS based devices in order to obtain higher efficiency are parasitic absorption in the window layer structure and losses in open-circuit voltage due to bad interfaces. This study investigated how the performance of the solar cell is affected by depositing intrinsic ZnO (i-ZnO) and ZnMgO with atomic layer deposition (ALD) instead of the conventional sputtering.
