  1. 21. Development of Test Rig and Experimental Evaluation of Hydrostatic Bearings for an Axial Flux Machine

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Amir Avdic; Kishore-Babu Vejendla; [2022]
    Keywords : viscous losses; hydrostatic bearing; hydrodynamics; thin oil film.; Viskösa förluster; generator; hydrostatiska lager; hydrodynamik; tunn oljefilm.;

    Abstract : A novel electric machine design, similar to an axial flux machine, incorporates hydrostatic bearings to increase efficiency and stability of said machine. In this thesis, the feasibility of a hydrostatic solution is explored and evaluated by development, manufacturing, and assembly of a test rig, as well as running experimental tests with it.

  3. 22. Integration of Hydrogen Production via Water Electrolysis at a CHP Plant : A feasibility study

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Anton Ottosson; [2021]
    Keywords : Electrolyzer; Energy; CHP; Hydrogen; Feasibility; PEM; water electrolysis; Elektrolysör; Energi; CHP; Vätgas; PEM; vattenelektrolys;

    Abstract : Hydrogen gas (H2), that is not produced from fossil oil or natural gas, is expected to become a cornerstone in the energy transition strategy in Europe. The recent years, technological and economic advances in the electrolyzer area, along with political and corporate support, have put H2 at the forefront of many countries’ climate change agenda.

  4. 23. How do situational factors influence performance? Regulatory focus and handball penalty taking at a World Cup stage

    University essay from Högskolan i Halmstad/Akademin för hälsa och välfärd

    Author : Anton Melin; [2021]
    Keywords : pressure; performance; promotion; prevention; regulatory fit; regulatory focus;

    Abstract : Pressure-performance relationship in sport situations was investigated within a self-regulatory focus framework (regulatory focus theory; Higgins, 1997). To that end, the role of regulatory fit in different ecologically valid handball penalty situations taken in the 2021 World Cup was examined. READ MORE

  5. 24. Controlling a Hydraulic System using Reinforcement Learning : Implementation and validation of a DQN-agent on a hydraulic Multi-Chamber cylinder system

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : David Berglund; Niklas Larsson; [2021]
    Keywords : Gear selection; reinforcement learning; machine learning; DQN; neural network; multi chamber cylinder; Digital hydraulics; hydraulics; Matlab; Simulink; Hopsan; hydraulic system validation;

    Abstract : One of the largest energy losses in an excavator is the compensation loss. In a hydraulic load sensing system where one pump supplies multiple actuators, these compensation losses are inevitable. READ MORE

  6. 25. Design of a radial-inflow microturbine for combined heat and power generation unit

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Salvador María Beltrán Martínez; [2021]
    Keywords : radial inflow turbine; turbomachinery; rotor; nozzle vanes; reaction; design; TurbAero; CAD; blade speed ratio; specific speed; efficiency; turbine exhaust; turbine; inlet; pressure drop; Euler equation; losses; blade loading plot; pressure side; suction side; Technology and Engineering;

    Abstract : This project aims to design a radial inflow microturbine that will be part of a system to generate both heat and electricity. Considering the specific power and the mass flow rates involved with the system, a radial inflow turbine was chosen. This type of turbine provides much larger power density in a single stage compared to the other types.. READ MORE
