  1. 16. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis

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

    Author : Simon Pääjärvi; [2022]
    Keywords : Rotordynamics; Applied Mechanics; Dynamics; Rotor; Finite Element Analysis; Hydropower; Solid Mechanics; Energy Production;

    Abstract : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. READ MORE

  3. 17. Importance Sampling in Wireless Communication Systems with Ultra-Low Error Rates

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Bharat Maheshwari; Yewen Zhou; [2022]
    Keywords : error region; Monte Carlo; importance sampling; rejection sampling; Kullback-Leibler divergence.; Technology and Engineering;

    Abstract : Simulation mimics the behaviour of real world processes or the system over time. It helps us to understand the impact of modification and the effect of introducing various interventions to a system. READ MORE

  4. 18. Controlling latency for batteryless sensors through environment control

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : David Håkansson; [2022]
    Keywords : ;

    Abstract : In this study we look at reducing the intermittency of a system harvesting Radio Frequency (RF)signals and/or harvesting photons through a solar cell. This is done through the usage of a smart bulb or a RF generator. Which by increasing the amount of photons or RF signals in the environment, increases the energy in the environment. READ MORE

  5. 19. Design and Development of a Data Acquisition and Communication System for Point Absorber Tracking

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Balakrishnan Kannan; [2021]
    Keywords : Data Acquisition System; Raspberry Pi; Controller; Processor; Wave buoy; Lysekil; wave energy; measurements; IMU; GPS; Strain gauge; force; Solar energy; Battery; communication; 4G; internet; Remote tracking; Shell; Python;

    Abstract : The recent trend in generating energy from the waves has led to several advancements in the methods and the various research is conducted across the world, to study the behaviour of point absorbers on the waves. The point absorbers such as wave buoys are designed to move according to the waves and the generator that is mechanically coupled with the buoys, generate electricity. READ MORE

  6. 20. Tuning of Power System Stabilizers to Damp Out Power Oscillations

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Joel Viil; Marcus Seisay; [2021]
    Keywords : Power System Stabilizer; Critical Generator; Small Signal Instability; Terminal Voltage; Field Voltage; Frequency;

    Abstract : With the rise of global sustainability energy initiatives,the implementation of renewable energy sources infuture electrical grids is increasing. Many of the renewableenergy sources are however intermittent, meaning they providevarying levels of power. READ MORE
