  1. 21. Quantum thermodynamics explorations with a Hubbard-Holstein dimer

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Emil Adam Jonatan Östberg; [2021]
    Nyckelord :QTD Quantum Thermodynamics Hubbard-Holstein Hubbard Holstein dimer Lanczos Suzuki-Trotter ST Exact diagonalization ED Hysteresis Path dependence Battery Mott-insulator; Physics and Astronomy;

    Sammanfattning : The goal of this project is to characterize the quantum thermodynamics of a Hubbard-Holstein dimer. We explore how the standard formalism of quantum thermodynamics behaves in the context many-body physics. LÄS MER

  2. 22. Test Equipment for Physical Testing of Vibration Isolator

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :ADAM ALVETEG; MARKUS JOHANSSON; [2021]
    Nyckelord :Test rig; vibration isolator; hysteresis; Testrigg; vibrationsisolator; hysteres;

    Sammanfattning : Vibrations is a phenomenon that can cause problems to systems if not dealt with. In heavy duty trucks, vibrations are mainly caused by uneven roads and from the combustion engine. Vibrations can damage components, reduce their service life and cause discomfort for the driver.

  3. 23. Closed-Loop Control of a 3D Printed Soft Actuator with Soft Position Sensors

    Master-uppsats, KTH/Mekatronik

    Författare :Jakob Jansson; Mikael Sjöberg; [2021]
    Nyckelord :Soft Actuators; 3D Printing; Closed-Loop Control; Strain Sensor; Soft Gripper; Mjuka Ställdon; 3D-Skrivning; Återkopplad Kontroll; Töjningssensor; Mjukt Gripdon;

    Sammanfattning : This thesis performs closed-loop control of a 3D printed soft bending actuator with feedback from a 3D printed strain sensor. This process utilizes the Finite Element Method (FEM) to design a bellow type pneumatic bending actuator that can handle pressures up to 4 bar. LÄS MER

  4. 24. FEM Simulation Study of Iron Losses for a Linear Generator

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Pramod Hassan Kantharaj; [2021]
    Nyckelord :;

    Sammanfattning : Over the past few years, electricity generation from renewable resources has increased. Power generation from the ocean waves is also one among them. The technology consists of many subsystems. Generators are considered the heart of the entire subsystem or technology. LÄS MER

  5. 25. A 3D Sliding Bearing Finite Element Based on The Bouc-Wen Hysteretic Model : Mathematical modelling and numerical implementation

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Sicong Wei; [2020]
    Nyckelord :high-speed railway; nonlinear dynamics; bridge bearings; friction; hysteresis; secondary development; damping;

    Sammanfattning : Bridge bearing is an essential component with the function of connecting the superstructure and substructure of the bridge, transmitting load and providing movability to the superstructure. Under dynamic conditions, the internal friction of bridge bearing dissipates the vibration energy and therefore reduces the dynamic response of the bridge. LÄS MER
