  1. 1. Polarizability and Orientation Dynamics of Small Proteins

    University essay from Uppsala universitet/Materialteori

    Author : Ebba Koerfer; [2022]
    Keywords : Protein orientation; single-particle imaging; polarizability; orientation dynamics; rigid rotor model;

    Abstract : Proteins often carry an intrinsic electric dipole moment, which can interact with external electric fields and cause protein motion. Previous research has found that the orientation of small proteins in gas phase can be controlled in a static electric field. READ MORE

  3. 2. 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

  4. 3. Comparison of Achieved Fuel Savings on Ships by Different Wind Propulsion Systems Using a 3-DoF Resistance Model

    University essay from KTH/Marina system

    Author : Severi Sarsila; [2022]
    Keywords : ;

    Abstract : This thesis aims to determine how different wind propulsion systems should be sized in order to achieve comparable fuel savings. The selected wind propulsion systems for the comparison are Dynarig, rigid wing sail and rotor sail. To answer this question, a performance prediction program based on a 3 Degree of Freedom resistance model was developed. READ MORE

  5. 4. Performance Prediction Program for Wind-Assisted Cargo Ships

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Martina Reche Vilanova; [2020]
    Keywords : ;

    Abstract : Due to the accelerating need for decarbonization in the shipping sector, wind-assisted cargo shipsare able to play a key role in achieving the IMO 2050 targets on reducing the total annual GHGemissions from international shipping by at least 50%. The aim of this Master’s Thesis project is todevelop a Performance Prediction Program for wind-assisted cargo ships to contribute knowledgeon the performance of this technology. READ MORE

  6. 5. Modelling and Identification of a RUAV

    University essay from Linköpings universitet/Reglerteknik

    Author : Alaa Saeed; Mattias Mucherie; [2018]
    Keywords : ;

    Abstract : Modelling a linear mathematical model of a radio controlled (RC) helicopter in hover is the main goal of this thesis. The thesis introduces a general description about how RC-helicopters work and different phenomenons that effect the behaviour of a RC-helicopter. These phenomenons play an important role in the modelling part. READ MORE
