  1. 1. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Nipon Roy; [2023]
    Nyckelord :Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Sammanfattning : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. LÄS MER

  3. 2. Exploring time-extended complexity measures in magnetic systems

    L3-uppsats, Uppsala universitet/Materialteori

    Författare :Jannes van Poppelen; [2023]
    Nyckelord :;

    Sammanfattning : Complexity, a fundamental concept in physics, encompasses phenomena spanning atomic to cosmic scales. The natural emergence of complexity can be explained by self-organized criticality. In this work, two complexity measures in magnetic systems are explored. LÄS MER

  4. 3. Development of Friction/Blended Braking Capability for an Electric Driveline Model for Multi-Scale Road-Cargo Simulations

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Fangge Wu; [2023]
    Nyckelord :System Engineering; Matlab Simulink Simulation; Driveline Model Building; ABS; Friction and blended braking capabilities 4; Systems Engineering; Matlab Simulink-simulering; Driveline Model Building; ABS; friktion och mixade bromsfunktioner 6;

    Sammanfattning : This thesis focuses on the critical development of friction and blended braking capabilities for an electric driveline model intended for multiscale road-cargo simulations. In the rapidly evolving landscape of transportation, electric driveline technology has emerged as a key player in achieving sustainability and efficiency goals. LÄS MER

  5. 4. Improved Statistical Methods for Elliptic Stochastic Homogenization Problems : Application of Multi Level- and Multi Index Monte Carlo on Elliptic Stochastic Homogenization Problems

    Kandidat-uppsats, Uppsala universitet/Tillämpad beräkningsvetenskap

    Författare :Khalil Daloul; [2023]
    Nyckelord :Homogenization; Multilevel Monte Carlo; Multi-Index Monte Carlo; Monte Carlo; Multiscale methods;

    Sammanfattning : In numerical multiscale methods, one relies on a coupling between macroscopic model and a microscopic model. The macroscopic model does not include the microscopic properties that the microscopic model offers and that are vital for the desired solution. LÄS MER

  7. 5. Upscaling agroecology in Sweden : a participatory-backcasting approach to investigate top-down measures for promoting an agroecological transition of the Swedish agricultural system

    Master-uppsats, SLU/Dept. of People and Society

    Författare :Pablo Ratti; [2023]
    Nyckelord :Agroecology; transition; top-down; scenario; participatory policies;

    Sammanfattning : Alongside its important contribution to the increase of yields, industrial agriculture has also generated environmental, social and economical negative side effects. Moreover, the forecasted growth of the world’s population puts more pressure for solutions on how to increase food supply while reducing the negative effects of the current agricultural system.
