  1. 1. Do viscous flows slip?

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Björn Sjösvärd; [2023-12-21]
    Nyckelord :Mathematics; partial differential equations; multivectors; Hodge de-compositions; the Stokes equation; Hodge boun;

    Sammanfattning : In this thesis, the Stokes equation is discussed and solved under different boundary conditions. The Stokes equation governs the flow of viscous liquids, for example honey or syrup. The first chapters in the thesis provides an introduction to multivector algebra and analysis, with the aim of presenting the concept of Hodge decompositions. LÄS MER

  3. 2. Impact of Frame Stiffness on Tribological Behaviour of Sliding Interfaces

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

    Författare :Nisha Singh; [2023]
    Nyckelord :coefficient of friction; friction-vibration interaction; stiffness; tribometer; vibrations; friktionskoefficient; friktion-vibrationsinteraktion; styvhet; tribometer; vibrationer;

    Sammanfattning : Friction and wear have been concerns to industrialists, scientists and environmentalist for several decades. Many robust models have been developed to address friction and wear and their dependency on various parameters. Numerous experiments have been conducted in the past to model friction and wear.

  4. 3. 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

  5. 4. Monetary Policy with Credit Market Frictions

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Mambuna Njie; [2023]
    Nyckelord :Monetary policy; Investments; Credit frictions; Collateral constraints;

    Sammanfattning : I study the role of collateral as a source of financial friction in the transmission of monetary policy towards firms' investments. First, I use a panel of Swedish firms to estimate the heterogeneity in firm investment responses to monetary policy shocks conditional on collateral. LÄS MER

  7. 5. 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
