  1. 1. Teacher characteristics and choicesand their effects on reading achievement: A comparision between Sweden and Quebec

    Master-uppsats, Göteborgs universitet/Institutionen för pedagogik och specialpedagogik

    Författare :Andrea Barber; [2024-01-12]
    Nyckelord :PIRLS 2011; reading achievement; SEM; cross-country comparison; teacher and classroom factors;

    Sammanfattning : Purpose. The purpose of this study is to compare teacher and classroom factors that are believed to affect students’ reading achievement scores at the fourth grade level by using PIRLS 2011 dataset. LÄS MER

  3. 2. 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

  4. 3. Evaluation of Physics Informed Neural Networks in engineering simple structural analysis problems

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Georgios Nentidis; [2023]
    Nyckelord :;

    Sammanfattning : Neural Networks have found many applications for a long time in Machine Learning in different disciplines, and have especially flourished in the last decade because of the ever-increasing processing power especially from GPUs. Because of their ability to operate as universal function approximators and model nonlinear processes, attempts have been made in recent years to be also used for modeling partial differential equation (PDE) solutions.

  5. 4. Att köra eller att inte köra : ett steg mot en acceptansmodell för självkörande fordon

    Kandidat-uppsats, Uppsala universitet/Institutionen för informatik och media

    Författare :Lana Ali; Emilia By; [2023]
    Nyckelord :Acceptans; initialt förtroende; kompatibilitet; självkörande bilar; Technology Acceptance Model; upplevd risk;

    Sammanfattning : Självkörande fordon har tillskrivits fördelar såsom reducering av trafikolyckor samt bränsleutsläpp. Samtidigt återfinns en påtaglig upplevd osäkerhet för tekniken hos potentiella användare. Syftet med denna studie var att vidareutveckla och testa en acceptansmodell för självkörande fordon. LÄS MER

  7. 5. Carabids as weed seed control agent : impact of soil cultivation on carabid weed seed regulation

    Master-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Ellen Dahlgren; [2023]
    Nyckelord :weed seed predation; weed seed bank regulation; weed seed predation strength; seed predation strength; carabid beetles; tillage; piecewise structural equation model;

    Sammanfattning : As weed seed predators, carabid beetles can regulate the weed seed bank within agricultural fields. Little is anyhow known about how weed seed bank regulation by carabids is affected by different tillage treatments with decreasing intensity, why this was here examined. LÄS MER
