  1. 1. Predictive Modeling of Pipetting Dynamics. Multivariate Regression Analysis: PLS and ANN for Estimating Density and Volume from Pressure Recordings

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Lisa Linard Pedersen; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Thermo Fisher Scientific manufacture automatic pipetting instruments for diagnostic tests. These tests are sensitive to abnormalities and changes in e.g. volume or density could potentially lead to less precision or other issues in the pipetting work flow. LÄS MER

  3. 2. Magnetic field separation for current prediction in three-phase systems : Regression-based current prediction

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Sara Lenman; Sofia Blaad; [2023]
    Nyckelord :Alternating Current; Crosstalk Separation; Magnetic field sensors; Regression; Sensor technology; Three-phase system;

    Sammanfattning : Current controls the motion of a manipulator. The manipulators at ABB are powered by a three-phase alternating current system where shunt resistors are utilised to measure the current to the motors. Magnetic field sensors are instead investigated to eliminate issues with power losses, the number of components and the cost of the shunt resistors. LÄS MER

  4. 3. Exchanging 'Life' for Money? Overtime work culture and professional women's fertility intentions in China

    Master-uppsats, Lunds universitet/Graduate School

    Författare :Jinxuan Lu; [2023]
    Nyckelord :Fertility intention; Overtime work; PLS-SEM; Vignette experiment; Theory of Planned Behavior; Social Sciences;

    Sammanfattning : In the context of China’s concerning decline in fertility rates and the widespread normalization of the ‘996’ overtime culture, the connection between overtime work and fertility assumes considerable importance. This research is firmly grounded in the theoretical framework of the Theory of Planned Behavior (Ajzen, 1991), which investigates the complex relationship between overtime work and fertility intentions among working women of reproductive age in urban China.

  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. Examine the Impact of Attractiveness of Social Media Influencers on Douyin User Purchase Intentions: A Quantitative Study of Sportswear Industry

    Magister-uppsats, Lunds universitet/Företagsekonomiska institutionen

    Författare :Zehui Sun; Xiaoyuan Cheng; [2023]
    Nyckelord :Social media influencer; Influencer marketing; Source attractiveness; Consumer attitude; Purchase intention; Business and Economics;

    Sammanfattning : Thesis purpose: The objective is to understand the impact of social media influencers’ familiarity, likeability and similarity on the purchase intention of Douyin users, particularly in the sportswear industry. Methodology: This study has utilised a quantitative method based on a positivist philosophical position, and followed a deductive approach. LÄS MER
