  1. 1. Framtagning av principkonstruktion för reglering av luftflöden inom ventilation

    M1-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Författare :Joakim Grönberg; Fredrik Hansson; [2023]
    Nyckelord :Ventilation; CFD; Exhaust hood; Ventilation; CFD; Avluftshuvar;

    Sammanfattning : Takmonterade avluftshuvar kan ha ett krav att kastlängden av luftflödet ska överstiga en minimal höjd över takytan. Moderna ventilationssystem av typen VAV (Variable Air Volume) kan anpassa luftflödet till olika rum beroende på antalet personer och mätvärden på luftkvalitet i rummen, vilket kan leda till ett lägre luftflöde under nätter och helger.

  3. 2. Syntetiskt pärlemor : Producerat via in situ-kristallisation

    Master-uppsats,

    Författare :Pontus Blomberg; [2023]
    Nyckelord :Biomineralisation; Aragonite; Calcium; Carbonate; CaCO3; CNC;

    Sammanfattning : This thesis describes a sequence of experiments which have been performed with the intention to produce synthetic nacre. Synthetic nacre is a biomimetic material based on nacre, a material which can be found in mollusc shells. Nacre is a nanocomposite which has improved mechanical properties compared to the principal component aragonite (95% wt%). LÄS MER

  4. 3. Clustering and classification of prepaid mortgages

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Jakob Atli Thorsteinsson; [2023]
    Nyckelord :Clustering; Classification; Klustring; Klassificering;

    Sammanfattning : This thesis aims to cluster and classify mortgages issued by a financial institution. The aim is to apply machine learning techniques on historical data in order to discover a possible structure and predictability in prepaid mortgages. LÄS MER

  5. 4. Public Domain Intelligence Tests: Psychometric properties of the Cog15 and ICAR16 cognitive ability scales

    Master-uppsats, Lunds universitet/Institutionen för psykologi

    Författare :Dagný Kristjánsdóttir; Aya Zaiter; [2023]
    Nyckelord :general intelligence; intelligence testing; public domain; CFA; PCA; Social Sciences;

    Sammanfattning : The current paper aims to explore the psychometric properties of two public domain cognitive ability scales, Cog15 and ICAR16, and investigate how well they each capture the g-factor in a Swedish sample (N = 428). The motivation for choosing these aims is that public domain, free, and easily accessible intelligence tests are needed for measuring the g-factor. LÄS MER

  7. 5. Environmental Management for System Engineering Projects : A Case Study on How to Bridge the Gap between Ambition and Action

    Master-uppsats,

    Författare :Lisa Rylander; [2023]
    Nyckelord :Sustainability; Environmental Management; System Engineering; Science-Based Targets; Carbon Footprint Analysis;

    Sammanfattning : This thesis focuses on addressing the challenge of managing the climate impact of system engineering projects within a large global industrial company. The research design is a case study within the selected company, and it integrates qualitative and quantitative methodologies to provide a holistic understanding of environmental challenges. LÄS MER
