  1. 1. Hur påverkas elevers förståelse för multiplikation av areamodeller som representation? En designstudie i en grekisk grundskola med elever i Åk 2, där undervisningsprocessen fokuserar multiplikativt tänkande samt kommutativa lagen för multiplikation

    Master-uppsats, Göteborgs universitet/Institutionen för didaktik och pedagogisk profession

    Författare :Antelina Sema; [2024-03-04]
    Nyckelord :Multiplikativt tänkande; Areamodell för multiplikation; Kommutativa lagen; Proportionalitet;

    Sammanfattning : This design study explores the use of the area model as a representation of multiplication, providing opportunities for second school grade pupils to develop an understanding of multiplication and build multiplicative thinking. Furthermore, the study aims to give pupils the opportunity to discover the commutative law of multiplication with the help of the area model. LÄS MER

  3. 2. Predicting True Sepsis and Culture-positive Sepsis in Intensive Care Unit with Machine Learning Techniques

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Zeyuan Wu; [2024]
    Nyckelord :Machine Learning; Diagnosis of Sepsis; XGBoost; Logistic Regression; Mathematics and Statistics;

    Sammanfattning : Sepsis, a serious medical condition often leading to patients requiring intensive care, has prompted numerous scientists to employ mathematical techniques to aid in its diagnosis. This thesis uses logistic regression and a machine learning technique, XGBoost, to predict true sepsis (as opposed to sepsis mimics) and culture-positive sepsis (among true sepsis) in critical care using blood test results, physiological measurements and other patient characteristics.

  4. 3. Buildings in the Digital Era : An Explorative Study of Digital Twins in the Built Environment

    Master-uppsats, KTH/Industriell ekonomi och organisation (Inst.)

    Författare :Siw Kristine Kästel; Joanna Wallén; [2024]
    Nyckelord :Digital Twin DT ; Arcitecture; Engineering and Construction AEC industry; Digitization; Building Information Modeling BIM ; Facility Management FM ; Operation Management O M ; Digital Tvilling; Fastighetsbranschen; Fastighetsförvaltning; Byggnadsinformationsmodeller BIM ;

    Sammanfattning : In recent years, digital twins (DT) have gained traction in enhancing operation and maintenance procedures across various industrial sectors, such as manufacturing, energy, and aerospace. Yet their utilization remains more limited in the built environment. LÄS MER

  5. 4. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Grigore-Leon Ratiu; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. LÄS MER

  7. 5. Assessing water balance and yields in Malawian cropping systems : maize soybean and maize Gliricidia systems resilience against climate change

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Danila Valeriano; [2024]
    Nyckelord :crop modelling; APSIM; Malawi; maize; soybean; Gliricidia; agroforestry; legume intercropping; climate predictions; climate adaptation; SDSM;

    Sammanfattning : In Malawi, maize monocultures are increasingly susceptible to extreme weather patterns, causing considerable yield reduction and heightened food insecurity for smallholder farmers dependent on rainfed subsistence agriculture. Diversifying cropping systems is crucial for ensuring yield resilience. LÄS MER
