  1. 1. Elevers uppfattning om likhetstecknet i matematik : En kvalitativ studie med kvantitativa drag

    Uppsats för yrkesexamina på avancerad nivå, Stockholms universitet/Institutionen för ämnesdidaktik

    Författare :Åkerberg Therese; [2022]
    Nyckelord :Likhetstecken; matematisk likhet; uppfattning; operationell aspekt; relationell aspekt;

    Sammanfattning : Syftet med studien var att bidra till en djupare förståelse för de uppfattningar elever i årskurs 1-3 har om likhetstecknet i matematik. För att behandla studiens syfte och frågeställning genomfördes datainsamlingen genom två olika metoder, vilka bestod av ett skriftligt test samt semistrukturerade intervjuer. LÄS MER

  3. 2. Classification in Functional Data Analysis : Applications on Motion Data

    Master-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistik

    Nyckelord :Classification; Functional Data Analysis; FDA; motion data; ligament injury;

    Sammanfattning : Anterior cruciate knee ligament injuries are common and well known, especially amongst athletes.These injuries often require surgeries and long rehabilitation programs, and can lead to functionloss and re-injuries (Marshall et al., 1977). LÄS MER

  4. 3. Product Similarity Matching for Food Retail using Machine Learning

    Master-uppsats, KTH/Matematisk statistik

    Författare :Hanna Kerek; [2020]
    Nyckelord :Product matching; Machine Learning; Random Forest; Logistic Regression; Support Vector Machines; Produktmatchning; maskininlärning; Random Forest; logistisk regression; Support Vector Machines;

    Sammanfattning : Product similarity matching for food retail is studied in this thesis. The goal is to find products that are similar but not necessarily of the same brand which can be used as a replacement product for a product that is out of stock or does not exist in a specific store.

  5. 4. The anti-amyloidogenic chaperone DNAJB6 and its interaction with other chaperones

    Kandidat-uppsats, Lunds universitet/Matematisk statistik; Lunds universitet/Kemiska institutionen

    Författare :Gemma Nilsson; [2020]
    Nyckelord :chaperones; DNAJB6; Hsc70; Hsp110; ATP-hydrolysis; Ab42; polyQ; biochemistry; biokemi; Chemistry;

    Sammanfattning : In order to maintain proteins’ functionality their native folding state must be preserved. Chaperones fold other proteins and DNAJ-chaperones may collaborate with Hsc70 chaperones to prevent aggregation of aggregation-prone peptides such as polyQ and Aβ42, which form fibrils in currently incurable diseases as Huntington’s and Alzheimer’s, respectively.

  7. 5. A study on the application of machine learning algorithms in stochastic optimal control

    Master-uppsats, KTH/Matematisk statistik

    Författare :Xin Huang; [2019]
    Nyckelord :;

    Sammanfattning : By observing a similarity between the goal of stochastic optimal control to minimize an expected cost functional and the aim of machine learning to minimize an expected loss function, a method of applying machine learning algorithm to approximate the optimal control function is established and implemented via neural approximation. Based on a discretization framework, a recursive formula for the gradient of the approximated cost functional on the parameters of neural network is derived. LÄS MER
