  1. 1. Preoperative prediction of sentinel nodal status using mammography images

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Malin Hjärtström; Maren Høibø; [2021]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Breast cancer is the most common cancer among women in Sweden, accounting for approximately 30 % of the cancer cases. The overall prognosis is good, but worsens if the cancer metastasizes from the primary tumor. LÄS MER

  2. 2. Scenario Dose Calculation for Robust Optimization in Proton Therapy Treatment Planning

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Johan Sundström; [2021]
    Nyckelord :cancer; radiation therapy; proton therapy; treatment planning; robust optimization; dose calculation algorithms; scenarios; patient setup; range error; organ motion; pencil beam scanning; computational efficiency; range-corrected dose-mapping; Mathematics and Statistics;

    Sammanfattning : Robust optimization plays a vital role in proton therapy treatment planning. A monoenergetic beam of protons has a finite range and delivers most of its dose at some specific depth in the patient. This allows the design of treatments that mainly damage the tumor and not any surrounding tissue. LÄS MER

  3. 3. Classification of EEG Data Using Convolutional Neural Networks and the Scaled Reassigned Spectrogram

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Karin Pagels; [2021]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : Electroencephalography (EEG) is a medical technique for measuring brain activity through several channels connected to the scalp. Interpreting EEG data is a difficult problem because of the large amount of noise contained in the data. LÄS MER

  4. 4. Cycltomoic Fields and Fermat's Last Theorem

    Kandidat-uppsats, Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Författare :Samuel Runyeon Odeberg; [2021]
    Nyckelord :pure mathematics; number theory; algebra; algebraic number theory; cyclotomic fields; cyclotomic rings; cycltomic integers; Fermat s last theorem; Mathematics and Statistics;

    Sammanfattning : Number theory is in a sense among the oldest disciplines of mathematics. A running theme is that many number theoretic problems are very easy to state and understand. However, actually solving these problems often requires much work or some very clever trick. LÄS MER

  5. 5. Hierarchical Clustering To Improve Portfolio Tail Risk Characteristics

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Adam Eidenvall; [2021]
    Nyckelord :Hierarchical Clustering; Asset Allocation; Portfolio Construction; Graph Theory; Machine Learning; Risk Parity; Regime Shift; Bootstrapping; Walk Forward; Mathematics and Statistics;

    Sammanfattning : Many agree that estimating portfolio risks has better estimation possibilities, than estimations on returns. Therefore investors attempts to construct better, more efficient riskmanaged portfolios by diversifying portfolios through factors rather than traditional asset classes. LÄS MER
