  1. 6. Inversa problem för resistornätverk

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Emma Mattsson; Felicia Eriksson; [2021]
    Nyckelord :;

    Sammanfattning : I alla elektriska apparater finns det elektriska kretsar som behövs för att kunna utnyttja strömmens energi, som i sin tur gör att apparaten kan fungera. Antag att den elektriska kretsen, enbart består av resistorer, har en känd struktur men att resistorernas resistanser är okänd. LÄS MER

  3. 7. Regularization parameter selection methods for an inverse dispersion problem

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Anna Palmberger; [2021]
    Nyckelord :;

    Sammanfattning : There are many regularization parameter selection methods that can be used when solving inverse problems, but it is not clear which one is best suited for the inverse dispersion problem. The suitability of three different methods for solving the inverse dispersion problem are evaluated here in order to pick a suitable method for these kinds of problems in the future. LÄS MER

  4. 8. Bilinear Gaussian Radial Basis Function Networks for classification of repeated measurements

    Master-uppsats, Linköpings universitet/Matematisk statistik; Linköpings universitet/Tekniska fakulteten

    Författare :Andreas Sjödin Hällstrand; [2020]
    Nyckelord :Bilinear Regression; Classification; Supervised Learning; High Dimensional Statistics; Growth Curve Model; Regularization; Radial Basis;

    Sammanfattning : The Growth Curve Model is a bilinear statistical model which can be used to analyse several groups of repeated measurements. Normally the Growth Curve Model is defined in such a way that the permitted sampling frequency of the repeated measurement is limited by the number of observed individuals in the data set. LÄS MER

  5. 9. Parameter identification in a mathematical model of HIV infection with drug therapy

    Magister-uppsats, Institutionen för matematiska vetenskaper

    Författare :Martin Eriksson; [2017-12-12]
    Nyckelord :;

    Sammanfattning : Parameter identification problems are frequently occurring within biomedical applications. These problems are often ill-posed, and thus challenging to solve numerically. LÄS MER

  7. 10. Reconstruction in Computerized Tomography using Entropy Regularization

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Theoharis Charitidis; Martin Sjöberg; [2017]
    Nyckelord :;

    Sammanfattning : Inverse problems are a class of problems that often appear in science. They canbe thought of as calculating the cause that corresponds to measured data, andit is the opposite (i.e. inverse) of a direct problem, where data is calculated froma known source. LÄS MER
