  1. 1. Randomized Diagonal Estimation

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Niclas Joshua Popp; [2023]
    Nyckelord :Diagonal estimation; randomized numerical linear algebra; low-rank approximation; matrix functions; Diagonalestimering; randomiserad numerisk linjär algebra; lågrankad approximation; matrisfunktioner;

    Sammanfattning : Implicit diagonal estimation is a long-standing problem that is concerned with approximating the diagonal of a matrix that can only be accessed through matrix-vector products. It is of interest in various fields of application, such as network science, material science and machine learning. LÄS MER

  5. 4. En praktisk process för totalkostnadsanalys inom inköp : En studie om totalkostnadsanalys baserat på artikeluppdelning inom lågvolymstillverkande företag

    Kandidat-uppsats, Jönköping University/JTH, Logistik och verksamhetsledning

    Författare :Marcus Schwartz; Frida Wygler; [2023]
    Nyckelord :Totalkostnadsanalys TCA ; total ägandekostnad TCO ; totalkostnadsanalysprocess; inköp; lågvolymstillverkande företag; artikeluppdelning; category management; Kraljics matris;

    Sammanfattning : Syfte: I den komplexa miljö som inköp inom lågvolymstillverkande företag befinner sig i ställs krav på kostnadsreducering. Ofta är fokus på inköpspriset medan flertalet osynliga kostnader, som ofta är större, är dolda under vattenytan. LÄS MER

  7. 5. AI Based Methods for Matrix Multiplication in High Resolution Simulations of Radio Access Networks

    Master-uppsats, KTH/Matematisk statistik

    Författare :Marcus Johnson; Herman Forslund; [2023]
    Nyckelord :Product-Quantization; MADDNESS; Radio Access Networks; Channel Estimation; MIMO; Approximate Matrix Multiplication; Pruduktkvantisering; MADDNESS; RAN; MIMO; Approximativa matrismultiplikation;

    Sammanfattning : The increasing demand for mobile data has placed significant strain on radio access networks (RANs), leading to a continuous need for increased network capacity. In keeping with that, a significant advancement in modern RANs is the ability to utilize several receivers and transmitters, to allow for beamforming. LÄS MER
