  1. 1. Regularization Methods and High Dimensional Data: A Comparative Study Based on Frequentist and Bayesian Methods

    Kandidat-uppsats, Lunds universitet/Statistiska institutionen

    Författare :Markus Gerholm; Johan Sörstadius; [2024]
    Nyckelord :Linear regression; high dimensional data; regularization; Bayesian methods; Mathematics and Statistics;

    Sammanfattning : As the amount of high dimensional data becomes increasingly accessible and common, the need for reliable methods to combat problems such as overfitting and multicollinearity increases. Models need to be able to manage large data sets where predictor variables often outnumber the amount of observations. LÄS MER

  3. 2. Moderling Acoustic Transmission in Towed Array Sonars : Computations of the coupled acoustic and elastic wave equations

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Bill Claesson; [2023]
    Nyckelord :;

    Sammanfattning : This thesis presents a method of solving the Helmholtz equation coupled with the Navier-Cauchy equation over a cross section of a Towed Array Sonar (TAS) modeled as a simplified cylindrical shell. The purpose of solving these equations is to estimate the transfer function of the pressure between the outside boundary and a position inside the TAS. LÄS MER

  4. 3. Eulers polyederformel och Lakatos monsterhantering

    Kandidat-uppsats, Uppsala universitet/Matematiska institutionen

    Författare :Alice Danielsson; [2023]
    Nyckelord :Lakatos; Proofs and Refutations; Euler; Polyederformel; Bevis och Motbevis;

    Sammanfattning : In this essay the heuristic method of proofs and refutations, as pre- sented in the book Proofs and refutations by Imre Lakatos, is reviewed and discussed. Some background is given of heuristic methodology in contrast to the deductivist method and then Euler’s polyhedron for- mula is presented. LÄS MER

  5. 4. Data-driven Interpolation Methods Applied to Antenna System Responses : Implementation of and Benchmarking

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Lucas Åkerstedt; [2023]
    Nyckelord :Model Order Reduction; Loewner Framework; State-space Representation; Nevanlinna-Pick Interpolation; Vector Fitting; Cauchy interpolation; Antenna System Responses; Benchmarking; MoM; Data-driven; Interpolation; Modelordningsreducering; Loewner Ramverk; Tillståndsrepresentation; NevanlinnaPick Interpolering; Vector Fitting; Cauchy Interpolering; Antennsystemsvar; Prestandajämförelse; MoM; Datadriven; Interpolering;

    Sammanfattning : With the advances in the telecommunications industry, there is a need to solve the in-band full-duplex (IBFD) problem for antenna systems. One premise for solving the IBFD problem is to have strong isolation between transmitter and receiver antennas in an antenna system. LÄS MER

  7. 5. Quaternionic Analysis

    Kandidat-uppsats, Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Författare :Mitra Fathian Pourkondori; [2022]
    Nyckelord :Quaternion;

    Sammanfattning : In this thesis, we study Quaternionic Analysis, which is the most natural and close generalization of complex analysis. Quaternion Analysis conserves many of its important features by key reference A. Sudbery. LÄS MER
