  1. 1. Predicting True Sepsis and Culture-positive Sepsis in Intensive Care Unit with Machine Learning Techniques

    University essay from Lunds universitet/Matematisk statistik

    Author : Zeyuan Wu; [2024]
    Keywords : Machine Learning; Diagnosis of Sepsis; XGBoost; Logistic Regression; Mathematics and Statistics;

    Abstract : Sepsis, a serious medical condition often leading to patients requiring intensive care, has prompted numerous scientists to employ mathematical techniques to aid in its diagnosis. This thesis uses logistic regression and a machine learning technique, XGBoost, to predict true sepsis (as opposed to sepsis mimics) and culture-positive sepsis (among true sepsis) in critical care using blood test results, physiological measurements and other patient characteristics.

  2. 2. Using NeRF- and Mesh-Based Methods to Improve Visualisation of Point Clouds

    University essay from Lunds universitet/Matematik LTH

    Author : Vilma Ylvén; Oscar Montelin; [2024]
    Keywords : Technology and Engineering; Mathematics and Statistics;

    Abstract : In recent years, the field of generating synthetic images from novel view points has seen some major improvements. Most importantly with the publication of Neural Radiance Fields allowing for extremely detailed and accurate 3D novel views. READ MORE

  3. 3. Constructing Subalgebras of K[x] Using the Minimal Polynomial

    University essay from Lunds universitet/Matematik LTH

    Author : Marianne Ljunggren; [2023]
    Keywords : Algebra; Subalgebra; Polynomial Algebra; Minimal Polynomial; Mathematics and Statistics;

    Abstract : In this report we will be working with subalgebras A of finite codimension in K[x]. It is known that such subalgebras can be expressed using a set of linear conditions evaluated at a finite set of points called the spectrum elements of A. READ MORE

  4. 4. Error propagation in nuclear models

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Artis Mucenieks; [2023]
    Keywords : Physics and Astronomy;

    Abstract : In this thesis we perform error analysis of a nuclear model based on density-functional theory developed in Lund. The Lund model allows us to perform calculations of nuclear spectra more efficiently by constructing a simple effective Hamiltonian reproducing the quadrupole deformation and pairing interaction strength parameters of a spherical Hartree-Fock reference functional.

  5. 5. Self-supervised monocular depth estimation for dynamic scenes

    University essay from Lunds universitet/Matematik LTH

    Author : Jonathan Lindberg; [2021]
    Keywords : Mathematics and Statistics;

    Abstract : Estimating depth from an image is an ill-fitted problem, since we project a three-dimensional space to a two-dimensional image. However, human can estimate a plausible depth from only a single eye and often are we relaying on this for quick estimation of moving objects. READ MORE
