  1. 1. Establishment of a deep learning algorithm for dosimetry of radiopharmaceuticals

    Master-uppsats,

    Författare :Dennis Lipnicevic; [2022-01-13]
    Nyckelord :Medical physics; automated segmentation; dosimetry; kidney; nuclear medicine dosimetry; deep learning; convolutional neural network;

    Sammanfattning : Purpose: The aim of this study was to introduce a volumetric convolutional neural network for segmentation of the kidneys in SPECT images and to apply it in the dosimetry of radiopharmaceuticals of this organ, in order to decrease segmentation time and to standardize the segmentation of the kidneys. Method: Three networks were trained using two network architectures and a total of 216 retrospectively collected images from patients that underwent imaging procedures at Sahlgrenska University Hospital between 2009 and 2018.

  2. 2. Economic Empowerment: Protection or Risk? : - A quantitative study on economic empowerment and intimate partner violence

    Kandidat-uppsats, Uppsala universitet/Statsvetenskapliga institutionen

    Författare :Signe Wiktorsson; [2022]
    Nyckelord :violence against women; intimate partner violence; IPV; intimate partner violence against women; IPVAW; economic empowerment; marital dependency theory; relative resource theory;

    Sammanfattning : Violence against women is an issue faced by women all over the world. Violence conducted by a partner or husband is the most common form of violence that women are targeted by. Intimate partner violence against women (IPVAW) is internationally recognized as a human rights violation as well as a major global health issue. LÄS MER

  3. 3. Early Detection and Differentiation of Circulatory Shock in the Intensive Care Unit using Machine Learning

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Therese Lindberg; [2022]
    Nyckelord :machine learning; prediction; circulatory shock; intensive care unit; ICU;

    Sammanfattning : In the intensive care unit, patients with crucial, life-threatening conditions are admitted and need constant monitoring. Here, the need for a quick and efficient decision support tool is the greatest. LÄS MER

  4. 4. Äldres tankar och reflektioner att självständigt genomföra 30 second chair stand test i hemmiljö - En intervjustudie

    Kandidat-uppsats, Uppsala universitet/Åsenlöf: Fysioterapi

    Författare :Petter Wik; Joakim Skärlén; [2022]
    Nyckelord :30CST; Hometest; Balance; Elderly; Qualitative analysis;

    Sammanfattning : Bakgrund: Fall är en bidragande anledning till fallskador som kräver sjukhusvistelse för den äldre populationen. Det finns i dagsläget flera olika balanstest som genomförs i klinik, däremot finns det inget som är undersökt för att tillämpas självständigt i hemmiljö. LÄS MER

  5. 5. Insurance Fraud Detection using Unsupervised Sequential Anomaly Detection

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Anton Hansson; Hugo Cedervall; [2022]
    Nyckelord :Insurance Fraud Detection; Anomaly Detection; Long Short-Term Memory Networks LSTM ; Unsupervised Learning; Autoencoder AE ; Variational Autoencoder VAE ; Interpretable Machine Learning; Feature Engineering; Feature Selection; Feature Importance;

    Sammanfattning : Fraud is a common crime within the insurance industry, and insurance companies want to quickly identify fraudulent claimants as they often result in higher premiums for honest customers. Due to the digital transformation where the sheer volume and complexity of available data has grown, manual fraud detection is no longer suitable. LÄS MER
