  4. 3. Diffusion-Based MR Methods for Measuring Water Exchange

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Shan Cai; [2022]
    Nyckelord :diffusion MRI; water exchange rate; membrane permeability; double diffusion encoding; DDE;

    Sammanfattning : Measuring transmembrane water exchange can provide potential biomarkers for tumors and brain disorders. Diffusion Magnetic Resonance Imaging (dMRI) is a well-established tool that can non-invasively measure water exchange across cell membranes. Diffusion Exchange Spectroscopy (DEXSY) is one of the dMRI-based frameworks used to estimate exchange. LÄS MER

  5. 4. Evaluating performance of homomorphic encryption applied on delta encoding

    Master-uppsats, Linköpings universitet/Databas och informationsteknik

    Författare :János Richard Dani; [2022]
    Nyckelord :homomorphic encryption; delta encoding; performance test;

    Sammanfattning : Homomorphic encryption is an encryption scheme that allows for simple operations on encrypted data. These operations are mainly boolean circuits combined into more complexarithmetic operations, rotations, and others. Homomorphic encryption was first implemented in 2009, and in the following decade, many different versions emerged. LÄS MER
