  1. 1. Deep Learning for the prediction of RASER-MRI profiles

    University essay from Linköpings universitet/Medie- och Informationsteknik

    Author : Filip Arvidsson; Jonas Bertilson; [2023]
    Keywords : MRI; NMR; AI; Deep Learning; RASER-MRI; Media Technology; KIT; LIU; CNN; Autoencoder; Djupinlärning; Medieteknik; Magnetröntgen;

    Abstract : Magnetic resonance imaging (MRI) is a critical diagnostic tool in medical practice, enabling non-invasive visualization of anatomy and physiological processes. Nonetheless, MRI has inherent spatial resolution limitations, which may limit its diagnostic capabilities. READ MORE

  3. 2. Dynamic Covariance Modelling Using Generalised Wishart Processes

    University essay from Lunds universitet/Matematisk statistik

    Author : Fredrik Nilsson; [2023]
    Keywords : Covariance matrix; generalised Wishart process; Bayesian inference; Markov chain Monte Carlo; Hamiltonian Monte Carlo; Mathematics and Statistics;

    Abstract : Modern portfolio theory was pioneered by Markowitz who formulated the mean-variance problem, without which any discussion on quantitative approaches to portfolio selection would be incomplete. The framework boils down to finding the expected return $\mu$ and covariance $\Sigma$, after which the solution is proportional to $\Sigma^{-1}\mu$. READ MORE

  4. 3. Processing of ERT data from Stabilised Columns

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Mårten Petersson; [2023]
    Keywords : inversion; ERT; quality control; jet grouting; aarhusinv; Technology and Engineering;

    Abstract : Modern construction sites are associated with high demands on suitable soil conditions, resulting in geotechnical challenges that can be solved using soil stabilisation techniques. The reliability of these techniques is tested using different quality assurance methods. READ MORE

  5. 4. Optimizing the Cash Reserve in a Portfolio of US Life Insurance Policies

    University essay from Linköpings universitet/Produktionsekonomi

    Author : Alva Happe; Wassim Seifeddine; [2022]
    Keywords : portfolio optimization; risk management; monte carlo; value at risk; life settlements; longevity risk; cash reserve; closed-end fund;

    Abstract : Hoarding a too large cash reserve is often unfavourable due to lost investment opportunities. Similarly, an insufficient cash reserve can be detrimental, as one might fail to meet payment obligations. Finding the optimal balance is nothing that is done in the blink of an eye, particularly when the underlying variable is stochastic, e.g. READ MORE

  6. 5. Application of ERT for Quality Assurance in Jet Grouting Columns; A development of an alternative quality control

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Edvin Nilsagård; Rebecka Knutsson; [2022]
    Keywords : ert; jet grouting; quality control; pygimli; res2dinv; resistivity; Technology and Engineering;

    Abstract : With the increased urbanization major cities are facing, expansion of larger facilities and households are inevitable. Expansion means larger areas of the surface needs to be used where the risk of varying subsurface soil properties increases with larger surface areas. READ MORE
