  1. 6. Neural Networks for Material Decomposition in Photon-Counting Spectral CT

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Hugo Charrier; [2022]
    Keywords : PCCT; X-ray; scanner; photon counting; AI; neural networks;

    Abstract : Photon counting computed tomography scanners constitute a major improvement of the field of computed tomography, opening various prospective and enabling the decomposition of computed tomography images into different materials. The material decomposition algorithm, mapping photon counts to material pathlengths, relies on a forward model with Poisson statistics. READ MORE

  3. 7. Future Electricity Consumption and Wind Power Production in Sweden - Effects of Climate Change

    University essay from Lunds universitet/Matematisk statistik

    Author : Ingrid Torstensson; [2021]
    Keywords : Electricity system; Bias Correction; Quantile Mapping; Climate Model; Emission scenarios; Mathematics and Statistics;

    Abstract : To maintain stability in the Swedish electricity grid, Svenska kraftnät must be able to predict future electricity production and consumption. Earlier this have been done by using historical data. READ MORE

  4. 8. Ground validation and bias correction of GPM-IMERG V6 satellite precipitation product over Sweden

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Mojtaba Moravej; [2020]
    Keywords : satellite precipitation product; bias correction; GPM-IMERG; Monte Carlo; evaluation; rain; Earth and Environmental Sciences;

    Abstract : This study attempts to assess and correct the performance of Integrated Multi-satellite Retrievals for Global Precipitation Measurement (GPM-IMERG) final run daily precipitation product across Sweden. The performance of GPM-IMERG version 6 final run was evaluated against 677 rain gauges in a period from 12 March 2014 to 31 May 2019. READ MORE

  5. 9. Evaluation of X-band Weather Radar Data in Urban Hydrology

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Alva Kalm; Camilla Hedell; [2019]
    Keywords : Urban hydrology; X-band radar; Bias correction; Error analysis; Neural network; Scania.; Technology and Engineering;

    Abstract : Throughout history it has always been crucial to accurately measure, track, and predict precipitation. This has been done using various methods with varying degrees of precision. As the world evolves and as urban areas expand, it has become more apparent that there is a need for a more efficient way to observe and record precipitation. READ MORE

  6. 10. Determinants of Non-Performing Loans: A Panel Data Empirical Analysis for South European Countries

    University essay from Lunds universitet/Nationalekonomiska institutionen

    Author : Tom Ghorbani; Viktor Jakobsson; [2019]
    Keywords : Non-performing loans; Bank-specific determinants; Macroeconomic determinants; Interactive Effects; Cross-sectional dependence; Business and Economics;

    Abstract : The paper analyzes the determinants of non-performing loans in 19 European banks in Portugal, Italy, Greece and Spain based on quarterly data between 2006–2018. We implement a panel data model with interactive effects, which accounts for unobserved heterogeneity and cross-sectional dependence. READ MORE
