  4. 8. Automation of carbonyl index calculations for fast evaluation of microplastics degradation

    University essay from KTH/Fysik

    Author : Maja Walfridson; Emma Kuttainen Thyni; [2022]
    Keywords : FTIR; Carbonyl index; Degradation of microplastics; Microplastics; Automation;

    Abstract : The broad use of plastics has resulted in the increase in both production and consequent plastic pollution in the environment. Microplastics, defined as particles < 5 mm, is of special interest because of its wide existence in environment and potential hazards to our ecosystem. READ MORE

  5. 9. 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
