  1. 11. Measurement of the snow accumulation in Antarctica with a neutrino radio detector and extension to the measurement of the index-of-refraction profile

    University essay from Uppsala universitet/Högenergifysik

    Author : Jakob Beise; [2021]
    Keywords : Askaryan; UHE neutrinos; in-ice radio detection; in-situ detector calibration; deep learning; radio neutrino detector; ARIANNA;

    Abstract : High-energy neutrino physics offers a unique way to investigate the most violent phenomena in our universe. The detection of energies above E > 1017 eV is most efficient using the Askaryan effect, where a neutrino-induced particle shower produces coherent radio emission that is detectable with radio antennas.

  3. 12. Similarity models for atlas-based segmentation of whole-body MRI volumes

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Elin Axberg; Ida Klerstad; [2020]
    Keywords : Atlas-based segmentation; image registration; image similarity measures;

    Abstract : In order to analyse body composition of MRI (Magnetic Resonance Imaging) volumes, atlas-based segmentation is often used to retrieve information from specific organs or anatomical regions. The method behind this technique is to use an already segmented image volume, an atlas, to segment a target image volume by registering the volumes to each other. READ MORE

  4. 13. Estimation methods for Asian Quanto Basket options

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : David Adolfsson; Tom Claesson; [2019]
    Keywords : Monte Carlo simulation; Estimation; Option; Taylor expansion; Sensitivities; Price interpolation; Grid;

    Abstract : All financial institutions that provide options to counterparties will in most cases get involved withMonte Carlo simulations. Options with a payoff function that depends on asset’s value at differenttime points over its lifespan are so called path dependent options. READ MORE

  5. 14. Discussions on Dai-Freed Anomalies

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Huaiyu Li; [2019]
    Keywords : Anomaly; Quantum Fields Theory; Dai-Freed Theorem; Topology;

    Abstract : In both field theories of high energy physics and field theories of condensed matter theories anomalies have been imposing constraints and bringing up new theories. While the perturbational and local anomalies from triangle diagrams are well-developed, we follow and review two works leading to non-perturbational global anomalies both related with Atiyah-Patogi-Sieger (APS) index theorem.

  6. 15. Ray Tracing and Spectral Modelling of Excited Hydroxyl Radiation from Cryogenic Flames in Rocket Combustion Chambers

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Jaka Perovšek; [2018]
    Keywords : spectral modelling; excited hydroxyl radiation; OH* radiation; ray tracing; spectroscopy; rocket combustion chambers; rocket engines; hydrogen-oxygen combustion; combustion instabilities;

    Abstract : A visualisation procedure was developed which predicts excited hydroxyl (OH*) radiation from the Computational Fluid Dynamics (CFD) solutions of cryogenic hydrogen-oxygen rocket flames. The model of backward ray tracing through inhomogeneous media with a continuously changing refractive index was implemented. READ MORE
