  1. 11. Matched Reassignment of the Ultrasound Data of Breast Lesions

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Robert Vujasic; [2022]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : The goal of this thesis was to, from several randomly selected patients with diagnosed malignant and benign tumors, record optimal lambdas and respective Renyi entropies for each lambda, run a basic statistical analysis of the results and see if there is any significant difference between lambdas/Renyi entropies of malignant and benign lesions.\\ The results showed no significant difference.

  3. 12. Simulation of IB-LOCA in TRACE : A semi-blind study of numerical simulations compared to the PKL test facility

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

    Författare :Matilda Tiberg; [2022]
    Nyckelord :Pressurized Water Reactor; Safetey analysis; LOCA; Intermediate Break; PKL; TRACE; transient; thermal hydraulics;

    Sammanfattning : This thesis studied the performance of the thermal hydraulic software TRACE applied on an intermediate sized break (IB) happening on the cold leg in a pressurized water reactor (PWR), causing a loss-of-coolant accident (LOCA). The same accident has previously been simulated in the PKL Test Facility, which is a scaled version of a PWR and is used to simulate transients stemming from different accidents. LÄS MER

  4. 13. Thermal transients study for the ESS target helium cooling system

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Hannes Björk; [2022]
    Nyckelord :ESS; European Spallation Source; models; Modelica; system identification; sensors; cooling system; Technology and Engineering;

    Sammanfattning : The European Spallation Source (ESS) is going to be the worlds most powerful spallation source once in full operation. The neutrons used by scientists and engineers are spallated from a rotating wheel of wolfram, being bombarded by accellerated protons. LÄS MER

  5. 14. Aeroengine transients in altitude test facility

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Baptiste VILLENEUVE; [2022]
    Nyckelord :;

    Sammanfattning : Altitude test facilities offer a safe and reliable way to perform a wide variety of tests on aircraft engine. Among them, aeroengine transients represent a necessary step in the certification and qualification of engines. LÄS MER

  7. 15. Identifying Bluetooth Low Energy Devices via Physical-Layer Hardware Impairments

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Daniel Nilsson; [2022]
    Nyckelord :;

    Sammanfattning : It is desirable to be able to distinguish between Bluetooth Low Energy (BLE) devices purely based on individual hardware imperfections because such imperfections are often prohibitly expensive to imitate. Other works have been done on this topic in the past, which utilized signal transients requiring a multi-GHz sampling rate recorded with costly special equipment to be satisfactorily captured. LÄS MER
