  1. 1. Wind Turbine Recovery Forecasting using Survival Analysis

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Anton Palets; [2023]
    Nyckelord :Survival analysis; Recovery Forecast; Wind Turbine; Availability Forecast; AFT model; Aalen s model; Cox regression; Cox Proportional Hazards; Variation Processes; Mathematics and Statistics;

    Sammanfattning : The goal of this thesis is to present a methodology for predicting time until recovery of failed wind turbines. The necessity is motivated by the potential for more accurate wind energy export forecasts. The current approach rests entirely on having an expert examine the turbine and produce a time estimate.

  3. 2. Constructing and commissioning of a Multi-Grid neutron detector prototype for the European Spallation Source

    Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB

    Författare :Rebecka Wahlén; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : A prototype of a novel 10B-based neutron detector called the Multi-Grid detector has been constructed, tested and commissioned for the European Spallation Source (ESS). The detector is constructed after the specifications set by the CSPEC instrument at ESS and is therefore called the CSPEC Multi-Grid detector. LÄS MER

  4. 3. Thermal neutron counting and gamma-ray peak identification from fusion reactions, using a Sodern Genie-16 Neutron Generator

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Auden Ti; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : This thesis work focuses on the categorisation of a Sodern Genie-16 Neutron Generator, at the Nuclear Applications Laboratory, Lund University. To that end, the goals of this work focuses on the re-development of the pre-existing infrastructure surrounding the Sodern Genie-16 Neutron Generator for the purposes of internally irradiating samples, and the subsequent categorisation of the new configuration for extraction of fast neutrons.

  5. 4. Integrated generator for use in aircraft engines

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fredrik Andersson; [2018]
    Nyckelord :Integrated generator; aircraft engine; generator; aircraft generator; Technology and Engineering;

    Sammanfattning : In this paper the use of integrated generators for airplane engines is examined. In order to accomplish this goal a combination of MatLab with FEMM and ANSYS Maxwell is used to make incrementally more and more detailed analysis of the integrated generator concept. LÄS MER

  7. 5. Two-Dimensional Radiation Field Map of a Be-based Source

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Henrik Söderhielm; [2017]
    Nyckelord :Nuclear Physics Particle Detectors Neutrons Gamma Rays European Spallation Source Lund University; Physics and Astronomy;

    Sammanfattning : The aim of this project was to measure the profile of the radiation exiting an aperture of the Aquarium at the Source Testing Facility at the Division of Nuclear Physics at Lund University. So far, the outgoing beam of radiation at the aperture of the Aquarium has been assumed to be uniform. LÄS MER
