1. 1. Uncertainty Estimation in Radiation Dose Prediction U-Net

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Frida Skarf; [2023]
   Nyckelord :Radiation dose prediction models; U-net; quantile regression; Monte Carlo Dropout; epistemic uncertainty estimation; aleatoric uncertainty estimation; Stråldospredicerande modeller; U-net; kvantilregression; Monte Carlo Dropout; epistemisk osäkerhetsskattning; aletorisk osäkerhetsskattning;

   Sammanfattning : The ability to quantify uncertainties associated with neural network predictions is crucial when they are relied upon in decision-making processes, especially in safety-critical applications like radiation therapy. In this paper, a single-model estimator of both epistemic and aleatoric uncertainties in a regression 3D U-net used for radiation dose prediction is presented. LÄS MER

3. 2. Black Hole Dynamics in Stellar Clusters

   Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Markus Strickert; [2022]
   Nyckelord :Black Holes; Globular Clusters; Dynamics; Intermediate-mass black holes; Simulations; Physics and Astronomy;

   Sammanfattning : Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster.

4. 3. Study of an automated testing procedure with dynamic job scheduling and automatic error handling

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

   Författare :Tom Andersson; [2021]
   Nyckelord :Automation; Testing; Dynamic job scheduling; Automatic error handling; Concept generation; Heuristic rules; Dispatching rules; Branch and bound; A*; Dynamic programming; Beam search; Genetic algorithms; Tabu search; Simulations; C#; Technology and Engineering;

   Sammanfattning : During the production of Axis's cameras, the optics modules have to do a number of tests and calibrations that are performed in different test stations. The test and calibration sequence differs between different models. This has so far been done manually by having operators move the units between test stations. LÄS MER

5. 4. Spillover Effects of Forward Guidance Shocks: How ECB Communication Influences Economic Outcomes in Neighboring Economies

   D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

   Författare :Ingrid Löfman; [2021]
   Nyckelord :Forward Guidance; Monetary Policy Spillover Effects; Central Bank Communication; Exchange Rates; Fear of Floating;

   Sammanfattning : With policy rates at the zero lower bound, the ECB is increasingly relying on forward guidance to stimulate the economy. In this thesis paper, I show that the ECB's communication has important effects on economic outcomes both inside and outside of the eurozone. LÄS MER

7. 5. Analysis of an Ill-posed Problem of Estimating the Trend Derivative Using Maximum Likelihood Estimation and the Cramér-Rao Lower Bound

   Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

   Författare :Muhammad Farhan Naeem; [2020]
   Nyckelord :carbon dioxide levels; Keeling Curve; Taylor and Fourier series; Maximum Likelihood Estimation; MLE; Cramér-Rao Lower Bound; CRLB;

   Sammanfattning : The amount of carbon dioxide in the Earth’s atmosphere has significantly increased in the last few decades as compared to the last 80,000 years approximately. The increase in carbon dioxide levels are affecting the temperature and therefore need to be understood better. LÄS MER
