1. 1. Modelling the Exchange Rate: Evidence from the Impacts of Quantitative Easing in Sweden

   University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

   Author : Anny Eklund; Markus Sallkvist; [2024]
   Keywords : Quantitative easing; Exchange rate; Bayesian VAR model; Small open economy; Triangular factorisation;

   Abstract : Quantitative easing, the unconventional monetary policy measure used by many central banks to combat low inflation when interest rates are at the lower bound, has shown to be an effective tool for depreciating the domestic currency. Although the exchange rate is of particular importance in a small open economy as it directly impacts inflation dynamics,trade competitiveness and plays a substantial role in shaping monetary policy, few papers have investigated how the depreciating effect of QE to the exchange rate works.

3. 2. Uncertainty Estimation in Radiation Dose Prediction U-Net

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Frida Skarf; [2023]
   Keywords : 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;

   Abstract : 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. READ MORE

4. 3. Optimization of b-value Acquisition and Parameter Estimation of Intravoxel Incoherent Motion Measurements

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Ivan Rashid; [2023]
   Keywords : Medicine and Health Sciences;

   Abstract : Radiotherapy is commonly used for cancer treatment, given to approximately half of all cancer patients in Sweden. Despite its widespread usage, there is currently no non-invasive and reliable imaging method that can identify regions of radiation resistance. READ MORE

5. 4. Performance Benefits of Extending JavaScript Through WASM and CUDA : A Comparative Performance Investigation

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Hampus Hallkvist; Edvin Nordqvist; [2023]
   Keywords : ;

   Abstract : JavaScript is today the largest language based on usage with regard to web development. There is, therefore, a great incentive to make the language perform at its best and allow applications to take advantage of this. READ MORE

6. 5. Random Edge is not faster than Random Facet on Linear Programs

   University essay from KTH/Matematik (Avd.)

   Author : Nicole Hedblom; [2023]
   Keywords : Simplex method; simplex; Random Edge; Linear Programming; Random Facet; randomized pivoting rule; Markov decision process; Simplexmetoden; Random Edge; linjärprogrammering; Random Facet; Markov-beslutsprocess;

   Abstract : A Linear Program is a problem where the goal is to maximize a linear function subject to a set of linear inequalities. Geometrically, this can be rephrased as finding the highest point on a polyhedron. The Simplex method is a commonly used algorithm to solve Linear Programs. READ MORE
