1. 1. Exact Solutions of Soliton Equations and Dynamical Systems

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Fredrik Jonsson; [2023]
   Keywords : ;

   Abstract : This report investigates how one can construct soliton solutions to the following solitonequations: the Korteweg-de Vries equation, the Benjamin-Ono equation, and the spinBenjamin-Ono equation by making rational pole ansätze, which are ansätze that dependon eponymous pole parameters moving in the complex plane. In doing so we demonstratea connection between these soliton solutions and the class of integrable dynamical systemsknown as Calogero-Moser systems. READ MORE

3. 2. Utilization of waste heat from hydrogen production : A case study on the Botnia Link H2 Project in Luleå, Sweden

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Andrea Miljanovic; Fredrik Jonsson; [2022]
   Keywords : PEM electrolyzer; alkaline electrolyzer; waste heat; district heating; LCOH;

   Abstract : The global hydrogen demand is steadily increasing, and one way of accelerating the green hydrogen supply is to stimulate the green hydrogen economy. Utilization of waste heat from hydrogen production can increase the profitability of produced green hydrogen. READ MORE

4. 3. Evaluation of the Transformer Model for Abstractive Text Summarization

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

   Author : Fredrik Jonsson; [2019]
   Keywords : ;

   Abstract : Being able to generate summaries automatically could speed up the spread and retention of information and potentially increase productivity in several fields. Using RNN-based encoder-decoder models with attention have been successful on a variety of language-related tasks such as automatic summarization but also in the field of machine translation.

5. 4. On the Construction of an Automatic Traffic Sign Recognition System

   University essay from Linköpings universitet/Statistik och maskininlärning

   Author : Fredrik Jonsson; [2017]
   Keywords : traffic sign recognition; object detection; image classification; mixture models; Gibbs sampling;

   Abstract : This thesis proposes an automatic road sign recognition system, including all steps from the initial detection of road signs from a digital image to the final recognition step that determines the class of the sign. We develop a Bayesian approach for image segmentation in the detection step using colour information in the HSV (Hue, Saturation and Value) colour space. READ MORE

6. 5. RSA authentication in Internet of Things : Technical limitations and industry expectations

   University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

   Author : Fredrik Jonsson; Martin Tornkvist; [2017]
   Keywords : Internet of Things; RSA; Authentication;

   Abstract : The objective of this thesis is to evaluate if it is possible to run RSA authentication in a specified scenario. A Raspberry Pi with a limited CPU is used to simulate a low-performance device. A series of tests on this device shows that it is not possible to run RSA authentication in the provided scenario.
