1. Advancements in Dependability Analysis of Safety-Critical Systems : Addressing Specification Formulation and Verification Challenges
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Safety-critical systems have garnered increasing attention, particularly regarding their dependability analysis. In modern times, these systems comprise numerous components, making it crucial to verify that lower-level components adhere to their specifications will ensure the overall system’s compliance with its top-level specification.

2. Decomposing Import Price Inflation in the EU
Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen; Lunds universitet/Statistiska institutionenSammanfattning : This thesis examines what drives import price inflation in the EU by decomposing it into supply and demand driven inflation. The decomposition is done by using product level import data retrieved from Eurostat. The paper examines the period from 2019-01 to 2023-01 which captures events such as the Covid-19 and the war in Ukraine. LÄS MER
3. Nonlinear Methods of Aerodynamic Data-driven Reduced Order Modeling
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskapSammanfattning : Being able to accurately approximate outputs of computationally expensive simulations for arbitrary input parameters, also called missing points estimation, is central in many different areas of research and development with applications ranging from uncertainty propagation to control system design to name a few. This project investigates the potential of kernel transformations and nonlinear autoencoders as methods of improving the accuracy of the proper orthogonal decomposition method combined with regression.

4. Accelerating MCR-ALS decomposition of hyperspectral images using k-means clustering
Kandidat-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisationSammanfattning : A hyperspectral image may be decomposed into component spectra and their distri- bution in the image to simplify analysis by revealing underlying patterns and reducing the dimensionality of the image; this may be achieved by the algorithm MCR-ALS. However, the algorithm is time consuming, but could be accelerated by a data re- duction. LÄS MER
5. Semi-Automatic Analysis and Visualization of Cardiac 4D Flow CT
Master-uppsats, Linköpings universitet/Institutionen för hälsa, medicin och vårdSammanfattning : The data obtained from computational fluid dynamics (CFD) simulations of blood flow in the heart is plentiful, and processing this data takes time and the procedure for that is not straightforward. This project aims to develop a tool that can semi-automatically process CFD simulation data, which is based on 4D flow computed tomography (CT) data, with minimal user input. LÄS MER
