1. 1. Do viscous flows slip?

   University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

   Author : Björn Sjösvärd; [2023-12-21]
   Keywords : Mathematics; partial differential equations; multivectors; Hodge de-compositions; the Stokes equation; Hodge boun;

   Abstract : In this thesis, the Stokes equation is discussed and solved under different boundary conditions. The Stokes equation governs the flow of viscous liquids, for example honey or syrup. The first chapters in the thesis provides an introduction to multivector algebra and analysis, with the aim of presenting the concept of Hodge decompositions. READ MORE

3. 2. Interaction for flexural column buckling : Analytical procedures compared with FE-simulations

   University essay from KTH/Bro- och stålbyggnad

   Author : Noah Norberg; [2023]
   Keywords : ;

   Abstract : This master's thesis presents a study on the stability of steel structures under flexural bucklingconstraints. The study focuses on the interaction and behaviour of flexural buckling formulas in SSEN-1993-1-1 and Swedish BSK and the performance of actual structural members subjected to suchconstraints.

4. 3. Analysing Regime-Switching and Cointegration with Hamiltonian Monte Carlo

   University essay from Uppsala universitet/Statistiska institutionen

   Author : Jakob Brandt; [2023]
   Keywords : Time Series Econometrics; Regime-Switching; Cointegration; Markov Chain Monte Carlo; Hamiltonian Monte Carlo;

   Abstract : The statistical analysis of cointegration is crucial for inferring shared stochastic trends between variables and is an important area of Econometrics for analyzing long-term equilibriums in the economy. Bayesian inference of cointegration involves the identification of cointegrating vectors that are determined up to arbitrary linear combinations, for which the Gibbs sampler is often used to simulate draws from the posterior distribution.

5. 4. Exploring Near-Field SAR with mmWave Pulsed Coherent Radar

   University essay from Lunds universitet/Matematisk statistik

   Author : Elina Yrlid; [2023]
   Keywords : SAR; Synthetic Aperture Radar; PCR; pulsed coherent radar; radar; mmWave; millimeter-wave; near-field; 60GHz; Technology and Engineering;

   Abstract : This thesis explores the option to apply Synthetic Aperture Radar (SAR) techniques to image near-field targets utilizing mmWave pulsed coherent radar (PCR). The recent development of mmWave radars has broadened the scope for SAR, but there are few concrete examples explaining and demonstrating the fundamental SAR algorithms from a PCR perspective.

6. 5. Compact Digital Track Maps: Enhancing Train Traveller Information at the Crossing of Accuracy and Availability : A comparative analysis of algorithms for generating compact representations of railway tracks

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

   Author : Adam Andersson; [2023]
   Keywords : Train positioning; Digital track map; Digital map generation; Position measurement; Global navigation satellite system; Cartography; Tågpositionering; Digitala spårkartor; Generering av digitala kartor; Positionsmätning; Satellitnavigation; Kartograf;

   Abstract : Trains are constrained to the railway tracks they operate on. This can be leveraged for absolute train positioning, where a train’s position can be mapped onto a digital track map (DTM). Extensive research has been dedicated to enhancing the accuracy of DTMs. READ MORE
