6. Adaptive random walks on graphs to sample rare events
University essay from Stockholms universitet/FysikumAbstract : In this thesis, I study fluctuations and rare events of time-additive observables of discrete-time Markov chains on finite state spaces. The observable of interest is the mean node connectivity visited by a random walk running on instances of an Erdős-Rényi (ER) random graph. READ MORE

7. Statistical Analysis and Modelling of Engine Oil Degradation
University essay from Umeå universitet/Institutionen för fysikAbstract : An engine oil has several important properties it must fulfil in order to provide efficient engine operation. In addition to damping friction by lubrication, an engine oil must be able to cool, protect against corrosion, dampen vibrations and clean surfaces from contamination, wear and residual products.

9. Control charts for statistical quality control of Swedish stroke care using Riksstroke data
University essay from Umeå universitet/StatistikAbstract : The aim of this study was to implement statistical quality control to stroke care in Sweden by designing control charts for data from the Riksstroke registry to detect potential unnatural, or special cause variation in the years 2019-2020. Suitable control charts were designed for three quality indicators: the time elapsed from hospital admission to receiving reperfusion therapy (door-to-needle time), the proportion of patients directly admitted to stroke unit, and the fatality rate.

10. Improving Availability of the Pelletization Process
University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälleAbstract : The Grate-Kiln-Cooler process is a commonly used method of sintering during iron ore pelletization, where the pellets are formed, dried, and hardened. The pellets are oxidized in the rotating Kiln, turning magnetite (Fe3O4) to hematite (Fe2O3), making the pellets attain suitable metallurgical attributes for further processing. READ MORE
