Bounded Cohomology of Groups acting on Cantor sets
(2022)We study the bounded cohomology of certain groups acting on the Cantor set. More specifically, we consider the full group of homeomorphisms of the Cantor set as well as Thompson's group $V$. We prove that both of these groups are boundedly acyclic, that is the bounded cohomology with trivial real coefficients vanishes in positive degrees. Combining this result with the already established $\mathbb{Z}$-acyclicity of Thompson's group $V$, ...Master Thesis -
Network optimization in railway transport planning
(2017)This work is dealing with train timetabling problem. In the first chapter, one can find an introduction to network flows which is needed for understanding deeper concepts later on. Namely, basic graph theory definitions are stated as well as core problems like the minimum cost flow and shortest path problem. Furthermore, two equivalent representations of network flows are described, including some useful properties connected to each of ...Master Thesis -

Implementation of an autonomous taxi service in a multi-modal traffic simulation using MATSim
(2016)Rapportserie för Avdelningen för fysisk resursteoriIn the foreseeable future it will be possible to have self-driving cars in the city environment. A number of simulations have been performed to assess the impact and possibilities of autonomous vehicles, mainly seeing them as a means of public transportation. While previous studies have focused on the replacement of existing private car trips, the interplay between a newly introduced autonomous vehicle taxi service with the existing means ...Master Thesis -
Fine-Tuning of Functionalised MCM-41 for Bio-Oil Upgrading
(2016)The synthesis of solid sulphonic acids by modifying mesoporous silica and their catalytic behaviour in esterification of model compounds for biomass conversion is studied. Conventionally synthesised MCM-41 has a mean pore diameter of 1.9 nm. Larger pore sized MCM-41 was synthesised using techniques such as amine based pore expansion and usage of an auxiliary chemical. The maximal sulphur loading on functionalised siliceous MCM-41 with ...Master Thesis -

Modeling and Implementing High Performance Programs on FPGA
(2016)This work investigates the potential of high performance computing (HPC) on fieldprogrammable gate arrays (FPGAs), highlighting concepts and programming techniques to pursue performance using high level synthesis (HLS) tools. We compute the peak single precision floating point performance on the AlphaData 7V3 board using a model of replicated processing elements, then implement a benchmark to verify the predicted performance in ...Master Thesis
