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 -
Analysis of advanced material models for complex industrial processes
(2016)The work presented analyzes a number of associated and non-associated constitutive models and discusses their advantages and disadvantages. Additionally, new models are introduced to attempt to combine the advantages of both methods. To be able to evaluate a large number of models under similar conditions, all models tested have been implemented in a user defined subroutine written in Fortran90 for LS-Dyna. Based on previous work, an ...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 -
Abgrenzung der Wirtschaftlichkeit von lokbespannten Reisezügen gegenüber Triebzügen
(2016)In dieser Arbeit werden Anwendungsfälle abgegrenzt, in denen lokbespannte Reisezüge wirtschaftlicher sind als Triebzüge. Berücksichtigt werden dabei sowohl technische als auch betriebliche Aspekte inklusive Auslastung. Ausgehend von existierendem Rollmaterial sowie basierend auf Fachgesprächen wurde ein Zugmodell entwickelt, mit dem zahlreiche Konfigurationen abbildbar sind. Mithilfe realer Fahrgastzahlen wurde ein generisches Nachfragemodell ...Master Thesis -
