Vacature PhD position on Regional Economic Spatial Agent-Based Models

PhD position on Regional Economic Spatial Agent-Based Models
The successful candidate will work within the SCALAR research team to explore how interactions between households and firms affect urbanization in the presence of climate-driven risks and how relocation affects regional economic resilience. A set of spatial agent-based models supported by theory and data will be developed on a range of scales. During this 4-year long project, the PhD student will build up on the latest progress in urban agent-based modeling and extend it further by introducing climate adaptation decisions of households and businesses. This modeling effort will benefit from the behavioral data elicited via tailored household surveys (carried out by another team member) and other data. Moreover, moving from urban to large-scale agent-based simulations is an important aspect of this sub-project. Scaling up of agent-based models requires alternative considerations and will benefit from the additional support of a programmer at the later stages of the project. We connect...

PhD position: Rheology, Flow, Phase-separation and Leakage of Lubricating Grease from Rolling Bearings
The Chair Tribology-Based Maintenance, Faculty of Engineering Technology of the University of Twente has an opening for a PhD candidate in the research area of Grease Lubrication. This project operates at the interface of fluid dynamics, rheology, complex fluids and tribology. The expected outcome of this 4-year project will be a model that can predict the (very slow) leakage of base-oil and thickener from rolling bearings. This requires a thorough understanding of the flow and rheology, phase separation and degradation of lubricating greases in rolling bearings. The project is executed in close collaboration with SKF, a leading global bearing manufacturer. THE CHALLENGE Lubricating grease is a visco-elastic material, consisting of a thickener matrix (usually a soap, 5-15%), base oil (mineral or synthetic) and additives (anti-corrosion, anti-wear, 1-5%). At small strains, lubricating grease is apparently solid. This quantity makes grease easy to use: it does not easily leak out of a...

PhD position: Surface manipulation and volume control of cavitation
This PhD project is funded by a Marie SkÅ‚odowska-Curie Innovative Training Network; a joint research training and doctoral programme, funded by the EU and implemented by a partnership of high-profile universities, research institutions, and non-academic organisations that are located in 8 different countries. UCOM is the acronym of the project "Ultrasound Cavitation in sOft Materials". The UCOM network is international (includes beneficiaries and partners from the EU, Switzerland, US, Japan and China), interdisciplinary (mechanical, physics, medical and biomedical technology fields), intersectoral (includes academic and non-academic institutions) and innovative (addresses topics not studied before). 15 doctoral candidates will be recruited by the research-focused organisations of the consortium to develop, improve and validate new state-of-the-art cavitation models and interaction with soft materials (e.g. tissues) against both existing and new experimental data. At the same time,...
