Optimization of oil production may be performed on different time horizons. Long-term optimization (which is typically performed over timescales of years) is usually conducted by reservoir engineers, whereas short-term optimization (which typically concerns days or weeks) is performed by production...

This paper considers path following control of planar snake robots using virtual holonomic constraints. We first derive the Euler-Lagrange equations of motion of the snake robot. Moreover, we integrate the effects of friction forces into these equations. Subsequently, we define geometric relations...

Both goal and threat modelling are well-known activities related to high-level requirements engineering. While goals express why a system is needed, threats tell us why security for our system is needed. Still, you will often find that goals and threats are treated in separate modelling processes...

Some strains of Lactobacillus sakei are known to produce the bacteriocin sakacin P, encoded by the spp gene cluster. In strains unable to produce sakacin P, spp homologues were observed. The analysis of 15 strains not producing sakacin P revealed that all contained a region corresponding to a part...

This thesis aims to accurately describe the plastic anisotropy of aluminium alloys through a hierarchical multi-level method. Robust and efficient integration schemes have been proposed for the explicit numerical integration of rate-dependent crystal plasticity models. On the mesoscale, the...

This paper describes the development of efficient and robust numerical integration schemes for ratedependent crystal plasticity models. A forward Euler integration algorithm is first formulated. An integration algorithm based on the modified Euler method with an adaptive substepping scheme is then...
