Gaspar, F.J. (author), Lisbona, F.J. (author), Oosterlee, C.W. (author)In this work, we present a robust and efficient multigrid solver for a reformulated version of the system of poroelasticity equations. The reformulation enables us to treat the system in a decoupled fashion. It is sufficient to choose a highly efficient multigrid method for a scalar Poisson type equation for the overall solution of this...conference paper 2006

Hartmann, L. (author)It is easy to see whether a system in equilibrium is stable when there are only two forces acting on it, as in a swing. But until recently, this was impossible for an equilibrium involving three forces, as in a hammock. A team of structural engineers at TU Delft have discovered a mathematical method of determining the stability of an equilibrium...journal article 2006

Oosterom, R. (author)The shoulder joint provides us with a large range of motion. This is enabled by the shallowness of the glenoid cavity and the cooperation of many bone elements of the shoulder girdle. This results in complex biomechanics and dependency to surrounding soft tissues for its stability. Due to a fracture or joint diseases, a shoulder replacement may...doctoral thesis 2005

De Vlugt, E. (author)Visco-elasticity of joints is important for the maintenance of the human body posture and can in two manners be regulated. By means of cocontraction of antagonistic muscle groups and by neural reflexive feedback of muscle length and muscle strength, measured both by means of sensors in the muscles. The impact of the reflexive regulation is...doctoral thesis 2004

Hofland, B. (author)The second chapter describes the general methodology of the research. It presents the key questions about the entrainment of stones from granular filters that are as yet unanswered. It also describes the aspects that are being regarded in the analysis in this report. In chapter 3 the measuring set-up is described. The following two chapters...report 2001

Verhagen, H.J. (author)Because of problems with the design guidelines produced by PIANC for armoured slopes under attack by bowthrusters, additional work has been done in the Netherlands. On the basis of this work computational rules have been developed. However, because of the increase of bowthruster power, more detailed knowledge is needed on the effect of a...conference paper 2001
