Adaptive Finite Element Approximation of Fluid-Structure Interaction Based on an Eulerian Variational Formulation

We propose a general variational framework for the adaptive finite element approximation of fluid-structure interaction problems. The modeling is based on an Eulerian description of the (incompressible) fluid as well as the (elastic) structure dynamics. This is achieved by tracking the movement of the initial positions of all `material' points....

Architectural pattern generation by discrete wavelet transform and utilisation in structural design

Since computers were introduced in architectural design as a valuable tool, there was a growing need to develop tools that would support the designer from the initial phase of the design till the detailing. In a computer aided architectural design environment it is feasible to stimulate the spatial design ideas and create alternatives in an...

The use of MEBAS in creating a simulation environment for compression and encryption

In order to get a better sight on the performance of compression and encryption algorithms under various conditions a simulation environment is needed. Within this simulation environment It must be possible to investigate the influence of code tables, channel characteristics and frame formats on the performance of the algorithms. In this report...

Smeared cracking, plasticity, creep, and thermal loading-a unified approach

Heat treatment studies of aluminium alloy forgings of the AZ 74.61 type. Interim report no. 3: Fatigue crack propagation performance under manoeuvre spectrum loading

The fatigue crack propagation performance of the alloy AZ 74.61 under manoeuvre spectrum loading was studied. The crack propagation behaviour was also compared with that of the American forging alloy AA 7050, not only for simulated manoeuvre loading but also for simulated gust loading and programme loading. It was found that, at comparable...

Emerging conflict in collaborative mapping: Towards a deeper understanding?

In spatial planning and environmental management, maps are found very helpful in many situations, but in other situations they may also deepen conflicts or be ignored. This paper addresses the question what explains such phenomena, with particular emphasis on, and reference to, collaborative policymaking settings in the Netherlands. We have...
