An explicitly time dependent equation for the alpha-effect in mean field dynamo theory is employed to ensure that the magnetic helicity equation for the total (small and large scale) magnetic field is obeyed exactly. The dependence of the turbulent magnetic diffusivity on the field strength is unconstrained by magnetic helicity conservation and is therefore employed as a free parameter. The app...

We discuss the optimal evaluation of endothelial shear stress for real-life case studies based on anatomic data acquisition. The fluid dynamic simulations require smoothing of the geometric dataset to avoid major artefacts in the flow patterns, especially in the proximity of bifurcations. A systematic series of simulations at different corrugation levels shows that, below a smoothing length of ...

As the density of VLSI circuits increases, it becomes attractive to integrate dedicated test logic on a chip. This Built-in Self-Test (BIST) approach not only offers economic benefits but also interesting technical opportunities with respect to hierarchical testing and the reuse of test logic during the application of the circuit. Starting with an overview on test problems, test applications an...

We study the effect of particle cohesion on the steady state shear strength of a granular material. For cohesive powders, the steady state shear loci (termination loci) from DEM simulations are nonlinear with a peculiar pressure dependence due to the non-linear increase of contact adhesion with pressure in the contact model. Physical experiments are carried out on fine limestone powder in the d...

Large-scale coherent rolls are observed frequently in unstably stratified turbulent wall-bounded flows where they influence strongly the transport and mean flow properties. Here we address question of their genesis by means a linear stability analysis model Reynolds stresses is embedded operator. We use channel as testbed for analysis. show that onset large-scale convection associated to instab...

Built-In Self-Test (BIST) techniques constitute an attractive and practical solution to the problem of testing VLSI circuits and systems. Input vector monitoring concurrent BIST schemes perform testing concurrently with the operation of the circuit. In this paper a novel input vector monitoring concurrent BIST scheme is presented that compares favorably to previously proposed schemes with respe...

Among significant components of testing cost are testlength, reject ratio, and lost-yield. In this paper a new approach is proposed to estimate the reject ratio. The empirical model is based on test-data properties that are believed to be invariant for a wide range of manufacturing technologies and types of tests. The analysis is carried out entirely in terms of the device test data, as might b...
