The usage of powder metallurgy aluminium compacts in lieu of ferrous components in automotives helps to lower vehicle weight. The major drawback in the commercially available press sintered aluminium alloy is porosity which is mainly dependent on the powder metallurgical process parameters such as compaction pressure, sintering temperature and cooling rate after sintering. In this paper the eff...

The background to these notes is the expectation that mathematical modelling and simulation is going to play increasingly important role in the understanding of the organization and control of genetic-, metabolic-, and signalling pathways. I am going to argue that for modelling and simulation to help our understanding of cellular dynamics, the current practice of experimental design has to chan...

a study of the diagenetic evolution of sandstones from panyu low-uplift in the pearl river mouth basin was carried out to unravel the controls on shelf margin sandstone reservoir quality. the reservoir rocks, oligocene volcanic clastic sandstones of the zhuhai formation, have a burial depth of 2765 to 3440 m. 70 samples were studied using the granulometric analyses, x-ray diffraction (xrd) anal...

We investigate expressiveness of a fragment of the ambient calculus, a formalism for describing distributed and mobile computations. More precisely, we study expressiveness of the pure and public ambient calculus from which the capability has been removed, in terms of the reachability problem of the reduction relation. Surprisingly, we show that even for this very restricted fragment, the reach...
